스웨덴 세무 당국이 AI 컴퓨팅 운영으로 전환 중인 암호화폐 채굴 기업을 감시하며, 자산 재분류 및 감가상각 일정과 관련된 준수 문제를 제기하고 있다.

Swedish tax authorities are contesting hundreds of millions of kronor in VAT deductions claimed by northern data center operators, making the distinction between cryptocurrency mining and computing services a critical test for an industry racing to repurpose mining facilities for AI infrastructure.

The Swedish Tax Agency has issued proposed VAT decisions against subsidiaries of Northern Data AG and secured appellate rulings against two Swedish subsidiaries of HIVE Digital (NASDAQ: HIVE). Both companies maintain that their facilities provided computing capacity or infrastructure services to identifiable customers. The agency, however, contends that at least part of the activity constituted cryptocurrency mining, which falls outside the VAT system and therefore disqualifies businesses from deducting input VAT on equipment and related expenses.

These enforcement actions coincide with a separate dispute involving the European Commission, which is challenging a Swedish rule mandating that clients withhold 30% of payments to certain foreign contractors. Although the case, currently before the Court of Justice of the European Union, does not involve cryptocurrency mining or input VAT, it has drawn broader attention to Swedish tax regulations that can create significant cash-flow strain prior to final liability determinations.

The financial and operational consequences are increasingly shaping capital deployment strategies. HIVE has explicitly tied its decision to scale back cryptocurrency mining operations in Sweden to the ongoing tax disputes and enforcement measures. While Northern Data’s strategic pivot was already underway, its Swedish VAT investigation has accompanied its broader transition from a cryptocurrency miner to an AI-cloud and data center operator.

This dynamic has created a complex transition for northern Sweden. Historically, the region drew data center investment due to abundant hydropower, cool climates, and reduced electricity taxes until 2023. Today, these same industrial sites are being repositioned for AI workloads, even as legacy mining activities continue to trigger tax assessments, appeals, and, in Northern Data’s case, a criminal probe.

According to Swedish Tax Agency guidance, cryptocurrency mining does not qualify as a taxable service because there is no identifiable counterparty receiving proof-of-work blockchain rewards. The agency extends this logic to transaction-verification fees where payers and verifiers remain unidentifiable, placing such activities entirely outside the VAT framework.

This classification carries significant financial implications beyond how mining revenue itself is taxed. Businesses typically deduct input VAT on purchases tied to taxable supplies. However, if servers, electrical infrastructure, and operational services are deemed used for non-VAT activities, the agency can revoke those deductions or demand repayment of previously issued refunds.

The underlying business models further complicate the dispute. Both HIVE and Northern Data assert that their Swedish entities supplied infrastructure, hashrate, or related computing services to third parties. Under this model, the commercial transaction involves selling computing capacity to an identifiable client—such as a mining pool—rather than the company mining cryptocurrencies for its own balance sheet.

Supplying AI-cloud capacity generally aligns more easily with standard VAT frameworks, as it typically involves formal contracts, identifiable clients, and clearly defined computing services. Nevertheless, this does not guarantee favorable treatment for all data centers. Tax authorities retain the right to scrutinize actual equipment usage, control structures, and whether contractual arrangements accurately reflect underlying operations.

Northern Data’s Swedish exposure escalated publicly in September 2025, when law enforcement conducted raids on company-linked premises in Frankfurt, Boden, and Luleå. Four individuals were arrested amid an investigation into alleged large-scale VAT fraud exceeding €100 million. No criminal charges have been filed against the company, and the matter remains under active investigation.

Northern Data stated it was taken aback by the escalation, asserting that authorities misunderstood the tax treatment of its GPU cloud offerings and the economic and legal structure of its legacy cryptocurrency mining operations. The company emphasized its full cooperation and maintained compliance with international tax standards.

Subsequent transaction filings provided additional context. A prospectus prepared for Rumble Inc.’s acquisition of Northern Data revealed that the Swedish Tax Agency audited three subsidiaries: Decentric Europe BV, Hydro66 Svenska AB, and Hydro66 Services AB.

The agency issued proposed decisions concluding that specific activities at Northern Data’s Boden facility constituted non-VAT cryptocurrency mining. It sought to deny previously claimed input VAT of approximately 300 million kronor (€28 million) at Decentric Europe and 218 million kronor (€20 million) at Hydro66 Svenska. These amounts include potential penalties but exclude accrued interest.

Northern Data formally contested the Decentric proposal and indicated plans to challenge the Hydro66 assessment. The company argued that its operations involved supplying infrastructure and services to third parties, qualifying as taxable supplies. It further suggested the agency may have relied on incomplete operational data and assumptions that misaligned with actual commercial arrangements.

At the time of the prospectus, the proposed decisions had not yet matured into final assessments. Consequently, Northern Data did not recognize a financial provision, determining that an outflow was not probable, but disclosed the exposures as contingent liabilities.

Prior to the Rumble transaction, Tether served as Northern Data’s controlling shareholder and committed up to $200 million to cover certain tax liabilities should they become payable or require accrual. While this backing provides crucial liquidity, transaction documents cautioned that it does not erase the underlying economic burden.

HIVE’s dispute has advanced further through Sweden’s administrative court system.

Subsidiaries Bikupa Datacenter AB and Bikupa Datacenter 2 AB received a series of decisions starting in December 2022 that denied input-VAT recovery and mandated repayment of prior refunds, along with tax supplements and interest. HIVE appealed, contending that the rulings misapplied Swedish law and failed to account for the technical realities of its hashrate-services model.

Both the Administrative Court and Court of Appeal ruled against HIVE. On July 20, 2026, the company applied for leave to appeal to the Supreme Administrative Court, though Swedish legal counsel warned that the likelihood of a favorable ruling remained low.

Following these rulings, HIVE recorded an 822 million-kronor ($84.7 million) provision covering all disputed periods through June 2026. The non-cash charge comprises $76.6 million in VAT, $1.5 million in tax supplements, and $6.6 million in interest. The total exposure could rise as interest continues to accrue.

The provision surpassed HIVE’s $79.1 million in quarterly revenue and drove a $142.9 million net loss. With $208 million in cash on hand at the end of June, the accounting charge remains highly material despite requiring no immediate cash outlay.

HIVE maintains its opposition to the assessments, citing support from EU guidance, an advance tax ruling, a forensic technology analysis, and a legal opinion from a Swedish VAT professor.

HIVE is also escalating the dispute beyond domestic channels. In an August 11 regulatory filing detailing a delay in its quarterly report, the company announced proceedings with the European Commission, alleging that Swedish administrative courts systematically refuse to refer unresolved EU law questions to the Court of Justice of the European Union.

Additionally, HIVE disclosed preparations for a civil lawsuit against a Swedish government agency, seeking damages stemming from the tax authority’s handling of the VAT disputes. The company did not confirm whether the complaint had been filed, specify the target court, or disclose the amount of damages sought.

HIVE has explicitly linked its operational pivot in Sweden to tax enforcement pressures. In March, the company noted that stringent security requirements attached to disputed assessments and lingering uncertainty over input VAT deductions rendered its traditional hashrate-production model economically unviable in the region.

The company has begun scaling back ASIC-based computing at its primary Boden facility while retrofitting a separate 7-megawatt site to Tier III standards for AI and high-performance computing. HIVE is also evaluating a comparable upgrade for its 32-megawatt Big Boden campus and has executed a nonbinding letter of intent for up to 25 megawatts of colocation capacity.

This strategic shift forms part of HIVE’s broader expansion into GPU cloud infrastructure, extending beyond mere tax mitigation. Yet the company’s disclosures make clear
