Capital Gains Tax on Unlisted Shares in India 2026: The 24-Month Rule and Why There's No STT Discount

By Nitish Bharadwaj · Published Sep 14, 2026 · 6 min

Unlisted shares need a 24-month holding period to qualify as long-term — double the 12 months for listed, STT-paid shares — and miss the concessional treatment on both sides of that line. Long-term gains are taxed at a flat 12.5% with no indexation, same as listed shares, but without Section 112A's ₹1.25 lakh exemption. Short-term gains skip the listed market's flat 20% rate and get added to income at slab rate, up to 30% plus surcharge and cess. ESOP shares carry a separate perquisite tax at exercise, before this capital gains math applies.

Buy shares in a private company — through an ESOP, a friends-and-family round, or one of the pre-IPO share platforms that have grown popular over the past few years — and the tax rules on selling them look similar to listed-market trading at first glance: short-term and long-term gains, a flat long-term rate, no indexation since 2024. Underneath, two differences change the actual bill: the holding period needed to count as long-term is twice as long, and neither side of that line gets the concessional treatment listed, STT-paid shares receive.

The 24-Month Line: Twice as Long as Listed Shares

Shares listed and traded on a recognised stock exchange need just 12 months to qualify as long-term. Unlisted shares — private company stock, ESOP shares before the company lists, or shares bought through an unlisted-share dealer — need 24 months. Sell at 23 months and the entire gain is short-term; hold one month longer and it shifts to the long-term regime instead. The clock starts from the date of allotment or purchase, not from any later listing event, so ESOP shares held two years before the company's IPO already qualify as long-term at listing, even though they were unlisted for the whole holding period. Our guide to ESOP taxation at exercise and sale covers the perquisite tax that applies separately, before this capital gains calculation even begins.

Why the ₹1.25 Lakh Exemption Doesn't Apply Here

Section 112A's annual ₹1.25 lakh LTCG exemption is written specifically for equity shares and equity mutual fund units on which Securities Transaction Tax has been paid — a condition only a recognised-exchange trade satisfies. Unlisted shares fall under the general Section 112 instead, which taxes the entire long-term gain at 12.5% from the first rupee. A ₹3 lakh long-term gain on listed shares is taxed on only ₹1.75 lakh after the exemption; an identical ₹3 lakh gain on unlisted shares is taxed in full. Our breakdown of the Budget 2024 capital gains changes covers how the 12.5% flat rate and the indexation removal came about — the rate is the same across listed and unlisted shares, but the exemption gap is what actually separates them.

The Bigger Gap Is on the Short-Term Side

Short-term gains on listed shares get their own concession — Section 111A's flat 20% rate — but only because STT was paid on the exchange trade. Unlisted shares never go through a recognised exchange, so no STT applies, and Section 111A's rate doesn't extend to them. A short-term gain on unlisted shares is simply added to total income and taxed at the applicable slab rate, which can run to 30% plus surcharge and cess for higher incomes — a meaningfully worse outcome than the flat 20% a listed-share seller pays on an identical gain. Anyone selling private company or pre-IPO shares within 24 months of buying them should model the deal at their marginal slab rate, not at the 20% figure they may be used to from listed-market trading. The same STT-driven logic shapes how rights issue shares are taxed depending on whether they're subscribed, renounced, or left to lapse, which is worth reading if you're weighing a similar decision on a listed holding.

A Worked Example

An employee exercises ESOP shares in a still-private company 30 months ago at a fair market value of ₹200 a share, and sells them today at ₹500 a share after the company lists. The holding period — 30 months, counted from exercise, not from listing — clears the 24-month threshold, so the ₹300-a-share gain is long-term. At 12.5% with no indexation and no ₹1.25 lakh exemption, tax works out to ₹37.50 a share, regardless of how modest the total sale is. Had the same shares been sold at 20 months instead, the identical ₹300-a-share gain would be short-term, taxed at the seller's slab rate — 30% plus surcharge and cess for a top-bracket taxpayer, more than double the long-term outcome.

What to Track Before You Sell

• Confirm the exact allotment or purchase date on the share transfer form or company register — the 24-month clock starts there, not on any later listing or demat conversion.
• If the shares came via ESOP, keep the exercise-date FMV valuation on record — it sets the cost base for this capital gains calculation and is distinct from the perquisite already taxed at exercise.
• Don't assume the ₹1.25 lakh exemption or the 20% STCG rate apply just because the shares eventually got listed — the rate depends on whether STT was actually paid on the specific transaction, not on the company's current listing status.
• Model a near-24-month sale at both the short-term slab rate and the long-term 12.5% rate before deciding whether to wait — the gap is often large enough to justify a short delay.

Unlisted shares have become far more common in ordinary portfolios — through ESOPs, pre-IPO platforms, and family businesses — without the tax rules around them getting nearly as much attention as listed-market trading. The math isn't complicated once the two differences are clear: a 24-month wait instead of 12, and no access to the concessional rates or exemption that make listed shares comparatively forgiving. Track the allotment date and, for ESOP shares, the FMV at exercise, and the rest of the calculation follows directly from there.
