The short answer: Under Ohio's 20-day rule (ORC 718.011), an employer is not required to withhold municipal income tax for a nonresident employee working in a municipality until the employee works there on more than 20 days in a calendar year. Withholding begins on the employee's 21st day in that municipality, and the day count resets to zero every January 1.
Calculate Your Ohio 20-Day Withholding Threshold
Enter the employee's first day of work in the municipality and their current day count to determine whether the 20-day withholding threshold under ORC 718.011 has been reached — and on which date withholding must begin.
The first calendar day the employee performed services in this municipality during the current calendar year.
Count only days where the employee spent more time in this municipality than in any other municipality that day (ORC 718.011(B)(2) preponderance test).

Instant Answer: When Does Withholding Begin?
Here are eight common scenarios showing how the Ohio 20-Day Withholding Threshold applies to nonresident employees. Use these examples to understand when your withholding obligation starts.
| Scenario | Days Worked in Municipality | Threshold Reached? | Withholding Required? | Withholding Starts On |
|---|---|---|---|---|
| Scenario 1 | 10 days | No | Not Yet | Day 21 if threshold crossed |
| Scenario 2 | 20 days | No (at threshold) | Not Yet | Day 21 if employee returns |
| Scenario 3 | 21 days | Yes | Yes — Day 21 | Day 21 (current and all subsequent) |
| Scenario 4 | 25 days | Yes | Yes — Day 21+ | Day 21 (5 days overdue if not yet started) |
| Scenario 5 | 5 days — construction site expected >20 days | Yes (worksite exception) | Yes — Day 1 | First day (presumed worksite location) |
| Scenario 6 | 18 days — small employer (<$500K receipts) | N/A | Simplified Rule | Withhold only for employer's fixed location |
| Scenario 7 | Any — professional athlete/entertainer/public figure | N/A (exception) | Yes — Day 1 | First day (20-day threshold does not apply) |
| Scenario 8 | 15 days — employee is a resident of this municipality | N/A (exception) | Yes — Day 1 | First day (resident exception applies) |
How the Threshold Works
Under ORC 718.011(B)(1), an employer is not required to withhold municipal income tax for a nonresident employee working in a municipality for 20 or fewer days in a calendar year. Once the employee works a 21st day, withholding is mandatory for that day and all subsequent days in the same calendar year.
Key rule: Withholding begins on Day 21 in the municipality
Example: An employee first works in Columbus on February 3 and accumulates 20 days by April 15. On April 16 (Day 21), the employer must begin withholding Columbus municipal income tax on qualifying wages paid for services performed in Columbus.
Note: The 20-day count resets to zero on January 1 each calendar year. Days from a prior year do not carry over.
What Is the Ohio Municipal 20-Day Rule?
The Ohio Municipal 20-Day Rule (Ohio Revised Code § 718.011) is a withholding threshold for employers. It establishes that an employer is not required to withhold municipal income tax on qualifying wages paid to a nonresident employee for services performed in a municipality if the employee worked in that municipality on 20 or fewer days in a calendar year.
Once the employee crosses the 20-day threshold — that is, works a 21st day in that municipality during the same calendar year — the employer must begin withholding and remitting municipal income tax to that municipality for all subsequent days of work there in that year.
Key Takeaway: The 20-day rule is a withholding exemption, not a payment deadline. It determines when an employer must start withholding municipal income tax for a nonresident employee — not when to pay a terminated employee. Employers who have nonresident employees working in multiple Ohio municipalities must track days carefully to know when withholding obligations are triggered.
Who Does the 20-Day Rule Apply To?
The rule applies to any employer with a fixed location in Ohio that pays qualifying wages to employees who perform services in Ohio municipalities. The employee whose days are being tracked must be a nonresident of the municipality in question — that is, they live and have their principal place of work elsewhere.
If the employee's principal place of work is in the municipality, withholding is always required regardless of the number of days worked there. The 20-day threshold only applies to occasional or visiting work in a non-principal-place-of-work municipality.
| Situation | 20-Day Threshold Applies? | When Withholding Starts |
|---|---|---|
| Nonresident employee, non-principal municipality | Yes | Day 21 in that municipality |
| Employee's principal place of work | No — always withheld | Day 1 |
| Construction/temporary worksite (>20 days expected) | No — presumed worksite exception | Day 1 |
| Professional athlete, entertainer, or public figure | No — statutory exception | Day 1 |
| Employee is a resident of the municipality | No — resident exception | Day 1 (if employee requests) |
| Small employer (<$500K total revenue — ORC 718.01(TT)) | Not applicable — simplified rule | Withheld only for employer's fixed location |
Why Does the 20-Day Rule Exist?
Before Ohio's Amended Substitute House Bill 5 (signed December 19, 2014; effective for tax years beginning January 1, 2016), the occasional entrant rule was set at 12 days. HB5 expanded that threshold to 20 days and standardized the rule statewide across all Ohio municipalities, replacing a patchwork of local ordinances with uniform Chapter 718 requirements. This change was designed to reduce compliance complexity for employers with employees who work across multiple Ohio cities.
The rule also protects nonresident employees from being taxed in municipalities where their presence is limited. By allowing up to 20 days of presence before withholding is required, the rule exempts workers on short business visits from incurring local tax obligations in every city they set foot in.
How Does the 20-Day Rule Work?
The rule is built around a day-counting threshold that resets every calendar year. Here is a step-by-step explanation of how it operates.
The Day-Count Threshold Explained
Each calendar year, an employer tracks how many days a nonresident employee performs services in each municipality. Days are accumulated using the preponderance test (explained in the next section). Once the employee's day count in a municipality exceeds 20, withholding must begin for that municipality.
Example Timeline
- Days 1–20 in Municipality X: No withholding required for Municipality X. Tax is withheld only for the employee's principal place of work municipality during this period.
- Day 21 in Municipality X: Withholding threshold is crossed. The employer must begin withholding and remitting municipal income tax to Municipality X.
- Day 22+ in Municipality X (same year): Withholding continues for Municipality X for all subsequent days of work there in that calendar year.
For example, if an employee whose principal place of work is Dayton begins working project days in Cincinnati on January 10, 2026, and accumulates 20 Cincinnati days by March 18, 2026, the employer must begin withholding Cincinnati municipal income tax starting on the 21st Cincinnati day.
What Happens at the Threshold?
Under ORC 718.011(D)(1), once the 20-day threshold is exceeded, the employer must withhold and remit tax to the municipality for any subsequent days in that calendar year on which qualifying wages are paid to the employee for services performed in that municipality.
Under ORC 718.011(D)(2), the employer may also elect to withhold retroactively for the first 20 days. If the employer makes this election, taxes already withheld and paid to the principal-place-of-work municipality for those first 20 days become refundable to the employee.
Important: There is no automatic retroactive withholding obligation. By default, withholding for the new municipality begins only from Day 21 forward. Days 1 through 20 are not subject to mandatory retroactive withholding. The retroactive election under ORC 718.011(D)(2) is optional for the employer.
Calendar Year Reset
The 20-day threshold resets to zero on January 1 each calendar year. An employee who worked 22 days in Columbus in 2025 — triggering Columbus withholding on days 21 and 22 — starts fresh at zero days in Columbus on January 1, 2026. The employer must again track days in Columbus in 2026 and restart withholding only after the 20-day threshold is crossed again in the new year.
Annual Reset: The day count does not carry over from year to year. Each calendar year is treated independently for the 20-day threshold calculation.
What Counts as a "Day" Under the Rule?
Under ORC 718.011(B)(2), a day counts toward a municipality's threshold only if the employee spent more time performing services in that municipality than in any other single municipality on that day. This is often called the preponderance test.
This means each calendar day can count toward at most one municipality's day total — whichever municipality had the most hours of service from the employee that day. An employee working across three cities in one day accumulates one day toward the city where they spent the most time.
Important: travel time is specifically addressed in ORC 718.011(B)(2). Time spent traveling to the first worksite of the day, traveling between worksites, and traveling home from the last worksite is counted toward the employee's principal place of work, not the destination municipality.
What Counts as a "Day" Under the 20-Day Rule?
Not all hours worked in a municipality count the same way. The determination of what constitutes a qualifying "day" is governed by the preponderance test under ORC 718.011(B)(2). This test determines which municipality gets credit for the employee's work on any given calendar day.
A day counts toward a municipality only if the employee spent more time performing services in that municipality than in any other municipality on that specific day. An employee can accumulate a day toward at most one municipality per calendar day.
Key Rule: A day is counted in the municipality where the employee performed the greatest amount of service time that day compared to every other municipality — not simply where they spent more than half the day. If an employee works 4 hours in City A, 3 hours in City B, and 1 hour in City C, that day counts in City A (most time spent there).
How the Preponderance Test Works
The preponderance test is applied individually to each calendar day. Employers must determine, for each day a mobile employee works, which single municipality received the most hours of active service.
Preponderance Test Scenarios
Scenario A: Employee works 6 hours in Columbus and 2 hours in Dublin.
→ Day counts in Columbus (6 hours > 2 hours — most time in Columbus)
Scenario B: Employee works 3.5 hours in Cincinnati and 4.5 hours in Norwood.
→ Day counts in Norwood (4.5 hours > 3.5 hours — most time in Norwood)
Scenario C: Employee works 4 hours in Akron, 3 hours in Cuyahoga Falls, and 1 hour in Stow.
→ Day counts in Akron (4 hours > 3 hours and 1 hour — most time in Akron)
Scenario D: Employee works 4 hours in Cleveland and 4 hours in Lakewood (exact tie).
→ Day determined by principal place of work allocation — employer allocates using a fair and reasonable method per ORC 718.011(A)(7).
Travel Time Rules
ORC 718.011(B)(2) specifies how travel time is handled. The following types of travel time are counted toward the employee's principal place of work, not toward any transit municipalities:
- Traveling to the location where the employee will first perform services for the day
- Traveling between service locations during the day
- Traveling to pick up or load property for transportation or delivery
- Transporting or delivering that property (where the employee does not affix it to another party's real estate)
- Traveling from the final delivery or pick-up location back to the principal place of work or a non-service location
This means a delivery driver who spends two hours driving through various municipalities before reaching their first service stop has that travel time attributed to their principal place of work — reducing the hours that count toward any individual transit municipality.
Partial Days and Multiple Municipalities
The preponderance test applies to each day independently. You cannot aggregate partial-day hours across a week or month. Each specific calendar day is evaluated on its own.
This prevents double-counting: even if an employee visits five municipalities in a single day, only one municipality accumulates a day in its running count — the one where the employee spent the most service time.

Who Does the 20-Day Rule Apply To?
The Ohio Municipal 20-Day Rule under ORC 718.011 applies to any employer with a fixed location in Ohio that pays qualifying wages to nonresident employees performing services across multiple Ohio municipalities. This includes private businesses, non-profit organizations, and most public employers.
The rule applies to the employee's work location, not their residence. A nonresident employee — someone whose principal place of work is in a different municipality than the one they are visiting for work — is subject to the 20-day threshold for each non-principal municipality where they perform services. If your employees work in multiple Ohio cities, the Ohio local income tax credit calculator can help them determine their potential tax credits.
Employers Covered
- Private businesses with Ohio fixed locations
- Non-profit organizations paying qualifying wages
- Public employers (subject to ORC 9.42 for deductions)
- Staffing agencies with Ohio employees
- Contractors sending workers to multiple cities
- Multi-location employers with roving employees
Who Is Not Subject to the Standard 20-Day Rule?
Several categories of employers or employees are carved out from the standard threshold. These exceptions are important to understand because they affect when withholding begins.
- Small employers — those with total revenue under $500,000 in the preceding taxable year use a simplified withholding rule (withhold only for fixed location municipality); government entities are excluded from this definition regardless of revenue (ORC 718.011(E); ORC 718.01(TT))
- Professional athletes, entertainers, and public figures — withholding starts on Day 1; the 20-day threshold does not apply (ORC 718.011(B)(1)(d))
- Employees who are residents of the municipality — if the employee requests withholding, it starts on Day 1 (ORC 718.011(B)(1)(c)). See the Ohio local tax reciprocity credit calculator for credit rules when home and work cities differ.
- Construction and temporary worksites — where services are expected to last more than 20 days, withholding begins on Day 1 (ORC 718.011(B)(1)(b))
- Petroleum refineries — a 12-day threshold applies instead of 20 (ORC 718.011(G))
- Employees under age 18 — fully exempt from Ohio municipal income tax in all municipalities effective tax year 2024 (ORC 718.01(C)(15); HB 33, 135th GA).
- Work performed in non-taxing locales — no withholding required where the locale imposes no municipal income tax (ORC 718.011(B)(1))
Petroleum Refinery Exception: For employees working at an Ohio petroleum refinery (SIC code 2911), the threshold is 12 days — not 20. If the 12-day threshold is exceeded, the employer must withhold for the first 12 days and all subsequent days in that calendar year (ORC 718.011(G)).
Special Case: Hybrid and Remote Workers
For remote workers, each day's location matters. A remote employee working from their home address on a given day contributes that day's hours to the municipality of their home address (if it is an Ohio municipality with an income tax). ORC 718.011(A)(6) specifically states that an employee's home is not a "worksite location" for purposes of the presumed worksite exception — which means the regular 20-day threshold applies to remote work from a home municipality.
Hybrid Work Scenario Examples
Scenario A: Employee works 5 hours from home (Cincinnati) and 3 hours at the employer's office (Covington, KY — out of state).
→ Day counts in Cincinnati (5 hours > 3 hours; home is not a worksite location per ORC 718.011)
Scenario B: Employee works 2 hours from home (Columbus) and 6 hours at a client site (Dublin).
→ Day counts in Dublin (6 hours > 2 hours)
Scenario C: Employee works 4 hours from home (Akron) and 4 hours at the office (Akron — same municipality).
→ Both sets of hours count in Akron (same municipality; total of 8 hours there)
Exceptions to the 20-Day Rule
ORC 718.011 contains several exceptions that override or modify the standard 20-day withholding threshold. Employers must understand these exceptions because misapplying them can result in under-withholding and exposure to penalties.
Full List of Exceptions
Small Employer Simplified Rule
Employers with total revenue under $500,000 in the preceding taxable year (as reported on their federal tax return) and a fixed location in Ohio must withhold only for the municipality where their fixed location sits — regardless of where employees work. This is not a full exemption; withholding is still required, just simplified. Government entities — including the federal government, state governments, state agencies, political subdivisions, and entities treated as governments for financial reporting — are explicitly excluded from this definition under ORC 718.01(TT) and cannot use this simplified rule.

Presumed Worksite Location (Construction)
If an employer provides services at a construction site or other temporary worksite that can reasonably be expected to last more than 20 days, withholding for that municipality begins on Day 1. This applies from the start of services, not retrospectively. A worksite is "presumed" to exceed 20 days if the nature of the services requires it or the customer agreement requires more than 20 days of actual services.
Source: ORC 718.011(B)(1)(b)
Professional Athletes, Entertainers & Public Figures
Professional athletes, professional entertainers, and public figures (such as paid speakers at discrete events) are not entitled to the 20-day threshold. Withholding begins on Day 1 for qualifying wages paid in connection with their professional capacity. "Professional entertainer" means a person performing in the professional performing arts on a per-event basis; "public figure" means a person of prominence performing at discrete events on a per-event basis.
Source: ORC 718.011(A)(2)–(4); ORC 718.011(B)(1)(d)
Employee Resident of the Municipality
If the employee is a resident of the municipality in question and requests that the employer withhold tax from their qualifying wages under ORC 718.03, the 20-day threshold does not apply. Withholding begins on Day 1 upon the employee's request.
Source: ORC 718.011(B)(1)(c)
Petroleum Refinery — 12-Day Threshold (ORC 718.011(G))
Employees performing services at an Ohio petroleum refinery (Standard Industrial Classification code 2911 — petroleum refining) are subject to a 12-day threshold instead of 20. If exceeded, the employer must withhold for the first 12 days and all subsequent days in that calendar year in which the individual performs services at the refinery.
Source: ORC 718.011(G)
Minors Under Age 18 — Fully Exempt (Effective Tax Year 2024)
Beginning with tax year 2024, the income of all individuals under 18 years of age is exempt from Ohio municipal income tax in all municipalities. No withholding is required for employees under age 18 for any Ohio municipality. This exemption was enacted by HB 33 (135th GA, signed July 3, 2023) and confirmed by RITA. For tax years 2016–2023, minors were generally subject to municipal income tax.
Source: ORC 718.01(C)(15); HB 33 — 135th GA, effective tax year 2024; RITA guidance
No Local Tax in Municipality — No Withholding Required
An employer does not have to withhold any municipal income tax for qualifying wages paid for work performed in a locale that does not impose a municipal income tax. Many Ohio townships and unincorporated areas have no local income tax. An employee's days in a non-taxing locale do not count toward any threshold.
Source: ORC 718.011(B)(1); RITA Occasional Entrant Flowchart
Employer Voluntary Opt-In — Withhold from Day 1
A non-small employer may voluntarily choose to disregard the occasional entrant rules entirely and begin withholding from Day 1 for any municipality. This optional approach simplifies payroll administration by eliminating per-employee day tracking. If the employer opts in and withholds from Day 1, those amounts are not refundable to the employee under ORC 718.011(D)(2).

Tax Administrator Agreement
If a tax administrator and an employer enter into an agreement regarding the manner in which the employer shall comply with ORC 718.03 withholding requirements, the standard 20-day threshold rules under ORC 718.011(B)(1) and (D) may not apply to the extent specified in that agreement.
Source: ORC 718.011(F)
Understanding the Small Employer Simplified Rule
The small employer rule under ORC 718.011(E) and ORC 718.01(TT) is the most frequently encountered exception. It is designed to reduce compliance complexity for small businesses, but it is not a full exemption from withholding. Small employers still must withhold municipal income tax — they simply do so only for the municipality where their fixed Ohio location sits, regardless of where employees actually work.
How It Works: An employer qualifies as a "small employer" under ORC 718.01(TT) if their total revenue for the preceding taxable year was under $500,000 and they have a fixed location in Ohio. "Total revenue" under ORC 718.01(TT) is broadly defined to include all receipts of any type — sales, payments, rents, profits, gains, dividends, grants, contributions, tuition, reimbursements, and any other similar receipts reported for federal income tax purposes or under GAAP. A tax administrator may require the employer to provide their prior year's federal income tax return to verify eligibility.
Note: ORC 718.011 uses the term "small employer as defined in section 718.01" — the definition at 718.01(TT) is the controlling one (last updated September 30, 2025 by HB 96, 136th GA).
Government entities are excluded: The federal government, any state government (including any state agency or instrumentality), any political subdivision, and any entity treated as a government for financial accounting and reporting purposes are explicitly excluded from the "small employer" definition under ORC 718.01(TT), regardless of their revenue. This means cities, townships, counties, school districts, and state agencies cannot use the simplified withholding rule.
| Employer | Prior Year Total Revenue (ORC 718.01(TT)) | Small Employer Rule Applies? | Withholding Obligation |
|---|---|---|---|
| ABC Consulting LLC | $425,000 | Simplified Rule | Withhold only for employer's fixed location municipality |
| XYZ Manufacturing Inc. | $625,000 | Standard Rule | Track and withhold per 20-day threshold for each municipality |
| City of Springfield (govt.) | N/A | Excluded from Small Employer | Standard rule applies; government entities cannot use simplified rule |
| Regional Logistics Co. | $750,000 | Standard Rule | Track and withhold per 20-day threshold for each municipality |
Important: The small employer simplified rule is determined annually based on the prior year's total revenue as reported on the employer's federal income tax return (ORC 718.011(E); ORC 718.01(TT)). If your total revenue exceeds $500,000 in the current year, the standard 20-day tracking rule applies starting the next taxable year. Monitor your revenue each year to determine which rule applies.
How to Track Employee Days Across Municipalities
Tracking employee days across multiple municipalities is the most challenging part of complying with Ohio's 20-Day Rule. Without a systematic tracking approach, employers risk missing the threshold and failing to begin withholding on time.
Step-by-Step Tracking Methodology
Establish a Daily Location-Tracking System
Implement a time-tracking system that captures work location by hour for each calendar day. This can be digital (time-clock software with location fields) or a spreadsheet. The key is capturing municipality-level detail — not just city name, but the specific municipal taxing jurisdiction.
Apply the Preponderance Test Each Day
For each calendar day, compare hours worked in each municipality. Assign the day to the municipality with the most service hours. Exclude travel time to first worksite, between worksites, and return travel — those hours go to the principal place of work. Document your reasoning.
Maintain a Running Day Total Per Municipality
Keep a running count of days attributed to each municipality for each employee, resetting to zero on January 1 each year. This running total is what you compare against the 20-day threshold.
Set Up Threshold Alerts
Create alerts at day 18, 19, and 20 for each employee-municipality combination. This gives you time to update your payroll system to begin withholding before Day 21 arrives. Missing the start date means potential under-withholding liability.
Document Everything for Audit Readiness
Retain daily location logs, preponderance test determinations, and running totals for each employee. Ohio tax administrators can audit withholding records. Documentation is your defense in the event of a challenge.

Note: In this example, Smith has 2 days in City A, 1 day in City B, and 1 day in City C. No municipality has reached the 20-day threshold. Withholding continues only for the employee's principal place of work municipality.

Common Tracking Challenges
- Employee Compliance: Employees may forget to log work locations. Regular reminders and clear instructions help. Consider daily location check-ins.
- Travel-Heavy Roles: Sales reps and delivery drivers who move between municipalities daily require more intensive tracking. Time-clock apps with GPS features can help automate location capture.
- Remote and Hybrid Workers: Remote workers' home municipality counts as their work location on remote days. Ensure employee home addresses are coded as municipalities in your system.
- Mid-Year Hires: New hires who join mid-year start at zero days — the threshold does not carry over from prior employers.
- Audit Readiness: Retain all tracking records for at least three to four years to cover Ohio's statute of limitations periods.
2022 Reinstatement: What Changed?
The Ohio Municipal 20-Day Rule was reinstated on January 1, 2022 after being suspended during the COVID-19 pandemic. Many employers still operate under outdated assumptions from the suspension period. Understanding what changed is critical for compliance.
Current Status: The 20-Day Rule is fully active and enforceable. Any employer who has not updated their payroll practices since 2022 is at significant risk of non-compliance.
Historical Timeline
HB5 Expands the Rule from 12 to 20 Days
Ohio House Bill 5 was signed on December 19, 2014, and expanded the occasional entrant rule from 12 days to 20 days. The change took effect for municipal income tax years beginning January 1, 2016. HB5 also standardized the rule statewide across all Ohio municipalities under Chapter 718.
HB 197 — Emergency Suspension (Signed March 27, 2020)
Governor DeWine signed House Bill 197 on March 27, 2020. Section 29 froze each employee's principal place of work to where it was on March 9, 2020 (the date of the state of emergency declaration) and directed employers to disregard the 20-day rule. Employers could continue withholding to the pre-pandemic principal place of work. The Ohio stay-at-home order expired May 31, 2020; the state of emergency was formally lifted June 18, 2021. Section 29 applied through 30 days after the emergency ended, leaving employers in a compliance gap for the remainder of 2021.
HB 110 — Employer Withholding Options Through December 31, 2021 (Signed July 1, 2021)
House Bill 110, signed July 1, 2021, gave employers two options through December 31, 2021: (1) continue withholding for the pre-pandemic principal place of work, or (2) reassign the employee to a new principal place of work and withhold for the new location. HB 110 also explicitly authorized employees to file refund claims for days worked outside their assigned principal city in 2021 only. Beginning January 1, 2022, the standard ORC 718.011 20-day rule was reinstated in full.
Rule Reinstated — January 1, 2022
The 20-day rule was reinstated on January 1, 2022. The suspension ended, and all employers became subject to ORC 718.011 again. Employers must track days based on actual employee work location. This remains the current state of the law.
What the Reinstatement Means for Employers
Employers who relied on the HB197/HB110 withholding exception must now determine where each employee actually works each day and apply the 20-day threshold accordingly. Withholding for the pre-pandemic principal place of work municipality is no longer automatically permitted for employees who have since moved or shifted to remote work.

Risks of Non-Compliance With the 20-Day Rule
Failing to begin withholding municipal income tax at the correct time exposes employers to several categories of risk. These risks exist regardless of whether the under-withholding was intentional.
What Happens If an Employer Fails to Begin Withholding on Day 21?
When an employer fails to start withholding on Day 21, the employer may be held liable for the taxes that should have been withheld, along with applicable penalties and interest. Use our Ohio employer municipal tax late penalty calculator to estimate what you may owe. Penalties and interest are assessed by the municipal tax administrator or collection agency (such as RITA or CCA). The employee may also separately owe the tax directly to the municipality.
Unpaid Tax Liability
The employer may be liable for taxes that should have been withheld and remitted to the municipality, even if the employee ultimately pays them. Both parties can face assessment.
Penalties and Interest
Municipal tax administrators (RITA, CCA, or local) can assess late-filing penalties and interest on under-withheld amounts. Use our RITA penalty and interest calculator to estimate what you may owe. Penalty rates and structures vary by municipality.
Audit Risk
Non-compliance with withholding rules increases audit exposure. Audits can uncover additional compliance gaps and extend liability to multiple employees or tax years.
Employee Disputes
Employees who are assessed tax they believed was being withheld may seek reimbursement or file complaints with tax authorities, creating additional employer liability.
Multi-Employee Exposure
A systematic failure to track days — rather than a one-off error — can result in simultaneous liability for multiple employees, multiplying total exposure significantly.
Retroactive Assessment Periods
Ohio's statute of limitations for municipal income tax assessments can extend several years. Systemic under-withholding discovered in an audit can result in multi-year back assessments.
How to Avoid Non-Compliance
- Track days accurately: Implement a systematic tracking process for each employee across all municipalities where they perform services.
- Set up alerts: Create alerts in your payroll system when an employee reaches day 18, 19, and 20 in any municipality.
- Update payroll promptly: On Day 21, your payroll system must be configured to withhold and remit to the new municipality.
- Document your methodology: Keep daily records of work location decisions and preponderance test determinations.
- Consult a tax professional: For multi-state or complex situations, work with a CPA or employment tax attorney familiar with Ohio municipal tax.
Proactive Tip: The best approach is to start tracking on Day 1 for every employee in every municipality. The 20-day threshold is a floor — tracking from the start ensures you never miss the withholding trigger date.
What to Do If You Have Already Missed the Threshold
If you discover that you should have started withholding but did not, the recommended steps are: consult a qualified Ohio municipal tax advisor immediately, calculate the under-withheld amounts for each affected employee and municipality, contact the relevant municipal tax authority (RITA, CCA, or the local municipality) to discuss voluntary disclosure, and update your payroll and tracking systems going forward. Voluntary disclosure often results in reduced penalties compared to assessment following an audit.
Remittance Schedule After Withholding Begins
Once you begin withholding for a municipality, ORC 718.03(B) sets how often the withheld tax must be remitted. If the total withheld for the municipality in the preceding calendar year exceeded $2,399 — or exceeded $200 in any month of the preceding quarter — remittance is monthly, due by the 15th day after the end of each month. If the preceding year's total exceeded $11,999 (or any single month exceeded $1,000), remittance is semimonthly. When the 20-day threshold adds a new municipality to your payroll, confirm its remittance cadence with that tax administrator as part of your Day-21 setup.
Why This Is the Only Dedicated Ohio 20-Day Rule Calculator
Search results for "Ohio Municipal 20-Day Payroll Rule Calculator" are filled with generic payroll calculators and legal articles. None of them actually calculate the withholding threshold trigger for you. That is exactly why we built this tool.
Most payroll calculators are designed for take-home pay or federal tax withholding. Legal articles explain ORC 718.011 but leave employers to figure out the day-count math themselves. Neither helps you know exactly when you must start withholding for a specific municipality — and that is the practical question every Ohio employer with mobile employees faces.
The Gap: Before this page, there was no dedicated tool that combined a comprehensive guide to ORC 718.011 with an interactive calculator that tracks employee days and tells you exactly when withholding begins. That gap is now closed.

Frequently Asked Questions About the Ohio 20-Day Rule
Find answers to the most common questions about Ohio's Municipal 20-Day Withholding Rule under ORC 718.011. If you don't see your question answered here, use the calculator above or consult a qualified professional.
The Ohio Municipal 20-Day Rule (ORC § 718.011) is a withholding threshold rule. It provides that an employer is not required to withhold municipal income tax on qualifying wages paid to a nonresident employee for services performed in a municipality if the employee worked in that municipality on 20 or fewer days in a calendar year. Once the employee works a 21st day in the municipality, the employer must begin withholding and remitting municipal income tax to that municipality for all subsequent days of work there during that calendar year. The rule was established under Amended Substitute House Bill 5, effective for tax years beginning January 1, 2016, and reinstated on January 1, 2022 after a COVID-era suspension.
Under ORC 718.011(B)(2), a day counts toward a municipality only if the employee spent more time performing services in that municipality than in any other single municipality on that specific day. This is the preponderance test. For example, if an employee works 5 hours in Columbus and 3 hours in Dublin on the same day, that day counts as one day in Columbus — not Dublin. Travel time to a first worksite, between worksites, and returning from the final worksite is attributed to the employee's principal place of work, not the transit or destination municipalities.
Small employers — defined under ORC 718.01(TT) as employers with total revenue under $500,000 in the preceding taxable year who have a fixed location in Ohio — use a simplified withholding rule under ORC 718.011(E). Instead of tracking days across municipalities, they withhold municipal income tax only for the municipality where their fixed Ohio location is, regardless of where employees work. "Total revenue" under ORC 718.01(TT) is broadly defined to include all receipts of any type: sales, payments, rents, profits, gains, dividends, grants, contributions, reimbursements, and any other receipts reported for federal income tax purposes or under GAAP. This is not a full exemption — withholding is still required. Important: government entities (federal government, state governments, state agencies, political subdivisions such as cities, townships, and counties, and entities treated as governments for financial accounting purposes) are explicitly excluded from the "small employer" definition under ORC 718.01(TT) and cannot use this simplified rule, regardless of their revenue. The definition was last updated September 30, 2025 by HB 96 (136th GA).
Under ORC 718.011(D)(1), once an employee's days in a municipality exceed 20, the employer must withhold and remit municipal income tax to that municipality starting on Day 21 and for all subsequent days of qualifying wages paid in that municipality in the same calendar year. There is no mandatory retroactive withholding for the first 20 days. However, under ORC 718.011(D)(2), the employer may elect to also withhold retroactively for the first 20 days; if this optional election is made, taxes already withheld for those 20 days from the principal place of work municipality become refundable to the employee.
Yes. The 20-day threshold resets to zero on January 1 of each calendar year. An employee who accumulated 22 days in a municipality in 2025 — triggering withholding on days 21 and 22 — starts fresh at zero days in that municipality on January 1, 2026. The employer must again track days in 2026 and restart withholding only after the threshold is crossed again in the new year. Days do not carry over between calendar years.
No. Professional athletes, professional entertainers, promoters of professional events, and public figures (such as paid speakers at discrete events) are not entitled to the 20-day threshold under ORC 718.011(B)(1)(d). Withholding begins on Day 1 for qualifying wages paid in connection with their professional capacity. This exception also extends to employees of such promoters. These individuals are subject to municipal income tax from their first day of performance in any Ohio municipality that imposes an income tax.
Yes. The 20-day rule applies to hybrid and remote workers based on where they actually perform services each day. A remote employee working from their home contributes that day's hours to the municipality of their home address (if it is an Ohio taxing municipality). Note that under ORC 718.011(A)(6), an employee's home is not a "worksite location" for purposes of the presumed worksite exception — so the regular 20-day threshold applies to remote work from home, not the Day-1 worksite exception. Employers should capture the specific municipality of each employee's home address in their payroll records.
These are two different statutes with different purposes. ORC § 718.011 (the subject of this page) is the "occasional entrant exemption" — the withholding threshold rule that governs when employers must begin withholding municipal income tax for nonresident employees working in a municipality. ORC § 9.42 is a separate and older statute that simply requires the state and its political subdivisions to deduct municipal income tax from the wages of public employees. ORC 9.42 does not contain the 20-day threshold, does not govern private employers, and does not create a penalty for late final wage payments.
The 20-Day Rule was reinstated on January 1, 2022. It had been suspended during the COVID-19 pandemic under HB 197 (signed March 27, 2020), which froze each employee's principal place of work to where it was on March 9, 2020 and directed employers to disregard the 20-day rule. Ohio's state of emergency was formally lifted June 18, 2021; HB 197 Section 29 expired 30 days after that. HB 110 (signed July 1, 2021) then gave employers withholding options through December 31, 2021 and authorized 2021 employee refund claims. Effective January 1, 2022, ORC 718.011 applies in full — employers must withhold based on actual day-by-day work location. There are no ongoing pandemic-related suspensions or exceptions.
By default, there is no mandatory retroactive withholding for the first 20 days. Under ORC 718.011(D)(1), withholding for the municipality begins starting on Day 21 and continues for all subsequent qualifying wage payments for services in that municipality in the same year. However, under ORC 718.011(D)(2), an employer may optionally elect to also withhold for the first 20 days. If the employer makes this election, taxes already withheld and remitted for those 20 days to the principal-place-of-work municipality become refundable to the employee.
A special 12-day threshold applies to employees performing services at an Ohio petroleum refinery (Standard Industrial Classification code 2911) under ORC 718.011(G). If an employee works more than 12 days at the refinery, the employer must withhold tax for the first 12 days and for all subsequent days during that calendar year. This exception applies only when the employee's principal place of work is in a different Ohio municipality that imposes income tax on the compensation earned at the refinery, and the employee is not otherwise liable to the refinery municipality for that compensation.
Ohio Amended Substitute House Bill 5 was signed by Governor Kasich on December 19, 2014. The ORC 718.011 statutory text became effective March 23, 2015. However, the practical operational effective date for employers and municipalities was January 1, 2016 — HB5 required all Ohio municipalities levying income tax to amend their ordinances to conform to the new Chapter 718 rules by January 1, 2016. Before HB5, the occasional entrant exemption was 12 days (set locally by each municipality). HB5 standardized it at 20 days statewide.
Yes, beginning with tax year 2024. Ohio House Bill 33 (135th GA, signed July 3, 2023, and enacted in ORC 718.01(C)(15)) provides that the income of all individuals under 18 years of age is exempt from Ohio municipal income tax in all municipalities. Effective January 1, 2024, no withholding is required for employees under age 18 for any Ohio municipality. This exemption applies statewide across all RITA, CCA, and independently administered municipalities. For tax years 2016 through 2023, minors were not automatically exempt under state law (though some individual municipalities had local exemptions). If you employ workers under 18, confirm their birthdate is on file so you can correctly apply the exemption.
Yes. A non-small employer may voluntarily choose to disregard the occasional entrant rules entirely and begin withholding municipal income tax from Day 1 for any Ohio municipality where employees perform services. According to RITA's Occasional Entrant Flowchart (the official guidance document), "An employer who is not a small employer can choose to disregard the Occasional Entrant Rules and withhold from the first day on all wages earned for work performed in an 'occasional entrant' municipality." This opt-in approach simplifies administration because it eliminates the need to track days for the threshold — though it may increase withholding complexity for employees who work in many municipalities. There is no statutory prohibition on this approach under ORC 718.011.
ORC 718.011 is an employer withholding rule that applies to employees whose compensation is reported on Form W-2. Independent contractors who receive non-wage (Form 1099) compensation are not covered by this withholding rule. However, Ohio's municipal income tax rules provide an analogous occasional-entrant treatment for them: non-wage compensation earned inside a taxing municipality on 20 or fewer days in a calendar year is treated as earned — and taxed — at the contractor's base of operation, or at the contractor's domicile if there is no base of operation, rather than in each municipality where services are performed. This treatment does not apply if the individual is a resident of the municipality, if the individual's base of operation is located in that municipality, or if the compensation is paid for services in the individual's capacity as a professional athlete, professional entertainer, or public figure (RITA Occasional Entrant Flowchart; OSCPA Municipal Income Tax Withholding Q&A; Ohio Municipal League guidance).
Methodology: How This Calculator Works
This calculator is built on the statutory framework of Ohio Revised Code § 718.011 (Occasional Entrant Exemption). Every calculation reflects the actual withholding threshold rules that employers in Ohio must follow.
Calculation Logic
Input Collection
The calculator collects three inputs: the first day the employee worked in the municipality during the current calendar year, the total number of days (preponderance-test qualified) the employee has worked in that municipality in the current year, and an optional municipality name for labeling results.
Threshold Comparison
The calculator compares the day count against the 20-day statutory threshold. If days worked are 20 or fewer, withholding is not yet required for that municipality. If days worked exceed 20, the threshold has been crossed and withholding is required.
Days Remaining Calculation
If the threshold has not yet been crossed, the calculator shows how many additional days of work in the municipality would trigger withholding. This helps employers plan ahead and set up alerts before Day 21 arrives.
Withholding Start Status
The result clearly indicates whether withholding is "Not Yet Required," "Withholding Must Begin Now (Day 21+)," or provides actionable information about which day withholding will begin based on the current count.
