IRAS Advance Ruling 7/2026: Carrying Forward Unabsorbed Losses and Capital Allowances Through a Section 34C Amalgamation

When two Singapore companies amalgamate under the statutory merger procedure in the Companies Act 1967, one of the biggest commercial questions is what happens to the losses and capital allowances the disappearing company built up over the years. Do they simply vanish into the amalgamation, or can the surviving company use them against its future profits? On 4 May 2026, IRAS published Advance Ruling Summary No. 7/2026, which answers that question for a very common fact pattern: a services subsidiary being folded into its parent, with both companies doing broadly the same kind of work. The ruling is a useful, concrete illustration of how IRAS actually applies the “same trade or business” test in section 34C(25) of the Income Tax Act 1947, and it deserves its own dedicated look alongside our general explainer on the section 34C tax framework for qualifying amalgamations.

What Advance Ruling 7/2026 Actually Decided

The published summary concerns two Singapore-incorporated companies, referred to as Company A and Company B. Company A’s principal activities were investment holding and the provision of business support services to its own subsidiaries and related companies. Company B’s sole activity was providing business support services to its related companies, and critically, those services were the same type of business support services that Company A already provided to its group.

Company B was amalgamated into Company A under section 215F of the Companies Act 1967, with Company A surviving as the amalgamated company. Company A elected for section 34C of the Income Tax Act 1947 to apply to the amalgamation, which is what allows an amalgamation to be treated, for tax purposes, as something other than a taxable disposal of Company B’s assets and a cessation of its trade. Post-amalgamation, Company A took over Company B’s existing service contracts, continued serving the same clients, and kept the same headcount by function that Company B had employed before the merger.

IRAS ruled that Company A’s post-amalgamation income would be regarded as arising from the same trade or business that Company B carried on immediately before the amalgamation. On that basis, Company B’s unabsorbed capital allowances and losses (what the ruling calls the “Unabsorbed Tax Loss Items”) could be deducted against Company A’s income under section 34C(25) of the Income Tax Act 1947, subject to the conditions in sections 34C(23) and 34C(24) and the Income Tax (Amalgamation of Companies) Regulations 2011.

Why the “Same Trade” Finding Mattered

Section 34C exists precisely because, without it, an amalgamation would ordinarily trigger a cessation of trade for the amalgamating company and a fresh commencement of trade for the amalgamated company; a result that would strand unabsorbed capital allowances and losses with an entity that no longer exists. Section 34C lets qualifying amalgamations sidestep that outcome, but only where specific statutory conditions are met.

The reasoning IRAS gave in Ruling 7/2026 was direct: Company A could set off Company B’s Unabsorbed Tax Loss Items because Company A’s income after the amalgamation would be regarded as arising from the same trade or business that Company B carried on immediately before it. The facts that supported this finding were not exotic or engineered. They were the ordinary, observable features of a straightforward internal reorganisation:

None of these factors, taken alone, is decisive. What the ruling illustrates is that IRAS looks at the substance of what is actually being carried on after the amalgamation, not merely at the legal mechanics of the merger under section 215F. A group that wants the same outcome should expect IRAS to ask broadly similar questions of its own facts.

The Statutory Conditions Behind Section 34C(25)

Section 34C(25) does not operate in isolation. IRAS’s ruling was explicit that the deduction of Company B’s unabsorbed items remained subject to the applicable conditions in sections 34C(23) and 34C(24) of the Income Tax Act 1947, together with the Income Tax (Amalgamation of Companies) Regulations 2011. Taxpayers relying on this pathway should also work through the IRAS e-Tax Guide, Tax Framework for Corporate Amalgamations (Fifth Edition), in particular paragraphs 6.12 and 6.13 and Annex A, item D1, which set out the detailed conditions for an amalgamated company to utilise an amalgamating company’s unabsorbed capital allowances, losses and donations.

In practical terms, this means three things need to line up before a group can assume it will inherit an amalgamating company’s tax attributes:

• The amalgamation itself must qualify under section 34C, which generally requires the amalgamation to be carried out for genuine commercial reasons and to satisfy the mechanics set out in the Income Tax (Amalgamation of Companies) Regulations 2011.
• The amalgamated company’s post-amalgamation income must be capable of being regarded as arising from the same trade or business the amalgamating company carried on immediately beforehand, which is the factual test Ruling 7/2026 applies.
• The specific conditions in sections 34C(23) and 34C(24) governing the carry-forward of unabsorbed items must be met on their own terms, separately from the same-trade finding.

Because this is a specific ruling on a specific set of facts, it binds only the applicant and the transaction it describes. IRAS is not obliged to reach the same conclusion on a similar but distinct fact pattern, so a group contemplating an amalgamation with less clear-cut continuity, for example where the amalgamated company plans to wind down part of the acquired business or redeploy staff elsewhere, should not assume this ruling covers it.

A Test That Runs Parallel to, But Is Distinct From, Shareholder Continuity

It is worth being precise about which test is which, because Singapore’s tax rules on carrying forward losses and capital allowances actually contain two separate gateways, and directors sometimes conflate them.

The first is the shareholder continuity test under sections 23 and 37 of the Income Tax Act 1947, which we cover in detail in our article on carrying forward unutilised tax losses and the shareholding test. That test asks whether the same shareholders held at least 50 percent of a company’s shares at both the end of the year the loss or allowance arose and the start of the year it is being used, and it applies to a company using its own brought-forward items over time, without any amalgamation involved.

The second is the “same trade or business” test under section 34C(25), which is what Ruling 7/2026 is about. This test only arises in the amalgamation context: it asks whether the amalgamated company’s income after the merger can be regarded as arising from the same trade the amalgamating company carried on before the merger. It has nothing to do with who holds the shares of either company; it is entirely a question of business continuity and substance.

These two tests can both be relevant in the same transaction but they are answering different questions, and satisfying one does not automatically satisfy the other. A group amalgamating two subsidiaries with identical shareholders throughout could still fail the section 34C(25) same-trade test if the amalgamated company changes the nature of the business materially after the merger, and conversely, a genuine change in business activity does not excuse a company from separately meeting the shareholder continuity requirements for its own brought-forward losses under sections 23 and 37.

How This Fits With the General Section 34C Framework

Our broader explainer on the section 34C qualifying amalgamation framework sets out the general conditions an amalgamation must meet to qualify for tax-neutral treatment in the first place, including the election requirements and the mechanics under the Income Tax (Amalgamation of Companies) Regulations 2011. Ruling 7/2026 sits downstream of that general framework: it assumes the amalgamation already qualifies under section 34C, and then addresses the narrower and separate question of whether the amalgamated company can also inherit the amalgamating company’s unabsorbed capital allowances and losses. Groups that have already worked through our guide on group relief and the transfer of losses and capital allowances within a corporate group will recognise the underlying policy concern: Singapore’s tax system generally tries to avoid stranding genuine, unutilised tax attributes purely because of a corporate restructuring, provided the business substance behind those attributes has genuinely carried through.

This ruling also follows a pattern we have seen elsewhere in IRAS’s advance ruling programme this year. Just as Advance Ruling 9/2026 gave a concrete worked example of the Section 10L economic substance test for a Singapore head office, Ruling 7/2026 gives directors and finance teams a real fact pattern to measure their own amalgamation plans against, rather than having to work purely from the abstract wording of the statute.

Practical Steps Before Relying on This Ruling

Directors planning an amalgamation who want to preserve an amalgamating company’s unabsorbed capital allowances and losses should treat Ruling 7/2026 as a checklist of the kind of continuity evidence IRAS will want to see, rather than as a guarantee that applies automatically to their own transaction.

• Document, before the amalgamation date, exactly what type of income-generating activity the amalgamating company carries on, and be ready to show that the amalgamated company’s post-merger activity matches it.
• Where the amalgamated company will take over the amalgamating company’s client contracts or service agreements, keep records showing that handover, since continuity of the actual income stream was a factor IRAS weighed in Ruling 7/2026.
• Avoid material headcount or functional restructuring in the immediate aftermath of the amalgamation if preserving the amalgamating company’s tax attributes is a priority, since a sudden change in how the business is actually run undercuts the same-trade argument.
• Work through the conditions in sections 34C(23) and 34C(24) and the Income Tax (Amalgamation of Companies) Regulations 2011 separately from the same-trade question, since both must be satisfied.
• Where the facts are genuinely comparable to Ruling 7/2026 and the amounts involved are material, consider applying for your own advance ruling from IRAS rather than assuming this published summary extends to your transaction.

How Raffles Corporate Services Can Help

Amalgamations under section 215F of the Companies Act 1967 are a useful tool for consolidating group structures, but the tax consequences, particularly whether unabsorbed capital allowances and losses survive the merger, depend heavily on the specific facts of how the business is actually carried on before and after. RCS advises Singapore groups on structuring amalgamations so that the section 34C election is available in the first place, and on building the factual record needed to support a same-trade argument under section 34C(25) if the group wants to preserve an amalgamating company’s tax attributes. Where the position is not clear-cut, we also assist with preparing an advance ruling application to IRAS to obtain certainty before the amalgamation is completed.

If your group is planning to merge related companies and wants to understand whether unabsorbed losses or capital allowances will carry through, it is worth reviewing the underlying facts against this ruling well before the amalgamation date is fixed.
