The Foreign-Rental Depreciation Playbook: ADS, Cost Segregation and Recapture for U.S. Owners
Published on: July 20, 2026
Last reviewed: 20 July 2026. Depreciation rules and recovery periods are technical and periodically amended; confirm the current position for your facts and tax year.
If you're a U.S. citizen or green-card holder who rents out a property abroad, depreciation is one of the most valuable deductions you have, and one of the most commonly botched. The rules for foreign property are genuinely different from domestic ones, and two of the most popular pieces of "tax-saving" advice you'll read online are simply wrong when the property sits outside the United States.
Two corrections up front, because they reverse the usual assumptions:
- It's not "40 years" for your rental. Foreign residential rental placed in service after 2017 depreciates over 30 years, not 40. The 40-year figure is for commercial property.
- You cannot take bonus depreciation, not even after the 2025 tax law brought 100% bonus back. Foreign property is locked out of it entirely.
Get these right and you'll deduct more, plan your eventual sale properly, and avoid the nasty surprise that catches owners who assumed foreign property works like a rental in Texas. Here's the full playbook.
Key facts at a glance
- Foreign rental property must use the Alternative Depreciation System (ADS): straight-line, no acceleration.
- Residential: 30 years (placed in service after 31 Dec 2017); commercial: 40 years. Compare with 27.5 years for U.S. domestic residential.
- No bonus depreciation and no Section 179 for foreign property: the ADS requirement blocks both, and the 2025 OBBBA restoration of 100% bonus does not change this.
- Cost segregation still works abroad, but only shifts components into longer ADS lives (often 9–12 years, not 5–7) with no first-year write-off.
- On sale, depreciation recapture applies the same as domestic: unrecaptured §1250 gain taxed up to 25%, and §1245 ordinary-income recapture on any cost-segregated personal property.
- You report on Schedule E and Form 4562, in U.S. dollars, and generally claim the Foreign Tax Credit (Form 1116) for foreign tax paid.
Why foreign property is on a different system
U.S. tax law makes you report your worldwide income, so rent from a flat in Lisbon or a villa in Bali lands on your U.S. return whether or not you ever remit it home. But when the property is used predominantly outside the United States, the tax code requires it to be depreciated under the Alternative Depreciation System (ADS) rather than the faster General Depreciation System (GDS) that domestic rentals use.
ADS means two things: straight-line depreciation (equal amounts each year, no front-loading) and longer recovery periods. That's the core of every difference that follows.
The recovery periods:
| Property | System | Recovery period |
|---|---|---|
| U.S. domestic residential rental | GDS | 27.5 years |
| Foreign residential rental (in service after 2017) | ADS | 30 years |
| Foreign commercial property | ADS | 40 years |
A note on timing: the shift to 30 years for foreign residential rental came in with the 2017 tax reform, effective for property placed in service on or after 1 January 2018. Property placed in service before 2018 was generally on the old 40-year schedule (with narrow exceptions later introduced for electing real-property businesses). So the very first thing to confirm on any foreign rental is the date it was placed in service, it determines your recovery period, and using the wrong one distorts every year of your return.
And the basics still apply: you depreciate the building, not the land (land never wears out, so you must allocate the purchase price and strip out land value), and every figure goes on your return in U.S. dollars at the appropriate exchange rate.
The bonus-depreciation myth (this is the big one)
Here's where most online advice steers foreign owners wrong. In 2025, the tax law known as the One Big Beautiful Bill Act (OBBBA) restored 100% bonus depreciation on a permanent basis for qualifying property acquired and placed in service after 19 January 2025. Cue a wave of articles promising huge first-year write-offs.
For foreign real estate, none of it applies.
Bonus depreciation is only available for property that is not required to use ADS. Because foreign-use property is required to use ADS, it is excluded from bonus depreciation, and OBBBA didn't touch that exclusion. The same logic knocks out Section 179 expensing: you generally cannot immediately expense equipment or furnishings for a foreign rental either; you depreciate them over their applicable ADS lives.
So no matter how many domestic-focused articles you read about "100% bonus," the answer for your overseas rental is the same as it was before: straight-line, over the full recovery period, no first-year acceleration. Assuming otherwise is one of the most common (and most expensive) filing errors on expat returns.
Cost segregation abroad: still useful, but not the machine it is at home
Cost segregation is the strategy of breaking a building into its components, personal property (appliances, furniture, certain fixtures) and land improvements (paving, landscaping, fencing), so those components depreciate faster than the 30- or 40-year building shell. Domestically, cost seg is powerful precisely because you can then layer bonus depreciation on the short-life components and write off a large chunk in year one.
Abroad, the strategy still exists, but its most powerful feature is gone, and the mechanics are muted:
- No bonus depreciation on the segregated components. You can't write off the furniture or the HVAC in year one just because you've carved it out of the building. You still depreciate each item over its life.
- The "short" lives aren't that short. Under ADS, components that would be 5-, 7-, or 15-year property domestically carry longer ADS recovery periods, often around 9–12 years for personal property and 20+ years for many land improvements. So cost seg moves cost from the 30/40-year bucket into (say) a 10-year bucket, a real acceleration, but nothing like the dramatic front-loading you'd get at home.
When it can still be worth it: higher-value properties, and short-term-rental operations where more of the value sits in furnishings and equipment, can still see a meaningful lift in early-year deductions from an ADS-based cost segregation study. But the study has a cost, and the benefit is modest relative to a domestic study, so the numbers have to justify it. Run the analysis before commissioning one.
The sting on the way out: depreciation recapture
Depreciation isn't a free gift: it lowers your basis, which raises your taxable gain when you sell. And the character of that recaptured depreciation is where owners get caught. For foreign property, recapture works the same way it does domestically:
- The building depreciation you claimed comes back as "unrecaptured §1250 gain," taxed at a maximum federal rate of 25% (rather than the lower long-term capital-gains rate that applies to the rest of your gain). Because ADS is straight-line, there's no "excess" depreciation to recapture as ordinary income; it falls into this 25% category.
- Any cost-segregated personal property is §1245 property, and depreciation on it is recaptured as ordinary income on sale, up to the amount of depreciation taken.
That second point is the hidden trade-off of cost segregation: you accelerate deductions during ownership, but you convert some of your future gain from favourable capital-gains treatment into ordinary-income recapture at exit. Whether that trade is worthwhile depends on your rates now versus later and how long you'll hold, another reason cost seg abroad is a "do the math" decision, not an automatic yes.
And don't forget the currency layer. Your depreciation is fixed in U.S. dollars at historical exchange rates, while your sale proceeds convert at the future rate. Gain (and recapture) is computed in dollars, so exchange-rate movement between purchase and sale is baked into the result, sometimes helpfully, sometimes not.
A worked example
Take a $300,000 foreign residential rental placed in service in 2026, with $60,000 of that allocated to land.
- Depreciable basis: $240,000 (building only).
- ADS residential recovery period: 30 years, straight-line.
- Annual depreciation: roughly $8,000 per year ($240,000 ÷ 30).
Had this been a domestic rental at 27.5 years, the deduction would be about $8,727 per year, modestly higher. And had bonus depreciation or a bonus-charged cost-seg study been available (it isn't, abroad), the year-one figure could have been dramatically larger. This is the concrete cost of the ADS rules: a smaller, slower deduction than an equivalent U.S. property, with no first-year lever to pull.
Now fast-forward to a sale years later: the total depreciation you claimed reduces your basis, and that portion of the gain is taxed as unrecaptured §1250 gain at up to 25%. Plan for it; it's not a surprise if you've read this far.
(Figures are illustrative and rounded to show the mechanics; conventions such as the mid-month rule and your specific facts will change the exact numbers.)
Getting it onto the return, and avoiding double tax
- Where it goes: foreign rental income and expenses are reported on Schedule E, with depreciation calculated on Form 4562.
- Foreign Tax Credit: you generally claim a credit for income tax paid to the foreign country on Form 1116, which is the main mechanism preventing you from being taxed twice on the same rental income.
- Watch the reporting web: holding the property through a foreign entity can pull in additional forms (for example, foreign-disregarded-entity reporting), and foreign accounts tied to the property may trigger FBAR/FATCA filings. Passive-activity-loss rules can also limit how quickly you actually benefit from these deductions.
- Consistency matters: once you've adopted a depreciation method and period, you generally can't just switch; changes typically require IRS consent via an accounting-method change. Getting the recovery period right in year one is far easier than fixing it later.
Because of all this, foreign rental returns are genuinely more complex than a domestic Schedule E, and the cost of an error compounds over every year of ownership. This is an area where a tax professional who specialises in expat/international returns usually pays for themselves.
Frequently asked questions
Is my foreign rental depreciated over 30 or 40 years?
Residential: 30 years if placed in service after 2017 (older properties may be on 40). Commercial: 40 years. Both use ADS straight-line. Confirm the placed-in-service date first, it decides the period.
Can I take 100% bonus depreciation on my foreign property now that OBBBA restored it?
No. Foreign-use property must use ADS, which excludes it from bonus depreciation, and OBBBA didn't change that. Section 179 expensing is generally unavailable too.
Does cost segregation work on foreign property?
Yes, but with muted benefit: it shifts components into longer ADS lives (often ~9–12 years) with no first-year write-off. It can still help on high-value or furnishing-heavy properties, but the numbers must justify the study's cost.
Do I have to depreciate at all?
Depreciation isn't optional in the sense you might hope: the IRS computes recapture on sale based on depreciation "allowed or allowable," meaning you can face recapture on depreciation you should have claimed even if you didn't. Claiming it correctly is almost always better than skipping it.
What happens to depreciation when I sell?
It reduces your basis and increases gain. Building depreciation is unrecaptured §1250 gain (max 25%); any cost-segregated personal property triggers §1245 ordinary-income recapture. The same rules as domestic property.
How do I avoid being taxed twice?
Claim the Foreign Tax Credit (Form 1116) for income tax paid to the property's country, and check whether an income-tax treaty affects the result.
The bottom line
Foreign rental depreciation rewards owners who understand that they're on a different system, and quietly punishes those who assume it works like a U.S. rental. The recovery periods are longer (30 residential / 40 commercial), the deduction is straight-line, and the two headline "accelerators" (bonus depreciation and Section 179) are simply off the table, OBBBA or not. Cost segregation survives but in a muted form, and it comes with a recapture trade-off you should price in before commissioning a study. Nail the placed-in-service date, get the recovery period right in year one, plan for §1250/§1245 recapture on exit, and claim your Foreign Tax Credit, and this becomes a reliable, well-understood deduction rather than a landmine.
