2027 Tax Brackets and Tax Calculator: The IRS Numbers, and What You’ll Owe

The 2027 federal income tax brackets

These are the IRS’s rate tables for tax year 2027, from Revenue Procedure 2026-35. They apply to taxable income, which is your income after the standard deduction or your itemized deductions.

Each rate covers only the slice of income inside its row. Moving into the 22% bracket doesn’t raise the tax on the dollars below it.

Surviving spouses use the married-filing-jointly column. The top rate starts at $661,375 for single filers and $793,650 for married couples filing jointly.

Which table goes with which tax return

This is where most of the confusion comes from. The number in “2027 tax brackets” is the year you earn the money, not the year you file.

• The return you file in early 2027 covers 2026 income, so it uses the 2026 table below.
• The 2027 table covers money you earn from Jan. 1, 2027, and the return you file in 2028.

2026 brackets, for the return you file in 2027

Every threshold moved up about 3.2% from 2026 to 2027. The seven rates themselves didn’t change.

2027 standard deduction

Most people take the standard deduction instead of itemizing. For 2027 it goes up $500 for single filers, $1,000 for married couples filing jointly and $775 for heads of household.

If you’re 65 or older or blind, you add $1,700 per person in 2027, or $2,100 if you’re unmarried and not a surviving spouse. In 2026 those were $1,650 and $2,050.

The senior deduction from the 2025 tax law is separate and doesn’t change with inflation: up to $6,000 per person 65 or older, or $12,000 for a couple who both qualify, from 2025 through 2028. You get it whether or not you itemize, and married people have to file jointly to claim it.

It shrinks by 6 cents for every dollar of modified adjusted gross income over $75,000, or $150,000 for joint filers, so it’s gone at $175,000 single and $250,000 joint. That’s the math on Schedule 1-A, and the calculator above does it for you.

Same pay, a little less tax

Here’s what the new numbers do if your income doesn’t change from 2026 to 2027. Wider brackets and a bigger standard deduction mean a few more dollars taxed at the lowest rates.

Federal income tax only, on wages, with the standard deduction and no credits. Rounded to the dollar.

The savings are small on purpose. The adjustment exists so that a raise that only keeps up with prices doesn’t push more of your pay into a higher bracket.

Other 2027 numbers in the same IRS release

• Child tax credit: up to $2,300 per child, $100 more than 2026; up to $1,800 of it is refundable. Our child tax credit calculator runs your family’s numbers for 2026 and 2027.
• Earned income tax credit: up to $8,496 with three or more qualifying children, $7,552 with two, $4,573 with one and $685 with none.
• Long-term capital gains: the 0% rate applies up to $51,050 of taxable income for single filers and $102,100 for joint filers; 15% up to $563,200 and $633,600.
• Gift tax annual exclusion: $20,000 per person you give to, up from $19,000.
• Estate tax exclusion: $15,480,000 for people who die in 2027.
• Health FSA: up to $3,500 in salary contributions; $700 can carry over where the plan allows it.

• Adoption credit: up to $18,250, with up to $5,280 refundable.

The tips, overtime and car-loan interest deductions work the same way in 2027: up to $25,000 of qualified tips, $12,500 of qualified overtime pay ($25,000 joint) and $10,000 of interest on a loan for a qualifying new vehicle. Those caps are set in the 2025 law rather than the inflation tables, and like the senior deduction they run through 2028.

The 2027 401(k) and IRA limits came out separately, on Nov. 12: $25,500 for a 401(k) and $7,500 for an IRA. Our 401(k) limit calculator shows the catch-up for your age and what it takes per paycheck.

How we figured the tax

We took each example income, subtracted that year’s standard deduction and ran the result through the IRS rate tables for 2026 and 2027, then rounded to the dollar.

The calculator does the same with your numbers. It adds the extra standard deduction for 65 or older or blind, and the senior deduction with its 6% phase-out, from IRS Schedule 1-A. It stops before credits, so the child tax credit and others come off the number it shows.

It uses the IRS rate schedules. Below $100,000 of taxable income the IRS tax table works in $50 steps, so your return can differ from the calculator by a few dollars.

The 3.2% is our comparison of the 2027 thresholds with the 2026 ones in the two revenue procedures. Your own return will differ with other income, credits and deductions.
