# Property Capital Gains Calculator

> Calculate STCG or LTCG tax on selling a property, with Section 54 and 54EC exemptions.

Interactive calculator: https://awesomecalcs.com/property-capital-gains-calculator

## How this is calculated

Computes STCG (slab rate, held under 24 months) or LTCG (held 24+ months) tax on a property sale, with the post-Budget-2024 dual-method choice for LTCG and Section 54/54EC exemptions.

**Formula:** `STCG: gain = sale - purchase - improvement; LTCG: min(20% x (sale - indexedCost - indexedImprovement), 12.5% x (sale - purchase - improvement)) after Sec 54/54EC exemptions`

**Variables:**

- `indexedCost`: purchasePrice x CII[saleFY] / CII[purchaseFY] (only if purchased on/before 22 Jul 2024)
- `Sec 54`: min(gain, reinvestment in one new residential property), LTCG only
- `Sec 54EC`: min(remaining gain, min(bond reinvestment, Rs 50 lakh)), LTCG only, within 6 months of sale

Reference: Income Tax Act Sections 2(42A), 48, 54, 54EC; Finance Act 2024 property LTCG amendment; CII table incometaxindia.gov.in (verified July 2026).

## Assumptions

- TODO: re-verify this rule every FY. Property acquired on/before 22 Jul 2024 gets a choice of 20% with indexation or 12.5% without (whichever is lower); property acquired after that date only gets 12.5% without indexation. This rule changed in Budget 2024 and remains an active topic.
- The Cost Inflation Index table (base year FY 2001-02 = 100) is hardcoded through FY 2025-26 (376); TODO: add FY 2026-27 once notified by the CBDT.
- Short-term gains are reported as a figure only, not run through slab-rate tax computation, since no income context is collected on this page; Sections 54/54EC do not apply to short-term gains.

## Frequently asked questions

### How do I know if my gain is short-term or long-term?

Property held for less than 24 months from purchase to sale is short-term, taxed at your income slab rate. Property held 24 months or more is long-term, eligible for the indexation choice (if bought before 23 Jul 2024) and Section 54/54EC exemptions.

### Why does this calculator show two tax figures for long-term gains?

For property acquired on or before 22 July 2024, the Budget 2024 amendment lets you choose between 20% tax with indexation (adjusting your purchase price for inflation) or 12.5% tax without indexation, whichever is lower for you. This calculator computes both and picks the cheaper one. Property acquired after that date only gets the 12.5% no-indexation option.

### What is indexation and why does it lower my tax?

Indexation adjusts your original purchase price upward for inflation using the Cost Inflation Index (CII), a government-published table. A higher adjusted cost means a lower taxable gain, which can offset the higher 20% tax rate, especially for property held a long time with modest appreciation relative to inflation.

### How does the Section 54 exemption work?

If you reinvest your long-term capital gain into one new residential property (within specific time windows around the sale), you can claim an exemption up to the amount reinvested, capped at your total gain. Section 54 exemptions only apply to long-term gains, not short-term.

### What are Section 54EC bonds?

Section 54EC lets you invest your long-term capital gain in specified bonds (issued by REC, NHAI, and similar institutions) within 6 months of the sale, exempting up to Rs 50 lakh of your gain. This is a separate exemption from Section 54 and can be used together with it on the remaining gain.

### Why does this calculator flag the indexation rule for annual verification?

The property LTCG tax rule already changed once in Budget 2024 (removing indexation for most assets, with a special dual-choice carve-out for property), and remains a topic of ongoing debate in subsequent Budgets. Always verify the current-year rule with a tax professional before relying on this for a filing decision.
