The Luxembourg parliament on 22 December 2016 adopted a resolution indicating that Luxembourg does not support the re-launched Common Consolidated Corporate Tax Base (CCCTB) proposal because it is regarded as incompatible with the subsidiarity and proportionality principle.

Furthermore, the parliament takes the view that the proposal is incompatible with the OECD Transfer Pricing Guidelines and the tax treaties signed by Luxembourg. The parliament is not convinced about the necessity of such far-reaching harmonization to combat tax evasion and fears that the proposal may have a substantial negative impact on the tax revenue for small economies.
