The Central Board of Direct Taxes (CBDT) in India has officially announced the Cost Inflation Index (CII) at 384 for the financial year 2026-27 (FY27). This index, a vital component in calculating long-term capital gains, will be effective from April 1, 2026, for Tax Year 2026-27 and subsequent tax years, as per Section 72 of the Income-tax Act, 2025.
Understanding the Cost Inflation Index (CII)
The CII is an annual number published by the CBDT to account for inflation when determining long-term capital gains (LTCG). Instead of taxing the full difference between an asset's purchase and sale price, indexation adjusts the original acquisition cost upwards to reflect inflation. This effectively reduces the taxable capital gain, thereby lowering the tax liability for the seller.
For instance, if an asset was bought several years ago, its 'indexed cost' will be higher than its actual purchase price due to the inflation adjustment. The new index of 384 for FY27 represents an increase from 376 in FY26, indicating a rise in inflation over the past year.
Who Can Claim Indexation Benefits?
It is important to note that the notification of the new CII does not mean all capital asset sales are eligible for indexation. Significant changes introduced in the Union Budget 2024 largely restricted indexation benefits for most newly acquired capital assets.
However, specific categories of taxpayers can still avail themselves of this benefit. A key group includes resident individuals and Hindu Undivided Families (HUFs) selling land or buildings that were acquired before July 23, 2024. These taxpayers may opt for the earlier capital gains tax regime, which includes indexation, if it results in a lower tax burden compared to the newer tax framework. For these eligible sales, the newly notified CII of 384 will be used to compute the indexed cost of acquisition.
Significance for Taxpayers and Professionals
While the annual CII notification is a routine administrative process, it provides critical clarity and certainty for taxpayers, chartered accountants, and other tax professionals involved in capital gains calculations. The index acts as the official benchmark for determining indexed acquisition costs wherever indexation is still permitted under the Income-tax Act.
Taxpayers planning to sell eligible immovable property during FY2026-27 should factor the new CII into their financial planning. Comparing the potential tax liability under the old indexation regime versus the newer capital gains framework is crucial for optimizing tax outcomes. The notification underscores that despite recent tax reforms limiting its scope, indexation continues to offer meaningful tax savings for those disposing of specific long-held assets.
