There are two different ways to combine companies: mergers and acquisitions. An acquisition happens when one company buys most or all of another company's shares or assets to take control, while a merger combines two separate companies into a brand-new, single organisation. In this article, we will discuss mergers.
A merger is a common way to combine companies in Estonia. The acquired company's assets, contracts, rights and responsibilities transfer to the acquiring company. The acquired company then ceases to exist without going through a separate liquidation process.
The good news for e-residents is that most of the steps can be done without travelling to Estonia – much like setting up a company and running its day-to-day business.
This article explains the basics of mergers and how to merge companies in Estonia.
An e-resident is likely to encounter one of two common scenarios – merging two Estonian companies or a cross-border merger.
When two Estonian companies merge, for example, two private limited companies (OÜs), the goal is to bring the activities under a single roof or to simplify a group structure. In a cross-border merger example, you might decide to move business activity to Estonia.
Estonian law recognises several ways to merge companies
A cross-border merger is when an Estonian company and a company from a different country merge.
You cannot merge an Estonian company with a company from any foreign country
The other company must be a limited liability company established under the law of a European Economic Area (EEA) country. Also, the company's registered office, management board location or its main place of business must be in an EEA country.
Commercial associations (tulundusühistu) cannot take part in a cross-border merger
A cross-border merger is intended to move the business. A cross-border merger may not be possible if the company is already being closed down and its assets are being distributed to shareholders. It is also not allowed in certain situations involving reorganisation, bankruptcy or criminal proceedings.
If the company registered in Estonia participates as the company being acquired (i.e., the one moved across the border), the Estonian registrar issues a cross-border merger certificate to the corresponding authority of the destination country.
The registrar may refuse to issue the certificate for many reasons:
To identify the purpose of the merger, the registrar sends an inquiry to the Estonian Tax and Customs Board and may contact other country or local government authorities or other public-law legal persons.
Merging two Estonian companies takes around two to five months, provided the merger is straightforward and there are no legal or administrative issues.
The timeline includes preparing the merger agreement and related documents, approving the merger, meeting requirements that protect creditors and registering the merger with the e-Business Register.
A cross-border merger involving an Estonian company typically takes several months to complete. While the exact timeline depends on the countries involved, the corporate structure and any regulatory or creditor-related requirements, a straightforward merger within the EU generally takes around five to seven months.
The process involves preparing and disclosing merger documents, obtaining shareholder approval, meeting creditor and employee protection requirements, obtaining the necessary pre-merger confirmations and completing registrations in the relevant countries. Early legal planning can help identify potential delays and keep the process moving efficiently.

You will use several platforms and portals to carry out a merger. As an e-resident, you can log in with an e-resident digital ID. With the e-resident digital ID, you can identify yourself in an electronic environment and sign digitally.
You sign and file the registration application for the merger in the e-Business Register. The e-Business Register portal is also used for filing other Commercial Register applications and supporting documents. Management board members can upload documents, sign applications and follow the progress of the proceedings.
A notary must authenticate the merger agreement. Notarial services can be used either by video call with the e-Notary services or in person at the notary's office. Each notary can decide whether to use remote authentication, i.e., by video call. We strongly recommend checking with the notary's office before the transaction.
Notices that are required to be published by law are listed in the Official Journal.
You can find plenty of sample documents online. However, the documents needed differ from one merger to another and depend on a range of circumstances. Therefore, using generic templates is not particularly recommended.
