On 18 September 2026, the State Tax Inspectorate under the Ministry of Finance of the Republic of Lithuania (VMI) officially approved the Rules for the Use of Self-Service (Savitarnos taisyklės), marking a significant milestone in the digitalization of tax administration under the “New Generation Lithuania” project financed by EU recovery funds. The new regulation establishes the legal framework for taxpayers to interact electronically with the tax authority, covering authentication methods, submission of declarations, access to individual tax accounts, and the use of qualified electronic signatures. The rules enter into force on 1 October 2026 and replace previous administrative guidelines, aiming to reduce administrative burden, accelerate service delivery, and ensure full audit trails for all digital interactions. The VMI emphasized that the self-service portal will become the primary channel for tax compliance activities, including VAT returns, income tax declarations, and excise reporting.
Key Takeaways
- Mandatory Digital Transition: Starting 1 October 2026, all taxpayers registered for VAT and corporate income tax must use the VMI self-service portal for filing returns and communications; paper-based submissions will only be accepted in exceptional cases with prior authorization.
- Enhanced Authentication & Legal Validity: The rules mandate the use of qualified electronic signatures (QES) or the national e-identity system (E. Sąskaita) for all legally binding actions, ensuring non-repudiation and compliance with eIDAS Regulation standards for cross-border recognition.
- Real-Time Compliance Monitoring: The portal integrates automated validation checks for VAT numbers, VIES status, and excise license validity, enabling immediate error detection and reducing the risk of penalties for incorrect filings.
