Answer:
$162,500
Step-by-step explanation:
Notice that 2 things have happened to date due to the difference in the way net income is computed normally and how it is computed for tax purposes, which is the temporary difference the question is alluding to:
Step 1. Income to date based on percentage completion
Year 2 - $300,000
Year 3 - $600,000
Year 4 - $850,000
Total $1,750,000
Step 2. Taxable income to date based on completed contract
Year 3 - $400,000
Year 4 - $700,000
Total $1,100,000
Step 3. Computation of Temporary Difference
The temporary difference = Net Income - Taxable Income.
Hence Temporary Difference = $1,750,000 - $1,100,000 = $650,000
Therefore, Deferred Income Tax liability = Tax rate x Temporary difference
Deferred Income Tax liability = 25% x $650,000 = $162,500
