What Is SAF-T?

SAF-T is a standardised electronic format for accounting data, created by the OECD. It allows tax authorities to receive, audit, and analyse financial data more efficiently.

Who Must Report from 2026?

The first group of companies required to file SAF-T reports from 1 January 2026 includes large enterprises that meet specific financial thresholds.

Step 1: Are you a large enterprise?

You qualify as a large enterprise under the Accounting Act as of 31 December 2023 if you exceed at least two of the following:

• Total assets: more than BGN 38 million
• Net sales revenue: more than BGN 76 million
• Average number of employees: more than 250

Step 2: Do you meet the additional criteria?

To be included in the first wave of SAF-T reporting, large enterprises must also meet at least one of the following additional thresholds for 2023:

• Net sales revenue exceeds BGN 300 million, or
• Net payments made to the NRA (after refunds) for taxes and social contributions exceed BGN 3.5 million.

Only companies meeting both sets of criteria (large enterprise status and at least one additional condition) will be required to submit SAF-T files from 2026.

Timeline for SAF-T Implementation

The Bulgarian NRA has provided a detailed roll-out plan for SAF-T obligations, extending through 2030.

Next Steps for Bulgarian Businesses

• Review their 2023 financials to determine whether they fall within the first wave of SAF-T obligations.
