Cyprus vs Bulgaria for founders: two low-tax EU routes compared

Bulgaria has the lowest headline corporate rate in the EU and one of the simplest systems: a flat 10% on company profit, a flat 5% withholding on dividends, a flat 10% on personal income. Cyprus charges more at company level, 15% from 2026, but layers reliefs on top that Bulgaria does not have: dividends free of defence contribution for non-dom residents and a 3% effective rate on qualifying IP profit. Which route leaves more in your pocket depends on what kind of profit you make and where you will live, and the whole calculation runs through three layers, company tax, dividend tax and personal tax. We work through all three below, with the actual figures on both sides.

How do Cyprus and Bulgaria tax company profits?

Bulgaria charges a flat 10% corporate tax on annual taxable profit, with the annual return filed between 1 March and 30 June of the following year and the tax due by 30 June. There are no reduced regimes and nothing to elect into. The 15% Pillar Two minimum only touches groups with €750m+ in consolidated revenue, so for a founder-owned company the 10% is simply the rate.

Cyprus charges 15% from tax year 2026, up from 12.5% for years through 2025. The increase came with the 2026 reform, which also cut the taxes on the owner's side of the chain; our reform guide covers the full package. So at company level Bulgaria wins by five points, and any comparison should start by saying so plainly. The question is what happens to the profit after the company has paid its tax.

Both countries sit inside the EU single market, and since Bulgaria adopted the euro on 1 January 2026, both run their books and bank accounts in the same currency. EU market access no longer separates them at all.

What does the owner actually keep from a dividend?

Bulgaria withholds 5% on dividends paid to individuals, at source and final, the same for every shareholder.

Cyprus treats the dividend differently depending on who receives it. A relocating founder who becomes Cyprus tax resident without a Cyprus domicile qualifies as a non-dom and pays no Special Defence Contribution on dividends for up to 17 years, since deemed domicile only arises after 17 of the preceding 20 years of residence. Dividends are also exempt from personal income tax for everyone. What remains is the GeSY health contribution at 2.65%, on income up to €180,000 a year, which the company withholds at source and which applies to non-doms too.

A Cyprus-domiciled shareholder pays SDC at 5% on dividends from 2026 profits, cut from 17%, with the old 17% still applying to pre-2026 profits distributed through the end of 2031.

Run the numbers for a relocating founder on €100,000 of trading profit earned in 2026, all distributed. In Bulgaria: €10,000 corporate tax, then 5% withheld on the €90,000 dividend, leaving €85,500. In Cyprus as a non-dom: €15,000 corporate tax, no SDC, then 2.65% GeSY on the €85,000 dividend, leaving €82,748. Bulgaria keeps about three cents more per euro of profit. The gap is real but small enough that IP treatment, language and where you actually want to live usually decide the choice.

Does Bulgaria have an IP Box?

No, and this is where the comparison swings hardest. Bulgaria's answer to IP income is the answer it gives all income: 10%, no paperwork. Cyprus runs an OECD-compliant IP Box that deducts 80% of qualifying profit from qualifying intangibles such as in-house developed software, so only 20% is taxed. At the 15% corporate rate that is an effective 3% from 2026 (2.5% under the 12.5% rate through 2025) where the full nexus fraction applies.

The nexus fraction is the condition to understand before you count on the 3%: the benefit scales with R&D you performed yourself or outsourced to unrelated parties, so development bought from a related company abroad dilutes it. The IP Box explained walks through what qualifies and how the fraction is computed.

Redo the example with €100,000 of fully qualifying IP profit. Bulgaria is unchanged: €85,500 in the founder's hands. Cyprus: €3,000 corporate tax, then GeSY on the €97,000 dividend, leaving €94,430 for a non-dom. That is a swing of almost nine points of profit in Cyprus's favour. A software founder whose profit is mostly in-house developed IP has a strong Cyprus case; one whose profit is ordinary trading income does not get this lever at all.

How is the founder's salary taxed?

Bulgaria taxes personal income at a flat 10%, with no bands. Cyprus uses progressive bands, from 2026: 0% up to €22,000, then 20% to €32,000, 25% to €42,000, 30% to €72,000 and 35% above €72,000.

For a founder paying themselves heavily through payroll, Bulgaria's flat 10% clearly beats Cyprus's upper bands. For the more common pattern, a modest salary inside the tax-free band plus dividends for the rest, the Cyprus 0% band up to €22,000 does real work and the difference shrinks to little. Social insurance applies to salary in both countries and follows each country's own rates and ceilings. Salary vs dividends in Cyprus works the Cyprus split through with figures.

What does the language of administration cost you?

It costs more than a rate table shows. Cyprus is a former British territory where English is the working language of business, law and accountancy. The Registrar, the banks, auditors and the tax portal operate in English, company documents are drafted in English, and the compliance calendar, bookkeeping, VAT at the standard 19% once registered, VIES for EU B2B sales, audited financial statements and the corporate return, runs in a language you already have.

Bulgaria's administration runs largely in Bulgarian, frequently in Cyrillic: Commercial Register filings, tax authority correspondence, accounting records. Plenty of foreign founders run Bulgarian companies, but unless you read Bulgarian, every interaction with the state passes through a local accountant, lawyer or translator. You pay for that layer every month, and you cannot check your own filings without it.

This is also where the two countries differ in how much of the work you can keep in your own hands. A Cyprus company's books, VAT and payroll can run in software you operate yourself. In Sumly the AI reads your invoices and receipts, does the double-entry bookkeeping and matches your bank transactions, and the VAT return assembles itself from the books ready for you to review and submit. If you are starting fresh, we form the company with a 100% approval guarantee, money back minus government fees already paid if it is not approved, and the bookkeeping starts the day you order.

Which founder does each country suit?

Bulgaria fits the founder who wants the lowest flat rates with no regimes to manage, and who either reads Bulgarian or is comfortable delegating the whole administrative relationship to a local firm. If your profit is ordinary trading income and you pay yourself substantially through salary, the 10-10-5 chain is compact and cheap.

Cyprus fits the founder who is relocating personally, taking dividends from a company they run day to day, and who wants a system they can read and operate themselves. The non-dom regime, the IP Box for in-house software and an English-language calendar all point the same way. Among our comparison guides, this one is the most direct trade: Bulgaria's lower flat rates administered through intermediaries against Cyprus's structured reliefs administered by you.

The deciding question sits above both tax systems: where will you actually live? The favourable outcomes above assume you are personally tax resident in the country whose chain you are counting, and the Cyprus route runs through the 60-day residency rule and non-dom status as much as through the company itself. Owning a company in one country while living in the other gives you a mix of both systems plus management-and-control questions in each, which is exactly the situation where an hour with an adviser on each side is worth the fee. Pick the country you want to live in first; the incorporation follows.

Questions founders actually ask

Frequently asked

Is Bulgaria's corporate tax really lower than Cyprus's?

Yes. Bulgaria charges a flat 10% on company profit, the lowest headline rate in the EU, while Cyprus charges 15% from 2026. But the company rate is only the first layer. Bulgaria then withholds 5% on the dividend, while a Cyprus non-dom resident pays no defence contribution on dividends at all, only the 2.65% GeSY health contribution. On plain trading profit Bulgaria's full chain still comes out slightly lighter; on qualifying IP profit, where the Cyprus IP Box cuts the effective corporate rate to 3%, Cyprus wins clearly.

How are dividends taxed in Bulgaria compared to Cyprus?

Bulgaria withholds a flat 5% on dividends paid to individuals, final and the same for everyone. In Cyprus the outcome depends on the shareholder: a non-dom resident pays no Special Defence Contribution for up to 17 years and only the 2.65% GeSY contribution, while a Cyprus-domiciled resident pays 5% SDC on dividends from 2026 profits, with a transitional 17% on pre-2026 profits distributed through 2031.

Does Bulgaria have an IP Box?

No. Bulgaria has no patent-box regime; all profit is taxed at the flat 10%. Cyprus runs an OECD-compliant IP Box that deducts 80% of qualifying profit from in-house developed IP, leaving an effective rate of 3% from 2026. For a software company whose profit mostly qualifies, that 3% beats Bulgaria's 10% before you even reach the dividend layer.

Can I run a Bulgarian company in English?

You can run the business in English, but the administration runs in Bulgarian: Commercial Register filings, tax authority correspondence and accounting records are in Bulgarian, often in Cyrillic, so a foreign founder works through a local accountant or translator for every official step. In Cyprus, company documents, banking, the tax portal and professional work all happen in English, and you can read every filing you sign.

Are both Cyprus and Bulgaria in the EU and the eurozone?

Yes. Both are EU member states, so EU VAT numbers, VIES reporting and intra-EU supplies work on the same legal foundations in each. Cyprus has used the euro since 2008, and Bulgaria adopted it on 1 January 2026, so both now invoice and keep books in euro.

Does Sumly advise on Bulgarian tax?

No. Sumly is built for Cyprus limited companies: Cyprus books, Cyprus VAT and VIES, Cyprus corporate returns. This article gives you Bulgaria's headline figures from official Bulgarian sources so you can compare, but structuring advice on the Bulgarian side is a job for a licensed Bulgarian adviser.
