🇧🇬 Tax residency in Bulgaria

Bulgaria counts you as a tax resident if you spend 183 days here. That's the main rule. But it's not the only rule. If you don't hit 183 days but your "centre of vital interests" is here, you're still on the hook. Think of it like this: where do your deepest personal and economic ties lie? It’s not just about where you sleep.

What pulls your centre of vital interests to Bulgaria? Owning property is a big one. Especially if you plan to stay. Having your spouse or minor children living here permanently does too. A registered business that you control or manage here? That's another strong indicator. Even if you're technically spending most of your time elsewhere, these factors can anchor your tax residency to Bulgaria. Don't assume you're safe just because you dip below the 183-day mark.

Once you're a tax resident, Bulgaria taxes your worldwide income. That means everything you earn, from freelance gigs in Thailand to dividends from a US stock portfolio, is potentially taxable here. The good news? The personal income tax rate is a flat 10%. It’s applied to most income types, including employment, self-employment, rent, and capital gains. For a digital nomad earning, say, €50,000 annually, that’s a €5,000 tax bill. It's refreshingly simple compared to progressive systems. However, social security contributions are a separate beast. They can add a significant chunk, especially if you're self-employed. Expect to pay around 27.8%† on a portion of your income, capped at a certain threshold. For that same €50,000 earner, this could add another €5,000-€7,000† depending on how your income is structured.

Bulgaria doesn't really have a special tax regime for digital nomads in the way some other countries do. There's no specific programme offering reduced rates or tax holidays just for remote workers. The 10% flat rate is the regime. It's low, yes, but it applies universally to residents. If you're earning significant income, especially from passive sources or dividends, you'll want to check double taxation treaties.

For US citizens, the US-Bulgaria tax treaty prevents you from being taxed twice on the same income. You'll generally pay tax in the country where you are resident, but the treaty provides mechanisms to claim credits for taxes paid in the other country. For UK residents, a similar treaty exists. The principle is usually that you pay tax where you have your permanent home or centre of vital interests. For German residents, the Germany-Bulgaria double taxation agreement works along the same lines. The key takeaway is that while Bulgaria taxes your worldwide income, these treaties ensure you don't end up paying the full tax amount in both countries. You'll likely get a credit for taxes paid in Bulgaria against your liability in your home country, or vice versa, depending on specific income types and treaty tie-breaker rules.

Hiring a local accountant is often worth the expense when your tax situation gets complicated. If you're earning income from multiple countries, have significant investments, or are unsure about how treaty provisions apply to your specific circumstances, an accountant can save you money and prevent costly mistakes. For a simple freelance income stream taxed at the flat 10%, you might be okay. But once you’re dealing with dividend income, capital gains across borders, or complex business structures, paying an accountant €50-€150 per month† quickly pays for itself by ensuring compliance and optimizing your tax liability.

You'll likely trigger tax residency in Bulgaria if you spend more than 183 days here or if your personal and economic ties are clearly based in the country.
