## Mexican rules for accounting firms

The IMCP code of ethics requires confidentiality, and SAT taxpayer data stays out.

Any personal data left in the records falls under Federal Law on the Protection of Personal Data Held by Private Parties (2025); the [Mexican privacy steps](https://origindatapartners.com/sell-company-data/mexico#rules) apply to every industry. Before anything leaves, exclude:

- Client financial statements and tax identifiers.
- Material covered by professional confidentiality rules.
- Data from client systems you accessed under engagement letters.

## Can an accounting firm license client working papers?

Only with client identities removed and only where professional confidentiality rules and engagement letters allow it. Firm-wide procedures, close checklists and review-note patterns are the lower-risk core.
