Sweden’s Tax Agency has increased tax assessments by about 540 million Swedish kronor against six cryptocurrency companies in Boden, alleging they used corporate structures to obtain improper tax benefits, and the decisions have been upheld after legal appeals.

The Tax Agency’s action centers on six crypto companies based in Boden, a northern Swedish town that has attracted data-center and mining activity. According to the agency, the companies used structures designed to secure undue tax advantages. Patrik Lillqvist, the agency’s head of intelligence, said the companies were circumventing the law.

The largest disclosed case involves Bikupan Datacenter AB, which was assessed 477 million Swedish kronor in additional taxes. The company is described as being linked to Bitcoin miner HIVE, though the precise nature of that relationship was not detailed. The original report said Bikupan has entered judicial recovery, signaling serious financial strain following the tax decision.

Bikupan Chief Executive Johanna Törnblad disputed the agency’s position, arguing that the mining itself is conducted by external pools. The legal appeals did not reverse the tax authority’s decisions, leaving the assessments in place and increasing pressure on the affected firms.

The case comes as tax scrutiny of the crypto sector in Sweden appears to be rising. A 2024 investigation cited in the report said companies in the sector had avoided 1 billion Swedish kronor in taxes. At the same time, mining operators globally have been dealing with tighter economics after Bitcoin’s halving, which reduces mining rewards every four years, and some have been looking at artificial intelligence infrastructure as an alternative line of business.

Why It Matters

This is more than a local tax dispute. It highlights a core risk in the mining business model: even where energy access and infrastructure are favorable, regulatory and tax treatment can materially affect whether operations remain viable. For crypto companies using layered operating structures, the Swedish case may prompt closer review of how mining, hosting, and pool relationships are documented and taxed.

The development also matters for jurisdictional competition. Countries that once looked attractive for mining can become less appealing if compliance costs and legal uncertainty rise. That could influence where future mining and related compute capacity are deployed, especially as some operators weigh a shift toward AI-linked infrastructure.
