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 Ind AS 12 in India, 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 (liabilities) recognised in the statement of financial position, and of transactions and other events of the current period recognised in an entity's financial statements. The standard requires an entity to account for the tax consequences of transactions and other events in the same way that it accounts for the transactions and events themselves.
Current tax
Current tax is the amount of income taxes payable (recoverable) in respect of the taxable profit (tax loss) for a period. Current tax for the current and prior periods is recognised as a liability to the extent that it has not yet been paid, or as an asset to the extent that the amounts already paid exceed the amount due. The benefit relating to a tax loss that can be carried back to recover current tax of a previous period is recognised as an asset. Current tax is measured at the amount expected to be paid to (recovered from) the taxation authorities, using the tax rates and tax 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 in the statement of financial position and its tax base (the amount attributed to that asset or liability for tax purposes). Temporary differences are either:
Taxable temporary differences — differences that will result in taxable amounts in determining taxable profit (tax loss) of future periods when the carrying amount of the asset or liability is recovered or settled. These give rise to deferred tax liabilities.
Deductible temporary differences — differences that will result in amounts that are deductible in determining taxable profit (tax loss) of 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, except to the extent that it arises from the initial recognition of goodwill, or from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither accounting profit nor taxable profit (with specific rules for transactions giving rise to equal and offsetting temporary differences).
A deferred tax asset is recognised for all deductible temporary differences, and for the carryforward of unused tax losses and unused tax credits, to the extent that it is probable that taxable profit will be available against which the deductible temporary difference (or the unused tax losses or credits) can be utilised — subject to similar initial recognition exceptions. The recoverability of deferred tax assets is reassessed at the end of each reporting period.
Measurement and recognition
Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realised or the liability is settled, based on the tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. Deferred tax assets and liabilities are not discounted.
Current and deferred tax are recognised as income or an expense and included in profit or loss for the period, except to the extent that the tax arises from a transaction or event that is recognised outside profit or loss — either in other comprehensive income or directly in equity — in which case the related tax is also recognised in other comprehensive income or in equity (this is sometimes called backwards tracing). This is consistent with the principle that the tax follows the item to which it relates.
The Singapore context
In Singapore, 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 brief illustration
A Singapore company owns equipment with a carrying amount of S$100,000, but for tax purposes capital allowances have reduced its tax base to S$70,000 — a taxable temporary difference of S$30,000 (more has been claimed for tax than depreciated for accounting, so more will be taxable in future). At a corporate tax rate of, say, 17%, the company recognises a deferred tax liability of S$5,100 (17% of S$30,000). Separately, the company has a provision of S$20,000 that is deductible for tax only when paid — a deductible temporary difference giving a deferred tax asset of S$3,400, recognised because it is probable the company will have sufficient future taxable profit to use it. The deferred tax amounts are not discounted, and are measured at the rate expected to apply when the differences reverse.
How SFRS(I) 1-12 relates to IFRS and Ind AS
SFRS(I) 1-12 is identical to IAS 12 under IFRS, and therefore very closely aligned with Ind AS 12 in India — 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. This is a point worth emphasising for anyone coming from India's older AS framework: AS 22 uses the narrower timing difference (income statement) approach, whereas both Ind AS 12 and SFRS(I) 1-12 use the broader temporary difference approach. So SFRS(I) 1-12 and Ind AS 12 are aligned with each other (both being converged IAS 12), and both differ from AS 22.
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 (which is 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.
