Buyback and tender offers on Zerodha

A share buyback (also called a share repurchase) is a corporate action where a company purchases its own shares from existing shareholders, reducing the total shares outstanding. In India, listed companies can conduct buybacks through two routes: the tender offer route (through the exchange platform) and the open market route (through the secondary market). Zerodha facilitates shareholder participation in tender offer buybacks through Kite .

Tender offers are distinct from open market buybacks: in a tender offer, the company announces a buyback price, a buyback period, and invites shareholders to tender their shares at the buyback price or below. Shares tendered at or below the final buyback price are accepted (subject to the company’s acceptance ratio). The open market buyback does not require any action from individual shareholders; the company buys shares from the exchange like any other buyer.

Regulatory framework

SEBI (Buy-Back of Securities) Regulations, 2018

Buybacks in India are governed by the SEBI (Buy-Back of Securities) Regulations, 2018 (replacing the earlier 2013 regulations). Key provisions:

• Maximum buyback size: A company can buy back up to 25% of its total paid-up share capital and free reserves in a single financial year (increased from 10% via a special resolution, or 10% via a board resolution).
• Sources of funds: Buybacks must be funded from free reserves, securities premium, or proceeds of earlier issue (not borrowed funds).
• Tender offer vs open market: Companies with buyback size greater than 15% of paid-up capital must use the tender offer route.
• Mandatory escrow: Companies conducting tender offer buybacks must deposit 25% of the total buyback amount in an escrow account with a bank or in the form of a bank guarantee before the buyback opens.
• Post-buyback restriction: After a buyback, the company cannot issue fresh equity (other than ESOPs) for one year.

Exchange platform for tender offers

SEBI mandated exchange-based clearing for tender offer buybacks through Circular SEBI/HO/CFD/DIL2/CIR/P/2016/56. Both NSE and BSE provide a tender offer platform through their respective clearing corporations (NCL and ICCL), with settlement and share transfer handled by the clearing corporation.

Tender offer process on Zerodha

Eligibility

Shareholders who hold the company’s shares in their Zerodha demat account (at CDSL ) on the buyback record date are eligible to participate. Shares purchased after the record date are not eligible.

The buyback ratio is published by the company: it specifies the reserved portion for small shareholders (typically shareholders holding shares worth up to Rs 2,00,000 on record date) and the general category.

Tendering shares via Kite

Zerodha facilitates tender offer participation through the Kite platform’s corporate action section:

1. The investor logs in to Kite and navigates to the buyback section when an eligible buyback is active.
2. The investor enters the number of shares to tender (cannot exceed eligible quantity).
3. Zerodha submits the tender order to the exchange’s buyback platform on behalf of the investor.
4. The tendered shares are blocked in the demat account (an encumbrance is placed by CDSL); the investor cannot sell these shares during the tender period.
5. On acceptance day, the exchange/clearing corporation calculates the acceptance ratio based on total shares tendered vs total shares the company will buy back.
6. Accepted shares are transferred to the company; the buyback consideration is credited to the investor’s bank account within the stipulated settlement timeline.
7. Unaccepted shares are returned (the encumbrance is removed) from the demat account.

Tender price

Tender offer buybacks have a fixed buyback price announced in the offer document (Letter of Offer). All accepted shares receive the same buyback price regardless of when during the tender period they were submitted. Unlike open market buybacks where no investor action is needed, tender offer prices are typically at a premium of 10% to 30% above the pre-announcement market price.

Acceptance ratio and small shareholder reservation

SEBI mandates that at least 15% of the buyback size is reserved for small shareholders in tender offers. Small shareholders are those holding shares worth up to Rs 2,00,000 on the record date.

If the small shareholder category is undersubscribed, the unsubscribed portion is transferred to the general category. If oversubscribed, the acceptance ratio for small shareholders may exceed 100% (proportional allotment applies; maximum 100% of tendered shares accepted).

In large-cap buybacks where general category is heavily oversubscribed, acceptance ratios in the general category can be as low as 10% to 30%, while the small shareholder category may see 100% acceptance. Retail investors holding shares worth less than Rs 2,00,000 can participate in the more favourable small shareholder category.

Open market buyback

In open market buybacks, the company buys shares from the secondary market over a defined period. Shareholders do not need to take any specific action; they can sell shares at market prices and may indirectly benefit from the price support provided by the company’s purchases. Zerodha facilitates no special process for open market buybacks; any secondary market sale on Kite during the buyback period is handled as a regular CNC sell order.

Buyback tax treatment

Section 115QA, Buyback distribution tax (BDT)

Prior to October 2024, listed companies were liable to pay Buyback Distribution Tax (BDT) under Section 115QA at 23.296% (20% plus surcharge plus cess) on the distributed income (difference between buyback price and issue price). This tax was paid by the company, and the proceeds received by shareholders were exempt from tax in their hands under Section 10(34A).

The Finance (No. 2) Act, 2024 inverted this framework with effect from 1 October 2024, and the treatment has since moved through three distinct regimes. The dedicated entry Buyback taxation: the 2024 deemed-dividend reform sets out the full timeline, sections, and worked arithmetic; the summary follows.

From 1 October 2024 to 31 March 2026:

• Section 115QA buyback distribution tax on listed-company buybacks was abolished, so the company pays nothing on the distribution.
• Section 2(22)(f) deems the entire buyback consideration a dividend in the shareholder’s hands, taxed at the shareholder’s slab rate as income from other sources. There is no deduction for the cost of acquisition against this dividend.
• Section 46A was amended so the buyback consideration is deemed nil for capital-gains purposes. The full cost of the tendered shares therefore becomes a capital loss (short-term or long-term by holding period), carried forward up to eight assessment years and set off only against capital gains.
• The matching shareholder exemption under Section 10(34A) was withdrawn. The company deducts TDS at 10 per cent under Section 194 for resident shareholders.

So the post-October-2024 receipt is taxed as deemed dividend at slab rate, not as a capital gain. For shares tendered before 1 October 2024, the old Section 10(34A) exemption applied and the company bore the BDT.

From 1 April 2026, the Finance Act 2026 reverted buyback taxation to capital gains for consideration paid on or after that date, ending the deemed-dividend window. Confirm the regime applicable to the financial year of your tender, and for any sizeable amount consult a chartered accountant, since the deemed-dividend and capital-loss interaction is easy to mis-state.

Cost of acquisition for tendered shares

For tenders inside the deemed-dividend window (1 October 2024 to 31 March 2026), the cost of acquisition is not deducted from the dividend; Section 46A converts it into a capital loss. Where the capital-gains regime applies (before 1 October 2024, and again from 1 April 2026), the cost of the tendered shares is set against the buyback consideration, the holding period runs from the original purchase date to the buyback acceptance date, and for pre-January 2018 holdings the grandfathering rule for LTCG may apply (cost deemed as fair market value on 31 January 2018 if higher than actual cost).

Buyback arbitrage

A common strategy is to purchase shares of a company after a buyback announcement at the current market price (below the buyback price) and tender them in the buyback at the buyback price, earning the premium. The arbitrage profit equals the buyback price minus the purchase price minus transaction costs and taxes.

Risks of this strategy:

• Acceptance ratio risk: Only a portion of tendered shares may be accepted; unaccepted shares must be sold at the prevailing market price, which may have declined from the purchase price.
• Record date risk: Shares must be purchased before the record date (T+1 settlement; last purchase date is effectively the trading day before the record date).
• Price decline risk: If the company cancels or reduces the buyback size, the market price may fall sharply.
