Deferred Tax Accounting

name: deferred-taxes description: Deferred tax accounting — temporary differences, DTA recognition. Cover temp vs permanent, DTA/DTL, tax loss carryforwards.

When to Activate

• Identifying and measuring temporary differences between tax and accounting bases
• Recognizing deferred tax assets (DTA) and deferred tax liabilities (DTL)
• Assessing recoverability of deferred tax assets
• Accounting for tax loss carryforwards and tax credit carryforwards
• Distinguishing temporary from permanent differences
• Calculating the effective tax rate and reconciling to statutory rate
• Business combinations: deferred taxes arising from purchase price allocations
• Changes in tax rates: remeasuring deferred tax balances
• Intragroup transactions: deferred tax on unrealized profits
• Presenting and disclosing deferred taxes in financial statements

Core Concepts

Temporary vs Permanent Differences

Temporary differences — differences between the carrying amount of an asset or liability in the financial statements and its tax base that will reverse in future periods:

Type	Example	Effect
Taxable temporary	Accelerated tax depreciation (tax base < book value)	DTL — tax paid later
Deductible temporary	Warranty provisions (tax base > book value)	DTA — tax saved later
Taxable temporary	Revenue recognized for tax before book (e.g., installment)	DTL
Deductible temporary	Impairment losses not yet tax-deductible	DTA

Permanent differences — differences that will never reverse. No deferred tax is recognized:

• Tax-exempt income (e.g., municipal bond interest under US GAAP)
• Non-deductible expenses (e.g., certain fines, entertainment in some jurisdictions)
• Tax credits
• Participation exemption on dividends (many EU jurisdictions)

Key distinction: Temporary differences create deferred taxes; permanent differences affect only the effective tax rate.

Deferred Tax Assets (DTA)

Recognition:

DTA arises from:
  - Deductible temporary differences
  - Tax loss carryforwards
  - Tax credit carryforwards

IAS 12 (IFRS):
  Recognize DTA to the extent that it is PROBABLE (> 50%) that
  future taxable profit will be available against which the
  deductible differences/losses can be utilized.

ASC 740 (US GAAP):
  Recognize DTA in full, then assess need for VALUATION ALLOWANCE.
  Reduce DTA by valuation allowance if it is MORE LIKELY THAN NOT
  (> 50%) that some or all of the DTA will NOT be realized.

Evidence for DTA recoverability:

• Future reversals of existing taxable temporary differences (most reliable)
• Projected future taxable income (requires forecasts — apply judgment)
• Tax planning strategies available and feasible
• Carryback potential (where tax law permits carryback of losses)
• History of taxable profits (pattern of losses weakens the case)

Positive evidence (supports recognition):

• Strong history of profitability
• Existing contracts or backlog generating future income
• Taxable temporary differences reversing in the same period as deductible differences
• Appreciated built-in gains in assets

Negative evidence (weighs against recognition):

• Cumulative losses in recent years (ASC 740: 3-year cumulative loss is significant negative evidence)
• History of tax loss carryforwards expiring unused
• Unsettled circumstances that may create losses
• Short carryforward periods with expiration risk

Deferred Tax Liabilities (DTL)

Recognition: Generally recognize all DTLs. Limited exceptions:

• Initial recognition exception (IFRS only): Do not recognize DTL on initial recognition of goodwill, or on initial recognition of an asset/liability in a transaction that is not a business combination and affects neither accounting nor taxable profit
• Investments in subsidiaries/associates/JVs: Do not recognize DTL if the parent can control the timing of reversal AND reversal is not expected in the foreseeable future
• Undistributed profits: DTL required if distribution is probable (IFRS) or expected (US GAAP) and would trigger additional tax

Measurement

Rate to apply: Enacted (US GAAP) or substantively enacted (IFRS) tax rate expected to apply when the temporary difference reverses.

Rate changes: When tax rates change, remeasure all deferred tax balances at the new rate. Recognize the effect in:

• P&L: If the underlying transaction was recognized in P&L
• OCI: If the underlying transaction was in OCI
• Equity: If the underlying transaction was in equity

Offsetting: DTAs and DTLs are offset only when there is a legally enforceable right to offset current tax assets/liabilities AND the deferred taxes relate to the same taxable entity and same tax authority.

Business Combinations

In a purchase price allocation (IFRS 3 / ASC 805):

• Recognize DTLs on fair value step-ups of acquired assets (book value for tax remains at historical cost, but accounting base is now at fair value — creating a taxable temporary difference)
• Recognize DTAs on acquired liabilities measured at fair value (e.g., unfavorable contracts, warranty obligations at fair value)
• Exception: No deferred tax on goodwill (under IFRS initial recognition exception)
• Deferred tax impacts can significantly increase or decrease goodwill

Methodology

1. Identify all assets and liabilities with different carrying amounts for book and tax purposes
2. Classify each difference as temporary (reversible) or permanent
3. Measure deferred taxes at the expected reversal rate
4. Assess DTA recoverability (IFRS: probability test; US GAAP: valuation allowance)
5. Present current and deferred tax separately; offset only where permitted
6. Reconcile effective tax rate to statutory rate with clear explanation of each item
7. Disclose expiry dates of losses, unrecognized DTAs, and significant judgments
