One of the first articles I published as an academic was on the kiddie tax. It was a sleepy corner of the tax world; most of the academic literature on the kiddie tax came from the 1980s.[fn1] And, for its first three decades, the kiddie tax stayed almost exactly the same.[fn2] Then, in a little-noticed provision of the TCJA, Congress fundamentally changed the kiddie tax. In response, I addressed the kiddie tax a second time in a piece for Tax Notes entitled Meet the New “Kiddie Tax”: Simpler and Less Effective. [Paywall] It turns out that I underestimated the ways in which is was not only less effective, but actually dangerously counterproductive.
But first, a quick primer into what the kiddie tax was and what it has become. In 1986, Congress had become worried that wealthy taxpayers were shifting income-producing assets to their children so that they could lower their tax bills. The tax game would go something like this: wealthy dentist father gives (or, I suppose, sells for a nominal amount) his x-ray machines to his 7-year-old daughter. He then leases back the x-ray machines for, let’s say, $10,000 a year. In 1985, the top marginal tax rate was 50%. Assuming our dentist was in that tax bracket, he could deduct the $10,000 he paid to lease the x-ray machines. Meanwhile, assuming that his 7-year-old daughter didn’t have any additional income, she would have been in the 16% tax bracket. According to Rev. Proc. 84-79 (and ignoring any exemptions or deductions she might have), the daughter would pay taxes of $1,054 on the $10,000 of income. Meanwhile, Dad’s $10,000 deduction saved him $5,000 in taxes. By shifting passive income to his daughter, then, Dad saved almost $4,000.[fn3] (Note that it didn’t have to be dental equipment: it could be any income-producing property).
