Indexation Benefit on Property Sale India 2026 — LTCG Calculation After Budget Changes

The Budget 2024 Change: What Shifted

The Union Budget presented on July 23, 2024 was a watershed moment for property sellers. The finance minister changed the LTCG tax on immovable property:

Pre-July 23, 2024Post-July 23, 2024
LTCG tax rate20%12.5%
IndexationAvailableNot available
Effective forAll qualifying transactionsNew purchases from July 23, 2024

Grandfathering provision: For properties purchased before July 23, 2024, taxpayers can choose between:

  • Option A: 12.5% tax WITHOUT indexation
  • Option B: 20% tax WITH indexation
    Pick whichever gives a lower tax liability.

Understanding Indexation (For Context)

Cost Inflation Index (CII): Published by the Income Tax department annually. Used to adjust the purchase price for inflation.

Formula (Old system): Indexed Cost of Acquisition = Purchase Price × (CII of sale year ÷ CII of purchase year)

LTCG = Sale Price - Indexed Cost - Indexed Improvement Costs

Key CII values:

YearCII
2001–02 (base)100
2010–11167
2015–16254
2020–21301
2024–25363
2025–26~375 (approx)

Choosing Between Options: Worked Examples

Example 1: Pune Flat Bought 2013, Selling 2026

DetailValue
Purchase price (2013)₹35L
Sale price (2026)₹1.10 Cr
Holding period13 years → Long Term
CII 2013–14220
CII 2025–26~375

Option A: 12.5% without indexation

  • Gain = ₹1.10 Cr - ₹35L = ₹75L
  • Tax = ₹75L × 12.5% = ₹9.38L

Option B: 20% with indexation

  • Indexed cost = ₹35L × (375 ÷ 220) = ₹59.7L
  • Gain = ₹1.10 Cr - ₹59.7L = ₹50.3L
  • Tax = ₹50.3L × 20% = ₹10.06L

Winner: Option A (12.5%) — saves ₹68,000


Example 2: Flat Bought 2010, Selling 2026

DetailValue
Purchase price (2010)₹28L
Sale price (2026)₹95L
CII 2010–11167
CII 2025–26~375

Option A: 12.5% without indexation

  • Gain = ₹95L - ₹28L = ₹67L
  • Tax = ₹67L × 12.5% = ₹8.38L

Option B: 20% with indexation

  • Indexed cost = ₹28L × (375 ÷ 167) = ₹62.9L
  • Gain = ₹95L - ₹62.9L = ₹32.1L
  • Tax = ₹32.1L × 20% = ₹6.42L

Winner: Option B (20% with indexation) — saves ₹1.96L

Rule of thumb: The longer the holding period and the lower the absolute appreciation (value barely kept up with inflation), the more likely 20% with indexation wins.


Example 3: Hinjewadi Flat Bought 2020, Selling 2026

DetailValue
Purchase price (2020)₹80L
Sale price (2026)₹1.30 Cr
Holding6 years → Long Term
CII 2020–21301
CII 2025–26~375

Option A: 12.5% without indexation

  • Gain = ₹1.30 Cr - ₹80L = ₹50L
  • Tax = ₹50L × 12.5% = ₹6.25L

Option B: 20% with indexation

  • Indexed cost = ₹80L × (375 ÷ 301) = ₹99.7L
  • Gain = ₹1.30 Cr - ₹99.7L = ₹30.3L
  • Tax = ₹30.3L × 20% = ₹6.06L

Winner: Option B (20% with indexation) — barely, saves ₹19,000


Section 54: Reinvestment Exemption Still Works

Even under the new regime, reinvestment in another residential property can exempt your capital gains:

Section 54: Invest the LTCG amount (not the full sale price) in a new residential property within:

  • 1 year before sale, or
  • 2 years after sale, or
  • 3 years after sale if constructing

Maximum exemption: Full LTCG amount can be exempted if fully reinvested.

Capital Gains Account Scheme (CGAS): If you can’t reinvest within the financial year of sale, deposit the gains in a CGAS bank account before ITR filing. This preserves the Section 54 benefit.


LTCG for Properties Purchased After July 23, 2024

No choice here — the law is clear:

  • Rate: 12.5%
  • No indexation
  • No grandfathering

For buyers from 2024 onwards: the way to minimise LTCG on future sale is:

  1. Hold for 24+ months (Long Term threshold)
  2. Utilise Section 54 reinvestment
  3. Factor in acquisition cost improvements (renovation, capital improvements add to cost basis)

Calculating Your Actual Tax: What Reduces Taxable Gains

Purchase cost includes:

  • Stamp duty paid at purchase
  • Registration charges
  • Brokerage paid
  • Legal fees for property purchase

Improvement costs:

  • Capital improvements (renovation, additional construction) — documented with receipts and completion certificate where possible
  • Does NOT include routine maintenance

Example: ₹80L flat, ₹3L stamp duty, ₹2L brokerage, ₹5L renovation:

  • Total cost basis = ₹80L + ₹3L + ₹2L + ₹5L = ₹90L
  • Sale price ₹1.30 Cr
  • LTCG (12.5% option) = ₹40L × 12.5% = ₹5L (vs ₹6.25L without cost additions)

Always document and include all acquisition costs.


FAQs

Q: Do I pay LTCG on the entire sale price? No — LTCG is on gains (sale price minus indexed or actual cost basis). You don’t pay tax on returning your own capital. Only the profit portion is taxed.

Q: What if my property is jointly owned? Each owner calculates LTCG on their proportionate share and files separately. If the property was 50-50, each owner declares 50% of the gain and can each claim Section 54 exemption on their share by reinvesting in a new property.

Q: How does surcharge affect my LTCG tax? LTCG on property: 12.5% base rate + 10% surcharge (if income exceeds ₹50L) + 4% health and education cess. Effective rates: up to ~14.95% for high-income sellers. For most salaried buyers selling one property: effective rate closer to 13%.
