year. Recognising an obligation at the end of an interim financial reporting period for such costs that have not yet been incurred generally is not consistent with the definition of a liability.

Measuring interim income tax expense
B12 Interim period income tax expense is accrued using the tax rate that would be applicable to expected total annual earnings, that is, the estimated average annual effective income tax rate applied to the pre-tax income of the interim period.
B13 This is consistent with the basic concept set out in paragraph 28 that the same accounting recognition and measurement principles shall be applied in an interim financial report as are applied in annual financial statements. Income taxes are assessed on an annual basis. Interim period income tax expense is calculated by applying to an interim period's pre-tax income the tax rate that would be applicable to expected total annual earnings, that is, the estimated average annual effective income tax rate. That estimated average annual rate would reflect a blend of the progressive tax rate structure expected to be applicable to the full year's earnings including enacted or substantively enacted changes in the income tax rates scheduled to take effect later in the financial year. AASB 112 Income Taxes provides guidance on substantively enacted changes in tax rates. The estimated average annual income tax rate would be re-estimated on a year-to-date basis, consistent with paragraph 28 of the Standard. Paragraph 16A requires disclosure of a significant change in estimate.
B14 To the extent practicable, a separate estimated average annual effective income tax rate is determined for each taxing jurisdiction and applied individually to the interim period pre-tax income of each jurisdiction. Similarly, if different income tax rates apply to different categories of income (such as capital gains or income earned in particular industries), to the extent practicable a separate rate is applied to each individual category of interim period pre-tax income. While that degree of precision is desirable, it may not be achievable in all cases, and a weighted average of rates across jurisdictions or across categories of income is used if it is a reasonable approximation of the effect of using more specific rates.
B15 To illustrate the application of the foregoing principle, an entity reporting quarterly expects to earn 10,000 pre-tax each quarter and operates in a jurisdiction with a tax rate of 20 per cent on the first 20,000 of annual earnings and 30 per cent on all additional earnings. Actual earnings match expectations. The following table shows the amount of income tax expense that is reported in each quarter:
