Cost Inflation Index (CII) — Discovery
What is CII?
- Cost Inflation Index (CII) is a number published annually by the Central Board of Direct Taxes (CBDT) under Section 48 of the Income Tax Act.
- It measures inflation and is used to compute the indexed cost of acquisition for long-term capital gains (LTCG) tax purposes.
- Base year: FY 2001-02 (CII = 100).
