Carry Forward of Losses and Depreciation in Amalgamation

Updated 11 October 2026 · Fact-checked

Under section 116 of the Income-tax Act, 2025, the accumulated loss and unabsorbed depreciation of an amalgamating company become those of the amalgamated company, if it is an industrial undertaking, ship or hotel company, or another listed case. Conditions on business history, assets and continuity must be met, and losses carry forward for at most eight tax years.

Understand Tax Treatment of Amalgamating and Amalgamated Companies

When two companies merge, the amalgamating company disappears. Its unused business losses and unabsorbed depreciation would normally vanish with it. Section 116 is a special relief that lets the amalgamated company pick them up and set them off against its own profits.

The relief is not for every amalgamation. Section 116(1) lists the eligible cases: a company owning an industrial undertaking, a ship or a hotel amalgamating with another company; a banking company with a specified bank; one or more public sector companies with other public sector companies; and an erstwhile public sector company in a strategic disinvestment case. For the strategic disinvestment case, the amalgamation must be carried out within five years from the end of the tax year in which the restriction on amalgamation in the share purchase agreement ends. If the case is not listed, you do not get the relief.

If the case qualifies, the accumulated loss and unabsorbed depreciation are deemed to be the loss or depreciation allowance of the amalgamated company for the tax year in which the amalgamation took effect. The normal carry forward and set off rules then apply.

Accumulated loss means only the business loss (excluding speculation loss) that the amalgamating company could itself have carried forward and set off under section 112 had there been no amalgamation. Capital losses and speculation losses are outside it. Unabsorbed depreciation is the depreciation allowance that remained to be allowed to the amalgamating company.

There are two guards. Section 116(4) sets conditions on both companies; failing them denies the relief. Section 116(12) caps the carry forward of the accumulated loss: for amalgamations effected on or after 1 April 2025, the loss can be carried forward for not more than eight tax years after the tax year in which it was first computed for the original predecessor entity. Section 116(12) speaks only of the loss forming part of the accumulated loss, so the cap covers only the accumulated loss. Unabsorbed depreciation is not covered by that cap.

Section 116(5) applies if any of the conditions in section 116(4) is not complied with, whether it is a condition on the amalgamating company or on the amalgamated company. The set off of loss or depreciation already made becomes income of the amalgamated company, chargeable to tax for the year in which the non-compliance occurs.

Key rules to remember

Eligible cases (section 116(1))
Industrial undertaking / ship / hotel company amalgamating with another company; banking company with a specified bank; public sector companies with public sector companies; erstwhile public sector company in strategic disinvestment case
Listed cases only. Relief is deemed loss or depreciation of the amalgamated company for the tax year of amalgamation. For the strategic disinvestment case, the amalgamation must be within five years from the end of the tax year in which the restriction in the share purchase agreement ends.
Conditions on the amalgamating company (section 116(4)(a))
Business in which loss/depreciation arose carried on for ≥ 3 years; ≥ 3/4 of book value of fixed assets held 2 years before amalgamation held continuously up to the date of amalgamation
Both conditions must be met.
Conditions on the amalgamated company (section 116(4)(b))
Hold ≥ 3/4 of book value of acquired fixed assets for ≥ 5 years from amalgamation; continue the business for ≥ 5 years; fulfil other prescribed conditions
All must be met. Under section 116(5), non-compliance with any condition in section 116(4), on either company, makes the loss or depreciation already set off income of the amalgamated company in the year of non-compliance.
Time limit on carry forward (section 116(12))
Accumulated loss carried forward ≤ 8 tax years after the tax year the loss was first computed for the original predecessor entity
For amalgamations on or after 1 April 2025. Section 116(12) caps only the loss forming part of the accumulated loss; unabsorbed depreciation is not covered by that cap. The eight years run from the tax year the loss was first computed for the original predecessor entity, so years elapsed before the amalgamation count.
Meaning of accumulated loss
Business loss (excluding speculation loss) that would have been eligible for carry forward under section 112 to the amalgamating company
Capital loss and speculation loss are not included.
Industrial undertaking (section 116(13)(b))
Manufacture or processing of goods; computer software; power generation or distribution; telecom services; mining; construction of ships, aircraft or rail systems
Trading or pure service business generally does not fit unless listed.
Strategic disinvestment (section 116(3)(c))
Sale of shareholding that reduces government or public sector holding to below 51% (it must have exceeded 51% before) and transfers control to the buyer
Loss claim is limited to the loss and depreciation of the public sector company on the date it ceases to be one (section 116(2)).

How to solve Tax Treatment of Amalgamating and Amalgamated Companies questions

Use this order for any question on loss and depreciation in an amalgamation.

  1. 1Check whether the amalgamation is one of the cases in section 116(1). Identify whether the amalgamating company owns an industrial undertaking, ship or hotel.
  2. 2Check the conditions on the amalgamating company: business for three or more years, and three-fourths of fixed assets (book value) held continuously from two years before the amalgamation.
  3. 3Check the conditions on the amalgamated company: three-fourths of assets held and business continued for five years, plus prescribed conditions.
  4. 4Separate the loss. Keep only business loss (not speculation) and unabsorbed depreciation. Drop capital loss and speculation loss.
  5. 5Apply the eight-year limit of section 116(12) to the accumulated loss only, counting from the tax year the loss was first computed. Lapse any loss older than that. Unabsorbed depreciation is not covered by the section 116(12) cap.
  6. 6Set off in the amalgamated company's hands under the normal order and record what is carried forward.
  7. 7If a breach of any section 116(4) condition is given, add the set off amount to the amalgamated company's income in the year of non-compliance.

Quickest way: Four-gate check

When to use it: For MCQs and short case questions asking whether losses pass to the amalgamated company.

  1. Gate 1: is it an eligible case under section 116(1)?
  2. Gate 2: did the amalgamating company meet the three-year and three-fourths asset tests?
  3. Gate 3: will the amalgamated company meet the five-year tests?
  4. Gate 4: is the item a business loss or unabsorbed depreciation, and, if it is a loss, is it within eight tax years? (Section 116(12) caps only the accumulated loss; unabsorbed depreciation is not covered by that cap.)
  5. If any gate fails, the answer is that the loss does not pass, or a prior set off is taxed in the year of breach.

Common mistakes in Tax Treatment of Amalgamating and Amalgamated Companies

  • Treating every amalgamation as eligible to carry forward losses.

    Students remember the tax neutrality of amalgamation and assume the loss benefit follows.

    Fix: Section 116(1) lists specific cases. Check the type of company first.

  • Carrying forward capital losses or speculation losses of the amalgamating company.

    The word loss is read broadly.

    Fix: Accumulated loss means business loss excluding speculation loss. Unabsorbed depreciation is separate.

  • Mixing up the three-year and five-year tests.

    Both use three-fourths and numbers of years.

    Fix: Amalgamating company: three years of business and assets held from two years before. Amalgamated company: five years of holding assets and continuing business after amalgamation.

  • Restarting the eight-year clock from the date of amalgamation.

    The deemed loss is for the year of amalgamation, so students count from there.

    Fix: For amalgamations on or after 1 April 2025 the eight years run from the tax year the loss was first computed for the original predecessor entity.

  • Taxing the breach in the amalgamating company's hands.

    The loss originally belonged to the amalgamating company, so students assume the tax follows it.

    Fix: Section 116(5) applies if any condition in section 116(4) is not complied with. The set off amount becomes income of the amalgamated company, in the year of non-compliance. The amalgamating company has ceased to exist and is not taxed.

Worked examples

Example 1

Sharma Textiles Ltd, which manufactures cloth, amalgamated with Bharat Weaves Ltd on 1 October 2026. Sharma had been in the manufacturing business for 6 years. It held all its fixed assets from two years earlier. It had business loss of ₹40,00,000, which is within the eight-year limit of section 116(12), and unabsorbed depreciation of ₹15,00,000. Bharat Weaves is assumed to hold the acquired assets and continue the business for 5 years, and to meet the other prescribed conditions. Bharat Weaves has profit of ₹70,00,000 before these items in the tax year of amalgamation. What can it set off?

Show the solution
  1. Eligibility: Sharma owns an industrial undertaking (manufacture or processing of goods), so section 116(1)(a) applies.
  2. Amalgamating company conditions: 6 years of business (≥ 3) and assets held continuously, so section 116(4)(a) is met.
  3. The amalgamated company is assumed to meet the section 116(4)(b) conditions, as stated. The relief stays available only while it continues to meet them.
  4. The amalgamation is after 1 April 2025, so the eight-year cap of section 116(12) applies to the loss. It is stated to be satisfied. Section 116(12) caps only the accumulated loss, so it does not cover the unabsorbed depreciation.
  5. Deemed loss of ₹40,00,000 and unabsorbed depreciation of ₹15,00,000 become Bharat Weaves' own for the tax year of amalgamation.
  6. Set off under normal rules. Total available = ₹40,00,000 + ₹15,00,000 = ₹55,00,000, against profit of ₹70,00,000 (the usual set off order applies).
  7. Income left = ₹70,00,000 − ₹55,00,000 = ₹15,00,000.

Answer: On the stated facts, Bharat Weaves can set off the whole ₹55,00,000, leaving ₹15,00,000 of business profit. This is subject to its continuing to meet the section 116(4)(b) conditions. If it breaks them, the set off amount becomes its income in the year of non-compliance (section 116(5)).

Example 2

Mehta Hotels Pvt Ltd, which owned a hotel, merged into Rao Resorts Ltd. Mehta had run the hotel business for only 2 years before amalgamation and had a business loss of ₹25,00,000. Can Rao Resorts carry forward this loss?

Show the solution
  1. A company owning a hotel falls in section 116(1)(a), so the case is an eligible one.
  2. Check section 116(4)(a)(i): the amalgamating company must have been engaged in the business for three or more years.
  3. Mehta ran the business for 2 years, which is less than 3, so the condition fails.
  4. Section 116(4) says the loss shall not be set off or carried forward unless all conditions are met.

Answer: No. Rao Resorts cannot carry forward or set off the ₹25,00,000 loss because Mehta Hotels did not run the business for at least three years.

Exam tips

  • Write the section 116(1) eligible case first. Examiners give marks for identifying why the case qualifies.
  • In case studies, check the number of years in each condition carefully. Changing 3 to 2 years is a common trap.
  • List the conditions in two groups: amalgamating company and amalgamated company. This is easier to read and mark.
  • Mention the consequence of breach (section 116(5)) in any answer on conditions. It applies to non-compliance with any condition in section 116(4), and the tax falls on the amalgamated company.
  • State that the eight-year limit applies for amalgamations on or after 1 April 2025, and that section 116(12) caps only the accumulated loss, not unabsorbed depreciation.

Practice questions from Business Restructuring

Tax Treatment of Amalgamating and Amalgamated Companies: frequently asked questions

Is unabsorbed depreciation also carried forward on amalgamation?

Yes, in an eligible case. Section 116(1) makes the accumulated loss and unabsorbed depreciation of the amalgamating company deemed to be those of the amalgamated company for the tax year of amalgamation.

Does the eight-year limit start from the date of amalgamation?

No. For amalgamations effected on or after 1 April 2025, the loss is carried forward for not more than eight tax years after the tax year in which it was first computed for the original predecessor entity.

What happens if the amalgamated company sells the assets within five years?

If it fails to hold at least three-fourths of the book value of the acquired fixed assets for five years, the conditions in section 116(4) are breached. The loss or depreciation already set off is deemed to be income of the amalgamated company in the year of non-compliance.
