Commission Paycheck Calculator (2026)

How the Commission Paycheck Calculator: Take-Home Pay Works

This commission paycheck calculator turns a base salary plus commissions into an estimate of take-home pay after 2026 federal income tax, Social Security, Medicare and state tax. It also compares the flat 22% federal withholding that many employers use for commission checks with the extra tax your commissions actually cause, so you can tell whether you are over-withheld or under-withheld before you file. Enter your annual base pay and expected commissions, pick a pay frequency and filing status, and press the button.

How commission is taxed

Commissions are wages. They are subject to federal income tax, Social Security, Medicare and state income tax exactly like a regular salary, and they count toward your total annual income for bracket purposes. What differs is withholding. The IRS treats commissions as supplemental wages, so an employer can either combine the commission with your regular pay and withhold as if the total were a regular paycheck, or withhold a flat 22% federal rate on the commission alone. Supplemental wages above $1 million in a year are withheld at 37%. Neither method changes your final tax; both are estimates that are reconciled when you file.

Because your federal brackets are marginal, the tax your commissions really cost depends on where your base salary leaves you. A salesperson with a $40,000 base is taxed at 12% on much of the commission and 22% on the rest, so a flat 22% withholding usually takes too much and produces a refund. A salesperson near the top of the 24% bracket may be under-withheld by the flat method. Read bonus tax explained for the same rules applied to bonuses.

Worked example: $40,000 base plus $30,000 commission

A single filer in a state with no income tax earns a $40,000 base salary and $30,000 in commissions, for total pay of $70,000. Federal taxable income after the $16,100 standard deduction is $53,900, and federal income tax is about $6,570. Without the commission, tax on the base alone would be about $2,620, so the commission adds roughly $3,950 of federal tax, an effective rate of 13.2% on the commission. A flat 22% withholding would take $6,600 from those commission checks, or $2,650 more than the tax the commission really caused, which comes back as part of a refund.

FICA of $5,355 applies to the full $70,000, leaving net pay of about $58,075 a year, or $2,233.65 per biweekly paycheck. Change the numbers above to see how different commission levels affect the result.

When flat 22% withholding helps and hurts

Flat withholding is simple for payroll, but it can misjudge your real bracket. If your total income falls in the 12% bracket, 22% withholding is far too high on commissions, and you will wait until tax season to recover the difference. If your income is in the 24% or 32% bracket, 22% is too low, and you may owe when you file. With a $90,000 base and $60,000 in commissions, for example, the commission adds about $13,764 of federal tax, while flat 22% withholding would be $13,200, so the flat method under-withholds by about $564. If your commission income is large or uneven, use the W-4 withholding calculator to add extra withholding or make estimated payments.

Commission-only, draws and irregular income

Many sales roles pay a draw against future commissions, which employers treat as an advance of wages, and some jobs are commission-only. Draws are taxed when paid, not when commissions are earned, and a repayment of an unearned draw can complicate the year-end totals. Independent contractors who earn commission on a 1099 receive no withholding at all, owe both halves of Social Security and Medicare, and must pay quarterly estimated taxes; use the self-employment tax calculator in that case. Irregular income also makes budgeting harder, so plan around your lowest month and set aside a tax reserve in a separate account.

State taxes and commission

States tax commissions as ordinary wages. In a state with no wage income tax, such as Texas or Florida, only federal tax and FICA apply. In states with flat or graduated rates, the extra state tax on commission can be another 3% to 10% of each commission check. Use the state field above, or open your state's calculator from the paycheck calculators by state hub. Some states also withhold commissions at a flat supplemental rate, such as California at 6.6%, which is again only a prepayment.

How to keep more of a commission check

• Maximize pre-tax benefits. A traditional 401(k), HSA and dependent care account reduce taxable income directly.
• Time large commissions. If your employer allows it, payment timing can shift income between years.
• Adjust your W-4. Increase or decrease withholding to match your real tax.
• Deduct legitimate expenses only where allowed. Unreimbursed employee expenses are generally not deductible for W-2 employees, but a self-employed salesperson may deduct business costs.
• Save for a bonus year. Commissions above the Social Security wage base of $184,500 stop Social Security tax for the rest of the year.

Commission take-home pay at different sales levels

These estimates assume a single filer with a $40,000 base salary, the 2026 standard deduction, no pre-tax deductions and no state income tax.

• $10,000 of commission: total pay $50,000, federal tax about $3,820 (the commission adds about $1,200), FICA $3,825, leaving about $42,355 a year or $1,629.04 per biweekly paycheck.
• $30,000 of commission: total pay $70,000, federal tax about $6,570 (the commission adds about $3,950), FICA $5,355, leaving about $58,075 a year or $2,233.65 per biweekly paycheck.
• $60,000 of commission: total pay $100,000, federal tax about $13,170 (the commission adds about $10,550), FICA $7,650, leaving about $79,180 a year or $3,045.38 per biweekly paycheck.
• $100,000 of commission: total pay $140,000, federal tax about $22,334 (the commission adds about $19,714), FICA $10,710, leaving about $106,956 a year or $4,113.69 per biweekly paycheck.

The list shows why commission checks feel smaller than expected: each extra dollar of commission is taxed at your marginal federal rate, which climbs from 12% to 22% and then 24%, and Social Security and Medicare take another 7.65% until the wage base is reached. Even so, higher commissions always leave you with more take-home pay.

Commission versus bonus: how the tax rules compare

Bonuses and commissions are both supplemental wages, so the same withholding choices apply, but commissions are usually earned steadily while bonuses arrive in lumps. A large bonus in one pay period can push that paycheck into a higher withholding bracket under the aggregate method, while commissions spread across the year rarely do. If you receive both, add them together in the calculator by entering the total as commission. For year-end bonus planning, use the bonus tax calculator.

Setting aside money and planning for irregular pay

People who earn mostly commission should build a buffer. A useful method is to base your budget on your lowest realistic month of net pay, put every above-average month into savings until you hold three to six months of expenses, and pay yourself a steady amount from that reserve. Track quarter-to-date commissions so that you know when your income may cross into the next bracket, and review your W-4 after a strong quarter. Our guide to building an emergency fund explains how to size the cushion, and the savings goal calculator shows how fast you can reach it.

Common mistakes with commission pay

• Assuming commissions are taxed at a higher rate. They are taxed at your marginal rate, and withholding is only an estimate.
• Spending gross commission. Plan with net pay.
• Ignoring state tax. A 5% state rate takes another $1,500 from $30,000.
• Not reserving for taxes as a contractor. Quarterly estimates are due.
• Forgetting clawbacks. Repaid commissions affect your W-2.

Key takeaways

• Commissions are ordinary wages subject to income tax and FICA.
• Employers may withhold a flat 22% federal rate or use the aggregate method.
• The flat rate can over- or under-withhold depending on your total income.
• Use the calculator to compare withholding with actual tax.
• Adjust your W-4 or make estimated payments if the gap is large.

The same example at different state tax rates

State income tax is the input that varies most between readers. Nine states charge 0% on wages, flat-tax states charge one rate, and progressive states charge more at higher incomes. Here is the example at five effective state rates; for your exact state rules, use the state paycheck calculators.

What changing annual commissions does

Holding everything else at the example values, here is the effect of annual commissions:

Commission checks and the Social Security wage base

High earners on commission often notice a sudden jump in take-home pay late in the year. That happens when year-to-date wages pass the $184,500 Social Security wage base for 2026: from then on, 6.2% stops coming out until January. A $20,000 commission paid after you pass the base keeps about $1,240 more than the same commission paid earlier in the year. If you budget around commission income, plan for the larger checks to shrink again in the new year.
