Dynamics 365 Finance - Use regulatory update of the Audit File Financial – XAF 4 for Netherlands from 2026

We are announcing the ability to use regulatory update of the Audit File Financial - XAF 4 for Netherlands from 2026 in Dynamics 365 Finance. This feature will reach general availability on December 31, 2025.

How does this affect me?
The Dutch Tax Administration (Belastingdienst) has introduced XML Auditfile Financieel (XAF) 4.0 as the new mandatory standard for digital financial audit files, replacing the outdated XAF 3.2 (2014). This feature ensures that Dynamics 365 Finance customers can generate XAF files in the new XAF 4.0 structure, fully compliant with the 2025 Dutch audit requirements.

XAF 4.0 includes the following improvements to the digital audit schema:

• Reduces data elements from ~250 to ~90
• Ensures alignment with Referentie Grootboek Schema (RGS)
• Improves consistency, quality and machine readability
• Designed for future harmonized EU digital tax frameworks (ViDA / SAF T)

This feature delivers Dynamics 365 Finance support for generating XAF 4.0 compliant audit files by enabling the following capabilities:

• New Electronic Reporting (ER) format for XAF 4.0
• Updated data model aligned with XAF 4.0
• Deprecation of XAF 3.2 format outputs
• Mapping improvements for general ledger, subledger, and master data
• Enhanced XML generation compliant with XAF 4.0
