Quick Answer
COMMISSION or COMM on your pay stub represents sales-based income you earned during that pay period. It's taxed as regular income with the same federal, state, FICA, and other withholdings as your base salary. For example, a $5,000 commission gets roughly $1,800 withheld for taxes (36% effective rate for most earners).

What commission means on your pay stub
COMMISSION or COMM represents sales-based income you earned during that specific pay period. Unlike your regular salary that's paid consistently, commission varies based on your sales performance, deals closed, or revenue generated.
Commission income is treated exactly like regular wages for tax purposes. It's subject to federal income tax withholding, state income tax (where applicable), Social Security tax (6.2%), Medicare tax (1.45%), and any other deductions like health insurance or 401(k) contributions.
Example: $3,000 commission on your pay stub
Let's say you earned a $3,000 commission that appears on your biweekly pay stub. Here's how the taxes typically break down:
Your employer might also deduct health insurance premiums, 401(k) contributions, or other benefits from your commission, just like they do with regular wages.
How commission withholding works
Employers typically use one of two methods for commission withholding:
1. Aggregate method: Your commission is added to your regular pay, and taxes are withheld based on your total earnings for that period
2. Flat rate method: Commission is taxed at a flat 22% federal rate (for amounts up to $1 million), plus FICA taxes
The flat rate method often results in over-withholding, which means you'll get a larger refund when you file your tax return.
Key factors that affect commission taxation
What you should do
If you receive significant commission income, consider adjusting your W-4 withholding to account for the variable nature of your earnings. Large commission checks often have taxes over-withheld, while small ones might be under-withheld.

Commission considerations for high earners
As a high earner, your commission income faces additional tax complexities that can significantly impact your take-home pay and year-end tax situation.
Higher marginal tax rates: If your total income (salary + commission) exceeds $197,300 (single) or $394,600 (married filing jointly), your commission gets taxed at the 32% federal bracket, plus state taxes that can reach 13.3% in California.
Additional Medicare tax: Commission income over $200,000 (single) or $250,000 (married) triggers an additional 0.9% Medicare tax. This often isn't withheld properly, leading to underpayment penalties.
Example: $25,000 annual bonus/commission
For a high earner receiving a large commission payment:
Strategic considerations
Timing matters: If possible, consider the timing of commission payments. Receiving large commissions in different tax years can help manage your tax bracket.
Estimated payments: High commission earners often need to make quarterly estimated tax payments to avoid underpayment penalties, especially if commission represents a large portion of total income.
Retirement planning: Maximize 401(k) contributions in high-commission years. The 2026 limit is $23,500 (or $31,000 if 50+), which can significantly reduce your taxable commission income.
Key takeaway: High earners can see 45-50% effective tax rates on commission income when including federal, state, FICA, and additional Medicare taxes.
Key Takeaway: High earners face 45-50% effective tax rates on commission income and should consider timing strategies and increased retirement contributions.
