Every year the IRS adjusts more than 40 tax provisions for inflation.
The IRS used to use the Consumer Price Index (CPI) to calculate the past year’s inflation.[1] However, with the Tax Cuts and Jobs Act of 2017, the IRS will now use the Chained Consumer Price Index (C-CPI) to adjust income thresholds, deduction amounts, and credit values accordingly.[2]
