Answer 1

Answer :

B.

$15,603

Half of self employment tax = Business income * half of self employment tax rate = $400,000 * 7.65% = $30,600.

Modified adjusted gross income = adjusted gross income + business income + half of self employment tax = $180,000 + $400,000 + $30,600 = $610,600.

The threshold for net investment income tax for single is $200,000.

Amount subject to net investment income tax = Modified adjusted gross income - threshold for net investment income tax for single = $610,600 - $200,000 = $410,600.

Net investment income tax = amount subject to net investment income tax * net investment income tax rate = $410,600 * 3.8% = $15,602.80 or $15,603 (rounded off).

(Half of self employment tax rate = self employment tax rate / 2 = 15.3% / 2 = 7.65%).
