Based on the inflation data the IRS uses, the 2027 tax brackets are projected to rise about 3.2%. For single filers, the 10% rate would apply to the first $12,800 of taxable income and the top 37% rate to income over $661,375 ($793,625 for married couples filing jointly). The standard deduction would be $16,600 for single filers, $33,200 for married couples filing jointly and $24,900 for heads of household. The IRS usually announces the official figures in October or November.
Key facts
- The seven rates stay the same in 2027: 10%, 12%, 22%, 24%, 32%, 35% and 37%. The 2025 tax law made them permanent; only the income thresholds move with inflation.
- Projected increase: about 3.2%, based on the chained CPI for September 2025 through August 2026.
- These brackets apply to income earned in 2027, on the tax return filed in 2028. For the return you file in 2027, use the 2026 tax brackets.
- We will replace these projections with the official IRS amounts as soon as they are published. Projection as of September 29, 2026.

How we projected the 2027 brackets
The tax law adjusts brackets each year by the change in the average chained Consumer Price Index (C-CPI-U) over the 12 months ending August 31. We took the official 2026 amounts and increased them by the growth in that average from the period behind the 2026 figures to September 2025–August 2026, about 3.25%, then rounded down the way the IRS does ($25 for brackets and capital-gains breakpoints, $50 for the standard deduction). Married-filing-jointly thresholds for the 10% to 32% brackets are twice the single amounts, as the law requires.
BLS did not publish an October 2025 index (federal government shutdown). The projection averages the 11 available months. Recent months are initial or interim values subject to revision. Official figures may differ slightly from these projections.
Frequently asked questions
What are the 2027 tax brackets?
Projected for single filers: 10% up to $12,800, 12% up to $52,025, 22% up to $109,125, 24% up to $208,300, 32% up to $264,525, 35% up to $661,375 and 37% above that. The thresholds for married couples filing jointly are twice as high up to the 32% bracket.
What is the standard deduction for 2027?
The projected 2027 standard deduction is $16,600 for single filers and married people filing separately, $33,200 for married couples filing jointly and $24,900 for heads of household, up from $16,100, $32,200 and $24,150 in 2026. The extra amount for age 65+ or blindness would be $2,100 ($1,700 if married).
When will the IRS announce the 2027 tax brackets?
The IRS publishes next year’s inflation adjustments in the fall. It released the 2026 amounts on October 9, 2025, so the 2027 figures are expected around October or November 2026. We update this page as soon as they are out.
How accurate are these 2027 projections?
They use the same inflation measure and rounding rules the law requires, so they are typically within a small rounding amount of the official numbers. Two things can make them differ: later revisions to recent inflation data, and how the IRS handles the October 2025 month, for which the Bureau of Labor Statistics published no index.
Will I pay less tax in 2027?
If your income stays the same, slightly less: wider brackets and a larger standard deduction shield more income. A single filer earning $75,000 would owe about $281 less federal income tax ($7,670 under 2026 rules vs. $7,390 under the 2027 projection). A raise that only keeps up with inflation won’t push you into a higher bracket.
