On 30 December 2019, the German Official Gazette published a law implementing EU directive on reporting requirements for cross-border tax planning arrangements. The directive commonly referred to as DAC 6 which require the taxpayers and intermediaries including EU-based tax consultants, banks and lawyers to report certain cross-border arrangements to the relevant EU member state tax authority.

The law entered into force on 1 January 2020 and will apply for reportable arrangements from 1 July 2020. Reportable arrangements must also be disclosed where the first step for implementation was taken after 24 June 2018 and before 1 July 2020, with the deadline set at two months after 30 June 2020.
