Liability in Amalgamation, Merger and Company Liquidation under GST
Updated 5 October 2026 · Fact-checked
When companies merge with a retrospective effective date, supplies between them in that gap stay taxable and count in each company's aggregate turnover (Section 87). When a company is wound up, the liquidator must intimate the Commissioner within 30 days, who notifies the amount to set aside within three months (Section 88).
Understand Liability in Amalgamation, Merger and Company Liquidation
Chapter XV of the CGST Act deals with who pays tax when the normal taxable person changes or disappears. This topic covers two such events: a merger of companies and the winding up of a company.
A note on numbering. Many students search for "Section 86" for amalgamation. Section 86 deals with agents and principals. Amalgamation or merger is Section 87, and company in liquidation is Section 88. Write the correct numbers in the exam.
Amalgamation or merger (Section 87). A court or Tribunal order sanctioning a merger often takes effect from an earlier date, called the appointed date. Suppose two of the merging companies traded with each other between the appointed date and the date of the order. Under the merger accounting, these may look like internal dealings. GST does not accept that. Such supplies are still treated as supplies. They are included in the aggregate turnover of the respective companies, and each company is liable to pay tax on them. The order's retrospective date does not wipe out the tax.
Company in liquidation (Section 88). When a company is being wound up, the liquidator must tell the Commissioner about his appointment within 30 days. The Commissioner inquires and, within three months of receiving the intimation, tells the liquidator what amount will be enough to cover the tax, interest and penalty that is payable now or likely to become payable. The liquidator must keep that amount aside before he distributes the assets. If he distributes assets without doing so, he can be held personally liable.
The logic is simple. Tax is a government dues claim. Creditors and shareholders should not be paid out before the department's claim is provided for.
Liability of directors of a private company on winding up is a separate section (Section 89) and is covered in its own topic. Do not mix it into a Section 88 answer unless the question asks.
Key rules to remember
- Section 87: merger with retrospective effect
- Supplies between merging companies (from the appointed date to the date of the order) → included in each company's aggregate turnover → tax payable by each
- Applies where the order takes effect from a date earlier than the order date and two or more of the merging companies have supplies to or from each other. It applies even if the merger is by court, Tribunal or otherwise.
- Section 88: intimation by liquidator
- Liquidator's appointment date + 30 days = last date to intimate the Commissioner
- Count from the date he becomes appointed. Intimation goes to the Commissioner.
- Section 88: Commissioner's notice
- Date of receipt of intimation + 3 months = last date for the Commissioner to notify the amount
- The three months run from receipt of the intimation, not from the date of appointment. The amount is what the Commissioner thinks sufficient for tax, interest and penalty, whether now payable or likely to become payable.
- Section 88: liquidator's duty and exposure
- Set aside the notified amount before distributing assets; if assets are parted with without doing so, the liquidator can be held personally liable
- State this in plain words. Do not invent limits or sub-section numbers.
How to solve Liability in Amalgamation, Merger and Company Liquidation questions
Use this order for any question on merger or liquidation under GST. It keeps your answer in provision-facts-conclusion form.
- 1Identify the event: merger or amalgamation of companies, or winding up of a company. This decides Section 87 or Section 88.
- 2Note the dates. For a merger, find the appointed date and the date of the order. For liquidation, find the date of the liquidator's appointment and the date the Commissioner received intimation.
- 3For a merger, check the two conditions: the order takes effect from a date earlier than the order date, and two or more of the merging companies had supplies to or from each other in that gap.
- 4If both hold, include each supply in the aggregate turnover of the respective company and state that each company is liable to tax on it, whatever the order says.
- 5For liquidation, compute the 30-day intimation limit and the three-month limit for the Commissioner's notice. Check whether the liquidator complied.
- 6Check what the liquidator did with the assets. If he distributed them without setting aside the notified amount, say he can be held personally liable.
- 7Write the conclusion with the amount and the person liable. Mention Section 89 only if directors of a private company are in the facts.
Quickest way: Two-line trigger method
When to use it: Use this for MCQs and for short-note answers when time is tight.
- Merger: look for "effective from an earlier date" plus "supplies between the merging companies". If both are present, the answer is that the supplies are taxable and form part of each company's aggregate turnover.
- Liquidation: write 30 days (liquidator to Commissioner) and 3 months (Commissioner to liquidator). Then ask: did the liquidator set aside the notified amount before paying others? If not, personal liability.
- Check the section number at the end: 87 for merger, 88 for liquidation.
Common mistakes in Liability in Amalgamation, Merger and Company Liquidation
Quoting Section 86 for amalgamation.
Students use the section number from a search or from memory of the chapter order.
Fix: Memorise the sequence: 85 transfer of business, 86 agents and principals, 87 amalgamation or merger, 88 liquidation, 89 directors of private company.
Treating supplies between merging companies as ignorable because they merged.
Students follow accounting logic where intra-group dealings are eliminated.
Fix: Under Section 87 the supplies between the companies in the retrospective gap remain supplies. They are included in each company's aggregate turnover and taxed.
Applying Section 87 when the merger order is effective from its own date.
Students skip the condition about an earlier effective date.
Fix: Check that the order takes effect from a date before the date of the order. Without that retrospective gap there are no gap supplies to talk about.
Counting the Commissioner's three months from the liquidator's appointment.
Students merge the two time limits into one.
Fix: The 30 days run from appointment of the liquidator. The three months run from the date the Commissioner receives the intimation.
Saying the liquidator pays tax out of his own pocket in every case.
Students overstate personal liability.
Fix: The liquidator is exposed to personal liability when he parts with assets without setting aside the notified amount. If he follows the procedure, the amount is met from the company's assets.
Bringing directors' liability into a Section 88 answer by default.
Students link all liquidation questions to directors.
Fix: Directors of a private company are dealt with under Section 89. Mention it only if the facts ask about directors, and keep it as a separate point.
Worked examples
Example 1
X Ltd and Y Ltd are merged under a scheme sanctioned by the Tribunal on 10 September 2025. The order takes effect from 1 April 2025. In August 2025, X Ltd supplied goods worth ₹40,00,000 to Y Ltd, and Y Ltd supplied services worth ₹15,00,000 to X Ltd (values exclude tax). The merged entity's records show these as internal transfers. Advise on the GST position.
Show the solution
- Provision: Section 87 of the CGST Act applies where a merger order takes effect from a date earlier than the order date and two or more of the merging companies have supplies to or from each other.
- Facts: the order is dated 10 September 2025 but takes effect from 1 April 2025, which is earlier. X Ltd and Y Ltd supplied to each other in August 2025, within the gap period.
- Both conditions are met, so the supplies cannot be ignored on the ground of the retrospective merger.
- X Ltd's aggregate turnover includes its supply of ₹40,00,000 to Y Ltd. Y Ltd's aggregate turnover includes its supply of ₹15,00,000 to X Ltd.
- Each company is liable to pay GST on its own supplies, and the order's wording does not change this.
Answer: The supplies are taxable. ₹40,00,000 is included in X Ltd's aggregate turnover and ₹15,00,000 in Y Ltd's, and each company is liable to pay tax on its supply under Section 87. Showing them as internal transfers is not correct.
Example 2
A liquidator is appointed for Z Ltd on 5 March 2026. He gives intimation to the Commissioner, which is received on 10 April 2026. By a notice, the Commissioner informs him that ₹18,00,000 is needed to cover tax, interest and penalty. The liquidator distributes ₹50,00,000 of the company's assets to creditors without setting aside this amount, and the tax remains unpaid. Examine compliance and liability under Section 88.
Show the solution
- Provision: the liquidator must intimate his appointment to the Commissioner within 30 days. The Commissioner must notify the amount to be provided within three months of receiving the intimation.
- Intimation deadline: 30 days from 5 March 2026 is 4 April 2026. The intimation was received on 10 April 2026, so it appears to be after the 30-day limit. The facts say it was received on 10 April, so the date of giving it should be checked. If it was given after 4 April, the liquidator did not comply with the time limit.
- Commissioner's deadline: three months from receipt on 10 April 2026 ends on 10 July 2026. A notice issued within this period is valid.
- Liquidator's duty: after the notice, he had to provide for the ₹18,00,000 before distributing the assets.
- Facts: he distributed ₹50,00,000 to creditors without setting the amount aside, and the tax is unpaid. This is a breach of his duty under Section 88.
Answer: The liquidator is exposed to personal liability for the unrecovered ₹18,00,000 of tax, interest and penalty because he parted with assets without setting aside the notified amount. Late intimation (if given after 4 April 2026) is a separate non-compliance.
Exam tips
- Write the section number in the first line: Section 87 for merger, Section 88 for liquidation. Examiners often reward correct numbering.
- In case scenarios, underline the dates. Two dates in a merger question (appointed date and order date) signal Section 87. Two dates in a liquidation question signal the 30-day and three-month clocks.
- Answer in provision-facts-conclusion form. State the rule, apply it to the dates and amounts, and give a clear conclusion.
- For MCQs, eliminate options that say supplies between merging companies are exempt or ignored, or that the liquidator is always personally liable.
- Keep Section 85 (transfer of business) and Section 89 (directors) as separate points. Mention them only if the facts need them.
