Who Needs to File?
In Bulgaria, tax residents must file an annual tax return on their worldwide income. Non-residents are only required to file if they have earned income from Bulgarian sources.
Most employees with only employment income from a Bulgarian employer are not required to file if their employer conducts an annual reconciliation.
However, employees with additional income sources or income from foreign employers must file. All self-employed individuals, including freelancers and sole proprietors, are required to submit an annual tax return.
Types of Income to Declare
- Employment income (wages, salaries, bonuses).
- Rental income. Self-employment income.
- Capital gains (with some exemptions). If you’ve earned income from cryptocurrency transactions, these may also be subject to taxation.

- Loans provided or received—if they exceed specific thresholds, they must be declared.
