Best 6 Bonus Tax Calculators in 2026: Compare Bonus Taxes

Introduction

TakeHomeIQ Paycheck Calculator is the strongest overall bonus tax calculator in this roundup. It estimates bonus withholding using both the flat-rate and aggregate methods. The six apps here range from paycheck estimators to tax-filing and sales-tax tools. Treat their results as guides, not final payroll calculations or tax advice.

Quick comparison

TakeHomeIQ is the only app here that clearly offers both common supplemental-pay withholding methods. Pay44 and My Paycheck Calculator are broader paycheck estimators that accept bonus income, too. TurboTax is for filing a return, while Tax Me and Tax Me Pro handle sales tax, not taxes on work bonuses.

1. TakeHomeIQ Paycheck Calculator

Best for: iPhone and iPad users comparing withholding methods for a bonus.

TakeHomeIQ Paycheck Calculator estimates take-home pay and supports supplemental pay through both flat-rate and aggregate methods. It breaks out estimated federal, state, FICA, and local taxes. The main advantage is being able to compare the two bonus withholding approaches in one place. Keep in mind that the result is an estimate, not a promise of what payroll will withhold.

2. Paycheck Calculator US - Pay44

Best for: Android users estimating a bonus alongside regular pay.

Paycheck Calculator US - Pay44 estimates take-home pay on U.S. earnings and accepts bonuses, commissions, overtime, and deductions. It also provides federal and state tax breakdowns. You can include several types of extra income in one paycheck estimate. The app information provided doesn’t say whether it offers separate flat-rate or aggregate bonus calculations.

3. My Paycheck Calculator

Best for: iOS users who want a broad paycheck breakdown that includes bonus income.

My Paycheck Calculator estimates after-tax paycheck income and supports bonuses, commissions, and other income sources. Its breakdown covers federal, state, and local taxes, FICA, and payroll deductions. Seeing these categories together can help you understand how an estimated bonus fits into your full paycheck. The listing doesn’t name a specific bonus withholding method.

4. TurboTax: File Your Tax Return

Best for: People finishing a tax return, not calculating bonus withholding.

TurboTax: File Your Tax Return can help people pick up an unfinished return or file after an extension deadline. Its listing also mentions connecting with an on-demand tax expert. Filing help across devices is a useful feature, but the listed tools don’t include a bonus-pay estimator. Use a paycheck calculator for withholding estimates.

5. Sales Tax Calculator - Tax Me

Best for: Calculating sales tax on purchases rather than taxes on a work bonus.

Sales Tax Calculator - Tax Me combines a sales-tax tool with a basic arithmetic calculator. According to its listing, you can save multiple tax rates, and the app is free. Saved rates can help with repeat purchase calculations, but this isn’t a bonus tax calculator. It doesn’t estimate income tax or withholding on bonus pay.

6. Tax Me Pro

Best for: Users who need sales-tax calculations and saved item lists.

Tax Me Pro offers a calculator, saved item lists, reverse tax calculation, and a companion Apple Watch app. Its reverse sales-tax feature is useful when you want to work backward from a price that already includes sales tax. The app doesn’t estimate bonus income tax or paycheck withholding, so it serves a different purpose from the paycheck calculators above.

How we picked these apps

Bonus-tax relevance came first. Apps that explicitly mention bonuses or supplemental pay are the closest match. We compared the methods and tax breakdowns described in each listing, without assuming an app has features that aren’t mentioned.

We included iOS and Android options where available. Paycheck estimators are listed separately from tax-filing services and sales-tax calculators, so it’s easier to see which tools fit your task. This roundup looks at each app’s stated features, not the accuracy of any individual tax result.

Frequently asked questions

Is a bonus taxed differently?

A bonus is generally treated as wage income, but payroll may calculate withholding differently from regular wages. Withholding is an estimate toward your tax bill; it doesn’t determine the final amount you owe.

What do flat-rate and aggregate methods mean?

With the flat-rate method, a set withholding rate is applied to supplemental pay. The aggregate method combines the bonus with regular wages for a pay period, then calculates withholding on the total. Estimates depend on the calculator’s inputs and assumptions.

What information affects a bonus estimate?

Pay frequency, location, deductions, and other income details can all affect an estimate. Your final pay stub may differ because payroll uses your actual records and the rules that apply to you. Sales-tax calculators don’t calculate income tax on bonuses. If the result could affect a filing decision, check current payroll details or talk with a qualified tax professional.

The verdict

TakeHomeIQ Paycheck Calculator is the strongest overall pick. It clearly compares flat-rate and aggregate bonus methods and shows several tax categories. For Android, Paycheck Calculator US - Pay44 is a useful runner-up for estimating bonuses alongside other pay and deductions. My Paycheck Calculator is another iOS option, with a broader breakdown. TurboTax, Tax Me, and Tax Me Pro are for different tasks, not bonus withholding.
