Section 43CA of the Income Tax Act, 1961 addresses the taxation of undervalued transactions involving business assets (non-capital assets) such as inventory, land, or building held as stock-in-trade.
1. Key Features of Section 43CA
- Objective: Prevents underreporting of sale consideration for non-capital assets(e.g., real estate held as stock-in-trade).
- Applicability:
- Sellersengaged in real estate business (buildings/land held as inventory).
- Buyersmay also face implications under Section 56(2)(x) if undervaluation is detected.
- Tax Treatment: If the actual sale price < stamp duty value (SDV), the higher value (SDV) is deemed as sale considerationfor tax purposes.
2. When Does Section 43CA Apply?
| SCENARIO | TAX IMPACT |
| Property sold below stamp duty value | SDV is considered as sale value |
| Cash component not recorded | Full SDV taxable (even if cash is unaccounted) |
| Sale to relatives at lower price | SDV used unless proved as arms-length transaction |
Example:
- A builder sells a flat for ₹50 lakh, but the stamp duty value is ₹70 lakh.
- Taxable sale value = ₹70 lakh(even if ₹50 lakh was received).
3. Exceptions & Adjustments
✔ 5% Margin Allowance: If sale price is ≥ 95% of SDV, no adjustment is made.
✔ Subsequent Resale Within 1 Year: If buyer resells the property within a year, the original seller’s SDV adjustment does not apply.
4. Compliance & Penalties
- Disclosure in ITR: Must report both actual sale price and SDV.
- Penalty Risk:
- Concealment (Section 271(1)(c)): 100–300% of tax evaded.
- Prosecutionin extreme cases.
