Practice questions using Net Investment Income Tax

Original questions written against the published FINRA and NASAA exam content outlines — not actual exam questions. Every choice is explained.

Qualified cash dividends received by an individual investor are generally taxed at...

  1. A.Long-term capital gains ratesCorrect — qualified dividends are taxed at the favorable long-term capital gains rates.
  2. B.A flat 50 percent rateNo such flat dividend rate exists.
  3. C.They are always tax-freeQualified dividends are taxed, just at lower rates.
  4. D.Ordinary income rates in every caseOnly nonqualified dividends are taxed as ordinary income.

Why: Qualified dividends are taxed at the lower long-term capital gains rates rather than at ordinary income rates, provided holding-period requirements are met.

A candidate assumes a BDC must pay corporate income tax on its net investment income before any of it reaches shareholders, the same as an ordinary C corporation. Why is this generally not the practical result?

  1. A.Because a BDC is legally a partnership even though it is called a company.Wrong. A BDC is legally organized as a corporation, not a partnership; its favorable tax result comes from the regulated investment company election, not from partnership status.
  2. B.Because BDC income is exempt from federal taxation entirely, at both the entity and shareholder level.Wrong. BDC income is not tax-exempt; shareholders are taxed on the dividends they receive, and the entity itself avoids tax only to the extent it distributes income and qualifies for the dividends-paid deduction.
  3. C.Because a BDC that qualifies and elects regulated investment company treatment gets a deduction for dividends paid, which offsets the income it distributes and avoids tax at the fund level.Correct. The regulated investment company election gives a qualifying BDC a deduction for dividends paid, offsetting distributed income and avoiding double taxation at the fund level.
  4. D.Because a BDC's losses from borrower defaults exceed its income in most years, leaving no taxable income at the entity level.Wrong. The favorable result depends on the RIC election and distribution requirement, not on losses happening to exceed income.

Why: A BDC is organized as a corporation, so the instinct to apply ordinary double-taxation logic is understandable, but a BDC that qualifies as and elects regulated investment company treatment is entitled to a deduction for dividends paid to shareholders. Distributing substantially all of its net investment income lets the BDC offset that income with the deduction and avoid meaningful tax at the entity level, so shareholders are effectively taxed once, on the dividends they receive, similar to how a mutual fund passes income through. This is different from a limited partnership's true pass-through of both income and losses, but it also is not the double taxation a plain C corporation faces.

A high-income DPP investor owes both additional tax from the alternative minimum tax system and additional tax from the net investment income tax (the 3.8% surtax on certain investment income) in the same year. How do these two additional taxes relate to each other?

  1. A.They are the same tax under two different names; a taxpayer who owes AMT automatically owes an equal amount of net investment income tax and vice versa.Wrong. AMT and the net investment income tax are separate, independently computed taxes; owing one does not imply owing an equal amount of the other.
  2. B.The net investment income tax is simply a component included within the AMT computation, not a separate tax.Wrong. The net investment income tax is computed under its own separate provision; it is not folded into the AMT computation.
  3. C.They are two entirely separate tax systems, computed independently under different code provisions, and both can apply to the same taxpayer in the same year on top of regular tax; paying one does not offset or substitute for the other.Correct. AMT and the net investment income tax are independent systems that can both apply in full to the same taxpayer in the same year.
  4. D.Whichever of the two produces the larger liability is owed, and the smaller one is waived, similar to how AMT itself works against regular tax.Wrong. Unlike the regular-tax-versus-AMT comparison, AMT and the net investment income tax are each owed in full; they are not compared and reduced to the larger of the two.

Why: AMT and the net investment income tax are two entirely separate tax systems, computed independently under different code provisions, and both can apply to the same taxpayer in the same year on top of regular tax; paying one does not offset or substitute for the other.

Assume the net investment income tax is 3.8 percent and is imposed on the LESSER of net investment income or the excess of modified adjusted gross income over a 200,000 dollar threshold for a single filer. Lucinda Prewitt is single, with 210,000 dollars of wages and 40,000 dollars of net investment income, giving her modified adjusted gross income of 250,000 dollars. What is her net investment income tax?

  1. A.950 dollarsThis applies the rate to 25,000 dollars, which is neither of the two candidate figures.
  2. B.1,900 dollarsThis taxes the 50,000 dollar excess over the threshold rather than the smaller of the two amounts.
  3. C.9,500 dollarsThis applies the rate to her entire modified adjusted gross income, including wages, which are never subject to this tax.
  4. D.1,520 dollarsCorrect. 3.8 percent of the lesser figure, 40,000 dollars of net investment income.

Why: Two figures are compared and the smaller is taxed. Her net investment income is 40,000 dollars. Her modified adjusted gross income exceeds the stated 200,000 dollar threshold by 50,000 dollars. The lesser of the two is 40,000 dollars, and 3.8 percent of 40,000 dollars is 1,520 dollars. Wages themselves are never subject to this tax; they matter only because they push modified adjusted gross income above the threshold and thereby expose the investment income.
