Rio Grande do Sul companies must complete tax registration by September 30

All companies contributing to the ICMS tax in Rio Grande do Sul must complete their annual data update with the State Revenue Service (Receita Estadual) by September 30. The mandatory process applies to approximately 249,400 businesses registered in the CGC/TE until the end of 2025.

As of mid-August, only 14.7% of eligible companies had finalized the procedure. The update is conducted entirely online through the official State Revenue portal. The registration process verifies whether a business is actively operating, validates registration data such as addresses and corporate information, and updates the Electronic Tax Domicile (DTE) with current contact details for legal representatives.

Failure to comply by the deadline will result in the suspension of the state registration, which can prevent the issuance of invoices and the circulation of goods. Additionally, businesses must ensure a registered accountant is linked to their fiscal records in accordance with Decree 58.777/26, as registrations without a designated professional are also subject to suspension.
