Capital Gain Computation Services — STCG LTCG Classification, Cost Inflation Index, Budget 2024 Transitional Options & NRI Advisory

Capital Gain Computation Services in India

Capital gain computation sounds straightforward in principle — sale price minus purchase price equals gain. In practice, it is one of the most complex areas of Indian income tax, with different rules for different asset types, different holding period thresholds, inflation indexation that requires knowing the Cost Inflation Index for each year from purchase to sale, special rules for inherited and gifted assets, Budget 2024 transitional options requiring parallel computations for pre-July 2024 property purchases, specific provisions for assets bought before the CII base year of April 2001, and a completely different framework for NRIs claiming DTAA benefits.

N D Savla & Associates provides complete capital gain computation services for individuals, NRIs, and businesses across Mumbai and India — covering all capital asset categories: property (residential and commercial), land, listed and unlisted shares, mutual funds, business assets, gold, and inherited or gifted assets. Every computation integrates our broader capital gain on sale of property services and capital gain on securities services into a unified tax return filing engagement.

STCG vs LTCG — Why the Difference Matters

Every capital gain computation begins with a single threshold question: is the gain Short-Term or Long-Term? The answer determines the tax rate — and the difference can be dramatic. A Short-Term Capital Gain on unlisted shares is taxed at the investor's slab rate (30% for most business owners). A Long-Term Capital Gain on the same unlisted shares is taxed at 12.5% flat (post Budget 2024). The holding period threshold varies by asset type:

• Listed equity shares and equity mutual funds: More than 12 months = LTCG. 12 months or less = STCG.
• Unlisted shares: More than 24 months = LTCG. 24 months or less = STCG.
• Immovable property (house, land, commercial): More than 24 months = LTCG. 24 months or less = STCG.
• Debt mutual funds (purchased after 1 April 2023): No LTCG benefit regardless of holding period — all gains taxed at slab rate.
• Debt mutual funds (purchased before 1 April 2023): More than 36 months = LTCG at 20% with indexation. 36 months or less = STCG at slab rate.
• Gold, jewellery, other capital assets: More than 24 months = LTCG. 24 months or less = STCG.

?? The holding period is computed from the date of acquisition to the date of transfer — not the date of registration of the sale deed. For property, the date of transfer is typically when possession is handed over or the agreement for sale is executed. This distinction matters particularly for under-construction property transactions.

The Cost Inflation Index — How It Is Applied

The Cost Inflation Index (CII) is a factor notified annually by the CBDT under Section 48(iii), based on the Consumer Price Index for urban non-manual employees. It is used to compute the indexed cost of acquisition and improvement for LTCG on assets where indexation is available. For the current CII notifications, refer to the Income Tax Department at incometax.gov.in.

Formula: Indexed Cost of Acquisition = Actual Cost × (CII of Year of Sale ÷ CII of Year of Purchase)

Example: Property purchased in FY 2005-06 for ?30 lakh. Sold in FY 2024-25. CII of FY 2005-06 = 117. CII of FY 2024-25 = 363. Indexed Cost = ?30L × (363/117) = ?93.08 lakh. If the property is sold for ?1 crore, the taxable LTCG is ?1 crore minus ?93.08 lakh = ?6.92 lakh (not ?70 lakh, which would be the unindexed gain). This is the power of indexation.

The Full Capital Gain Computation Formula — Step by Step

Step 1: Determine the Full Value of Consideration

The full value of consideration is typically the sale price received or receivable. For immovable property under Section 50C: if the sale price is lower than the stamp duty value (circle rate), the stamp duty value is deemed to be the consideration. Exception: if the actual price is more than 90% of the stamp duty value, the actual price is used. The 10% tolerance buffer prevents minor differences from triggering the Section 50C deeming.

Step 2: Determine the Cost of Acquisition

For assets purchased before the CII base year (1 April 2001): the cost of acquisition is the higher of (a) the actual purchase price, or (b) the Fair Market Value (FMV) as on 1 April 2001. The seller should always get a registered valuer's report for pre-2001 assets — it often significantly exceeds the actual purchase price and reduces the taxable gain.

For inherited or gifted assets: the previous owner's cost of acquisition is the cost for the current seller. For bonus shares (listed): the cost is NIL. For rights shares: the subscription price paid is the cost.

Step 3: Compute the Indexed Cost (for LTCG where indexation applies)

Indexed Cost of Acquisition = Actual Cost (or FMV as on 1 April 2001, if pre-2001) × (CII of year of sale ÷ CII of year of purchase or 2001-02, whichever is later). The same indexation formula applies to the Cost of Improvement. For Budget 2024 property transactions: compute both (a) 12.5% without indexation and (b) 20% with indexed cost. Choose the option with lower tax liability. Document the comparison calculation for ITR filing.

Step 4: Cost of Improvement

Cost of Improvement includes all capital expenditure on the asset that increases its value — for property: construction of additional floors, major renovation, structural extension. It does NOT include: routine maintenance and repairs (which are revenue expenses); depreciation; expenses deductible as business expenses. Cost of Improvement incurred before 1 April 2001 is ignored for capital gains purposes.

Step 5: Expenses on Transfer

Deductible from the sale consideration: brokerage paid to the broker on the sale, registration and stamp duty on the sale deed, legal fees paid specifically for the transfer, and any other expenditure incurred wholly and exclusively in connection with the transfer. NOT deductible: costs of acquiring the new asset, income tax paid, GST (where applicable), and costs that are already deductible elsewhere in the return.

Step 6: Compute the Net Capital Gain

The resulting figure is the Net Capital Gain before exemptions. Apply applicable exemptions (Section 54, 54EC, 54F) to arrive at the Taxable Capital Gain. Apply the tax rate: LTCG at 12.5% or 20% with indexation (property transitional option) or slab rate (STCG on most assets other than listed equity).

Special Cases in Capital Gain Computation

Inherited and Gifted Assets — Cost and Holding Period

For assets received by way of inheritance (on death of the previous owner) or gift (from specified relatives under Section 56), the capital gain computation uses the previous owner's cost of acquisition as the cost. The holding period for determining STCG or LTCG includes the previous owner's holding period. This is one of the most favourable provisions in capital gains law — a long-held asset transferred as a gift or inherited can immediately be treated as LTCG qualifying if the combined holding period exceeds the threshold.

Assets Acquired Before 1 April 2001 (Pre-CII Base Year)

For assets acquired before 1 April 2001 (the base year when the current CII was set at 100), the cost of acquisition for computing indexed LTCG is the higher of: the actual purchase price, or the Fair Market Value as on 1 April 2001. Using the FMV as on 1 April 2001 is almost always significantly higher than the original purchase price for assets held that long — it dramatically reduces the taxable gain. A residential flat bought in 1985 for ?2 lakh that was worth ?25 lakh on 1 April 2001 uses ?25 lakh as the cost base (indexed forward to the year of sale) — not ?2 lakh.

Slump Sale of Business — Section 50B

When an entire business undertaking is transferred for a lump sum consideration without values being assigned to individual assets, it is a 'slump sale' under Section 50B. The capital gain is computed as: Sale Consideration minus Net Worth of the undertaking as per books. There is no indexation benefit on slump sales. If the undertaking has been held for more than 36 months, it is LTCG at 12.5% (post Budget 2024); if 36 months or less, STCG at slab rate.

Conversion of Capital Asset to Stock-in-Trade — Section 45(2)

When a capital asset (e.g., land) is converted from a capital asset to stock-in-trade for business purposes, capital gain is triggered at the time of such conversion — even though no actual sale has taken place. The capital gain is taxable in the year the stock-in-trade is actually sold, but computed based on the FMV at the date of conversion.

Compulsory Acquisition — Section 45(5)

When a capital asset is compulsorily acquired by the government, the capital gain is taxable in the year the compensation is received — not in the year of acquisition. If additional compensation is received on appeal, it is taxable in the year it is received, with the same STCG/LTCG classification as the original compensation.

NRI Capital Gain Computation — Special Considerations

NRI capital gain computation has additional dimensions beyond the standard resident computation — DTAA treaty benefits, TDS at source deducted by the buyer, and FEMA repatriation considerations. Our TDS and tax liability advisory and DTAA advisory cover these NRI-specific dimensions in detail.

• DTAA reduction of tax rate: Under certain DTAAs (Mauritius, Singapore for pre-2017 investments), capital gains on Indian assets may be taxable only in the treaty country — eliminating India tax entirely.
• Buyer TDS before payment: The buyer deducts TDS under Section 195 before paying the NRI seller. TDS is typically on the full consideration — creating excess TDS where the NRI claims exemptions. The NRI files an ITR to claim the refund.
• First Proviso to Section 48 — no indexation for NRI: For NRI sellers, capital gains on Indian rupee-denominated assets are computed in foreign currency using the prescribed computation — involving the RBI reference rate at the time of acquisition and sale.
• Section 115E — NRI special rates: An NRI can opt for Section 115E treatment — where all investment income and LTCG from specified assets are taxed at special flat rates (20% for LTCG) without basic exemption.

Historical Context — How Capital Gain Computation Law Evolved

The Cost Inflation Index (CII) was introduced in 1981 — initially with a base year of FY 1981-82 (CII = 100). The base year was subsequently shifted to FY 2001-02 (CII = 100) from Assessment Year 2018-19 — removing the need to track costs back to the 1980s and simplifying the computation for most assets, using the higher of actual cost or FMV as on 1 April 2001 as the base.

Budget 2018 introduced LTCG tax on listed equity shares (after 14 years of exemption since 2004) with the grandfathering provision. Budget 2023 removed LTCG indexation benefit for debt mutual funds bought after April 2023. Budget 2024 removed indexation for property (with transitional relief) and standardised LTCG at 12.5% across most capital asset categories — a fundamental simplification but one with significant tax impact for long-held assets.

How We Handle Capital Gain Computation — Our 6-Step Process

1. Asset Inventory and Classification — We begin by inventorying all capital assets sold during the financial year — property, shares, mutual funds, business assets, gold, and others. For each asset, we determine: the asset type (for holding period threshold); the date of acquisition (own purchase, inheritance, or gift); the original purchase price; and the date of sale.
2. Holding Period Computation and STCG/LTCG Classification — For each asset, we compute the holding period from acquisition date to sale date — using the correct acquisition date (including the previous owner's period for inherited/gifted assets). We classify each gain as STCG or LTCG based on the applicable threshold for the asset type.
3. Cost Determination — Pre-2001 FMV, Indexed Cost, and Special Rules — For pre-2001 assets: we use the FMV as on 1 April 2001 (from valuation report or historical data) as the cost base where it exceeds the actual purchase price. For all LTCG assets: we compute the indexed cost using the CII ratio. For inherited or gifted assets: we identify the previous owner's purchase price and apply the pre-2001 FMV rules where applicable.
4. Budget 2024 Dual Computation for Pre-July 2024 Property — For properties acquired before 23 July 2024, we prepare two parallel computations: (a) LTCG at 20% with indexed cost; (b) LTCG at 12.5% without indexation on the actual gain. We compare both and identify the lower tax option — and document the comparison for ITR filing.
5. Exemption Application and Net Taxable Gain — After computing the gross LTCG, we apply applicable exemptions — Section 54 (residential house reinvestment), Section 54EC (NHAI/REC bonds), Section 54F (other long-term assets). We compute the net taxable gain after exemptions and the tax thereon.
6. Set-Off, Carry Forward, and ITR Filing — We apply the capital loss set-off — STCL against STCG and LTCG; LTCL against LTCG only. We compute the unabsorbed losses eligible for carry forward. We ensure the NRI ITR or resident ITR is filed by the due date to preserve the carry-forward benefit.

Why N D Savla & Associates for Capital Gain Computation Services

• Complete asset coverage in one engagement. Capital gain computation covers not just property — it covers shares, mutual funds, business assets, gold, foreign assets, and any other capital asset sold during the year. We compute gains for all asset categories in a single integrated engagement — ensuring the set-off of losses between asset categories is correctly applied and the Schedule CG in the ITR is complete and accurate.
• Pre-2001 FMV expertise. The FMV as on 1 April 2001 is the single most important number for pre-2001 asset computations — and it must be from a registered valuer for immovable property. We coordinate registered valuer reports where needed and use verified historical data for other asset types.
• Budget 2024 transitional computation as standard. For every pre-July 2024 property transaction, we prepare the dual computation — 12.5% without indexation and 20% with indexation — and identify the optimal option. This is a standard part of every property capital gain engagement from FY 2024-25 onwards.
• NRI capital gain with DTAA integrated. For NRI sellers, the computation includes both the domestic tax liability and the DTAA treaty analysis — identifying treaty benefits, advising on Section 197 lower TDS certificate applications, and coordinating the DTAA credit claim in the ITR.
