Bonuses paid to Tennessee workers are not taxed by the state at all, so the only money taken out before the bonus reaches your account is federal: a flat 22% for federal income tax on most bonuses, plus 6.2% for Social Security and 1.45% for Medicare. That works out to roughly 29.65% withheld up front. Whether that matches the tax you actually owe depends on your total income for the year, and any difference is settled when you file your return.
Tennessee Takes Nothing From Your Bonus
Tennessee has no individual income tax on wages, and that includes bonuses, commissions, and other supplemental pay.1Tennessee Department of Revenue. HIT-18 – Pension Income, Social Security, 401(k), and IRA Distributions The state used to collect the Hall Income Tax on interest and dividend income, but that tax was fully repealed effective January 1, 2021, and it never applied to wages or bonuses to begin with.2Tennessee Department of Revenue. HIT-3 – Hall Income Tax Repealed Beginning January 1, 2021 There is no city or county income tax layered on top either. Every dollar withheld from your bonus check is going to the federal government.
The Flat 22% Federal Withholding Rule
The IRS classifies bonuses as “supplemental wages,” along with commissions, severance, prizes, and other payments outside your regular salary. When your employer identifies the bonus separately from your normal paycheck, the standard practice is to withhold federal income tax at a flat 22%, regardless of your W-4 elections or your usual tax bracket.3Internal Revenue Service. Publication 15 (2026), (Circular E), Employers Tax Guide
That 22% applies to supplemental wages up to $1 million in a calendar year. Any supplemental pay above $1 million in a single year is withheld at 37%, the top federal rate, and your W-4 has no effect on that portion.3Internal Revenue Service. Publication 15 (2026), (Circular E), Employers Tax Guide
What a $5,000 Bonus Actually Looks Like
Here is the arithmetic on a typical $5,000 bonus for a Tennessee worker who has not yet reached the Social Security wage cap for the year:
- Federal income tax at 22%: $1,100
- Social Security at 6.2%: $310
- Medicare at 1.45%: $72.50
- Total withheld: $1,482.50
- Net deposit: $3,517.50
Those three federal items are the whole picture. A worker receiving the same $5,000 bonus in a state with a 5% income tax would see about $250 less in their account.
Why Some Bonuses Get Hit Harder: The Aggregate Method
Not every employer uses the flat 22%. Under the alternative aggregate method, the bonus is lumped in with your regular paycheck for that pay period, and withholding is calculated on the combined amount using the normal tax tables and your W-4.3Internal Revenue Service. Publication 15 (2026), (Circular E), Employers Tax Guide
This can push a single paycheck into a much higher withholding bracket. If you normally earn $3,000 biweekly and receive a $10,000 bonus in the same check, the payroll system withholds as though you earn $13,000 every two weeks, or $338,000 annualized. The effective rate on that paycheck can run well above 22%. You don’t choose which method your employer uses.
Higher withholding under this method is not a higher tax. It’s a bigger prepayment, and if too much came out, the excess returns to you as part of your refund when you file.
Social Security and Medicare on Your Bonus
Separate from income tax withholding, your bonus is also subject to FICA payroll taxes:
- Social Security takes 6.2%, but only up to the annual wage base limit. For 2026, that limit is $184,500 in combined wages and bonuses. Once you cross it, no further Social Security tax is withheld for the rest of the year.4Internal Revenue Service. Publication 15-A (2026), Employers Supplemental Tax Guide5Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet
- Medicare takes 1.45% with no cap. It applies to every dollar.4Internal Revenue Service. Publication 15-A (2026), Employers Supplemental Tax Guide
High earners pay an extra 0.9% Additional Medicare Tax on wages above $200,000 for single filers and $250,000 for married couples filing jointly. Your employer starts withholding the surtax once your year-to-date wages pass $200,000, regardless of filing status, and if your household stays under $250,000 jointly, you can reclaim the excess on your return.6Internal Revenue Service. Topic No. 560, Additional Medicare Tax
FICA taxes generally are not refundable through your return. The one common exception: if you worked for more than one employer and your combined wages exceeded the Social Security cap, the overpaid Social Security can be recovered when you file.
What You Actually Owe vs. What Was Withheld
The 22% is a withholding rate, not a final tax rate. When you file, the bonus is added to the rest of your income, and your total determines your real liability. The 2026 federal brackets for single filers are:7Internal Revenue Service. Tax Inflation Adjustments for Tax Year 2026
- 10% up to $12,400
- 12% from $12,401 to $50,400
- 22% from $50,401 to $105,700
- 24% from $105,701 to $201,775
- 32% from $201,776 to $256,225
- 35% from $256,226 to $640,600
- 37% above $640,600
These brackets apply to taxable income, meaning gross income minus the standard deduction ($16,100 for single filers and $32,200 for married couples filing jointly in 2026) and any other adjustments.7Internal Revenue Service. Tax Inflation Adjustments for Tax Year 2026 Only the slice of income inside each bracket is taxed at that bracket’s rate.
If your taxable income puts you in the 12% bracket, the 22% withheld from your bonus was more than you owed, and the extra comes back in your refund. If a large bonus pushes some of your income into the 24% or 32% bracket, you may owe a small balance when you file. The flat withholding is just an estimate; the return does the real math.
Ways to Reduce the Federal Bite
With no state tax to worry about, every strategy for lowering what you owe on a Tennessee bonus works on the federal side.
Route Part of the Bonus Into a 401(k)
Traditional 401(k) and 403(b) contributions reduce your taxable income dollar for dollar. For 2026, the elective deferral limit is $24,500. Workers age 50 and older can add $8,000 in catch-up contributions, and those aged 60 through 63 have an enhanced catch-up of $11,250.8Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 If your plan allows a bonus deferral election, you can send part or all of the bonus straight into the account before federal income tax is withheld.
Fund an HSA
If you are enrolled in a qualifying high-deductible health plan, HSA contributions are deductible as well. The 2026 limits are $4,400 for self-only coverage and $8,750 for family coverage.9Internal Revenue Service. Revenue Procedure 2025-19, 2026 HSA Inflation Adjusted Amounts Qualified medical withdrawals come out tax-free.
Adjust Your W-4
When you know a bonus is coming and the flat withholding is likely to miss the mark, submit a fresh W-4. Line 4(c) lets you request extra withholding each pay period, which can offset a shortfall before filing season. The IRS withholding estimator online is built for situations like this.
Keeping Clear of an Underpayment Penalty
A large bonus can leave your yearly withholding short. The IRS charges an underpayment penalty if you owe more than $1,000 at filing and haven’t met a safe harbor during the year. You stay safe by having total withholding and estimated payments cover at least 90% of your current-year tax, or 100% of last year’s tax, whichever is less.10Internal Revenue Service. Estimated Taxes
If a mid-year bonus leaves your withholding running low, you have two fixes. You can file a new W-4 to raise withholding from your remaining paychecks, or you can send a quarterly estimated payment to the IRS using Form 1040-ES. Either one counts toward the safe harbor and keeps the penalty off your return.
