Sweden’s tax agency has ordered six cryptocurrency mining companies in Boden to pay roughly 540 million Swedish kronor, about $56 million, in additional taxes and penalties, according to a disclosure by public broadcaster SVT on September 3. Skatteverket says the firms disguised mining activity to claim data-center tax benefits they did not qualify for.
The demands are part of an industry audit running from 2024 to 2026. Nine companies across Sweden have received adjustments totaling more than 500 million SEK, but the Boden cluster accounts for the bulk of the recent wave. The northern city became a magnet for energy-intensive computing after local hydro power kept electricity costs low, and several international operators set up facilities there over the past five years.
What the agency claims
According to reporting by Crypto Briefing and Cryptonomist, Skatteverket’s case rests on how the companies structured and reported their operations. Sweden grants favorable treatment to certain data-center activities, and the agency argues that crypto mining was hidden inside structures designed to qualify for those benefits. The reassessments include penalties on top of the back taxes.
Sweden taxes crypto gains as capital income at a flat 30% rate, and every disposal is a taxable event, so the rules for individuals are settled. The dispute in Boden is different: it concerns corporate structures and the classification of what a facility actually does, not how investors report profits. That makes the cases harder to resolve and more consequential for other operators, because a court ruling on classification will apply across the sector.
Bikupan Datacenter, a company tied to Canada-listed HIVE Digital Technologies, is fighting its assessment at Sweden’s Supreme Administrative Court. The outcome will shape whether the agency’s interpretation of mixed-use facilities holds up. Court timetables in Sweden run long, and a final ruling could take years.
HIVE pivots the site anyway
HIVE is scaling down bitcoin mining at Boden regardless of the court fight and converting the facility into a liquid-cooled AI data center designed to host 2,000 Nvidia GPUs. The company has spent the past year steering its business toward high-performance computing as mining margins tighten, and the Swedish tax dispute adds pressure to a shift it had already announced. Converting the site also changes its tax profile going forward, since an AI hosting facility fits the data-center category far more cleanly than mining rigs.
The case echoes enforcement elsewhere in Europe. Norway cut subsidies that miners relied on, and Icelandic operators have faced scrutiny over energy use classifications. Sweden’s approach is narrower and financial rather than environmental: the state is not banning mining, it is retroactively repricing it. That distinction matters for the companies involved, because penalties on top of back taxes can exceed what a going concern can absorb, and two of the smaller Boden firms have reportedly disputed their ability to pay in full.

What it means for the sector
Operators in Sweden now face a compliance question that goes beyond paying up: how to document what a facility actually computes. Firms that mix AI workloads with mining will need clean separation in their reporting, because the agency has shown it will reclassify blended operations. Legal observers expect more assessments before the audit window closes, and the Boden demands are likely to be contested for years given the court backlog.
The timing is awkward for an industry already squeezed. Bitcoin’s hashrate sits near record levels while the coin trades around $79,000, and margins per terahash have compressed through 2026. Companies planning European expansion now have one more jurisdiction to model for regulatory risk, and Sweden’s reputation as a cheap, green mining destination has taken a hit that hydro prices alone will not fix.
For now the numbers stand as demanded. Skatteverket has not commented beyond its published decisions, and none of the six companies has named a settlement plan.
