In Estonia, merger control stops feeling theoretical the moment a deal starts to brush against the official turnover tests. The official Estonian Competition Authority overview says a concentration is subject to control if, in the previous financial year, the aggregate turnover in Estonia of the parties exceeded €6,000,000 and the aggregate turnover in Estonia of each of at least two parties exceeded €2,000,000. For the wider transaction picture, keep our Estonia M&A guide and share purchase versus asset purchase article open beside this note.
Deals rarely slow down because somebody forgot the headline number. They slow down because the buyer mapped local turnover too late, trusted stale accounts, or built a closing timetable that assumed clearance would look after itself.
What are the Estonian merger control thresholds in 2026?
The official 2026 threshold test is two-layered. Aggregate Estonia turnover of the parties must have exceeded €6,000,000 in the previous financial year, and the Estonia turnover of at least two parties must each have exceeded €2,000,000. The same official page also states that the state fee for concentration proceedings is €1,920.
That means size alone is not enough. One very large buyer does not complete the test by itself if the second side of the deal has only limited Estonia turnover. The threshold exercise belongs in the first diligence call, not the final signing checklist.
| Item | Official position | Why it matters |
|---|---|---|
| Aggregate Estonia turnover | More than €6,000,000 | First gate into control |
| At least two parties | Each above €2,000,000 in Estonia | Prevents one-sided size from dominating the test |
| State fee | €1,920 | Needs to be budgeted early |
Which turnover numbers actually matter?
The number that matters is Estonia turnover in the previous financial year. A group slide, a global revenue chart or a management estimate is not enough on its own. The cleanest way to run the threshold check is to line up the official corporate record with the freshest finance pack you can get.
Two official sources help here. The RIK business register queries page says users can search legal entities by name or registry code and use the visualisation tool to inspect relationships. The RIK annual report page says the annual report and related documents must be submitted within six months of the end of the financial year. So do not stop at an old filed PDF. Ask for current interim numbers as well. While building that pack, our Estonia company formation guide and Estonian SPA drafting guide help keep the entity map and the closing mechanics aligned.
How much pressure does the filing timetable create?
According to the same Competition Authority overview, the Authority must make its first decision within 30 calendar days of submission of a notice of concentration. If supplementary proceedings are opened, that same source says the decision window can extend to four months from the beginning of those proceedings. That is where timetable pressure becomes real.
Thirty days sounds manageable in isolation. It stops sounding short once financing, banking KYC, board changes and signing conditions are all pulling on the same calendar. If the turnover numbers are close, notification analysis should sit near the front of the transaction workstream.
Does every Estonian share deal trigger merger control?
No. The official overview explains that the purpose of control is to avoid the creation or strengthening of a dominant position that may give rise to a significant impediment to effective competition. So a share deal is not reviewed just because shares move. Thresholds and transaction effect still matter.
Smaller OÜ acquisitions can be straightforward. The picture hardens when the group structure is layered, more than one Estonia revenue stream is in play, or the parties overlap in the same market. That is why buyers should read the threshold test together with our share versus asset purchase comparison and the broader Estonia M&A guide.
What do foreign buyers miss most often?
The first miss is treating consolidated group revenue as if it answered an Estonia turnover question. The second is relying on the last filed annual report without testing whether trading moved materially after year end. The third is spotting the €1,920 fee and the four-month supplementary risk too late.
A calmer method works better. Start with the official register extract. Put previous-year Estonia turnover next to the current interim numbers. Then draft the SPA so the notice, the long-stop date and the closing conditions all reflect the same threshold analysis. That order saves time later.
How should you run a quick threshold check?
A useful quick check needs four items: group chart, official register output, latest filed annual report and current interim revenue pack. Once those four sit on one page, the threshold test stops being an abstract legal note and becomes a real transaction input.
Corpenza usually tells buyers to settle the deal structure first, then tighten the SPA mechanics, and only then freeze the notice and closing timetable. It sounds plain. It works.
FAQ
Is the €6,000,000 test based on global turnover?
No. The official overview speaks about turnover in Estonia, so country-level revenue mapping matters.
How many parties need to exceed €2,000,000?
At least two parties. One very large buyer does not satisfy that limb on its own.
How long is the first review window?
The official page says 30 calendar days from submission of the notice. If supplementary proceedings begin, the window can extend to four months from that point.
Is there a state fee?
Yes. The same official overview states a €1,920 state fee for concentration proceedings.
Is this article legal advice?
No. This is general information, not legal or tax advice. Notification analysis depends on the facts and the market position of the parties.
If you are buying an Estonian company, put the threshold check on the table in week one. When it is left for the last week, the timetable usually changes.
