a. To calculate B12 Corporation's 2022 taxable income after the Net Operating Loss (NOL) deduction, subtract the NOL carryover from the 2022 income before NOL deduction.
Given Income (Loss) Before NOL Deduction:
2017: $(50,000)
2018: $30,000
2019: $(20,000)
2020: $40,000
2021: $(60,000)
Total Income (Loss) Before NOL Deduction = $(50,000) + $30,000 - $(20,000) + $40,000 - $(60,000) = $(60,000)
If the NOL carryover is $80,000, deduct this from the 2022 income before NOL deduction:
2022 Taxable Income After NOL Deduction = Income Before NOL Deduction - NOL Carryover
2022 Taxable Income After NOL Deduction = $(60,000) - $80,000 = $0
b. The 2022 book-tax difference associated with the NOL is favorable and temporary. It's favorable because it reduces taxable income to zero, resulting in no tax liability. It's temporary because the NOL deduction impacts taxes for the current year but will not carry forward or backward after the NOL amount is fully utilized.
