The Estonian Tax and Customs Board (ETCB) has summed up the errors it sees most often when people declare investment accounts on their personal income tax return. The board says the system has grown fast: in 2020 fewer than 20,000 people had an investment account, while for 2025 more than 87,000 people declared over 132,500 accounts.
An investment account lets a person reinvest profit without paying income tax at once. As the board's risk manager Janelle Urres put it: The income tax liability only arises when the amount withdrawn from the account exceeds the contributions made to it
. For that deferral to work, the account has to be declared every year, including years with no withdrawals, and a parent must declare an account opened for a minor child. After the board sent reminders in the autumn, account holders declared their missing contributions and payments, and declared income tax liability rose by nearly half a million euros.
Reports from LHV, Luminor, SEB, Swedbank and Lightyear can be sent to the board before the return is filled in, but the prefilled figures must be checked, and accounts held abroad are entered by hand. Returns can be corrected only for up to three years back, so contributions missing from older returns can no longer count.
The board also warns that not every platform qualifies as an investment account, for example some crowdfunding or crypto-asset platforms, and that the account should not be used for day-to-day spending.

What this means for an Estonian entrepreneur
Owners of Estonian companies often receive dividends into a personal investment account. The board's reminder is that the account must be declared every year and that corrections are possible only three years back, so dividends paid out by the company and the owner's own records should match each year.
