Final answer:
Santini's taxable income for 2022 is $131,970 after accounting for benefits, stock grant vesting, and 401(k) contributions. His income tax liability, calculated using the provided tax rate schedules, amounts to $33,120.
Step-by-step explanation:
To determine Santini's taxable income for 2022, we need to add up all of his income and benefits and then adjust them based on their taxability. Santini's total compensation from different sources includes a basic salary, health insurance, a restricted stock grant, a bonus, a non-cash benefit from a Hawaii trip, group-term life insurance, and paid parking.
-
- Salary: $130,000
-
- Health insurance: $9,000
-
- Restricted stock grant: (500 shares * $7.50 market price) - (500 shares * $5 grant price) = $1,250 taxable benefit
-
- Bonus: $5,000
-
- Hawaii trip: $4,000
-
- Group-term life insurance: $1,600
-
- Parking: $3,720
Before the employer's match on his 401(k) contribution, Santini's gross income is $130,000 (salary) + $5,000 (bonus) + $4,000 (Hawaii trip) + $1,250 (net taxable restricted stock grant) + $3,720 (parking) = $143,970. Assuming that Santini contributes at least $6,000 to his 401(k), which is matched by the employer, his taxable gross income, before retirement contributions, would be $137,970. After subtracting the $6,000 401(k) contribution, Santini's net taxable income would be $131,970.
Now, we'll apply the tax rate schedules to calculate his income tax liability:
-
- Up to $50,000: $7,500 tax
-
- $50,000 to $75,000: $13,750
-
- Above $75,000: $131,970 - $75,000 = $56,970, 34% on this amount = $19,369.80
Add up these parts gives us: $7,500 + $6,250 (25% of the amount over $50,000) + $19,369.80 = $33,119.80, which is Santini's total tax liability for 2022, rounded to the nearest whole dollar: $33,120.
