Submission of the annual report is mandatory in any case.

Every Estonian legal entity – including micro‑sized OÜs owned by e‑residents – must file an annual report (majandusaasta aruanne) with the Business Register within 6 months after the end of its financial year (Commercial Code § 60).

Typical deadline: If your financial year = calendar year, the report is due 30 June of the following year. To change the FY you must submit a shareholders’ resolution and amend the articles in the Business Register before the new FY starts.

1. What must be included?

Estonian GAAP (Estonia’s Good Accounting Practice) recognises four size categories. Reporting requirements scale with size:

The size of the company determines which statements are required: micro-entities file only the balance sheet and income statement, whereas small entities add a cash-flow statement and management report, and larger ones include changes in equity and often an audit.

Most of our clients fall under micro or small category.

2. Penalties for late filing

Late filing also raises red flags with banks and partners; keep your compliance record clean.

3. Best‑practice timeline (calendar‑year FY)

Submitting early avoids last‑minute e‑system congestion.
