Something has gone wrong with your Estonian company. Maybe you have not filed the annual report and there is a notice sitting in your inbox. Maybe the accountant you used to set everything up has disappeared or stopped responding. Maybe you registered the company two years ago, did not really use it, and now the Business Register is threatening to delete it. Maybe you are paying for accounting every month but have no idea if it is being done correctly. Or maybe you have simply decided you want to close the company and have no idea how. Whatever the situation, this guide covers the six most common problems Estonian OÜ owners face, what happens if you ignore them, and exactly what 1Office Estonia does to fix each one.

You received a penalty notice from the Estonian Business Register

If you have received a formal warning (hoiatus) or penalty notice from the Estonian Business Register (Äriregister), the most important thing to understand is that ignoring it makes the situation significantly worse. The Business Register began issuing penalty proceedings systematically in 2023 and has continued in 2024 and 2025, targeting companies that have not submitted their annual report, do not have a valid registered address, or are missing a required contact person.

What the notice actually means

A formal warning from the Business Register is the first step in a penalty enforcement process. The notice gives the company a deadline to correct the deficiency, typically 30 days. If the deficiency is not corrected, the Business Register issues a compulsory penalty (trahv). The initial penalty is €200. This amount increases with each subsequent notice. Penalties are subject to 22% income tax in the hands of the recipient, which increases the effective cost. All penalties and warnings are publicly visible on the company's record in the Business Register, which means banks, clients, and counterparties can see them.

When the Business Register can delete your company

Since 2023, Estonian law allows the Business Register to delete a company entirely if the company has no assets registered in Estonia, is not involved in any ongoing court or enforcement proceedings, and the Tax and Customs Board (EMTA) has given its consent. Deletion is not the same as dissolution: it is an administrative removal of the company from the register, without the formal liquidation process. If your company is deleted, it ceases to exist as a legal entity. Recovering a deleted company requires a court process that is expensive, time-consuming, and not guaranteed to succeed.

What to do if you have received a notice

1. 1

   Identify exactly what the notice requires

   The notice will specify which deficiency must be corrected: missing annual report, missing contact person, invalid registered address, or a combination. Read it carefully or forward it to 1Office Estonia and we will identify the required action immediately.

2. 2

   Contact 1Office Estonia before the deadline in the notice

   The most common deficiency is a missing annual report. 1Office Estonia can prepare and file your annual report as a standalone service, even if your existing accounting is elsewhere. We have done this for hundreds of companies in penalty proceedings and can move quickly when deadlines are tight.

3. 3

   Confirm your registered address and contact person are valid

   If your notice relates to a missing contact person or invalid address, these are fast to resolve. 1Office provides both services. A contact person is legally required for any OÜ where the majority of the board does not reside in Estonia. If your previous service provider has ceased operations or you have simply lost track of your address registration, 1Office can step in immediately.

Your annual report is late, missing, or has never been filed

The annual report (majandusaasta aruanne) is the single most commonly missed compliance obligation for foreign-owned Estonian companies. Every OÜ registered in the Estonian Commercial Register must file an annual report by 30 June each year, covering the preceding financial year. This obligation applies regardless of whether the company had any activity, revenue, employees, or bank transactions. A dormant company with zero activity still has a legal obligation to file a simplified annual report.

The consequences of a late annual report

Late filing is better than no filing

If your 30 June deadline has passed, filing late is significantly better than not filing at all. The penalty process targets companies that do not respond, not companies that file late. A late annual report, filed voluntarily before the Business Register escalates its enforcement action, typically stops the penalty process and prevents deletion proceedings from starting. Every week of delay after a warning is issued increases your exposure. The correct action is to contact 1Office Estonia and get the annual report filed as quickly as possible.

Multiple years of missing annual reports

Some companies approach 1Office with two, three, or more years of unfiled annual reports. This is more complex but entirely solvable. Each missing year requires a separate annual report, prepared and filed in sequence. The bookkeeping for each year must be reconstructed or verified before the reports can be prepared. 1Office Estonia has handled multi-year catch-up filings for foreign founders many times. The process takes longer and costs more than a single year, but it is always better to resolve it than to allow the company to be deleted.

Your accountant has disappeared, stopped responding, or you have no idea what has been filed

This is more common than most people expect. The Estonian e-Residency ecosystem has produced a large number of small accounting providers, many of whom lack the stability, capacity, or expertise to support international clients reliably over many years. Founders regularly contact 1Office Estonia after discovering that their accountant has stopped responding, closed their business, moved on, or was never properly maintaining the books in the first place.

What to check immediately

• !
  Check the e-Business Register for your company's annual reports. The Estonian Business Register is publicly accessible at ariregister.rik.ee. Search for your company and check whether annual reports have been filed for each year. If reports are missing, this is the first problem to address regardless of anything else.
• !
  Check your e-MTA account for outstanding declarations. Log into the Estonian Tax and Customs Board portal (emta.ee) with your e-Residency card or Smart-ID and check whether any tax declarations are overdue. Missing TSD or VAT declarations create separate penalty risk from the Business Register.
• !
  Check whether your contact person and legal address registrations are still valid. If your previous accounting provider also supplied your legal address and contact person, and they have ceased operations, these registrations may have lapsed. Check your company record in the Business Register.
• !
  Gather all financial documents you have. Bank statements, sales invoices, expense receipts, and any correspondence from your previous accountant. Even an incomplete set of records is a starting point. 1Office Estonia can reconstruct bookkeeping from bank statements and primary documents when full records are not available.

How switching to 1Office Estonia works

Switching accountants for an Estonian OÜ is a defined process. It does not require any notification to EMTA or the Business Register. What it requires is granting 1Office Estonia access rights in the e-Business Register and e-MTA, transferring the accounting records and primary documents, and agreeing on a start date. 1Office will conduct an initial compliance review to identify any outstanding obligations before beginning the ongoing accounting work. This review is included in the onboarding process.

You do not know if your Estonian company is compliant

A significant number of Estonian OÜ owners are paying for accounting services every month but have no clear picture of whether their compliance is actually in order. This is particularly common among e-residents who do not speak Estonian, who set up the company through an automated platform, or who have always assumed their service provider is handling everything correctly.

Signs that something may be wrong

• ?
  You cannot log into e-MTA and see your declarations. If you have an e-Residency card, you have the right to access your company's tax declarations directly in e-MTA. If you cannot see them or do not know how to check, this is a sign that you have no visibility into your compliance status.
• ?
  You have not signed any annual report in the last two years. Annual reports must be signed by the board member using a qualified electronic signature. If you have not been asked to sign an annual report, it either has not been prepared or it was prepared without your knowledge or proper authorisation.
• ?
  You have not received monthly or quarterly accounting summaries. A professional accountant should be providing you with regular updates on your company's financial position, filed declarations, and any upcoming obligations. Silence is not a sign that everything is fine.
• ?
  Your invoices have been going into a personal PayPal or Wise account rather than a company account. This is a common setup problem, particularly for companies formed through automated platforms. Business income should flow through a company business account. Mixing personal and business accounts creates accounting and tax problems that compound over time.

You want to close your Estonian company

Closing an Estonian OÜ is a formal legal process called dissolution (likvideerimine). It is not as simple as stopping trading and abandoning the company. An Estonian company that is no longer needed must be formally dissolved and deleted from the Business Register. Abandoning the company without dissolution leads to ongoing compliance obligations, penalty proceedings, and eventually forced deletion, which carries personal liability for board members and potential e-Residency revocation.

The voluntary dissolution process

Voluntary dissolution of an Estonian OÜ involves the following steps. The shareholders adopt a resolution to dissolve the company. A liquidator is appointed, who is typically the existing board member. The dissolution is announced in the official gazette (Ametlikud Teadaanded) and in the Business Register. A mandatory waiting period of at least four months follows the announcement, during which creditors can submit claims. If the company has assets, these are distributed to shareholders after all liabilities are settled. A final annual report covering the liquidation period is prepared and filed. The liquidator applies to the Business Register to delete the company from the register.

Prerequisites for dissolution: what must be done first

Before dissolution can proceed, all outstanding obligations must be resolved. This means all annual reports must be filed and up to date. Any outstanding taxes or declarations must be settled with EMTA. Any employees must be properly terminated. Any VAT registration must be deregistered. Any open contracts or ongoing obligations must be addressed. If any of these are missing, the Business Register and EMTA will not approve the deletion application.

The faster alternative: deletion vs dissolution

For companies with no assets and no outstanding tax liabilities, the Business Register may approve a simplified deletion without the full dissolution process. This is faster and cheaper than full dissolution but is only available if EMTA confirms there are no outstanding tax obligations and the company has no Estonian assets. For companies that have never traded or have minimal activity, this route is often the most practical. 1Office Estonia can advise on which route is appropriate for your specific situation.

You want to switch to a better accountant

Not every problem with an Estonian company is a crisis. Sometimes the situation is simply that your current provider is not good enough. Slow responses, unclear invoicing, no proactive communication about upcoming obligations, language barriers, or simply a feeling that your company deserves more professional handling are all legitimate reasons to switch. Switching accountants for an Estonian OÜ is straightforward when done correctly and there is no requirement to stay with a provider you are not happy with.
