IRS Adjusts 2027 Tax Brackets and Deductions to Combat Inflation

The Internal Revenue Service (IRS) announced on Thursday that federal income tax brackets for the 2027 tax year will be adjusted to account for inflation. This move, which impacts over 160 million individual taxpayers, is designed to shield a larger portion of personal income from higher tax rates as the cost of living continues to rise.

Starting January 1, 2027, income thresholds for the seven federal tax brackets—ranging from 10% to 37%—will increase by an average of 3.2%. While Congress sets the actual tax rates, the IRS annually updates the income ranges to prevent "bracket creep," a phenomenon where cost-of-living pay raises push taxpayers into higher tax brackets despite no increase in their actual purchasing power.

In addition to the bracket adjustments, the standard deduction will see a notable increase for the 2027 filing year. Single filers will see their standard deduction rise to $16,600, while married couples filing jointly will see an increase to $33,200. These figures represent a $500 increase for single filers and a $1,000 increase for married couples compared to the 2026 tax year.

The IRS noted that nearly 70 different tax provisions are impacted by these inflation-related adjustments. Among these changes, the child tax credit is set to rise from $2,200 to $2,300 per qualifying child, with the maximum refundable portion of that credit increasing to $1,800. Furthermore, the maximum earned income tax credit for taxpayers with three or more qualifying children will climb to $8,496.

These adjustments are calculated using the chained consumer price index (chained CPI), a metric that has been utilized for tax indexing since 2018. The decision follows a period of persistent inflation, which reached 3.7% as of September, driven largely by rising household costs and fuel prices. Taxpayers will generally file returns reflecting these new brackets and deductions in early 2028.

For the average taxpayer, these changes may result in modest tax savings. For example, a single filer earning $100,000 who claims the standard deduction could see their tax liability drop by approximately $281 in 2027, provided their other financial circumstances remain unchanged. While most Americans opt for the standard deduction, the IRS continues to advise that itemizing expenses may still be beneficial for those with significant state and local tax or mortgage interest deductions.
