How to approach this question

1. Identify the NIIT threshold for Single filers: $200,000.<br/>2. Calculate Excess MAGI: $220,000 - $200,000 = $20,000.<br/>3. Identify Net Investment Income (NII): $40,000.<br/>4. Determine the tax base: Lesser of NII ($40,000) or Excess MAGI ($20,000). Base = $20,000.<br/>5. Calculate Tax: $20,000 * 3.8%.

Full Answer

B.$760✓ Correct
B
NIIT Base = Lesser of (a) NII ($40,000) or (b) MAGI - Threshold ($220,000 - $200,000 = $20,000).<br/>Base = $20,000.<br/>Tax = $20,000 * 3.8% = $760.

Common mistakes

Applying the 3.8% tax to the entire NII amount without checking the MAGI excess limitation.
