The DTA, the Skattestyrelsen, was authorised by the Tax Council to obtain information on cryptocurrency traders from three local crypto exchanges.
The DTA said that this is the first time the council has allowed it to get access identification information on cryptocurrency traders, including names, address and central person registration.
The three unnamed exchanges will now have to provide information to the agency on all purchases and sales of cryptocurrencies made by their customers between January 2016 and December 2018.
In its application to the Tax Council, the DTA said it sought to “obtain information on unexecuted taxpayers’ and companies’ virtual currency transactions”.
The agency is in the process of contacting the exchanges to agree on the process of disclosure.
Once the information has been received, the agency will check that citizens who have trade cryptocurrency have paid the right amount of tax.
In addition, information on transactions made by foreign nationals and companies will be exchanged with the respective countries'' authorities.
Karin Bergen, personal tax director at the DTA, said:
"Without going too far, I think you can say that this is a big market that we need to look into. When we recently received information from the Finnish bitcoin exchange, it gave us a small tab of a larger picture, which we now have the opportunity to uncover even more of. However, how many traders it is about, or how much money has been traded, is still too early to tell about yet."
