What Sefaz Amazonas does

Sefaz Amazonas (Secretaria de Estado da Fazenda do Amazonas) is the official state treasury and finance secretariat of the State of Amazonas, Brazil, operating as a government department under the Governo do Estado do Amazonas. It is the exclusive state-level authority for administering ICMS (the state tax on circulation of goods and inter-municipal/interstate transport and communication services), IPVA (vehicle property tax), and ITCMD (inheritance and donation tax), as well as for executing the state budget, managing the state treasury, distributing tax revenues to 62 municipalities via the SRT system, and conducting fiscal auditing and enforcement.

Its operational backbone is an integrated digital ecosystem comprising more than 20 named proprietary systems organized around four functional domains: (1) taxpayer management and registration (CAD-e/GCC); (2) revenue collection and fiscal action (GAE, GAF, GET); (3) treasury and budget execution (AFI, SIGO, SRT, SISCONV); and (4) electronic fiscal document processing (Nota Fiscal Amazonense for NF-e, NFC-e, BP-e, CT-e, MDF-e, NF3-e, NFF; DT-e for transport documents; GDD/GDDI for customs clearance). Supporting modules cover HR (GPE), contracts (SGC), strategic planning (SGE), document management (SIGED), and government procurement (Portal E-Compras). A citizen-facing innovation is Busca Preço Amazonas, a public price-transparency application that queries NFC-e electronic invoice data from the SEFAZ database in near real time (last 48 hours to 7 days).

SEFAZ Amazonas generates no commercial revenue. Services are provided free of direct charge to citizens, businesses, and municipalities; tax rates are set by state legislation. Distribution is delivered through a portfolio of 278 digital services via online portals, supplemented by call center (92-2121-1600), email ouvidoria, and in-person appointments. The entity operates within a federally coordinated fiscal IT framework, integrating with Receita Federal do Brasil (SPED, Simples Nacional, national electronic invoice standards) and CONFAZ/ASTAF (interstate ICMS harmonization), and serves three persona segments: Pessoa Jurídica (business taxpayers), Pessoa Física (individual citizens), and Órgãos Públicos (62 municipalities plus state agencies). Headquarters are at Av André Araújo 150, Aleixo, Manaus, Amazonas.
