Tax expense for the period, comprising current tax and deferred tax, should be included in the determination of the net profit or loss for the period.
Permanent differences do not result in deferred tax assets or deferred tax liabilities. Taxes on income are considered to be an expense incurred by the enterprise in earning income and are accrued in the same period as the revenue and expenses to which they relate. Such matching may result into timing differences. The tax effects of timing differences are included in the tax expense in the statement of profit and loss and as deferred tax assets or as deferred tax liabilities, in the balance sheet.
While recognising the tax effect of timing differences, consideration of prudence cannot be ignored. Therefore, deferred tax assets are recognised and carried forward only to the extent that there is a reasonable certainty of their realisation. This reasonable level of certainty would normally be achieved by examining the past record of the enterprise and by making realistic estimates of profits for the future. Where an enterprise has unabsorbed depreciation or carry forward of losses under tax laws, deferred tax assets should be recognised only to the extent that there is virtual certainty supported by convincing evidence that sufficient future taxable income will be available against which such deferred tax assets can be realised.
