Pretax financial income (or loss) and taxable income (loss) were the same for all years involved. Assume a 25% tax rate for 2017 and a 20% tax rate for the remaining years. Prepare the journal entries for the years 2017 to 2021 to record income tax expense and the effects of the net operating loss carryforwards. All income and losses relate to normal operations. (In recording the benefits of a loss carryforward, assume that no valuation account is deemed necessary.) (Credit account titles are automatically indented when amount is entered. Do not indent manually. If no entry is required, select "No Entry" for the account titles and enter 0 for the amounts.)
