The Estonian side of a UK business

When does an Estonian company help?

We work for UK businesses that use Estonia as a real place of operation, not only as a structure. That is usually the case when:

• your UK group has an Estonian subsidiary with its own staff, premises or customers,
• the company is registered for VAT in Estonia and files a return every month,
• you employ people in Estonia and need payroll under Estonian rules,
• decisions about the Estonian business are actually taken in Estonia.

In these cases you need books kept under Estonian law and filings made on Estonian deadlines. That is our work. The Estonian company exists because the business is there, so the accounting has to be right whatever the tax outcome.

When does it not help?

The position is different if you live in the UK, run the company from the UK and expect an Estonian OÜ (a private limited company) to lower your UK tax. In most cases it will not.

What do we say about UK law?

We state only the four points below about UK law. They come from legislation and from guidance by HMRC, the UK tax authority. Anything else is a question for your UK adviser.

• A company incorporated in the UK is UK tax resident.
• A company incorporated elsewhere is also UK tax resident if its central management and control is exercised in the UK. HMRC sets out its approach in Statement of Practice 1/90.
• If a company is resident in two states, a tie-breaker in the double tax treaty decides which one prevails. HMRC covers dual resident companies in its Company Taxation Manual at CTM34505.
• The UK has controlled foreign company rules in Part 9A of TIOPA 2010 (the Taxation (International and Other Provisions) Act 2010). They can attribute a foreign subsidiary's profits to a UK company.

Which questions do we leave to your UK adviser?

The questions below are for your UK adviser. We raise them, but we do not answer them.

• Where is central management and control actually exercised, and how would you show it?
• Could the controlled foreign company rules reach the profits of your Estonian company, and which exemptions might apply?
• How is a distribution from Estonia treated at your UK company, or in your own hands?
• Does your activity in the UK create a UK taxable presence for the Estonian company?

If the answer to one of them points against an Estonian company, we will say so.

Is your Estonian company a real operation?

1. Does the company have employees who work in Estonia?
2. Are its decisions actually taken in Estonia?
3. Does it have Estonian customers, suppliers or an Estonian VAT registration?
4. Would it exist whether or not it changed your UK tax bill?

If you can answer yes, you probably have a real Estonian operation, and the accounting is an obligation that needs to be done properly. If you are asking only because of the tax rate, we start with two questions of our own. Where would the company be managed, and what does your UK adviser say?

Which Estonian rates and deadlines apply?

• Corporate income tax: 0% on retained and reinvested profit, and 22% on distributions, charged as 22/78 of the net distribution.
• VAT: 24% since 1 July 2025. The registration threshold is 40,000 EUR, and the VAT return (KMD) is due by the 20th of the following month.
• Annual report: due by 30 June.
• Payroll: social tax of 33%, and unemployment insurance of 1.6% for the employee and 0.8% for the employer.

How we work with your UK accountant

Once you authorise it, we speak to your accountant directly. Together we agree the chart of accounts, the reporting format and the dates, so the Estonian figures reach your group accounts without rework. If your auditor asks for the ledger, supporting documents or reconciliations, we provide them in the agreed format and on the agreed dates. The regular work is monthly bookkeeping, and we file the annual report by 30 June.
