The IRS has issued Revenue Procedure 2026-35, setting inflation-adjusted tax brackets and other tax thresholds for 2027, including higher annual gift and estate tax exclusions and a new Education Freedom Tax Credit, while retaining the seven existing federal income tax rates ranging from 10% to 37%.
The US Internal Revenue Service (IRS) issued Revenue Procedure 2026-35 and News Release IR-2026-133 on 5 November 2026, establishing annual inflation adjustments for approximately 70 tax provisions for tax year 2027.
These statutory adjustments, governing tax returns filed during calendar year 2028, apply an annual cost-of-living indexing factor of 3.2%. This adjustment rate exceeds the inflation factors applied in the preceding two tax years, reflecting ongoing economic inflation adjustments across federal tax provisions.
The 2027 tax adjustments under IRC Section 1(f) aim to prevent bracket creep by increasing tax bracket thresholds and deduction amounts to account for inflation, while retaining the seven marginal tax rates of 10%, 12%, 22%, 24%, 32%, 35%, and 37%.
Federal income tax rate schedules by filing status
Federal individual income tax schedules maintain a progressive rate structure across seven marginal tiers. Taxpayers pay ascending marginal rates only on income within specified statutory windows. The 2027 adjustments expand these income windows across all four primary filing statuses.

For 2027, the 12% tax bracket for joint filers and qualifying surviving spouses will extend to USD 104,050, up from USD 100,800 in 2026, while the top 37% rate will apply to taxable income exceeding USD 793,650, up from USD 768,700.
