What is a Bonus Share? Meaning, Types, Eligibility & Tax

Quick Summary

Bonus shares increase your holding without costing you anything extra. Here is what to know before the next bonus issue comes around.

• Meaning: Free extra shares issued from a company's reserves

• Common ratios: 1:1, 1:2, 2:1, decided by the board

• Eligibility: Must hold shares before the ex-date and record date

• Tax treatment: No tax on receipt, acquisition cost treated as zero

• Vs Rights Issue: Bonus shares are free, rights issue requires payment

• Data source: NSE/BSE corporate action filings

What Are Bonus Shares?

Bonus shares are additional equity shares a company allots to existing shareholders at no cost, funded by capitalizing free reserves or retained earnings instead of distributing that value as a cash dividend. The proportion of ownership stays the same immediately after allotment, since every shareholder receives new shares in the same ratio.

For example, Anand Rathi Wealth allotted bonus shares in a 1:1 ratio to shareholders holding stock as of the record date of June 3, 2026, funded through capitalisation of Rs 41.51 crore from its Retained Earnings, Securities Premium, and Capital Redemption Reserve accounts (Source: NSE corporate filing, June 4, 2026). A shareholder holding 100 shares before the record date received 100 additional shares at no cost.

Why Do Companies Issue Bonus Shares?

Companies choose bonus shares over a cash dividend for a few specific reasons.

• Preserve cash: Rewards shareholders without depleting funds needed for operations or expansion

• Improve affordability: Lower per-share price after the issue makes the stock accessible to more retail investors

• Boost liquidity: More shares in circulation generally means higher daily trading volume

• Signal confidence: A bonus issue often reflects management's confidence in future earnings and reserves strength

Foce India Limited approved a 7:5 bonus issue at its EGM on January 31, 2026, fixing March 2, 2026 as the record date, converting reserves directly into share capital while leaving underlying net worth unchanged (Source: NSE corporate filing, February 24, 2026).

Who Is Eligible for Bonus Shares?

Eligibility depends entirely on holding shares before two key dates: the ex-date and the record date.

Buying shares on or after the ex-date does not make an investor eligible, even if the purchase happens before the record date, since settlement under India's T+1 settlement cycle means ownership only transfers a day later. A new ISIN is typically not required for fully paid bonus shares, since they rank pari passu with existing shares and get credited directly to the same holding.

How to Calculate Bonus Shares

Calculating a bonus entitlement takes three steps.

1. Check the announced ratio. For example, a 1:2 ratio means 1 bonus share for every 2 held.

2. Count existing shares. Say an investor holds 300 shares.

3. Apply the ratio. 300 shares x (1/2) = 150 bonus shares. The investor's total holding becomes 450 shares after allotment.

For a 4:1 ratio and a starting holding of 10 shares, the calculation works out to 10 x 4 = 40 bonus shares, bringing the total to 50 shares, similar to Garware Technical Fibres' 4:1 bonus issue with a record date of January 3, 2025 (Source: NSE filing via Business Standard, December 2024).

Types of Bonus Shares: Fully Paid vs Partly Paid

Bonus shares fall into two categories, though one is far more common in India today.

Fully Paid Bonus Shares: Issued entirely from free reserves or retained earnings, requiring no further payment from shareholders. These shares are allotted in full and immediately carry equal status to existing holdings. The vast majority of bonus issues in India fall into this category.

Partly Paid Bonus Shares: Used to convert partly paid-up existing shares into fully paid-up shares by applying company reserves to cover the outstanding balance, rather than issuing entirely new shares. This type is rarely used today, since most companies issue only fully paid-up shares from the start.

Advantages of Bonus Shares

• No tax on receipt: Shareholders do not pay tax simply for receiving bonus shares

• Improved affordability: A lower per-share price after the issue can widen the investor base

• Higher liquidity: More outstanding shares generally increase daily trading volume

• No dilution of ownership percentage: Every shareholder gets the same proportional increase, so relative ownership stays unchanged

• Signals financial health: Reflects a company's confidence in its retained earnings and future prospects

Disadvantages of Bonus Shares

• No new capital for the company: Unlike a rights issue, a bonus issue raises no fresh funds for business use

• Reduced future dividend per share: With more shares outstanding, the same total dividend payout gets divided into smaller per-share amounts

• Possible short-term speculation: Stock prices sometimes see short-term hype around bonus announcements without underlying earnings support

• No guarantee of value creation: A bonus issue changes share count, not company value; the real benefit depends on the company's long-term earnings durability

Bonus Shares vs Rights Issue

Both are ways companies distribute value or raise resources through existing shareholders, but the mechanics are opposite.

The core difference comes down to funding: a bonus issue capitalizes existing reserves, while a rights issue brings in new money from shareholders willing to pay for additional shares.

Taxability of Bonus Shares

Bonus shares carry a specific tax treatment under Indian tax law that differs from regular share purchases.

On Receipt: No tax is payable when bonus shares are allotted, since they are not treated as income in the shareholder's hands.

Cost of Acquisition: For capital gains calculation, the acquisition cost of bonus shares is treated as zero, since no money was paid to acquire them. Understanding this alongside broader capital gains tax rules on securities helps in planning an exit strategy.

On Sale: Since the cost base is zero, the entire sale value counts as capital gain. If bonus shares are sold within 12 months of allotment, the gain is taxed as short-term capital gains at 20 percent. If held beyond 12 months, it qualifies as long-term capital gains, taxed at 12.5 percent on gains exceeding Rs 1.25 lakh in a financial year.

Holding Period Calculation: The holding period for bonus shares starts from the allotment date, not from when the original shares were purchased, which matters when deciding how long to hold before selling.

Bonus Issue vs Stock Split

Both increase the number of shares an investor holds and both lower the price per share, but the accounting treatment differs.

What Is a Stock Split? A stock split divides each existing share into multiple shares by reducing the face value proportionally, without touching reserves. A 1:2 split turns one Rs 10 face value share into two Rs 5 face value shares.

What Happens to Share Price? In both cases, the price adjusts downward in proportion to the increase in share count, while the investor's total investment value stays broadly the same immediately after the corporate action.

What It Means for You: Functionally, both increase share count and lower price per share without changing total investment value. A bonus issue tends to signal stronger reserve-driven confidence, while a stock split is usually a straightforward affordability and liquidity move.

How to Check the Bonus Shares List on NSE/BSE

Investors can track upcoming and recent bonus issues directly through official and broker-provided sources.

• NSE/BSE Corporate Announcements: Both exchanges publish real-time corporate action filings, including bonus ratio, record date, and ex-date, on their official websites

• Broker Corporate Action Pages: Most brokers maintain a running list of upcoming and recent bonus issues under a "Corporate Actions" section

• Company Investor Relations Pages: Listed companies post board resolutions and record date announcements directly

Checking this list regularly during earnings season, when boards commonly announce bonus ratios alongside quarterly results, helps investors stay ahead of ex-date deadlines. Tools like the Dhanarthi Screener can help track holdings and flag upcoming corporate actions across a portfolio in one place.

Conclusion

A bonus share issue increases the number of shares an investor holds without any cost, funded entirely by a company converting reserves into share capital. The real value lies not in the extra shares themselves, since total investment value stays broadly unchanged right after allotment, but in what the move signals about a company's reserves strength and management confidence.

Understanding the eligibility dates, the difference from a rights issue and a stock split, and the tax treatment on eventual sale helps investors make informed decisions rather than chasing short-term bonus announcement hype. Running a quick check through Dhanarthi's financial analysis tool can help evaluate whether a company's reserves and earnings genuinely support a bonus issue before reacting to the announcement.
