Answer: $1,824
Step-by-step explanation:
According to the IRS, Net Investment Income tax is the lesser figure of either,
i. The net investment income or,
ii. Modified adjusted gross income less the threshold of $200,000 of the person.
The lesser figure is then multiplied by 3.8% to find the tax.
Alain Mire's net Investment Income is $48,000.
His Modified adjusted gross income less the threshold of $200,000 is,
= 309,000 - 200,000
= $109,000
The lesser figure is his Net Investment Income so Additional Tax is,
= 48,000 * 3.8%
= $1,824
