What Is the Estonian e-Business Register and What Can You Actually Do With It?
The Estonian e-Business Register (e-äriregister) is the government’s official online company registry and filing portal — the single place where an Estonian company legally comes into existence, keeps its records, and stays compliant. Run by the Centre of Registers and Information Systems (RIK) under the Ministry of Justice, it lets you register an OÜ from your laptop in about a day, file your annual report, change directors or your address, and look up the public data of any Estonian company for free. What it is not is a bank or a tax office — those are separate systems. This guide walks through exactly what you can, and can’t, do with it as a founder or e-resident.
The short answer
The e-Business Register is Estonia’s official online company registry, operated by RIK under the Ministry of Justice; the public search side is at ariregister.rik.ee and the filing side is the Company Registration Portal at ettevotjaportaal.rik.ee.
You can register an OÜ (private limited company) fully online for a €265 state fee, usually reviewed within one business day.
Minimum share capital is €0.01 per shareholder — the old €2,500 minimum was dropped in February 2023.
Every Estonian company must file an annual report (majandusaasta aruanne) within 6 months of its financial year-end — that means 30 June 2026 for a calendar-year company.
Anyone can look up any Estonian company’s owners, board, share capital, and annual reports for free, with no login.
It does not handle banking or tax: VAT and taxes go through EMTA (the Tax and Customs Board), and a bank or EMI account is a separate step.
What exactly is the Estonian e-Business Register?
The e-Business Register (e-äriregister) is the official state registry of every company, non-profit, and foundation in Estonia — and the online portal you use to file with it. It is run by the Centre of Registers and Information Systems, known by its Estonian initials RIK, which sits under the Ministry of Justice. Think of it as Estonia’s Companies House, except almost everything happens online, in English, and without a single sheet of paper. Every OÜ, AS, and MTÜ in the country has a record here, and that record is what makes your company a real legal entity. Put simply: if your company is not in the register, it does not legally exist.
In practice the register has two front doors, and knowing which is which saves a lot of confusion. The public search side lives at ariregister.rik.ee — this is where anyone can look up a company for free, no account required, in Estonian, English, or Russian. The filing side is the Company Registration Portal (ettevõtjaportaal) at ettevotjaportaal.rik.ee, where you log in with a digital ID to actually register a company, submit changes, and file reports. Same register, two entrances: one for reading, one for doing. When people say the e-Business Register, they usually mean both together.
The register holds the full legal profile of each company: its registry code (registrikood), legal form, registered address, board members, shareholders, share capital, articles of association, beneficial owners, and every annual report it has ever filed. All of this is structured, machine-readable public data, which is a big part of why Estonia’s business environment feels so transparent. When you register or change anything, you are editing this authoritative record directly — there is no paper filing sitting in a drawer somewhere waiting to be processed. The register is the source of truth, and the change takes effect the moment the registrar approves it.
What can you actually do with it as a founder?
As a founder or e-resident, the e-Business Register is where you handle almost every official interaction with your company’s legal existence — from birth to closure. The table below maps the concrete tasks you will actually reach for, whether the register is the right place to do them, and what you need to get each one done. Everything marked yes can be done online, on your own, without setting foot in Estonia. Read it once and you will have a mental model of the whole system.
Task | Can you do it in the e-Business Register? | What you need |
|---|---|---|
Register a new OÜ | Yes — fully online | e-Residency (or Estonian ID), a legal address + contact person, €265 state fee |
Reserve a company name | Yes (optional) | Login + €150 fee; held up to 6 months |
File the annual report | Yes — free | Login, board-approved financials, submit within 6 months of year-end |
Change board members | Yes | Login, the new member’s consent, digital signatures |
Amend the articles of association | Yes | Login, a shareholders’ resolution, a state fee |
Change the registered address | Yes — usually free | Login and the new Estonian address |
Add or transfer shareholders | Yes | Login; larger share transactions may need a notarised transfer |
Look up any company’s public data | Yes — free, no login | Just the company name or registry code |
Get your registry code (registrikood) | Yes — assigned automatically | Complete the registration |
Register for VAT | Application can start here, EMTA decides | Cross the €40,000 threshold or register voluntarily |
Close / liquidate the company | Yes — you start it here | A liquidation resolution; the process takes several months |
Open a bank account | No | A bank or EMI (Wise, Revolut Business, LHV, etc.) |
File and pay taxes | No | EMTA’s e-MTA portal |
How do you register an OÜ online?
You register an OÜ directly in the Company Registration Portal, and for a straightforward company it is genuinely a one-sitting job. You log in with your e-Residency digital ID (or an Estonian ID-card, Mobile-ID, or Smart-ID), enter the company name, address, board, and shareholders, pay the €265 state fee, and digitally sign the application. The registrar reviews electronic applications under the expedited procedure and usually responds within one business day. Minimum share capital is just €0.01 per shareholder, so you are not locking up thousands of euros to get started. You do still need an Estonian legal address and a contact person, which non-residents typically buy as an annual service.
Log in to the Company Registration Portal with e-Residency, Mobile-ID, Smart-ID, or an Estonian ID-card.
Check your chosen name and enter the company details, board, and shareholders.
Add your Estonian legal address and contact person.
Pay the €265 state fee and sign the application with your digital ID.
Wait for the registrar’s decision — usually within one business day.
Can you reserve a company name first?
Yes, you can reserve a business name in the register before you incorporate, but most founders skip it. A name reservation costs €150 and holds your chosen name exclusively for up to six months, which is useful if you are building a brand before you are ready to file. The catch is that it is optional and not cheap relative to the €265 formation fee — if you plan to register soon anyway, you can simply enter your name during formation and the system checks availability at that moment. Reserve only if you genuinely need to lock a name in advance, for example while you sort out design, funding, or a domain.
How do you file the annual report (majandusaasta aruanne)?
Every Estonian company files its annual report (majandusaasta aruanne) through the e-Business Register, and it is the single compliance task most founders underestimate. The report is due within six months of the end of your financial year, so a company on the standard calendar year must file by 30 June 2026 for the 2025 financial year. You prepare the financials, the board approves them, and you submit the report in the portal — filing itself is free. Miss it and the consequences are real: fines of up to €3,200, and if you are more than three months late the registrar can begin deleting your company from the register. Even a dormant company with zero revenue and no transactions still has to file.
Can you change directors, shareholders, and the articles?
Yes — board changes, address changes, shareholder changes, and amendments to the articles of association all go through the register online. Swapping or adding a board member needs that person’s consent and their digital signature on the application. Changing your registered address is usually quick and often free. Amending the articles of association requires a shareholders’ resolution and a small state fee. Transferring or adding shareholders can be done in the portal for many companies, though larger or more complex share transactions may still require a notarised transaction. The point is that your company’s legal details are never frozen — you keep them current yourself, in minutes, from anywhere.
Where do you find your registry code?
Your registry code (registrikood) is the unique eight-digit number assigned to your company automatically the moment it is entered in the register — you do not apply for it separately. It is the number you will put on invoices, contracts, your VAT application, and your bank onboarding forms. You can always find it, and everyone else’s, on the public search at ariregister.rik.ee. It is the permanent identifier that follows your company for its entire life, from the first invoice to the day it is deleted, so it is worth saving somewhere handy on day one.
Can you close or liquidate the company here?
Yes, you start and run a company closure through the register, but this is the one task that is deliberately not a single click. To wind down voluntarily you pass a liquidation resolution, appoint a liquidator, notify creditors, and only then apply for deletion from the register — a process that runs several months because of a mandatory creditor-notice period. There is a simpler deletion route in limited cases, but for most active companies liquidation is the honest path. The register is where every step is filed and where your company’s public status changes from active, to in liquidation, to deleted. Do not just walk away and stop filing — an abandoned company still racks up annual-report obligations and fines.
How do you look up any Estonian company for due diligence?
One of the most useful things the e-Business Register does has nothing to do with your own company: it lets you vet anyone else’s. The public search at ariregister.rik.ee is free, needs no login for the basics, and works in English — so before you sign with a supplier, partner, contractor, or client, you can check whether they are a real, active company and who actually stands behind them. This level of open transparency is genuinely rare among registries, and it is one of Estonia’s real advantages. It takes about thirty seconds and can save you from a lot of trouble.
Whether the company is active, in liquidation, or deleted.
Its registry code, legal form, and registered address.
The board members and shareholders.
The declared beneficial owners — the real people behind it.
Share capital and the articles of association.
Every annual report it has filed, with the actual financial figures.
For deeper checks you can buy detailed paid reports or download the full open dataset in bulk for free, but for everyday due diligence the free search is usually enough. If a prospective partner is not in the register, has filed no annual reports, or hides behind a messy ownership trail, that tells you something important before any money changes hands. Used well, the register is as much a research tool as a filing system.
Your company legally lives inside the e-Business Register — it is where you are born as a business, where you stay compliant, and where the whole world can check, for free, that you are real.
What does the e-Business Register NOT do?
The e-Business Register handles your company’s legal existence — not its money and not its taxes. It will not open a bank account for you, and it is not the tax office. Banking is a separate step: traditional Estonian banks like LHV, Swedbank, and SEB often decline pure non-residents without a local link, so most e-residents use a fintech or EMI account such as Wise, Payoneer, or Revolut Business (LHV also runs an e-resident-friendly path). Tax lives with the Estonian Tax and Customs Board (EMTA): VAT registration, VAT and payroll returns, and paying what you owe all happen in EMTA’s e-MTA portal, not in the e-Business Register. Mixing these two up is the single most common beginner confusion.
What you need to do | Where it actually happens | Who runs it |
|---|---|---|
Register your company, file annual reports, change company details | e-Business Register (ariregister.rik.ee / ettevotjaportaal.rik.ee) | RIK, Ministry of Justice |
Register for VAT, file VAT and payroll returns, pay taxes | e-MTA portal | EMTA (Tax and Customs Board) |
Hold money, get an IBAN, send and receive payments | Your business bank or EMI | LHV, Wise, Revolut Business, etc. |
It is also worth being clear on the taxes themselves, because 0% tax is a myth people repeat about Estonia. Estonia charges 22% corporate income tax on distributed profit (calculated as 22/78 of the net distribution) and 0% on profit you retain or reinvest — the perk is deferral, not exemption. VAT is 24% since 1 July 2025, and it kicks in once your taxable turnover crosses €40,000 (or you register voluntarily). Personal income tax is 22% in 2026, and remember that e-Residency is not tax residency — you still owe personal tax where you actually live. All of that is administered by EMTA, not by the register.
How do you log in and sign?
To do anything more than look up a company, you need a digital identity that Estonia recognises and can use to sign documents electronically. For non-residents, that is e-Residency — a government-issued digital ID that lets you log in and legally sign in the register from anywhere in the world. Estonians and existing residents use their ID-card, Mobile-ID, or Smart-ID instead. Without one of these you can still read the register freely, but you cannot file anything, because every submission has to carry a qualified digital signature. Getting the e-Residency card is therefore the practical first step before the register becomes fully useful to you.
e-Residency digital ID — the usual route for non-residents.
Estonian ID-card — for residents and citizens.
Mobile-ID — sign with your Estonian mobile SIM.
Smart-ID — a widely used app-based option.
What does it cost to use the e-Business Register?
Reading the register is free; filing carries small, predictable state fees. Registering an OÜ online costs €265, a name reservation is €150, and filing your annual report is free. Most routine changes — updating an address or minor board details — are free or cost very little, while amending the articles of association carries a state fee. There are no subscription costs and no hidden charges from RIK itself. The bigger recurring costs of running an Estonian company — the legal address and contact person, plus accounting — sit outside the register, so budget for those separately.
Action in the e-Business Register | Typical 2026 cost |
|---|---|
Register an OÜ online (expedited) | €265 state fee |
Register via a notary | €265 + notary fees (usually €150–300) |
Reserve a company name | €150 |
File the annual report | €0 (free) |
Change address or minor board details | Often €0 |
Amend the articles of association | State fee applies (check the current rate) |
Look up a company / download open data | €0 (free) |
Frequently asked questions
Is the Estonian e-Business Register free to use?
Looking things up is completely free. Anyone can search any Estonian company at ariregister.rik.ee with no account and no fee, and you can even download the full open dataset for free. Filing, however, carries state fees — for example €265 to register an OÜ and €150 to reserve a name — while submitting your annual report is free.
Do I need e-Residency to use the e-Business Register?
You need it to file, not to read. Anyone can search the public register without any ID at all. But to register a company, sign applications, or submit reports, you need a digital identity Estonia accepts — e-Residency for non-residents, or an ID-card, Mobile-ID, or Smart-ID for residents.
What is the difference between ariregister.rik.ee and ettevotjaportaal.rik.ee?
They are two sides of the same register. ariregister.rik.ee is the public search — for reading company data with no login. ettevotjaportaal.rik.ee is the Company Registration Portal — where you log in to register companies, file reports, and make changes. In short: reading versus doing.
Can I file my taxes in the e-Business Register?
No. The e-Business Register handles company-law filings, not tax. VAT registration, VAT and payroll returns, and tax payments all go through EMTA, the Estonian Tax and Customs Board, in its e-MTA portal. The two systems are completely separate, even though a VAT application can technically be started from the register.
How much does it cost to register an OÜ through the e-Business Register?
The state fee is €265 for an expedited online registration, usually decided within one business day. Registering through a notary instead adds notary fees on top. Non-residents should also budget for e-Residency (about €100–150 one-off) and an annual legal-address and contact-person service, plus accounting.
Can I see who owns an Estonian company?
Yes. Every Estonian company must declare its beneficial owners — the real people behind it — and that declaration, along with the board and shareholders, is publicly visible on the company’s record at ariregister.rik.ee, for free. It is one of the fastest due-diligence checks you can run on any Estonian business.
What happens if I do not file my annual report?
You risk fines of up to €3,200, and the registrar can start compulsory deletion of your company if the report is more than three months overdue. The report is due within six months of your financial year-end, and even dormant companies with no revenue must file. It is the deadline founders forget most often, so put it in your calendar.
Can I close my company through the e-Business Register?
Yes, but it is not instant. Voluntary liquidation is filed through the register and typically takes several months because of a mandatory creditor-notice period. You pass a liquidation resolution, appoint a liquidator, notify creditors, and then apply for deletion once the process is complete. Simply abandoning the company is not a valid exit — the obligations keep piling up.
