CBDT raises Cost Inflation Index to 384 for FY 2026-27
Synopsis
Key Takeaways
The Central Board of Direct Taxes (CBDT) has raised the Cost Inflation Index (CII) for financial year 2026-27 to 384, up 2.3% from 376 in the previous year. The official notification was issued on 15 July 2026 and takes effect from 1 April 2026 for all applicable tax calculations.
What the Cost Inflation Index Does
The CII adjusts the original purchase price of a capital asset — such as land or property — for inflation accumulated over the years of ownership. By inflating the cost base, it reduces the computed long-term capital gain, and consequently the tax owed, when the asset is sold. This mechanism is designed to ensure taxpayers are not penalised for nominal price appreciation that merely reflects inflation rather than real economic gain.
Limited Applicability After Finance Act 2024
Notably, the practical reach of the CII has narrowed significantly. Following amendments introduced under the Finance Act, 2024, indexation benefits have been discontinued for most long-term capital assets transferred on or after 23 July 2024. A flat 12.5% tax rate now applies to such transfers, without indexation.
The CII retains relevance only in a grandfathered scenario: resident individuals and Hindu Undivided Families (HUFs) selling land or buildings acquired before 23 July 2024 may choose between the new 12.5% rate without indexation and the older 20% rate with indexation — whichever results in a lower tax liability. For this segment, the revised CII of 384 could meaningfully reduce the taxable gain.
Direct Tax Collections Surge in FY 2026-27
The CII revision comes against the backdrop of a strong direct tax performance. India's net direct tax collections grew 16.4% year-on-year to ₹6.51 lakh crore as of 13 July 2026, according to CBDT data.
Within that, net corporate tax collections rose over 22% to approximately ₹2.40 lakh crore, while net non-corporate tax collections climbed around 12% to ₹3.85 lakh crore. Securities Transaction Tax (STT) collections surged over 44% to more than ₹26,000 crore, reflecting heightened equity market activity.
What Taxpayers Should Know
For most property sellers, the flat 12.5% regime introduced in 2024 will apply automatically. However, those who acquired land or buildings before 23 July 2024 retain the option to compute tax under both regimes and opt for the lower figure. Tax experts advise running both calculations before filing, as the better outcome will vary depending on the asset's holding period and original acquisition cost. The CBDT notification ensures the updated CII is available for such computations from the start of the current financial year.
