SAT Audit: What to do (and what to avoid) from day one

Receiving a notice of review from the tax authority almost always generates the same reaction: concern. However, an audit is not, in itself, a conviction. It is a procedure with rules, deadlines, and rights for the taxpayer. The difference between a favorable and a costly outcome is often defined by how one acts during the initial days.

Understanding the Type of Review

Not all audits are the same. A desk review (revisión de gabinete), a home visit (visita domiciliaria), or an electronic review (revisión electrónica) have different scopes, deadlines, and dynamics. Precisely identifying which procedure is being faced is the first step to responding correctly; acting without that clarity leads to errors.

Deadlines are Rights, Not Mere Formalities

The tax procedure is full of deadlines, both for the authority and for the taxpayer. Many of these deadlines are, in reality, guarantees in favor of the company. Allowing them to pass or responding out of time can close doors that cannot be reopened later. Maintaining rigorous control of the calendar is essential.

What to Avoid

There are recurring errors that unnecessarily complicate the case: submitting information without prior analysis of what is being provided, responding in an improvised manner, ignoring requests, or attempting to resolve the matter without a clear strategy. Cooperation with the authority is important, but cooperating does not mean waiving rights or providing more than what is required.

Documentation is the Best Defense

A significant part of an audit's outcome depends on the solidity of the documentation. Having accounting records, vouchers, and supporting documentation in order transforms a review into a manageable process. The lack of backing, however, usually results in adjustments.

Strategy from the Outset

Every response submitted to the authority becomes part of a file that may eventually reach defense instances. Therefore, it is advisable to act from day one with a strategic vision of the complete procedure, rather than reacting request by request.

Conclusion

An audit is largely won or lost based on how it is conducted. Understanding the procedure, respecting deadlines, safeguarding documentation, and acting strategically from day one is what allows facing it with certainty instead of fear.
