How to Update Your Estonian Company Details (2026 Guide)
Update company details Estonia is required whenever a company’s legal information changes.
If you need to update the official details of your Estonian company in 2026, the process is fully online through the Business Register. This guide explains how to update your company’s legal address, board members, contact person, shareholders, beneficial owners, and articles of association — step by step.
Keeping your Estonian company details accurate in the Business Register is essential for maintaining compliance, avoiding penalties and ensuring reliable communication with authorities. The Estonian Business Register help system (abiinfo.rik.ee) clearly states that company data must be updated as soon as changes occur.
This 2026 guide explains which details must be updated, when updates are required, and how to submit the changes online as an e-resident.
What company details must be updated?
Update company details Estonia is a mandatory process for every company, as all legal information must remain accurate in the Business Register. In 2026, all updates are submitted fully online, including changes to your legal address, board members, shareholders, beneficial owners, and articles of association.
This guide explains clearly which company details must be updated, when updates are required, and how to submit them correctly as an e-resident.
The Business Register lists the following items under “Juriidilise isiku andmete muutmine” (updating legal entity information):
Legal address
If your company changes its registered office address, you must update it immediately. This prevents delays in receiving official notices and procedural documents.
Contact person
This applies when company management is located outside Estonia. A licensed contact person must be appointed and added to the register.
Management board members
Adding or removing board members, or updating their residential address, requires a change application.
Shareholders and share capital
Share transfers, changes in ownership structure and adjustments to share capital must be reflected accurately.
Articles of association
Amendments to the articles, including activity changes or capital rules, must be submitted as updated documentation.
Beneficial owners (UBO)
The ultimate beneficial owner must be updated within the statutory deadline following a change.
According to the official help page “Juriidilise isiku andmete muutmine”, these updates must be submitted without delay.

When must you update company details?
Under Estonia’s Commercial Code, updates must be submitted immediately after changes occur. For remotely managed companies, timely updates are especially important, as the Business Register relies on this information to deliver official correspondence and maintain accurate public records.
Failure to update company details may result in:
- communication delays
- compliance notices
- difficulties during KYC or AML checks
- suspension of procedures
- possible penalties or compulsory dissolution in repeated cases
What you need before you start
To update company details, ensure you have the correct documentation prepared in advance:
- e-Residency digital ID card and PIN codes
- the new address details, board member data or amended articles
- contact person service agreement, if applicable
- legal address service agreement
- digitally signed confirmations where required
The Abiinfo guide confirms that supporting documents must be uploaded for certain types of changes.
If your company requires updated minutes of the meeting or a resolution to complete the application, we can prepare the necessary documentation in a compliant format and assist you with submitting it to the Business Register.

These resources explain in more detail how the legal address, contact person and company data updates work together in practice.
When do you need a contact person?
If all board members reside outside Estonia, appointing a licensed contact person is compulsory. The contact person ensures that official correspondence reaches the company correctly and that authorities have a reliable point of contact.
The Business Register will not approve an address change if the required contact person is missing. The practical details of this requirement are explained further in the contact person in Estonia guide for e-residents.
How a virtual office helps maintain compliance
A virtual office service typically includes:
- registered legal address in Estonia
- licensed contact person, when required
- mail handling and document forwarding
- basic compliance monitoring
- digital notifications about incoming official mail
This is the most efficient solution for managing an Estonian company remotely and keeping the company’s data correct in the Business Register.
Frequently asked questions
Do I need a notary?
Notary involvement is required only for shareholder-related actions that legally require notarisation. Standard updates such as address, contact person or board member data do not need a notary.
How long does the update take?
Most updates are processed within 1–3 working days. The exact time depends on the volume of applications and whether all documents have been submitted correctly.
Can one board member sign?
This is possible only if the articles of association allow individual representation. Otherwise, all board members must sign the change application.
What happens if I forget to update a change?
The company risks compliance reminders, delays with banks and service providers, or penalties if required corrections are not made in time. In repeated or serious cases, compulsory dissolution can be initiated.
Conclusion
Updating your Estonian company details is a straightforward digital process, provided all required documents are prepared in advance. Ensuring accuracy in the Business Register is essential for maintaining compliance, especially when operating remotely as an e-resident.
