IRS Tax Brackets 2027: What We Know Before the Official Numbers Arrive
The IRS has not yet published 2027 tax brackets. Here is what is known, the projected standard deduction, and which year's brackets apply to your next return.
The IRS has not yet published the official 2027 federal income tax brackets and standard deduction as of Nov. 4, 2026. The agency issues them each fall in a revenue procedure; last year’s came out on Oct. 9, 2025. We will update this article the day the new figures appear.
Which brackets apply to you right now
Your return due in spring 2027 covers income earned in 2026 and uses the 2026 brackets and standard deduction, which are already set. For 2026, the standard deduction for a single filer is $16,100.
The 2027 numbers matter for next year’s income: withholding, estimated payments and planning for 2027.
What to expect
The seven tax rates are set by law: 10%, 12%, 22%, 24%, 32%, 35% and 37%. Each year the income thresholds where those rates begin are adjusted for inflation, which the Federal Reserve still calls elevated. Bloomberg Tax projects an inflation adjustment of about 3.2% for 2027. Applying that, forecasters estimate:
Filing status
2026 standard deduction
Projected 2027 (estimate)
Single
$16,100
about $16,600
Married filing jointly
$32,200
about $33,200
Head of household
not confirmed
about $24,950
These 2027 numbers are projections from tax-research firms, not IRS figures, and they may differ from the final amounts.
