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
Tax Loss Carryforwards

---------------|-------------|-------------|------------------|----------
20X1 | _________ | __________ | _________ | _________
20X2 | _________ | __________ | _________ | _________
20X3 | _________ | __________ | _________ | _________
20X4 | _________ | __________ | _________ | _________
Total | _________ | | _________ | _________
DTA on carryforwards: Remaining x Tax Rate = _________
Valuation allowance / non-recognition: (_________)
Net DTA recognized: _________
Utilization constraints:
[ ] Annual usage limit (e.g., Germany: only 60% of income above EUR 1M)
[ ] Minimum tax provisions
[ ] Change of ownership restrictions (e.g., Section 382 US, §8c KStG Germany)
[ ] Separate return limitation year (SRLY) rules

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