Current tax should be measured at the amount expected to be paid to (recovered from) the taxation authorities, using the applicable tax rates and tax laws. Deferred tax assets and liabilities are usually measured using the tax rates and tax laws that have been enacted. However, certain announcements of tax rates and tax laws by the government may have the substantive effect of actual enactment. In these circumstances, deferred tax assets and liabilities are measured using such announced tax rate and tax laws. Deferred tax assets and liabilities should not be discounted to their present value.
