MC1182091: Dynamics 365 Finance - Implement 2026 tax changes in electronic invoicing for Brazil
We are announcing the ability to implement 2026 tax changes in electronic invoicing for Brazil in Dynamics 365 Finance. This feature will reach general availability on December 1, 2025.
How does this affect me?
This update includes enhancements to the Brazilian electronic invoicing functionality within the integration with the Brazilian Tax Authorities. It covers the required changes introduced by the tax reform that include adapting the XML generation logic to include new fields, implementing new validation rules, and a transition period during which old and new taxes coexist.
Microsoft released layout changes to the Brazilian electronic invoicing functionality in accordance with Technical Notes 2024.001 and 2024.002. The new E-Invoicing NF-e and NFS-e layouts updated to comply with new taxes and classifications are as follows:
New Fields
The NF-e XML schema updated to include new fields for CBS, IBS, and IS. This update includes:
- Fields to capture tax bases, rates, amounts, deferrals, exemptions, and presumed credits for each tax.
- Specific fields for federal (UF) and municipal IBS rates.
- Fields for selective tax amounts, especially targeting items harmful to health or the environment.
Group UB
A new data group in the NF-e, called UB, handles details for CBS, IBS, and IS. This group includes fields for:
- Calculation bases, rates, and tax values.
- Information about exemptions, deferrals, and reductions.
Totalization Fields
When you update the totalization section of the NF-e, the system correctly sums up CBS, IBS, and IS values.
What action do I need to take?
