Note: See the attached excel file for the calculation of cumulative temporary book-tax difference for the depreciable asset and the balance to be reported in the deferred tax liability account for December 31 of years 2021, 2022, 2023 and 2024 in bold red color.
In the attached excel file, the following formula are used:
Cumulative Temporary differences at December 31 of the current year = Cumulative Temporary differences at December 31 of the previous year + (Depreciation on the tax return at December 31 of the current year - Depreciation on the income statement at December 31 of the current year)
Balance to be reported in deferred tax liability account at December 31 of the current year = Cumulative Temporary differences at December 31 of the current year * Tax rate
