The new year brings fresh tax updates as the IRS adjusts various provisions for inflation. These changes help protect the value of tax benefits and keep pace with rising costs. Staying informed can help you fine-tune your financial plan, optimize tax strategies, and maximize your retirement savings in 2025 and beyond.
How the IRS Adjusts Taxes for Inflation
Each year, the IRS modifies tax provisions to reflect economic conditions and prevent “bracket creep,” where inflation pushes income into higher tax brackets without an actual increase in purchasing power.
Prior to 2018, these adjustments were based on the Consumer Price Index for Urban Consumers (CPI-U). However, the Tax Cuts and Jobs Act of 2017 introduced a new benchmark: the Chained Consumer Price Index (C-CPI). Unlike the traditional CPI, the C-CPI accounts for changes in consumer behavior—such as choosing cheaper alternatives when prices rise—which typically results in smaller annual adjustments to tax brackets and deductions.
