8.2 Deferred Tax on Revalued Assets & OCI/Equity Items

8.2 Deferred Tax on Revalued Assets & OCI/Equity Items

Core Principle: Tax follows the transaction. Under IAS 12's "backwards tracing" mandate, the tax consequence of any event, transaction, or valuation change must be recognized in the exact same accounting statement—Profit or Loss, Other Comprehensive Income (OCI), or directly in Equity—where the underlying item itself was recognized.

One of the most heavily tested areas in professional financial reporting is the interaction between asset revaluation models (under IAS 16 Property, Plant and Equipment and IAS 38 Intangible Assets) and deferred taxation. When an entity marks an asset to fair value, its financial accounting carrying amount changes, but statutory tax authorities continue to calculate tax allowances based on historical cost. Managing the resulting temporary differences requires rigorous application of backwards tracing.

The Principle of "Backwards Tracing" (IAS 12.58 & IAS 12.61A)

Under IAS 12.58, current and deferred tax is recognized as an income or an expense in profit or loss, except to the extent that the tax arises from:

1. A transaction or event recognized, in the same or a different period, outside profit or loss (either in OCI or directly in equity); or
2. A business combination.

IAS 12.61A provides the positive operational rule:

Current tax and deferred tax shall be charged or credited directly to other comprehensive income if the tax relates to items that are credited or charged, in the same or a different period, to other comprehensive income. Current tax and deferred tax shall be charged or credited directly to equity if the tax relates to items that are credited or charged, in the same or a different period, directly to equity.

The "Different Period" Dimension

Crucially, backwards tracing extends across reporting periods. If an item was originally recognized in OCI in Year 1 (e.g., an asset revaluation surplus), any subsequent tax adjustments related to that revaluation—such as an enacted change in corporate tax rates in Year 3—must be charged or credited to OCI, not profit or loss. Profit or loss is never contaminated by tax movements relating to items that bypassed profit or loss.

Asset Revaluations under IAS 16 and IAS 38

When an entity elects the revaluation model under IAS 16.31, property, plant, and equipment is carried at fair value at the revaluation date less subsequent accumulated depreciation and impairment. In contrast, statutory tax laws in almost all jurisdictions (including Australia, the UK, and across the Commonwealth) do not adjust the asset's tax base for revaluation surpluses.

Mechanics of an Upward Revaluation

1. Asset Carrying Amount: Increases to fair value.
2. Tax Base: Remains pegged to historical cost less accumulated tax depreciation.
3. Temporary Difference: Increases ($CA > TB$), creating or expanding a Taxable Temporary Difference.
4. Deferred Tax: A Deferred Tax Liability (DTL) must be recognized.
5. Destination: Because the gross revaluation gain is recognized in OCI under IAS 16, the creation of the DTL is recognized in OCI, reducing the net revaluation surplus credited to the Revaluation Reserve in equity:

$$\text{Net Revaluation Surplus (OCI)} = \text{Gross Fair Value Uplift} - \text{Deferred Tax Liability}$$ $$\text{DTL} = \text{Gross Fair Value Uplift} \times \text{Applicable Tax Rate } (t)$$

Comprehensive Worked Example: Revaluation & Annual Reserve Transfer

Scenario Background

On 1 July 2023, Summit Manufacturing Ltd purchased industrial processing equipment for $1,200,000:

• Useful life: 10 years, zero residual value, straight-line depreciation ($120,000/year).
• Tax depreciation: Exactly matches accounting depreciation ($120,000/year deduction).
• Applicable tax rate: 30%.
• Revaluation date: On 30 June 2026 (end of Year 3), the equipment is revalued to its fair value of $1,400,000.
• Remaining useful life: 7 years.

Step 1: Position Immediately Prior to Revaluation (30 June 2026)

After 3 years of depreciation (FY2024, FY2025, FY2026):

$$\begin{aligned} \text{Accumulated Depreciation} &= 3 \times \$120,000 = \$360,000 \\ \text{Carrying Amount} &= \$1,200,000 - \$360,000 = \$840,000 \\ \text{Tax Base} &= \$1,200,000 - \$360,000 = \$840,000 \\ \text{Temporary Difference} &= \$0 \quad (\text{DTL} = \$0) \end{aligned}$$

Step 2: Accounting for the Revaluation at 30 June 2026

• Fair Value: $1,400,000.
• Gross Revaluation Uplift: $1,400,000 - $840,000 = $560,000.
• Tax Base after Revaluation: Remains $840,000 (tax laws ignore accounting revaluations).
• Taxable Temporary Difference: $1,400,000 - $840,000 = $560,000.
• Deferred Tax Liability: $560,000 $\times$ 30% = $168,000.
• Net Revaluation Surplus in OCI: $560,000 - $168,000 = $392,000.

Journal Entries at 30 June 2026:

1. Elimination of accumulated depreciation against gross asset cost (IAS 16.35(b)):

$$\begin{array}{llrr} \text{Dr} & \text{Accumulated Depreciation} & \$360,000 & \\ \text{Cr} & \text{Plant \& Equipment (Gross Cost)} & & \$360,000 \end{array}$$

1. Recognition of fair value uplift, DTL, and net OCI revaluation surplus:

$$\begin{array}{llrr} \text{Dr} & \text{Plant \& Equipment (Asset)} & \$560,000 & \\ \text{Cr} & \text{Deferred Tax Liability (Balance Sheet)} & & \$168,000 \\ \text{Cr} & \text{Other Comprehensive Income (Revaluation Surplus)} & & \$392,000 \end{array}$$

Closing Equity Balance: Revaluation Reserve = $392,000.

Step 3: Accounting for FY2027 (Year 4) Operations

Over the next financial year (ended 30 June 2027):

1. New Accounting Depreciation: $1,400,000 / 7 years = $200,000.

$$\text{Closing Carrying Amount} = \$1,400,000 - \$200,000 = \$1,200,000$$

1. Tax Depreciation Deduction: Tax authority continues historical cost deduction of $120,000/year:

$$\text{Closing Tax Base} = \$840,000 - \$120,000 = \$720,000$$

1. Closing Temporary Difference at 30 June 2027:

$$\text{Taxable Temporary Difference} = \$1,200,000 - \$720,000 = \$480,000$$ $$\text{Closing Required DTL} = \$480,000 \times 30\% = \$144,000$$

1. Reversal of DTL during FY2027:

$$\text{DTL Movement} = \$168,000 \text{ (opening)} - \$144,000 \text{ (closing)} = \$24,000 \text{ (reduction)}$$

Journal Entry for Deferred Tax in FY2027:

$$\begin{array}{llrr} \text{Dr} & \text{Deferred Tax Liability} & \$24,000 & \\ \text{Cr} & \text{Deferred Tax Income (Profit or Loss)} & & \$24,000 \end{array}$$

Notice where the DTL credit goes: As the asset is used and generates taxable operating revenue, the temporary difference unwinds through Profit or Loss! The $24,000 deferred tax income offsets the excess depreciation expense ($80,000 excess depreciation $\times$ 30% = $24,000).

Step 4: The Annual Transfer from Revaluation Reserve to Retained Earnings

Under IAS 16.41, an entity is permitted (though not strictly mandated) to make an annual reserve transfer from the Revaluation Surplus directly to Retained Earnings as the asset is consumed.

Critical Exam Rule: The annual transfer must equal the excess depreciation net of deferred tax.

$$\begin{aligned} \text{Excess Depreciation (Gross)} &= \$200,000 \text{ (actual)} - \$120,000 \text{ (historical)} = \$80,000 \\ \text{Tax Effect of Excess Depreciation} &= \$80,000 \times 30\% = \$24,000 \\ \text{Net-of-Tax Reserve Transfer} &= \$80,000 - \$24,000 = \$56,000 \end{aligned}$$

Alternatively, calculate the transfer directly from the net OCI surplus:

$$\text{Annual Transfer} = \frac{\text{Net Revaluation Reserve}}{\text{Remaining Life}} = \frac{\$392,000}{7} = \$56,000$$

Journal Entry for the Equity Transfer (30 June 2027):

$$\begin{array}{llrr} \text{Dr} & \text{Revaluation Reserve (Equity)} & \$56,000 & \\ \text{Cr} & \text{Retained Earnings (Equity)} & & \$56,000 \end{array}$$

Exam Trap: This transfer is performed entirely within equity (Statement of Changes in Equity). It is never recycled through Profit or Loss or OCI.

Accounting for Revaluation Deficits (Downward Revaluations)

When an asset drops in fair value below its carrying amount, IAS 16 and IAS 12 mandate a strict two-step order of recognition:

1. Step 1 (Exhaust Existing Revaluation Reserve): To the extent that a revaluation surplus already exists in equity for that same asset, the revaluation decrease is recognized in OCI. The associated DTL previously established is reversed through OCI:
   • Dr Revaluation Reserve (Equity) [Net amount]
   • Dr Deferred Tax Liability [Tax effect]
   • Cr Property, Plant and Equipment [Gross decrease]
2. Step 2 (Excess Deficit to Profit or Loss): Any deficit exceeding the existing revaluation surplus for that asset is recognized immediately as an expense in Profit or Loss. If this creates a deductible temporary difference (or reduces an existing taxable difference), the corresponding tax effect is recognized as a deferred tax benefit in Profit or Loss.

Deferred Tax on Items Recognized Directly in Equity

Not all balance sheet items pass through comprehensive income (P/L or OCI). Under IAS 12.61A, items recognized directly in equity must have their related current and deferred tax effects recognized directly in equity.

1. Transaction Costs of Issuing Equity Instruments (IAS 32.35)

Under IAS 32, incremental transaction costs directly attributable to issuing new equity shares (e.g., legal fees, underwriting commissions, prospectus printing) are accounted for as a deduction from equity (debited to Share Capital or an Equity Reserve).

In many tax jurisdictions (such as Australia under Section 40-880 "blackhole expenditure"), share issue costs cannot be deducted immediately, but are deductible straight-line over 5 years (20% per year).

• Accounting Carrying Amount: $0 (subsumed within equity).
• Tax Base: Remaining future tax deductions.
• Temporary Difference: Deductible temporary difference ($CA < TB$).
• Deferred Tax Accounting: A Deferred Tax Asset (DTA) is recognized with the corresponding credit recognized directly in Equity:

$$\begin{array}{llrr} \text{Dr} & \text{Deferred Tax Asset} & \$X & \\ \text{Cr} & \text{Share Capital / Equity Reserve} & & \$X \end{array}$$

2. Compound Financial Instruments (IAS 32 Split Accounting)

When an entity issues convertible notes, IAS 32 mandates split accounting at inception:

• Liability Component: Measured at fair value (present value of debt cash flows discounted at market rate for non-convertible debt).
• Equity Component (Conversion Option): Measured as the residual excess of proceeds over the liability component.

If local tax law treats the convertible note strictly as debt with a tax base equal to nominal face value, a taxable temporary difference arises on the liability component at inception ($TB = \text{Face Value} > CA = \text{Present Value}$). The resulting DTL is debited directly against the Equity Conversion Option in equity, ensuring that the net equity recognized reflects the after-tax value of the conversion privilege.
