A bonus issue sounds like a gift — the company is giving you free shares. But the mechanics are more nuanced than that. Understanding exactly how a bonus issue works, where the shares come from, and what it signals about the company helps you read this corporate action correctly.
What Is a Bonus Issue?
A bonus issue (also called a scrip dividend or capitalisation issue) is a corporate action where a company issues additional shares to existing shareholders at no cost, by converting accumulated free reserves (retained earnings, general reserves) into paid-up share capital.
No cash changes hands — the company doesn't receive money from you, and you don't receive money from the company. The reserves on the balance sheet shift from "free reserves" to "paid-up capital."
Definition block: A bonus issue is the conversion of a company's accumulated retained earnings into additional shares distributed free to existing shareholders. For every N shares held, shareholders receive M additional shares based on the bonus ratio. Share price adjusts downward proportionally, keeping total market capitalisation unchanged. For Indian companies, bonus issues require sufficient free reserves under SEBI's ICDR Regulations.
How a Bonus Issue Works — Step by Step
| Step | What Happens |
|---|---|
| Board approval | Company board approves the bonus ratio and record date |
| SEBI/exchange filing | Intimation filed with NSE/BSE; ex-date set |
| Ex-date | Last date to buy shares and qualify for the bonus |
| Record date | Company checks demat records to identify eligible shareholders |
| Allotment | Bonus shares credited to demat accounts (usually within 2–3 days of record date) |
| Price adjustment | Exchange adjusts the stock price downward by the bonus ratio |
Real example from NSE: Sangam Finserv Ltd issued a 4:1 bonus with record date February 7, 2025. An investor holding 100 shares at ₹100 each (₹10,000 total) received 400 additional shares. Post-bonus: 500 shares at ₹20 each = ₹10,000. Total value: unchanged.
Bonus Issue Ratios — What They Mean
| Ratio | Additional shares per 1 held | Total shares after | Price adjustment |
|---|---|---|---|
| 1:1 | 1 | Doubles (2×) | Halves |
| 2:1 | 2 | Triples (3×) | Divides by 3 |
| 3:1 | 3 | 4× | Divides by 4 |
| 4:1 | 4 | 5× | Divides by 5 |
A 4:1 bonus (like Sangam Finserv) is generous — it signals the company has accumulated substantial reserves relative to its paid-up capital base. A 1:1 bonus is more common and signals moderate reserve accumulation.
The Balance Sheet Mechanics
The accounting entry for a bonus issue:
Debit: Free Reserves / Retained Earnings
Credit: Paid-up Share Capital
What this means: The company hasn't created new value — it has reclassified existing value. The reserves that belonged to shareholders (as retained earnings) are now formally represented as additional shares. The total shareholders' equity stays the same.
Why this matters for investors: A company can only issue bonus shares if it has sufficient free reserves. You cannot issue bonus shares from revaluation reserves (gains from re-marking asset values upward). This is a SEBI requirement. So a bonus issue is evidence that the company has genuinely accumulated profits over time — not just paper gains.
According to BSE India, listed companies must comply with SEBI's ICDR Regulations for bonus issues, which require that the reserves being capitalised are actual free reserves and not revaluation or unrealised reserves.
What a Bonus Issue Signals
What it confirms:
- The company has accumulated real free reserves (profitable track record)
- The board believes in shareholder reward without depleting cash (unlike dividends)
- Share price has often risen to a level where affordability is a concern — bonus improves liquidity
What it does not confirm:
- That the company will continue performing well
- That current quarter earnings are healthy
- That management is confident in near-term outlook
A company can issue a bonus from historical reserves while the current business is under pressure. The reserves reflect the past — not necessarily the future.
Bonus Issue vs Dividend — Key Difference
| Bonus Issue | Dividend | |
|---|---|---|
| What you receive | Additional shares | Cash |
| Company's cash | Unchanged | Reduces |
| Tax on receipt | None | Taxed as income |
| Tax on sale | Capital gain on ₹0 cost shares | Already taxed on receipt |
| Reserves | Reduce (capitalised) | Reduce (paid out) |
| Signal | Strong historical reserve accumulation | Current profitability confidence |
Key Takeaways
- A bonus issue gives you more shares, not more value — total investment stays the same on bonus date
- Shares are funded from the company's own free reserves, not from new cash
- A 4:1 bonus signals stronger reserve accumulation than a 1:1 bonus
- Bonus shares have ₹0 cost of acquisition — entire sale value is capital gain when sold
- A bonus issue reflects past profitability, not necessarily current business health
Before You Read Too Much Into a Bonus Issue
A bonus issue is a backward-looking signal — it tells you the company accumulated reserves. What you actually need to know is whether the business generating those reserves is still on track.
StockMirror's Earnings Quality signal tells you whether current profits are clean or driven by one-time items. Management Confidence shows whether the team running the company is genuinely confident right now — not just rewarding shareholders for what was built years ago.

Frequently Asked Questions
What is a bonus issue in India?
A bonus issue is when a company issues additional shares to existing shareholders for free, funded by converting accumulated reserves into paid-up share capital. In a 1:1 bonus, you receive 1 additional share for every 1 share held. Total investment value stays the same.
Is a bonus issue really free shares?
Not in value terms. New shares are created from the company's own reserves — money already belonging to shareholders. The share price adjusts downward proportionally. Your total holding value stays unchanged. It is free in the sense no cash leaves your pocket.
What is a bonus issue ratio?
The bonus ratio tells you how many additional shares you receive per share held. A 1:1 ratio means shares double. A 4:1 ratio — like Sangam Finserv in February 2025 — means 4 bonus shares per 1 held, turning every share into 5.
What is the tax on bonus shares in India?
Bonus shares are not taxed when received. The cost of acquisition is ₹0. When sold, the entire sale value is capital gain — LTCG at 12.5% (held 12+ months) or STCG at 20% (held under 12 months). Holding period starts from the bonus allotment date.
What is the difference between a bonus issue and a dividend?
A dividend pays cash from profits. A bonus issue gives additional shares from reserves — no cash outflow. Dividends are taxed as income on receipt. Bonus shares are not taxed on receipt but create capital gain on sale.
