Group Relief and Loss Carry-Back Relief in Singapore: How Company Groups Can Use Them Together

When one company in a group makes a loss and another is profitable, most business owners assume the loss simply sits on the books until the loss-making entity turns a profit of its own. That is not how Singapore’s corporate tax system works, and treating it that way can mean paying more tax than the law requires.

Singapore’s Income Tax Act 1947 gives company groups two distinct tools for putting current year losses to immediate use: Group Relief under section 37C, which lets one group company transfer its unutilised losses to a related company, and Loss Carry-Back Relief under section 37E, which lets a company apply its own current year losses against its own income from the year before. Used separately, each is useful. Used together, they can meaningfully reduce a group’s overall tax bill for the year, yet few SME groups in Singapore use both in a coordinated way.

This guide sets out what each relief actually requires, how they can be combined, and where groups most often go wrong when claiming them.

What Is Group Relief Under Section 37C?

Group Relief allows a Singapore-incorporated company (the “transferor”) to transfer its current year unutilised capital allowances, trade losses and approved donations to another Singapore-incorporated company (the “claimant”) within the same group, so the claimant can deduct these items against its own assessable income for the same year of assessment.

Qualifying Conditions

To qualify as members of the same group for Group Relief purposes, both companies must:

• Be incorporated in Singapore.
• Have the same financial year end (or have applied to align their accounting year ends).
• Meet the 75% shareholding test, either because one company holds at least 75% of the ordinary share capital of the other, or because both are held at least 75% by a common Singapore-incorporated parent company.
• Maintain that 75% shareholding continuously throughout the relevant period, tested both on ordinary share capital held and on the beneficial entitlement to profits and assets available for distribution.

Only current year items qualify. Capital allowances, trade losses or donations brought forward from an earlier year of assessment cannot be transferred under Group Relief; they can only be used by the company that generated them, carried forward against its own future income.

What Can Be Transferred, and How Much

A transferor can transfer up to 100% of its current year unutilised capital allowances, trade losses and approved donations, subject to the claimant company having sufficient assessable income to absorb them. There is no fixed dollar cap on Group Relief itself, unlike Loss Carry-Back Relief. The transferor and claimant must each make the appropriate election when filing, on the prescribed group relief forms submitted with the Corporate Income Tax Return. The Ministry of Finance’s overview of Singapore’s Corporate Income Tax system is a useful starting point for how Group Relief fits within the wider set of business support measures.

What Is Loss Carry-Back Relief Under Section 37E?

Loss Carry-Back Relief lets a company apply its own current year unutilised capital allowances and trade losses (together referred to by IRAS as “Qualifying Deductions”) against its own assessable income from the immediately preceding year of assessment, generating a refund of tax already paid for that earlier year.

The One Year Window and the $100,000 Cap

Two limits define this relief. First, only the year of assessment immediately preceding the loss year qualifies; there is no reaching back two or three years. Second, the amount that can be carried back is capped at $100,000 per year of assessment, regardless of how much larger the actual loss might be. Amounts in excess of $100,000 that are not transferred under Group Relief remain available to carry forward against future income.

The Same Business Test

To carry back unabsorbed capital allowances specifically, the company must satisfy the “same business” test: it must still be carrying on substantially the same trade, business or profession in the year it wants to carry the allowances back to as it was when the allowances were originally granted. Trade losses carried back are not subject to this test in the same way, but the underlying trade must genuinely still exist.

Using Group Relief and Loss Carry-Back Together

The two reliefs draw on the same underlying pool of current year unutilised capital allowances and trade losses, but they apply that pool in different directions: Group Relief pushes the loss sideways to a related company’s current year income, while Loss Carry-Back Relief pulls the loss backwards against the same company’s own prior year income. A group does not have to choose one or the other. A loss-making company can allocate part of its current year Qualifying Deductions to Group Relief (transferring them to a profitable related company) and use the remainder for its own Loss Carry-Back claim, as long as the total allocated does not exceed the actual amount of unutilised capital allowances and trade losses available, and the carry-back portion does not exceed $100,000.

The practical planning question is one of sequencing and value: does it make more sense to shelter a related company’s current year profit (Group Relief), recover tax already paid by the loss-making company itself in the prior year (Loss Carry-Back), or split the loss between the two? The answer usually depends on which group company has cash flow pressure now, and which one has the higher marginal benefit from the deduction.

Worked Example

Consider a small group of three Singapore-incorporated companies, all sharing the same 31 December financial year end and connected through a common holding company that owns at least 75% of each.

Beta has a current year trade loss of $220,000 and no income of its own in YA 2026 to absorb it. Rather than simply carrying the entire loss forward, Beta’s directors could split it: transfer $130,000 to Alpha under Group Relief (reducing Alpha’s YA 2026 chargeable income from $180,000 to $50,000, since Alpha has sufficient income to absorb the full amount), and carry back $90,000 against Beta’s own YA 2025 chargeable income of $90,000, which fully absorbs the carry-back claim without exceeding the $100,000 cap. This leaves no unutilised balance stranded and no wasted carry-back capacity, but only because the split was sized deliberately against both years’ actual figures. This is exactly the kind of interaction that is easy to miscalculate without modelling both years side by side before the election is filed, since once made, the election cannot simply be revised after the filing deadline has passed.

Filing Requirements: Form C, Not Form C-S

A company that wishes to claim Group Relief or Loss Carry-Back Relief cannot use Form C-S or Form C-S (Lite). Both reliefs must be claimed through the full Corporate Income Tax Return, Form C, together with the accompanying tax computation and the relevant group relief transfer forms. If your group has been filing Form C-S because it is simpler, introducing a Group Relief or Loss Carry-Back claim for the first time means switching that entity to Form C for the year in question. For a refresher on which form applies to your company and what is required for each, see our guide to Form C, C-S and C-S Lite filing, documents required and templates.

Because both reliefs depend on the year of assessment’s chargeable income figures, get your Estimated Chargeable Income filing right first. Our guide on ECI filing, documents required and templates covers what IRAS expects at that earlier stage.

Common Pitfalls to Avoid

• Assuming brought-forward losses qualify. Only current year unutilised capital allowances, trade losses and donations can be transferred under Group Relief or carried back. Losses already carried forward from a prior year must stay with the company that generated them.
• Missing the shareholding continuity test. A group restructuring partway through the year, a new share issuance that dilutes the parent’s stake below 75%, or a change in beneficial entitlement to profits can break Group Relief eligibility even if the headline shareholding percentage looks unchanged on paper.
• Overlooking the partial exemption interaction. Chargeable income calculations for the claimant company still need to account for the corporate tax exemption schemes before and after the transferred deduction is applied. See our guide on corporate tax exemptions and the partial exemption scheme for how these interact.
• Ignoring related party pricing exposure. Groups that shift losses around through intercompany transactions, rather than through the formal Group Relief mechanism, risk drawing transfer pricing scrutiny. If your group has intercompany service or financing arrangements alongside a Group Relief claim, it is worth reviewing our guide to transfer pricing documentation requirements to keep the two areas clearly separated.
• Forgetting that newly incorporated companies may already be tax exempt. A young company within the group might be sitting on a start-up exemption that changes the value of shifting income towards it. Our guide to the Start-up Tax Exemption scheme explains how that exemption interacts with a company’s early chargeable income.
• Filing the election late, or not at all. Both reliefs must be elected within the filing deadline for the relevant year of assessment (typically 30 November for e-filing). If a claim was missed in an earlier year and the company now realises it should have made one, do not simply amend the current year’s return to compensate; IRAS has a formal channel for correcting past filings, covered in our guide to the IRAS Voluntary Disclosure Programme.

Practical Planning Tips for Company Groups

Model both years before you file, not after. Draft the allocation across both reliefs as a single exercise covering every company in the group, rather than letting each entity’s finance team file in isolation.

Keep a clean audit trail of the shareholding structure. Since the 75% test must be met continuously, not just on the last day of the basis period, retain board resolutions, share registers and any allotment or transfer records showing the shareholding chain was intact throughout. This matters most for groups that have recently taken on new investors or restructured.

Coordinate with grant timing where relevant. Groups simultaneously applying for enterprise grants should note that funding decisions can be affected by a company’s reported financial position, so it is worth sequencing tax elections and grant applications with full visibility of both. If your group is exploring the newly consolidated EDGE grant, our practical walkthrough on applying for the EDGE grant step by step may be a useful companion to this article.

Tax relief planning is only one piece of a company’s broader financial picture, and it is worth pairing tax efficiency with sound financial planning and investment decisions at the group level. For readers who want to keep an eye on the broader business environment in Singapore, Singapore financial news is a useful ongoing reference point.

Conclusion

Group Relief and Loss Carry-Back Relief exist because Singapore’s tax system recognises that related companies, and even a single company across two years, should not be taxed as if each year and entity existed in isolation. Used on their own, either relief can meaningfully reduce a group’s tax bill for the year a loss is incurred. Used together, with the allocation modelled across both years before the election is filed, they can extract materially more value from a loss than most SME groups realise is available. The conditions are specific and the forms are unforgiving of late filing, but for a genuinely related group of Singapore companies, this is one of the more underused pieces of the Income Tax Act.
