2026 Federal Income Tax Brackets Explained (All Filing Statuses)

Every January the IRS releases updated federal income tax brackets, and the 2026 federal tax brackets — set under IRS Rev. Proc. 2025-32 — are what your employer's withholding and your tax return will use for the 2026 tax year. The brackets are inflation-adjusted each year, so the thresholds creep upward and slightly more of your income lands in the lower-rate bands.

Understanding the brackets is essential to reading your own payslip and estimating your take-home pay, because federal income tax is the single largest deduction for most US workers. This guide lays out all four filing statuses, the 2026 standard deduction, and how the marginal system actually applies to your salary.

How Federal Tax Brackets Work

The biggest misconception about US income tax is that you pay your top rate on everything you earn. That's not how it works. The US uses a progressive, marginal system: your income is sliced into bands, and each slice is taxed at the rate for the band it falls into. Only the portion of income that spills into a higher bracket is taxed at that higher rate.

So if you're a single filer whose taxable income reaches the 22% bracket, you don't pay 22% on all of it. You pay 10% on the first slice, 12% on the next slice, and 22% only on the portion that actually sits in that top band. This is why a "raise into a higher bracket" never leaves you with less take-home pay — only the dollars above the threshold are taxed at the higher rate.

It's also why how do tax brackets work is one of the most searched tax questions: the intuition feels wrong until you see a worked example, which we'll walk through below.

2026 Federal Income Tax Brackets

These are the 2026 federal income tax brackets by filing status. All thresholds apply to taxable income — that is, your income after the standard deduction (and any other adjustments) has been subtracted. A salary that sounds like it lands in the 24% bracket may, after the deduction, actually fall in the 22% band.

The 2026 Standard Deduction

The 2026 standard deduction is the amount the IRS lets you subtract from your gross income before the brackets apply. Most people take the standard deduction rather than itemising, since the Tax Cuts and Jobs Act roughly doubled it and capped key itemisable deductions.

Putting it simply: taxable income = gross income − standard deduction (ignoring other adjustments like pre-tax 401(k) contributions for this illustration). That taxable income is the number you carry into the bracket tables above.

Marginal vs Effective Tax Rate

Your marginal tax rate is the rate applied to your last, topmost dollar of taxable income — the rate of the highest bracket your income reaches. It's the number people usually mean when they say "I'm in the 22% bracket."

Your effective tax rate is your total federal income tax divided by your income. Because the lower portions of your income are taxed at 10% and 12%, your effective rate is always lower than your marginal rate — often considerably so.

The marginal vs effective tax rate distinction matters for planning: your marginal rate tells you the tax cost of earning one more dollar (useful for decisions about overtime, side income, or a raise), while your effective rate tells you the real average bite tax took out of your paycheck.

Worked Example: $100,000 Single Filer

Let's apply the 2026 federal tax brackets single table to a $100,000 salary for a single filer taking the standard deduction.

Step 1 — Calculate taxable income

• Gross salary: $100,000
• Minus 2026 standard deduction (single): $16,100
• Taxable income: $100,000 − $16,100 = $83,900

Step 2 — Apply the brackets slice by slice

• 10% on the first $12,400 = $1,240
• 12% on ($50,400 − $12,400) = 12% × $38,000 = $4,560
• 22% on ($83,900 − $50,400) = 22% × $33,500 = $7,370
• Total federal income tax: $1,240 + $4,560 + $7,370 = $13,170

Marginal rate: 22% (the top bracket $83,900 falls into).

Effective rate: $13,170 ÷ $100,000 = 13.2% — far below the 22% marginal rate, because most of the income was taxed at 10% and 12%.

This $13,170 figure is exactly what our US salary calculator produces for a single filer on $100,000 — it applies these same 2026 brackets and standard deduction, then layers FICA and state tax on top.

Federal Tax Is Only Part of Your Paycheck

Federal income tax, calculated using the brackets above, is only one of three layers that come off your paycheck. The full stack is:

• FICA — the 7.65% Social Security + Medicare payroll tax, charged on gross wages before any deductions
• Federal income tax — the progressive brackets in this guide, applied to taxable income
• State income tax — varies by state, from zero to a top marginal rate above 10%

To see all three combined on your actual salary, run your numbers through the US Take-Home Pay Calculator — it applies the 2026 federal brackets, FICA, and your state's tax rules together.
