Dmitri and Lena pay tax at a 35 percent marginal rate and want to shift investment income to a lower bracket family member. They plan to give a bond portfolio to their daughter, aged 16, who is their dependant and has no earned income. The portfolio is expected to pay 9,000 dollars of interest in the coming year and she has no other income. Assume that for a dependent child the first 1,350 dollars of unearned income is exempt, the next 1,350 dollars is taxed at the child's own rate, and unearned income above 2,700 dollars is taxed at the parents' marginal rate. How much of the 9,000 dollars would be taxed at 35 percent?
- A7,650 dollars, being the interest above the 1,350 dollar exempt amount.
- B6,300 dollars, being the interest above the 2,700 dollar unearned income threshold. Correct
- C9,000 dollars, because a dependent child pays her parents' rate on unearned income.
- DNothing, because the kiddie tax reaches only a child aged under 14 at the year end.
Why A is wrong: This subtracts only the exempt band and hands everything else to the parents' rate. It is wrong because it overlooks the second 1,350 dollar band, which is taxed at the daughter's own low rate before the parents' rate is reached.
Why B is correct: The first 1,350 dollars is exempt and the next 1,350 dollars is taxed at the daughter's own rate, so 2,700 dollars escapes the parents' rate. The remaining 9,000 minus 2,700, that is 6,300 dollars, is taxed at the parents' 35 percent marginal rate.
Why C is wrong: It is tempting to read the kiddie tax as switching the whole of a child's unearned income to the parents' rate. It is wrong because the rule applies only to unearned income above the stated threshold, leaving the first 2,700 dollars taxed at the exempt amount and at the child's own rate.
Why D is wrong: The age 14 limit is a rule that was superseded years ago, which is why candidates who learned it once still pick this. It is wrong because the kiddie tax now covers a child under 18, and a full time student under 24 whose earned income does not exceed half of her support.
