Companies operating in Mexico need regular entity health checks to ensure compliance with Mexican regulations. An entity health check in Mexico serves as comprehensive due diligence Mexico companies require to avoid penalties and maintain good standing with authorities. Annual reviews protect your subsidiary or branch from unforeseen risks after company formation in Mexico. This guide explains why a proactive compliance audit is a critical business practice and details the primary areas of review for any company operating in Mexico.
An entity health check is a comprehensive diagnostic of a company’s statutory records and obligations. It is designed to identify and rectify any compliance failures, such as unrecorded shareholder resolutions or incorrect social security payments, before they can lead to significant penalties from the authorities.
An entity health check in Mexico provides comprehensive corporate due diligence Mexico businesses need to assess critical compliance elements. This review, essential for Mexico entity verification, examines fiscal, legal, and operational activities to identify discrepancies requiring remediation.
This health check reflects what, if anything, your company needs to do to stay compliant with local law. Sometimes a company’s Directors cannot accurately assess the overall compliance status, or don’t possess the legal or financial know-how to understand their compliance requirements in Mexico. It pays to get a professional external auditor to conduct this review on the company’s behalf.
Expert Tip: Formalizing Corporate Resolutions
From our experience, a very common compliance gap in Mexico is the failure to formalize corporate resolutions. It is not enough for the shareholders to simply agree on a decision. All major corporate acts—such as approving annual financial statements, appointing a new director, or declaring dividends—must be documented in the minutes of a formal shareholder meeting (Asamblea de Accionistas).
These minutes must then be recorded in the official, sealed corporate minute book. A health check must include a thorough review of these books to ensure a complete and unbroken record of corporate decisions exists, as this is essential for legal validity and good governance.
This audit verifies that the company’s public deed is correctly registered and that all resolutions from shareholder meetings have been properly recorded in the official corporate books.
This involves a comprehensive review of all monthly and annual tax filings (ISR, IVA) and the electronic accounting records submitted to the SAT to confirm accuracy and timeliness.
This review checks that the company is correctly registered as an employer with the IMSS and that all monthly social security and housing fund (INFONAVIT) contributions have been paid.
This check verifies that all required reports have been filed with the National Registry of Foreign Investments and that the company is complying with federal data protection laws.
The checks review all fiscal, legal and other operational activities of a company, and raise any discrepancies or issues to be remedied. This includes:

Routine legal due diligence Mexico proves essential for:
EXPERT TIP: Schedule your entity health check in February or early March to allow time for corrections before the April 30 deadline for ordinary shareholder meetings required by Mexican Corporate Law (LGSM).
Corporate compliance in Mexico is broken down into several areas.
Business objectives: Does the company follows its initial vision and maintain its company policies? The company must follow the strategies and plans laid out in its own policies and constitution. Companies must follow their constitutive bylaws (estatutos sociales) filed with the Public Registry of Commerce. Any deviation requires formal amendment through shareholder resolution.
Legal due diligence Mexico requirements include: contract reviews with Mexican counterparties, maintenance of corporate books (libros corporativos), lease agreements compliant with Mexican Civil Code, intellectual property registrations with IMPI, and labor contracts following Federal Labor Law (LFT).
Finance and cash flow: The company must undertake regular reviews of its finances and bookkeeping. These are essential for decision making for the Directors and members of the board. The company’s financial experts must ensure that cash flow meets the requirements to generate a positive cash flow. Mexican companies must maintain electronic accounting (contabilidad electrónica) for SAT and manage CFDI invoices properly.
Human Resources: For many companies, people are their most important asset. A detailed entity health check should therefore also include a plan for optimal development of human resources practices to find and manage the best people to run the business. HR practices must align with Federal Labor Law (Ley Federal del Trabajo), IMSS and INFONAVIT registration requirements, and profit sharing (PTU) obligations.

Along with corporate compliance, a company must comply with two main areas that are vital for the proper function of the company: legal and fiscal compliance.
It is crucial to regularly review the company’s legal corporate activity in Mexico. Documentation that would fall under this area of an entity health check in Mexico include (but is not limited to):
Corporate due diligence Mexico mandates regular review of:
In Mexico, all companies must hold an ordinary shareholders meeting once a year. For this, all information regarding the increase of capital stock, admission of new shareholders, and other agreements reached at the assembly must be stated and notarized to comply with Mexican corporate regulations.
Fiscal Mexico entity verification represents the most critical component, including complete audit of SAT compliance status.
The SAT produces a certification of good standing to a company, called ‘Opinión Del Cumplimiento de Obligaciones Fiscales’. This certification confirms whether or not the company is in full compliance with all mandatory fiscal contributions in Mexico. If applicable, it will outline any outstanding fiscal obligations the company has not complied with.
A negative certification can affect a company’s credit score and result in visits from the fiscal authorities, fines, surcharges, and other complications.
Mexican companies must meet critical fiscal deadlines including monthly declarations by day 17 of each month, annual tax returns by March 31, and both ISR provisional payments and VAT returns monthly by day 17.
EXPERT TIP: Request your SAT compliance opinion quarterly. Negative opinions affect credit ratings and trigger tax authority audits. The certificate expires after 30 days, so timing matters for transactions.”
For the fiscal entity health check in Mexico, it’s important to keep in mind that for any legal activities such as liquidation, dissolution, and merging, the company must be fully compliant with its fiscal obligations in order to proceed.

Manufacturing companies operating as maquiladoras need quarterly IMMEX compliance reviews, customs audit preparation, and transfer pricing documentation. Service companies must ensure professional services tax compliance, meet digital services VAT requirements, and complete foreign service provider registration. Retail operations require PROFECO compliance for consumer protection, electronic invoicing through CFDI, and adherence to cash transaction limits.
Professional corporate due diligence Mexico requires experienced auditors familiar with Mexican regulations. Conducting routine entity health checks protects your business from penalties imposed by SAT, IMSS, and other government institutions.
