• The cbdt cost inflation index rises to 384 for FY2026-27, up from 376, a 2.12% increase.
• This cbdt cost inflation index adjustment applies from April 1, 2026 and affects LTCG tax calculations on long-term assets like land, property, trademarks and patents.
• Eligible taxpayers can choose between 12.5% without indexation or 20% with indexation for property gains.
• In a concrete example, indexation reduces taxable gains from Rs 50 lakh to Rs 20 lakh, and LTCG tax from Rs 6.25 lakh to Rs 4 lakh.

Property sellers face a crucial question: how will changes in cbdt ltcg tax and the cbdt cost inflation index affect long-term gains? The cbdt cost inflation index for FY2026-27 is set at 384, up from 376 in FY2025-26. This 2.12% rise applies from April 1, 2026, and it can adjust the inflation-adjusted purchase price for long-term assets such as land, property, trademarks and patents. For those eligible, the indexation option may reduce tax liability on capital gains when selling these assets. The update is framed as a tax planning detail for property sales and LTCG calculations under Indian tax rules.

Under the current regime, the long-term capital gains tax (LTCG tax) on property sales was revised in 2024, with indexation benefits removed for most capital assets. The new framework introduced a flat 12.5% LTCG tax on property gains, while the option to apply indexation remains available only in specific, older scenarios. This nuanced shift means the impact of a higher cbdt cost inflation index on your final tax bill depends on your asset class, year of purchase, and whether you qualify for the indexation option. We break down what this means for you as an investor and property owner.

As you read, remember that the key purpose of the cbdt cost inflation index is to adjust for inflation when determining the cost of acquisition for long-term assets. In practice, the higher index value in FY2026-27 increases the base cost of acquisition, which can lower the gain on sale and, hence, the LTCG tax you owe. There is a clear path for eligible taxpayers to leverage this change to optimize tax outcomes, especially when planning the sale of land or buildings purchased before July 23, 2024.

Key figures from the CBDT notification include the FY2026-27 CII of 384, up from 376 in FY2025-26, marking a 2.12% increase. The revised index will apply to tax year 2026-27 on and from the 1st day of April 2026 and for subsequent years. The 384 value is used to calculate the inflation-adjusted purchase price for eligible assets and can influence whether you opt for the old regime with indexation or the current regime without it. The asset classes impacted by this update include long-term assets such as land, property, trademarks and patents, as noted in the notification. The legal framework references Section 72(8)(a) of the Income-tax Act, 2025. This is a tax planning detail designed to inform property sale decisions, rather than a broad change to all capital asset LTCG computations.

To contextualize this with a concrete example, consider a purchase in FY2014-15 and a sale in FY2026-27. If the purchase price was Rs 50,00,000 and the sale price Rs 1,00,00,000, the inflation-adjusted (indexed) cost of acquisition would be Rs 50,00,000 × (384 ÷ 240) = Rs 80,00,000, using the 384/240 ratio from the example. The purchase cost without indexation remains Rs 50,00,000. Therefore, the gains with indexation would be Rs 1,00,00,000 − Rs 80,00,000 = Rs 20,00,000, compared with Rs 1,00,00,000 − Rs 50,00,000 = Rs 50,00,000 without indexation. The LTCG tax would be 12.5% × Rs 50,00,000 = Rs 6,25,000 without indexation, versus 20% × Rs 20,00,000 = Rs 4,00,000 with indexation. This example illustrates how the indexation benefit, in eligible cases, may significantly reduce tax liability.

Table: Worked Example With 384 CII

The numbers in the table reflect the illustrative scenario and are meant to demonstrate how indexation affects the tax payable. The actual tax will depend on your total income, other deductions, and the precise year-specific CII data for the year of purchase and sale. Investors should verify the year-specific CII from the official tax department resources when calculating their own tax liabilities for property sales.
