On a yearly basis the Internal Revenue Service (IRS) adjusts more than 60 tax provisions for inflation to prevent what is called “bracket creep.” Bracket creep occurs when people are pushed into higher income tax brackets or have reduced value from credits and deductions due to inflation, instead of any increase in real income.
The IRS used to use the Consumer Price Index (CPI) as a measure of inflation prior to 2018. However, with the Tax Cuts and Jobs Act of 2017 (TCJA), the IRS now uses the Chained Consumer Price Index (C-CPI) to adjust income thresholds, deduction amounts, and credit values accordingly.
The new inflation adjustments are for tax year 2023, for which taxpayers will file tax returns in early 2024. Note that the Tax Foundation is a 501(c)(3) educational nonprofit and cannot answer specific questions about your tax situation or assist in the tax filing process.
