On 30 July 2020, the Lithuanian State Tax Inspectorate released amendments to the Mandatory Disclosure Regime (MDR) rules to introduce a six-month postponement of the European Union (EU) Directive on Mandatory Disclosure and Exchange of Cross-Border Tax Arrangements. The amendments follow the adoption of a Directive on 24 June 2020 by the Council of the EU allowing EU Member States an option to defer, for up to six months, the time limits for the filing and exchange of information on cross-border arrangements under DAC6. The amendments came into force on 31 July 2020.

The Lithuanian MDR law was passed on 30 July 2019 and is largely aligned with the requirements of the directive.
