Quick Answer
Commission pay is earnings based on sales performance, typically calculated as a percentage of sales (2-10%) or flat fee per sale. Your employer withholds taxes from commission payments at a flat 22% federal rate for amounts under $1 million, which may result in over- or under-withholding compared to your regular tax bracket.

Best for anyone receiving commission as part of their W-2 employment, whether as a sales rep, real estate agent, or other commissioned role
How commission pay is calculated and paid
Commission pay rewards you for performance, typically sales results. Most commission structures fall into these categories:
Example: $60,000 salary plus 5% commission
Let's say you're a sales rep earning $60,000 base salary plus 5% commission on sales:
Your employer must withhold taxes on the full $7,500, but commission payments are withheld differently than regular wages.
How commission withholding works
According to IRS Publication 15-T, employers withhold federal taxes on commission payments using either:
1. Aggregate method: Combine commission with regular wages, calculate withholding on total
2. Flat rate method: Withhold at flat 22% rate on commission portion only
Most employers use the 22% flat rate because it's simpler. This means:
Key factors that affect commission pay
What you should do
1. Track your commission income separately for budgeting purposes
2. Adjust your W-4 if you're consistently over- or under-withheld on commission
3. Set aside extra tax savings if you're in a higher bracket than 22%
4. Use our paycheck calculator to estimate your take-home pay including commission
Key takeaway: Commission is taxed as regular income but withheld at a flat 22% rate, which may not match your actual tax bracket. Track commission separately and adjust withholding accordingly.
