The short version: two countries, one rental property
Switzerland taxes your rental income at the federal, cantonal, and communal levels, and the US taxes your worldwide income. Instead of double taxation, you report the same rent on Schedule E in US dollars, depreciate the building over 30 years under the US Alternative Depreciation System, and claim the Swiss tax you paid as a foreign tax credit in the passive basket on Form 1116. If you're still deciding whether to buy, the purchase process has its own cross-border rules — see our guide to buying a home in Switzerland as a US citizen.
What Switzerland taxes and what you can deduct
Swiss rental income is taxable at all three levels: federal, cantonal, and communal. That includes short-term rental income such as Airbnb stays, and even ancillary costs your tenants reimburse, such as heating and water. Against that income, you can deduct the costs of earning it.
- Mortgage interest in full — but not principal repayment, which is amortization.
- Maintenance and repair costs — either actual documented costs or a cantonal lump-sum each year.
- Property insurance, including fire and natural-hazard coverage.
- Third-party property management costs.
- Certain energy-saving investments.
Owner-occupied changes don't touch rented property
The 28 September 2025 Swiss vote to abolish imputed rental value for owner-occupied homes, effective 1 January 2029, does not change how your rented-out property is taxed. Rental property retains its current federal, cantonal, and communal income treatment.
How the IRS taxes your Swiss rental income
For US purposes, foreign residential rental property is reported on Schedule E in US dollars, just like a domestic rental. Convert CHF to USD using the IRS yearly average exchange rate or the spot rate on the transaction date. Deductible US-side expenses mirror the Swiss list: mortgage interest, repairs and maintenance, property insurance, management fees, and local property taxes — but not principal payments. The interest-versus-principal distinction matters especially because Swiss lenders often structure mortgages with indirect amortization; see our guide to Swiss mortgage amortization for Americans.
Depreciation: you must use ADS, and yes, it's 30 years
Because the property is used predominantly outside the US, depreciation must use the Alternative Depreciation System, straight-line. For residential rental property placed in service after December 31, 2017, the recovery period is 30 years. For property placed in service before 2018, and for nonresidential or commercial property, it is 40 years. This is different from domestic residential rentals, which use a 27.5-year system. You never depreciate land — only the building. Depreciation is claimed on Form 4562 and flows to Schedule E.
You can't really 'skip' depreciation
If you do not claim depreciation, the IRS still treats it as if you had when you later sell: your basis is reduced and the gain may include depreciation recapture under Section 1250 at up to 25%. Claiming it now is generally the cleaner path.
Passive activity losses: why your Swiss loss may just carry forward
Rental real estate is generally a passive activity for US tax purposes. Passive losses offset only passive income; disallowed losses are suspended and carried forward on Form 8582. The special $25,000 allowance for active participation in rental real estate phases out between $100,000 and $150,000 of modified adjusted gross income and is generally not available if you claim the Foreign Earned Income Exclusion. As a result, most American expats in Switzerland cannot use that allowance and will carry Swiss rental losses forward to future passive income or sale.
Using Form 1116 to stop double taxation
Your Swiss rental income and the Swiss tax on it fall in the passive basket on Form 1116. The US-Switzerland tax treaty confirms this structure: Article 6 lets Switzerland tax income from Swiss real property, and Article 23 provides relief from double taxation through the foreign tax credit. Because US depreciation can push your US taxable rental income near zero, the Swiss tax paid can exceed the US tax on that same income and produce excess credits. Those excess credits can be carried back one year and forward ten years. The annual Swiss wealth tax on the property's net value is separate and generally not creditable on Form 1116; see our guide to Swiss wealth tax for Americans.
What changes when you sell
On sale, the US taxes the capital gain, and depreciation is recaptured. Switzerland does not impose a general federal capital gains tax on the sale of privately held real estate, but cantons levy a property gains tax with holding-period reductions. You generally claim a foreign tax credit for the Swiss gains tax. If the property is held through a Swiss company, different rules apply — including Form 5471 and controlled foreign corporation reporting — so that structure needs professional review before you commit.
Bank accounts and reporting: the rent lands somewhere
The real estate itself is not a financial account for FBAR or Form 8938 purposes. But the Swiss bank account that receives your rent is reportable if you meet the filing thresholds. Keep the ownership simple and the account documentation clean, and the reporting burden is manageable.
The bottom line
A rented Swiss property is not a tax trap, but it is a two-system commitment. Switzerland taxes the rent and allows real deductions; the US taxes the same rent but gives you depreciation and a foreign tax credit. The main planning issue for most expats is the passive-loss limitation, not double taxation itself. Understanding that one interaction is often the difference between quiet anxiety and a calm plan.

- Mortgage interest
- Fully deductible in Switzerland; deductible on Schedule E if attributable to the rental.
- Repairs and maintenance

- Depreciation
- Not a Swiss income tax item for this purpose; mandatory US ADS deduction over 30 or 40 years.
- Losses
- Swiss net loss may offset other Swiss income depending on canton; US passive losses generally suspended and carried forward.
- Swiss tax paid
- Creditable against US tax on the same passive income via Form 1116.
