OECD dataset from agency OECD.CTP.TPS: DSD_QDD_ACT12@DF_QDD_ACT12 (2025 - 2025)
Dataset Description
The 2015 BEPS Action 12 report identified the lack of timely, comprehensive and relevant information on aggressive tax planning strategies as one of the main challenges faced by tax authorities worldwide. The report recommended the design of rules requiring taxpayers and/or advisers to disclose aggressive tax planning arrangements. These mandatory disclosure rules (MDRs) are intended to provide tax administrations with early information about such schemes, enabling them to respond more rapidly to emerging risks and target resources more effectively. The OECD gathers information on progress related to the implementation of Action 12, namely, whether a jurisdiction has MDRs in place and, if so, the main details of the rules including:
- the types of taxes covered (e.g. CIT, personal income tax, capital gains tax, VAT)
- the parties obliged to report
- the reportable transactions, schemes or arrangements under the MDR
- the information that must be disclosed to the tax authorities under the MDR
