Answer:
a. Taxable income coming from short term
= $102,000 + $5,000 + ($10,000 - $7,500) = $109,500
b. Taxable income coming from long term & dividends
= $750 + $16,000 + ($17,000 - $8,000) = $25,750
dividends are taxed as ordinary income, only long term capital gains are taxed at 15%
c. Total Federal Tax owned
ordinary income = $126,250 - $12,000 = $114,250
long term capital gains = $9,000
ordinary tax liability = $14,089.50 + [24% x ($114,250 - $82,500)] = $21,709.50
long term capital gains = $9,000 x 15% = $1,350
total tax liability = $23,059.50
d. Marginal Tax rate
24%
e. Average Tax rate
$21,709.50 / $114,250 = 19%
