2026 Federal Tax Brackets: How Marginal Rates Actually Work

Few tax ideas are misunderstood as often as the bracket. The belief that a raise can push you into a higher bracket and leave you with less take-home pay is common, and it is wrong. The IRS puts it plainly: when your income jumps to a higher tax bracket, "you don't pay the higher rate on your entire income. You pay the higher rate only on the part that's in the new tax bracket." This guide shows the 2026 numbers and works through an example.

The 2026 brackets

The figures below come from the IRS's tax-year 2026 inflation adjustments (IR-2025-103), which reflect the amendments made by the One, Big, Beautiful Bill. They apply to income earned in 2026, and the IRS says they generally apply to returns filed in 2027. They are taxable income thresholds, meaning income after the standard or itemized deduction.

| Rate | Single | Married filing jointly | |---|---|---| | 10% | $12,400 or less | $24,800 or less | | 12% | Over $12,400 | Over $24,800 | | 22% | Over $50,400 | Over $100,800 | | 24% | Over $105,700 | Over $211,400 | | 32% | Over $201,775 | Over $403,550 | | 35% | Over $256,225 | Over $512,450 | | 37% | Over $640,600 | Over $768,700 |

The IRS release also lists the 2026 standard deduction: $16,100 for single filers and married filing separately, $32,200 for married filing jointly, and $24,150 for head of household. Head of household bracket thresholds are in the IRS's Revenue Procedure 2025-32, which the release points to. They are not repeated here.

A worked example (single filer, 2026 brackets)

Say a single filer has $60,000 of taxable income. Each slice is taxed at its own rate:

• First $12,400 at 10% = $1,240
• Next $38,000 (from $12,400 to $50,400) at 12% = $4,560
• Remaining $9,600 (from $50,400 to $60,000) at 22% = $2,112

Total federal income tax on that taxable income: $7,912. This example is illustrative arithmetic on the IRS thresholds above, not tax advice, and it leaves out credits, other taxes and any income taxed under different rules.

Two numbers come out of it:

• Marginal rate: 22%. This is the rate on the next dollar of taxable income.
• Effective rate: about 13.2%. That is $7,912 divided by $60,000.

If this filer earned $1,000 more, only that $1,000 would be taxed at 22%. The first $60,000 would be taxed exactly as before, so a raise does not reduce what you take home.

Why the standard deduction matters first

The brackets apply to taxable income, not to your paycheck. Most filers subtract the standard deduction before any bracket applies. A single filer with $76,100 of income and no other adjustments would have $60,000 of taxable income after the $16,100 standard deduction, which is the figure used in the example above. Adjustments, credits and itemizing change the result, so your own return will differ.

What to do with this

• Use the marginal rate for decisions about extra income or deductions. It tells you what the next dollar costs in federal income tax.
• Use the effective rate to compare your overall tax burden from year to year.
• Check the year. If you are filing in early 2026, you use the 2025 brackets. The IRS's rates and brackets page shows the current-year tables and links to the 2026 release.
• Get your own numbers checked. If your situation involves business income, capital gains or itemized deductions, a credentialed preparer can model it. See how to verify a tax preparer's PTIN or CPA license.

State income taxes, payroll taxes and the rules for capital gains are separate from these brackets and are not covered here.

How we sourced this

Every bracket threshold and deduction above comes from the IRS's own tax-year 2026 announcement, and the marginal-rate explanation is quoted from the IRS rates and brackets page, both retrieved October 10, 2026. We list our sources for the same reason we publish our editorial standards: you can check each figure yourself.

The takeaway

A tax bracket is a ladder, not a cliff. Only the slice of income above each threshold is taxed at the higher rate, so your marginal rate is always higher than your effective rate. Use the 2026 IRS tables for income you earn this year, and remember they apply to returns filed in 2027.
