The $69 billion mortgage interest deduction (MID) is often viewed as an element of the tax code that promotes middle-class prosperity. However, 64 percent of the benefits, as measured by effective tax reduction, goes to households earning more than $100,000 per year. The large variation in nominal benefits is one of the reasons why many economists state that the MID is regressive. High-income earners average a tax benefit nearly nine times greater than a tax filer earning $50,000-$100,000. The effective tax reduction of the MID per return among tax filers earning between $100,000 and $200,000 is $1,420. That is still nearly 10 times larger than the $150 saved by taxpayers earning between $30,000 and $50,000. With 65.2 percent of all tax filers claiming to make less than $50,000, only 9.8 percent of these returns used the mortgage interest deduction. In order to create a simpler, more efficient tax code, policymakers should take care to effectively align tax policy with housing objectives.
