How to register a company online in Mexico 2025
Starting a business in Mexico has never been easier — at least that’s what the government claims with its digital platforms. But is registering your company online in 2025 really that simple? The answer is: yes… and no.
The promise of digital Mexico
In 2025, entrepreneurs can now register certain types of companies entirely online. The most common legal form is the SAS (Sociedad por Acciones Simplificada), designed for small businesses and startups. This simplified system allows business creation through the Secretaría de Economía portal.
All you need is:
Your RFC (Registro Federal de Contribuyentes) obtained from the SAT
Your e.firma (advanced electronic signature)
A CURP (unique population registry code)
With these, you can legally constitute your company in just a few days.
The hidden difficulties
While the platform looks simple, many entrepreneurs discover pitfalls:
Banking: Most banks still require in-person procedures to open a business account, slowing the process.
Notarial services: For companies larger than SAS (like an S.A. de C.V.), you still need a notary.
Tax obligations: Once you register, SAT expects monthly declarations — with penalties for errors.
At abogadomex.mx, we’ve seen entrepreneurs fined or delayed because they assumed “online registration” meant “no bureaucracy.”
The lawyer advantage
A skilled attorney can:
Recommend the best company structure for your case (SAS, S.A. de C.V., etc.)
Handle filings with SAT and Secretaría de Economía
Prevent costly errors in accounting, shareholder agreements, or permits
Sometimes paying for expert help saves you months of frustration.
The final verdict
Registering a company online in Mexico in 2025 is possible and faster than ever. But don’t be fooled — digitalization doesn’t erase legal complexity. Take advantage of the tools, but also be smart: get informed, and don’t hesitate to seek legal guidance.
