Bonus Tax Calculator
Compare what a bonus costs against the same money paid as tips or overtime premium — the 2026 deductions that rescue those two do nothing for a bonus.

What this result does not account for
- Assumes the percentage method; an employer who aggregates the bonus with regular wages withholds differently.
- The tips and overtime comparison prices classification only — a bonus cannot lawfully be relabelled.
- Models a single filer at 2026 thresholds with the standard deduction.
- State supplemental rates vary widely and several states use standard tables instead.
In short: A $15,000 bonus on a $115,000 salary costs $3,464.00 in federal income tax. The identical sum paid as qualified tips costs $0.00 and as overtime premium $550.00, because bonuses are excluded from the OBBBA deductions. Flat 22% withholding takes $3,300.00, leaving you $164.00 short.
Formula
A bonus is taxed at your marginal rate, which may straddle two brackets. The flat 22% supplemental rate is a withholding convention, not a tax rate, and rarely matches the liability exactly.
Worked Example
- Find the marginal cost. Adding $15,000 to a $115,000 salary pushes taxable income from $98,900 to $113,900, straddling the 22% and 24% brackets — $3,464.00 of tax.
- Price the same money as tips. Qualified tips of $15,000 are fully deductible under the $25,000 ceiling, so the income tax is $0.00.
- Price it as overtime premium. The overtime deduction caps at $12,500, leaving $2,500 taxable at 22% — $550.00.
- Compare the withholding. Flat 22% withholding takes $3,300.00 against a real liability of $3,464.00, so $164.00 is under-withheld and falls due at filing.
- Read the classification cost. The label on the payment is worth $3,464.00 here. Identical work, identical money, three different outcomes.
Most bonus calculators stop at the withholding illusion. The more consequential point in 2026 is that Congress carved out relief for tips and overtime and deliberately left bonuses, commissions and severance fully taxable. How compensation is classified now matters more than it has in decades.
Strengths & Limits Of This Model
Where this engine is strong
- Computes the true marginal cost across bracket boundaries rather than applying one flat rate.
- Prices what the 2026 tip and overtime deductions would have been worth, which bonuses cannot claim.
- Tracks the $1,000,000 supplemental threshold and the mandatory 37% above it.
Where it stops
- Cannot tell you whether work genuinely qualifies as tipped or FLSA overtime.
- Does not model deferred compensation timing or golden-parachute rules.
- Ignores local wage taxes, which several cities levy on supplemental pay.
Practical Use Cases
Negotiating how variable pay is structured
If genuine tipped or FLSA overtime work is involved, classification is worth real money. It cannot be relabelled after the fact.
Planning for the settlement at filing
Flat 22% withholding under-withholds whenever your marginal rate is higher. Set aside the difference rather than being surprised.
Deferring a bonus into a 401(k)
Deferral removes income tax but never FICA — the same asymmetry the W2 Tax Calculator traces through the wage boxes.
Modelling a very large bonus
Once supplemental wages pass $1,000,000 in a year, the excess is withheld at a mandatory 37% with no option to use the aggregate method.
Methodology & Editorial Standards
Real tax on the bonus is computed as the difference between total tax with and without it, which correctly captures a bonus that straddles brackets. Supplemental withholding follows IRS Publication 15 section 7: an optional flat 22% on supplemental wages up to $1,000,000 in a calendar year and a mandatory 37% above that, tracked using the year-to-date figure you supply. The comparison against tips and overtime applies the IRC 224 and 225 deductions to the same sum purely to price the classification difference — it is not a suggestion that a bonus can be recharacterised, which it cannot. Bonuses, commissions, severance and profit-sharing remain fully taxable ordinary income. The engine models a single filer at 2026 thresholds and assumes the employer uses the percentage method rather than aggregating the bonus with regular wages. The engine implements the standard published formula for this calculation. Inputs are validated for domain and sign before evaluation, and any undefined case returns an em-dash rather than a spurious value.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.

Bonus Tax Calculator — 20 Expert FAQs
20 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
Why is my bonus taxed at 22%?
It is not taxed at 22%, it is withheld at 22%. Your real liability here is $3,464.00 against $3,300.00 withheld, so you owe $164.00 more at filing.
Do bonuses qualify for the no tax on tips or overtime deductions?
No. Congress deliberately excluded them. The same $15,000 costs $3,464.00 as a bonus and $0.00 as qualified tips.
What is the bonus tax rate in 2026?
There is no separate bonus tax rate. Withholding is a flat 22% up to $1,000,000 of supplemental wages, then a mandatory 37%, but the tax is at your marginal rate.
Can I have less tax withheld from my bonus?
Not directly on a separate supplemental payment. You can adjust your regular W-4 or defer part of the bonus into a retirement plan.
Does deferring a bonus into my 401(k) avoid tax?
It defers income tax but never payroll tax. FICA applies to the full bonus whether you defer it or not.
What happens above $1,000,000 of bonuses?
The portion above $1,000,000 of supplemental wages in a calendar year must be withheld at 37%, with no option to use the aggregate method.
Is a signing bonus taxed differently?
No. Signing, retention, referral and performance bonuses are all supplemental wages and all fully taxable.
Why did my bonus push me into a higher bracket?
Only the portion above the threshold is taxed at the higher rate. Here $15,000 straddles the 22% and 24% bands, which is why 22% withholding falls short.
Do I pay Social Security on a bonus?
Yes, until your total wages reach the $184,500 wage base for 2026. Above that only Medicare continues.
Is severance treated like a bonus?
Yes. Severance is supplemental wages, fully taxable, and excluded from the tips and overtime deductions in the same way.
What is the aggregate withholding method?
The employer adds the bonus to your regular pay and withholds as though that were your normal earnings, which usually withholds more than the flat 22%.
Are commissions taxed like bonuses?
Yes. Commissions are supplemental wages subject to the same 22% flat withholding and the same exclusion from the new deductions.
Can my employer pay a bonus as tips instead?
No. Tips must be voluntary payments from customers. Recharacterising a bonus would be a misclassification, not tax planning.
Will my state tax the bonus too?
Almost certainly. Several states publish their own supplemental rate; others require the standard withholding tables.
Should I ask for a raise instead of a bonus?
For tax purposes they are identical — both are ordinary income. A raise compounds into future years and pension contributions, which a bonus does not.
Is this bonus tax calculator free to use?
Yes. It is free, requires no account, and has no usage limits. ApexConverter is funded by contextual advertising, never by selling user data.
Is my data sent to a server?
No. The engine runs as Vanilla JavaScript inside your browser under our Zero-Server Client-Side Execution model. Your figures are computed locally and are never transmitted, logged, or stored.
How accurate is this calculator?
It applies the standard closed-form formula in IEEE-754 double precision, rounding only at the display layer. The engine is reconciled against an independent reference implementation before release.
Does it work on mobile?
Yes. The interface is mobile-first with numeric keypad hints and is tested down to a 320-pixel viewport with no horizontal scrolling.
Can I use it offline?
Largely, yes. Because computation is client-side, the page continues to calculate without a network connection once it has loaded.
