Powell Corporation has a taxable temporary difference related to net book value versus UCC of $715,000 at December 31, 2017. This difference will reverse as follows: 2018, $53,000; 2019, $310,000; and 2020, $352,000. Enacted tax rates are 25% for 2018 and 2019, and 30% for 2020. Calculate the amount that Powell should report as a deferred tax asset or liability at December 31, 2017. If the tax rate for 2020 had been 25%, and unexpectedly increased to 30% at the end of 2017, how would the increase in the tax rate for 2020 have affected the deferred tax asset or liability, and the related expense, in 2017?
