Accounting for Income Taxes: Deferred Tax Assets and Liabilities

Income tax accounting often results in differences between taxable income (as determined under tax law) and accounting income (as reported under GAAP or IFRS). These differences can be either temporary or permanent and lead to the recognition of deferred tax assets (DTAs) and deferred tax liabilities (DTLs) on the balance sheet. Understanding how to account for these deferred items is fundamental for accurate financial reporting and future cash flow analysis.

Temporary vs. Permanent Differences

Temporary differences arise when the tax basis of assets and liabilities differs from their carrying amounts for financial reporting, but these differences will reverse in future periods.Permanent differences result from items recognized for either accounting or tax purposes, but never both (e.g., fines, non-deductible expenses, or tax-exempt income). Permanent differences do not give rise to deferred tax items.

Common Causes of Temporary Differences

• Depreciation methods: Accelerated for tax, straight-line for accounting

• Warranty expenses: Accrued for accounting, deducted when paid for tax

• Bad debt allowances: Estimated for accounting, deducted when written off for tax

• Unearned revenue: Recognized in advance for tax, when earned for accounting

Each of these timing differences creates either a DTA (future deductible amount) or a DTL (future taxable amount).

Recognition and Measurement (US GAAP and IFRS)

• Deferred Tax Assets: Recognized for deductible temporary differences and carryforwards of unused tax losses or credits, to the extent it is probable (IFRS) or more likely than not (US GAAP) that they will be realized.

• Deferred Tax Liabilities: Recognized for all taxable temporary differences.

• Measurement: Based on the enacted tax rates expected to apply in the periods when the temporary differences reverse. Deferred tax assets must be reduced by a valuation allowance if realization is not probable/likely.

Journal Entry Example: Deferred Tax Liability

A company has tax depreciation exceeding book depreciation by $20,000. With a tax rate of 25%:

• DTL = $20,000 × 25% = $5,000

Entry: Dr. Income Tax Expense ................ $5,000

  Cr. Deferred Tax Liability ..................... $5,000

Journal Entry Example: Deferred Tax Asset

A company accrues warranty expense of $8,000 not yet deductible for tax. With a tax rate of 30%:

• DTA = $8,000 × 30% = $2,400

Entry:

 Dr. Deferred Tax Asset ..................... $2,400

  Cr. Income Tax Expense ........................ $2,400

Valuation Allowance for Deferred Tax Assets

If it is not probable/likely that some or all deferred tax assets will be realized (due to insufficient taxable income in the future), a valuation allowance must be established. This reduces the carrying value of deferred tax assets and increases current period tax expense.

Presentation and Disclosure Requirements

Deferred tax assets and liabilities are usually presented as noncurrent items on the balance sheet. Offsetting is allowed only if the company has a legal right of setoff and the taxes relate to the same jurisdiction. Detailed disclosures are required, including:

• Major components of deferred tax assets and liabilities

• Unrecognized deferred tax assets (valuation allowance)

• Nature of significant temporary differences

• Effective tax rate reconciliation

Relevant Standards

• US GAAP: ASC 740 – Income Taxes

• IFRS: IAS 12 – Income Taxes

Both standards require transparent and comprehensive reporting of current and deferred tax items.
