Bonus share is a free additional share that a company gives to its existing shareholders, issued out of its accumulated reserves instead of cash. If you already own shares in a company, a bonus issue means more shares land in your demat account without you paying a single rupee — but as we'll explain below, "free" doesn't automatically mean your investment is worth more the day after.

We've tracked bonus issues on companies our readers hold — including the recent LIC bonus issue with a record date of 29 May 2026 — and the most common mistake beginners make is assuming a bonus announcement is pure upside. It isn't. This guide walks through exactly how the process works, why companies issue extra stock this way, what happens to your money on paper, and how it's taxed in India.

DefinitionWhat Is a Bonus Share, Exactly

A bonus share is an additional equity share issued to existing shareholders at no extra cost, funded by converting a company's free reserves or securities premium into share capital. Instead of paying that accumulated profit out as a cash dividend, the company "capitalises" it — turning retained earnings into new shares distributed to whoever already holds stock on the record date.

The key thing to understand upfront: this doesn't create new wealth out of thin air. The company's overall market value (market capitalisation) stays roughly the same immediately after the issue. What changes is the number of shares that value is divided across, and the price per share adjusts downward to match.

MechanicsHow a Bonus Share Issue Actually Works

The mechanics behind a bonus issue happen in a specific sequence, and understanding this order helps explain why the share price moves the way it does:

1. Board approval — The company's Board of Directors proposes the issue, usually citing healthy free reserves and a desire to reward long-term shareholders.
2. Shareholder approval — For most companies, this needs to be ratified at an AGM or through an EGM/postal ballot, depending on the company's structure.
3. Regulatory filing — The ratio and intended record date are disclosed to the exchanges (NSE/BSE) under SEBI's Listing Obligations and Disclosure Requirements (LODR).
4. Record date is fixed — This is the date the company's shareholder register is checked to determine who qualifies.
5. Capitalisation of reserves — Free reserves or securities premium on the balance sheet are converted into paid-up equity capital.
6. Allotment and credit — New shares are credited directly to eligible shareholders' demat accounts, typically within about 15 days of the record date, according to Bajaj Finserv's investor education material.

Because this whole process expands the number of outstanding shares without changing the underlying business value, the exchange automatically adjusts the stock's trading price downward on the ex-date to reflect the new share count.

RationaleWhy Do Companies Issue Bonus Shares

At first glance, giving away free shares sounds like the company is losing something. In accounting terms it isn't — reserves simply move from one part of the balance sheet to another. So why bother? A few real reasons come up again and again:

• Signalling confidence — Often read by the market as a signal that management is confident about future earnings, since you generally don't capitalise reserves if you expect a rough few years ahead.
• Improving liquidity — A high stock price with relatively few shares outstanding can feel "expensive" and trade thinly. More shares at a proportionally lower price can improve daily volumes.
• Rewarding shareholders without a cash outflow — Unlike a dividend, this doesn't require an actual cash payout, which matters for capital-intensive businesses preserving cash for expansion.
• Optically resetting the share price — Bringing the per-share price down can make a stock feel more accessible, even though fundamentals haven't changed.

We'd treat any such announcement as one data point, not a standalone reason to buy. One from a company with weak or declining free reserves is a very different story than one from a company with a genuinely strong balance sheet — the ratio and the underlying financial health matter far more than the announcement itself.

RatiosBonus Share Ratios Explained With Examples

Every issue is announced with a ratio, written as new shares : existing shares. This ratio tells you exactly how many additional shares you'll receive for every share you already hold.

Real ratios vary widely by company. According to reporting on India's 2026 corporate actions, Foce India approved a 7:5 bonus issue with a March 2026 record date — meaning shareholders received 7 new shares for every 5 they held, a less common but perfectly valid ratio structure.

TimelineRecord Date, Ex-Date, and Credit Date

Getting these three dates confused is the single most common reason beginners miss out on an issue they were expecting. Here's what each one means:

• Announcement date — When the company first informs the exchanges about the planned issue and ratio.
• Record date — The specific date the company checks its shareholder register. Only investors holding shares in their demat account on this date qualify.
• Ex-date — Under India's T+1 settlement cycle, this typically falls one trading day before the record date. Buy on or after the ex-date and you will not receive the extra shares, even though you technically own the stock.
• Credit date / allotment date — When the shares actually show up in your demat account, usually within roughly 15 days of the record date.

Worked ExampleReal Example: How Your Holding Changes

Let's walk through actual numbers using a hypothetical based on real market patterns.

Where bonus shares can genuinely help you build wealth is if the improved liquidity, broader shareholder base, or the market's positive read on management's confidence leads to the stock re-rating upward over the following months — but that's a market outcome, not a guaranteed mechanical effect of the bonus itself.

We track bonus-adjusted holdings for our own model tracking sheet using exactly this 1:1 example, because it's the ratio most beginners encounter first and the easiest to sanity-check by hand before trusting any calculator.

ComparisonBonus Shares vs Stock Split vs Dividend

These three terms get mixed up constantly, and understanding the distinction is genuinely useful, not just trivia.

A bonus issue capitalises reserves into new shares, while a stock split simply divides each existing share into smaller units by reducing the face value — no reserves are touched at all. A cash dividend, by contrast, actually puts money in your bank account and is taxed as income in the year you receive it.

TaxationTax Treatment of Bonus Shares in India

Bonus shares themselves are not taxed at the time of allotment — you don't owe anything simply for receiving them. Tax only becomes relevant when you eventually sell them, and the calculation has one important quirk:

• Cost of acquisition is treated as zero for these shares specifically, since you paid nothing for them.
• When you sell, the entire sale price becomes your capital gain, not just the appreciation over a purchase price.
• Holding period is calculated from the date of allotment, not from when you bought the original shares.
• If held for more than 12 months from allotment, gains qualify for long-term capital gains (LTCG) treatment; if sold within 12 months, they're taxed as short-term capital gains (STCG).

This zero-cost-basis rule genuinely surprises a lot of investors at tax filing time. If you're preparing your return around this, our ITR filing deadline guide covers the broader filing calendar, and understanding how circuit breakers affect trading is useful background if you're active around ex-dates when volatility can spike.

PitfallsCommon Mistakes Beginners Make

• ✕Assuming the announcement makes you instantly richer. As shown in the example above, your total holding value is essentially unchanged on day one — only the share count and price per share move.
• ✕Buying on the record date instead of before the ex-date. Because of settlement timing, you must own the stock before the ex-date, which typically falls a day earlier.
• ✕Confusing bonus shares with a stock split. They look similar on the surface (more shares, lower price) but work through entirely different accounting mechanisms.
• ✕Chasing stocks purely because free shares were announced. The ratio alone tells you nothing about whether the underlying business is fundamentally sound — always check the company's reserves, earnings trend, and overall financial health first.
• ✕Forgetting the zero-cost-basis rule at tax time, which can result in a much larger taxable gain than investors expect when they eventually sell.
