The landscape for share buybacks in India has seen significant upheaval, with tax regulations undergoing three major overhahauls in just 18 months. These frequent changes have reshaped the financial implications for companies, their promoters, and individual investors alike. Understanding the nuances of each regime, especially the latest framework effective from April 1, 2026, is crucial for anyone involved in the Indian stock market.
What is a Share Buyback?
A share buyback occurs when a company repurchases its own shares from existing shareholders. This process can be executed through various mechanisms, including open market purchases, tender offers, or book-building. Companies often undertake buybacks to return surplus cash to shareholders, improve earnings per share by reducing outstanding shares, or boost shareholder value.
A Shifting Tax Landscape: Three Regimes
The tax treatment of share buybacks has been a moving target, evolving from a company-level levy to a deemed dividend approach, and now back to a capital gains framework.
Phase 1: Pre-October 2024
Before October 2024, the primary tax burden for buybacks fell on the company. Under Section 115QA of the Income-tax Act, 1961, companies were liable to pay a buyback tax at an effective rate of approximately 23.296%, which included surcharge and cess. During this period, the income generated from the buyback was largely exempt in the hands of the shareholders.
Phase 2: October 2024 – March 2026
A significant shift occurred on October 1, 2024, when the company-level buyback tax was abolished. The entire consideration received by a shareholder from a buyback was then treated as a deemed dividend under Section 2(22)(f) of the Income-tax Act. This regime created considerable tax distortions for investors, as the full buyback consideration was taxable as dividend income, without allowing for a deduction of the shares' acquisition cost. The acquisition cost was instead recognized separately as a capital loss, complicating tax calculations and often leading to a higher effective tax burden for shareholders.
For example, if an investor received ₹50 lakh from a buyback for shares originally purchased at ₹10 lakh, the entire ₹50 lakh was subject to tax as a deemed dividend. The ₹10 lakh acquisition cost was then treated as a separate capital loss, which might not be fully offset.
Phase 3: April 2026 Onwards
The latest iteration, introduced by the Income-tax Act, 2025, and effective from April 1, 2026, reverts buybacks to a capital gains framework. Under Section 69(1)(2), the taxable capital gain is now calculated as the buyback consideration minus the cost of acquisition. This approach aligns the tax treatment more closely with the economic reality of shareholders selling their shares back to the company.
Impact on Shareholders and Promoters
Under the current rules, non-promoter shareholders with listed shares may face a 12.5% long-term capital gains tax or a 20% short-term capital gains tax, depending on specific conditions. However, a key change in this framework is the introduction of an additional tax specifically targeting specified promoters.
This additional burden could result in an effective tax rate of around 22% for corporate promoters and up to 30% for non-corporate promoters, inclusive of applicable surcharge and cess. These changes underscore the critical importance of timing for any buyback transaction, as the specific date can materially alter the final tax outcome for all parties involved.
