Investment Account Deadlines: Key Choices & Last-Minute Tax Reminders for Lithuanian Residents

The Lithuanian Tax Authority (Valstybinė mokesčių inspekcija, VMI) has issued a final warning to taxpayers ahead of a critical deadline: fewer than two weeks remain to submit declarations under the new investment account regime or risk losing the opportunity to switch back to the old tax system.

The deadline, set for June 9, 2026, marks the last day for individuals to declare their assets under the revised tax framework introduced in 2025. Those who fail to act by the cutoff date will be automatically enrolled in the new regime, which imposes stricter reporting requirements and higher tax obligations on certain investments.

Over 19,000 residents have already submitted declarations, according to VMI data, but officials emphasize that thousands more remain at risk of missing the window. The authority has urged taxpayers—particularly those with foreign assets, real estate, or high-value investments—to prioritize compliance to avoid unintended tax liabilities.

Why the Deadline Matters

The new regime, designed to combat tax evasion, requires detailed disclosure of investment portfolios, including stocks, bonds, cryptocurrencies, and property. Failure to declare assets could trigger penalties, back taxes, or even criminal investigations in cases of willful non-compliance.

Taxpayers who opt for the old system must submit their declarations by June 9, after which the choice becomes irreversible. VMI has stressed that the transition is permanent, and switching back later will not be possible.

How to Declare

Residents can file declarations through the VMI electronic portal, where step-by-step guides and support are available. The authority has also activated a helpline for those requiring assistance, though demand has surged in recent days.

Key Notes for Taxpayers:

• The deadline is June 9, 2026 (no extensions are expected).
• Declarations must include all assets, including those held abroad.
• Late submissions may face penalties or automatic enrollment in the new regime.
• VMI has not confirmed whether partial declarations will be accepted.

While the new tax system aims to improve transparency, critics warn it could disproportionately affect middle-class savers and retirees with modest portfolios. VMI has not commented on potential reforms but has reiterated that compliance is mandatory.

For those still undecided, tax advisors recommend weighing the long-term implications of each regime before the deadline. The authority has pledged to process declarations promptly, but delays could arise if submissions spike in the final days.
