What this means if you relocate to Bulgaria

The first thing that matters is tax residency: 183+ days in any 12-month period, or a permanent address with centre of vital interests in Bulgaria. The 183-day line is the headline trigger, but a home, family or business ties can make you resident sooner — so counting days alone is risky.

Once resident, Bulgaria taxes your worldwide income, so income earned abroad is in scope unless a treaty or special regime says otherwise. The top 10% rate only bites at the highest income band — an average earner pays less.

Foreign pensions and investments

Foreign pension: Taxed at the standard 10% flat rate (no dedicated pension regime); most treaties assign pension taxing rights to Bulgaria as residence country. Foreign capital gains and dividends: Capital gains taxed at 10% flat for residents; dividends (Bulgarian or foreign) subject to 5% final tax. These outcomes can be overridden by a double-tax treaty, which decides whether the source country or Bulgaria taxes each stream — a key reason retirees should map their specific income against the relevant treaty.

A US tax treaty with Bulgaria helps reassign taxing rights and reduce withholding, and US citizens lean on the Foreign Earned Income Exclusion and Foreign Tax Credit to avoid double income tax. With no totalization agreement, you can be exposed to social-security-type charges in both the US and Bulgaria. See our guides on FEIE vs the Foreign Tax Credit and totalization agreements.
