When a company buys back its own shares, it returns cash to shareholders by reducing the number of shares outstanding — the mirror image of issuing new stock. For Indian investors, a buyback announcement raises immediate, practical questions: should you tender your shares, what is the "acceptance ratio," how is the money taxed now that the rules have changed, and what is management really signalling? This guide answers each, and separates the genuine signal of a buyback from the noise around it.
This is an educational explainer on a corporate action, not advice on any specific buyback or stock.
By cancelling repurchased shares, a buyback shrinks the share count. If profits stay the same, earnings per share (EPS) rise mechanically because the same profit is divided among fewer shares:
A smaller share count also raises each remaining holder's proportional ownership of the company. This is why a buyback is a way of returning surplus cash to shareholders — an alternative to paying a dividend — while also signalling that management considers the stock worth buying at current prices.
The company offers to buy a fixed number of shares directly from shareholders, usually at a premium to the market price, as of a defined record date. Eligible holders can tender their shares into the offer. This is the route retail investors engage with most directly.
The company buys its own shares on the exchange over a period, at prevailing market prices, up to a maximum price and total amount. Individual shareholders don't actively "participate" — the company simply absorbs shares from the market.
For a tender offer, two dates matter: the record date (you must hold shares then to be eligible) and the tendering window (when you submit shares into the offer through your broker).
In a tender offer, a portion of shares is typically reserved for small shareholders, but the company still buys back only a limited quantity. If shareholders tender more shares than the company will buy, your shares are accepted proportionally — the acceptance ratio:
If the acceptance ratio is, say, 40%, then for every 100 shares you tender, roughly 40 are bought at the buyback price and the remaining 60 are returned to you, to be sold (or held) at the market price afterwards. The reserved quota for small shareholders often makes the effective acceptance ratio higher for retail than for large holders — a structural quirk worth understanding before you tender.
Buyback taxation in India was overhauled, effective from 1 October 2024. Under the earlier system, the company paid a buyback tax and the proceeds were tax-free in the shareholder's hands. Under the new regime, the buyback proceeds are treated as a deemed dividend and taxed in the shareholder's hands at their applicable slab rate, while the original cost of those shares is treated as a capital loss the investor can set off. This materially changed the after-tax appeal of tendering, especially for investors in higher tax brackets.
After October 2024, the headline buyback premium is no longer the whole story — the slab-rate tax on the proceeds can change whether tendering is actually worthwhile for you.
Because this is a recent and consequential change, confirm the current treatment for your situation with a SEBI-registered tax professional before deciding to tender.
The headline "40% premium" on a buyback rarely reaches your pocket in full — the acceptance ratio and the new tax both take a bite. Say you hold 100 shares bought at ₹500, and a tender offer is priced at ₹700 with a 40% acceptance ratio for small shareholders (illustrative; 30% tax slab):
| Step | Calculation | Result |
|---|---|---|
| Shares accepted | 100 × 40% | 40 shares at ₹700 |
| Buyback proceeds | 40 × ₹700 | ₹28,000 |
| Tax (deemed dividend, 30% slab) | 30% × ₹28,000 | −₹8,400 |
| Cost of those 40 shares | 40 × ₹500 | ₹20,000 → booked as capital loss to set off |
| Unaccepted shares | 60 shares | Return to your demat, often near market price post-record |
How to read it: only 40 of your 100 shares actually sold at the premium, and the ₹28,000 is taxed at your slab as a deemed dividend — so a headline "40% premium" nets far less after the acceptance ratio and post-October-2024 tax. The ₹20,000 cost of the accepted shares becomes a capital loss you can set off against other gains, which softens the blow for some investors but not all. The 60 unaccepted shares stay with you and often drift down once the buyback support is gone. This is why "is the premium worth it?" must be answered after acceptance ratio and tax, not from the headline number.
Buybacks are a regular feature of India's cash-rich sectors, especially IT services: large companies such as TCS and Infosys have returned substantial cash to shareholders through repeated buybacks over the years, typically via the tender route at a premium. The most important recent development, however, is regulatory: from 1 October 2024 the taxation shifted so that buyback proceeds are taxed as a deemed dividend in the shareholder's hands rather than via a tax paid by the company. That single change altered the long-standing "buybacks are more tax-efficient than dividends" logic — a reminder that with corporate actions, the tax framework can matter as much as the corporate decision itself.
