Why SAF-T is more than just a file

What is SAF-T and why does it require special preparation?

SAF-T (Standard Audit File for Tax) is a standardized format for tax data that requires the information to be prepared in a specific structure and submitted to the NRA. Reporting is being introduced in phases and is expected to cover all businesses in Bulgaria by 2030. Preparing in time is key.

Какво е SAF-T и защо изисква специална подготовка

The main challenge is not the XML file itself, but:

  • preparing accurate data from various systems and modules;
  • ensuring compliance with the structure through mapping;
  • control and validation before submission;
  • error management and resubmission;
  • history and traceability of exports and versions.
