What Is Form IT-2104?
Form IT-2104 — officially called the Employee's Withholding Allowance Certificate — is the New York State form you give your employer to tell them how much state income tax to withhold from your paycheck. It works alongside your federal W-4 form, but the two are not the same.
New York State requires employers to withhold state income tax from every employee's wages. The amount withheld depends on the allowances you claim on Form IT-2104. More allowances mean less tax withheld and a larger paycheck today. Fewer allowances mean more tax withheld and potentially a larger refund when you file your taxes.
Every New York employee must complete Form IT-2104 when starting a new job. You can also update it anytime your personal or financial situation changes — marriage, divorce, birth of a child, or a second job, for example.
⚠️ Important: New York State does not allow you to claim yourself or your spouse as allowances on Form IT-2104. Only dependents and specific credits count. This is a key difference from the federal W-4.
The form has three main parts:
- Part 1: New York State and Yonkers withholding allowances
- Part 2: New York City withholding allowances (for NYC residents only)
- Part 3: Additional withholding (if you want extra tax taken out)
If you live in New York City or Yonkers, you also pay local income taxes. These are calculated using the same taxable income but at different rates. The calculator on this page handles both automatically.
For a complete breakdown of every line on the form, see the official IT-2104 instructions from the NYS Department of Taxation and Finance.
Why Your IT-2104 Matters More Than You Think
Many people treat Form IT-2104 like a simple formality — fill it out once, hand it to your employer, and forget about it. That mistake can cost you hundreds or even thousands of dollars.
Claim Too Many Allowances → You Owe at Tax Time
If you claim too many allowances, your employer withholds less tax. That means larger paychecks throughout the year, but you risk owing money when you file your state tax return. If the underpayment is large enough, you may also face penalties and interest.
Claim Too Few Allowances → You Give the State a Free Loan
If you claim too few allowances, your employer withholds more tax. You'll get a larger refund at tax time, but that's money you could have used throughout the year. Over-withholding essentially gives the state an interest-free loan from your paycheck.
⚠️ Penalty Warning: Under-withholding can trigger penalties. NYS law imposes a $500 penalty for each false statement made on Form IT-2104. Additionally, if your withholding falls below certain thresholds, you may owe interest on the unpaid tax.
The 2026 Changes You Need to Know
Form IT-2104 was revised for tax years beginning on or after January 1, 2026, under Chapter 59 of the Laws of 2025. Key changes include:
- Reduced tax rates — five of the nine bracket rates were cut by 0.1 percentage point, with a further 0.1-point cut scheduled for 2027
- Updated withholding tables — employers must use the new NYS-50-T-NYS (1/26) tables
- Revised worksheet logic — the allowance calculation method changed
- Extended high-earner brackets — the 9.65%, 10.30%, and 10.90% rates are extended through 2032
If you filed Form IT-2104 before 2026, you should complete a new form to apply the updated rates. Using outdated allowances means your withholding will be incorrect — either too high or too low.
What's New for 2026 on Form IT-2104
2026 brings significant changes to New York State income tax withholding under Chapter 59 of the Laws of 2025. If you're still using 2025 allowances, you're likely overpaying. Here's what changed.
1. Updated Tax Brackets and Rates
New York's progressive tax system has nine brackets for 2026, with rates ranging from 3.90% to 10.90%. Five of the lower rates were reduced by 0.1 percentage point from 2025. The top rate of 10.90% (income over $25 million) is unchanged.
| Rate | Single / MFS (up to) | Married Joint (up to) | Head of Household (up to) |
|---|---|---|---|
| 3.90% | $8,500 | $17,150 | $12,800 |
| 4.40% | $11,700 | $23,600 | $17,650 |
| 5.15% | $13,900 | $27,900 | $20,900 |
| 5.40% | $80,650 | $161,550 | $107,650 |
| 5.90% | $215,400 | $323,200 | $269,300 |
| 6.85% | $1,077,550 | $2,155,350 | $1,616,450 |
| 9.65% | $5,000,000 | $5,000,000 | $5,000,000 |
| 10.30% | $25,000,000 | $25,000,000 | $25,000,000 |
| 10.90% | Above $25M | Above $25M | Above $25M |
Source: NYS-50-T-NYS (1/26) — effective January 1, 2026 (Chapter 59 of the Laws of 2025). Rates shown are marginal rates applied to taxable income in each bracket.
⚠️ Supplemental Recapture Tax: If your NY adjusted gross income exceeds $107,650, New York requires an additional supplemental tax computation that claws back the benefit of lower-bracket rates. This calculator does not compute the supplemental tax. Affected taxpayers should use the official IT-201 worksheet or consult a tax professional.
2. Standard Deduction Amounts
The 2026 standard deduction amounts used for withholding purposes are:
- Single / Married Filing Separately: $8,000
- Married Filing Jointly: $16,050
- Head of Household: $11,200
3. NYC and Yonkers Rates
NYC resident tax rates (3.078%–3.876%) and Yonkers resident surcharge (16.75% of NY State tax) are unchanged from prior year for 2026.
📌 What to do: If your withholdings are based on 2025 rates, complete a new Form IT-2104 as soon as possible. Use the calculator above as a starting point, then confirm with the official worksheet.
How Many Allowances Should You Claim on IT-2104?
This is the single most common question about Form IT-2104. The answer depends entirely on your personal situation. Here's a step-by-step guide — but always verify your final number with the official IT-2104 worksheet.
What Counts as an Allowance on IT-2104?
Unlike the federal W-4, New York State does not allow you to claim yourself or your spouse. Only these items count toward allowances:
- Dependents: Children or other qualifying dependents you claim on your tax return
- Child care credits: If you qualify for the NYS child care credit
- College tuition credits: NYS college tuition tax credits
- Earned Income Tax Credit (EITC): If you qualify for the NYS EITC
✅ Quick Rule of Thumb: Single filer with no dependents in NYC = claim 0 allowance. Married with 2 kids outside NYC = claim 2 allowances as a starting point (add more if you qualify for credits). The calculator above provides a simplified starting estimate — always confirm with the official worksheet.
Step-by-Step Decision Guide
Step 1: Start With Your Dependents
Count your qualifying dependents. This is your baseline. Example: Single with 1 child = 1 allowance baseline.
Step 2: Adjust for Multiple Jobs
If you have more than one job, or your spouse works, reduce your allowances to avoid under-withholding.
Step 3: Adjust for NYC or Yonkers
NYC and Yonkers residents should reduce allowances to cover local taxes.
Step 4: Consider High Income
If your taxable income exceeds $107,650, you may owe supplemental recapture tax — consider reducing allowances or withholding additional amounts.
Step 5: Confirm With the Official Worksheet
The official IT-2104 includes a detailed worksheet that accounts for credits, multiple income sources, and other factors. The calculator above is a simplified estimate — the worksheet gives you the authoritative number.
💡 Tip: If you're unsure, err on the side of more withholding (fewer allowances). It's better to get a refund than to owe money and penalties at tax time.
Step-by-Step: How to Fill Out Form IT-2104 for 2026

When to Submit a New IT-2104
Common Mistakes to Avoid
- ❌ Claiming yourself or your spouse: NY does not allow this.

- ❌ Forgetting to update after a life change.
- ❌ Claiming too many allowances: Leads to under-withholding and potential penalties.

📌 Important: You are a NYC or Yonkers resident if you maintain a permanent place of abode there and spend more than 183 days (i.e., 184 or more days) in the city during the tax year. Part-year residents may owe a partial tax.
NYC Resident Tax (2026)
NYC imposes a progressive income tax on residents. Rates range from 3.078% to 3.876%, depending on taxable income and filing status.
| NYC Taxable Income — Single / MFS | MFJ / Surviving Spouse | Head of Household | Rate |
|---|---|---|---|
| $0 – $12,000 | $0 – $21,600 | $0 – $14,400 | 3.078% |
| $12,001 – $25,000 | $21,601 – $45,000 | $14,401 – $30,000 | 3.762% |
| $25,001 – $50,000 | $45,001 – $90,000 | $30,001 – $60,000 | 3.819% |
| Over $50,000 | Over $90,000 | Over $60,000 | 3.876% |
Source: NYS Department of Taxation and Finance — NYC tax rate schedules. Rates apply to NYC taxable income by filing status.
Yonkers Resident Surcharge (2026)
Yonkers imposes a surcharge equal to 16.75% of your NY State tax liability on residents. This is calculated as a percentage of state tax owed, not a direct percentage of taxable income.
💡 Tip for NYC and Yonkers Residents: If you're unsure about your allowances, choose one fewer than estimated. Local taxes can be significant, and it's better to withhold a little extra than to owe at tax time.
IT-2104 vs. Federal W-4: What's the Difference?
When you start a new job, you fill out two separate withholding forms: the federal W-4 (for IRS) and the New York IT-2104 (for NYS). They are not the same.
Key Differences
| Feature | Federal W-4 | NY IT-2104 |
|---|---|---|
| System | Dollar amounts (no allowances since 2020) | Allowance-based system |
| Self / Spouse allowance | Accounted for via filing status | Not permitted |
| Standard Deduction — Single (2026) | $16,100 | $8,000 |
| Standard Deduction — MFJ (2026) | $32,200 | $16,050 |
| Standard Deduction — HOH (2026) | $24,150 | $11,200 |
Federal standard deductions per IRS Rev. Proc. 2025-32 (2026 tax year). NY standard deductions per NYS Dept. of Taxation and Finance.
⚠️ Warning: Never copy your federal W-4 allowances to your IT-2104. The rules are completely different. Using the wrong allowance number can lead to significant under-withholding or over-withholding.
