How to Open a Company in Mexico from Abroad: 2026 Guide

Can a foreigner own a company in Mexico?

Yes. Under Mexico's Foreign Investment Law, foreign investors may own up to 100% of the equity in the vast majority of economic activities. A limited list of sectors is reserved to the State or to Mexican nationals, or capped at a certain foreign ownership percentage. The first step is always to confirm your specific business activity is unrestricted for foreign capital.

Which entity type should you choose?

Three structures cover almost every case:

S. de R.L. de C.V. — A limited-liability company with partners and equity quotas. Popular with U.S. investors because it can often be treated as a pass-through entity for U.S. federal tax purposes. Requires at least two partners.

S.A. de C.V. — A stock corporation with shares and shareholders. Preferred when you plan to bring in investors, issue shares, or scale the business. Offers greater flexibility for capital structure.

SAS (Sociedad por Acciones Simplificada) — A simplified, low-cost company that can be formed online with a single shareholder, subject to an annual revenue cap. Useful for small or early-stage operations, though it has practical limits for foreign shareholders and may face constraints as you grow.

The right choice depends on your home-country tax position, your number of partners, and your growth trajectory. This merits one conversation with a Mexican corporate attorney before you file.

What are the steps to incorporate?

Step 1: Company name authorization. Request approval of your intended company name through the Ministry of Economy's portal. This reservation is typically valid for a set period.

Step 2: Draft and sign the incorporation deed. The bylaws (estatutos sociales) are signed before a Mexican notario público or corredor público. This document defines your corporate purpose, capital structure, shareholder obligations, management authority, and voting rights.

Step 3: Register with the Public Registry of Commerce. The incorporation deed is recorded in the registry serving your jurisdiction, giving the company legal personality and a registration number.

Step 4: Obtain the RFC and e.firma with SAT. The company receives its federal tax identification number (RFC) from Mexico's tax authority (Servicio de Administración Tributaria). Your company also obtains an electronic signature (e.firma) required to invoice, file tax returns, and open bank accounts.

Step 5: Register with the National Foreign Investment Registry (RNIE). Companies with foreign capital must register and file periodic reports to comply with foreign investment disclosure rules.

Step 6: Employer and operational registrations. If you will hire staff, register with the social security institute (IMSS). Open a corporate bank account once your RFC and e.firma are issued.

How long does it take, and what does it cost?

Incorporation typically takes around two to six weeks, depending on notary availability, processing of apostilles for foreign documents, and bank account opening timelines.

Costs are generally in the low thousands of US dollars for a straightforward company formation. The exact amount depends on the notario's fees, your capital structure, and whether any foreign shareholders require additional documentation. Incorporation costs do not include ongoing operational expenses like accounting or legal retainers.

These figures are indicative. Consult a qualified Mexican corporate attorney for a precise quote on your specific situation.

What does a foreigner specifically need?

Apostilled and translated documents. All shareholder documents (passport, corporate documents if a foreign entity is a shareholder) must be apostilled under the Hague Convention and translated into Spanish by a certified translator.

A power of attorney. This allows your Mexican attorney to complete filings and sign incorporation documents on your behalf without you traveling to Mexico.

A Mexican legal representative and tax address. The company must have a registered physical address in Mexico and a named legal representative for service of process and tax compliance.

RFC for foreign shareholders. Depending on the corporate structure, foreign shareholders may need to obtain a temporary or permanent RFC for Mexican tax purposes.

Tax treaty consideration. If you are a resident of another country, consult on permanent establishment (PE) issues and any tax treaty benefits between Mexico and your country of residence.

Do I need a Mexican partner?

Generally, no. In unrestricted sectors you do not need a Mexican partner or a Mexican shareholder. The legal requirement people sometimes confuse with local ownership is the legal representative and a registered business address in Mexico—these are not the same as ownership.

For the S. de R.L. structure, you technically need at least two partners, but both can be foreign individuals or foreign companies. A single shareholder can use an S.A. or a simplified SAS.

What comes after incorporation?

Running a Mexican company requires ongoing compliance. Monthly and annual tax filings, electronic invoicing (CFDI), accounting records, and bookkeeping are mandatory. If you have employees, you must manage payroll, social security (IMSS) contributions, and annual profit-sharing (Participación de Utilidades). Failure to comply incurs penalties and interest.

Most foreign-owned companies retain a local accountant (contador) and an attorney on a retainer basis to manage this calendar correctly from day one. Getting the compliance structure right early is far cheaper than correcting it later.

Frequently asked questions

Can I incorporate entirely from abroad? Yes. With a power of attorney and apostilled documents, your Mexican attorney can handle incorporation on your behalf. You do not typically need to be physically present in Mexico.

Can my foreign company be the shareholder? Yes. A foreign company can be a partner or shareholder in the Mexican entity, provided its corporate documents (certificate of incorporation, bylaws, shareholders' certificate) are apostilled and translated.

What is the difference between S. de R.L. and S.A.? The S. de R.L. uses equity quotas (participaciones) and is often chosen for U.S. tax pass-through treatment; the S.A. uses shares (acciones) and is better for raising capital and adding multiple investors. S.A. structures also offer more flexibility in governance.

Do I need a physical office? You need a registered tax address in Mexico. Whether you need physical premises depends on your specific activity. Many service-based companies start with only a registered address; others require a visible location for licensing or client relationships.

What if my sector has restrictions on foreign ownership? If your sector is restricted (such as fishing, mining, or certain telecoms), foreign ownership may be capped at a percentage or conditional on approval. Confirm this before incorporating. Your attorney will verify your specific activity against current rules.
