Business Losses and Unutilised Capital Allowances in Singapore

When a Singapore company's deductible expenses and capital allowances exceed its income for a Year of Assessment (YA), the excess becomes an unutilised trade loss or unutilised capital allowance. Used correctly these reduce tax in other years or elsewhere in the group, but they are subject to strict qualifying conditions.

Carrying Forward Unutilised Losses and Capital Allowances

Unutilised trade losses and capital allowances may be carried forward indefinitely and set off against future income, provided the qualifying conditions are met.

• Shareholding test: the company's ultimate shareholders and their shareholdings must be substantially the same – broadly at least 50% continuity – on the relevant comparison dates. This applies to both losses and capital allowances.
• Same trade test (capital allowances only): in addition, the company must continue to carry on the same trade or business for which the allowances were granted.

Where the shareholding test fails because of a genuine commercial change of ownership rather than tax avoidance, the company may apply to IRAS for a waiver of the test.

Carry-Back Relief

Instead of carrying attributes forward, a company may elect to carry back unutilised trade losses and capital allowances from the current YA to the immediately preceding YA, capped at S$100,000. The same shareholding test – and, for capital allowances, the same trade test – applies.

An enhanced carry-back of up to three preceding YAs was available on a temporary basis for YA 2020 and YA 2021 as a COVID-19 support measure. That enhancement has lapsed; the standard one-year, S$100,000 cap applies.

Group Relief

Under the group relief system a company may transfer current-year unutilised trade losses, capital allowances and approved donations to another Singapore-incorporated company in the same group. Both must be at least 75% owned, directly or indirectly, by a common Singapore-incorporated parent, and must share the same financial year end. Group relief applies only to current-year items – brought-forward amounts cannot be transferred.

Order of Set-Off

Where several deductions are available they are applied in a prescribed order under Section 37 of the Income Tax Act: current-year capital allowances, then current-year trade losses, then donations, followed by amounts brought forward from earlier years. The ordering matters because unutilised donations expire after five YAs, whereas losses and capital allowances do not.

Practical Points

• Track unutilised amounts by YA and by type – losses, capital allowances and donations carry different rules and expiry.
• Test the shareholding position before any share transfer, restructuring or investor round, since a change can forfeit accumulated attributes.
• Accounting losses and tax losses are not the same figure; the tax computation governs.
• Model whether carry-back (immediate but capped) or carry-forward (unlimited but deferred) gives the better outcome.
