How Commissions Are Taxed: W-2 vs 1099 Commission Pay

TLDR

Commissions are taxed as ordinary income, at the same bracket rates as your salary. There is no special commission tax rate. Say you are a W-2 employee. Then the IRS treats commissions as supplemental wages. Your employer may withhold a flat 22% federal income tax (37% on supplemental pay over $1 million in a year). That is only withholding, a prepayment. Your real tax is settled on your return. Say you are paid commissions on a 1099. Then nothing is withheld. You owe self-employment tax too. You usually need to make quarterly estimated payments.

A big commission check lands. You open the pay stub and a huge slice is gone. Or the opposite: you get paid on a 1099, nothing was taken out, and April feels a long way off.

Both cases come from the same mix-up. People think the amount taken out of a check is the tax rate on that money. It is not. Withholding is a down payment. The real bill is figured once, on your return, using your whole year of income.

This guide explains how commissions and taxes work for both kinds of earners. It covers why a commission check can look wrong, and how to fix it before year end.

Scope of this guide: federal income tax and payroll tax for tax year 2026, for W-2 employees and 1099 earners who are paid commissions. Texas has no state personal income tax, so a Texas resident has no state withholding on commission pay. If you live or work in another state, that state may have its own rules.

In this guide, you’ll learn:

Understand why commissions have no special tax rate, only special withholding rules
See the two ways your employer can withhold on a W-2 commission check
Learn why a commission check can look over-withheld or under-withheld
Know how 1099 commission pay is taxed, including self-employment tax
Get the steps to set quarterly payments or fix your W-4 before year end

#Commissions and taxes: the rate is the same, the withholding is not

#Commissions are ordinary income

On your return, a W-2 commission is just more wages. It shows up in Box 1 of your W-2 with your salary. A 1099 commission is business income. Either way, it is taxed at your ordinary income tax brackets, the same 10% to 37% ladder as everything else.

For example, the 2026 federal brackets for a single filer move from 22% to 24% at $105,700 of taxable income. They move to 32% at $201,775. A commission is taxed at whatever bracket your total income reaches. It is not taxed at a rate tied to the check.

#Why the check looks different

The difference is in withholding, the money your employer takes out and sends to the IRS for you. The IRS has special withholding rules for pay that is not regular salary. Those rules can make a commission check look very different from a normal paycheck. The tax on your return will be the same either way.

#How W-2 commissions are withheld: the supplemental wage rules

#Commissions are “supplemental wages”

IRS Publication 15 (2026), section 7, says supplemental wages are pay that is not regular wages. It lists bonuses, commissions, and overtime pay among them. The Treasury rule behind it is 26 CFR §31.3402(g)-1. It says pay that changes from period to period, like commissions, is not regular wages.

#Method 1: the flat 22%

Per Pub 15, section 7: say your employer pays the commission separately from your salary. Or it lists the two amounts separately on one check. Either way, say it withheld income tax from your regular pay this year or last year. Then it may withhold a flat 22% federal income tax on the commission. The employer chooses this. It is optional for supplemental pay up to $1 million.

Pub 15’s “What’s New” section confirms the 22% rate stays in place for 2026. That’s because the One Big Beautiful Bill Act made the current tax rates permanent.

#Method 2: the aggregate method

The other option is to add the commission to a regular paycheck and figure withholding on the total. The whole amount is treated as if it were your normal pay for that period. The withholding tables in Publication 15-T work by multiplying one check by the number of pay periods in a year. That gives a yearly figure. So a large combined check is treated, for that one check, as if you earned that much every period.

#Over $1 million: a mandatory 37%

Once an employee’s supplemental pay passes $1 million in a year, the excess must be withheld at 37%. This counts related companies under common control. It does not matter what your Form W-4 says. This one is not optional.

#Payroll taxes still apply

Whatever method is used for income tax, Pub 15 says supplemental wages are still subject to Social Security and Medicare tax. Your share is 6.2% for Social Security (up to the $184,500 wage base for 2026) and 1.45% for Medicare. Your employer also must withhold an extra 0.9% Additional Medicare Tax on your wages above $200,000 for the year, per Pub 15.

#A worked example: a $10,000 commission at the flat rate

Say you are a W-2 salesperson and your employer pays a $10,000 commission as a separate check using the flat 22% method. You are under the Social Security wage base for the year.

Federal income tax withheld, 22% of $10,000: $2,200
Social Security, 6.2% of $10,000: $620
Medicare, 1.45% of $10,000: $145
Total withheld: $2,200 + $620 + $145 = $2,965
Net check: $10,000 minus $2,965 = $7,035

Texas has no state income tax, so for a Texas resident there is no state line on this check.

#Why your commission check looks over- or under-withheld

The withholding method does not know your full year. That is why the check can look wrong in either direction.

Flat 22% withholding vs your real bracket (illustrative)
	Your situation	What 22% does
Your top bracket is 10% or 12%	Withholds more than your real rate on that money	Likely refund of the extra
Your top bracket is 22%	Close to your real rate	Roughly even
Your top bracket is 24% or higher	Withholds less than your real rate	Likely balance due

#When it looks over-withheld

Say your total income keeps you in the 10% or 12% bracket. Then a flat 22% takes out more than the tax you will really owe on that commission. The extra comes back as part of your refund. The aggregate method can also over-withhold on a single big check. It treats that check as if it were your normal pay every period.

#When it is under-withheld

If you are a high earner, 22% can be too little. For a single filer, everything above $201,775 of taxable income is taxed at 32% or more in 2026. A top salesperson with large commissions can owe a balance in April even though tax was taken from every check. This is the case to watch.

#How to fix it before year end

Update your Form W-4. Step 4(c) lets you ask for extra withholding from every paycheck.
Run the IRS Tax Withholding Estimator after a big commission to see if you are on track.
Make an estimated payment if you are short. You can pay the IRS directly, not just through payroll.

#How 1099 commissions are taxed

If you get a 1099 for your commissions, you are paid as an independent contractor, not an employee. Nothing is withheld. You handle all of it.

#Some commission earners are self-employed by law

Not every commission earner can choose. Pub 15, section 2, says qualified real estate agents and direct sellers are statutory nonemployees if three things are true. They are licensed (for real estate agents). Almost all their pay comes from sales, not hours. A written contract says they are not employees. If you are not sure which group you fall in, our guide to 1099 vs W-2 classification explains the tests.

#You owe self-employment tax

A 1099 earner pays both halves of Social Security and Medicare as self-employment tax. The rate is 15.3% on 92.35% of your net profit, with the Social Security part stopping at the $184,500 wage base for 2026. You also get to deduct half of it when figuring your adjusted gross income, per the IRS self-employment tax page.

Example: you earn $60,000 of net profit from 1099 commissions in 2026, after business expenses.

Net earnings for SE tax: $60,000 × 92.35% = $55,410
SE tax: $55,410 × 15.3% = $8,477.73, about $8,478
Half of that, about $4,239, is deducted from your income for income tax

That $8,478 is on top of your regular income tax. This is the part that surprises new 1099 earners the most.

#You deduct business expenses

The upside of a 1099 is that you report the income on Schedule C and subtract real business costs first: mileage, phone, software, marketing, licensing fees. Keep records as you go. Our guide to business mileage records shows what the IRS expects for the biggest one.

#Quarterly estimates for 1099 commission earners

#Who has to pay estimates

Per IRS Publication 505, you generally must pay estimated tax for 2026 if two things are true. You expect to owe at least $1,000 after withholding and credits. And your withholding and credits will be less than the smaller of:

90% of the tax on your 2026 return, or
100% of the tax on your 2025 return (110% if your 2025 adjusted gross income was over $150,000, or $75,000 if married filing separately)

Our guide to estimated tax safe harbor rules walks through these tests.

#The 2026 due dates

Payments for tax year 2026 are due April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027. If a date lands on a weekend or holiday, the payment is on time the next business day. You can skip the January payment if you file your 2026 return and pay in full by February 1, 2027.

#Lumpy commissions and the annualized method

Commission income often comes in bursts. Pub 505 describes the annualized income installment method. It lets your required payments follow when you actually earned the money, instead of four equal amounts. Our guide to quarterly estimates done right shows how to set payments from a real projection.

#When an S-corp enters the picture

If your 1099 commission profit grows, an S-corp election can change how much of it is hit by self-employment tax. It also adds payroll and a separate return. See when an S-corp election starts to make sense before you decide.

#How Elevated can help

We help commission earners set up a tax plan that matches how they are paid: checking W-4 withholding after big checks, or setting quarterly estimates for 1099 income from a real projection. For 1099 earners, clean monthly bookkeeping keeps your expenses ready for the return.

#Common questions

#Are commissions taxed at a higher rate than salary?

No. Commissions are taxed at the same bracket rates as salary. They may be withheld at a flat 22%. That can feel higher. But the real tax is figured on your return, using your whole year.

#Why was so much taken out of my commission check?

Your employer may have added the commission to your regular pay and withheld as if you earned that much every pay period. Or it used the flat 22% and your real bracket is lower. Any extra comes back when you file.

#Is the 22% supplemental rate my final tax?

No. It is only withholding. If your bracket is lower, you get the extra back. If it is higher, you owe more when you file.

#Can I ask my employer to withhold more from my commissions?

You can add extra withholding on Form W-4, Step 4(c). It applies to your paychecks. Whether it applies to a separate commission check paid at the flat rate depends on how your employer runs payroll. Ask your payroll team.

Yes. W-2 commissions are subject to Social Security and Medicare like any wages. 1099 commissions are subject to self-employment tax, which covers both halves.

#I get commissions on a 1099. Do I have to pay quarterly?

Usually yes, if you expect to owe at least $1,000 for the year after withholding and credits. If you also have a W-2 job, raising your W-4 withholding there can cover some or all of it.

#Are real estate commissions taxed differently?

Qualified real estate agents are treated as self-employed by law, so their commissions are 1099 income with self-employment tax. The income tax brackets are the same as for anyone else.

#How do I report a 1099 commission?

On Schedule C, as business income, with your business expenses subtracted. Then the profit flows to Schedule SE for self-employment tax. Check your IRS wage and income transcript to make sure every 1099 is counted.

#Ready to talk through your situation?

The right withholding or quarterly amount depends on your full year, not one check. The easiest way to get it right is to look at your numbers together.
