Mexico's Tax Administration Service (SAT) is the Mexican fiscal authority and the practical reference for any company operating in Mexico. Articles tagged with SAT cover what this authority requires regarding mileage reimbursement: how to tie the expense to the correct CFDI, how to apply the 50-km rule from LISR Article 28, how to handle viáticos vs. local expenses, how to prepare the company for electronic auditing that cross-references CFDI with returns in near real time.

Update frequency here is high: the SAT publishes the Resolución Miscelánea Fiscal (RMF) annually, changing limits, forms, and the CFDI catalog. Posts are reviewed and dated when that happens.
