Estonia narrows retrospective investment-account declaration
For bank-held investment accounts, only those opened or taken into use in 2023 or later still qualify for retrospective declaration in table 6.5; the separate investment-firm transition is untouched.

Resident individuals who opened or took into use a bank-held investeerimiskonto in 2022 can no longer bring it into the investment-account system retrospectivelyEmta. Under updated Maksu- ja Tolliamet guidance, only accounts opened or taken into use in a bank in 2023 or later qualify for retrospective declaration of the account data in part I of income-tax table 6.5 and of contributions and withdrawals in part II
Emta. The previous threshold stood at 2022
Emta, so the cohort that opened in 2022 and relied on declaring late loses that route.
Retrospective declaration is the correction path for investors who failed to designate the account on time. A taxpayer who designates the bank account's IBAN as an investeerimiskonto in table 6.5 part I, and reports the movements on and off the account in part II, keeps the income-tax deferral on financial-asset gains: tax falls only on withdrawals exceeding the contribution balance. Correct and timely declaration in table 6.5 is the precondition for using the account and deferring the liability at all, and the financial assets must have been bought through the IBAN shown as the investment account in the return. Only that combination enables the deferral.
The boundary against the ordinary system is unchanged and now bites the 2022 cohort. Financial assets bought through an ordinary account cannot be folded into the investment-account system afterwards. A taxpayer who opened a bank account in 2020 or 2021, invested through it, but did not declare its IBAN as an investeerimiskonto in that year's table 6.5 part I must declare the sale of those assets in the ordinary system. With the retrospective-declaration right now closed to 2022 openers and the bar on folding ordinary-system assets into the investment-account system unchanged, a 2022 opener who missed the designation has no stated path left into the deferralEmta.
The separate transition for accounts with a contractual-state investment firm is untouched. An investeerimiskonto opened with an investment firm of a treaty state (for example Lightyear Europe AS) before 1 January 2024 may still be declared retrospectively in the 2024 return's table 6.5 parts I and II under the tulumaksuseadus transition provision, and only the acquisition cost of assets held on such an account may be declared as a 2024 contribution. That 2024 change applies solely to investment-firm accounts; the transition provision does not cover accounts opened and used earlier in banks.
In practice, the simplest path remains sending the investeerimiskonto report from the internet bank (LHV Pank, SEB Pank, Swedbank, Luminor Pank) to Maksu- ja Tolliamet before starting the return, so the table 6.5 data arrives pre-filled; manual entry line by line stays possible. A filed return can be corrected afterwards, and a parent declares a minor child's investment account every year regardless of movements. Taxed dividends and interest already declared elsewhere and routed onto the account are entered as contributions, increasing the tax-free balance carried forward. The deferral mechanics rest on tulumaksuseadus § 172, and the investment-firm retrospective route on its § 61(671) transition provision, which the guidance states does not extend to accounts opened and used earlier in banks.
Review clients with bank-held investment accounts opened or taken into use in 2022: where the IBAN was never designated in table 6.5, plan disposals under the ordinary system instead of the deferral.
