Answer:
a. 1,260
b. $1,680
Explanation:
a. The computation of contribution needed is shown below:-
Contribution needed = Balance needed to qualify for 4.6% rate - Actual balance
= $18,700 - $17,440
= $1,260
b. The computation of tax savings realized is shown below:-
Tax savings realized = Tax without voluntary contribution - Tax with voluntary contribution - Amount of voluntary contribution
($980,000 × 4.9%) - ($980,000 × 4.6%) - $1,260
= $48,020 - $45,080 - $1,260
= $1,680
