Alteration and Reduction of Share Capital and Buy-back for CA Inter
Updated 4 October 2026 · Fact-checked
Alteration (Section 61) changes the capital structure without cutting capital, mostly by a general meeting resolution if the articles allow. Reduction (Section 66) cuts capital by special resolution and needs Tribunal confirmation. Buy-back (Section 68) lets a company purchase its own securities if limits on size, debt ratio and procedure are met.
Understand Alteration and Reduction of Share Capital; Buy-back
A company's share capital can change over its life. The Act separates three situations, and exam questions test whether you can tell them apart.
Alteration (Section 61) changes the form or size of the capital, but money is not returned to members. A limited company with share capital can do it only if its articles authorise it, by altering the memorandum in a general meeting. The five alterations are: increase authorised capital; consolidate and divide shares into larger amounts; convert fully paid-up shares into stock and reconvert; sub-divide shares into smaller amounts; and cancel shares not taken or agreed to be taken by anyone.
Reduction (Section 66) is a real cut in capital, so creditors and members need protection. A company limited by shares or by guarantee with share capital may reduce capital by special resolution, but it is subject to confirmation by the Tribunal. It can extinguish or reduce liability on unpaid capital, cancel paid-up capital that is lost or unrepresented by assets, or pay off paid-up capital that is in excess of the company's wants.
Buy-back (Section 68) is the company purchasing its own shares or other specified securities. It must come out of free reserves, the securities premium account, or the proceeds of the issue of any shares or other specified securities, but not out of the proceeds of an earlier issue of the same kind. Because money leaves the company, the Act sets limits on size, debt, authorisation, timing and compliance.
A useful memory line: alteration needs the articles, reduction needs the Tribunal, buy-back needs the numbers (25% and 2:1).
Key rules to remember
- Sources of buy-back (Section 68(1))
- Free reserves | Securities premium account | Proceeds of issue of any shares or other specified securities
- No buy-back of any kind of shares or securities out of the proceeds of an earlier issue of the same kind. Free reserves includes securities premium account (Explanation II).
- Size limit (Section 68(2)(c))
- Buy-back ≤ 25% of (paid-up capital + free reserves)
- For buy-back of equity shares in a financial year, the 25% is applied to total paid-up equity capital in that year.
- Board-resolution limit (Section 68(2)(b) proviso)
- Buy-back ≤ 10% of (total paid-up equity capital + free reserves)
- If within this limit, Board resolution at a meeting is enough and no special resolution is needed. Articles must still authorise buy-back.
- Debt-equity test (Section 68(2)(d))
- (Secured + unsecured debts owed after buy-back) ≤ 2 × (paid-up capital + free reserves)
- The Act measures the debts owed after the buy-back against twice the paid-up capital and free reserves. It does not say that capital and reserves are reduced by the buy-back amount. The usual exam convention is to reduce them by the buy-back amount, unless the question says otherwise. The Central Government may notify a higher ratio for a class of companies.
- Time gaps and deadlines
- Complete within 1 year; no new offer within 1 year of closure of previous offer; destroy securities within 7 days; no further issue of same kind for 6 months; return within 30 days
- One year runs from the date of the special resolution or Board resolution. The 7 days run from the last date of completion. The 30-day return goes to the Registrar (and SEBI for listed companies).
- Penalty for buy-back default (Section 68(11))
- Company: ₹1,00,000 to ₹3,00,000; every officer in default: ₹1,00,000 to ₹3,00,000
- Fine only; imprisonment was omitted in 2020.
How to solve Alteration and Reduction of Share Capital; Buy-back questions
Use this method for any question on alteration, reduction or buy-back. Name the section first, then test the conditions one by one.
- 1Identify the event: alteration (no return of capital), reduction (capital cut) or buy-back (company purchases own securities).
- 2For alteration, check that the articles authorise it and the change is one of the five listed in Section 61(1). Note that sub-division must keep the same paid-to-unpaid proportion on each share.
- 3For reduction, state the special resolution, then the Tribunal application, notice to Central Government, Registrar, SEBI (if listed) and creditors, and the three-month window for representations.
- 4For reduction, check the bar: no reduction if the company is in arrears in repaying deposits or interest. Add the auditor's certificate on accounting treatment and the filing of the Tribunal order with the Registrar within 30 days.
- 5For buy-back, list the conditions in order: articles, resolution, 25% limit, 2:1 debt ratio, fully paid-up shares, SEBI regulations or rules, one-year gap.
- 6Do the arithmetic: compute paid-up capital plus free reserves, take 25% (and 10% for the Board route), then compare the debts owed after the buy-back with twice the paid-up capital and free reserves. State your convention: in exam problems, capital and reserves are usually reduced by the buy-back amount unless the question says otherwise.
- 7Add procedure: explanatory statement, declaration of solvency, completion in one year, destruction in 7 days, register, return within 30 days.
- 8Write a conclusion: buy-back permitted or not, and what the company must do or change.
Quickest way: Buy-back in 60 seconds: the 25, 10, 2, 1 check
When to use it: Use for MCQs and for the calculation part of a written buy-back question.
- MCQ trick: 'special resolution' with a number usually points to 25%; 'Board resolution' points to 10%. Debt limit is twice, not equal to, capital plus free reserves.
- Compute the base once: paid-up capital + free reserves. Then 25% of base is the maximum buy-back, and 10% is the Board-only limit.
- Test the debt: total debts owed after the buy-back ≤ 2 × (paid-up capital + free reserves). Section 68(2)(d) only says the debts are measured after the buy-back. In problems, the standard exam convention is to reduce capital and reserves by the buy-back amount, unless the question says otherwise. State this as your working assumption.
- Written format: Provision (section and rule), Facts (your numbers), Conclusion (allowed or not). Show each test on a separate line so each earns a step mark.
- Remember the one-year words: complete within one year; no fresh offer within one year of closure of previous offer.
Common mistakes in Alteration and Reduction of Share Capital; Buy-back
Saying alteration of share capital needs Tribunal approval.
Students mix Section 61 with Section 66.
Fix: Alteration is by general meeting if articles authorise it. Tribunal is needed only for reduction, and for a consolidation and division that changes voting percentages.
Treating cancellation of unissued shares under Section 61 as a reduction of capital.
Both involve diminishing capital.
Fix: Section 61(2) says cancellation of shares not taken or agreed to be taken is not a reduction. No Tribunal order is needed.
Measuring the debts before the buy-back in the debt-equity test.
Students use the balance sheet as given.
Fix: Section 68(2)(d) tests the debts owed after the buy-back against twice the paid-up capital and free reserves. The Act does not spell out a reduction of capital and reserves by the buy-back amount. That adjustment is the usual exam convention, so state it as your assumption and follow any instruction in the question.
Applying 25% to total capital for equity shares without reading the proviso.
Students memorise only the headline limit.
Fix: For equity shares in a financial year, the 25% is measured against total paid-up equity capital in that year. Read what the question asks.
Thinking a Board resolution is enough for any buy-back.
The 10% exception is remembered but its conditions are forgotten.
Fix: Board route needs a buy-back of 10% or less of total paid-up equity capital and free reserves, plus authorisation by articles. Above 10% needs a special resolution.
Forgetting post-buy-back obligations such as 7-day destruction and the 6-month bar on fresh issue.
Students stop at the conditions.
Fix: Add the list: destroy within 7 days, register of buy-back, return within 30 days, no further issue of same kind for six months except bonus issue or discharge of subsisting obligations.
Worked examples
Example 1
A company has paid-up equity share capital of ₹40,00,000 and free reserves of ₹60,00,000. Its total debts are ₹1,50,00,000. The articles authorise buy-back. The company proposes to buy back equity shares worth ₹22,00,000 through a special resolution. Can it do so? (Use the usual exam convention that the buy-back amount is paid out of capital and reserves.)
Show the solution
- Base = paid-up capital + free reserves = ₹40,00,000 + ₹60,00,000 = ₹1,00,00,000.
- 25% limit = 25% of ₹1,00,00,000 = ₹25,00,000. The proposed ₹22,00,000 is within this limit.
- Section 68(2)(d) tests debts owed after the buy-back against twice the paid-up capital and free reserves. By the usual exam convention, we reduce capital and reserves by the buy-back: ₹1,00,00,000 − ₹22,00,000 = ₹78,00,000.
- Maximum debt allowed on this convention = 2 × ₹78,00,000 = ₹1,56,00,000. Debts are ₹1,50,00,000, which is within this.
- Board-only route would not work, since 10% of the base is ₹10,00,000 and ₹22,00,000 is more; special resolution is needed, which the company has proposed.
- Other conditions: shares must be fully paid-up, the buy-back must follow SEBI regulations or the prescribed rules, and no offer of buy-back within one year of the closure of the preceding offer.
Answer: Yes, on the usual exam convention. The buy-back of ₹22,00,000 is within the 25% limit of ₹25,00,000 and the debt of ₹1,50,00,000 is within the ₹1,56,00,000 limit. It is allowed, subject to the special resolution and the other conditions.
Example 2
Using the same facts and the same convention, the company instead proposes a buy-back of ₹30,00,000 by special resolution. Can it proceed? What is the maximum it can buy back?
Show the solution
- Base remains ₹1,00,00,000, so the 25% limit is ₹25,00,000.
- ₹30,00,000 is more than ₹25,00,000, so the size condition under Section 68(2)(c) fails.
- Check the debt test for the maximum of ₹25,00,000. On the exam convention, paid-up capital and free reserves after the buy-back = ₹1,00,00,000 − ₹25,00,000 = ₹75,00,000; twice this = ₹1,50,00,000.
- Debts of ₹1,50,00,000 are not more than ₹1,50,00,000, so the debt test is just satisfied at ₹25,00,000.
- So the highest permitted buy-back is ₹25,00,000, subject to the other conditions.
Answer: No. A buy-back of ₹30,00,000 breaches the 25% limit. The maximum is ₹25,00,000, at which the debt test is exactly met on the usual exam convention.
Exam tips
- In written answers, cite the section and set out the conditions in the Provision-Facts-Conclusion format. Show each numerical test on its own line.
- Learn the distinction chart: Section 61 needs articles and general meeting; Section 66 needs special resolution plus Tribunal; Section 68 needs special resolution (or Board up to 10%) plus the 25% and 2:1 tests.
- For reduction questions, list the Tribunal procedure in order: application, notice to authorities and creditors, three months for representations, auditor's accounting certificate, order, publication, filing with Registrar within 30 days.
- MCQs often test numbers: 25%, 10%, twice, one year, seven days, six months, thirty days, and the fine range of ₹1,00,000 to ₹3,00,000. Revise them together.
- Do not confuse buy-back with reduction: Section 66 expressly does not apply to buy-back under Section 68.

Alteration and Reduction of Share Capital; Buy-back: frequently asked questions
What is the difference between alteration and reduction of share capital?
Alteration under Section 61 changes the structure, such as increase, sub-division or consolidation, and is done in a general meeting if the articles allow. Reduction under Section 66 cuts the capital itself and needs a special resolution and Tribunal confirmation. Cancelling unissued shares is an alteration, not a reduction.
What are the main conditions for a buy-back under Section 68?
The articles must authorise it, and a special resolution is needed unless the Board route applies at 10% or less. The buy-back must be 25% or less, debts owed after the buy-back must not exceed twice paid-up capital and free reserves, and the shares must be fully paid-up. Listed securities follow SEBI regulations.
Can a company buy back shares from the proceeds of an earlier issue of the same kind?
No. The proviso to Section 68(1) bars buy-back of any kind of shares or securities out of the proceeds of an earlier issue of the same kind. Buy-back can be from free reserves, securities premium or the proceeds of any issue other than an earlier issue of the same kind.
How soon must bought-back shares be destroyed?
The company must extinguish and physically destroy them within seven days of the last date of completion of the buy-back. It must also maintain a register and file a return with the Registrar within thirty days of completion.
