Main field of activity

When you register your company, you will need to declare the main field of activity for your business.

You can operate in more than one field under the same company, but, at registration, only the main field of activity is to be selected. You can declare additional fields of activity at a later point.

Annually, you will confirm your fields of activity (or declare additional fields of activity) when you submit your annual report or file company taxes. 

How to choose your main field of activity

A good way to determine your main field of activity is to consider your business goal. If you have more than one activity, choose the one you think will generate the most value within the first fiscal year. 

You can search for the appropriate field of activity in the Estonian Classification of Economic Activities (EMTAK) tool. If you are working with a service provider, they can also advise.

EMTAK is a national version of the international NACE classification system that enables comparing economic statistics internationally. Fields of activity are classified similarly across the European Union.
