Foreign investors can use cost segregation to accelerate depreciation on eligible components of U.S. rental property. The benefit depends on net-basis taxation and the ability to use the deductions. Cost segregation does not automatically reduce FIRPTA withholding when the property sells.
The practical question is how much tax the deductions can defer, after considering rental-tax elections, ownership structure, and the eventual sale.
Key takeaways
- Cost segregation identifies property components with shorter depreciation recovery periods.
- Eligible foreign owners can elect net-basis treatment for U.S. real-property income that is not otherwise effectively connected income.
- FIRPTA withholding generally equals 15% of the amount realized, not 15% of taxable gain.
- Eligible property acquired and placed in service after January 19, 2025 can qualify for 100% bonus depreciation.
- Depreciation recapture and loss limitations can change the value and timing of the benefit.
- Estate-tax valuations use fair market value, not the property's depreciated income-tax basis.
Can foreign investors deduct cost segregation depreciation?
Foreign owners can claim applicable depreciation deductions when their U.S. rental income receives net-basis tax treatment and deduction requirements are met.
Cost segregation identifies property components that qualify for shorter depreciation recovery periods than the building itself. The IRS cost segregation audit guide describes this cost-allocation process. A study allocates depreciable cost. It does not establish the owner's tax residency, create ECI, or determine fair market value.
Effectively connected income (ECI) is income connected, or treated as connected, with a U.S. trade or business. FDAP means fixed or determinable annual or periodical income.
U.S. rental income of a nonresident individual that is not ECI generally faces 30% gross-basis taxation, subject to applicable treaty provisions. Depreciation deductions are not available against that gross-basis tax. The IRS FDAP guidance distinguishes gross-basis taxation from taxation of ECI.
Eligible nonresident individuals can elect net-basis treatment under §871(d). Foreign corporations have a corresponding election under §882(d). These elections cover eligible U.S. real-property income that is not otherwise ECI. The real-property election regulation explains the election and associated deductions.
How do foreign owners elect net-basis taxation?
Eligible owners make the applicable election through a statement filed with their U.S. income tax return. Individuals use §871(d); foreign corporations use §882(d).
First determine whether the rental income is already ECI. An election is not always necessary. A study documenting management activity does not replace this analysis.
For individuals, Form W-8ECI documents the withholding position to the payer; it does not replace the election statement. See the IRS guidance for nonresident property owners.
Filing requirements also matter. Failure to file a timely return can jeopardize deductions. Have your adviser check the applicable return and election requirements before claiming depreciation.
ECI treatment also does not make every loss immediately deductible. Passive activity, basis, and at-risk limitations can restrict loss deductions for affected taxpayers. A suspended loss is not automatically a current refund.
Does cost segregation reduce FIRPTA withholding?
Cost segregation does not automatically reduce the standard FIRPTA withholding calculated on the amount realized when a foreign person sells U.S. real property.
FIRPTA withholding is a tax-collection mechanism on covered dispositions of U.S. real-property interests by foreign persons. It is not the final tax calculation.
The IRS FIRPTA rules generally require the buyer to withhold 15% of the amount realized. That amount can include cash, other property, and debt assumed by the buyer. Do not substitute the seller's cash equity or taxable gain.
| Question | Rental-income taxation | FIRPTA withholding at sale | Final tax on disposition |
|---|---|---|---|
| What is measured? | Gross income or net taxable income, depending on treatment | Generally the amount realized | Taxable gain, including applicable recapture |
| Where does depreciation matter? | Can reduce net taxable income when deductions are allowed | Does not change the standard percentage calculation | Reduces adjusted basis and can create recapture |
| What should the owner verify? | ECI status, elections, filing, and loss limits | Seller status, transaction rules, and certificates | Basis, asset allocations, and applicable tax treatment |
For example, assume a covered sale has a $5 million amount realized and no applicable exception or withholding certificate. Standard withholding would be $750,000. That remains the starting calculation even if taxable gain is much smaller.
A seller may apply for an IRS withholding certificate when required withholding exceeds the maximum tax liability. Approval is not automatic. Depreciation records help establish adjusted basis and recapture in the tax calculation supporting the application.
A qualifying buyer-residence transaction may be exempt when the amount realized does not exceed $300,000. The residence exception requires definite plans for the buyer or a family member to reside at the property.
Residence use must cover at least 50% of the days anyone uses the property. Apply that test separately during each of the first two 12-month periods after transfer. Vacant days are excluded from the denominator. A low sale price alone does not qualify.
How much can bonus depreciation change the first-year deduction?
Bonus depreciation can accelerate eligible component costs, but the tax benefit depends on eligibility, the owner's tax rate, and deduction usability.
The One Big Beautiful Bill Act (OBBBA) restored permanent 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025. Acquisition timing can depend on written binding contracts, not just closing. Earlier acquisitions follow separate legacy rules. IRS Notice 2026-11 provides the applicable rate and acquisition-date guidance.
Under IRC §168(k)(2), eligible MACRS property generally includes property with recovery periods of 20 years or less. Other requirements still apply. Property required to use the alternative depreciation system is excluded from bonus eligibility.
For context, review our explanation of 100% bonus depreciation. A study does not make the entire building eligible for immediate expensing.
Hypothetical Phoenix retail-center example
Assume an individual foreign investor acquires and places a Phoenix retail center in service in 2026. Assume the acquisition-date requirements are satisfied. The study identifies eligible components equal to 30% of depreciable basis.
| Step | Calculation | Amount |
|---|---|---|
| Purchase price | Assumed price | $15,000,000 |
| Land allocation | Assumed supported allocation | ($3,000,000) |
| Depreciable basis | $15,000,000 − $3,000,000 | $12,000,000 |
| Eligible components | $12,000,000 × 30% | $3,600,000 |
| First-year component bonus deduction | $3,600,000 × 100% | $3,600,000 |
| Illustrative federal tax reduction | $3,600,000 × 37% | $1,332,000 |
This is a hypothetical allocation, not a study result or promised reclassification rate. Actual reclassification percentages depend on the property and supporting analysis.
The example assumes net-basis taxation and full current deductibility. It applies a hypothetical 37% federal marginal rate to the entire deduction. It excludes state and home-country taxes, study fees, and future recapture. It is not a refund estimate.
The calculation shows the tax effect of the component deduction, not incremental savings versus every alternative depreciation method. The remaining building depreciation is separate. IRS Publication 946 explains why land is not depreciable.
For a property held in an earlier year, ask your CPA whether an accounting-method change is needed. Our Form 3115 guide provides context; the correct filing path depends on the depreciation history.
How do treaties and ownership structure affect the benefit?
Treaties and ownership structure require separate analysis; neither creates a blanket exemption from U.S. real-property taxation.
The U.S. model treaty's Articles 6 and 23 illustrate source-country taxation of real-property income and separate double-tax relief. The model is not a binding bilateral treaty. It does not establish a particular investor's entitlement to credits, exemptions, or reduced rates.
Check the investor's actual treaty and home-country law. Do not assume U.S. depreciation produces an identical deduction abroad or an immediate increase in foreign tax credits.
What about branch profits tax?
Foreign corporations may face branch profits tax in addition to tax on effectively connected income. IRC §884 imposes a statutory 30% rate on the dividend equivalent amount, subject to applicable treaty relief.
That amount starts with effectively connected earnings and profits and includes U.S. net-equity adjustments. It is not simply taxable rental income or cash distributed abroad.
Depreciation for earnings-and-profits purposes follows separate rules, including applicable alternative-depreciation requirements under IRC §312(k). Do not assume a bonus deduction reduces branch profits tax by the same amount.
Are REITs and foreign pension funds automatically exempt?
REIT ownership does not automatically eliminate FIRPTA exposure. IRC §897(l) provides a separate exception for qualifying foreign pension funds and certain wholly owned entities, subject to requirements. It is not a general exemption for every foreign pension investor or REIT investment.
Estate: distinguish fair market value from depreciated basis
For a nonresident noncitizen, an executor generally must file Form 706-NA when U.S.-situated assets exceed $60,000 in fair market value at death. This is a filing threshold, not a universal tax bill on everything above that amount. The IRS estate-tax guidance also explains that treaties can affect treatment.
A cost segregation study allocates cost; it does not establish an estate's fair market value. Accumulated tax depreciation does not determine the estate valuation.
Qualifying inherited property generally receives a basis adjustment under IRC §1014, subject to exceptions. If heirs inherit foreign-corporation shares, distinguish share basis from the corporation's basis in its real estate. Do not assume a share-basis adjustment resets the property's depreciation history inside the corporation.
What happens to depreciation when the property sells?
Depreciation reduces adjusted income-tax basis and can create recapture when the property sells. Model these consequences separately from FIRPTA withholding.
Depreciation recapture can convert part of a sale gain into ordinary income. For a fully taxable sale of §1245 property, ordinary-income recapture generally equals the smaller of asset-level gain and depreciation allowed or allowable.
Section 1250 property follows different rules. Depreciation beyond straight line can trigger ordinary-income recapture. For individuals, unrecaptured §1250 gain can face a maximum 25% federal rate under IRC §1(h). That is different from ordinary-income recapture. Avoid applying one recapture rate to every asset or ownership structure. IRS Publication 544 explains these distinctions.
A §1031 exchange generally applies to qualifying real property held for business or investment, not ordinary personal property. Its real-property classification rules are separate from depreciation classifications. Buying replacement §1245 property does not, by itself, establish tax deferral.
What should foreign investors do before commissioning a study?
Confirm net-basis tax treatment and deduction usability before estimating the benefit from a cost segregation study.
- Identify the taxpayer. Document who owns the property for U.S. tax purposes.
- Confirm rental-tax treatment. Review existing ECI status and any required net-basis election.
- Check eligibility. Review acquisition timing, placed-in-service dates, and asset classifications.
- Model deduction use. Include applicable loss limits and home-country treatment.
- Plan the exit. Model adjusted basis, recapture, and FIRPTA withholding separately.
- Coordinate estate advice. Address ownership and succession without treating a study as an appraisal.
Cost segregation can bring deductions forward, but the usable benefit depends on the taxpayer and the investment. Treat annual deductions, sale withholding, and final tax as separate calculations.
