Capital gains tax on foreign property: US reporting, exclusions, and how to reduce tax

US citizens and resident aliens generally report worldwide capital gains on a US tax return, including a foreign home or rental sold in 2025 and filed in 2026. The main ways to reduce the US capital gains tax on a foreign property sale are the Section 121 home sale exclusion, foreign tax credits, and accurate basis adjustments. The IRS confirms that US citizens and resident aliens abroad are generally taxed under the same worldwide-income rules that apply in the United States.

The following 3 tax levers usually matter most before you file:

• Section 121 exclusion: up to $250,000 of gain for single filers or $500,000 for certain married joint filers on a qualifying main home.
• Foreign tax credit: a credit may offset US tax when the foreign country taxes the same gain.
• Adjusted basis: purchase costs, capital improvements, selling costs, depreciation, and exchange rates can change the taxable gain.

US expats should treat capital gains tax (CGT) on foreign real estate as a filing project, not just a sale calculation. A house sale may touch Form 8949, Schedule D, Form 1116, Form 4797, Form 8938, FBAR, or Form 3520, depending on ownership, rental history, foreign accounts, and inheritance facts.

2026 update note: This guide is built for a 2025 tax-year sale filed in 2026. Use 2025 long-term capital gains brackets for a 2025 sale, but verify year-sensitive items before filing, including capital gains rate thresholds, Section 121 eligibility, foreign exchange-rate records, and any 2026 IRS updates that affect your return. IRS 2026 inflation guidance updates the 2026 long-term capital gains income thresholds, but those thresholds apply to property sold in 2026, not a 2025 sale.

How capital gains are reported on your tax return

A foreign property sale is usually reported in US dollars on Form 8949 and Schedule D for the 2025 Form 1040, with supporting forms added when rental depreciation, foreign tax, foreign accounts, or entity ownership apply. Form 8949 reconciles sale details, and Schedule D summarizes capital gains and losses.

The following 3 reporting steps cover most foreign property sale tax in the US:

1. Convert the sale into US dollars. Use reliable exchange rates for the purchase date, improvement dates, depreciation records, selling costs, and sale date.
2. Calculate gain or loss. Subtract adjusted basis from amount realized, then classify the gain as short-term or long-term.
3. Attach the correct forms. Use Form 8949 and Schedule D for capital assets, and add other forms when the property was rented, inherited, held through an entity, or taxed abroad.

A fully excludable main-home sale may not always need to be reported. IRS Publication 523 says a home sale generally is not reported if there is no taxable gain, no Form 1099-S, and the taxpayer does not choose to report it.

The reporting path depends on property use, but most 2025 foreign property sales start with Form 8949 and Schedule D.

 

You can review TFX’s capital gains guidance for expats for broader rules on US rates, losses, and expat filing issues.

How to report the sale of foreign property

Report selling foreign property for US tax purposes by converting each relevant amount into US dollars, calculating gain or loss, and filing the forms that match the property type. Most personal or investment sales use Form 8949 and Schedule D, while rental property may also require Form 4797.

The following 4 documents usually support a foreign real estate sale filing:

• Final purchase contract or inheritance valuation.
• Closing statement showing sale proceeds and costs.
• Receipts for capital improvements and major repairs.
• Foreign tax assessment, withholding certificate, or payment proof.

Direct foreign real estate generally is not an FBAR asset, but the foreign bank account receiving sale proceeds may trigger FBAR reporting if aggregate foreign financial accounts exceed $10,000 at any time during the year. IRS guidance states that FBAR is filed electronically with FinCEN and is due April 15, with an automatic extension to October 15.

Use TFX’s Form 1040 guide for expats if you need to see where sales forms connect to the individual return.

Capital gains tax forms checklist for foreign property sales

A 2025 foreign property sale may require 2 core forms – Form 8949 and Schedule D – plus extra forms if you paid foreign tax, rented the property, inherited it, or moved funds through reportable foreign accounts. The right checklist depends on use, ownership, and thresholds.

The following 8 filing items should be checked before reporting the sale:

• Form 8949: reports sale proceeds, adjusted basis, gain or loss, and short-term or long-term classification.
• Schedule D: summarizes capital gains and losses from Form 8949.
• Form 4797: may apply to rental or business property sales and depreciation-related gain.
• Form 1116: may apply when foreign capital gains tax was paid or accrued.
• Form 8938: may apply if specified foreign financial assets exceed FATCA thresholds.
• FBAR: may apply if sale proceeds touched foreign accounts and aggregate foreign account balances exceeded $10,000.
• Form 3520: may apply when inherited foreign property or related foreign gifts exceed reporting thresholds.
• Form 8833: may apply if you take a treaty-based return position.

The form decision usually starts with the property type: main home, rental property, inherited property, or entity-owned property.

A foreign property sale can create a filing chain, which is why you should let us handle the US filing work.

How to calculate your capital gains tax on overseas property

To calculate capital gains tax on overseas property, subtract adjusted basis from amount realized, then apply the correct 2025 tax rate, exclusion, credit, and depreciation rules. The IRS describes capital gain or loss as the difference between adjusted basis and the amount realized on sale.

Formula: Amount realized – adjusted basis = capital gain or loss

Adjusted basis usually starts with the purchase price and increases for qualifying capital improvements. It generally decreases for depreciation allowed or allowable during rental or business use.

Based on our client scenario at TFX: a US expat bought a foreign home for the USD equivalent of $320,000, paid $18,000 of purchase costs, added $42,000 of capital improvements, and later sold it for $510,000 after $20,000 of selling costs. The adjusted basis is $380,000, the amount realized is $490,000, and the starting gain is $110,000 before any exclusion, credit, or depreciation adjustment.

Basis changes are often the difference between a taxable gain and a fully offset 2025 sale.

 

See TFX’s guide to buying foreign real estate for records to keep from the purchase date, and review currency-risk considerations for Americans abroad if exchange-rate swings changed the USD result.

When to use exchange rates

Foreign property sale calculations must be reported in US dollars, and each transaction should use an exchange rate tied to the correct date or period. The IRS says foreign-currency amounts generally must be translated into US dollars using a rate that properly reflects income.

The following 4 conversion points are the ones most likely to affect CGT:

• Purchase price and purchase closing costs.
• Capital improvements paid in foreign currency.
• Depreciation and rental income records.
• Sale proceeds, selling costs, and foreign tax paid.

Use the exchange rate connected to each transaction date, because one blended rate can distort a 2025 gain.

 

Based on our client scenario at TFX: a property bought for €300,000 when €1 equaled $1.10 created a $330,000 USD purchase basis. If it sold for €300,000 when €1 equaled $1.25, the USD sale amount is $375,000 before costs, even though the euro price did not change.

 

 

For broader investment issues, see TFX’s guide to foreign investing tax implications.

Short-term vs long-term capital gains for selling foreign property

Property held 1 year or less is generally short-term, while property held more than 1 year is generally long-term. Short-term gain is usually taxed at ordinary income rates, while long-term gain may qualify for 0%, 15%, or 20% rates in 2025.

A sale date that moves ownership from 365 days to more than 1 year can change the US rate category.

 

Based on our client scenario at TFX: a taxpayer who sells a foreign apartment after 11 months may have the gain taxed as short-term ordinary income. Waiting until the property has been held for more than 1 year, when commercially feasible, can move the same gain into long-term capital gain treatment.

You can compare related rules in TFX’s guide to capital gains and losses for US taxpayers.

How to reduce or eliminate US tax on foreign property sales

Exclusions, credits, timing, ownership structure, and basis documentation can reduce or eliminate US tax on the sale of foreign property, but no single tactic works for every 2025 sale. The best answer depends on whether the property was a main home, rental, inherited asset, or entity-owned asset.

The following 5 strategies explain how to avoid capital gains tax on foreign property where the law allows it, or reduce the tax when full elimination is not available:

• Use the Section 121 exclusion for a qualifying principal residence.
• Claim a foreign tax credit for eligible foreign capital gains tax.
• Track basis, improvements, depreciation, and selling costs carefully.
• Time the sale for long-term capital gain treatment, where possible.
• Review the ownership structure before signing a sale contract.

The lowest-risk strategies usually involve documentation and statutory exclusions, not last-minute entity transfers.

 

The Foreign Earned Income Exclusion does not exclude real estate capital gains. TFX explains the income exclusion separately in its foreign earned income exclusion guide.

Exclude gains on your principal residence (Section 121)

Section 121 can exclude up to $250,000 of gain for a single filer or $500,000 for certain married joint filers when the foreign property was the taxpayer’s principal residence. The taxpayer generally must meet ownership and use tests during the 5-year period before sale.

The following 2 tests usually decide Section 121 eligibility:

• Ownership test: You owned the home for at least 2 years during the 5-year period ending on the sale date.
• Use test: You used the home as your main home for at least 2 years during that same 5-year period.

Section 121 can reduce a qualifying 2025 foreign main-home gain by up to $250,000 or $500,000.

 

Based on our client scenario at TFX: a married couple sold their foreign main home in 2025 for a $420,000 gain after living there for 30 months during the 5-year lookback period. If they meet the joint-return rules, the $500,000 exclusion can reduce the taxable gain to $0 before considering foreign tax credits.

 

 

For a deeper residence-focused discussion, see TFX’s foreign and US primary residence capital gains guide.

Can I use the home sale exclusion if the home is overseas?

Yes, a foreign home can qualify for the Section 121 home sale exclusion if it meets the same ownership and use tests as a US home. The location outside the United States does not disqualify the home, but the 5-year lookback and prior-exclusion rules still apply.

The following 3 proof items help support a foreign principal residence claim:

• Local registration, utility bills, or residence permits showing the home was your main residence.
• Travel records showing days in and out of the country.
• Sale, purchase, and occupancy records tied to the 5-year lookback period.

Based on our client scenario at TFX: a US citizen sold a home in Portugal on August 1, 2025 after living there from September 2021 through December 2023. That timeline can meet the 2-year use test because the qualifying months fall inside the 5-year period ending on the sale date.

A caution is needed for older occupancy periods. Time lived in a home during 2020 may fall outside the lookback period for many 2026 sales, so do not assume the exclusion applies just because the home was once your main home.

Leverage the foreign tax credit for foreign capital gains tax

Foreign capital gains tax may offset US tax when the tax is creditable, paid, or accrued to a foreign country, and assigned to the correct income category on Form 1116. The foreign tax credit is limited and may not fully eliminate US tax on every 2025 sale.

The following 3 checks help decide whether Form 1116 is needed:

• You paid or accrued foreign income tax on the property gain.
• The same gain is included on your US return.
• The tax is not refunded, subsidized, or treated as a noncreditable local charge.

 

 

Foreign tax paid can reduce US tax only within the foreign tax credit rules and limits.

 

Read TFX’s foreign tax credit guide and foreign tax credit carryover guide for examples of how the credit can reduce double taxation.

Use a like-kind exchange only when the property qualifies

A Section 1031 like-kind exchange is generally limited to qualifying real property held for investment or business use, not a personal home. IRS Publication 544 also states that US real property and foreign real property are not like-kind to each other.

The following 3 requirements should be reviewed before relying on Section 1031:

• The relinquished and replacement properties are qualifying real property.
• The property is held for investment or business use, not personal use.
• The exchange satisfies strict timing, identification, and qualified-intermediary rules.

A foreign-to-foreign exchange may be possible only when all Section 1031 requirements are met. A US-to-foreign or foreign-to-US exchange generally fails the like-kind requirement because the IRS treats US and foreign real property as not like-kind to each other.

See TFX’s guide to like-kind exchanges of rental property under Section 1031 before a sale contract is signed.

2025–2026 long-term capital gains rates by year of sale

Use the long-term capital gains rate for the year you sold the property, not the year you bought it or filed the return. A foreign property sold in 2025 and filed in 2026 generally uses 2025 long-term capital gains brackets.

For a 2025 sale filed in 2026, use the 2025 taxable-income thresholds shown below.

 

The 3.8% Net Investment Income Tax may also apply when modified adjusted gross income exceeds $200,000 for single or head-of-household filers, $250,000 for married filing jointly, or $125,000 for married filing separately. Foreign tax credits cannot be used to reduce NIIT liability.

For property sold in 2026, use 2026 thresholds, not the 2025 thresholds above.

Take advantage of tax treaties without assuming a full exemption

Tax treaties may affect how a foreign property gain is taxed, but they do not automatically eliminate US tax for US citizens or residents. Many treaties preserve source-country taxation of real estate and include saving clauses that allow the United States to tax its citizens.

The following 4 treaty items should be checked before claiming treaty relief:

• Treaty residence article.
• Real property or capital gains article.
• Saving clause and exceptions.
• Whether Form 8833 disclosure is required.

Form 8833 is used to disclose certain treaty-based return positions under Internal Revenue Code section 6114 or dual-resident positions under Treasury regulations. States may also tax differently because some states do not honor federal treaty positions.

For country-specific research, start with TFX’s US tax treaties guide and then confirm the specific treaty text.

Rely on a trust or other legal entity only after modeling the reporting burden

A trust, corporation, partnership, or other legal entity can change ownership and reporting outcomes, but it usually does not make US tax disappear. Foreign trusts, companies, and partnerships can add forms, penalties, local-law issues, and higher preparation costs to a 2025 sale.

Entity ownership can change the forms required before it changes the tax result.

 

Coordinate entity choice with US and local-country professionals before transferring property. TFX’s guide to property ownership structures for US expats and foreign grantor trusts explains common reporting traps.

Other tax reduction strategies before you sell

Other tax reduction strategies focus on timing, basis, documentation, and ownership details that can reduce a taxable 2025 gain without relying on aggressive positions. These steps are especially useful when Section 121 does not apply or when a foreign tax credit will be limited.

The following 6 actions should be completed before a sale closes:

• Gather purchase and sale contracts.
• Add eligible capital improvements to the basis.
• Separate repairs from improvements.
• Track depreciation allowed or allowable.
• Estimate foreign tax before choosing a closing date.
• Model the sale under both local and US rules.

Capital losses may offset capital gains, but losses from personal-use property generally are not deductible. IRS guidance allows capital losses to offset capital gains and permits limited net capital loss deductions, but personal-use losses are treated differently.

See TFX’s guide to deductible expenses for property investments and year-end filing strategies before closing a high-gain sale.

Special situations and property types

Foreign property tax results change because a main home, rental property, inherited home, and vacation property use different rules for basis, depreciation, loss deductibility, and exclusions. The same $100,000 economic gain can produce very different US tax outcomes depending on property type.

The following 4 scenarios are the most common decision points in foreign property sales:

• Principal residence – check Section 121.
• Rental or business property – check depreciation and Form 4797.
• Inherited property – check date-of-death basis and Form 3520.
• Vacation home – check personal-use rules and loss limits.

An inherited foreign property may also raise separate foreign inheritance reporting issues. TFX’s foreign inheritance tax guide explains reporting points beyond the later sale.

Foreign property sale example: primary residence vs rental vs inherited home

A primary residence, rental, and inherited home can have the same $500,000 sale price but different US tax results because basis, exclusions, depreciation, and forms change by property type. This is where us capital gains tax on foreign property sale calculations often diverge sharply.

Property type determines the starting basis, available exclusion, depreciation impact, and forms used.

 

Based on our client scenario at TFX: three US taxpayers sold foreign homes for $500,000. The main-home seller used Section 121, the rental owner had a depreciation-related gain, and the inheritor used a date-of-death valuation that reduced taxable gain.

What is Section 1250 property?

Section 1250 property generally means depreciable real property, such as a rental building, but not land. For foreign rental real estate, Section 1250 matters because prior depreciation can affect how part of the sale gain is taxed.

Section 1250 is about depreciable real property, while unrecaptured Section 1250 gain is a tax-rate category for certain depreciation-related gain.

 

Read TFX’s foreign rental income tax guide if the property was rented before the sale.

How depreciation recapture works

Depreciation claimed or allowable on foreign rental or business property reduces basis and can increase taxable gain when the property is sold. For real property, the depreciation-related portion is often handled as unrecaptured Section 1250 gain taxed at up to 25%, not always ordinary recapture.

Based on our client scenario at TFX: a foreign rental building had a $300,000 original building basis and $50,000 of accumulated depreciation. The adjusted basis became $250,000; if the building sold for $380,000 after costs, the total gain was $130,000, including a depreciation-related component.

A rental sale can create both regular long-term gain and depreciation-related gain.

 

Keep depreciation schedules even if a prior preparer made errors. Depreciation “allowed or allowable” can affect the sale calculation, so missing records can increase audit risk and preparation time.

Selling inherited foreign property

Inherited foreign property usually receives a basis tied to fair market value at the date of death, rather than the original purchase price paid by the decedent. A later sale generally measures gain from that inherited basis, and Form 3520 may apply above the $100,000 threshold.

The following 4 records should be kept for an inherited foreign property sale:

• Probate or estate documents.
• Date-of-death valuation.
• Sale contract and closing statement.
• Foreign tax or inheritance documents.

Inherited basis can materially reduce US gain when the property appreciated before death.

 

See TFX’s guide to reducing capital gains tax on inherited property for deeper basis and documentation examples.

Vacation homes and second properties

Vacation homes and second properties are treated differently from a main home or rental property because Section 121 may not apply, and personal-use losses are generally not deductible. If the property was rented, mixed-use rules and depreciation can also affect the 2025 sale.

The following 3 distinctions matter most for a vacation home:

• Adjusted basis can include purchase costs and capital improvements; selling costs generally reduce the amount realized.
• Personal-use losses generally are not deductible.
• Section 121 applies only if the property qualifies as a principal residence.

Based on our client scenario at TFX: a US expat sold a beach apartment used for 6 weeks a year and never rented it. The gain may be taxable, but a personal-use loss would generally not be deductible.

Rental property and investment real estate

Rental and investment real estate often creates both capital gain and depreciation-related gain when sold. During ownership, rental income and expenses generally flow through Schedule E, and depreciation records become part of the sale calculation later.

Rental expenses affect the sale differently depending on whether they are current deductions or capitalized improvements.

 

TFX’s rental properties and US tax return guide explain how rental income, expenses, and depreciation connect before a sale.

While owned

Recordkeeping during ownership can reduce filing errors when the foreign property is sold years later. Keep at least 5 categories of records: purchase documents, improvement receipts, rental income and expenses, depreciation schedules, and exchange-rate support.

The following 5 records should be organized before listing a rental or investment property:

• Purchase contract and closing statement.
• Capital improvement invoices.
• Annual rental income and expense records.
• Depreciation schedules.
• Foreign tax and exchange-rate records.

IRS Publication 527 explains rental income, expenses, and depreciation reporting; IRS Publication 551 explains that basis records should be kept to support gain or loss calculations.

Use TFX’s tax and financial records retention guide and ultimate tax documents checklist to organize documents before the closing year.

When selling

The selling-year checklist should start when an offer is accepted, not when the 2025 return is prepared. Closing statements, foreign withholding slips, exchange-rate records, and payment evidence often determine whether foreign credits, basis adjustments, and reporting forms are correct.

The following 6 steps should be completed between offer acceptance and return filing:

• Request a draft closing statement before settlement.
• Confirm whether local withholding applies.
• Collect proof of foreign tax paid or accrued.
• Convert sale proceeds and selling costs into USD.
• Update depreciation records through the sale date.
• Confirm whether the sale proceeds triggered FBAR or FATCA reporting.

Foreign withholding is not automatically equal to the final US tax due. It may be a creditable foreign income tax, a local transfer tax, or a prepayment that must be reconciled under the foreign country’s rules.

If the sale involves US real property withholding concepts for a foreign person, TFX’s Form 8288 guide covers that separate FIRPTA context.

Conclusion

Foreign property sales can create US tax even when the property, buyer, closing agent, and bank account are all outside the United States. For a 2025 sale filed in 2026, the core tasks are calculating USD gain, checking exclusions, and filing the correct forms.

The following 5 next steps help reduce errors before filing:

• Confirm whether the property was personal, rental, inherited, or entity-owned.
• Convert purchase, improvement, depreciation, sale, and tax payments into USD.
• Check Section 121 before reporting a principal residence sale.
• Match foreign tax paid to Form 1116 credit rules.
• Review FBAR, FATCA, Form 3520, and treaty disclosure triggers.
