SFRS(I) 1-12 prescribes the accounting treatment for income taxes — both the current tax payable on this year's taxable profit and the deferred tax that arises because accounting and tax treat many items differently and on different timing. Its defining feature is the temporary difference (balance sheet) approach: it compares the carrying amounts of assets and liabilities with their tax bases and recognises deferred tax on the differences. It is the Singapore equivalent of IAS 12 under IFRS, and is in substance IAS 12 as applied in Singapore, read alongside Singapore's own corporate tax rules.
Objective and scope
The objective is to prescribe the accounting treatment for income taxes. The principal issue is how to account for the current and future tax consequences of the future recovery (settlement) of the carrying amount of assets and liabilities, and of transactions of the current period. The standard requires an entity to account for the tax consequences of transactions in the same way it accounts for the transactions themselves.
Current tax
Current tax is the amount of income taxes payable (recoverable) in respect of the taxable profit (tax loss) for a period. It is recognised as a liability to the extent unpaid, or as an asset to the extent amounts already paid exceed the amount due. Current tax is measured at the amount expected to be paid to (recovered from) the tax authorities, using tax rates and laws that have been enacted or substantively enacted by the end of the reporting period.
The temporary difference approach
The heart of SFRS(I) 1-12 is the temporary difference (balance sheet) approach. A temporary difference is a difference between the carrying amount of an asset or liability and its tax base (the amount attributed to it for tax purposes). Temporary differences are either:
Taxable temporary differences — differences that will result in taxable amounts in future periods when the carrying amount is recovered or settled. These give rise to deferred tax liabilities.
Deductible temporary differences — differences that will result in amounts deductible in future periods. These give rise to deferred tax assets.
This balance-sheet focus is broader than a pure income-statement (timing difference) approach, because it captures differences that never pass through profit or loss — for example, those arising on revaluations, fair value adjustments, and business combinations.
Deferred tax liabilities and assets
A deferred tax liability is recognised for all taxable temporary differences, subject to specific initial-recognition exceptions (such as goodwill). A deferred tax asset is recognised for all deductible temporary differences, and for the carryforward of unused tax losses and credits, to the extent that it is probable that taxable profit will be available against which they can be utilised. The recoverability of deferred tax assets is reassessed at each reporting date.
Measurement
Deferred tax is measured at the tax rates expected to apply when the asset is realised or the liability settled, based on rates enacted or substantively enacted by the reporting date, and is not discounted. Current and deferred tax are recognised in profit or loss, except where the tax relates to an item recognised in other comprehensive income or directly in equity, in which case the tax is recognised there too.
The Singapore context
SFRS(I) 1-12 is applied against the backdrop of Singapore's corporate income tax regime administered by the Inland Revenue Authority of Singapore (IRAS) — a single-tier corporate tax system with a headline corporate tax rate, various exemptions and incentives, and rules on capital allowances (Singapore's equivalent of tax depreciation) that frequently differ from accounting depreciation. Those differences between accounting carrying amounts and tax bases are exactly what generate temporary differences and hence deferred tax. Tax incentives and partial exemptions can also affect the effective tax rate, which the standard's tax reconciliation disclosure is designed to explain.
A worked example
A Singapore company assesses its temporary differences at the reporting date, applying a corporate tax rate of 17%:
| Item | Carrying amount (S$) | Tax base (S$) | Temporary difference (S$) | Type | Deferred tax @ 17% (S$) |
|---|---|---|---|---|---|
| Equipment (capital allowances exceed depreciation) | 100,000 | 70,000 | 30,000 | Taxable | 5,100 liability |
| Warranty provision (deductible when paid) | 20,000 | 0 | 20,000 | Deductible | 3,400 asset |
The equipment gives a deferred tax liability because capital allowances claimed for tax (reducing the tax base to S$70,000) exceed accounting depreciation, so more will be taxable when the asset is recovered. The warranty provision gives a deferred tax asset because it is deductible for tax only when paid — recognised because the company expects sufficient future taxable profit to use it. The deferred tax amounts are not discounted and are measured at the 17% rate expected to apply when the differences reverse.
How SFRS(I) 1-12 relates to IFRS
SFRS(I) 1-12 is identical to IAS 12 under IFRS — both use the temporary difference (balance sheet) approach, both recognise deferred tax on the difference between carrying amounts and tax bases, both apply the probable-profits test to deferred tax assets, and both recognise the tax on OCI and equity items outside profit or loss. An entity familiar with IAS 12 will find SFRS(I) 1-12 to be the same standard.
Common pitfalls
Recurring issues include applying an income-statement (timing difference) approach rather than the balance-sheet (temporary difference) approach; recognising a deferred tax asset without it being probable that sufficient future taxable profit will be available; discounting deferred tax (not permitted); failing to recognise deferred tax on items taken to OCI or equity in those same components; and not reassessing the recoverability of deferred tax assets at each reporting date.
Why this is cleaner on a unified system
Computing current and deferred tax accurately depends on reliable data about the carrying amounts of assets and liabilities and their tax bases — the source of temporary differences — which is far easier when the underlying records and the ledger sit in one connected system. When the figures that drive temporary differences (capital allowances versus depreciation, provisions, and so on) are maintained in a single source of truth, identifying and tracking those differences and computing the deferred tax is more reliable than reconciling tax computations against accounts held in separate tools.
