US Capital Gains on Mexico Property Sale: 2026 Guide
US capital gains tax when selling Mexico property, Form 8949, foreign tax credit, Mexico ISR coordination, basis, depreciation recapture. Verify with CPA.
By Mexico Invest Editorial · Updated June 7, 2026 · 16 min read
Quick answer: US citizens and residents generally owe US capital gains tax on Mexico property sales in addition to Mexico ISR, report on Form 8949/Schedule D, convert amounts to USD, and may claim foreign tax credits (Form 1116) for Mexico tax paid. Depreciation recapture applies if you rented and claimed US depreciation. 1031 exchanges do not apply to foreign property. Verify all figures with a cross-border CPA, this guide is educational, not tax advice.
You can negotiate Playa occupancy and HOA perfectly and still lose on exit because US reporting, Mexico ISR withholding, and basis documentation were never modeled together. Mexico taxes the sale at closing through the notario; the IRS taxes worldwide gain on your US return. The two calculations use different rules, different basis stacks, and different forms.

Two-country tax event on every sale
Selling Mexico real estate triggers parallel tax systems, Mexico ISR on the disposition administered through the notario, and US capital gains reporting for US persons on worldwide income. Neither replaces the other. Mexico withholding at closing is typically not the final US tax, and US filing obligations exist even when Mexico exempts partial gain for qualifying primary residences under Mexican rules most vacation owners do not meet.
| Jurisdiction | Typical trigger | Who calculates |
|---|---|---|
| Mexico ISR | Notarized sale / fideicomiso assignment | Notario at closing |
| US capital gains | Calendar-year sale reporting | Taxpayer + CPA |
| Foreign tax credit | Mexico tax paid | Form 1116, CPA |
| Depreciation recapture | Prior Schedule E depreciation | US return, CPA |
Disclaimer: Tax law changes. Numbers here are illustrative frameworks. Retain a cross-border CPA before listing, not after accepting an offer.
US reporting mechanics (overview)
US persons report capital gain or loss from Mexico property on Form 8949 and Schedule D attached to Form 1040. Proceeds and basis are generally stated in USD using Treasury exchange rates or consistent methodology your CPA selects. Holding period determines short-term vs long-term rates, long-term often applies after more than one year but verify current IRS thresholds annually.
What counts as proceeds
Sale price per closing documents, typically the escritura value at notarized transfer, not informal side arrangements. Reduce by certain selling expenses per US rules (commissions, legal fees deductible per IRS guidance). Your CPA maps Mexican closing statements to US line items.
What counts as adjusted basis
US adjusted basis generally starts with documented purchase price plus buyer closing costs capitalized per US rules, plus improvements, minus depreciation taken on US returns if property was rented. US basis and Mexico ISR basis may differ because Mexico requires CFDI documentation and applies Mexican inflation adjustments under its rules, do not assume one number serves both countries.
Purchase discipline: Cost of Buying Property in Mexico.
Mexico ISR interaction (not US tax advice)
Mexico taxes gain on property dispositions through ISR, with withholding commonly applied at closing before net proceeds wire abroad. The notario calculates taxable gain from documented acquisition and improvement costs under Mexican rules, undocumented cash payments inflate ISR. Partial primary-residence exemptions exist under strict tests many foreign vacation owners fail.
Indicative ISR framework (illustrative only):
| Step | Example USD | Note |
|---|---|---|
| Sale price | $420,000 | Escritura value |
| Less documented acquisition | $350,000 | CFDI critical |
| Less documented improvements | $25,000 | Receipts + CFDI |
| Taxable gain (simplified) | $45,000 | Notario applies full rules |
| ISR withholding | Variable | 25% gross method or 35% net, notario calculates |

Foreign tax credit coordination
US persons may reduce US tax on Mexico-source gain by claiming foreign tax credits for Mexico ISR paid, reported on Form 1116. Credits are limited by US sourcing rules, separate category baskets, and cannot always offset net investment income tax or state taxes. Excess credits may carry forward or back per IRS rules, outcomes vary by total foreign income, other credits, and AMT exposure.
| Concept | Practical note |
|---|---|
| Credit vs deduction | Credit usually preferred, CPA decides |
| Withholding vs actual ISR | Reconciliation may be required in Mexico |
| Timing | US reporting year of sale, coordinate FX |
| State taxes | California et al. may tax gain separately |
| NIIT | 3.8% may apply, credits may not fully offset |
Planning mistake: Assuming Mexico ISR withholding equals US liability. Run dual projections before pricing the listing.
Depreciation recapture if you rented
Many Mexico investors rented through Airbnb or long-term leases and claimed US depreciation on Schedule E, typically 27.5-year residential rental depreciation on building value excluding land. On sale, US rules recapture depreciation at up to 25% ordinary rates (unrecaptured Section 1250 gain) in addition to capital gain on appreciation. Mexico ISR calculation does not eliminate US recapture.
| Scenario element | US impact |
|---|---|
| Years of Schedule E depreciation | Increases recapture amount |
| Land vs building split | Depreciation only on building portion |
| Sale after long hold | Still recapture, not forgiven |
| Mexico ISR paid | May credit partially, CPA models |
Rental history guide: US Taxes Mexico Rental Property. If you never rented, recapture is usually not an issue, basis is purchase plus improvements minus nothing.
Exchange rate and currency issues
Mexico transactions occur in pesos or USD depending on contract; escritura may be peso-denominated. US reporting requires consistent USD conversion, often Treasury year-end or spot rates on transaction dates per IRS guidance. Maintain records showing peso amounts, dates, and rates used. Large FX moves between purchase and sale years affect both perceived gain and credit calculations.
Record retention: Keep bank wire confirmations, notario statements, and CPA worksheets seven years minimum, longer if depreciation was claimed.
Fideicomiso sale and US reporting
Foreigners typically sell beneficial rights in a fideicomiso rather than fee simple title. US reporting still treats the disposition as a sale of the underlying real property interest for most taxpayers, the trust wrapper does not defer US gain. Trust bank fees and assignment costs may affect net proceeds and US selling expenses per CPA guidance.

1031 exchange does not apply
Section 1031 like-kind exchanges defer US gain when swapping qualifying US real property for other US real property. Foreign real property is not qualifying relinquished property for exchanging into US assets under standard 1031 rules. Competitors sometimes omit this, US sellers cannot rely on 1031 to defer Mexico condo gain by buying a US replacement rental. Plan liquidity for both ISR withholding and US tax due dates.
State tax layer (often forgotten)
US federal treatment is only one layer. Residents of California, New York, and other states with capital gains taxation may owe state tax on Mexico property sales without a foreign tax credit mirror of the federal Form 1116. Snowbirds maintaining US state residency remain subject to home-state rules, confirm with CPA before assuming Mexico sale is “offshore.”
Timeline: from listing to US filing
Typical sequence spans Mexico closing in one calendar year and US reporting the following April (or extension). POA remote sales add weeks but not different tax treatment.
| Phase | Action | Tax relevance |
|---|---|---|
| Pre-list | Model ISR + US gain with CPA | Price realistically |
| Under contract | Gather CFDI basis file | Withholding estimate |
| Closing | Notario withholds ISR | Credit documentation |
| Post-close | Wire net proceeds | FBAR if MX accounts high |
| Next year | US return + Form 1116 | Pay or refund difference |
Documentation checklist for US reporting
- Original purchase escritura and trust deed
- All buyer closing CFDI: ISAI, notario, fideicomiso setup
- Improvement invoices with CFDI and permits where applicable
- Depreciation worksheets if rented (Form 4562 history)
- Sale closing statement and ISR withholding certificate
- Exchange rates documented for every conversion
- AMPI commission invoices if capitalized or deducted per CPA
- HOA clearance and predial receipts (Mexico side)
Missing documents hurt Mexico ISR first, then US basis when you cannot prove purchase price.
Worked example (illustrative dual-country: not advice)
Facts: US citizen bought Quintana Roo condo $350,000 all-in documented 2022, rented 2023–2025 claiming $28,000 cumulative US depreciation, sells $420,000 escritura 2026, Mexico ISR withheld $18,000 indicative, US long-term gain before credits $55,000 indicative including recapture component.
| Line | Indicative USD |
|---|---|
| Sale proceeds | $420,000 |
| US adjusted basis (after depreciation) | ~$365,000 |
| US taxable gain (simplified) | ~$55,000 |
| Mexico ISR withheld | ~$18,000 |
| US federal tax before credits | CPA calculates |
| Foreign tax credit | Up to ISR paid, limits apply |
| Net US tax due | CPA required |
Numbers vary wildly with exemption eligibility, documentation gaps, state residency, and NIIT. Do not use this table for filing.
Common mistakes US sellers make
Assuming notario handles US taxes. Notarios administer Mexican law. US Form 8949 is your obligation.
No CFDI at purchase. Saves pennies at closing; costs five figures at ISR and complicates US basis proof.
Ignoring depreciation recapture. Surprise ordinary-rate US tax on top of capital gain rate expectations.
1031 planning that cannot execute. Foreign property exclusion kills most exchange strategies.
Single-country CPA. Mexico specialist without US Form 1116 experience (or vice versa) misses half the problem.
Wrong year FX. Inconsistent conversion methodology triggers audit friction.
Who should be on your exit team
| Role | Function |
|---|---|
| Mexican real estate attorney | POA, contract, DD, closing coordination |
| Notario | Deed, ISR withholding, registry |
| Mexican tax counsel | ISR exemption tests, reconciliation |
| US cross-border CPA | Form 8949, 1116, recapture, state |
| US estate attorney | If trust or entity holds property |

Planning before you buy (exit starts at entry)
US capital gains pain is proportional to undocumented basis and depreciation choices made years earlier. At purchase: capitalize closing correctly, store CFDI digitally, track improvements, and decide rent-vs-personal-use strategy with CPA input before first Schedule E filing.

Remote sale: same US rules
Selling via Mexican consulate POA from Texas or California does not change US reporting. ISR withholding still applies at notario. Timeline runs 6–10 weeks POA to wire, plan US estimated payments if sale falls late in tax year.

Entity ownership complications
If property sits in a Mexican corporation or US LLC owning Mexican interests, US reporting may involve Form 5471, PFIC considerations, or GILTI, far beyond individual Schedule D. Entity sellers must retain international tax counsel before listing; this guide assumes individual fideicomiso ownership typical of condo investors.
Bottom line
US capital gains on Mexico property sales are reportable on your US return with USD basis and proceeds, foreign tax credits for Mexico ISR paid subject to limits, and depreciation recapture if you rented. Mexico ISR at closing is parallel, not substitutive. 1031 does not apply. Model both countries before listing, document CFDI from day one, and verify every projection with a cross-border CPA, not a notario, not an AMPI broker, not an internet article.

Frequently Asked Questions
Generally yes. US persons must report worldwide capital gains on US tax returns regardless of where property is located. Mexico ISR withheld at closing does not eliminate US reporting — foreign tax credits may reduce double taxation subject to US rules and limits. Consult a cross-border CPA.
Typically sale proceeds minus adjusted basis in USD, minus selling expenses, with adjustments for depreciation recapture if the property was rented. Basis includes documented purchase price and closing costs converted at appropriate exchange rates. US rules differ from Mexico ISR calculation — model both.
Often partially. Mexico ISR paid on the sale may qualify for foreign tax credit on Form 1116, subject to basket limitations and US sourcing rules. Credits do not automatically equal ISR withheld — reconciliation filings may apply. CPA required for your facts.
Not necessarily. US long-term capital gains rates and net investment income tax may produce US liability exceeding credits, or credits may exceed US tax depending on basis, holding period, and depreciation history. Withholding is not final tax in either country.
If you rented the Mexico condo and claimed US depreciation on Schedule E, selling triggers depreciation recapture taxed at higher ordinary rates up to 25% on the US side — separate from Mexico ISR mechanics. Unrecaptured Section 1250 rules apply to US persons; verify with CPA.
No. Like-kind exchanges under IRC Section 1031 generally do not apply to foreign real property. You cannot defer US gain by exchanging into US property or vice versa using 1031 for the Mexico leg. Plan exit tax before purchase if relevant.
Purchase escritura and CFDI, all improvement invoices, closing statements, depreciation schedules if rented, Mexico ISR withholding certificate from notario, USD conversion documentation, and sale closing statement. Missing basis documentation hurts both Mexico ISR and US gain calculations.
Both roles differ. The notario calculates Mexico ISR withholding at closing. A US CPA reports US Form 8949/Schedule D and Form 1116 foreign tax credits. Use a cross-border specialist who coordinates both — notario advice is not US tax advice.
