What is LTCG & STCG Calculator (Equity)?
▾
In corporate treasury and private wealth management, managing the tax drag on equity investments is critical for maximizing net-of-tax returns. This calculator is designed for finance professionals, corporate treasurers, and high-net-worth entrepreneurs to model the tax impact of liquidating listed equity shares and equity-oriented mutual funds under the Indian Income Tax framework. It distinguishes between Short-Term Capital Gains (STCG) and Long-Term Capital Gains (LTCG) based on holding periods, allowing corporate strategists to optimize exit timings and preserve capital. The critical dividing line is the 12-month holding period. Assets liquidated within 12 months trigger STCG, which is taxed at a flat rate of 20% (for transactions executed on or after July 23, 2024, up from 15% previously). Holding the assets beyond 12 months transitions the gains to LTCG, taxed at a more favorable rate of 12.5% (previously 10%) on gains exceeding the ₹1,00,000 statutory annual threshold. This transition threshold is a vital lever for portfolio managers deciding whether to hold a position to achieve long-term tax status or execute a short-term tactical exit. For vintage positions acquired prior to January 31, 2018, the tool integrates the grandfathering framework, adjusting the cost of acquisition to the Fair Market Value (FMV) of that date to protect historical gains from retroactive taxation. Furthermore, the tool accounts for the landmark changes introduced in the Union Budget 2024, ensuring compliance and accurate forecasting for the transitional financial year FY 2024-25. It serves as an indispensable tool for corporate treasury forecasting, cash flow management, and post-tax ROI assessments.

Formula
▾
STCG Tax = STCG Amount × Tax Rate (20% post-July 23, 2024 / 15% pre-July 23, 2024); Adjusted Purchase Cost (for pre-2018 assets) = Max(Actual Purchase Price, FMV as of Jan 31, 2018); LTCG = Sale Proceeds - Adjusted Purchase Cost; Taxable LTCG = Max(0, LTCG - ₹1,00,000); LTCG Tax = Taxable LTCG × Tax Rate (12.5% post-July 23, 2024 / 10% pre-July 23, 2024)Variable Legend

How to LTCG & STCG Calculator (Equity)
▾
- 1Classify the asset holding period: Compare the acquisition and disposal dates. If the holding duration is 12 months or less, categorize the transaction under Short-Term Capital Gains (STCG). If it exceeds 12 months, classify it under Long-Term Capital Gains (LTCG).
- 2Apply the correct tax rate based on the execution date: Identify if the sale occurred before or after the Budget 2024 threshold (July 23, 2024) to apply the appropriate rate (15% vs 20% for STCG; 10% vs 12.5% for LTCG).
- 3Adjust the cost basis for legacy holdings: For assets purchased prior to January 31, 2018, apply the grandfathering rule by selecting the higher of the actual purchase price or the Fair Market Value (FMV) on January 31, 2018.
- 4Deduct the statutory exemption: For LTCG, pool all equity-oriented long-term gains across the portfolio for the fiscal year and apply the ₹1,00,000 annual tax-free threshold.
- 5Factor in Transaction Taxes (STT): Ensure the transactions were routed through a recognized stock exchange where Securities Transaction Tax (STT) was paid, which is a prerequisite for these preferential tax rates.
- 6Compute net capital gains after set-offs: Set off short-term losses (STCL) against both short- and long-term gains, while long-term losses (LTCL) are strictly restricted to offsetting long-term gains.
- 7Calculate final tax liability: Apply the flat tax rates plus the applicable 4% health and education cess to determine the net tax outflow for corporate cash flow planning.
Worked Examples
▾
Taxed at the new 12.5% rate as the sale occurred post-July 23, 2024.
The holding period is approximately 23 months (greater than 12 months), qualifying it as LTCG. Because the transaction was executed in October 2024, the revised rate of 12.5% applies. The first ₹1,00,000 is tax-exempt, leaving ₹6,00,000 taxable. The base tax is ₹75,000, and adding the 4% cess yields a total cash outflow of ₹78,000.
No statutory exemption is available for short-term gains.
Since the holding period is under 12 months (6 months) and the liquidation occurred after the July 23, 2024 budget, the revised 20% STCG rate applies. The entire gain of ₹2,50,000 is taxable at 20%, resulting in a base tax of ₹50,000. Including the 4% cess, the total liability is ₹52,000.
Sale occurred before July 23, 2024, so the old 10% LTCG rate applies.
The grandfathering clause adjusts the cost of acquisition to the higher of actual cost (₹150) or Jan 31, 2018 FMV (₹400). The total adjusted cost is ₹8,00,000. Selling at ₹19,00,000 generates a gain of ₹11,00,000. Subtracting the ₹1,00,000 exemption leaves ₹10,00,000 taxable at 10%, resulting in a ₹1,04,000 tax liability with cess.
Gains fall entirely within the annual ₹1,00,000 tax-free bracket.
The holding period exceeds 12 months, classifying the profit as LTCG. Since the total long-term gains for the fiscal year are under the ₹1,00,000 threshold, no tax is due, highlighting the utility of annual tax-harvesting strategies.
Real-World Applications
▾
Corporate treasurers designing cash flow models and evaluating the tax drag on liquidating corporate reserves held in equity mutual funds.
Family offices optimizing the timing of large-scale equity portfolio liquidations to minimize the tax impact under the new post-Budget 2024 rates.
Chartered Accountants preparing corporate tax filings and verifying the Schedule CG calculations against broker-provided transaction statements.

Special Cases
▾
Capital Gains in Mergers, Acquisitions, and Share Swaps
In corporate restructuring, share swap arrangements often occur during mergers or acquisitions. Generally, these swaps do not trigger immediate capital gains tax for the shareholder, as the cost of acquisition of the original shares is transferred to the newly acquired shares. The holding period is also cumulative, dating back to the original purchase, which helps corporate investors preserve their long-term tax status.
Taxation of Arbitrage Funds as Equity
Corporate treasuries seeking low-risk cash equivalents often utilize arbitrage mutual funds. Because these funds maintain equity exposure of 65% or more through simultaneous buy-sell transactions, they are legally classified as equity funds for tax purposes. This allows corporate cash managers to enjoy the lower 12.5% LTCG rate (after 12 months) instead of the higher corporate income tax slab rates that apply to standard debt instruments or fixed deposits.
NRI and Foreign Portfolio Investor (FPI) Tax Implications
For Non-Resident Indians (NRIs) and foreign corporate entities, tax is deducted at source (TDS) at the time of redemption by the fund house or broker at the highest applicable rate (20% for STCG, 12.5% for LTCG). Unlike domestic corporate investors who pay tax at the time of filing, foreign entities experience an immediate cash flow impact upon liquidation, making precise tax forecasting essential for cross-border capital repatriation.

Frequently Asked Questions
▾
How do the Budget 2024 amendments affect corporate treasury investments in equity?
The Union Budget 2024 substantially altered the tax landscape for equity investments. For any transactions executed on or after July 23, 2024, the STCG rate has increased from 15% to 20%, while the LTCG rate rose from 10% to 12.5%. This shift demands a strategic review of corporate treasury exit plans, as the tax drag on short-term liquidations has increased by 5 percentage points. Treasurers must now factor these higher rates into their net-of-tax yield models.
Can a corporate entity claim the ₹1 lakh annual LTCG exemption?
Yes, the ₹1,00,000 annual exemption on long-term capital gains under Section 112A is available to all categories of taxpayers, including corporate entities, partnership firms, and individual investors. This exemption applies to the aggregate long-term capital gains realized across all equity shares and equity-oriented mutual funds within a financial year. To maximize tax efficiency, corporate treasurers often plan partial redemptions across multiple fiscal years to utilize this threshold.
How does the grandfathering provision protect legacy corporate holdings from retrospective taxation?
The grandfathering provision, introduced when LTCG on equity was restored in 2018, ensures that gains accrued prior to February 1, 2018, remain tax-exempt. The acquisition cost for assets purchased before this date is adjusted to the higher of the actual purchase cost or the Fair Market Value (FMV) on January 31, 2018. This mechanism ensures that only the appreciation occurring after January 31, 2018, is subjected to the LTCG tax rate when liquidated today.
What are the specific rules for setting off business capital losses against equity gains?
Under Indian tax laws, short-term capital losses (STCL) are highly flexible and can be set off against both short-term and long-term capital gains. Conversely, long-term capital losses (LTCL) are highly restrictive and can only be set off against long-term capital gains. Neither type of capital loss can be set off against other heads of business income, such as active business profits or salary, though unabsorbed losses can be carried forward for up to eight assessment years.
How are equity-based ESOPs and RSUs taxed upon liquidation for corporate executives?
Equity-settled compensation is subject to a dual-stage taxation process. First, at the time of exercise, the difference between the fair market value and the exercise price is taxed as a perquisite (salary income) at the executive's slab rate. Second, when the executive subsequently sells the shares, the FMV on the exercise date acts as the new cost basis, and the gains are taxed as LTCG or STCG depending on whether the holding period from the exercise date exceeds 12 months.
How does the First-In, First-Out (FIFO) method affect systematic corporate investments (SIPs)?
For systematic investment plans (SIPs) or multi-tranche corporate stock purchases, the tax department mandates the First-In, First-Out (FIFO) method to determine the holding period. This means that when a partial redemption is executed, the units or shares acquired earliest are assumed to be sold first. Corporate accountants must track each monthly SIP installment as an independent investment with its own specific cost basis and 12-month holding period to prevent compliance errors.
Why is the payment of Securities Transaction Tax (STT) critical for securing these tax rates?
The concessional tax rates for STCG (15%/20%) and LTCG (10%/12.5%) are strictly conditional upon the transaction being subject to Securities Transaction Tax (STT). For listed equity shares, STT must have been paid at both the time of purchase and sale, whereas for equity mutual funds, it must be paid at redemption. If a transaction occurs off-market or involves unlisted equities where STT is not applicable, the gains are taxed under different, often higher, tax regimes.
Common Mistakes to Avoid
▾
- !Failing to aggregate LTCG across all brokerage accounts and equity mutual funds, leading to an incorrect assumption that the ₹1,00,000 tax-free exemption applies per fund or per broker rather than per PAN.
- !Neglecting the grandfathering provisions for vintage stocks purchased before 2018, which results in overpaying taxes by using the historical low purchase price instead of the higher January 31, 2018 FMV.
- !Assuming that short-term capital losses can be offset against salary or business income to reduce overall corporate tax liability, whereas capital losses can only offset capital gains.
- !Miscalculating the holding period of SIP investments by treating the entire fund balance under a single purchase date rather than evaluating each monthly installment on a First-In, First-Out (FIFO) basis.
Pro Tip
Implement systematic tax-gain harvesting before the end of every fiscal year. By selectively liquidating and immediately reinvesting equity assets to realize up to ₹1,00,000 of long-term capital gains annually, you can step up your portfolio's cost basis tax-free. Over a multi-year horizon, this strategy systematically reduces future taxable gains, preserving corporate liquidity and boosting net-of-tax portfolio yields.
Did you know?
Did you know that when India abolished the LTCG tax on equities in 2004 to stimulate capital markets, it introduced the Securities Transaction Tax (STT) as an alternative, friction-free revenue collector? When the government reintroduced the LTCG tax in 2018 due to fiscal requirements, they kept the STT in place. This dual-taxation structure means that modern corporate investors pay transaction taxes on every trade while still being subject to capital gains tax upon liquidation.
