Indexation Formula for LTCG (Cost Inflation Index – CII)

Indexed Cost =

(Actual Cost × CII of Sale Year) / CII of Purchase Year

Example:

  • Purchase Year (2018-19): CII = 280
  • Sale Year (2023-24): CII = 348
  • Purchase Price: ₹50 lakh
  • Indexed COA: ₹50L × (348/280) = ₹62.14 lakh

Special Cases in Capital Gains Computation

SCENARIO TAX TREATMENT
Inherited Assets COA = Previous owner’s purchase cost (indexed from their holding period)
Gifted Assets COA = Market value on gift date (or donor’s cost if gifted before 2001)
Self-Generated Assets COA = Nil (e.g., goodwill, patents) unless purchased
Bonus Shares COA = Zero (holding period starts from allotment date)
Property Undervaluation Higher of actual sale value or stamp duty value considered (Section 50C)

Illustrative Example (Property Sale)

PARTICULARS AMOUNT (₹)
Sale Price (2023-24) 1,20,00,000
Purchase Price (2015-16) 50,00,000
Indexed COA (CII 348/254) 68,50,393
Improvement Cost (2018-19) 10,00,000
Indexed COI (CII 348/280) 12,42,857
Brokerage Paid 1,00,000
Taxable LTCG 38,06,750
Tax @ 20% 7,61,350

TIPS :

  1. STCG: No indexation benefit; taxed at slab rates or 15% (for equity).
  2. LTCG: Indexation reduces tax liability (20% on gains).
  3. Documentation: Maintain purchase/sale deeds, improvement bills, and expense receipts.
  4. Exemptions: Reinvestment benefits under Sections 54, 54EC, 54Fcan reduce tax.
