Two Methods of Bonus Withholding

Method 1: Percentage Method (Most Common)

Flat 22% federal withholding on bonuses:

Bonus 22% Withheld
$5,000 $1,100
$10,000 $2,200
$25,000 $5,500

Used by most employers because it’s simple.

Method 2: Aggregate Method

Bonus combined with regular paycheck, taxed at regular marginal rate:

Example Without Bonus With Bonus
Paycheck $4,000 $4,000
Bonus $10,000
Total $4,000 $14,000
Withholding $600 $2,800
Bonus portion ~$2,200

May result in higher or lower withholding depending on your tax bracket.

High-Income Bonus Withholding

For bonuses over $1 million in a year:

Portion Federal Rate
First $1 million 22%
Above $1 million 37%

Example: $1.5 Million Bonus

Portion Amount Rate Tax
First $1M $1,000,000 22% $220,000
Above $1M $500,000 37% $185,000
Total $1,500,000 $405,000

Plus FICA (up to wage base) and state taxes.

Social Security Wage Base Impact

Social Security tax (6.2%) stops after you earn $176,100 (2026):

Scenario SS Tax on Bonus
YTD earnings < $176,100 Full 6.2%
YTD earnings at $176,100 0%
YTD earnings near limit Partial

Example

Situation Bonus SS Tax
Earned $100k, get $10k bonus $620 (full)
Earned $170k, get $10k bonus $378 (partial)
Earned $180k, get $10k bonus $0

Year-end bonuses may have lower FICA if you’ve maxed out Social Security.

Key concept: Withholding ≠ actual tax owed

Reality Explanation

Lower brackets May get refund (22% > actual rate)
Higher brackets May owe more (22% < actual rate)

Tax Bracket Reality Check

If Your Marginal Rate Is 22% Withholding Is
10% Overwithholding → refund
12% Overwithholding → refund
22% About right
24% Underwithholding → owe
32% Underwithholding → owe
35%+ Significant underwithholding
