Bulgaria is set to join other countries implementing SAF-T, the OECD-backed standard schema for the exchange of information between tax payers and authorities.
The regime will apply to resident and non-resident tax payers (with a Bulgarian VAT number).
It is planned to announce in 2024 the formats and phased launch schedule. This indicates a likely launch of 2025 for the largest taxpayers.
