Answer:
Maui Resort Inc. 
 
Journal Entry: 
 December 31, 2020: 
 Debit Loss from Unrealizable DTA $31,000 
 Credit Allowance for Unrealizable DTA $31,000 
 To record the expected loss from unrealizable DTA and to increase the Allowance balance to $35,000. 
 
Step-by-step explanation: 
 a) Data and Calculations: 
 December 31, 2020 Deferred Tax Asset (DTA) = $50,000 
 Estimate of realizable DTA = 30% of $50,000 = $15,000 
 Allowance for unrealizable DTA for 2020 = 70% of $50,000 = $35,000 
 Loss from unrealizable DTA = $31,000 ($35,000 - $5,000) 
 
b) We can liken the Allowance for Doubtful Accounts to the DTA Valuation Allowance, which is a contra-account to the Deferred Tax asset Account. In it, the amount of the deferred tax asset that has a more than 50% probability of being lost or unutilized in the future arising from non-availability of sufficient future taxable income is accounted for.
