Explanation:
Every year, the IRS makes adjustments on more than 40 tax provisions for inflation. This is to prevent what is called “bracket creep,” 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 would use the Consumer Price Index (CPI) to calculate the past year’s inflation. 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.
