Answer: $18,000
Step-by-step explanation:
Interest from municipal bonds is tax free and will therefore result in a permanent difference along with the premium on officers' insurance.
Temporary difference will arise from the estimated future warranty costs to be paid in Year 2 and 3 and this will be a tax benefit because they will only be recognized in Year 2 and 3 but have already been recognized by the tax authority:
= 60,000 * 30%
= $18,000
