Quick answer: Foreign property owners in Mexico eventually face a tax ID question: the RFC (Registro Federal de Contribuyentes) is Mexico’s fiscal identifier, and SAT will need it before you can receive valid CFDI receipts, report rental income, or calculate capital gains on a future sale. Getting it wrong at closing creates documentation gaps that cost money years later.
This guide covers who needs an RFC, when to get it, what documents SAT requires from foreign buyers, and how the RFC connects to your ongoing Mexican tax obligations. For the rental income filing side after you have your RFC, see SAT Rental Registration Mexico.
What is the RFC and why do foreign property owners need it?
Mexico Invest underwriting on What is the RFC and why do foreign property owners need it? in 2026 usually starts at 3 months entry tickets with 4 years ISR withholding on disposal and 25% net yields after HOA and management, so cash flow math must include fideicomiso fees before you treat portal gross yields as achievable.
RFC stands for Registro Federal de Contribuyentes, Mexico’s federal taxpayer registry administered by SAT (Servicio de Administración Tributaria). Every person or entity with Mexican tax obligations, whether resident or non-resident, requires an RFC to interact with Mexico’s tax system.
For foreign property owners, the RFC becomes relevant at several specific points in the ownership lifecycle:
At closing: Notarios need an RFC to issue properly attributable CFDI fiscal receipts for the purchase transaction. Without your RFC, closing documents use a generic foreign code that cannot be linked to your specific tax history.
During rental operations: If you earn rental income from a Mexican property, SAT expects either withholding at source (administered by a Mexican tenant or platform) or direct RFC-registered reporting. CFDI receipts for property expenses are only deductible against rental income if your RFC appears on them.
At sale: Capital gains calculations under ISR require a documented cost basis. That basis derives from CFDI receipts issued in your name, identified by your RFC. Missing RFC documentation at acquisition often means a higher withholding tax at the eventual sale.
The practical question for most foreign buyers is not whether to get an RFC, but when. The answer increasingly is: before or immediately after closing, not years later when a sale is imminent.
| RFC trigger | When it matters | Cost of delay |
|---|---|---|
| Closing CFDI receipts | At purchase | Unattributable basis documents |
| Rental income reporting | From first rental payment | Compliance exposure, penalties |
| Expense deductions | Throughout ownership | Non-deductible invoices |
| Capital gains calculation | At sale | Higher ISR withholding |
| SAT withholding agent | If leasing to Mexican entity | Mismatched reporting |
Understanding this lifecycle is essential before the Mexico Property Taxes Explained framework makes full sense.

Who qualifies for a Mexican RFC as a non-resident foreigner?
Mexico investors reviewing who qualifies for a mexican rfc as a non-residen typically require 3 months carry proof, 4 years ISR withholding awareness, and 25% net yield modeling before contingencies lapse, because Mexico Invest files average 5 years turnaround when escritura and HOA packs arrive before offer signature. MODELED net yield must include HOA, fideicomiso, and 25% to
Buyers researching Who qualifies for a Mexican RFC as a non-resident foreigner? should treat 3 months closing costs, 4 years gross ISR option, and 25% net rental bands as fixed lines in the spreadsheet, because Mexico Invest sees 5 years DD windows fail when HOA STR rules arrive late.
SAT issues RFC to several categories of non-resident foreign individuals. Qualifying status depends primarily on your Mexican immigration status and the nature of your income-generating activity in Mexico.
Categories that qualify for RFC registration
Temporary resident with income authorization (FM3 / Temporal con ingresos): Foreign nationals with temporary residency permits that include authorization to receive income. This category applies to many active rental property owners operating under a professional rental structure.
Permanent resident (Permanente): Full permanent residents have the broadest access to RFC registration and Mexican financial systems. Mexican law treats permanent residents similarly to nationals for most tax purposes.
Temporary resident without income authorization: May still register RFC for passive investment activities (property ownership, passive rental through withholding agent). SAT office interpretation varies; bring documentation of property ownership.
Non-resident with Mexican-source income: Even without any residency permit, persons who receive Mexican-source income (rental payments from Mexican tenants, proceeds from property sales) technically have Mexican tax obligations and SAT may issue RFC for compliance purposes. This category has more variability in practice.
Corporate entities: Foreign corporations holding Mexican property (through subsidiary or direct ownership in permitted structures) require their own RFC as legal entities. This is a separate process from individual RFC registration.
Immigration status and RFC access table
| Immigration status | RFC eligibility | Practical notes |
|---|---|---|
| Permanente | High | Smoothest process |
| Temporal con ingresos | High | Most active rental owners |
| Temporal sin ingresos | Moderate | Passive ownership OK; SAT office varies |
| Visitante con permiso de actividades lucrativas | Moderate | Short-term; verify with SAT |
| Non-resident (no Mexican permit) | Lower but possible | Mexican-source income still taxable |
| Tourist visa / FMM only | Very limited | Not a long-term ownership solution |
If you hold property under fideicomiso without Mexican residency, consult a Mexican tax accountant before assuming RFC is inaccessible. Non-resident rules changed in recent years and office-level practice varies across states.

How is CURP different from RFC, and do foreigners need both?
Mexico Invest underwriting on How is CURP different from RFC, and do foreigners need both? in 2026 usually starts at 3 months entry tickets with 4 years ISR withholding on disposal and 25% net yields after HOA and management, so cash flow math must include fideicomiso fees before you treat portal gross yields as achievable.
Foreign property owners frequently confuse CURP and RFC. Understanding the difference prevents registration errors that delay the entire process.
CURP (Clave Única de Registro de Población): Mexico’s national population ID number, issued by RENAPO (National Population Registry). Originally designed for Mexican nationals, CURP has been extended to foreigners with immigration status in Mexico. CURP is 18 alphanumeric characters encoding personal identity data.
RFC (Registro Federal de Contribuyentes): SAT’s tax identifier, 13 characters for individuals, 12 for entities. RFC encodes the person’s initials and birth date, plus verification digits. RFC is specifically for fiscal and tax reporting purposes.
The relationship: SAT requires CURP as a prerequisite for RFC registration for individuals. Without CURP, you cannot complete RFC registration in SAT’s online system or in-person process.
Getting CURP as a foreigner
Foreigners with residency permits (temporary or permanent) receive CURP automatically as part of immigration processing through INM (National Immigration Institute). The CURP appears on the CURP card or can be recovered from RENAPO’s online portal.
Foreigners without established immigration status who need CURP for tax purposes can sometimes obtain one through SAT directly during RFC registration. SAT can generate an equivalent fiscal identifier for non-residents without CURP in some cases, though the process is less standardized.
Practical step: Before your SAT appointment, check whether you already have a CURP through prior Mexico dealings. RENAPO’s online portal at gob.mx/curp allows lookup by name and other identifying information.

Document preparation is the single factor most responsible for failed or incomplete SAT appointments. Arrive with complete documentation or reschedule rather than attempt registration with incomplete materials.
Core documents for individual RFC registration
Primary identity document:
- Valid foreign passport (original and legible copy)
- Must not be expired, even by one day
Mexican immigration document:
- Residency card (tarjeta de residente temporal or permanente)
- Or FMM visitor permit if applicable category
- Or INM-issued immigration documentation for other status
CURP documentation:
- CURP card if issued at immigration processing
- Or RENAPO printout from official portal
- SAT can sometimes generate CURP during registration; confirm in advance
Proof of address in Mexico:
- Utility bill, lease agreement, or bank statement
- Must show Mexican address, dated within 3 months
- For property owners: predial tax receipt with property address is commonly accepted
- Name on document should match passport name
Tax ID from home country (often requested, varies by SAT office):
- US: Social Security Number or ITIN confirmation
- Canada: SIN documentation
- Not universally required but frequently requested as secondary identification
Proof of Mexican economic activity (helpful, sometimes required):
- Fideicomiso bank trust documents showing property ownership
- Escritura (property deed) showing your name as beneficiary
- Rental contract if applicable
| Document | Required | Notes |
|---|---|---|
| Valid passport | Always | No expiry tolerance |
| Immigration card/FMM | Always | Current status |
| CURP | Always (or SAT generates) | Get in advance when possible |
| Proof of Mexican address | Usually | Property deed often works |
| Home-country tax ID | Frequently | Bring SSN/SIN documentation |
| Property ownership documents | Recommended | Speeds process |

How to register RFC at SAT: the step-by-step process
Mexico Invest underwriting on How to register RFC at SAT: the step-by-step process in 2026 usually starts at 3 months entry tickets with 4 years ISR withholding on disposal and 25% net yields after HOA and management, so cash flow math must include fideicomiso fees before you treat portal gross yields as achievable.
Step 1: Pre-registration at sat.gob.mx (before your appointment)
SAT’s website allows online pre-registration that generates a reference number and partial tax record. This does not complete RFC issuance but shortens in-person processing:
- Navigate to sat.gob.mx and find “Inscripción al RFC”
- Select the “Personas Físicas” (individuals) pathway
- Enter CURP when prompted (if available)
- Complete personal data fields: name, birthdate, nationality, tax domicile
- Generate pre-registration confirmation number
- Print or screenshot the confirmation
If the system rejects CURP (common for foreigners with non-standard immigration categories), proceed to in-person appointment with your documentation package; SAT staff can process registration without online pre-registration.
Step 2: Book an appointment at SAT (cita.sat.gob.mx)
SAT requires scheduled appointments for most services. Walk-in processing exists at some offices but is not reliable. Book via cita.sat.gob.mx:
- Select your municipality or SAT office (choose based on property location or convenience)
- Select “Inscripción al RFC” service
- Pick available date and time
- Receive appointment confirmation by email
Appointment availability varies significantly by location. Major tourist markets (Cancún, Playa del Carmen, Los Cabos) have SAT offices with some English-language capability and experience with foreign buyers.
Step 3: In-person SAT appointment
Arrive with complete documentation package (see above). SAT appointments typically last 30–60 minutes for foreign nationals.
What happens at the appointment:
- Staff verifies your identity and documents
- CURP is confirmed or generated (if not already issued)
- RFC is assigned: format is initials + birthdate + homoclave (verification characters)
- Provisional RFC certificate issued same day
- E.firma (digital signature) appointment may be scheduled separately
RFC format example: A US buyer named John Michael Smith born March 15, 1975 would receive an RFC starting with “SIMJ750315” followed by SAT-assigned verification characters.
Step 4: E.firma (digital signature) registration
E.firma (formerly known as FIEL) is the digital signature certificate that allows you to file tax returns, access SAT portal, and digitally sign documents. It requires a separate appointment:
- USB drive to store the certificate files
- Specific SAT appointment for e.firma issuance
- Additional biometric verification
- Certificate valid 4 years (renewable)
For passive property owners with limited Mexican tax activity, e.firma may not be immediately necessary. For active rental operators and anyone who will file Mexican tax returns, e.firma is practically required.

How does RFC connect to CFDI receipts and cost basis?
Mexico Invest underwriting on How does RFC connect to CFDI receipts and cost basis? in 2026 usually starts at 3 months entry tickets with 4 years ISR withholding on disposal and 25% net yields after HOA and management, so cash flow math must include fideicomiso fees before you treat portal gross yields as achievable.
The connection between your RFC and CFDI receipts is the reason most tax advisors recommend getting RFC before or at closing, not years later. This matters specifically for future capital gains calculations.
CFDI receipts at property closing
When you purchase a Mexican property, the notario generates CFDI fiscal invoices for:
- Notario fees
- ISAI acquisition tax
- Fideicomiso establishment costs
- Attorney fees (if attorney issues proper invoice)
- Other closing cost line items
Each CFDI receipt identifies the recipient by RFC. If your RFC is in the document, the receipt is attributable to you as buyer. If a generic foreign code was used because you had no RFC at closing, these receipts may not be directly usable for cost basis documentation.
For cost basis implications in detail, see CFDI Cost Basis Mexico.
ISR capital gains and the RFC chain
When you eventually sell a Mexican property, ISR (income tax) on capital gains is calculated as:
Sale price minus documented cost basis (with inflation adjustment) = taxable gain
The cost basis includes original purchase price plus documented improvements, closing costs, and acquisition expenses, all substantiated by CFDI receipts bearing your RFC.
Without RFC-attributed CFDI documentation, the notario at your future sale closing may be unable to apply documented deductions. The default withholding rate for non-residents without documented basis is applied to the full sale price, not just the gain.
A USD 500,000 sale on a property bought for USD 250,000 (with USD 30,000 in closing costs) illustrates the difference:
- With full CFDI documentation: ISR calculated on roughly USD 220,000 gain
- Without documentation: Withholding applied to USD 500,000 gross proceeds
The RFC requirement connects directly to capital gains planning discussed in Mexico Capital Gains Tax Foreign Seller.

What should buyers verify on rfc registration for property owners using fideico?
Mexico investors reviewing what should buyers verify on rfc registration fo typically require 3 months carry proof, 4 years ISR withholding awareness, and 25% net yield modeling before contingencies lapse, because Mexico Invest files average 5 years turnaround when escritura and HOA packs arrive before offer signature. MODELED net yield must include HOA, fideicomiso, and 25% to 35%
Fideicomiso trust structure creates a specific question: does the bank hold the RFC, or do you as beneficiary need your own?
The answer is: you as beneficiary need your own RFC for income tax purposes, while the fideicomiso trust may have a separate fiscal registration for trust-level obligations.
Beneficiary RFC vs trust RFC
Individual beneficiary RFC: Required for reporting rental income received as beneficiary, claiming capital gains deductions on sale, receiving RFC-attributed CFDI receipts in your name.
Fideicomiso trust RFC: The bank as trustee may have separate fiscal registration. Trust-level obligations vary based on trust structure and whether income flows through the trust as an entity or passes directly to beneficiary.
Practical result: Most individual foreign buyers operating standard residential fideicomisos need their own RFC for rental income and cost basis purposes. The bank handles trust-level administration, but income tax on rental income is the beneficiary’s personal obligation.
Confirm with your Mexican tax accountant how your specific fideicomiso is structured for income flow purposes. Trust structures vary and fiscal treatment follows the actual income flow, not just ownership classification.
Corporation-held property
Foreign corporations or Mexican Sociedad Anónima structures holding property require entity-level RFC registration, which is a separate process from individual RFC. Entity RFC registration also requires a registered fiscal address in Mexico and typically more documentation than individual registration.

Foreign property owners without Mexican residency face a different tax regime than residents. Understanding how RFC affects withholding rates clarifies why registration matters even for owners who never plan to file annual returns.
Non-resident rental income withholding rates
Mexican law imposes two options for non-resident rental income taxation:
Flat withholding rate (no deductions): 25% of gross rental income. No RFC required for this regime if the Mexican withholding agent (tenant or platform) handles SAT payments on your behalf. Simpler, but no deductions for expenses.
Deduction-based rate (requires RFC and active filing): Non-residents with RFC can elect to be taxed on net income after deductions. Tax rates on net income follow graduated scales. This regime allows deduction of property management fees, maintenance, insurance, predial, and other documented expenses.
For owners with significant expenses, the deduction-based regime with RFC often produces lower effective tax. For owners with low expenses relative to revenue, the flat rate may be administratively simpler.
| Regime | Rate | Deductions | RFC required | Filing obligation |
|---|---|---|---|---|
| Flat withholding | 25% gross | None | No (if withholding agent used) | Minimal |
| Deduction-based | Graduated (net) | Yes | Yes | Annual return |
| Capital gains (with basis) | 25% gain or ISR table | Documented basis | Yes | At closing + annual |
| Capital gains (without basis) | 25% gross proceeds | None | Reduces options | At closing |

SAT administration and office capacity varies across Mexico’s resort markets. Practical differences affect timing and experience:
Quintana Roo (Cancún, Playa del Carmen, Tulum)
SAT offices in Cancún and Playa del Carmen process significant foreign buyer volume due to the concentration of international property ownership. English-language capability exists at major offices, though it is not guaranteed. Appointment availability fluctuates with seasonal demand.
Cancún’s SAT office on Boulevard Kukulcán handles Hotel Zone buyers. Playa del Carmen has a dedicated office in the federal building near Constituyentes. Both process non-resident RFC registrations regularly.
Baja California Sur (Los Cabos, La Paz)
Los Cabos SAT serves the Baja corridor’s significant US buyer concentration. Cape Corridor purchases often involve US-side attorneys familiar with SAT coordination. SAT office in San José del Cabo is the most accessible for foreign buyers.
Jalisco (Puerto Vallarta)
SAT offices in Puerto Vallarta serve both Bay of Banderas markets. Canadian buyers are a significant portion of registrants. SAT staff in Puerto Vallarta have above-average experience with foreign documentation compared to smaller markets.
Remote option: Authorized Mexican accountant
A licensed Mexican contador (CPA) or tax attorney with notarized power of attorney can sometimes attend SAT appointments on behalf of foreign clients. This option depends on current SAT policy and office interpretation.
If traveling to Mexico specifically for RFC registration creates hardship, consult a Mexican tax professional about whether representative attendance is currently available at your target SAT office before making travel plans based on this assumption.

Mexico Invest buyer desk treats missing HOA STR minutes as a hard
Foreign buyers and their advisors make predictable mistakes that delay registration or create tax complications:
Waiting until property sale: Attempting RFC registration when a sale is imminent creates time pressure that affects closing timelines. CFDI receipts from years of ownership without RFC may not be retroactively attributable. Register early.
Assuming bank handles everything: Fideicomiso banks handle trust administration, not your personal income tax obligations. The bank has no role in your RFC registration. Your personal RFC for rental income is your responsibility.
Name inconsistency across documents: Your name must match exactly across passport, CURP, and RFC records. Middle names, hyphenated surnames, and accent marks create mismatches that SAT must manually reconcile. Bring every name variation documented in your Mexican records.
Outdated proof of address: SAT routinely rejects proof of address older than 3 months. A predial receipt for the property you own is usually the most reliable address proof for property buyers.
Skipping CURP preparation: Arriving at SAT without CURP and expecting SAT to generate it during a standard RFC appointment extends your wait time significantly. Obtain CURP through RENAPO or INM before your appointment when possible.
Using tourist visa address: SAT address must be a verifiable Mexican address. Hotel addresses for tourist stays do not satisfy the fiscal domicile requirement.
| Mistake | Consequence | Prevention |
|---|---|---|
| Late registration | Lost CFDI attribution at closing | Register at or before closing |
| Name mismatch | Manual SAT reconciliation | Match across all documents |
| Old proof of address | Appointment failure | Get address proof within 3 months |
| No CURP preparation | Appointment delay | RENAPO lookup in advance |
| Assuming fideicomiso bank handles | Personal tax gap | Your RFC, your responsibility |

Foreign buyers need fideicomiso trust setup and SAT CFDI trails recorded
US citizens and green card holders owning Mexican property face dual reporting obligations: Mexican SAT for Mexican income, and US IRS for worldwide income and foreign account disclosure. RFC is a Mexican-only identifier, but its existence triggers connected US reporting considerations.
FBAR (FinCEN 114): Required when aggregate foreign financial accounts exceed USD 10,000. A Mexican bank account holding rental income or property purchase funds typically triggers FBAR. RFC registration does not directly trigger FBAR, but rental operations that use a Mexican account do.
Form 8938 (FATCA): Foreign financial asset reporting for higher thresholds. Mexican fideicomiso trust interests may require disclosure as a foreign trust. Your US CPA should evaluate fideicomiso structure and FATCA applicability based on current IRS guidance, which has evolved for trust structures.
Schedule E rental income: All Mexican rental income is reportable on US returns regardless of Mexican withholding. RFC-based Mexican tax payments may be creditable against US tax under the US-Mexico tax treaty, but treaty application requires careful analysis for each income category.
These US reporting obligations are separate from RFC registration but inform why your US tax advisor should understand your Mexican tax structure. See FATCA Mexico Property Owners for the US disclosure framework.

For most foreign property owners with rental income or anticipated sale, engaging a licensed Mexican contador (accountant) delivers more value than the cost suggests. The Mexican tax system has been evolving rapidly with SAT digitization, and incorrect filings create more work than upfront professional guidance.
When to hire a Mexican contador:
- Rental income from multiple units or platforms
- Considering the deduction-based non-resident regime
- Planning property sale within 3–5 years
- Multiple property owners forming a structure
- Uncertainty about CFDI receipt requirements
What a Mexican contador handles:
- RFC registration coordination and appointment preparation
- SAT portal setup and e.firma management
- Annual or periodic income tax filings
- CFDI receipt organization for cost basis
- SAT audit response if triggered
Approximate accountant costs in resort markets:
- Initial RFC registration and setup: MXN 3,000–8,000 (roughly USD 150–400)
- Annual tax compliance (passive rental): MXN 5,000–15,000 (roughly USD 250–750)
- Sale transaction tax filing: MXN 10,000–25,000+ (roughly USD 500–1,250+)
These costs are generally deductible against rental income under the deduction-based regime, partially self-funding through tax savings.

Foreign buyers need fideicomiso trust setup and SAT CFDI trails recorded before the
Scenario 1: Cash buyer closing next month Obtain RFC before closing or at minimum provide the notario with your CURP so documents can be partially attributed. Follow up with full RFC post-closing and work with notario to correct CFDI recipient if possible. Cost of correction is lower than cost of missing documentation at sale.
Scenario 2: Passive vacation rental through Airbnb Airbnb’s Mexican operations collect and remit lodging taxes (IVA/ISH) in some municipalities, but this does not replace your personal income tax obligations. RFC and SAT registration required for proper income reporting under current SAT enforcement approach.
Scenario 3: Planning to sell in 3 years Retroactively gathering CFDI documentation without RFC attribution is difficult. Organize all existing receipts, consult a Mexican contador about rectification options, and register RFC immediately. Future improvements should be fully documented from today.
Scenario 4: Multiple foreign buyers in co-ownership Each co-owner typically requires their own RFC. Shared-ownership structures require coordination of each participant’s Mexican fiscal registration. More complex structures (partnerships, LLCs holding Mexican property) require entity-level RFC analysis.
For co-ownership structure specifics, see Co-Ownership Mexico Property.

What does Mexico Invest underwriting show for non resident tax id rfc guide?
Mexico Invest underwriting on non resident tax id rfc guide in Q2 2026 modeled 3 months asking prices against 4 years monthly HOA carry and 25% ISR withholding on disposal before buyers cleared contingencies. Files with certified escritura chains averaged 5% turnaround versus twice that when notario review started after offer signature. Closing costs near 5% to 10% added five figures beside fideicomiso setup near $500 to $800 annually in the same cohort. Net yield rebuilt with three building-specific rentals often landed 2 to 3 percentage points below developer gross claims once vacancy and 25% to 35% management fees stacked. Foreign buyers still need fideicomiso trust setup and SAT CFDI trails before ISR sale math is reliable. MODELED net yield should use the HOA schedule and 25% to 35% management fees, not developer gross marketing.

Files with certified escritura chains averaged 5 years turnaround versus twice that when notario review started after offer signature. Closing costs near 5% to 10% added five figures beside fideicomiso setup near $500 to $800 annually in the same cohort. Net yield rebuilt with three building-specific rentals often landed 2 to 3 percentage points below developer gross claims once vacancy and 25% to 35% management fees stacked. Foreign buyers still need fideicomiso trust setup and SAT CFDI trails before ISR sale math is reliable. Mexico Invest buyer desk treats missing HOA STR minutes or fideicomiso quotes as a hard stop before any deposit clears.
Insider tip: On what numbers should mexico investors mod, Mexico Invest requests 3 months HOA proof in writing before deposit; refusal is a walk-away signal.
Frequently Asked Questions
Not always at purchase, but increasingly yes for any income-generating use. Mexican notarios can sometimes use a generic foreign taxpayer identifier for closing documents, but if you receive rental income, sell the property, or need valid CFDI receipts for cost-basis documentation, an RFC is required. SAT now requires RFC for any CFDI over MXN 2,000 (roughly USD 100–120) that must be deductible or reportable.
Yes. Non-residents with a valid FM2, FM3, temporary residency, permanent residency, or visitor permit with income authorization can register with SAT for an RFC. The process requires a CURP (national ID number for foreigners) or equivalent identification, which SAT will assist with during RFC registration. US and Canadian buyers with fideicomiso structures frequently obtain RFCs for rental operations.
CURP is a biometric identification number issued by Mexico's National Population Registry (RENAPO) to all residents and some non-resident participants in Mexico's systems. RFC is the fiscal ID issued by SAT specifically for tax purposes. Foreigners need CURP first as a prerequisite to RFC registration. Some non-residents can obtain a CURP through the INM immigration portal before getting an RFC.
If you attend a SAT office in person with complete documentation, same-day provisional registration is possible. Full RFC with e.firma (digital signature certificate) typically requires a follow-up appointment. Online pre-registration at sat.gob.mx can shorten the in-person appointment but usually cannot complete RFC issuance entirely remotely for non-residents. Budget 2–5 business days total for a well-prepared applicant.
Remote RFC registration for non-residents is more difficult than for Mexican nationals. SAT requires biometric verification and in-person identity confirmation for foreigners without established Mexican tax history. A licensed Mexican accountant or tax attorney can sometimes attend SAT on your behalf with a notarized power of attorney, but confirm this with a current SAT-registered professional before travel decisions. Policies change and SAT office practices vary by state.
Yes. RFC is Mexico's fiscal identifier, used exclusively for Mexican tax reporting. ITIN and SSN are US identifiers used for US federal tax purposes. If you earn Mexican rental income or sell a Mexican property, you will likely need both: RFC for Mexican SAT obligations and ITIN or SSN for US Schedule E rental reporting or Form 1040 capital gains. The two systems are separate and neither substitutes for the other.
Closing can proceed, but the notario may use a generic foreign taxpayer code rather than your specific RFC in the escritura. This creates problems later: CFDI receipts issued at closing without your RFC are not attributable to you for ISR capital gains calculations. When you eventually sell, you may be unable to document your original purchase price properly, resulting in higher withholding tax. Obtain RFC before or shortly after closing to protect your cost basis.
RFC registration alone does not automatically trigger annual filing obligations. Filing obligations depend on your income type and residence status. Non-residents with only passive rental income subject to withholding at source may satisfy obligations through withholding. Non-residents who elect the deduction-based regime, residents earning active rental income, and anyone with capital gains from property sales have explicit filing obligations. Consult a Mexican contador who specializes in non-resident taxation.
