Foreign residents must declare all cross-border earnings in their Bulgarian return:

- Double Tax Treaties (DTTs): Bulgaria maintains an extensive network of bilateral Double Taxation Treaties. Taxpayers can claim foreign tax credits or exemptions for taxes already settled abroad, provided official tax certificates and certified translations are filed, Taxes – Accounting Services in Bulgaria
- Foreign Financial Accounts & Shares: Certain overseas financial assets, corporate shareholdings, and cross-border loans must be formally disclosed on the supplementary schedules of the annual tax return.
