Income tax shall only be paid on deposit interest by those private individuals, who are Estonian tax residents and who have not informed the bank that their account, in which the interest is received, is an investment account.
Estonian tax resident is a person, whose permanent residence is in Estonia or who has stayed in Estonia for at least 183 days in a year. For tax purposes the residence can be verified in the internet bank (“Information and settings” → “Details”).
An investment account enables an active investor to postpone the income tax liability and reinvest the earned return without paying the income tax in between.
It is wise to carefully consider which accounts should be classified as investment accounts. Most definitely it is not reasonable to do it with your daily current account, since declaration of the same at a later date will be extremely complicated.
The choice of investment account can also be made in the internet bank. “Information and settings” ➞ “Accounts and limits” → “Accounts”. Choose the account and save the selection. Later you should also declare this account on your income tax return as an investment account.
