Powell Corporation has a taxable temporary difference related to net book value versus UCC of $715,000 at December 31, 2020. This difference will reverse as follows: 2021, $53,000; 2022, $310,000; and 2023, $352,000. Enacted tax rates are 25% for 2021 and 2022, and 30% for 2023. Calculate the amount that Powell should report as a deferred tax asset or liability at December 31, 2020. If the tax rate for 2023 had been 25%, and unexpectedly increased to 30% at the end of 2020, how would the increase in the tax rate for 2023 have affected the deferred tax asset or liability, and the related expense, in 2020?
