2027 Tax Brackets and IRS Inflation Adjustments: What Changed From 2026
Quick Answer
The IRS released its tax year 2027 inflation adjustments on November 5, 2026 (IR-2026-133, Revenue Procedure 2026-35). Tax rates stay the same, from 10% to 37%, but every bracket is wider. The standard deduction rises to $33,200 for married couples, the estate tax exemption rises to $15,480,000, and the annual gift exclusion rises to $20,000. These numbers apply to 2027 tax returns filed in 2028.
Every fall, the IRS adjusts nearly 70 tax provisions for inflation. For 2027, the tax rates themselves don’t change, but the income levels for each bracket, the standard deduction, and many credits and limits all go up. Here is what changed, side by side with 2026, and what it means for individuals, families, business owners, and estates.
