Romania vs Estonia company formation (and Bulgaria): 2026 guide

Updated 14 September 2026 · 8 min read · The Start4 team

Romania vs Estonia company formation, with Bulgaria as the third candidate: the comparison most Europeans make before choosing where to register. The short answer is that the best country is the one where you actually live and run the business. Below you get the taxes side by side with real figures, what e-residency does and does not give you, and which jurisdiction fits each profile.

The short answer: it depends on where you live and where your clients are

There is no best EU country to open a company in the abstract. There is the right one for where you live, where your clients are and what you do with the profit. Comparing tax rates alone is how people end up with a company registered in one country and a tax bill in another.

In one sentence each: Romania is the cheapest to run day to day if you employ at least one person, with 1% on revenue for small companies and 16% on dividends. Estonia taxes nothing while profit stays in the company and is built for remote management, but e-residency is not residence. Bulgaria has the lowest headline rates in the EU, 10% on profit and 5% on dividends, and expects you to be there.

The rest of this guide puts the figures side by side, then looks at what each country asks in return, because that is where the real differences are.

Taxes compared: Romania, Estonia and Bulgaria in one table

The table uses 2026 figures for Romania and the current rules for Estonia and Bulgaria. Where a country's minimum share capital is symbolic we say so rather than quote a figure that moves with the exchange rate.

Two things the table cannot show: Romania's 1% comes with a condition, one full-time employee, and Estonia's 0% is a deferral, not an exemption. Both are explained below.

Romania: 1% micro-company with one employee, 16% otherwise

Romania's advantage is the micro-company regime: 1% on revenue up to €100,000 a year, provided the company has at least one full-time employee. Above the ceiling, or without the employee, you pay 16% on profit. Dividends are taxed at 16% from 2026, and personal income tax is a flat 10%. A consultant billing €80,000 a year through a micro-company pays €800 of company tax, before dividends.

Costs are low across the board: 500 lei of share capital, about €100, formation in 3–7 working days, a registered office at €130 a year after the first, accounting from €99 a month. VAT is 21% with an 11% reduced rate, and registration is compulsory only above 395,000 lei of revenue. Romania is in the EU, has a growing economy and labour costs still below the EU average, which matters if you hire.

The limits are real. The employee is a condition, not an option: without one the 1% disappears and you are at 16%. Accounting is monthly and mandatory from the first month, with filings that need an accountant, so a Romanian company is never a structure you put in a drawer. The full conditions are in our guide to Romanian micro-company tax in 2026, the yearly budget in the one on the cost of opening a company in Romania.

Estonia: 0% while profit stays in the company, and what e-residency really is

Estonia does not tax corporate profit as long as it stays in the company. Tax is due only when you distribute it: 22% in 2025, and the rate rises from 2026. Reinvest everything for five years and for five years you pay nothing on the company's profit. For a startup that lives on growth rather than dividends, that is the best regime of the three.

E-residency is what makes Estonia easy to run from anywhere: a digital identity that lets you sign, file and manage the company online. It is not a residence. It gives you no personal tax residence, no right to live in Estonia and, above all, no tax residence for the company. VAT is 24%, the highest of the three, and the minimum share capital is symbolic.

The catch is management. If you run the Estonian company from Italy, Germany or Spain, the country you sit in can claim it as its own tax resident, because the decisions are taken there. You end up owing corporate tax at home on a company that Estonia taxes at 0%, plus two accountants. E-residency does not protect you from this, and the Estonian programme itself says so.

Bulgaria: 10% and 5%, the lowest rates on paper

Bulgaria has the lowest headline taxes in the EU: 10% on profit and 5% on dividends. A company with €100,000 of profit that pays it all out leaves its owner €85,500 after both taxes. Against Romania's 16% and 16% under profit tax, or Estonia's 22% on distribution, the arithmetic is clear.

The price is presence. Bulgarian authorities expect the company to have substance in the country: an office, someone who decides, ideally the owner living there. Formation and banking go through Bulgarian-language documents and a notary, and remotely run structures are harder to keep than in Romania or Estonia. VAT is 20%, share capital is symbolic.

Bulgaria works well for someone who moves there or has a real operation there. For someone staying in Milan or Munich who wants a 10% company by post, it works badly, for the same reason Estonia does: the tax authority at home will not accept a company that exists only on paper in Sofia.

The criterion that beats every other: substance

Wherever you register the company, if the person who makes the decisions lives somewhere else, that country's tax authority treats the company as its own. The test is called effective management, and every EU state applies a version of it. The registered address is irrelevant; what matters is where the director sits when they sign, hire, negotiate and decide.

This is why comparing rates without substance is pointless. A 10% Bulgarian company managed from Italy becomes an Italian taxpayer at Italian rates, with penalties for the years it was not declared. The same applies to Estonia and the same to Romania. No jurisdiction on this list solves a tax problem for someone who does not move.

Substance means concrete things: the director lives in the country or spends most of the year there, decisions are taken there, there is an office, staff or at least an accountant and a bank account there, and the business has a reason to be there beyond the tax rate. Romania's employee condition, which looks like a constraint, is also the cheapest substance you can buy: a real person on a real contract.

Which country for which profile

Four cases we see most often:

• Freelancer or consultant who relocates: Romania or Bulgaria, and the answer is the country you will live in. Romania at 1% on revenue, 16% on dividends and 10% on personal income; Bulgaria at 10% and 5%. Both need you there.
• Startup reinvesting for years: Estonia. 0% until distribution is the best regime for growth, provided the founders, or at least the management, are in Estonia or the company has real substance there.
• E-commerce with a warehouse and staff: Romania. Labour costs, a domestic market inside the EU, the micro-company regime and EU VAT make the difference.
• Someone who stays in their own country: none of the three. Open the company where you live, or plan the move first.

If you are between Romania and Bulgaria, the deciding factors are usually language, the bank and how much you will pay yourself in dividends: Bulgaria wins on dividends, Romania on running costs, speed and remote formation.
