How Bonuses Are Taxed in Utah in 2025
Your bonus gets taxed in two ways in Utah. First, you pay federal taxes on it. Then you pay Utah state taxes too.
The federal government treats bonuses as supplemental income. That’s just a fancy way of saying “extra money.” Your boss takes out 22% for federal taxes when you get a bonus. This happens if your bonus comes in a separate check.
But here’s the thing – if your total bonuses for the year are over $1 million, you pay 37% federal tax on the amount over $1 million.
Utah doesn’t care if it’s bonus money or regular pay. The state treats all your income the same way. So your bonus gets taxed at Utah’s flat rate just like your regular paycheck.
You also pay Social Security tax (6.2%) and Medicare tax (1.45%) on bonus money. These are the same rates you pay on regular wages.
When tax time comes, you might get some money back. The 22% federal withholding is often more than you actually owe. It depends on your total income for the year.
Utah Bonus Tax Rate 2025
Utah has a flat income tax rate of 4.50% for 2025. This rate applies to all your income, including bonuses.
Here’s what gets taken from your Utah bonus:
• Federal taxes: 22% (or 37% if over $1 million total bonuses) • Utah state tax: 4.50% • Social Security: 6.2% • Medicare: 1.45%
So if you get a $1,000 bonus, here’s what comes out: • Federal: $220 • Utah: $45 • Social Security: $62 • Medicare: $14.50 • Total taxes: $341.50 • You keep: $658.50
Utah’s rate dropped from 4.55% to 4.50% starting June 1, 2025. This small change saves you $0.50 for every $1,000 in bonus money.
Remember, Utah doesn’t have separate rules for bonus pay. Your employer uses the same 4.50% rate whether it’s your regular pay or bonus money. This makes things simple compared to other states.
The actual amount you owe might be different when you file your tax return. It depends on your total income and deductions for the year.

Regular Pay vs. Bonus Tax Comparison
| Tax Type | Regular Pay Rate | Bonus Rate | Why It’s Different |
|---|---|---|---|
| Federal | Your tax bracket (10-37%) | 22% flat rate | Bonuses use special withholding |
| Utah State | 4.5% flat rate | 4.5% flat rate | Same rate for both |
| Social Security | 6.2% | 6.2% | Same rate for both |
| Medicare | 1.45% | 1.45% | Same rate for both |
The big difference is federal taxes. Your regular pay uses your normal tax bracket. But bonuses get hit with that flat 22% rate right away.
2025 Utah Tax Changes
Good news for Utah workers! The state dropped its income tax rate for 2025:
- Old rate: 4.55% (2024)
- New rate: 4.5% (2025)
- Savings: You keep 0.05% more of your bonus
This small change saves you $5 for every $10,000 in bonus money. It’s not huge, but every dollar counts.
Utah still uses a flat tax rate. This means everyone pays the same 4.5% rate. It doesn’t matter if you make $30,000 or $300,000 per year.
