The Central Board of Direct Taxes (CBDT) has raised the Cost Inflation Index (CII) for FY27 to 384, up 2.12% from 376 in FY26. Effective April 1, the revised index will be used to calculate long-term capital gains (LTCG) tax for eligible taxpayers. The higher CII means that people selling long-term assets may end up paying lower LTCG tax.
