Federal Income Tax Calculator
Federal income tax for 2026 depends on filing status and taxable income because progressive rates apply one band at a time. This calculator estimates federal income tax, credits, self-employment tax, and a refund or balance from the facts entered; it does not complete a return or resolve income, deduction, credit, and filing-status issues outside its modeled inputs.
Wondering if you'll owe taxes this year or get money back? You're not alone — the average American spends 13 hours preparing their taxes, often unsure if they're doing it right. This calculator uses the 2025 and 2026 tax brackets (pick the year below) to give you a clear picture, so there are no surprises come April.
How much federal income tax will I owe in 2025 or 2026?
Your 2026 federal income tax depends on your taxable income and filing status. The US uses 7 progressive tax brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%). Only income within each bracket is taxed at that rate — not your entire income.
- 2026 standard deduction: $16,100 (single), $32,200 (married filing jointly)
- 2026 10% bracket: $0-$12,400 (single), $0-$24,800 (MFJ)
- 2026 top 37% bracket: over $640,600 (single), over $768,700 (MFJ)
- Child Tax Credit: Up to $2,200 per qualifying child under OBBB
The federal tax system isn't 'one rate' — it's a staircase. You climb bracket by bracket, and only the dollars on each step pay that step's rate. The number that scares people (24%, 32%, 35%) is almost never what they actually owe overall. Effective rate is usually a lot lower than marginal.
Real-world scenario
A single filer, $92,000 gross, standard deduction
Take a single filer earning $92,000 with the 2025 standard deduction ($15,750). Taxable income drops to $76,250. Federal tax: about $11,765. That's a 22% marginal bracket but only a 12.8% effective rate on gross income. The next dollar earned is taxed at 22 — the average dollar earned was taxed at 12.8.
The part most people miss
Marginal vs effective is the single most misunderstood concept in U.S. tax. Crossing into the 24% bracket does NOT mean your whole salary suddenly gets taxed at 24%. Only the dollars above the bracket threshold do, so bracket math alone never turns a raise into a loss. Credits are different: the Child Tax Credit drops $50 for each $1,000 or part of $1,000 over its phaseout threshold, so a married couple with two kids who go from $400,000 to $400,002 of AGI lose $50 of credit on a $2 raise.
Meet Sarah
"Last year, Sarah nearly overpaid by $2,400 because she didn't realize she could deduct her student loan interest and HSA contributions. She came to us in March, and we helped her catch those deductions before filing. Don't let that be you."

Your filing status affects your tax brackets and standard deduction — it's worth getting right.

Your Earnings This Year
Include all income sources — the IRS sees them all anyway, so it's better to know now.
Collectibles (28%), unrecaptured Section 1250 gain (up to 25%) and Section 1202 stock need the Schedule D Tax Worksheet; use the Capital Gains or Depreciation Recapture calculator for those.
