About NF-e tax events

Learn how to manage calculation events required by the Tax Reform for NF-e documents.

The NF-e solution for Compliance Network helps you comply with the tax compliance requirements for the Contribuição sobre Bens e Serviços (CBS) and Imposto sobre Bens e Serviços (IBS) tax calculation events. The solution also:

Receives inbound and outbound NF-e documents through Invoiceware and Smart DF-e
Generates event XML files according to Technical Note 2025.002
Digitally signs and transmits the XML files to the tax authority
Retrieves each response
Stores and displays the complete history of orders, related files, and tax authority responses

Tax calculation events are electronic records that provide transparency and control over operations that affect the new taxes: IBS and CBS. They represent specific moments in the invoice lifecycle, including:

Full payment
Presumed credit appropriation
Allocation for personal use
Spoilage, theft, or non-delivery

The solution transmits each event through a web service for the Secretaria da Fazenda Estadual (SEFAZ) authorization, ensuring traceability and compliance.

Note:

Sovos only sends tax calculation events for inbound and outbound NF-e documents stored in Compliance Network.
