Business Permits & Incorporation for Foreigners in Oaxaca

Good to know

Good to Know

  • Most foreigners do not need a Mexican business partner to incorporate — full foreign ownership is allowed in the vast majority of sectors; only a specific list of restricted/capped activities (e.g. domestic land transport, certain professional services, media, aviation) require Mexican majority ownership or exclude foreign capital entirely.
  • The notario público is the central figure in Mexican incorporation — almost nothing is 'final' until it's been formalized in front of one, and this step (plus the associated fees) is usually the single biggest cost driver.
  • If you won't be in Mexico to sign in person, you can incorporate remotely by granting a Power of Attorney to a legal representative, but expect extra cost and time for apostille and certified Spanish translation of your home-country documents.
  • A 'virtual office' will not satisfy Mexico's fiscal address requirement — the law requires a real physical address where your accounting/corporate books are kept, so budget for renting a registered address if you don't already have one.
  • If your company has more than 49% foreign ownership, don't forget the National Registry of Foreign Investments (RNIE) filing — it has a strict 40-day deadline from your incorporation date.
  • The Sociedad por Acciones Simplificada (S.A.S.) can be set up online quickly and by a single founder, but it's capped at roughly MXN 5 million in annual income and shareholders must be individuals — not a fit for many growth-stage businesses.
  • Mexico's flat 30% corporate ISR rate and the RESICO simplified regime are federal rules set by SAT — they apply the same way in Oaxaca as anywhere else in Mexico; there is no Oaxaca-specific corporate tax break.
  • If you're freelancing as an individual, being a shareholder in your own Mexican company (even a tiny one) disqualifies you from the low-rate RESICO regime for your personal income — this trips up nomads who try to do both at once.
  • A local Mexican accountant (contador) is close to essential for either route — SAT's electronic CFDI/e.firma/buzón tributario system is unforgiving of missed monthly deadlines, and penalties/surcharges accrue quickly.
  • Dividends paid out of a Mexican company to a foreign owner face a 10% withholding tax unless a tax treaty between Mexico and your home country reduces or eliminates it — worth checking before assuming take-home profit equals post-30%-tax profit.

Common Legal Entities

  • Sociedad Anónima (S.A. De C.V.)
    Description
    Corporation-style entity; the most regulated and commonly used structure for larger or long-term operations; requires a minimum of two shareholders.
  • Sociedad De Responsabilidad Limitada (S. De R.L. De C.V.)
    Description
    LLC-equivalent entity limited to a maximum of 50 partners; common for small and medium foreign-owned operations.
  • Sociedad Por Acciones Simplificada (S.A.S.)
    Description
    The simplest structure, can be formed online by a single shareholder and gets a response within 24 hours, but annual income is capped (around MXN 5 million, adjusted yearly) and shareholders must be individuals (natural persons), not other companies.

Business Tax And Structure Options

Practical Freelancer Vs Company Summary
For a solo digital nomad or consultant, registering as a persona física (freelancer) under RESICO is typically the simplest and cheapest path, provided annual income stays under the roughly MXN 3.5 million ceiling and the person isn't also a company shareholder. Forming a full persona moral (S.A. de C.V.) makes more sense when hiring local staff, seeking limited liability, bringing in outside investors, or when income/complexity outgrows RESICO's thresholds — but it carries materially heavier bookkeeping, monthly filing, and (for foreign-owned entities) the flat 30% corporate rate rather than any simplified small-business rate.
Scope Note
Covers local business tax implications and the freelancer/sole-proprietor vs. full-company decision for a foreign-owned business operating in Oaxaca.

Structure Options

Full Company

Corporate Tax Rate
MX$30
Liability
Limited liability — the company is a separate legal taxpayer from its shareholders.
Legal Forms
Most foreign investors incorporate as an S.A. de C.V. (standard corporation with variable capital) or S.A.P.I. de C.V. (a more flexible governance structure often used for start-ups seeking outside investors).
Dividend Withholding
Dividend distributions from a Mexican corporation to foreign shareholders are subject to a 10% withholding tax unless a tax treaty exemption applies.

Filing Obligations

  • Monthly provisional ISR payments, generally due by the 17th of the following month
  • Annual ISR return for the prior fiscal year due by March 31
  • Monthly VAT (IVA) returns, generally due by the 17th
  • All invoicing done via CFDI e-invoices tied to the company's RFC and e.firma digital signature
  • Payroll withholding and employer social security (IMSS) / housing fund (INFONAVIT) contributions if the company has employees

Resico For Small Companies

Eligibility Ceiling
MX$35,000,000
Foreign Ownership Restriction
This small-company RESICO regime requires that all partners/shareholders be Mexican tax-resident individuals, which in practice excludes most foreign-owned companies — a foreign-owned S.A. de C.V. will generally fall under the standard 30% Régimen General instead.
Description
A RESICO variant exists for small legal entities (personas morales) with annual income under roughly MXN 35 million, taxed at 30% on profit but with a cash-flow benefit (tax is triggered when payment is collected, not when invoiced).

Sole Proprietor Freelancer

Liability
Unlimited personal liability — there is no legal separation between the individual and the business.
Legal Form
Persona Física con Actividad Empresarial o Profesional — registers individually with SAT (Mexico's tax authority) under an RFC (tax ID), no separate legal entity is created.
Practical Note
Freelancing as a persona física is the lower-cost, lower-compliance route for a solo consultant/service provider, but exposes personal assets to business liability and is not usable if the individual is also a shareholder of a company.

Tax Regime Options

Resico Pf

Isr Rate Note
Tax is charged on gross income actually collected (not net profit), with rates ranging from roughly 1% to 2.5% depending on income level, with no personal deductions allowed under this regime.
Filing
Monthly provisional/definitive ISR payments due by the 17th of the following month; CFDI (electronic invoices) must be issued for all income; an active e.firma (digital signature) and tax mailbox (buzón tributario) are required.
Exclusions
A person cannot use RESICO if they are also a partner/shareholder of a Mexican legal entity (persona moral), or if their only income is salary.
Eligibility Ceiling
MX$3,500,000
Description
Régimen Simplificado de Confianza for individuals — a simplified regime for those with business, professional-fee, or rental income.

Regimen General Pf

Isr Rate Note
Progressive personal ISR brackets apply (up to roughly the mid-30s percent range at the top bracket), calculated on net profit after allowable business deductions, rather than a flat low rate on gross income.
Filing
Monthly provisional ISR payments plus an annual return; deductible expenses must be properly invoiced via CFDI.
Description
Standard individual regime for business/professional income above the RESICO threshold, or for those who opt out of RESICO.

Shared Tax Layers Both Structures May Face

VAT
Mexico's VAT (IVA) is 16% nationwide (Oaxaca is not in the reduced-rate northern border zone), charged on most goods and services and filed/paid monthly, separate from whichever ISR regime applies.
State Payroll Tax
On top of federal taxes, Mexican states levy their own payroll tax (impuesto sobre nómina) on salaries paid, commonly cited in the roughly 1–3% range depending on the state; the exact current Oaxaca-specific rate should be confirmed directly with a local accountant, as it was not independently verified against Oaxaca's state tax code for this entry.
Municipal Property Tax
Predial (property tax) applies at the municipal level if the business owns real estate, separate from federal ISR.

Incorporating a business in Mexico as a foreigner (including in Oaxaca) follows the same federal legal framework used nationwide — Oaxaca does not have a separate incorporation regime, but the state's own Public Registry of Commerce office (part of the Instituto de la Función Registral del Estado de Oaxaca, IFREO) is where the notarized incorporation deed gets registered locally.

Timeline

Typical Range
4 to 12 weeks for the core incorporation (name approval, notarization, Public Registry filing, RFC), with an additional 2–3 weeks commonly needed for post-incorporation registrations (RNIE, SIEM, IMSS).
Notes
Name approval is meant to take only a few days but can be delayed by regulatory backlogs or name rejections. RNIE registration for foreign-owned companies has a hard deadline of 40 days after the incorporation date. Document apostille and Spanish translation requirements for foreign shareholders can add extra time.

Step By Step Process

Step By Step Process

  • Choose the legal entity type (S.A. de C.V., S. de R.L. de C.V., S.A.S., branch, etc.) based on ownership structure and business plan.
  • Reserve the company name (denominación o razón social) with the Secretaría de Economía — typically 3–10 name options are submitted for approval.
  • Draft the company bylaws / articles of incorporation (Acta Constitutiva), defining shareholders, capital contributions, management structure, and corporate purpose.
  • Sign the Acta Constitutiva before a Mexican notario público (or corredor público), who formalizes and notarizes the deed. Non-resident shareholders who are not physically present typically act through a Power of Attorney (apostilled and translated into Spanish).
  • Register the notarized deed with the state's Public Registry of Commerce (in Oaxaca, this is filed through IFREO) to give the company legal personality.
  • Obtain the company's Federal Taxpayer Registry (RFC) and e.firma (electronic signature) from the Servicio de Administración Tributaria (SAT), generally required within 30 days of incorporation.
  • If there is foreign ownership above 49% of capital, register with the National Registry of Foreign Investments (RNIE) — this must be done within 40 days of the incorporation date.
  • Register with the Mexican Business Information System (SIEM).
  • Secure a physical fiscal address in Mexico (virtual addresses are not legally accepted) and, if hiring staff, register with IMSS (social security) and the housing fund (INFONAVIT).
  • Open a Mexican corporate bank account in the company's name, which usually requires a minimum capital deposit and, for foreign-owned entities, extra bank verification steps.
  • Obtain any state/municipal operating permit (aviso de operación / licencia de funcionamiento) from the Oaxaca de Juárez municipal government for the specific business premises and activity.

Documents Typically Required

Documents Typically Required

  • Valid passport(s) of all foreign shareholders/directors
  • Proof of legal stay in Mexico (FMM tourist permit or residency) if signing the Acta Constitutiva in person; not needed if incorporating remotely via a legal representative
  • Proof of address for shareholders (utility bill or bank statement, generally under 2 months old)
  • Apostilled and Spanish-translated corporate documents if a shareholder is itself a foreign company
  • Power of Attorney naming a legal representative (Apoderado Legal) if shareholders are not resident in Mexico
  • Proof of the company's Mexican fiscal address

Local Partner Or Sponsor Requirement

No local Mexican partner or sponsor is legally required for most business activities — foreigners can own 100% of most Mexican company structures. However, a handful of sectors restrict or cap foreign ownership: some activities (e.g. domestic land passenger/cargo transport, certain professional services, development banking) are reserved for Mexican nationals, and others cap foreign participation at set percentages (for example, limits around 10% in production cooperatives, 25% in domestic air transport, and up to 49% in sectors like explosives manufacturing, print media, fishing, and broadcasting). Outside those specific restricted activities, most standard company types (S.A. de C.V., S. de R.L. de C.V.) can be wholly foreign-owned.
