US Expats in Bulgaria
~2,000 US citizens Americans live in Bulgaria. Here's what you need to know about managing your finances, staying compliant, and making the most of the US-Bulgaria tax treaty.
The US-Bulgaria relationship is anchored by a tax treaty and a totalization agreement that prevents double Social Security taxation. American residents in Bulgaria typically face an effective tax rate of 10%, with Bulgarian Lev (BGN) as the local currency. The largest US expat communities are concentrated in Sofia, Plovdiv, Varna and Burgas.
Beyond US obligations like Form 1040, FBAR, and Form 8938, US persons in Bulgaria must navigate 1 country-specific filing (detailed below) alongside the PFIC rules that affect most local mutual funds. The keys to staying compliant: track every BGN account against the $10,000 FBAR threshold, avoid local pooled investment products unless they qualify as QEFs, and reconcile foreign tax credits against the IRC §901 rules.
