Share Buybacks in India: Tender Offers, Tax & the Open-Market Phase-Out

You will usually meet a buyback as a notification from your broker. The company is offering a price higher than the screen price, the deadline is short, and every WhatsApp group is calling it free money. That is exactly when you need a calculation, not excitement.

Until a few years ago, Indian companies could choose between two routes for a buyback. They could send shareholders a fixed-price invitation (the tender offer — "tender" simply means you submit your shares for the company to buy back). Or they could ask a broker to quietly pick up shares from the open market on NSE and BSE.

SEBI phased out that open-market route after 1 April 2025. For any new buyback you see today, the route is almost certainly tender.

What a buyback actually is

Picture a small bakery owned by you and nine friends. Ten partners, one share each, all sharing the profits equally. The business has done well for years and has built up a healthy pile of cash sitting in its account.

Instead of opening a second outlet, you and the others vote to buy out three of the friends and cancel their shares. Now seven partners share the same profits. The three who left walk away with cheques drawn on the bakery's own account.

That is exactly what a corporate buyback does, at a much larger scale. Several large Indian companies, especially cash-rich IT services and consumer names, have returned thousands of crores to shareholders this way over the years. You can find any particular company's buyback history on its NSE or BSE corporate-action page.

The cash comes out of the company. The share count shrinks. Each remaining share owns a slightly bigger slice of the same business.

Two routes — one is still live

Historically, an Indian company could run a buyback in two ways. Both finished with shares cancelled and cash distributed, but the experience for a shareholder was very different.

For a 2026 retail investor, the tender route is the one that matters in practice. It is the only buyback where you, the shareholder, are formally invited to the table with a fixed price and a clear deadline.

How the tender route works

A tender buyback runs on a strict timetable set by SEBI. From announcement to cash credit, the whole sequence usually takes six to eight weeks.

• Step 1 · Board announcement

  The buyback is filed with the exchanges

  The board declares the buyback, the total size in rupees, the price per share, and the maximum number of shares being repurchased. The filing goes to NSE and BSE before any other channel.

• Step 2 · Record date

  The eligibility cut-off

  The company freezes the shareholder list on this date. Think of it as the class attendance sheet for that corporate action — if your name is on the list at end of day, you are in. Buying after the record date does not get you into this particular buyback.

• Step 3 · Entitlement ratio

  How many of your shares are guaranteed eligible

  The company tells each eligible shareholder how many shares they can tender as a guaranteed quota. A ratio of 1:14 means one share out of every fourteen you own qualifies. Anything you tender on top of that quota is accepted only if other shareholders do not tender their full portion. The shares that stay back sit untouched in your demat (your electronic share account, the equivalent of a bank account for stocks).

• Step 4 · Tendering window

  You place the order in your broker app

  A 5 to 10 day window opens in Zerodha, Groww, Angel One, ICICI Direct, and the other major brokers. You place a tender order for some or all of your eligible shares. No cash leaves your bank at this stage.

• Step 5 · Allotment and credit

  Accepted shares are cancelled; cash hits your bank

  Accepted shares are cancelled and the proceeds are credited to your bank account, typically within a week of the window closing. Any shares that were tendered but not accepted come back into your demat untouched.

One detail matters more than most retail investors realise. SEBI mandates that 15 percent of every tender buyback be reserved for small shareholders — defined as anyone whose holding is worth ₹2 lakh or less on the record date. For a retail investor with a modest parcel, that reserved tranche often produces an acceptance ratio two to three times higher than what large institutions receive.

What the old open-market route looked like

Under the old open-market route, the company skipped the formal invitation entirely. It appointed a registered broker, typically a big name like Kotak Securities or ICICI Securities, and instructed them to buy shares on NSE and BSE at or below a pre-announced ceiling price.

From a retail investor's point of view, almost nothing visible changed. You would see a few extra buy orders hit the market each session, often near the close.

If you sold during that buyback period, your shares might have ended up cancelled by the company, or they might have ended up in another investor's demat. There was no way to tell which.

The company kept buying until one of three things happened. It spent the full announced rupee amount, it bought the maximum quantity allowed, or the six-month regulatory window expired. SEBI later closed the route to make buybacks more transparent and more even-handed for small shareholders.

What it means for your tax

Until October 2024, many retail investors treated buybacks as easy arbitrage. The headline premium hit your bank intact, and the math was simple.

Before the change, the company paid a 23.296 percent buyback tax under Section 115QA and shareholders received clean money. That arrangement made buybacks more tax-efficient than dividends for most retail holders.

The Finance (No. 2) Act, 2024 changed the rule from 1 October 2024. The entire buyback amount is now treated as deemed dividend in the shareholder's hands and taxed at slab rates — your personal income-tax bracket — exactly like salary or interest income. The buyback tax on the company has been removed.

For anyone in the 30 percent bracket, this is a meaningful shift. As a rough illustration only, a ₹50,000 tender that would once have arrived intact may now leave roughly ₹35,000 after slab tax. Add applicable surcharge and cess, and the real after-tax number can be a little lower; the exact figure depends on your total income and other deductions.

Your original cost of acquisition becomes a notional capital loss that you can set off against future capital gains. That partly softens the blow over time, but only if you actually have those future gains to set it against.

Why companies run buybacks

There are three honest reasons a board decides to buy back its own shares. The first is the cleanest: free reserves — cash and accumulated profits that the company is allowed to distribute — with no good way to redeploy them. A profitable, cash-rich business often generates more cash every quarter than it can sensibly reinvest at its usual rate of return.

The second reason is signalling. Management who genuinely believe the stock is undervalued can put company money where their words are. A buyback at a 15 percent premium effectively says, "we think the market has this wrong"; it is a more credible signal than any press release.

The third reason is less honest. Buybacks mechanically reduce the share count, which mechanically lifts earnings per share (EPS) — the company's profit divided by the number of shares outstanding. EPS is tied to executive bonuses at many large companies, so some buybacks are essentially executives quietly writing themselves a bigger paycheck with shareholder cash.

The distinction matters when you read a buyback announcement. A small cash-rich company with no good projects buying back stock is a healthy return of capital. A leveraged company taking on debt to buy back stock and lift EPS is something quite different.

The price chart will not tell you which one you are looking at. The cash flow statement and the debt schedule will.
