IAS 12 Deferred Tax on OCI: Recognizing Tax Effects in Other Comprehensive Income

Many transactions flow through Other Comprehensive Income (OCI) rather than P&L— revaluations, foreign currency translations, gains/losses on financial instruments. IAS 12 requires recognizing the tax effect of these items in OCI (not P&L), a "matching" principle that is frequently misstated. This guide covers the mechanics and audit red flags.

The Matching Principle for Deferred Tax

Rule: Recognize the tax effect of a transaction in the same location (P&L or OCI) as the pre-tax transaction itself. A revaluation gain in OCI should have its tax effect in OCI, not P&L.

Common OCI Items with Deferred Tax Effects

1. Property Revaluation (IAS 16)

Upward revaluation recognized in OCI (or equity). Deferred tax on the revaluation goes to OCI.

2. Foreign Currency Translation (IAS 21)

Translation differences on consolidating foreign subsidiaries go to OCI. Deferred tax effect goes to OCI.

3. Financial Instruments (IFRS 9)

Fair value gains/losses on FVOCI instruments recognized in OCI. Deferred tax effects go to OCI.

4. Defined Benefit Pension (IAS 19)

Remeasurement gains/losses (actuarial gains/losses) go to OCI. Deferred tax effects go to OCI.

Worked Example: Property Revaluation

Scenario

Company revalues its office building:
— Cost: £5m (historical)
— Fair value: £8m (current)
— Revaluation gain: £3m
— Tax base: £5m (still)
— Tax rate: 19%

Journal Entries (Incorrect — Common Error)

Problem: Revaluation gain in OCI, but tax effect in P&L (mismatched locations).

Journal Entries (Correct)

Result: Net OCI effect: £3m −’ £0.57m = £2.43m (after-tax revaluation).

Worked Example: Foreign Subsidiary Consolidation

Scenario

US parent consolidates UK subsidiary:
— UK subsidiary equity: £10m (GBP)
— USD exchange rate movement: 1.30 →’ 1.20 USD/GBP
— Translation loss: £10m × (1/1.20 −’ 1/1.30) ≈ £0.64m
— UK tax rate: 19%
— Is translation difference tax-deductible? NO (foreign translation not tax-deductible)

Journal Entry (Consolidation)

Note: No deferred tax adjustment (translation differences are not tax-deductible in most jurisdictions).

Deferred Tax on OCI: When Not to Apply

Translation Differences

Foreign currency translation differences are not deductible for tax; no deferred tax.

Reclassification Adjustments

When an OCI item reclassifies to P&L (e.g., selling an FVOCI investment), the OCI item doesn't "reverse" from a tax perspective; no deferred tax reversal.

Audit Red Flags: SORIE Deferred Tax

Red Flag 1: Tax Effect in Wrong Location

Finding: Property revalued upward £5m (OCI); deferred tax on revaluation sent to P&L tax expense.

Auditor action: Reclassify deferred tax adjustment to OCI; adjust P&L tax expense and equity.

Red Flag 2: Non-Deductible Revaluation Taxed

Finding: Goodwill impairment of £10m recorded in OCI; deferred tax of £1.9m (@ 19%) recognized. But goodwill is non-deductible; no tax effect exists.

Auditor action: Remove deferred tax on non-deductible items; reverse the OCI tax adjustment.

Red Flag 3: Tax Rate Applied to Non-Tax Item

Finding: Actuarial gain on pension (OCI) of £2m; deferred tax effect of £0.38m applied. But company is loss-making with full valuation allowance on DTA.

Auditor action: If DTA is fully valuation-allowed, no deferred tax effect on OCI items either (tax rate irrelevant). Reverse the deferred tax.

SORIE Presentation

The Statement of Changes in Equity (SOCIE) or Statement of Comprehensive Income (OCI statement) must separately identify:

• OCI items before deferred tax (gross)
• Deferred tax effects
• OCI items after deferred tax (net)

Example SORIE Presentation:
OCI items (before deferred tax):
    Property revaluation £5.0m
    Foreign exchange difference (0.8m)
    Financial instruments FVOCI £1.2m
Deferred tax on above £0.71m
OCI (net of tax): £5.6m
