Citation: Högsta förvaltningsdomstolen, dom meddelad i Stockholm den 19 maj 2026, mål nr 1334-25
Applicant: Kubikenborg Aluminium AB, 556032-8121
Respondent: Skatteverket
Jurisdiction: Sweden
Judgment date: 19 May 2026
Judgment Summary
Kubikenborg Aluminium AB (Kubal) is a Swedish primary-aluminium manufacturer operating within an international group whose ultimate parent, United Company Rusal Plc (Rusal), is tax-resident in Cyprus. Kubal's production activities were governed by a conversion agreement with a group company, RTI Limited (RTI), tax-resident in Jersey, under which Kubal received reimbursement of its conversion costs plus a six-percent mark-up.
Kubal had a fixed-price electricity supply agreement with the Swedish supplier Vattenfall for 2008–2016, which Rusal had guaranteed. In February 2016, Kubal terminated the agreement early. Following arbitration proceedings, Kubal paid damages to Vattenfall. Kubal deducted the damages and related costs, totalling approximately 211 million kronor, in its income tax return. Rusal subsequently made an unconditional shareholder contribution to Kubal of approximately 204 million kronor.
Skatteverket applied the correction rule in Chapter 14, section 19 of the Income Tax Act (inkomstskattelagen, 1999:1229) and increased Kubal's taxable result by an amount equal to the deducted damages. Skatteverket also imposed a tax surcharge. Both the Administrative Court in Härnösand and the Administrative Court of Appeal in Sundsvall upheld Skatteverket's decision.
The Supreme Administrative Court set aside those decisions, finding that the preconditions for applying the correction rule were not met. It awarded Kubal costs of 186,365 kronor in the Supreme Administrative Court.
Background
Kubal is part of an international aluminium-manufacturing group. The group's parent company, Rusal, is tax-resident in Cyprus [paragraph 3]. Kubal operates a factory producing primary aluminium. Under a conversion agreement with RTI, Kubal receives raw materials from RTI, processes them into primary aluminium, and delivers the product back to RTI. Kubal is paid its conversion costs plus a six-percent mark-up [paragraph 3].
Electricity is a significant input in aluminium production. Kubal entered into an electricity supply agreement with the Swedish supplier Vattenfall for 2008 to 2016, under which Kubal committed to purchasing a minimum quantity of electricity at a fixed price. Rusal issued a parent-company guarantee in connection with that agreement, covering Kubal's obligations to Vattenfall [paragraph 4].
The electricity agreement became unfavourable relative to world-market electricity prices. In February 2016, Kubal terminated the agreement early. The expected cost saving was approximately 257 million kronor [paragraph 5]. Following arbitration, Kubal paid damages to Vattenfall. Kubal deducted the damages and related costs totalling approximately 211 million kronor in its income tax return. Rusal then made an unconditional shareholder contribution to Kubal of approximately 204 million kronor [paragraph 5].
Core Dispute
Skatteverket applied the correction rule under Chapter 14, section 19 of the Income Tax Act and increased Kubal's taxable result by an amount equal to the deducted damages [paragraph 6]. Skatteverket's position was that the electricity agreement had only been possible because of the parent-company guarantee, that Rusal controlled and had the financial capacity to bear the risk of the agreement whereas Kubal did not, that Kubal had no independent interest in terminating the agreement because under the conversion agreement it received full reimbursement of electricity costs, and that Rusal had instructed Kubal to terminate the agreement and allow the damages to reduce Kubal's result [paragraph 7]. Skatteverket argued that an independent party would never have accepted the risk of paying damages without receiving profit-based compensation, and that the shareholder contribution did not affect taxable results [paragraph 8].
Kubal argued that consulting Rusal before the termination did not give rise to an agreement or transaction between Kubal and Rusal that could be examined under the correction rule, that Kubal had not ultimately borne the cost because of the shareholder contribution, and that what Skatteverket was in substance challenging was the pricing model in the conversion agreement with RTI [paragraph 11].
Court Findings
The Supreme Administrative Court stated that the correction rule requires, among other things, agreed terms that deviate from arm's-length terms, a resulting reduction in the Swedish taxpayer's result, and a corresponding increase in the result of a related party not subject to taxation in Sweden. The burden of proof lies with Skatteverket [paragraph 19].
The court accepted that an agreed term within the meaning of the correction rule can exist even without a formal written agreement, and that conduct can constitute a transaction even if the parties have not themselves characterised it as such, with reference to paragraph 1.49 of the OECD Transfer Pricing Guidelines (2022 edition) [paragraph 22]. The court therefore accepted that Kubal's termination of the electricity agreement and payment of damages, without compensation other than a shareholder contribution, could in principle constitute terms of a transaction examinable under the correction rule [paragraph 23].
The court held that the assessment of arm's-length terms and risk allocation must take a broader perspective, encompassing the business and production model applied to Kubal within the group, and in particular the role given to Kubal under the conversion agreement with RTI, with reference to paragraphs 1.34, 1.36, 1.38, and 1.51 of the OECD guidelines and to RÅ 1991 ref. 107 [paragraphs 26 and 27].
The court found that the conversion agreement meant that Kubal received full reimbursement of its electricity costs regardless of their amount, so Kubal was not exposed to the risk of the electricity agreement. While the parent-company guarantee meant that part of the risk fell on Rusal, RTI in practice bore the costs of Kubal's manufacturing process through the conversion agreement, including electricity costs. RTI therefore received both the upside and the downside of the electricity agreement proving favourable or unfavourable, with reference to paragraphs 1.81 and 1.84 of the OECD guidelines. The court concluded that the risk of the electricity agreement was borne primarily by RTI and only secondarily by Rusal [paragraph 30].
When Kubal terminated the agreement, the damages were not treated as a conversion cost to be reimbursed by RTI. The termination resulted in a lower taxable result for Kubal and a higher result for RTI, because the electricity cost reimbursement payable by RTI to Kubal decreased [paragraph 31].
Skatteverket had not asserted that the damages should have been reimbursed by RTI under the conversion agreement, nor that the conversion agreement was not at arm's length in any respect. Skatteverket's case was confined to claiming that the reduction in Kubal's result was matched by an increase in Rusal's result [paragraph 32].
The court acknowledged that lower group electricity costs would have had a positive effect on consolidated group results and, in consequence, on Rusal's result, but held that this was not the same as saying that income had been transferred from Kubal to Rusal within the meaning of the correction rule [paragraph 33]. The court therefore concluded that the preconditions for applying the correction rule were not satisfied [paragraph 34].
Outcome
The Supreme Administrative Court set aside the decisions of both lower courts in the parts concerning income tax and the tax surcharge [operative part of the judgment]. It awarded Kubal costs of 186,365 kronor in the Supreme Administrative Court [operative part and paragraph 35]. Skatteverket had proposed that costs be awarded at 80,000 kronor [paragraph 12]. The court found the amount claimed by Kubal to be reasonable [paragraph 35].
TP Method Highlighted
The case concerned the correction rule in Chapter 14, section 19 of the Income Tax Act (inkomstskattelagen, 1999:1229), which codifies the arm's-length principle for cross-border related-party transactions [paragraphs 1, 2, and 16]. The court referred to the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations (2022 edition), specifically paragraphs 1.34, 1.36, 1.38, 1.49, 1.51, 1.81, 1.84, and 1.98, as interpretive guidance, consistent with prior Supreme Administrative Court authority including RÅ 1991 ref. 107 and HFD 2016 ref. 45 [paragraphs 17, 22, 25, 26, and 30]. No specific OECD transfer-pricing method (such as the comparable uncontrolled price method or cost-plus method) was applied or discussed; the analysis centred on identifying the relevant transaction and allocating risk within the group structure.
Major Issues / Areas of Contention
- Whether a consultation between a subsidiary and its parent, followed by the subsidiary terminating a third-party contract and paying damages while receiving only a shareholder contribution in return, constitutes a transaction with agreed terms examinable under the Swedish correction rule.
- Whether the correction rule requires that a reduction in the Swedish taxpayer's taxable result corresponds to an increase in the result of a specific related foreign party, rather than a general improvement in consolidated group results.
- How risk allocation under the correction rule should be assessed where a parent-company guarantee and a separate intra-group conversion agreement interact, so that the primary economic risk of a third-party contract may be borne by a group company other than the guarantor.
- Whether the deductibility of the damages itself was in dispute, given that Skatteverket did not challenge the deduction as such but instead neutralised it through a result uplift under the correction rule.
- Whether Skatteverket could invoke the correction rule in relation to the Kubal-Rusal relationship without also challenging the arm's-length nature of the conversion agreement between Kubal and RTI.
