This calculator is part of our USA Payroll Tool Calculators hub — a suite of free payroll tools for gross-up, 1099 self-employment, bonuses, and overtime.
See the gross pay required for different net amounts, states, and filing statuses. All calculations use 2026 tax rates per IRS Rev. Proc. 2025-32 with progressive federal brackets, the 2026 standard deduction ($16,100 single / $32,200 MFJ), and FICA.
| Desired Net | Gross Pay Required | Effective Tax Rate |
|---|---|---|
| $1,000 | $1,082.84 | 7.7% |
| $2,500 | $2,707.09 | 7.6% |
| $5,000 | $5,414.19 | 7.7% |
| $7,500 | $8,121.28 | 7.7% |
| $10,000 | $10,828.37 | 7.6% |
No state income tax. Only FICA (7.65%) applies at these income levels because the 2026 standard deduction ($16,100) eliminates federal taxable income below that threshold.
| Desired Net | Gross Pay Required | Effective Tax Rate |
|---|---|---|
| $1,000 | $1,204.09 | 16.9% |
| $2,500 | $3,010.23 | 16.9% |
| $5,000 | $6,020.47 | 16.9% |
| $7,500 | $9,030.71 | 17.0% |
| $10,000 | $12,040.94 | 17.0% |
9.3% state income tax + FICA (7.65%). Federal tax = $0 at these income levels due to the $16,100 standard deduction.
| Desired Net | Gross Pay Required | Effective Tax Rate |
|---|---|---|
| $1,000 | $1,180.64 | 15.3% |
| $2,500 | $2,951.59 | 15.3% |
| $5,000 | $5,903.19 | 15.3% |
| $7,500 | $8,854.78 | 15.3% |
| $10,000 | $11,806.38 | 15.3% |
Self-employment tax (15.3%) applies. No state tax. Federal income tax = $0 at these levels due to the $16,100 standard deduction. Note: the deductible half of SE tax is not reflected here.
| Desired Net Bonus | Gross Bonus Required | Tax Withholding |
|---|---|---|
| $500 | $710.73 | $210.73 |
| $1,000 | $1,421.46 | $421.46 |
| $2,500 | $3,553.67 | $1,053.67 |
| $5,000 | $7,107.32 | $2,107.32 |
| $10,000 | $14,214.64 | $4,214.64 |
22% flat federal withholding + 7.65% FICA = 29.65% total. No state tax (Texas example). State tax also applies in most states.
How to read these tables: To net $5,000 as a single W-2 employee in Texas, you need a gross of $5,414.19. At this income level the 2026 standard deduction of $16,100 eliminates federal income tax entirely — only FICA (7.65%) applies. For higher incomes where federal income tax kicks in, effective rates rise. Use the calculator above for your exact scenario.
A gross-up paycheck is when an employer increases an employee's gross wages so that after all tax withholdings — federal income tax, state income tax, and FICA (Social Security and Medicare) — the employee receives a specific net amount. The employer "grosses up" the pay to cover the taxes.
Gross-up is a reverse payroll calculation. Instead of starting with gross pay and subtracting taxes to find net pay (the standard direction), you start with the desired net pay and work backward to determine the gross pay required.
The gross-up formula is: Gross Pay = Net Pay / (1 - Total Tax Rate).
The fundamental gross-up formula is simple: divide the desired net pay by 1 minus the total tax rate.
Gross Pay = Desired Net Pay / (1 - Total Tax Rate)
Where Total Tax Rate = Federal Income Tax Rate + State Income Tax Rate + FICA Rate
The following uses a simplified flat-rate assumption to illustrate the formula. The actual calculator uses progressive brackets and the correct 2026 standard deduction (see below).
Step 1: Identify the tax rates (simplified illustration)
Step 2: Apply the formula
Step 3: Verify the result
Important: The example above uses a simplified flat-rate federal tax assumption for illustration. In reality, federal income tax uses progressive brackets, and the 2026 standard deduction ($16,100 for single filers) reduces taxable income. For a single employee in Texas earning $5,414 gross, the standard deduction eliminates all federal taxable income — only FICA (7.65%) applies. Our calculator handles progressive brackets, the standard deduction, and FICA automatically.
Now let's calculate the gross pay needed for a single employee in California (9.3% state income tax) using the same simplified flat-rate illustration.
Step 1: Identify the tax rates (simplified)
Step 2: Apply the formula
The difference between states is significant. State income tax rates are a critical factor in gross-up calculations. Use the calculator above for precise results with actual progressive brackets.
One of the most common payroll mistakes is assuming that grossing up is as simple as adding the tax rate percentage to the net amount. This is the Gross-Up Trap.
The Mistake: Adding 29.65% to $5,000 = $6,482.50
The Problem: After taxing $6,482.50 at 29.65%, the net would only be $4,560.44 — not $5,000.
Why It Fails: The tax is calculated on the gross amount, including the tax itself. It's a compounding effect.
The Correct Formula: Gross = Net / (1 - Tax Rate) = $5,000 / 0.7035 = $7,107.32
The formula Gross = Net / (1 - Total Tax Rate) works well for flat tax rates. But federal income tax is progressive — different portions of your income are taxed at different rates (10%, 12%, 22%, 24%, 32%, 35%, and 37% in 2026). Additionally, the standard deduction ($16,100 for single filers, $32,200 for MFJ in 2026 per IRS Rev. Proc. 2025-32) reduces taxable income before brackets apply.
Because the tax rate depends on the gross pay itself, the calculation becomes iterative. Our calculator must:
This is exactly what our calculator does automatically. It converges to within $0.01 accuracy, typically within 10–20 iterations.
Accurate gross-up calculations depend on current tax rates. Below are the key 2026 federal rates, FICA, and state income tax highlights. All figures are verified against IRS Rev. Proc. 2025-32 and IRS Publication 15 (2026).

| Social Security | 6.2% | 12.4% | $184,500 |
| Medicare | 1.45% | 2.9% | No limit |
| Additional Medicare (high earners) | 0.9% (wages over $200k single / $250k MFJ) | 0.9% (over $200k/$250k) | – |
Social Security wage base is $184,500 for 2026 (up from $176,100 in 2025). Additional Medicare applies to wages over $200,000 (single) or $250,000 (married filing jointly). Employers must begin withholding Additional Medicare once an employee's wages exceed $200,000 in a calendar year, regardless of filing status.
The standard deduction reduces taxable income before bracket calculations apply. For 2026 (per IRS Rev. Proc. 2025-32):
The flat 2026 federal withholding rate for supplemental wages paid separately from regular wages is 22%, per IRS Publication 15 (2026). This applies to bonuses, commissions, overtime, severance, and other supplemental pay when paid separately from regular wages. Supplemental wages exceeding $1,000,000 in a calendar year are subject to mandatory 37% withholding on the excess. Note: the calculator applies the 22% flat rate and does not apply the 37% rate to amounts over $1,000,000. For calculating taxes on bonus payments specifically, try our calculate bonus tax withholding.
State taxes vary widely. The calculator includes 2026 state income tax rates for all 50 states and D.C. using a single average/flat rate per state (progressive state brackets, state standard deductions, and state credits are not modeled). Here are the extremes:
Local income taxes (e.g., in Pennsylvania, Ohio, Indiana) are not included in this calculator. Consult a tax professional for precise local withholding.
Follow these steps to get an accurate gross-up calculation for any scenario. The calculator handles progressive 2026 federal taxes (IRS Rev. Proc. 2025-32), state income tax, FICA, and pre-tax deductions automatically.
These examples show how gross-up works in common payroll situations. All numbers are calculated using 2026 tax rates (IRS Rev. Proc. 2025-32), the correct 2026 standard deduction, and the calculator's iterative method.
Setup: A new hire is promised a $10,000 net signing bonus. The employer wants to gross up the payment so the employee receives exactly $10,000 after taxes. The employee is single, 0 allowances (post-2020 W-4), works in Texas (no state tax).
Calculation result:
Takeaway: The employer's total cost for a $10,000 net bonus in Texas is $10,828.37. Because gross is below the $16,100 standard deduction, only FICA (7.65%) applies. The extra $828.37 covers FICA taxes.
Setup: An employee is relocating to California. The employer agrees to cover $5,000 in moving expenses and wants the employee to net the full $5,000. The employee is married filing jointly, 2 allowances (pre-2020 W-4 on file), works in California (9.3% state rate).
Calculation result:
Takeaway: California's 9.3% state tax adds significant cost. The employer must pay $6,020.47 to deliver $5,000 net — about 20% more than the net amount.
Setup: An employer gives a $500 gift card as a performance award. Gift cards are taxable as supplemental wages. The employer wants to gross up so the employee nets $500 after the 22% flat federal tax and FICA. The employee is in Texas (no state tax). For self-employed individuals estimating their own tax burden, our UK self-employment tax estimator covers UK self-employment tax, and our US 1099 contractor tax calculator covers US self-employment tax.
Calculation result:
Takeaway: With the 22% flat federal rate plus 7.65% FICA, the total withholding rate is 29.65%. The gross-up multiplier is 1.4215x — meaning every dollar promised nets 70.35 cents without grossing up.
Setup: An employee wants to maximize their 401(k) contribution by having their entire bonus go directly to the 401(k), netting $0 in cash. The employer grosses up the bonus so that after taxes and the 401(k) contribution, the employee's net cash is $0, but the 401(k) receives the full contribution.
Note on 2026 401(k) limits: The 2026 elective deferral limit for 401(k), 403(b), and most 457 plans is $24,500 (up from $23,500 in 2025). Catch-up contributions for employees age 50+ are $8,000, for a combined limit of $32,500. Employees aged 60–63 have a higher catch-up limit of $11,250.
For this scenario, note that the online calculator requires a desired net greater than $0 (a $0 target returns a validation message). Enter a small net target (e.g., $0.01) with the desired pre-tax 401(k) percentage, or compute the figures manually, to approximate the gross amount that achieves a $0 cash net. This is complex and depends on contribution limits — we recommend consulting a tax advisor or payroll professional.
Takeaway: Gross-up can be used to maximize retirement contributions while minimizing cash outlay, but the math is intricate and depends on contribution limits.

=Net_Pay / (1 - Total_Tax_Rate) in a cell.
Many people confuse gross-up with standard payroll processing. They are opposite directions of the same equation.
You start with the employee's gross pay (salary or hourly rate). You subtract federal income tax, state tax, FICA, and other deductions. The result is the employee's net pay (take-home). This is the "forward" calculation. For quick gross-to-net paycheck calculations, see our calculate take-home pay from gross salary.
Formula: Net = Gross – Taxes – Deductions
Example: Gross = $6,000 → Federal tax $800 → State tax $300 → FICA $459 → Net = $4,441
You start with the desired net pay. You work backward to determine the gross pay required to achieve that net after taxes and deductions. This is the "reverse" calculation.
Formula: Gross = Net / (1 – Tax Rate) (iterative for progressive brackets)
Example: Desired Net = $5,000 → Calculate Gross = $5,414.19 (Texas, single, 2026) → FICA only = $414.19
| Aspect | Regular Payroll (Gross-to-Net) | Gross-Up (Net-to-Gross) |
|---|---|---|
| Direction | Forward (Gross → Net) | Reverse (Net → Gross) |
| Used for | Normal salary payments, hourly wages | Bonuses, relocation, severance, gift cards |
| Tax calculation | Straightforward: apply rates to known gross | Iterative: gross depends on tax, which depends on gross |
| Employer cost | Known from salary amount | Must be calculated to meet net target |
| Employee perspective | "What will I take home from this salary?" | "What salary do I need to take home X?" |
Regular payroll is linear: you know the gross, so you can calculate taxes exactly in one pass. Gross-up is nonlinear because the tax rate depends on the gross, which is unknown. That's why an iterative method (or a calculator like ours) is required.
Most gross-up calculators use a single flat-rate assumption. You enter a tax rate, and they divide the net by (1 − that rate). It's simple, but it's also inaccurate for most real-world payroll scenarios.
This calculator combines progressive federal tax brackets, the 2026 standard deduction, all 50 state tax rates, and FICA simultaneously.
The 2026 standard deduction ($16,100 single / $32,200 MFJ per IRS Rev. Proc. 2025-32) is subtracted from gross pay before any bracket calculations. This means many lower-income employees pay zero federal income tax — only FICA. Calculators that ignore the standard deduction systematically overstate federal tax and therefore overstate the gross-up amount.
The federal income tax system uses progressive brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Only the portion of income above each threshold is taxed at that rate. This calculator applies the actual 2026 progressive brackets to every calculation.
State income taxes can be 0% (Texas, Florida, Nevada) or over 13% (California). Ignoring state taxes can massively underestimate gross-up costs. Our calculator includes 2026 state tax rates for every state, using a simplified average/flat rate per state (progressive state brackets, state standard deductions, and credits are not modeled).
W-2 employees pay 7.65% FICA (employee share, with employer covering the other half). Independent contractors (1099) pay 15.3% self-employment tax — both halves. Our toggle lets you switch between W-2 and 1099 instantly.
Pre-tax deductions reduce taxable income, which affects the gross-up required. Our calculator lets you enter 401(k) percentage, health insurance premiums, HSA contributions, and other pre-tax deductions. The iterative engine accounts for these in every calculation.
Bonuses, commissions, and severance paid separately from regular wages are subject to a flat 22% federal withholding rate (2026 IRS Publication 15). Our calculator includes a toggle to switch between regular wages and supplemental wages.
Our engine converges to the exact gross amount within $0.01 tolerance, typically in 10–20 iterations. We display the iteration count so you know the result is precise.
Every result includes a "Gross-Up Trap" warning that explains why simply adding the tax rate to your net amount fails. This educational component prevents costly payroll errors.
A gross-up paycheck is when an employer increases an employee's gross wages so that after all tax withholdings — federal income tax, state income tax, and FICA (Social Security and Medicare) — the employee receives a specific net amount. The employer "grosses up" the pay to cover the taxes. This is commonly used for sign-on bonuses, relocation reimbursements, severance packages, and gift cards.
The basic gross-up formula is Gross Pay = Net Pay / (1 − Total Tax Rate). Total Tax Rate includes federal income tax, state income tax, and FICA. For progressive federal tax brackets, the calculation is iterative because the taxable income (after the standard deduction) determines the rate, which depends on the gross being calculated. The 2026 standard deduction is $16,100 (single) and $32,200 (MFJ) per IRS Rev. Proc. 2025-32. This calculator handles all of this automatically.
The 2026 federal supplemental wage tax rate is 22%, per IRS Publication 15 (2026). This flat rate applies to bonuses, commissions, overtime, severance, and other supplemental wages paid separately from regular wages. The alternative is the aggregate method, where supplemental wages are combined with regular wages and normal withholding applies. Supplemental wages exceeding $1,000,000 in a calendar year are subject to mandatory 37% withholding on the excess.
Yes. Bonuses are considered supplemental wages and are subject to a flat 22% federal withholding rate (2026, per IRS Pub. 15) when paid separately from regular wages. Regular wages are taxed using progressive brackets based on your W-4 filing status and the applicable standard deduction. State tax treatment of bonuses varies by state.
To gross up in Excel, use the formula =Net_Pay / (1 − Total_Tax_Rate) for
flat-rate calculations. For progressive tax brackets, build a bracket lookup table matching
the 2026 thresholds from IRS Rev. Proc. 2025-32, then apply the standard deduction before
bracket calculations. Use Excel's Goal Seek (Data → What-If Analysis → Goal Seek) or enable
iterative calculations (File → Options → Formulas → Enable iterative calculation) to solve
for gross pay automatically.
The 2020 redesigned Form W-4 eliminated withholding allowances entirely. Employees who submitted a W-4 in 2020 or later cannot claim withholding allowances — those fields no longer exist on the form. The allowance system (where each allowance reduces taxable wages by approximately $4,300 annually in 2026) only applies to employees who have an unrevised pre-2020 W-4 on file. For most employees today, the W-4 Allowances field in this calculator should be left at 0.
Employees who live in one state and work in another may be subject to tax withholding in both states, depending on reciprocity agreements. Generally, taxes are withheld in the state where work is performed. Some states (like California) require non-resident withholding if an employee works in the state, even if they live elsewhere. States with reciprocity agreements (e.g., Pennsylvania and New Jersey) may allow the employee to only pay tax in their state of residence. Consult a tax professional for multi-state payroll situations — this is a complex area.
Yes. Pre-tax deductions reduce taxable income, which affects the gross-up calculation. This calculator allows you to enter 401(k) contribution percentage, health insurance premiums, HSA contributions, and other pre-tax deductions. The iterative engine accounts for these deductions to accurately determine the gross pay needed to achieve the desired net pay.
The gross-up trap is the common mistake of simply adding the tax rate percentage to the net amount. For example, adding 30% to $1,000 gives $1,300, but after taxes at 30%, the net is only $910 — not $1,000. The correct formula is Gross = Net / (1 − Tax Rate), which yields $1,428.57 for a 30% rate. The calculator includes a "Gross-Up Trap" warning with every result to help you avoid this mistake.
Gross-to-net calculates net pay from gross pay (forward direction). You start with a known gross salary and subtract taxes and deductions to find net take-home. Gross-up (net-to-gross) calculates gross pay needed to achieve a specific net pay (reverse direction). Gross-up is used when an employer promises a specific net amount, such as a $5,000 net bonus. These are opposite directions of the same equation.
Nine states have no state income tax on wages as of 2026: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. (New Hampshire taxes only interest and dividends, not wages.) These states simplify gross-up calculations by removing state income tax from the equation. However, local city or county taxes may still apply in some areas.
The 2026 Social Security wage base limit is $184,500 (up from $176,100 in 2025), per IRS Publication 15 and the SSA wage base announcement. Wages above this amount are not subject to Social Security tax (6.2% employee, 6.2% employer). Medicare tax (1.45% each) continues on all wages with no limit. The calculator automatically applies the wage base limit in all calculations.
In principle, yes, but it is an advanced use case, and the online calculator requires a desired net amount greater than $0 (entering $0 triggers a validation message). A $0 net means all wages are withheld for taxes and pre-tax deductions, sometimes used to maximize retirement contributions (e.g., 401(k) deferral — limit is $24,500 for 2026) while keeping cash net at $0. To model it, enter a small net target (e.g., $0.01) or run the math manually, and confirm the employee has enough gross wages to cover taxes and deductions. Minimum wage laws may restrict how low net pay can go.
This calculator uses the following methodology to ensure accurate, IRS-compliant results.

The gross-up result above is the employee's gross wages. The employer's total cost is higher because employers also pay payroll taxes — and often a 401(k) match — on the grossed-up amount:
Example: For a grossed-up annual gross of $100,000 in Texas (no state income tax), employer-side payroll taxes add roughly $7,650 (6.2% Social Security + 1.45% Medicare) plus FUTA on the first $7,000 — before any 401(k) match or benefits loading. Budget for gross pay + employer-side taxes + benefits, not gross pay alone.
The calculator models employee-side taxes and returns the grossed-up gross amount; it does not model employer-side payroll taxes. Add those when budgeting your true compensation cost.
