A company announces bonus shares, and your share count increases. Another declares a dividend, and eligible shareholders receive a payment. A third offers existing investors the opportunity to buy additional shares.
These are examples of corporate actions. Each affects your investment differently, so understanding the announcement matters more than reacting to its headline. This guide explains what corporate actions are, how the common types work and what to check before deciding whether you need to respond.

What are corporate actions?
Corporate actions are events initiated by a company that affect its securities or the investors holding them. They may involve distributing profits, changing the number of shares, raising capital or restructuring a business.
For shareholders, the effect could be a cash payment, additional shares, an opportunity to invest more money or a change in the company they own.
A corporate action does not automatically make an investment more attractive. Its significance depends on what changes and why the company is making that change.
Key Takeaways
- Corporate actions are company decisions that can affect shareholders’ payments, shareholdings or ownership.
- Bonus issues and stock splits increase the number of shares without automatically increasing shareholder wealth.
- Some actions apply automatically to eligible shareholders, while others require an application or participation decision.
- The ex-date, record date and participation deadlines serve different purposes and should be checked separately.
- Assess the action’s terms, the company’s reasons and the financial implications before making an investment decision.
How do corporate actions work?
The process varies with the action, but generally involves:
- Announcement: The company communicates the proposed action and its terms.
- Approvals: It obtains the board, shareholder or other approvals required for that action.
- Eligibility and deadlines: Relevant dates determine who qualifies and when any response is due.
- Implementation: Payments, share credits or changes to holdings take place under the announced terms.
A proposal being considered at a board meeting is different from an approved action with a confirmed schedule. Read subsequent announcements before treating the initial proposal as final.
Types of corporate actions
Corporate actions can be grouped by whether they take effect automatically or require a response from shareholders.
1. Mandatory corporate actions
These apply automatically to eligible shareholders without a separate participation decision. A stock split is one example. “Mandatory” refers to how the action applies to shareholders; the company must still obtain the required approvals.
2. Voluntary corporate actions
These allow eligible shareholders to decide whether to participate. For example, in a rights issue, you can choose whether to subscribe to additional shares. Participation requires following the process and meeting the deadlines specified in the offer.
3. Mandatory corporate actions with options
These apply to eligible shareholders but offer a choice in how the entitlement is received. The company’s announcement explains the available options, the response deadline and what happens if you do not make a selection.
Common corporate actions and their impact on shareholders
Some corporate actions put cash in your account, while others change your shareholding or require you to decide whether to invest more. Understanding the difference helps you assess what each announcement means for your money:
Dividends
A dividend distributes a portion of a company’s profits to eligible shareholders. A cash dividend provides a payment while leaving the number of shares held unchanged. For background on assessing dividend payments relative to a share’s price, read about how to calculate dividend yield.
Bonus shares
A bonus issue gives eligible shareholders additional shares without requiring payment. The company transfers eligible reserves into share capital, while the face value per share remains unchanged. Your share count increases, but that increase alone does not create additional wealth.
Stock splits
A stock split divides existing shares into more shares with a lower face value per share. Your proportional ownership remains unchanged. Unlike a bonus issue, a split does not transfer reserves into share capital.

Share prices adjust to reflect bonus issues and splits. The mechanical adjustment is separate from subsequent price movements caused by trading and changes in investors’ expectations. A lower price per share after a split therefore does not, by itself, mean that the company has become cheaper to own.

Rights issues
A rights issue offers existing shareholders the opportunity to buy additional shares in proportion to their holdings.
Participation requires a decision and payment. Depending on the offer terms, you may subscribe, sell or renounce the entitlement, or allow it to lapse.
Receiving a rights entitlement is different from receiving the new shares. You need to complete the subscription process to acquire shares through that entitlement.
If you do not participate while new shares are issued to others, your percentage ownership may decline. Review how the company intends to use the money before committing more funds.

Share buybacks
In a buyback, a company purchases its own shares. Under a tender offer, eligible shareholders can offer shares for sale through the specified process. Check the offer price, participation window and acceptance terms rather than assuming every share offered will be purchased.
The decision involves comparing the offer with your assessment of the investment and the consequences of selling.

Mergers and demergers
A merger combines businesses, while a demerger separates a business or undertaking into another entity. The approved scheme determines the effect on shareholders. This may include exchanging existing shares for shares in another company or receiving shares in a resulting company.
Read the scheme for the share entitlement, implementation conditions and treatment of fractional holdings, where applicable.

Ex-date and record date: What is the difference?
These dates help establish entitlement, but they have different functions.
| Date | What it means |
| Record date | The date used to identify eligible shareholders for the specified action |
| Ex-date | The date from which shares trade without the relevant entitlement |
| Payment or allotment date | The date associated with paying the dividend or allotting shares |
| Participation deadline | The last date to submit the required response for a voluntary action |
For ordinary exchange purchases, buying on or after the published ex-date does not carry the relevant entitlement.
Do not assume that the ex-date must always fall one working day before the record date. Current NSE records show many actions with both dates on the same day. Check the exchange announcement for the specific security and consider the applicable settlement schedule.
Eligibility also does not mean that a payment or share credit will arrive on the record date.

How to check corporate actions in India
Start with official announcements rather than relying only on alerts or social media posts.
- Exchange filings: Check the company’s announcements and the NSE corporate actions page.
- Company documents: Read the investor relations announcement, offer document or scheme, as applicable.
- Account records: Check your demat statement and bank transactions after implementation to confirm what you received.
NSE’s corporate action records include the purpose, ex-date and record date. Read the underlying announcement for conditions that a summary entry may not explain.

Tax implications of corporate actions in India
There is no single tax treatment for every corporate action. Dividends received from domestic companies are generally taxable in shareholders’ hands. Receiving a payment and selling shares are different events, so their treatment should be assessed separately.

For buybacks from 1 April 2026, the applicable provisions under the Income-tax Act, 2025 treat the difference between consideration and acquisition cost as capital gains; additional provisions apply to promoters.
Source: Income Tax Department, Section 69 of the Income-tax Act, 2025, as amended in 2026.
Keep acquisition records, allotment details and company communications. These help establish the facts needed to assess tax consequences when shares are sold or holdings are restructured.

What to check before a corporate action
An announcement is easier to assess when you focus on the decisions it creates:
- Purpose: Why is the company distributing cash, raising money or restructuring?
- Final terms: Has the action been approved, and are any conditions still outstanding?
- Eligibility: Which holdings qualify under the announced dates and terms?
- Required response: Do you need to apply, pay, tender shares or select an option?
- Financial effect: Will you receive cash, commit more money or change your ownership?
- Investment fit: Does your reason for holding the company still stand after the action?
Avoid treating a larger share count, a lower price per share or an announced payout as a complete investment case. Before responding, identify what changes for your holding and what remains dependent on the company’s future performance.
Conclusion
Understanding corporate actions helps you interpret company announcements and their effect on your investment. Different types of corporate actions can change your shareholding, provide a payment or require a participation decision. Check the terms, ex-date, record date and applicable taxes, then consider whether the change affects your reason for owning the shares. An announcement deserves attention, but your decision should rest on what it means for your money.
FAQs
What should I do if I do not receive a dividend or bonus shares?
Contact the company’s investor services team and its registrar and transfer agent, or RTA. Keep the announcement and account records available so they can investigate. If the complaint remains unresolved, use SEBI’s applicable grievance redressal process.
Can I sell my rights entitlement instead of subscribing?
SEBI’s investor guidance explains that shareholders can sell rights entitlements on the exchange. Check the offer terms and trading window, because the opportunity is time-bound.
Does an acquisition always change my shareholding?
No. The effect depends on the transaction structure. A company buying another business does not necessarily exchange or replace its own shareholders’ shares; check whether the announced terms include a change to your securities.
Are corporate actions good or bad for investors?
Corporate actions are not automatically good or bad. Their effect depends on the terms, the company’s reasons and your investment needs. Assess what changes for your holding, whether you need to commit money and how the action affects your reason for owning the shares.
Are bonus shares taxable in India?
Bonus equity shares received through a proportionate bonus issue are generally not taxable at allotment. However, selling them can attract capital gains tax. For newly allotted bonus shares, the acquisition cost is generally treated as nil for capital gains calculations. Their holding period starts from the bonus allotment date, rather than the purchase date of your original shares. The applicable tax treatment depends on the holding period and sale conditions.
