Another excellent article appeared yesterday in the New York Times regarding the home mortgage interest deductionThe mortgage interest deduction is an itemized deduction for interest paid on home mortgages. It reduces households’ taxable incomes and, consequently, their total taxes paid. The Tax Cuts and Jobs Act reduced the amount of principal and limited the types of loans that qualify for the deduction. , this time detailing its history and why most economists argue that it is bad taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. policy. Roger Lowenstein explains the historical context of the deduction:
The first modern federal income tax was created in 1894. Interest — all forms of interest — was deductible; the Supreme Court, however, quickly ruled that the tax was unconstitutional. In 1913, the Constitution was amended and a new income tax was enacted. Once again, interest was deductible.
There is no evidence, however, that Congress thought much about this provision. It certainly wasn’t thinking of the interest deduction as a stepping-stone to middle-class homeownership, because the tax excluded the first $3,000 (or for married couples, $4,000) of income; less than 1 percent of the population earned more than that. The people paying taxes — Andrew Carnegie and such — did not need the deduction to afford their homes or their yachts.
There is another reason Congress could not have had homeownership in mind. The great majority of people who owned a home did not have a mortgage. The exceptions were farmers. But most folks bought their homes with cash; they had no mortgage interest to deduct.
When Congress made interest deductible, it was probably thinking of business interest. Just as today, the aim was to tax a business’s profits after expenses had been netted out, and interest was an expense like any other. In a nation of small proprietors, basically all interest looked like business interest. Whether it was interest on a farm mortgage, or interest on a loan to purchase a tractor, or interest charged to a general store that purchased its inventory on credit, it all would have looked like a business expense. Credit cards did not exist. So Congress just said, “Deduct it.”
It was not until the 1920’s and the spread of the automobile that home mortgages outnumbered farm mortgages. In the 1930’s, the mortgage industry got a huge assist from the feds — not from the tax deductionA tax deduction is a provision that reduces taxable income. A standard deduction is a single deduction at a fixed amount. Itemized deductions are popular among higher-income taxpayers who often have significant deductible expenses, such as state/local taxes paid, mortgage interest, and charitable contributions. , but from agencies like the Federal Housing Administration, which insured 30-year loans, and, over time, the newly created Federal National Mortgage Association, or Fannie Mae. Before then, the corner bank would issue a mortgage and wait for the homeowner to pay them back; now savings and loans could replenish their capital by selling their mortgages to Fannie Mae — meaning they could turn around and issue a new mortgage to someone else.

The article is right – the mortgage interest deduction essentially treats individuals’ housing expenses like a business expense, allowing them to deduct it from taxable incomeTaxable income is the amount of income subject to tax, after deductions and exemptions. For both individuals and corporations, taxable income differs from—and is less than—gross income. . But the big difference between a business deducting interest and an individual deducting housing-related interest is that the business must pay taxes on the net income for which that expense was incurred, whereas no one pays tax on the imputed income they earn from owning a home.
