Estonian OÜ Annual Report 2026: Complete Filing Guide

Estonian OÜ Annual Report: Everything You Need to Know

Every Estonian OÜ (private limited company) must file an annual report with the Estonian Business Registry. This is one of the most important legal obligations for e-Residents running Estonian companies.

Missing the deadline or filing an incomplete report can lead to fines, management board liability, and in severe cases, compulsory dissolution of your company. This guide explains exactly what you need to do in 2026.

What Is the Annual Report?

The annual report (Estonian: majandusaasta aruanne) is a formal financial statement that every Estonian company must submit once per year. It documents your company's financial health and business activities during the past financial year.

The annual report is:

• Publicly accessible via the e-Business Register at company.ee
• Required regardless of turnover (even €0 revenue companies must file)
• Subject to EMTA cross-checking for tax compliance
• A legal requirement under the Commercial Code § 183 and Accounting Act § 25

Deadlines

The annual report must be submitted within 6 months of your financial year end.

Most Estonian OÜs use a December 31 financial year end, meaning:

If your deadline falls on a weekend or public holiday, it moves to the next business day.

Who Qualifies as a Micro-Entity?

Estonian companies that meet at least two of the following three criteria qualify for simplified micro-entity reporting:

Micro-entities can use a significantly simplified report format with fewer mandatory notes and no cash flow statement requirement. Most e-Resident OÜs qualify as micro-entities.

What Must the Annual Report Include?

For Micro-Entities (Most e-Resident OÜs)

1. Balance sheet (abbreviated format) — assets and liabilities
2. Income statement — revenue, expenses, profit or loss
3. Notes (abbreviated) — accounting policies, related party disclosures
4. Management report — brief narrative about the year's activities (required for all companies)

For Small and Medium Entities

1. Balance sheet (full format)
2. Income statement
3. Cash flow statement (indirect method)
4. Statement of changes in equity
5. Notes (full)
6. Management report

Auditor's Report

An independent audit is required if your company exceeds two of these thresholds for two consecutive years:

Most e-Resident micro-OÜs do not require an audit.

How to Submit the Annual Report

Step 1: Prepare Financial Statements

Work with your accountant (or use accounting software like Merit Aktiva, Directo, or QuickBooks) to prepare:

• The balance sheet as of your financial year end
• The income statement for the full financial year

Step 2: Access e-Business Register

Log in to company.ee using your e-Residency digital ID (DigiID) or mobile ID.

Step 3: Start the Annual Report Wizard

Navigate to your company → Annual reports → Submit annual report

The wizard will guide you through:

• Selecting the report format (micro, small, or full)
• Entering balance sheet figures
• Entering income statement figures
• Adding required notes
• Writing a management report

Step 4: Digital Signing

The annual report must be digitally signed by all management board members. If you have multiple board members, each must sign with their own digital signature.

Step 5: Submit

Once signed, click Submit to Business Registry. You will receive a confirmation email.

Management Report: What to Write

The management report (Estonian: tegevusaruanne) is a mandatory narrative description of your company's activities. There is no minimum length requirement, but it should meaningfully describe:

• Your main business activities during the year
• Significant events after the balance sheet date
• Future plans and risks
• Research and development activities (if any)

A typical e-Resident OÜ management report is 3–5 sentences. For example:

"During 2025, the company provided software development consulting services to clients in the EU and USA. The company had one director and no employees. Turnover was €XX,XXX. There were no significant events after the balance sheet date. The company plans to continue its current business activities in 2026."

Common Mistakes to Avoid

1. Missing the Deadline

EMTA and the Business Registry both monitor annual report submissions. First offense: warning letter. Continued failure: fines up to €3,200. Repeated failure: compulsory dissolution.

2. Confusing Net and Gross Revenue

Your income statement should show net revenue (excluding VAT). Revenue on Estonian invoices is the amount before VAT.

3. Not Including All Directors

If your OÜ has multiple management board members, all must digitally sign the annual report. Forgetting a co-director will cause the submission to be rejected.

4. Using the Wrong Format

If your company grew past micro-entity thresholds during the year, you must use the higher reporting format. Check the criteria before starting.

5. Ignoring €0 Revenue Companies

Even if your company had no revenue and no transactions in the year, you must still file an annual report showing €0 balance sheet items.

Penalties for Late or Missing Annual Reports

Frequently Asked Questions

Can I file the annual report myself without an accountant?

Yes, if you understand basic accounting. The e-Business Register wizard simplifies the process considerably for micro-entities. However, if you have multiple revenue streams, cross-border transactions, or VAT, using an accountant reduces the risk of errors.

What if my financial year doesn't match the calendar year?

Your annual report covers your financial year as registered in the Business Registry. The 6-month deadline starts from the last day of your financial year, not December 31.

Is the annual report the same as my tax return?

No. The annual report goes to the Business Registry (äriregister). Your corporate income tax return (if applicable) goes to EMTA. These are separate filings.

How much does it cost to file the annual report?

Filing the annual report is free. If you hire an accountant to prepare it, costs typically range from €150–€500 for a simple micro-entity OÜ.

Can I amend the annual report after submission?

Yes. If you find an error after submission, you can file a correction report via the e-Business Register.
