DEFERRED TAX ASSET VALIDATION BURNDOWN

Introduction

Deferred tax assets (DTAs) represent a critical area of financial reporting that requires careful validation, particularly in Nigeria’s evolving tax landscape. Following the enactment of the Nigeria Tax Act (NTA) 2025, effective 1 January 2026, businesses must reassess their deferred tax balances in line with IAS 12 – Income Taxes .

The removal of the Initial Allowance from capital allowance computation, the shift to a straight-line annual allowance only, and the introduction of the 15% Minimum Effective Tax Rate (METR) for large and multinational groups all have significant implications for deferred tax positions . Businesses that fail to validate their DTAs properly risk P&L surprises, restatement of prior year accounts, and audit complications.

This comprehensive guide provides a burndown of the deferred tax asset validation process, covering the recognition criteria under IAS 12, the NTA 2025 impact on deferred tax, capital loss DTA validation, valuation allowance assessment, and practical steps for compliance.

The Pain Points: Why DTA Validation Matters Now More Than Ever

The NTA 2025 Realignment Shock

The NTA 2025 introduces a fundamental shift in capital allowance computation. The removal of the Initial Allowance means that the temporary difference between accounting carrying amount and tax base of qualifying assets is significantly reduced or eliminated . Under the old regime, accelerated capital allowances (Initial + Annual) created a Deferred Tax Liability (DTL). With the new straight-line annual allowance only, the tax base increases, reducing or eliminating that temporary difference .

Illustration: For a ₦10 million asset with a 5-year useful life and 30% tax rate, the old rule created a DTL of ₦240,000 in Year 1. Under the new rule, the temporary difference is eliminated, and the DTL is reversed to ₦0 . This reversal must be recognised directly in equity (retained earnings) as it arises from a change in tax legislation, not a transaction .

The Capital Loss DTA Complexity

Until recently, capital losses in Nigeria were permanently non-deductible. The legislation now permits deductibility and carry-forward of capital losses for up to 5 years, potentially enabling recognition of deferred tax assets . However, this is not automatic. Businesses must demonstrate that they expect to generate sufficient chargeable gains within the 5-year window to cover the capital losses .

If a business cannot foresee chargeable gains, it cannot recognise DTA. If it later uses up capital losses without having previously recognised DTA—and there was sufficient evidence that it could have recognised the DTA in prior year accounts—those accounts may be wrong and require restatement .

The Valuation Allowance Discipline

Under IAS 12, deferred tax assets should only be recognised to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilised . This requires a disciplined assessment of all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and recent operating results .

Where cumulative losses exist and continued net operating losses are expected, a full valuation allowance is required. The Company’s effective tax rate may be 0% due to the full valuation allowance on net deferred tax assets .

The Revaluation Surplus Trap

When non-depreciable assets such as land are revalued, a temporary difference arises between the carrying amount (revalued) and the tax base (original cost). Under NTA 2025, Capital Gains Tax on the disposal of capital assets has increased from 10% to 30% . This means the deferred tax liability on revaluation surpluses must be recalculated using the higher rate. For land revalued from ₦200 million to ₦250 million, the DTL is 30% × ₦50 million = ₦15 million, recognised directly in OCI .

The Minimum Effective Tax Rate Interaction

The NTA 2025 introduces a 15% Minimum Effective Tax Rate (METR) for large and multinational groups . This significantly impacts deferred tax assets and liabilities. Businesses must review their deferred tax positions now to avoid major P&L surprises . The interaction between METR and DTA recognition requires careful analysis, as the minimum tax may limit the benefit of certain deferred tax assets.

IAS 12 Recognition Criteria for Deferred Tax Assets

Fundamental Principle

A deferred tax asset is recognised for deductible temporary differences, 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 can be utilised .

Key Concepts

Temporary Differences: Differences between the carrying amount of an asset or liability in the statement of financial position and its tax base .

Deductible Temporary Differences: Temporary differences that will result in amounts that are deductible in determining taxable profit (tax loss) of future periods when the carrying amount of the asset or liability is recovered or settled .

Tax Base: The amount attributed to an asset or liability for tax purposes .

Recognition of Deferred Tax Assets

Deferred tax assets are recognised for:

• Deductible temporary differences

• Unused tax losses

• Unused tax credits

To the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilised .

Items with No Deferred Tax

There is no deferred tax to recognise on items that are not taxed or for which no tax relief is given . For non-taxable items, the tax base is set to be the same as the carrying amount, resulting in a nil temporary difference .

The DTA Validation Burndown Process

Step 1: Identify All Temporary Differences

The first step is to identify all temporary differences between the carrying amounts of assets and liabilities in the financial statements and their tax bases .

Common sources of temporary differences include:

• Situations when income or expense is included in accounting profit in one period but in taxable profit in a different period

• Accounting depreciation not equalling tax allowable depreciation (capital allowances)

• Revaluation of assets where tax authorities do not amend the tax base

• Interest receivable taxed on a cash basis

• Development costs capitalised under IAS 38 but tax relief given when paid

Step 2: Classify Temporary Differences

Classify each temporary difference as:

• Taxable temporary differences: Result in taxable amounts in future periods (giving rise to DTL)

• Deductible temporary differences: Result in deductible amounts in future periods (potentially giving rise to DTA)

Step 3: Assess Probable Future Taxable Profit

For each deductible temporary difference, assess whether it is probable that future taxable profit will be available against which the deductible temporary difference can be utilised.

Positive evidence to consider :

• Future reversals of existing taxable temporary differences

• Projected future taxable income

• Tax-planning strategies

• Recent operating results

Negative evidence to consider :

• Cumulative losses

• Continued net operating losses

• History of loss-making operations

Step 4: Apply the Valuation Allowance

Where it is not probable that taxable profit will be available, a valuation allowance must be recognised against the deferred tax asset.

The Company recognises deferred tax assets to the extent that it believes these assets are more likely than not to be realised . Where cumulative losses exist and continued net operating losses are expected, a full valuation allowance is required .

Example: A company with net operating loss carryforwards of $54,991,590 and cumulative losses determined that a full valuation allowance was required, resulting in a net deferred tax asset of $0 and an effective tax rate of 0% .

Step 5: Calculate the DTA/DTL

Deferred tax assets and liabilities must be 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 tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period .

Important: Deferred tax assets and liabilities must not be discounted .

Step 6: Offset Deferred Tax Assets and Liabilities

A company must offset deferred tax assets and deferred tax liabilities if, and only if:

• The entity has a legally enforceable right to set off current tax assets against current tax liabilities; and

• The deferred tax assets and the deferred tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle on a net basis or to realise the assets and settle the liabilities simultaneously .

Key Principle: The existence of a deferred tax liability is strong evidence that a deferred tax asset from the same tax authority will be recoverable .

Step 7: Disclose Components of Tax Expense

The major components of tax expense (income) must be disclosed separately :

• Current tax expense (income)

• Adjustments recognised in the period for current tax of prior periods

• The amount of deferred tax expense (income) relating to the origination and reversal of temporary differences

• The amount of deferred tax expense (income) relating to changes in tax rates or the imposition of new taxes

• The amount of the benefit arising from a previously unrecognised tax loss, tax credit or temporary difference of a prior period

NTA 2025 Impact on Deferred Tax

Removal of Initial Allowance

The NTA 2025 removes the Initial Allowance from capital allowance computation. Under the old regime, the accelerated capital allowance (Initial + Annual) created a temporary difference between the accounting carrying amount and the tax base of qualifying assets, resulting in a DTL .

With the new rule applying only a straight-line annual allowance, the tax base increases, reducing or eliminating the temporary difference .

Illustration :

• Asset cost: ₦10,000,000

• Useful life (accounting): 5 years

• Accounting depreciation: ₦2,000,000/year

• Tax rate: 30%

Transition Treatment: When tax laws change, IAS 12 requires that the deferred tax change be recognised in equity (typically retained earnings) if it does not relate to a transaction recognised in profit or loss. The existing DTL is reversed with an entry: Dr Deferred Tax Liability; Cr Retained Earnings / OCI .

Capital Gains Tax Rate Increase

The NTA 2025 increases Capital Gains Tax on the disposal of capital assets from 10% to 30% . This impacts deferred tax on revaluation surpluses for non-depreciable assets such as land.

Example: Land initially recorded at ₦200 million is revalued to ₦250 million, creating a revaluation surplus of ₦50 million recognised in OCI. The tax base remains at ₦200 million. The temporary difference of ₦50 million gives rise to a DTL at 30% = ₦15 million, recognised directly in OCI .

Minimum Effective Tax Rate (METR)

The NTA 2025 introduces a 15% Minimum Effective Tax Rate for large and multinational groups . This significantly impacts deferred tax assets and liabilities. Businesses must review deferred tax positions to avoid major P&L surprises. The METR may limit the benefit of certain deferred tax assets .

Realignment Checklist for Q1 2026

The NTA 2025 Implementation Roadmap identifies Deferred Tax Realignment as one of five critical steps for Q1 2026 tax planning :

• The total shift in rates and the new 15% METR will significantly impact deferred tax assets and liabilities

• Review these now to avoid major P&L surprises

Capital Loss DTA Validation

The New Capital Loss Deductibility Regime

In Nigeria, capital losses arising from the disposal of capital assets are now deductible from chargeable gains arising from the same category of capital assets. The legislation now permits deductibility and carry-forward of capital losses for up to 5 years .

DTA Recognition for Capital Losses

There is potential to treat capital losses as ‘temporary differences’ and recognise deferred tax assets, as the legislation now permits deductibility and carry-forward for up to 5 years .

However: You should not be in a hurry to recognise DTA on capital losses. You need to demonstrate that you expect to generate sufficient chargeable gains within the next 5 years to cover the capital losses .

The Evidence Challenge

If you cannot foresee chargeable gains, you cannot recognise DTA. If you end up using up the capital losses without previously recognising DTA on them—and there is sufficient evidence that you could have recognised the DTA in your prior year accounts—those accounts may be wrong, which will then require restatement if the impact is material to your auditors .

Practical Challenge: Estimating future chargeable gains on similar class of assets is not as determinable as estimating future taxable profits for income tax purposes .

Frequently Asked Questions

Q: What is a deferred tax asset?
A: A deferred tax asset (DTA) is recognised for deductible temporary differences, 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 can be utilised .

Q: How does NTA 2025 affect deferred tax?
A: The removal of the Initial Allowance from capital allowance computation requires reassessment of deferred tax balances. The tax base increases, reducing or eliminating temporary differences that previously gave rise to DTLs . The CGT rate increase from 10% to 30% also impacts deferred tax on revaluation surpluses .

Q: Can I recognise DTA on capital losses?
A: Yes, potentially. Capital losses are now deductible and can be carried forward for up to 5 years. However, you must demonstrate that you expect to generate sufficient chargeable gains within the 5-year window .

Q: What is a valuation allowance?
A: A valuation allowance is recognised against deferred tax assets where it is not probable that taxable profit will be available to utilise the deductible temporary difference. Where cumulative losses exist and continued net operating losses are expected, a full valuation allowance is required .

Q: How is deferred tax measured?
A: Deferred tax assets and liabilities must be 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 enacted or substantively enacted tax laws. They must not be discounted .

Q: When can deferred tax assets and liabilities be offset?
A: Offset is allowed if the entity has a legally enforceable right to set off current tax assets and liabilities, and the deferred tax assets and liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities intending to settle on a net basis .

Q: How should the NTA 2025 deferred tax change be recognised?
A: When tax laws change, IAS 12 requires the deferred tax change to be recognised in equity (typically retained earnings) if it does not relate to a transaction recognised in profit or loss. The existing DTL is reversed with an entry: Dr Deferred Tax Liability; Cr Retained Earnings / OCI .

The Bottom Line

Deferred tax asset validation is a critical financial reporting discipline that has become even more important with the enactment of the NTA 2025. The removal of Initial Allowance, the CGT rate increase, and the introduction of the 15% METR all require businesses to reassess their deferred tax positions.

Key Takeaways:

Reassess Capital Allowance Temporary Differences: The removal of Initial Allowance significantly reduces or eliminates the temporary difference between accounting carrying amount and tax base of qualifying assets. Existing DTLs may need to be reversed .

Validate Capital Loss DTA Carefully: Capital losses can now support DTA recognition, but only if you can demonstrate probable future chargeable gains within 5 years. Premature recognition risks restatement .

Apply Valuation Allowance Discipline: DTAs should only be recognised to the extent that it is probable that taxable profit will be available. Cumulative losses may require a full valuation allowance .

Recalculate Revaluation Surplus DTL: The CGT rate increase to 30% requires recalculation of deferred tax on revaluation surpluses for non-depreciable assets, recognised in OCI .

Review METR Interaction: The 15% Minimum Effective Tax Rate may limit the benefit of certain deferred tax assets. Review your positions now to avoid P&L surprises .

Your job is to be prepared. Understand the NTA 2025 changes. Validate your deferred tax assets. Apply IAS 12 recognition criteria. Seek professional guidance.

With the right approach and the right partner, you can turn deferred tax validation from a compliance burden into a reliable and accurate financial reporting process.
