The Internal Revenue Service released new federal income tax brackets and higher standard deductions for 2027, raising income thresholds across all seven marginal rates by about 3.2% to account for inflation. Filers will see the changes on tax returns they submit in early 2028.
All seven marginal rates remain unchanged at 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The income boundaries that dictate where each rate starts have moved higher, according to the IRS.
The adjustments, detailed in Revenue Procedure 2026-35 released on November 5, 2026, affect nearly 70 tax provisions.
About nine out of ten taxpayers take the standard deduction rather than itemizing deductions such as mortgage interest. For married couples filing jointly, the standard deduction rises by $1,000 to $33,200 for tax year 2027. Single taxpayers and married individuals filing separately will see their standard deduction climb by $500 to $16,600, while heads of households receive a standard deduction of $24,925, CPA Practice Advisor reported. These annual adjustments provide notable benefits through increased credits and deductions, according to IRS Chief Executive Officer Frank J. Bisignano.

The 10% bracket covers taxable income up to $25,600 for joint filers. Single filers face a 10% rate on income of $12,800 or less.
