Economist magazine argues against tax-deductible debt
The May 16, 2015 cover story for Economist is “Tax-free debt: The great distortion.” The article advocates one of my personal pet ideas: eliminate tax deductions for home mortgage interest (see “Most perverse things about the U.S. tax code?” for example), though not for all of the reasons that I am against subsidizing home ownership, e.g., that it makes the labor market more rigid and exposes consumers to risks such as Detroit or Chicago becoming insolvent. The Economist goes farther, however, and suggests eliminating deductions for business interest. Could that work? Consider an equipment leasing company. After depreciation, interest would presumably be its largest expense. At current U.S. corporate income tax rates the enterprise would owe more in taxes than its actual cash earnings. Thus leasing companies couldn’t exist in their present form or with anything like their existing rates.
I can’t quite figure out if this makes sense as an economic policy. If interest is not deductible, doesn’t that favor the largest enterprises that can borrow at the lowest costs? So if you’re a mid-sized business trying to compete with General Electric, you’re now at a further disadvantage because GE can borrow at much lower cost than you and then offer favorable lease rates for its products, an effect magnified by the lack of deductibility for your higher payments. If interest is not deductible then incumbent companies with large capital bases will be further advantaged compared to startups? Supposedly there are economists at the Economist but I can’t figure out why interest, a necessary expenses for many types of businesses, should be treated differently than other types of business expense. (The home mortgage situation is different, I think, because that’s a personal expense and generally personal expenses are not deductible.)
[Separately, the research behind the article is a little suspect for saying “America’s debt subsidies cost the federal government over 2% of GDP—as much as it spends on all its policies to help the poor.” To the extent that you believe elaborate medical interventions “help the poor,” this is wrong. Federal Medicaid spending alone is close to 2% of GDP (gao.gov; this is not the total spent on Medicaid, I don’t think, because it excludes what states spend). How could the editors have missed the fact that the U.S. is a country with tens of millions of working-age residents who don’t work and yet who don’t lack for the essentials (housing, food, health care) and that this could not be consistent with only a few percent of GDP captured by the poverty industry?]
