Week in Insights: US Could Learn From Axed Swiss Rental-Value Tax

Oct. 5, 2025, 2:00 PM UTC

Until recently, Swiss residents who lived in the homes they owned were taxed as if they were earning rent from themselves under the country’s imputed rental-value tax.

The idea was to treat owner-occupiers and renters equally under the tax code, with the former needing to account for the benefit of living rent-free in their home. It may sound bizarre, but it isn’t any more irrational than the US mortgage-interest deduction.

The US approach, however, is basically the opposite of what Switzerland was doing. We reward homeownership and peg the size of that reward to the size and rate of the mortgage undertaken to acquire the home—the more interest you pay, the more benefit you receive. Renters, of course, get nothing.

The Swiss approach was built on the economic principle of tax neutrality. It treated the implicit rental benefit of owner-occupied housing as income and allowed mortgage interest deductions only as an offset to that hypothetical income.

Voters decided last month to abolish the tax. This will simplify filing and ease burdens on homeowners, but it also erases a powerful tool for achieving tax equity.

The US hasn’t seriously considered something similar, which tells you everything you need to know about our housing policy priorities. We want to encourage homeownership, full-stop—and we don’t mind placing renters at an economic disadvantage to do so.

Subsidizing homeowners simply because they borrowed money to purchase their home isn’t sound policy, though. We should consider offsetting that deduction with imputed income. If the Swiss are done with tax neutrality, maybe we can take it off their hands.
