What is the Cost Inflation Index (CII) for FY 2024-25?

The Cost Inflation Index (CII) for FY 2024-25 is 363, as notified by CBDT. The base year is FY 2001-02 (CII = 100). The CII has increased from 100 in 2001-02 to 363 in 2024-25 — reflecting approximately 3.6x cumulative inflation over 23 years. The CII is used to compute indexed cost of acquisition for LTCG on capital assets held for more than 24 months (property) or 36 months (debt mutual funds).

How has Budget 2024 changed the indexation rules for property?

Budget 2024 (effective July 23, 2024) changed the default LTCG rate for immovable property from 20% with indexation to 12.5% without indexation. However, a special provision allows taxpayers to choose: for property acquired before July 23, 2024, you can opt for EITHER 20% with indexation OR 12.5% without indexation — whichever results in lower tax. For property acquired on or after July 23, 2024, only the 12.5% rate without indexation applies. This is a significant change for long-term property holders.

Can I claim exemption on LTCG from property sale?

Yes. Several exemptions allow you to reduce or eliminate LTCG tax: Section 54 (reinvest in new residential property within 1-2 years — up to ₹10 crore); Section 54F (for sale of non-residential capital assets, reinvest net consideration in residential property); Section 54EC (invest LTCG up to ₹50 lakh in specified bonds — NHAI, REC — within 6 months; 5-year lock-in); Section 54B (agricultural land, reinvest in agricultural land); Section 54GB (startup investments). Each has specific conditions and timelines.

What is the holding period for LTCG on property?

For immovable property (land, buildings), the holding period for LTCG is more than 24 months (2 years). Property held for 24 months or less qualifies as Short Term Capital Assets and STCG is taxed at slab rate. For listed equity, the threshold is 12 months. For debt mutual funds, it was previously 36 months for LTCG (with indexation), but since Budget 2023, all debt MF gains are taxed at slab rate regardless of holding period.

How do I determine the FMV of property purchased before April 1, 2001?

The FMV as on April 1, 2001 can be determined using: (1) A certificate from a registered government-approved valuer — this is the most defensible method; (2) Municipal valuation as of April 1, 2001; (3) Comparable sales data for similar properties in the same locality around that date. The CBDT specifies that the value should be as registered valuer's report, and the FMV cannot exceed the actual sale price. A professional valuation is strongly recommended to avoid Income Tax scrutiny.

Is stamp duty paid on purchase included in the cost of acquisition?

Yes. The cost of acquisition for capital gains purposes includes: actual purchase price, stamp duty paid, registration charges, legal fees for property purchase, and any other costs directly incurred for acquiring the property. These costs are also eligible for indexation from the year they were paid. Including all these costs in the indexed cost computation reduces the taxable LTCG.

What happens if the indexed cost exceeds the sale price?

If the indexed cost of acquisition exceeds the sale price (creating a loss), it is a Long Term Capital Loss (LTCL). LTCL can be carried forward for 8 years and set off only against LTCG from any capital asset (not against STCG or income from other sources). You must file your ITR before the due date to be eligible to carry forward this loss.

What is Section 54EC (Capital Gains Bonds) exemption?

Section 54EC allows exemption from LTCG on property by investing the capital gains (up to ₹50 lakh per financial year) in specified long-term bonds issued by NHAI (National Highways Authority of India) or REC (Rural Electrification Corporation) within 6 months of the sale date. These bonds have a 5-year lock-in period and earn interest at approximately 5-5.5% (taxable). This is useful when you don't want to buy property but want to save LTCG tax.
