The Danish Tax Agency is authorized to obtain information about Danes who trade on crypto exchanges.

This is done in practice through cooperation with tax authorities in other countries with which Denmark has data exchange agreements on tax matters.

Thus, the Tax Agency can request information about Danes who trade on crypto exchanges in other countries. However, the authorization does not allow for “fishing expeditions” for data on individuals but only for broad data collection on Danes active on these exchanges.

The EU has adopted a new directive on data exchange in crypto in 2023 (the DAC8 directive – Directive on Administrative Cooperation) which will lead to increased audits and control on crypto.
