Investment account declaration in Lithuania 2026 is now possible: the State Tax Inspectorate (VMI) has confirmed that residents can now declare their investment account through the Electronic Declaration System (EDS). Due to delays in implementing the new functionality, VMI has extended the deadline for investment account declarers to 1 June 2026 — instead of the usual 4 May deadline. No late fees will be charged for this extended period.
- Who must declare: residents who used an investment account during 2025
- Extended deadline: 1 June 2026 (instead of 4 May)
- GPM refunds: still by 31 July 2026 (unchanged)
- Late fees: none for investment account declarers
- GPM support allocation: deadline 4 May — NOT EXTENDED
- Where to declare: EDS, wizard section H (deklaravimas.vmi.lt)
What happened: why was the deadline extended?
This year, for the first time, Lithuanian residents could declare their investment accounts as part of their annual income tax return. VMI needed to implement a new section — section H — in the EDS income declaration wizard, but the rollout took longer than planned.
VMI Deputy Head Martynas Endrijaitis acknowledged the situation openly: “We understand our clients’ concern and admit that the implementation of this functionality took longer than planned.” As a result, everyone declaring an investment account has been given an extra month — until 1 June. VMI confirmed that no late fees will apply during this extended period.
Once the functionality is fully ready and tested, VMI will announce this publicly. Watch the VMI website for updates if you haven’t yet filed.
What is an investment account and how does it work?
An investment account is a legally recognised investment model under Lithuanian tax law. Its key benefit is tax deferral: investment income is taxed only when you withdraw more money from the account than you originally deposited.
In practical terms:
- Dividends, interest, and capital gains — not taxed while they remain in the account
- Reinvested amounts do not increase the taxable base
- Personal income tax (GPM) is due only on the net withdrawal above the total deposited amount
An investment account can be an existing account or a newly opened one at a financial institution or payment service provider, either in Lithuania or abroad. However, funds held in the account must be used exclusively for investments in financial products permitted by Lithuanian law.
Who must declare an investment account?
Any resident who used an investment account during the 2025 tax year — meaning they deposited or withdrew funds, or held an active investment account under this model — must declare it.
The declaration is made as part of the annual income tax return in EDS, in section H of the wizard. If you have not yet filed your 2025 income tax return, you can include the investment account data at the same time.
What if I already filed without investment account data?
If you already submitted your 2025 income tax return but did not include investment account data — even though you used an investment account that year — you can file a corrected declaration. Simply submit an amended return with the investment account data added to section H.
How to declare your investment account — step by step
- Log in to EDS at deklaravimas.vmi.lt.
- Open the income tax declaration wizard (new filing) or submit a corrected declaration (if already filed without investment account data).
- Navigate to section H — this is where investment account data is entered.
- Enter account details: name of financial institution, account number, total amounts deposited and withdrawn during 2025.
- Review the calculation — EDS will automatically compute whether taxable income exists (only if withdrawals exceeded deposits).
- Submit by 1 June 2026 — no late fees apply under the extended deadline.
Practical example: investor Tomas
In January 2025, Tomas opened an investment account and deposited €5,000. During the year he bought and sold shares — his portfolio grew — but he made no withdrawals. By December, the account held his original €5,000 plus €800 in unrealised gains.
Tomas’s GPM liability: zero. Because he made no withdrawals, no taxable event occurred — even though the portfolio value increased. However, he still needs to declare the investment account in section H. He submits the declaration by 1 June 2026.
If Tomas withdraws €6,000 in 2026 — €1,000 more than he deposited — that is when a GPM liability arises, and only on that €1,000 difference.
Key dates: investment account 2026
- By 4 May 2026: GPM support allocation request (2% / 1.2%) — NOT EXTENDED
- By 1 June 2026: income tax declaration for investment account holders (extended)
- By 31 July 2026: GPM refund payment (unchanged)
Frequently asked questions
Does every resident need to declare an investment account?
No — only those who used an investment account during 2025 (made deposits or withdrawals). If you had no investment account or did not activate one, you do not need to complete section H.
Does the extended deadline apply to other income too?
The extension to 1 June applies only to those declaring an investment account (section H). If your return does not include an investment account, the standard 4 May deadline still applies.
What if my investment account is held abroad?
Foreign investment accounts that meet the statutory criteria can also be declared as investment accounts. Enter them in section H. If you are unsure whether your account qualifies, consult VMI.
Will my GPM refund be paid on time if I file by 1 June?
Yes. VMI confirmed that refunds will still be paid by 31 July 2026, regardless of whether the declaration was submitted by 4 May or under the extended 1 June deadline.
Can I allocate GPM support at the same time as declaring my investment account?
You can allocate GPM support, but the request must be submitted by 4 May — even if the declaration itself will be filed later. Support allocation and the extended declaration deadline are separate processes.
