2026 Tax Bracket Calculator

What this computes

The single most persistent misunderstanding in personal finance is how tax brackets work. People say "I'm in the 22% bracket" and quietly assume 22 cents of every dollar they earn goes to the IRS. It doesn't. The bracket system taxes income in slices: your first dollars fill the cheapest bracket, the next dollars fill the next one, and only the top slice of your income is taxed at your top rate.

This calculator runs the actual piecewise math for tax year 2026 (returns filed in early 2027), using the bracket thresholds and standard deduction the IRS announced in Rev. Proc. 2025-32 on October 9, 2025. You enter gross income and a filing status; it returns taxable income, total federal tax, your marginal rate, your effective rate, after-tax income, and a table showing how many dollars were taxed at each of the seven rates.

The scope is deliberately narrow: federal income tax only. No state or local income tax, no FICA (Social Security and Medicare payroll tax), no tax credits, no capital gains rates. Those all matter to your real bottom line — the limits section covers what is left out and why — but keeping the model to one tax makes the bracket mechanics visible instead of burying them.

The 2026 federal tax brackets

Rates apply to taxable income — gross income minus your deduction — not to gross income. For tax year 2026 the standard deduction is $16,100 for Single filers and $32,200 for married filing jointly. The seven rates are permanent under the One Big Beautiful Bill Act (2025); the dollar thresholds below adjust for inflation each year.

Single filers, tax year 2026

Married filing jointly, tax year 2026

The "tax at top of bracket" column is the cumulative tax owed if your taxable income exactly fills the bracket. It is also how the IRS expresses the schedule: a Single filer with $100,000 of taxable income owes $5,800 plus 22% of the amount over $50,400 — $5,800 + $10,912 = $16,712.

The math

Taxable income     = max(0, Gross income − Deduction)
Federal tax        = Σ over brackets:
                     (dollars of taxable income in bracket) × (bracket rate)
Marginal rate      = rate of the bracket your next dollar falls into
Effective (gross)  = Federal tax / Gross income
Effective (taxable)= Federal tax / Taxable income
After-tax income   = Gross income − Federal tax

A worked example

A Single filer grosses $85,000 in 2026 and takes the standard deduction of $16,100. Taxable income is $85,000 − $16,100 = $68,900. That fills the brackets from the bottom up:

• First $12,400 × 10% = $1,240
• Next $38,000 (from $12,400 to $50,400) × 12% = $4,560
• Last $18,500 (from $50,400 to $68,900) × 22% = $4,070
• Total federal tax: $1,240 + $4,560 + $4,070 = $9,870
• Marginal rate: 22% (the next dollar lands in the 22% bracket)
• Effective rate on gross: $9,870 / $85,000 = 11.6%
• Effective rate on taxable: $9,870 / $68,900 = 14.3%
• After-tax income (federal only): $85,000 − $9,870 = $75,130

Notice the gap: this filer is "in the 22% bracket" but actually pays 11.6 cents of federal tax per gross dollar. Only $18,500 of the $85,000 — about a fifth — ever sees the 22% rate. The deduction, the 10% slice, and the 12% slice shield everything else.

Your bracket is the rate on your next dollar, not the rate on every dollar.

The "raise pushed me into a higher bracket" myth

Every year someone turns down overtime, a raise, or a bonus because they believe crossing a bracket line will cost them money. The arithmetic says otherwise, and it is worth seeing once with real numbers.

Take a Single filer grossing $66,500 in 2026 with the standard deduction. Taxable income is exactly $50,400 — the precise top of the 12% bracket — and the federal tax is $1,240 + $4,560 = $5,800. Now give them a $1,000 raise, to $67,500 gross. Taxable income becomes $51,400, which crosses into the 22% bracket. What happens?

• The first $12,400 of taxable income is still taxed at 10%: $1,240
• The next $38,000 is still taxed at 12%: $4,560
• Only the new $1,000 is taxed at 22%: $220
• New total: $6,020 — the raise cost $220 in tax and added $780 of after-tax income

Nothing that was previously taxed at 10% or 12% got re-taxed at 22%. The filer's marginal rate jumped from 12% to 22%, but their effective rate on gross moved only from 8.7% to 8.9%. Under the bracket system, more gross income always means more after-tax income. The one real caveat lives outside the brackets: benefit cliffs. Some credits and subsidies (ACA premium credits, certain state programs) cut off sharply at income thresholds, and crossing one of those can genuinely cost more than the raise. That is a program-design problem, not a bracket problem.

We unpack this distinction — and when each rate is the right one to use for a decision — in the companion guide on marginal vs effective tax rates.

How to use this

1. Start with last year's gross income. Wages, freelance profit, interest — the pre-deduction total. The calculator applies the 2026 standard deduction for your filing status automatically.
2. Check the marginal rate before a money decision. A raise, a bonus, extra freelance work, or a Roth conversion is taxed at the margin. If you are at $68,900 taxable as a Single filer, every additional dollar up to $105,700 costs 22 cents of federal tax.
3. Use the effective rate for budgeting. Total federal tax divided by gross is what actually leaves your paycheck over the year. It is the honest input for a savings plan, not the bracket number.
4. Model pre-tax contributions with the custom deduction. Enter the standard deduction plus a planned 401(k) or traditional IRA contribution to approximate how the contribution shrinks taxable income. A $10,000 contribution at a 22% marginal rate avoids about $2,200 of federal tax this year.
5. Compare filing statuses if you are getting married. The MFJ brackets are exactly double the Single brackets through the 32% rate; only the 35% and 37% thresholds break the doubling, which is where the so-called marriage penalty for two high earners comes from.

What this calculator doesn't model

• State and local income tax. Anywhere from 0% (Texas, Florida, Washington and others) to over 13% at the top in California. Your combined marginal rate can be far above the federal number shown here.
• FICA. Employees pay 6.2% Social Security (up to the annual wage base) plus 1.45% Medicare on wages; the self-employed pay both halves. FICA is a flat-ish tax on wages that exists entirely outside the bracket system.
• Credits. The child tax credit, earned income credit, education credits, and others reduce the tax bill after the bracket math, sometimes to zero or below. A household with children will usually owe less than this calculator shows.
• Capital gains and qualified dividends. Long-term gains use a separate 0% / 15% / 20% rate schedule. This tool treats all income as ordinary.
• Other filing statuses and edge taxes. Head of household and married filing separately have their own thresholds; high earners can face the additional Medicare tax, net investment income tax, or AMT. None are modeled.
• Withholding. The output is your annual liability, not what each paycheck deducts. If withholding runs ahead of liability you get a refund; behind, you owe in April.
