In Bulgaria, the requirement to register for value-added tax (VAT) depends on whether the business is established in Bulgaria and the nature of the taxable activities carried out.
For Bulgarian-established businesses, VAT registration is required once annual taxable turnover exceeds BGN 100,000 (approximately EUR 51,000) within a rolling 12-month period. This is the statutory domestic threshold under the Bulgarian Value Added Tax Act. Businesses below this threshold are not required to register unless they carry out activities that trigger mandatory registration.
There is no VAT registration threshold for nonresident businesses. VAT registration is generally required for foreign businesses from the first taxable supply, unless the reverse-charge mechanism fully applies.
Bulgarian businesses making cross-border B2C supplies of goods or services to customers in other EU member states must consider the EU-wide EUR 10,000 OSS threshold for total cross-border EU sales. Once this threshold is exceeded, VAT must be charged in the member state of consumption. The supplier may register locally in each member state or elect to use the EU One-Stop Shop (OSS) scheme.
Apart from the domestic BGN 100,000 threshold for Bulgarian-established entities, there are no general simplification thresholds. VAT registration is typically mandatory once the relevant taxable activity is undertaken, particularly for nonresident or cross-border business models.
