On 30 July 2019, the President signed the primary legislation implementing the European Union (EU) Directive on the mandatory disclosure and exchange of reportable cross-border tax arrangements (referred to as DAC6 or the Directive) into Lithuanian law. Under DAC6, taxpayers and intermediaries are required to report cross-border reportable arrangements from 1 July 2020.

The reporting requirements primarily apply for intermediaries that design, market, organize, or manage the implementation of a reportable arrangement. The reporting obligation may also be shifted to a taxpayer in some cases. The measures contained in the law for DAC6 are relatively limited, with the tax authority to issue the characteristics and conditions for reportable cross-border arrangements, the list of data to be reported, and the procedures for reporting.
