What was Sweden's electricity tax break for data centres?

Data centres could cut their energy tax on electricity by deducting it in their tax returns or applying for a refund. In February 2022 the Supreme Administrative Court ruled, in case HFD 2022:5, that a site where crypto mining is carried out can count as a data centre for this purpose, but only if mining is the company's main activity.

Later that year the government proposed scrapping the reduction for all data centres. Its September 2022 memo cited energy efficiency and pressure on electricity supply after Russia's invasion of Ukraine. Skatteverket confirms that the reduction ended on July 1, 2023. Since then data centres cannot deduct the tax in their excise returns or apply for refunds, though a separate deduction may apply in some northern municipalities.

It found the firms had used structures that hid their mining in order to claim relief meant for ordinary data centres. Of 18 mining companies the agency investigated over four years, 13 were set up in Boden.
