Share Buyback
A share buyback is when a company repurchases its own shares from existing shareholders, reducing the number of shares outstanding. In India, buybacks are governed by SEBI's Buy-Back of Securities Regulations and most now happen through the tender-offer route.
In a tender-offer buyback, the company fixes a buyback price (usually at a premium to the market price), a record date, and a total buyback size. Eligible shareholders tender their shares in a set window, and if more shares are tendered than the company will buy, acceptance is proportionate. A portion of every tender-offer buyback is reserved for small shareholders (holdings up to ₹2 lakh by market value on the record date), which is why small investors often get better acceptance ratios than large ones. SEBI has been phasing out the alternative open-market route, making the tender route the standard.
Companies buy back shares to return surplus cash, to support the stock when management believes it is undervalued, to improve per-share metrics like EPS and return on equity, or to raise promoter holding percentage without a purchase (the promoters simply don't tender). The signal is usually read as management confidence, but the details matter: a small buyback relative to market cap moves little, and a buyback funded by debt or done while the business is starved of investment deserves skepticism.
Tax has changed twice recently. From 1 October 2024, buyback proceeds were taxed in the shareholder's hands as dividend income at slab rates. From 1 April 2026, under the Finance Act 2026, they are taxed as capital gains instead — the price received minus the cost of the tendered shares, at 12.5% long-term (gains above ₹1.25 lakh a year, shares held over 12 months) or 20% short-term — and promoters who tender pay an additional levy that takes their effective rate to 30% (22% for promoter companies). Check the arithmetic before tendering: for some holders, tendering versus selling on market still flips after tax.

Common questions
How is a share buyback taxed in India now?
From 1 April 2026, under the Finance Act 2026, buyback proceeds are taxed as capital gains: the price received minus the cost of the shares tendered. For listed shares held over 12 months, long-term gains above ₹1.25 lakh a year are taxed at 12.5%; shares held for 12 months or less attract 20% short-term tax. This replaced the October 2024 rule that taxed the whole payout as dividend.
Do promoters pay a different tax on buybacks?
Yes. For buybacks from 1 April 2026, promoters who tender pay an additional tax on top of the normal capital-gains rate, which brings the effective rate on their gains to 30% for individual and other non-corporate promoters and 22% for promoter companies. The extra levy is meant to stop promoters taking money out through buybacks at a lower rate than dividends.
What is the acceptance ratio in a buyback?
It is the proportion of the shares you tender that the company actually buys. If a company is buying 10 lakh shares in a category and 50 lakh are tendered, the ratio is 20%, and the untaken shares go back to your demat account. The ratio is worked out separately for the small-shareholder reservation and the general category once the tender window closes.
Who counts as a small shareholder in a buyback?
A shareholder whose holding is worth ₹2 lakh or less at the closing price on the record date, measured on the exchange with the highest trading volume in the stock that day. SEBI's buyback rules reserve 15% of a tender-offer buyback, or the small shareholders' entitlement if that is higher, for this category.
How stocks tend to react
Buyback announcements often lift the stock in the short term, especially when the buyback price carries a meaningful premium and the size is significant relative to free float. The reaction tends to fade if acceptance ratios are expected to be low, and the stock frequently drifts back toward its own fundamentals once the tender window closes. Reaction depends heavily on size, premium, and whether the market reads it as confidence or as a lack of better uses for cash.
