Financial Reporting in Mexico Wasn't Built for Your U.S. Headquarters

Every month, the finance team of a Mexican subsidiary sends a package to its U.S. parent. And every month, someone at headquarters asks the same question: why doesn't this match what we expected? Often nobody has made a mistake. The subsidiary is keeping books for several audiences at once, and each one follows a different rulebook.

How does financial reporting in Mexico work for a U.S. owned subsidiary?

A Mexican subsidiary usually reports in three layers at the same time.

The first serves the SAT (Servicio de Administración Tributaria, Mexico's tax authority). It requires electronic invoices, called CFDI (Comprobante Fiscal Digital por Internet), and a regular electronic submission of the company's accounting. This layer is about tax compliance, not about how the business is performing.

The second is the local financial statements, which follow the NIF (Normas de Información Financiera, Mexican Financial Reporting Standards). They are issued by CINIF, the Mexican board that sets accounting standards.

The third is group reporting: the format and policies your parent needs to consolidate the subsidiary, often U.S. GAAP (the accounting standards used in the United States).

Why can a subsidiary's numbers differ from U.S. GAAP?

Usually for a mix of reasons. The rulebooks are separate, so the same transaction can be recognized, measured or presented differently. The subsidiary and the group may use different accounting policies and estimates. The local books follow Mexican tax timing, such as the date of an invoice, while the group may want the same sale in another month. And some items exist only in Mexico, like PTU (Participación de los Trabajadores en las Utilidades), the legal obligation to share profits with employees.

A simple illustration, with assumed figures: a subsidiary shows a profit of 10.0 million pesos in its local books, and 8.0 million on the group's basis. Neither number is wrong. They answer different questions. Knowing exactly which differences apply to your company, and how to reconcile them every month, is a technical exercise that depends on your business and on both sets of standards.

What should you ask your finance team?

You do not need to be an accountant to start. Three questions tell you quickly where the risk is:

• Which rulebook does each report we receive follow, and who decided that?
• Do we reconcile local profit to group profit every month, with each difference explained?
• How long does our monthly close take, and what delays it?

If the answers are vague, the gap between your Mexican numbers and your group numbers is probably bigger than it looks.

Frequently asked questions about financial reporting in Mexico

Is the accounting sent to the SAT the same as financial statements?

No. It is a tax submission in a format the SAT defines. Financial statements show performance and financial position under accounting standards.

Who sets Mexican accounting standards?

CINIF, the Consejo Mexicano de Normas de Información Financiera y de Sostenibilidad, issues the NIF.

What is a CFDI?

It is Mexico's electronic invoice, the tax document for a transaction.
