Bulgaria 10% corporate tax: the honest picture beyond the headline

10% corporate tax and a flat 10% personal income tax. Bulgaria attracts with its 10% corporate tax, but you only get it if you actually move. Real costs, residency, banking and a fair comparison with the US LLC.

Bulgaria comes up over and over when someone searches for "European country with low taxes". The argument is always the same: 10% corporate tax, 10% personal income tax, inside the European Union, no movement restrictions. On paper it looks unbeatable. The reality, as always, has important nuances.

At Exentax we work with clients who incorporated companies in Sofia and tell us, two years later, why they are considering migrating to a US LLC. This guide summarizes what is worth knowing before making the decision.

Available company types

The most common structure for foreign entrepreneurs is the OOD (Дружество с ограничена отговорност), the equivalent of a limited liability company. There is also the EOOD (single-member version) and the AD (joint-stock company), the latter reserved for larger projects.

Minimum share capital: 2 BGN (just over 1 EUR) after the most recent reform. Incorporation takes 1-2 weeks. Approximate setup cost: EUR 500-1,500 depending on the firm.

Real taxation, beyond simplified headlines

The corporate income tax is a flat 10%. It is one of the lowest in the EU and applies to net accounting profit after tax adjustments.

Personal income tax on labor income and dividends is also 10% (specifically 5% on dividends), but only affects Bulgarian tax residents.

Here comes the first important nuance: the 10% only matters if you, as the owner, also become a Bulgarian tax resident. If you keep your tax residency in Spain or another EU country, dividends paid by the OOD are taxed in your country of residence according to the double tax treaty rules.

For a Spanish resident, this means:

The Spain-Bulgaria treaty caps withholding at source at 5%.
Dividends are added to the Spanish savings tax base: 19% up to EUR 6,000, 21% up to EUR 50,000, 23% up to EUR 200,000, 27% up to EUR 300,000, 28% above.
A foreign tax credit applies for the Bulgarian withholding, but the combined burden lands around 25-28%.

In other words, without moving your tax residency, the "10% Bulgaria" disappears.

Becoming a Bulgarian tax resident: what it means

To pay the real 10% you need to become a Bulgarian tax resident. This implies:

Living more than 183 days a year in the country, or having your center of vital interests there.
Local registration, rented or owned home, service contracts.
Properly leaving your former tax residency. If you are Spanish, this means giving up Spanish IRPF, going through "exit tax" on latent capital gains above certain thresholds, and adapting to the new framework.
Adapting to life in Bulgaria: language, healthcare, schooling, professional networks.

It is not a minor formality. Many people who hear "10%" do not realize that the 10% requires a real move.

Recurring costs and accounting duties

A Bulgarian OOD has a meaningful administrative burden compared to a US LLC:

Mandatory monthly bookkeeping by a local accountant: EUR 100-300 per month.
Monthly or quarterly VAT returns if you cross the threshold (BGN 166,000, around EUR 85,000).
Annual corporate income tax return.
Annual accounts filed with the commercial register.
External audit if you exceed certain thresholds. The Exentax file stays aligned: facts first, documents second, response after that.

Realistic annual floor: EUR 2,000 to 4,500 in fees and filings alone. Well above the ~USD 600 per year of a US LLC.

Banking: better than Hong Kong, worse than the US

Bulgarian banking works, but opening an account as a foreigner usually requires physical presence in Sofia, a rental contract, business activity evidence and, in many cases, a prior personal account. UniCredit Bulbank, DSK Bank, Postbank and Raiffeisenbank are the usual options.

Wise Business and Revolut Business also work, but as EMIs. For Stripe and other processors, a Bulgarian company with a BG IBAN is eligible, but the European fintech ecosystem is neither as broad nor as agile as the US one.

Bulgarian substance versus US operating flexibility

For the typical profile we serve at Exentax (freelance, digital agency, SaaS, content creator, ecommerce):

Effective taxation: a US LLC allows conditional US federal treatment for non-residents and profit distributions without additional US tax (<a href="/en/blog/llc-pass-through-with-real-tax-structure">pass-through</a>). The total bill depends only on your country of residence.
No need to relocate: the LLC can be operated from any country. Bulgaria is only optimal if you are willing to live there.
Annual cost: USD 500-800 vs EUR 2,000-4,500 in Bulgaria.
International reputation: a US LLC is perceived as neutral and professional in any market.

When does Bulgaria still make sense? When you actually want to move there, integrate into the local market and benefit from the cost of living, low labor costs and access to the European single market from inside. For operating profiles staying in their country of origin, it does not pay off.

Pitfalls and frequent mistakes

Trusting that the 10% applies without relocating: the most expensive mistake. You end up paying twice (Bulgaria and your country).
Underestimating mandatory accounting: many discover too late that they cannot run the OOD on their own.
Paying yourself a salary instead of dividends without understanding social security: Bulgarian labor costs are low, but not zero. A director's payroll involves specific contributions.
Forgetting effective control (POEM): if you make decisions from Spain, the Spanish tax authority may argue that the place of effective management is Spain and tax the company there.

Real risks

Tax inspections by the NRA (Bulgarian tax authority): rare, but when they happen they require detailed documentation in Bulgarian.
Penalties for incorrect bookkeeping: the system penalizes formal errors with significant fines. With Exentax, the deadline is tied to a responsible person, a record and a practical action.
EU regulatory changes: BEPS Pillar Two pressure and European tax harmonization may erode the 10% advantage in coming years.

Real scenarios where Bulgaria 10% corporate tax: the honest picture beyond the headline applies

Case 1: entrepreneur billing 80,000 EUR/year from Spain without relocating.

Bulgaria adds nothing. Without Bulgarian residency, profits are taxed in Spain at the applicable rate plus potential penalties. A US LLC is a simpler and more efficient alternative. Exentax gives the obligation a named owner, a due date and supporting evidence.

Case 2: European entrepreneur moving to Sofia with family.

Bulgaria does pay off. Personal residency with flat 10% income tax, Bulgarian company to operate within the EU with intra-EU invoicing, reasonable quality of life at low cost. Solid combination.

Case 3: agency with 5 employees, 3 of whom are in Bulgaria.

It makes sense to set up a Bulgarian subsidiary for local employees and leverage low labor costs. The main company can remain where the founder resides. Legitimate and efficient mixed structure.

FAQ on Bulgaria 10% corporate tax

Is 10% really the only tax burden?

No. The 10% is just corporate tax. If you take dividends you pay an extra 5%. If you draw a salary as director, Bulgarian social contributions and personal income tax apply. The realistic total load on the owner is between 14% and 22%.

Do I need to live in Bulgaria to keep the company?

No to keep it, yes for it to make tax sense. Without Bulgarian residency, your home tax authority can apply effective management and reclassify all profits as your own.

What is Bulgarian banking like for non-residents?

Complex and conservative. UniCredit Bulbank, DSK and Raiffeisen require in-person visits, signed contracts and activity justification. European EMIs (Wise, Revolut) are the more operational alternative.

Is Bulgaria in CRS?

Yes. It is an EU member and applies DAC. Bulgarian accounts are reported automatically to your country of residence, like any other European account.

When to choose Bulgaria over a US LLC?

When you will reside in Bulgaria, have a local team or sell mainly to the European market and need intra-EU VAT invoicing. Otherwise, a US LLC offers a better combination of cost and effective tax burden.

What EUR-BGN exchange rate applies to a Bulgarian company?

The Bulgarian lev is fixed to the euro via a currency board at 1.95583 BGN/EUR since 1997. No relevant FX risk for EUR operations. Bulgaria is in the euro adoption process expected in the short term.

Practical close on Bulgaria 10% corporate tax

Bulgaria with its 10% is a valid option if you actually want to move to Bulgaria. It is not a fiscal shortcut to keep your life in Spain, Mexico or Argentina. For that case, a US LLC delivers a better combination of taxation, operating costs and banking flexibility.

If Bulgaria is on the shortlist, Exentax compares the 10% headline with residence, payroll, banking, VAT, clients and annual maintenance before incorporation. <a href="/en/book">Book a strategic review</a> if you need to know whether Sofia is substance or just a low-rate distraction.

The final decision is not comparing headline rates but estimating the real combined burden with substance, banking and compliance costs. When that calculation is done well, Bulgaria can be excellent or totally unsuitable depending on your concrete profile.

A Bulgarian company should be selected because management, substance, reporting and banking make sense for the business, not because the headline rate looks low. The file must explain why Bulgaria fits the operating model.

Mercury: as a US account for an LLC, it must match residence, activity, ownership and documentation. In structures involving Panama, Hong Kong, the UAE or another jurisdiction, it does not replace local substance or make the structure opaque; it works only when the USD flow and banking file are coherent.

Payoneer operates through European entities (Payoneer Europe Ltd, Ireland) that are also in scope for CRS for clients resident in participating jurisdictions.

Compare Bulgaria only after banking and residence

A Bulgarian company can be efficient in the right facts, but low tax alone is not a strategy. Exentax compares it against a US LLC, banking access, owner residency, reporting duties and operational friction before recommending a structure.
