Americans in Mexico tax guide 2026: US filing and Mexico taxes

Americans living in Mexico generally still file a US federal tax return because US citizens and resident aliens are taxed on worldwide income even while abroad. For the 2025 tax year filed in 2026, Mexico may also tax you based on Mexican residence or Mexico-source income, while the Foreign Earned Income Exclusion, Foreign Tax Credit, and the US–Mexico treaty can reduce double taxation.

The US and Mexican systems use different residence, income-source, filing, and reporting rules. Americans planning a move should review our guide to moving to Mexico from the US, while dual-residence and cross-border income cases may also require the US–Mexico tax treaty rules.

The following 6 topics cover the main decisions for Americans filing from Mexico in 2026:

• US filing deadlines and forms for the 2025 tax year.
• Mexican tax residence and Mexico-source income.
• Mexican income tax and IVA rules relevant in 2026.
• FEIE versus Foreign Tax Credit treatment.
• FBAR and Form 8938 foreign-account reporting.
• Treaty, pension, property, inheritance, and fideicomiso issues.

The IRS’s filing guidance for US citizens and resident aliens abroad confirms that living overseas does not by itself end US filing obligations. Taxpayers who qualify under IRC Section 911 can use the Foreign Earned Income Exclusion rules, subject to the applicable tests and limits.

Quick answers

For the 2025 US tax year filed in 2026, Americans in Mexico can face obligations in both countries, but filing in 2 systems does not automatically mean paying tax twice. The answer depends on citizenship or green-card status, Mexican residence, where work is performed, foreign accounts, and whether Form 2555 or Form 1116 applies.

Do Americans in Mexico still file US taxes? Yes. US citizens and resident aliens generally report worldwide income on Form 1040 when they meet the applicable filing threshold, even if they live in Mexico.

When can Mexico tax your income? Mexican residents may fall within Mexico’s resident income-tax system, while nonresidents can owe Mexican tax on specified Mexico-source income.

Can you use FEIE and FTC together? They can both appear on one return in appropriate circumstances, but you cannot claim a Foreign Tax Credit for Mexican tax allocable to income excluded under FEIE.

Are FBAR and FATCA the same filing? No. The TFX comparison of FBAR and Form 8938 explains the different forms, while the IRS comparison of Form 8938 and FBAR requirements sets out their separate thresholds and filing methods.

Do employees and contractors follow the same US rules? No. Employees commonly report wages, while self-employed taxpayers may also need Schedule C and Schedule SE.

Does living in Mexico stop US worldwide-income reporting? No. Our US expat tax guide explains why citizenship- and residence-based rules can operate at the same time.

US vs Mexico deadlines

For a 2025 calendar-year US return, the regular federal deadline was April 15, 2026, while qualifying taxpayers abroad received an automatic filing extension to June 15, 2026. Mexico’s 2025 annual individual income tax declaration was filed during April 2026, although a taxpayer’s Mexican filing requirement depends on income type and status.

The key distinction is that a US filing extension does not move the April 15, 2026 payment date for 2025 federal income tax, while Mexico’s 2025 individual annual return window ran through April 2026.

 

The IRS explains the current filing methods on its individual filing page. For cross-border timing, TFX also covers foreign-country tax filing deadlines and the rules for requesting a US tax extension from abroad.

If you only remember one thing: an extension to file your US return is not automatically an extension to pay your 2025 federal tax.

 

What to file in the US

A Mexico-based American may need 8 or more US forms or schedules depending on income, foreign taxes, accounts, and business interests. Form 1040 is the core individual return, while Form 2555, Form 1116, FinCEN Form 114, Form 8938, Schedule C, and Schedule SE address distinct international or self-employment issues.

Most employees start with Form 1040 plus Form 2555 or Form 1116, while contractors commonly add Schedule C and Schedule SE, and foreign-account holders may also need FBAR or Form 8938.

 

The following 3 combinations cover common Mexico-based profiles:

• Employee: Form 1040 plus Form 2555 or Form 1116, with FBAR/Form 8938 when account or asset thresholds are met.
• Independent contractor: Form 1040, Schedule C, Schedule SE, and potentially Form 2555 or Form 1116.
• Foreign-account holder: Form 1040 plus any applicable income forms, with FinCEN Form 114 and possibly Form 8938.

If reviewing these requirements reveals that you also missed US returns or foreign-account reporting in earlier years, see the catch-up options offered by TFX.

TFX’s expat IRS tax form checklist covers common international forms in more detail. Contractors can also use the IRS Self-Employed Individuals Tax Center to confirm federal self-employment requirements.

Checklist: Documents to gather

For a 2025 US return filed in 2026, organize records into 5 groups: US income, Mexican income and taxes, financial accounts, residence and housing evidence, and treaty support. The right documentation matters because Form 2555, Form 1116, FBAR, and Form 8938 rely on different dates, amounts, and proof.

The following 5 record groups cover most Mexico-based individual filings:

• US tax records: Forms W-2, 1099, prior-year return, estimated-tax payment records, and brokerage statements.
• Mexican records: CFDI payroll or professional-services records, Mexican income-tax payment evidence, SAT filings, and employer withholding records.
• Bank and investment records: year-end balances, maximum annual balances, account numbers, ownership details, and investment statements.
• Residence and housing evidence: passport travel dates, lease or property records, utility statements, and housing expenses relevant to Form 2555.
• Treaty support: documents establishing residence, income type, payer, source, and any position that depends on a treaty article.

For records supporting a Foreign Tax Credit, a Mexican assessment, payment receipt, or withholding certificate should identify the tax paid and the income to which it relates. Form 1116 instructions are available on the IRS Form 1116 page.

Keep tax records long enough to support the return and any later IRS inquiry; the appropriate period depends on the item and circumstances. TFX explains practical retention periods in its tax recordkeeping guide.

Mexico: tax overview

Mexico taxation in 2026 starts with residence and source: Article 9 of the Federal Fiscal Code looks first to a home in Mexico and, when a person also has a home elsewhere, to the center of vital interests. Mexico also applies a 16% standard IVA rate to covered transactions and progressive resident ISR rates.

Mexico tax system in 60 seconds

The Mexican taxation system separates residents from nonresidents and applies different rules to income tax, withholding, IVA, property transactions, and other items. SAT administers federal tax obligations, while local governments can impose taxes such as predial on real property.

Residence changes the starting point: a Mexican resident can face resident income-tax rules, while a nonresident is generally taxed under the rules for Mexican-source income.

 

A Mexican tax return is administered through SAT when the taxpayer has an annual filing obligation. For 2025 income, SAT directed individuals who were required to file an annual return to file during April 2026.

The Mexico tax system is separate from the IRS residence tests used for FEIE. A US citizen can be a Mexican tax resident and still need a US Form 1040, while the Foreign Tax Credit rules may reduce US income tax on income also taxed by Mexico.

Do you pay taxes in Mexico?

Yes, taxes in Mexico can apply to Americans who become Mexican tax residents or receive taxable Mexican-source income, even though they also remain within the US tax system. There are 3 common cases: Mexican residents, nonresidents with Mexican-source income, and Americans whose US filing obligation continues regardless of Mexican residence.

The following 3 cases cover the main starting points:

• Mexican resident: resident income-tax rules can apply based on Mexican domestic law.
• Nonresident with Mexican-source income: Mexico can tax specified income sourced to Mexico under the applicable nonresident provisions.
• US citizen or resident alien: US worldwide-income reporting can continue even when Mexico also taxes the same income.

Does Mexico have taxes? Yes. Federal taxes include income tax, known as ISR, and value-added tax, known as IVA; property-related and local taxes can also apply. Mexico itself is the taxing jurisdiction; individuals and businesses subject to Mexican law pay applicable taxes to federal, state, or municipal authorities.

Mexican individuals who fall within the applicable tax rules can owe ISR, IVA, or other taxes depending on income and transactions.

Does Mexico have income tax? Yes. Mexico imposes ISR, and the 2026 resident individual schedule ranges from 1.92% to 35%. For individuals, the applicable calculation depends on residence, income category, deductions, withholding, and other statutory rules.

You can if you are a tax resident there or earn income that Mexican law treats as Mexican-source.

Mexican tax residence is not the same as holding a temporary or permanent residence card. Immigration permission can be relevant evidence about your circumstances, but Article 9 of the Federal Fiscal Code uses its own tax-residence test.

Who qualifies as a Mexico tax resident?

Mexico tax residency is not determined by a blanket 183-day domestic rule. Under Article 9 of the Federal Fiscal Code, an individual who establishes a home in Mexico is a resident; if that person also has a home abroad, Mexico examines the center of vital interests, including a greater-than-50% Mexican-source-income test.

The following 3-part decision path reflects the domestic rule:

1. Do you have a home in Mexico? If no, other source-based Mexican tax rules may still apply; if yes, continue the residence analysis.
2. Do you also have a home in another country? If no, the Mexican home points to Mexican residence under Article 9; if yes, examine the center of vital interests.
3. Where is your center of vital interests? Mexico identifies this in circumstances including when more than 50% of total calendar-year income is Mexican-source or the principal center of professional activities is in Mexico.

The US–Mexico income tax treaty has a separate tie-breaker for a person treated as resident by both countries. Article 4 considers permanent home, center of vital interests, habitual abode, nationality, and, if needed, mutual agreement between the competent authorities.

Mexican domestic residence and the US FEIE residence tests answer different questions, so passing the 330-day US physical presence test does not determine Mexican residence.

 

TFX compares the US-side Bona Fide Residence Test and Physical Presence Test. Those tests should not be substituted for Mexico tax residency rules.

Based on our client scenario at TFX: a US employee who keeps a home in Texas and rents a long-term home in Mexico cannot decide Mexican residence from days alone. If more than 50% of total calendar-year income has a Mexican source, Article 9 identifies that as one circumstance placing the center of vital interests in Mexico.

Mexico tax rate: what people mean

A Mexico tax rate can refer to at least 4 different figures: a marginal ISR bracket, the effective rate on total income, payroll or other withholding, or IVA charged on a transaction. For 2026, resident individual ISR brackets run from 1.92% through 35%, while the standard IVA rate is 16%.

How much are taxes in Mexico? There is no single percentage. Your result depends on residence, income level, income category, deductions, withholding, and whether the amount being discussed is ISR, IVA, or another tax.

Income tax rate in Mexico refers to the applicable ISR computation rather than one flat personal rate. A resident’s top marginal bracket does not mean every peso of income is taxed at that rate.

The following 4 terms prevent common rate comparisons from being mixed together:

• Marginal rate: the percentage applied to the next portion of taxable income within a bracket.
• Effective rate: total tax divided by the relevant income base.
• Withholding rate: an amount withheld by a payer under a specific rule.
• IVA rate: transaction tax applied to covered goods, services, use of property, or imports.

Americans deciding how Mexican income tax affects their US return should also compare the Foreign Tax Credit with the Foreign Earned Income Exclusion rather than assuming the lower nominal rate creates the lower combined tax result.

Main tax types that matter

Four tax categories matter most in a practical income tax Mexico overview for Americans: ISR, IVA, real-property taxes, and taxes or withholding tied to particular transactions. The exact liability depends on residence and activity, so a person buying property can have a different Mexican tax profile from an employee or freelancer.

The 4 categories below separate recurring income taxes from consumption and property-related taxes.

 

How do taxes work in Mexico? Federal and local rules apply by tax type rather than through one all-purpose percentage. ISR is the main income tax, while IVA is a transaction tax and predial is imposed locally on real property.

Property owners should review our guide to buying property in Mexico as an American. A sale raises a different set of issues, covered in the TFX guide to selling property in Mexico as a US citizen.

Mexico taxes: what Americans need in 2026

Mexico taxes for Americans in 2026 depend first on 3 facts: residence, source of income, and type of income. Mexico income tax rules for a local employee are not identical to those for a freelancer, retiree, landlord, or nonresident, and Mexico tax laws can impose registration or reporting duties apart from US filing.

The following 3 profiles show why expat taxes in Mexico should be matched to the taxpayer’s actual activity:

• Employee: wages for work performed in Mexico can create Mexican income-tax exposure, with payroll withholding depending on the employment arrangement.
• Contractor: professional or business income can trigger Mexican registration, invoicing, ISR, and IVA rules depending on status and activity.
• Retiree: pensions, Social Security, investments, and property income need separate source and treaty analysis because FEIE does not apply to pension income.

A person researching Mexico expat taxes should not assume that a US employer, US bank account, or US client automatically makes income US-source for Mexican purposes. Where services are physically performed and how domestic law and the treaty classify the income can matter.

For retirement-specific issues, see our guide to retiring in Mexico. Remote workers can also review the Mexico digital nomad guide, while keeping immigration status separate from tax residence.

For expat taxes – Mexico cases involving income sourced in more than 1 country, do not classify the entire year from the location of the payer alone. Employment location, residence, entity structure, treaty rules, and foreign taxes actually paid can change both Mexican and US reporting.

NOTE! Mixed-source income can produce different answers for Mexico, the US Foreign Tax Credit limitation, and treaty treatment. Separate each income stream before calculating relief.

FEIE vs FTC: choose the right strategy

For the 2025 US tax year, a qualifying individual can exclude up to $130,000 of foreign earned income using Form 2555, while Form 1116 can provide a credit for qualifying foreign income tax subject to the statutory limitation. The better fit depends on income type, Mexican tax paid, self-employment tax, and other US tax benefits.

FEIE can exclude up to $130,000 of qualifying 2025 foreign earned income, while FTC instead uses eligible foreign income taxes to offset US income tax on the corresponding income.

 

Our Foreign Tax Credit guide explains how Form 1116 works when foreign income tax has already been paid or accrued.

Based on our client scenario at TFX: a qualifying employee earns $85,000 in Mexico during 2025 and has Mexican income tax withheld. Because $85,000 is below the $130,000 2025 FEIE ceiling, Form 2555 could potentially exclude all qualifying salary if the employee meets the tax-home and residence or presence requirements; FTC should still be modeled before choosing the approach.

Also, a self-employed consultant has $90,000 of net business income for 2025 and pays Mexican income tax. FEIE can reduce qualifying income subject to US income tax if the Section 911 tests are met, but it does not by itself erase Schedule SE liability; Form 1116 treatment should be evaluated separately.

 

Scenario A: Employee in Mexico

An employee earning $85,000 in Mexico during 2025 can have payroll tax withheld in Mexico and still report the salary on a 2025 US Form 1040. Form 2555 or Form 1116 may reduce US income tax, but the treatment depends on where services were performed, FEIE eligibility, and Mexican tax actually paid.

The following 3 records are particularly important for an employee:

• Payroll or wage records showing gross compensation and dates worked.
• Evidence of Mexican income tax withheld and paid.
• Travel and residence records supporting any Form 2555 claim.

A US employer can have reporting issues when an employee works abroad, so review TFX’s updated guide to working abroad for a US company. Employees receiving US payroll reporting should also understand how Form W-2 is used for expat returns.

Scenario B: Contractor or self-employed taxpayer

A contractor with $90,000 of 2025 net self-employment income can face 3 separate questions: Mexican ISR or IVA obligations, US federal income tax, and US self-employment tax. FEIE can affect qualifying foreign earned income for income-tax purposes, but Section 911 does not by itself remove Schedule SE tax.

The following 5 records help support a contractor return:

• Client invoices and payment records.
• Business expense receipts and bookkeeping.
• Mexican CFDIs and tax-payment records.
• Exchange-rate support for MXN-to-USD reporting.
• Foreign-account records for FBAR and Form 8938 testing.

TFX covers classification and reporting in its guide for independent contractors abroad and in its self-employed expat tax tips. The IRS also explains the Social Security tax consequences of working abroad.

The US–Mexico Social Security agreement was signed on June 29, 2004, but SSA’s current status material still lists the agreement as pending rather than in force. A self-employed American should not assume the agreement currently eliminates US self-employment tax.

Mexico tax rates in 2026: resident brackets and nonresident tiers

Mexico tax brackets differ sharply by residence and income category. For 2026, the annual resident ISR schedule contains 11 marginal bands from 1.92% to 35%; a separate Article 154 rule applies 3 tiers to specified wage income earned by nonresidents for services performed in Mexico.

The resident table below applies to the 2026 annual ISR tariff. The nonresident table is narrower: it covers the wage and subordinate-personal-service rule in Article 154 and should not be applied to every type of nonresident income.

TFX explains why the timing of foreign income and tax payments can affect the US credit calculation in its guide to reporting the timing of foreign income and foreign taxes.

Resident personal income tax brackets: tax year 2026

Mexico’s 2026 resident annual ISR tariff has 11 bands, beginning at 1.92% and reaching 35% above MXN 5,107,703.93. The tax is calculated using the band’s fixed amount plus the stated percentage applied to income above that band’s lower limit, rather than multiplying all income by the top rate.

For 2026, the top 35% resident marginal rate begins above MXN 5,107,703.93; lower portions of taxable income remain subject to the lower-band calculation.

NOTE! The table below is Mexico's resident ISR tariff for tax year 2026 (income earned January 1, 2026 onward), reported on the return filed in April 2027. If you're working out the tax owed on the 2025 Mexican annual return filed in April 2026, use the tax-year-2025 tariff instead – its top band starts at MXN 4,511,707.94, not MXN 5,107,703.93, and every lower band is set slightly below the 2026 figures shown here

 

These Mexico income tax brackets are a resident reference for the 2026 Mexican tax year. Your effective tax rate can be lower than your highest marginal bracket because the schedule applies progressively.

Nonresident income tax tiers

Article 154 contains 3 tiers for specified nonresident wage and subordinate-personal-service income where the service is performed in Mexico: the first MXN 125,900 is exempt, the next band through MXN 1,000,000 is taxed at 15%, and income above MXN 1,000,000 is taxed at 30%.

The 3 Article 154 tiers apply to covered wage-type income for services performed in Mexico, not to all nonresident income.

 

When no qualifying Mexican payer is required to withhold, Article 154 can require the taxpayer to pay through a return within 15 days after receiving the income. Withholding is not automatically the same as the final treatment of every other category of Mexican-source income.

VAT/IVA and sales tax in Mexico

Mexico’s standard federal IVA rate is 16% for covered sales of goods, independent services, temporary use or enjoyment of property, and imports. A border-region incentive can produce an effective 8% rate for qualifying taxpayers and covered transactions, but that incentive is conditional rather than Mexico’s nationwide IVA rate.

The following 4 everyday situations can involve IVA:

• Retail purchases of taxable goods.
• Professional or independent services.
• Certain rentals or temporary use of property.
• Imports of covered goods or services.

IVA is not structured like a US state retail sales tax. Businesses within the Mexican VAT system may charge IVA on taxable transactions and, subject to the rules, credit qualifying input IVA, so the amount shown on a receipt is part of a value-added-tax chain.

US–Mexico tax treaty

The US–Mexico income tax treaty entered into force on December 28, 1993, and is generally effective from January 1, 1994, for the original provisions. It coordinates taxing rights, residence, employment, pensions, investment income, and double-tax relief, but its saving clause allows the US to continue taxing US citizens in many situations.

The treaty does not make an American’s US filing obligation disappear. Article 1 contains the saving clause, while Article 24 provides double-tax relief and Article 4 contains the residence tie-breaker for individuals treated as residents of both countries.

A broader overview of how treaty rules work for Americans abroad is available in TFX’s US tax treaties guide.

What the treaty does

The treaty performs at least 4 practical functions: it coordinates residence under Article 4, assigns taxing rights for specified income, provides double-tax relief under Article 24, and offers a mutual-agreement procedure under Article 26. It can change an outcome, but only when the relevant article and eligibility requirements apply.

The following 4 treaty functions matter most in individual cases:

• Helps resolve dual treaty residence through the Article 4 tie-breaker.
• Sets specific rules for employment, independent services, pensions, interest, dividends, and other covered income.
• Provides mechanisms to reduce double taxation when both countries tax covered income.
• Allows competent authorities to address qualifying disputes through the mutual-agreement procedure.

The treaty does not generally eliminate Form 1040, FBAR, Form 8938, or other US information-reporting obligations merely because the taxpayer lives in Mexico.

When the treaty matters

Treaty analysis matters when at least 1 cross-border fact changes which country has primary taxing rights or how double taxation is relieved. Common triggers include dual residence under Article 4, employment physically performed in the other country, pension or Social Security payments under Article 19, and income taxed by both countries.

The following 4 cases commonly require article-by-article review:

• A person treated as resident in both countries under domestic rules.
• An employee who works physically in Mexico for a US employer.
• A retiree receiving US Social Security or a private employment pension while resident in Mexico.
• An investor receiving dividends, interest, gains, or property income across the border.

A treaty position should be matched to the actual income and article. The existence of the treaty does not substitute for filing a return or disclosure form required under US domestic law.

Pensions and Social Security

Article 19 contains distinct rules for private employment pensions, annuities, and Social Security or other public pensions. Under Article 19(1)(b), Social Security benefits and other public pensions paid by one country to a resident of the other country or a US citizen are taxable only in the paying country, subject to the treaty’s wording and other applicable provisions.

Article 19(1)(a) addresses pensions and similar remuneration for past employment, while Article 20 contains separate rules for government-service pensions. Retirement income therefore should not be grouped into one generic “pension” category without identifying the payer and the work or program that generated it.

Americans receiving retirement income can use TFX’s guides to US Social Security while living abroad and US retirement accounts while living overseas. The IRS also maintains current required minimum distribution FAQs.

How the treaty interacts with FTC and FEIE

The treaty, Form 1116, and Form 2555 solve different problems. FEIE applies only to qualifying foreign earned income from services, while pensions and Social Security are not earned income for Section 911; FTC can apply to qualifying foreign income taxes, subject to credit-category and limitation rules.

If the treaty gives exclusive taxing rights to one country for a payment, there may be no second-country income tax to credit. If both countries tax the income consistently with the treaty, Article 24 and US FTC rules may become central to the double-tax calculation.

TFX’s foreign pension reporting guide covers the separate US reporting issues that can arise with non-US retirement arrangements.

FBAR and FATCA Form 8938 for Americans in Mexico

FBAR and Form 8938 are 2 separate foreign financial reporting regimes. For 2025, an FBAR is required when the aggregate value of foreign financial accounts exceeded $10,000 at any point during the year, while Form 8938 uses higher thresholds that vary by filing status and whether the taxpayer lives abroad.

TFX’s FinCEN Form 114 guide explains the FBAR filing process. The IRS’s current FBAR filing requirements and Form 8938 guidance should be used for the current thresholds.

FBAR uses a single aggregate $10,000 account threshold, while Form 8938 thresholds for qualifying taxpayers abroad can begin above $200,000 at year-end.

 

Threshold and trigger checklist

The 2025 FBAR trigger is more than $10,000 in aggregate foreign financial accounts at any time, while a qualifying unmarried or nonjoint filer living abroad generally reaches the Form 8938 threshold above $200,000 at year-end or $300,000 at any time. Joint filers abroad use $400,000 and $600,000 thresholds.

The following 5 checks cover the principal individual thresholds:

• FBAR: Did the aggregate foreign-account value exceed $10,000 at any point in 2025?
• Form 8938, nonjoint filer abroad: Did specified foreign financial assets exceed $200,000 on December 31 or $300,000 at any point?
• Form 8938, joint filers abroad: Did specified foreign financial assets exceed $400,000 on December 31 or $600,000 at any point?
• Signature authority: Did you have authority over a foreign account even if you did not beneficially own it?
• Both forms: Does the same account fall within both reporting systems? One filing does not automatically replace the other.

When testing FBAR, you need the highest account value during the calendar year. TFX explains how to determine the maximum account balance for FBAR reporting.

File my FBAR

What accounts count?

FBAR can cover several kinds of foreign financial accounts, and Form 8938 reaches a broader class of specified foreign financial assets. The exact result depends on ownership and structure, so a Mexican bank account, brokerage account, pension arrangement, or fintech balance should not be classified only by its marketing name.

The following 5 account or asset categories deserve review:

• Mexican checking and savings accounts.
• Foreign brokerage and securities accounts.
• Certain foreign retirement or pension accounts.
• Accounts held through some foreign financial institutions or fintech providers.
• Accounts over which the taxpayer has reportable signature or other authority.

For broader disclosure questions, see TFX’s foreign financial asset reporting guide. Officers and employees should also review the rules for FBAR signature authority over foreign accounts.

Other Mexico taxes: property and inheritance

Two non-payroll issues regularly affect Americans in Mexico: real property and inheritances. Property can create municipal predial, rental, sale, or US reporting consequences, while Mexico’s federal Income Tax Law lists property received by inheritance or legacy as exempt income under Article 93(XXII), subject to other reporting or transaction rules.

Americans buying restricted-zone property may also encounter a bank trust structure. TFX’s fideicomiso guide for US taxpayers explains why the Mexican legal form does not by itself determine the US federal tax classification.

Property tax in Mexico: predial

Predial is a local real-property tax rather than a single national federal percentage. Because Mexico has more than 2,400 municipalities and local rules differ, owners should confirm the current assessed value, rate, discounts, and payment calendar with the municipality where the property is located rather than applying a nationwide rate.

A US owner also needs to separate annual ownership tax from Mexican tax on rent or a later sale. Those income and gain questions can produce both Mexican and US reporting even when the annual predial bill is modest.

Inheritance and estate taxes

Mexico’s federal Income Tax Law states in Article 93(XXII) that income received by inheritance or legacy is exempt from ISR. That federal income-tax exemption does not automatically resolve local transfer costs, later capital gains, basis questions, or the US tax and information-reporting consequences for a US beneficiary.

Americans receiving assets across borders should review TFX’s guide to estate tax issues for expatriates and its article on receiving a foreign inheritance as a US taxpayer. The IRS also publishes the federal estate tax rules.

Fideicomiso for restricted-zone property

A Mexican fideicomiso used to hold residential property in a restricted zone does not automatically have the same US tax classification as every trust. IRS Revenue Ruling 2013-14 concluded that the specific Mexican land-trust arrangement described in that ruling was not a trust under Treasury Regulation §301.7701-4(a), based on the limited trustee functions in that arrangement.

That ruling is fact-specific. If the trustee has additional duties, the arrangement holds other assets, beneficiaries have different rights, or the structure departs from the ruling’s facts, US information-reporting analysis can change.

The following 3 points should be confirmed for a fideicomiso:

• What property and other assets the arrangement holds.
• What substantive duties the Mexican bank or trustee performs.
• Whether the facts match Revenue Ruling 2013-14 closely enough for the same US classification.

Next steps

A Mexico-based American can organize the 2025 return filed in 2026 with 3 steps: confirm Mexican residence and income types, gather US and Mexican tax records, and choose the US filing treatment for FEIE, FTC, foreign accounts, and any business or entity reporting. Complex cases should be reviewed before forms are submitted.

Step 1: Confirm residence and income types

Start by classifying each income stream and determining whether Mexican Article 9 residence rules apply. Do not use a 183-day assumption as a substitute for the home and center-of-vital-interests analysis.

Step 2: Gather the supporting documents

Collect the 5 record groups described earlier, including tax-payment evidence and maximum foreign-account balances. TFX’s getting-started process explains how an expat return begins, while our tax document requirements show what information is commonly needed.

Step 3: Choose the filing treatment

Compare Form 2555 and Form 1116, then check FBAR, Form 8938, Schedule C, Schedule SE, and any entity forms that apply. Foreign accounts, contractor income, or conflicting residence rules can change the current-year filing. If you also have unfiled prior years, review the available US catch-up procedures below before assuming the 2025 return resolves earlier gaps.
