Estonian Company for UK Citizens: e-Residency and an EU Business After Brexit

Until the end of 2020 a UK company was an EU company, and it could sell to a customer in Lyon the same way it sold to one in Leeds. That is the gap British founders who want an EU company after Brexit are trying to close when they look at Estonia. Here is what an Estonian company gives back, what it means for your taxes in the UK, and how to register one.

What British Businesses Lost in January 2021, and How an Estonian Company Gives It Back

Three things changed after 1 January 2021. A UK company stopped being established in the EU for VAT purposes, so every sale into Europe now needs a registration or an intermediary it did not need before; we compare the two positions in Estonia or the UK for non-resident founders. Marketplaces and EU product-safety rules began asking British sellers for an importer and a responsible person based in the EU. And European clients, agencies and public buyers started to prefer signing with an EU company, a quiet post-Brexit shift that is often decisive.

An Estonian OÜ (osaühing, the Estonian private limited company) answers all three at once: a European company with an EU VAT number, euro invoices and the EU entity your marketplace or client asks for. You set it up and run it online with e-Residency, the Estonian government’s digital ID for foreigners, and for UK citizens and residents alike it is the most direct way to start a business in Europe from the UK. By mid-2024, 4,675 Britons held the e-Residency digital ID and 1,153 of them had registered a company, and in 2025 the e-Residency programme received 526 new applications from the UK, 41% more than the year before.

The pattern is consistent: a seller on Amazon.de who needs an EU company to hold the VAT registration and act as the importer, a sole trader in Bristol whose client in Rotterdam now wants an EU supplier, a London agency tired of explaining why its invoices come in pounds. None of them wants to leave Britain; all of them want the EU side of their business to work the way it did before 2021.

The Core Idea: Profit That Stays in the Company Is Not Taxed

A UK Ltd is taxed on its profit every year, whether you draw the money or leave it in the business. Estonia works the other way round. An Estonian company pays no corporate income tax while profit stays in the company, and tax is due only when profit is distributed: 22/78 of the net dividend, roughly 22% of the gross amount.

The simplest way to use this is also the usual one for UK business owners. You pay yourself neither a salary nor a dividend from the Estonian company while it grows, and you live on your UK income or on what your UK Ltd pays you. The Estonian company keeps every pound of profit at full value instead of after a 19–25% deduction, and the tax question only comes up on the day you decide to take the money out. One condition applies, and the next section is about it: the Estonian company has to be tax resident in Estonia, not in the UK.

Here is what that looks like for a British owner with £80,000 of annual profit (roughly €95,000), at current UK rates, with the whole profit either kept in the company or paid out as dividends. The dividend rows assume the dividend is the owner’s only income that year, which keeps the UK tax at its lowest.

Paid out in full, the two are close, and that is the honest version. The advantage is in the rows above. In the years you keep the profit in the company, the Estonian company keeps all of it, and over the years it takes to grow a business that gap is the difference between funding the next hire from profit and funding it from a loan.

How to Keep the 0%: Three Ways to Run an Estonian Company from Britain

HMRC does not look at where a company is registered. It looks at where the company is actually managed, a test called central management and control, and that is what decides whether an Estonian company owned by a UK resident pays UK tax. A company run from a desk in Manchester is, in HMRC’s eyes, a British company, whatever its registry says. The rule is strict but predictable, so it can be planned around. In practice British entrepreneurs run their Estonian companies in one of three ways.

1. You Run Everything from the UK

You live in Britain, make every decision in Britain and have no partner abroad. Then the Estonian company is UK tax resident as well, and HMRC charges corporation tax on its profit as it would on a Ltd, so the 0% on retained profit does not apply. The profit is not taxed twice. The Estonia–UK tax treaty decides which country taxes it, and the returns are filed in both.

Everything else still works. The company is an EU entity, it can hold an EU VAT registration, it is the EU-based business your marketplace or client wants to see, and you keep running it online from the UK. For many UK-based founders this is exactly the point. The goal was a company in Europe and access to its market, not a lower tax bill, and the Estonian company delivers it without a second office or a move.

2. The Company Is Genuinely Managed from the EU

You have a co-founder, a partner or a board member who lives in the EU and actually runs the company: pricing, hiring, contracts, the bank. Decisions are documented where they happen. Then the company is managed outside the UK, it is tax resident in Estonia, and profit that stays in it is not taxed.

The UK also has anti-avoidance rules for income that arises abroad to a company a UK resident owns, known as the transfer of assets abroad rules. They are aimed at structures set up to avoid tax, not at a genuine business with a genuine manager in the EU.

3. You Move to the EU: The Brexit Expat

Thousands of Britons have moved to Spain, Portugal, France or the Netherlands since 2016. Many kept their UK Ltd, and that is where the problem starts. The country they now live in sees a company managed from its territory and begins treating the Ltd as its own taxpayer, with its own corporate tax on retained profit.

For British expats an Estonian company run with e-Residency is a cleaner fit. It is already an EU company, it does not depend on a UK address, and it is run entirely online from wherever you live. Whether it keeps the 0% on retained profit comes down to the question you already know from the UK, where the company is managed, except that your new home country is now the one asking it. We have written separately about what that means for British residents of Spain, where the rules are the strictest of the four. In practice the question usually arrives as a letter from the local tax office asking where the UK Ltd is really run from, and the Estonian company is then less a tax decision than a tidy-up.

Whichever way you run it, the Estonia–UK double tax treaty applies. It is the treaty signed in 1994, and Brexit did not touch it. Dividends you receive while you are UK resident are taxed in the UK under the normal dividend rules, and Estonia does not withhold anything on top.

Who It Suits and Who Should Keep Their Ltd

How a UK Citizen Opens an Estonian Company: Five Steps

1. Apply for e-Residency. e-Residency for UK nationals works the same way as for anyone else: the application is online, the state fee is €150, and once approved you are an e-resident and collect the card at a pick-up point of your choice. Allow two to five weeks.
2. Choose a name and arrange an Estonian address. Every company needs a registered address in Estonia. A service provider supplies it, together with a licensed contact person who receives official correspondence, for a fixed annual fee.
3. Register the company online. You sign the application in the e-Business Register with your e-Residency card, pay the €265 state fee, and the registry usually confirms the company within one business day. The full procedure is on our company formation in Estonia page.
4. Open an account. Most British-owned Estonian companies bank with a payment institution such as Wise; see our guide to a Wise account for an Estonian company. An account at an Estonian bank is possible too, but the bank will want to see a connection to Estonia.
5. Set up VAT and accounting. Apply for an EU VAT number if you sell to EU businesses or consumers, and have accounting in place from day one. An Estonian company files one annual report; monthly returns are needed once it is VAT-registered or pays salaries.

The running costs of an Estonian company are the question most British founders ask next. Beyond the two state fees, budget for the registered address and contact person, usually bundled by one provider, and for monthly accounting, whose price depends on how many transactions the company has. There is no minimum share capital to tie up; we break down the figures in how much it costs to start a company in Estonia.
