2026 Tax Bracket Calculator — Federal Tax Brackets & Marginal Rate

A tax bracket calculator shows exactly how much of your income falls into each of the seven federal tax brackets, and how much tax you owe in each one. The most common misunderstanding about taxes is thinking a raise that pushes you "into a higher bracket" means all of your income gets taxed at that higher rate — it does not. The US uses a marginal tax system, where only the income above each bracket threshold is taxed at that bracket's rate. This calculator visualizes that breakdown so the difference between your marginal rate (the rate on your last dollar earned) and your effective rate (the rate on your total income) becomes concrete rather than abstract.

How to use this Tax Bracket Calculator

1. 1Enter your annual income — gross income before any deductions.
2. 2Select your filing status: Single or Married Filing Jointly.
3. 3The calculator subtracts the standard deduction ($16,100 single / $32,200 married for 2026) to find your taxable income.
4. 4Read the bracket-by-bracket breakdown showing exactly how much of your income is taxed at each of the seven rates.
5. 5Compare your marginal rate (the rate on your next dollar earned) against your effective rate (your actual overall tax rate) — they are usually very different numbers.

Progressive tax bracket formula explained

Federal income tax is calculated progressively: income is sliced into segments matching each bracket's range, and each segment is taxed only at that bracket's rate. The total tax owed is the sum of the tax owed in every bracket your taxable income passes through. Your marginal rate is the rate of the highest bracket you reach; your effective rate is total tax divided by total income, which is always lower than your marginal rate because the earlier, lower-taxed brackets pull the average down.

Calculate tax brackets: $85,000 income, single filer, 2026 brackets

1. 01Gross income: $85,000. Standard deduction (single, 2026): $16,100.
2. 02Taxable income: $85,000 − $16,100 = $68,900.
3. 0310% bracket ($0–$12,400): $12,400 taxed at 10% = $1,240.
4. 0412% bracket ($12,400–$50,400): $38,000 taxed at 12% = $4,560.
5. 0522% bracket ($50,400–$68,900): $18,500 taxed at 22% = $4,070.
6. 06Total tax: $1,240 + $4,560 + $4,070 = $9,870.

Tips and things to know

• ✓Never confuse your marginal rate with your effective rate when estimating your actual tax burden — effective rate is always the more accurate number for budgeting purposes.
• ✓Pre-tax retirement contributions (401k, traditional IRA) reduce taxable income directly, which can be especially valuable if they keep you out of a higher marginal bracket.
• ✓If you are close to a bracket threshold near year-end, additional pre-tax contributions or deductible expenses can meaningfully reduce the tax owed on income in the higher bracket.
• ✓A bonus or one-time payment that looks like it is "taxed at 35%" is often actually withheld at a flat supplemental rate for convenience — your actual tax owed is still calculated using the full progressive bracket system at filing time.
• ✓Use this calculator alongside the Paycheck Calculator to see both your bracket breakdown and your actual per-paycheck take-home pay after all deductions.

Tax Bracket Calculator — bottom line

The single most important thing to understand about US income taxes is that marginal rates are not applied to your entire income. The progressive bracket system means the first $12,400 of taxable income is taxed at 10%, the next tranche at 12%, and so on — only the portion of income above each threshold is taxed at the higher rate. A single filer with $100,000 in taxable income who is "in the 22% bracket" actually pays 10% on the first $12,400, 12% on the next $38,000, and 22% on the remaining $49,600 — an effective rate of roughly 16.7%, not 22%. The most common misconception — that a raise can put you in a higher bracket and reduce your take-home pay — is false. Only the dollars above the threshold are taxed at the higher rate. A $1 raise always produces more than $1 in take-home pay. Second: marginal brackets create powerful math for pre-tax deductions. If you are in the 22% bracket, a $1,000 pre-tax 401(k) contribution saves $220 in federal tax immediately. A $1,000 deduction in the 24% bracket saves $240. The higher your bracket, the more valuable each dollar of deductible contribution or expense — this is why maxing out pre-tax retirement accounts makes more mathematical sense at high incomes than at low incomes. Third: tax bracket thresholds are adjusted for inflation each year, so prior-year numbers become outdated quickly. Always use a current-year source when making planning decisions, and combine this calculator with the Income Tax Calculator to see both your bracket distribution and your total estimated tax for the current filing year.
