Opening a business in Mexico? We compare the most common company types under the General Law of Commercial Companies, walk through the incorporation process step by step, and explain what foreign investors should watch out for.
Forming a company in Mexico is an accessible process for both nationals and foreigners. The General Law of Commercial Companies (Ley General de Sociedades Mercantiles, LGSM) governs the types of companies; the two most common are the Stock Corporation (Sociedad Anónima, S.A. de C.V.) and the Limited Liability Company (Sociedad de Responsabilidad Limitada, S. de R.L. de C.V.). There is also the Simplified Stock Company (Sociedad por Acciones Simplificada, SAS), designed for entrepreneurs. This guide helps you choose and complete the process.
Which type of company suits me?
- S.A. de C.V.: the most versatile for businesses looking to grow or attract investment. Its capital is divided into easily transferable shares; it requires a minimum of two shareholders. The "de C.V." (variable capital) allows the capital to be increased or decreased with greater flexibility.
- S. de R.L. de C.V.: ideal for closely held or family businesses. The capital is divided into membership interests (partes sociales) (not shares), and their transfer requires the consent of the other partners, which gives control over who joins. It allows a maximum of 50 partners. It is often preferred by U.S. investors because of its tax treatment there.
- SAS: it can be formed online and without a notary, even with a single shareholder, through the federal government portal. It is designed for small businesses with income below a certain threshold and does not allow legal entities (companies) as partners.
In both (S.A. and S. de R.L.), the partners' liability is limited, in principle, to the amount of their contributions.
Step by step to form the company
- 1. Name authorization. You request from the Ministry of the Economy the permit to use the company's name (to verify that it is not already taken).
- 2. Articles of incorporation before a notary or public broker. These define the corporate purpose, the capital, the partners, the management, and the bylaws. If there are foreign partners, the foreigner admission clause is included.
- 3. Registration for the RFC (federal taxpayer ID) with the SAT (tax authority) and obtaining the company's e.firma (electronic signature).
- 4. Registration with the Public Registry of Commerce. This provides publicity and enforceability against third parties.
- 5. Additional registrations: enrollment with the IMSS (social security institute) if you are going to hire staff, municipal notices, and permits according to the line of business.
Special rules for foreign investors
Mexico generally allows 100% foreign capital in most sectors, with some activities reserved or limited by the Foreign Investment Law (Ley de Inversión Extranjera). Points to watch:
- Include the foreigner admission clause in the bylaws.
- Register the company with the National Registry of Foreign Investments (Registro Nacional de Inversiones Extranjeras, RNIE) when foreign partners take part.
- Verify that the sector is not one reserved to the State or to Mexican nationals.
- Foreign directors or legal representatives operating in Mexico must regularize their immigration status.
Documents you will need
- ID of the partners (a passport in the case of foreigners) and, where applicable, CURP (national population registry ID) and RFC.
- Proposed company name.
- A tax domicile in Mexico.
- Definition of the corporate purpose, capital, and management bodies.
Timeframes and costs
A SAS formed online can be incorporated in a few days and at low cost. An S.A. de C.V. or S. de R.L. before a notary usually takes 1 to 4 weeks, with costs that depend on the notary's fees, the registration duties, and the capital. After the reforms, there is no rigid legal minimum capital for the S.A., but it is advisable to set one in line with the operation.
Common mistakes
- Choosing the company type without analyzing the tax impact in the investor's home country (the S. de R.L. is often better for U.S. partners).
- Drafting too narrow a corporate purpose, which later limits the business.
- Forgetting to register with the RNIE when there is foreign capital.
- Failing to enroll workers with the IMSS, with the resulting fines.
Notary or public broker
The articles of incorporation can be executed before a notary or before a public broker (corredor público); both grant public faith. The broker specializes in commercial acts and is often a nimble alternative for forming companies, while the notary also covers civil and real estate matters. Choose based on the complexity and the additional procedures you anticipate.
Obligations after incorporation
Forming the company is just the beginning. The company must keep accounting records, issue and receive invoices (CFDI), file monthly and annual returns, maintain its corporate books (minutes of meetings and the register of partners or shareholders), and, if it has employees, comply with the IMSS, Infonavit (housing fund), and the corresponding withholdings. Neglecting these obligations leads to fines and, in serious cases, liability for the directors.
Frequently asked questions
Can a foreigner be the sole partner?
Yes, in several cases. The SAS allows a single shareholder, and commercial companies can have 100% foreign capital in most sectors, except for activities reserved or limited by law.
Which is better, S.A. de C.V. or S. de R.L.?
It depends on your plans. The S.A. de C.V. makes it easier to attract investment and transfer shares; the S. de R.L. gives more control over who joins and is often preferable tax-wise for partners from the United States.
Conclusion
The legal form you choose affects taxes, control, and the ease of receiving investment. For a small venture, the SAS is nimble; for serious operations or those with foreign capital, the S.A. de C.V. or the S. de R.L. de C.V. offer more solidity. Before incorporating, consult a corporate lawyer and an accountant who can assess your case and the most suitable tax structure.
