IAS 12 — Accounting for uncertainties in income taxes


The IFRS Interpretations Committee observed diversity in practice regarding the recognition and measurement of current tax, deferred tax liabilities and deferred tax assets as defined by paragraph 5 of IAS 12 Income Taxes, when there are uncertainties in the amount of income tax payable (recoverable). As a consequence, the Interpretations Committee decided to develop an interpretation. The interpretation would also include guidance on the determination of units of measurement for uncertainties and on assumptions for tax authorities' examinations and would explain the existing relevant disclosure requirements.
