The Tax Administration Service (Spanish: Servicio de Administración Tributaria, SAT) is the revenue service of the Mexican federal government. The government agency is a deconcentrated bureau of the Secretariat of Finance and Public Credit, Mexico's cabinet-level finance ministry, and is under the immediate direction of the Chief of the Tax Administration Service. The SAT is responsible for collecting taxes, as well as applying fiscal and customs law, with the purpose of funding public spending in a proportional and equitable manner. Additionally, it is the bureau's responsibility to generate and collect information necessary for the formation and evaluation of fiscal policy. From Wikipedia
