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

Delay	Sanction
Up to 3 months	Warning letter & initial fine (typically €200–€300)
Over 3 months	Repeated coercive fines up to €3 200 total
Persistent non‑compliance	Court‑ordered compulsory dissolution of the company

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

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

Month	Task
Jan‑Feb	Close previous FY in accounting; reconcile balances
Mar	Draft financial statements; collect supporting documents
Apr	Management review; prepare notes & management report
May	Board approves package; send to auditor (if required)
Jun	Shareholders’ meeting adopts the report; board member signs; submit by 30 Jun

Submitting early avoids last‑minute e‑system congestion.
