Despite the headline, I read the commentary. It turned out that the headline was the least of my concerns.
In the commentary, Tom Giovanetti praised the Supreme Court’s decision not to hear the challenge. He pointed out that the four states bringing the challenge – Connecticut, Maryland, New Jersey, and New York – are “four solid ‘blue,’ high-tax states.” He explained that before the limitation was enacted, “the federal tax code essentially subsidized high-tax blue states.” He asked, “Why care about your state’s high taxes if you can just deduct them all from your federal taxes?” The answer to his question is easy. If a person in facing a marginal 35 percent federal income tax rate is hit with a $1,000 increase in state taxes, it’s not as though the person’s federal income tax liability is reduced by $1,000. If it were, then it would be true that the person would not care about the increase. Rather, the $1,000 increase means that the person would be $650 out of pocket. Most people would care about that.
Worse, though, is the jab at high-tax “blue” states getting federal subsidization of state and local taxes and the implicit praise for the $10,000 limitation. Yet that is only a small piece of federal subsidization of states. A careful analysis of the relationship between federal and state taxes and subsidies tells a different story. As recently disclosed by various reports, including Wallet Hub, Money Geek, and Forbes, the overall picture is different. It’s a pattern that reaches back many years, as indicated, for example, in 2004 by the Tax Foundation as summarized in this TaxProf blog post. The most recent analyses disclose that eight of the ten states most dependent on federal government funding are red states. Of the nine states that sent more to the federal government in taxes than they received from the federal governent, seven were blue states, which also had higher per-capita GDPs than many of the red states near the top of the federal subsidy list. The eight states receiving the highest child tax credit per capita are red states. Attempts to dismiss these findings, such as this Hill commentary by an ALEC member muddies the analysis by pointing out that the top ten federally dependent states are not all red, that two red states are actually blue states, and that it makes sense for red states to be subsidized by blue states because blue states have higher per-capita GDPs and red states are most in need. The latter observation is, to me, an indictment of how the classic red-state low-tax, low-service (and less pervasive education) approach shortchanges its citizens.
Giovannetti does make an important point. He notes that the $10,000 limitation should be indexed for inflation. He is correct. He then proposes that both the limitation and “capital gains taxes” be indexed for inflation. I’m not sure whether he means that the tax liability on capital gains should be indexed or if capital gains should be indexed, but perhaps he means that taxpayers’ adjusted bases in capital assets should be indexed. If that is what he means, I agree. However, if capital asset adjusted basis is indexed then the justification for low rates on capital gains (and the limitation on the deduction of capital losses) disappears. The latter were enacted as admittedly rough solutions to the capital asset inflation problem. Pick one. Keeping both is excessive.
One of the articles I haven’t yet written, and perhaps never will, is one that rests on a list of dollar amounts in the Internal Revenue Code that are indexed for inflation and those that are not. Both lists are long, both keep growing, and I’ve not yet found or made the time to once again read the entire Internal Revenue Code to identify each provision in the two lists. Perhaps someone has done this sort of comprehensive survey with respect to the Internal Revenue Code as it exists for 2022; J.K. Lasser has a long list of some of the limitations not adjusted for inflation. Of course, some limitations not indexed for inflation immediately jump to mind even without looking at the list, such as the $250,000 and $500,000 limitations on the exclusion for gains from the sale of a personal residence, the base amounts and adjusted base amounts used in computing the portion of social security benefits included in gross income, the $25 deduction for business gifts, and the $5,250 exclusion for employer-provided education assistance. If the $10,000 limitation on the deduction for state and local taxes and the adjusted bases of capital assets are to be indexed, then so, too, should all of the other fixed dollar amounts in the Internal Revenue Code. That would advance the notion of tax fairness by helping not only the well-to-do who pay higher state and local income taxes and enjoy the ownership and sale of capital assets, but also the social security recipients with lower income and home sellers facing very high amounts of gain because of a housing market bubble but who otherwise have modest amounts of income.
When Giovannetti proposed increasing those two limitations, he asked, “Any takers?” If he included all fixed dollar amounts and not just those two, and agreed to dispose of the low capital gains rate and capital loss limitation band-aids, then I’m on board. For that idea, there isn’t any red or blue.
