A Brief Review of IFRS Income Tax Exposure Draft, IAS12, and FAS 109
BY: M Chowdhury
IFRS and US GAAP both use balance sheet approach to recognize differences in taxes due to differences in book value of the assets or liability and their tax base. The IFRS standards are based on IAS 12 (Income Taxes) while the primary source of US GAAP is FAS 109 (Accounting for Income Taxes). Although the IFRS and US GAAP share the same temporary difference approach, the two models differ when it comes to application. Most of the divergences resulted from the treatment of certain exception items. Some other differences resulted from the difference in the recognition and measurement of deferred tax assets and liabilities and also the allocation of tax to equity or other comprehensive income. The divergences create non compatible financial statements.
In March 2009 the IFRS issued exposure draft “Income Tax”. The exposure draft, which proposes significant changes to IAS 12, is part of the convergence project between IFRS and FASB. The exposure draft attempts to reduce the divergence between the US GAAP and IFRS by eliminating all exceptions and establishing a common approach to the recognition and measurement of tax assets and liabilities. The board seeks public comments on the exposure draft by July 2009.
Meanwhile, the FASB suspended its deliberations on the convergence of income tax project. The board may take smaller project in the future to make FAS 109 more compatible to the IFRS.
The following discussion is based on the March 2009 IFRS exposure draft.
Balance sheet approach:
The concept of recognizing deferred taxes due to the temporary difference in carrying value of the assets in the financial statements and their tax base is similar under IAS12 and FAS 109.
Observation: The exposure draft retains the balance sheet approach of recognizing deferred tax.
Valuation allowance:
A valuation allowance is required if the consumption of the deferred tax assets is not probable. However, unlike the IAS 12 the exposure draft proposes a separate line for the valuation allowance.
Observation: The new proposal aligned with FAS 109.
Definitions of tax basis:
The exposure draft changes the definition of the tax basis stated under IAS 12 to the existing practice under US GAAP. Tax basis under FAS 109 generally implies the amount that would be recognized under the existing tax laws of a tax jurisdiction. The IASB proposes that tax basis be defined as the measurement under applicable substantively enacted tax laws of an asset, liability, or other item. The ED also proposes an additional method for determining tax basis which is the amount of tax deductions that would be available if the entity recovered the carrying amount by selling the asset. In another word the tax consequences results from the sales of the assets or settlement of the liability. The purpose of this method is to address the multiple tax implications results from sale or the use of the asset.
The proposal essentially removes the management intentions or expectations about the recovery or settlement of an assets or liability under IAS 12.
Observation: Although the IASB proposals align the definition of tax basis with US GAAP but the difference remains in the definition of tax law. The IFRS requires the measurement of deferred tax using substantively enacted tax law while the US GAAP uses enacted law.
Definitions of temporary difference:
IAS 12 defines temporary differences are the differences between the carrying amount of the assets or liabilities in the financial statements and their tax basis irrespective of whether these temporary differences have any impact on the taxable profit. The exposure draft proposes that temporary differences be defined as the differences between the carrying amount of the assets or liabilities in the financial statements and their tax basis only if the entity expects that there will be an impact on the taxable profit when the carrying amount is settled or realized.
Observation: The board proposal is consistent with the US GAAP.
Tax credit and investment tax credit:
IAS 12 does not address the accounting treatment for tax credit or investment tax credit. The IASB exposure draft defines tax credit as an amount which reduces the future taxes payable and investment tax credit is directly related to a depreciable asset purchase.
Observation: The exposure draft proposes definition for tax credit or investment tax credit, which converges with US GAAP.
Tax rate for deferred tax:
The ED proposes to continue to use substantially enacted tax rate to measure deferred tax assets and liabilities. The proposal is similar to the current requirements of IAS 12. The FAS 109 requires the use of enacted tax rate expected to apply at the end of the reporting period to measure deferred taxes. The board justifies its decision to use substantially enacted tax rate on the premise that in some jurisdictions there is a time lag of few months between the announcements of the new tax rate or law and the actual date of enactment. According to IASB substantive enactment is achieved when any future steps in the enactment process will not change the outcome. In the US this threshold is met when there is no threat from the presidential veto.
Observation: IASB provides additional clarity by defining the reason for the term substantially enacted tax rate. The broad definition of enacted tax rate is intended to address the myriad tax laws in countries around the world.
Classification of deferred tax assets and liabilities:
The current standard (IAS 1) requires that deferred tax be classified as current assets or liabilities regardless of the classification of the underlying assets or liabilities responsible for the deferred tax.
The ED requires that deferred tax assets or liabilities to be classified as current or non current based on the classification of the underlying assets or liabilities.
Observation: The IASB proposal aligns with the classification required by FAS 109
Alternative Minimum Tax:
FAS 109 requires the use of AMT rate when the condition exists for such rate. However, IAS 12 is silent on AMT. The ED proposes to follow the FAS 109 requirements with regards to AMT.
Intercompany transactions:
The ED proposes to retain the current IAS 12 requirements regarding intercompany transactions.
FAS 109 requires that taxes on intercompany profits (on non consolidating tax returns) be deferred until the asset is sold to a third party. Under IAS 12 the tax on the profits will be recognized immediately.
The ED proposes additional disclosures to alleviate any concerns or impression of earnings management. The board proposes reconciliation between the opening and ending balance of the deferred tax assets and liabilities, for each type of temporary differences and each type of unused tax losses and credits.
Observation: The IFRS position is more practical.
Uncertain tax positions:
IAS 12 does not address any uncertainty relating to the tax position taken by an entity in its tax return.
The FIN 48 Accounting for Uncertainty in Income Taxes –an Interpretation of FASB Statement No. 109 provides guidance on the uncertain tax positions. An entity should recognize the tax benefits in full if it is more likely than not that the tax authority will accept the tax positions. FIN 48 requires entity to use a cumulative probability measurement approach in determining the threshold to recognize the tax benefits.
In the exposure draft the board did not agree with the underlying concept of FIN 48 because it was not consistent with the approach taken in the amended IAS 37 which does not allow any probability based threshold to recognize benefits. The board took the position that any uncertainty should be considered in the measurement of the deferred tax assets or liabilities by using probability weighted- average of all outcomes. The probability based threshold is no longer necessary. Additionally, the board proposes that entity should make additional disclosure regarding uncertain tax positions.
Observation: The removal of probability based threshold may require more thorough review of the tax positions companies have taken.
Intraperiod tax allocation:
Intraperiod allocation refers to allocation of tax expense and liability to various sub-classifications such as between continued and discontinued operation, comprehensive income and equity
The board acknowledges the complexity associated with the application of IAS 12 and FAS 109. In some situations backward tracing requirements of IAS 12 is appropriate but in other situations they are difficult and produce arbitrary results. The board, after much deliberation, decided to adopt the allocation approach of FAS 109 which is more fully specified method than IASB 12. But knowing the complexity with FAS 109 the board has kept open the IAS 12 methods for further comments and review.
The current IAS 12 uses a method called backward tracing to allocate the tax benefit or expense. The model requires that tax benefits or expenses out side of continuing operation to be allocated to the same place where the pre tax item was initially recorded.
Observation: In principal the FAS 109 approach is similar to IAS 12 however the FAS 109 model prohibits backwards tracing. Generally intraperiod tax allocation triggered by irregular or extra ordinary items, capital transactions, or prior period adjustments. Income tax expense related to continued operation needs to be disclosed separately but the taxes related to extraordinary items or discontinued operation can be presented net of taxes. Under FAS 109 income taxes are computed twice, once on the overall income from the current operation without taken into account any irregular item and second time the income tax is computed on all income including all irregular items. The difference between the two calculations belongs to the extraordinary item.
