SAF-T
About SAF-T
The Standard Audit File for Tax ("SAF-T") is a structured electronic format for the submission of the detailed accounting information of a business to the revenue authorities in a standardized and machine-readable way. Bulgaria will introduce mandatory SAF-T reporting in several waves starting from 2026.
What is the current status of the SAF-T implementation in Bulgaria?
On 25 July 2025, the National Revenue Agency (NRA) published the final version of the Bulgarian SAF-T schema, together with the required taxonomies and reporting guidelines. Taxpayers included in the first reporting wave are expected to be invited shortly to participate in pilot testing of SAF-T submissions. The first mandatory SAF-T reports are scheduled to be filed starting from the beginning of 2026.
Which businesses will be required to submit SAF-T reports?
SAF-T reporting will become mandatory for businesses in several waves:
- from 2026 for large enterprises with annual net revenue exceeding BGN 300 m. / EUR 153 m. or annual net tax and social security liabilities exceeding BGN 3.5 m. / EUR 1.8 m.;
- from 2027 for large, medium and small enterprises with annual net revenue exceeding BGN 300 m. / EUR 153 m. or annual net tax and social security liabilities exceeding BGN 3.5 m. / EUR 1.8 m.;
- from 2028 for large, medium and small enterprises with annual net revenue exceeding BGN 15 m. / EUR 7.7 m. or annual net tax and social security liabilities exceeding BGN 1.5 m. / EUR 0.8 m.;
- from 2029 for all large, medium and small enterprises;
- from 2030 for all VAT-registered enterprises.
The criteria for the category of enterprise under the Accountancy Act, annual net revenue and annual net tax and social security liabilities are assessed for two years in the past (i.e., reporting obligation will arise for 2026 if the criteria were met by the enterprise as at the end of 2023).
What will have to be reported with SAF-T?
SAF-T reports will cover detailed business and accounting information including:
- identification data for the taxpayer, including related parties and ultimate owners;
- chart of accounts and all accounting entries;
- all purchase and sales invoices, including all suppliers and customers;
- all incoming and outgoing payments;
- all assets, inventory, and related transactions;
- business nomenclatures and tax codes.
In total, several hundred separate mandatory data points will have to be reported with SAF-T (out of close to 1,000 data points in total).
How often will SAF-T reports have to be submitted?
SAF-T reports will have to be submitted on a monthly basis by the end of the following month. An annual SAF-T report covering only assets and asset transactions will have to be submitted by the deadline for the annual corporate tax return (30 June following the reporting year). A SAF-T report including information about inventory and inventory movements will have to be submitted upon request by the Bulgarian revenue authorities.
For each wave, the first 6 monthly SAF-T reports can be freely corrected by the deadline for submission of the seventh monthly SAF-T report.
