Bonus issues, stock splits, and buybacks are common "corporate actions" that change the number of shares you hold or the cash in your account — but they're often misunderstood as automatically creating wealth. Here's what each one actually means, and how they're taxed.
Bonus Shares
A bonus issue is when a company allocates additional shares to existing shareholders, free of cost, in a fixed ratio (e.g., 1:1 means one extra share for every share already held), funded out of the company's reserves. After a bonus issue:
- The number of shares you hold increases proportionally
- The share price typically adjusts downward in proportion, so the total value of your holding immediately after the bonus issue is roughly unchanged
- Your original investment cost gets spread across the new (larger) number of shares for capital gains calculation purposes
The "benefit" of a bonus issue is often more about perception and liquidity (more shares at a lower price per share can make a stock more accessible to smaller investors) than an immediate increase in wealth — the pie is cut into more slices, not made bigger.
Stock Splits
A stock split divides each existing share into multiple shares of lower face value — for example, a 1:5 split turns one share with face value ₹10 into five shares with face value ₹2 each. Like a bonus issue, the total value of a shareholder's holding remains roughly unchanged immediately after a split; only the number of units and the price per unit change.
| Aspect | Bonus Issue | Stock Split |
|---|
| Source | Company's reserves converted to share capital | Existing share capital divided into more units |
| Face value | Unchanged | Reduced proportionally |
| Effect on shareholder | More shares, proportionally lower price, same total value | More shares, proportionally lower price, same total value |
Share Buybacks
A buyback is when a company repurchases its own shares from shareholders, reducing the number of shares outstanding. Shareholders can choose to tender (offer to sell) some or all of their shares in a buyback, typically at a premium to the prevailing market price.
⚠ Buyback taxation has changed: Under earlier rules, companies bore a buyback distribution tax and proceeds were tax-exempt for shareholders. Under rules effective from October 2024, buyback proceeds are taxed as deemed dividend income in the hands of the shareholder at slab rate, with the original cost of the shares potentially treated as a capital loss. Given how frequently these provisions have been revised, always verify the rules applicable for the relevant assessment year — see our
capital gains tax guide for related context — before participating in a buyback or relying on a particular tax treatment.
What This Means for Your Portfolio Tracking
When any of these corporate actions occur, your brokerage and demat statements will reflect the change in share count and adjusted cost basis automatically in most cases, but it's worth understanding why your holdings have changed even though "nothing happened" to the underlying value. For investors following the principles in our beginner's investing guide, the key takeaway is that these corporate actions are mechanical adjustments — they don't, by themselves, change the fundamental value of the business you own a share of, and shouldn't be confused with a return on investment.
Frequently Asked Questions
Does receiving bonus shares increase the value of my holding? ▼
Not directly. When a company issues bonus shares (e.g., 1:1, meaning one additional share for every share held), the number of shares you hold increases, but the company's overall market value doesn't increase simply because of the bonus issue — the share price typically adjusts downward proportionally, so the total value of your holding remains roughly the same immediately after the bonus issue. The benefit, if any, comes from increased liquidity and the company's underlying performance going forward, not from the bonus issue itself creating value.
How is a stock split different from a bonus issue? ▼
A stock split divides each existing share into multiple shares of lower face value (e.g., a 1:2 split turns one ₹10 face-value share into two ₹5 face-value shares), while a bonus issue allocates additional shares to existing shareholders out of the company's reserves without changing the face value. Both increase the number of shares outstanding and proportionally reduce the price per share, with the total value of a shareholder's holding remaining roughly unchanged immediately after the event. The practical difference lies in the accounting treatment (face value change vs reserves utilisation) rather than the immediate effect on shareholders.
How are share buybacks taxed for shareholders? ▼
Taxation of share buybacks has changed over time. Under earlier rules, companies paid a buyback distribution tax and the proceeds were exempt for shareholders. Under more recent rules (effective from October 2024), the buyback consideration received by shareholders is taxable as deemed dividend income at the shareholder's slab rate, and the original cost of acquisition of the shares tendered may be treated as a capital loss. Because these rules have changed and may change again, shareholders should verify the applicable provisions for the relevant assessment year before participating in a buyback.
