What should I do if the SAT is auditing me?

Receiving a document from the SAT requires identifying what the authority is requesting before responding. An invitation letter and the start of an audit should not be treated as the same procedure. Begin by gathering the complete document and the record of how and when it was received.

Read the notice and record the deadlines

Check the issuing authority, the taxpayer addressed, the periods and the taxes identified. Keep the attachments and acknowledgment of receipt. The response deadline depends on the notice and its service; a general guide cannot establish that date. Ask a professional to review the document and determine the applicable timetable.

Organize the transaction file

Match the request to the accounting records and tax returns. Gather contracts, invoices, bank statements and evidence of goods delivered or services performed, as appropriate to the transaction. PRODECON recommends keeping physical and digital records that substantiate transactions and support responses to authority requests. Avoid submitting files without an index explaining how they address each requested item.

Prepare a consistent response

Coordinate the accounting and legal review before submitting information. The response should address the scope of the request and the available records. If disagreements arise with the authority, review the options available at that stage with your adviser. PRODECON provides guidance on acts of federal tax authorities; the appropriate approach depends on the facts and the specific procedure.
