In 2025, Austria quietly abolished a VAT exemption it had maintained for years, and in doing so, opened a VAT Pandora's box. The Austrian Federal Finance Court looked past the specific taxable person's complaint and asked a bigger question: whether this VAT exemption is even legal under EU law? Now that the Court of Justice of the European Union (ECJ) has announced its decision, years of exempt transactions across an entire sector may need to be unwound.

Background of the Case 

Following the tax audit in 2021, the Austrian Tax Authority concluded that certain cross-border services supplied to an Austrian-based bank that is the parent company of an Austrian VAT group by a contracting partner in relation to automatic teller machines (ATMs) did not qualify for the VAT exemption applicable to financial transactions under Austrian law. Consequently, the Tax Authority amended the bank’s VAT assessments for the relevant tax period and transferred the VAT liability to the bank.

The bank unsuccessfully challenged the amended VAT assessments by filing a complaint. After the Tax Authority denied the complaint, the bank appealed before the Austrian Federal Finance Court (FFC). The FFC noted that, in addition to reviewing the contested VAT assessments and examining issues raised by the bank, it must also identify any other legal errors and conduct any necessary factual investigations on its own initiative.

The FFC determined that the bank had applied a VAT exemption under Austrian law when submitting its VAT returns, and that exemption was the basis for the disputed VAT assessments. While neither party challenged the exemption's validity, the FFC raised doubts about the exemption's compatibility with EU law. 

Importantly, the FFC underlined that Austria abolished this VAT exemption on January 1, 2025, which, in its view, suggested that the Austrian legislature itself had doubts about whether the exemption was consistent with EU law. Due to these doubts, the FFC suspended the proceedings and referred the matter to the ECJ for a preliminary ruling.

Main Questions from Request For Ruling

The FFC raised one critical issue before the ECJ: could the Austrian VAT exemption for certain services supplied between businesses operating mainly in the banking, insurance, or pension fund sectors, where those services are directly used for carrying out VAT-exempt activities, be considered State aid under Article 107(1) of the Treaty on the Functioning of the European Union (TFEU)?

Applicable EU VAT Directive Article

The ECJ outlined Recital 5 and Articles 131, 135(1), and 168 of the EU VAT Directive as the most relevant for this case. While Recital 5 states that a broad-based VAT system ensures simplicity, neutrality, and the proper functioning of the internal market, the relevant articles focus on a general framework for VAT exemptions, specific mandatory exemptions for certain financial and insurance transactions, and govern the right to deduct input VAT, respectively.

In addition to these EU VAT Directive provisions, the ECJ also interpreted Article 107(1) of TFEU, which sets out the basic prohibition on incompatible State aid within the EU.

Austria's National VAT Rules

Regarding Austria's national VAT rules, the ECJ focused on Articles 6(1)(28), 6(1)(7) and (8), and 12(3)(2) of the Austrian Turnover Tax Act, which implements the EU VAT Directive into national law and provides for several VAT exemptions applicable to certain transactions.

Importance of the Case for Taxable Persons

This is one of the most significant cases for the Austrian banking and insurance sectors. If the ECJ determines that the VAT exemption in question constituted State aid, all transactions previously covered by the exemption would need to be reassessed. Consequently, this could lead to numerous disputes before national courts. This would also affect other EU countries with the same VAT exemptions in place.

Although this case centers on the financial sector, the ECJ's decision may affect any sector where EU countries have created special exemptions or favourable VAT treatments that are not explicitly listed in the EU VAT Directive.

Analysis of the Court Findings

After confirming that the request was admissible, the ECJ first set out to determine the precise scope of the exemption before answering the question referred. Under Austrian law, the exemption applied to certain services supplied between businesses primarily engaged in the banking, insurance, or pension fund sectors. More specifically, the exemption applied where those services were directly used to carry out VAT-exempt financial activities and also covered the provision of staff to qualifying groupings operating in those sectors. 

The ECJ observed that, even though the exemption was repealed in 2025, the relevant provision was applicable during the tax period at issue in the main proceedings. Therefore, it is necessary to assess its compatibility with EU law for the period in which it was in force.

In practice, the VAT exemption was applied very broadly and was not limited to licensed banks. It also covered other businesses primarily engaged in banking, insurance, or pension fund activities, even where they did not hold a banking licence. Since it was often difficult to determine whether particular services were used directly for VAT-exempt financial activities, the Austrian Tax Authority generally exempted all services supplied between qualifying undertakings that were not already exempt under other provisions.

The ECJ then turned to the State aid test, recalling that a measure constitutes State aid only if all four defined conditions are satisfied. These four conditions are that a measure must involve an intervention by the State or through State resources, confer a selective economic advantage on certain undertakings, distort or threaten to distort competition, and be capable of affecting trade between EU countries.

The ECJ determined that the exemption was not one of the VAT exemptions exhaustively listed in the EU VAT Directive, making the measure a national policy choice. Therefore, the ECJ had to determine whether the exemption involved State resources. The existence of State resources must be assessed from the perspective of the State and its budget, rather than from the financial position of the individual beneficiary. The determining factor is whether the measure reduces, or is capable of reducing, the tax revenue that the State would otherwise receive.

The ECJ determined that the Austrian legislature itself acknowledged that abolishing the exemption would generate additional VAT revenue for Austria in 2025 and the following years. This confirmed that the exemption had the potential to reduce State tax revenue and therefore involved the use of State resources for the State aid rules.

The ECJ then examined whether the VAT exemption provided an economic advantage and whether that advantage was selective. The conclusion was that the Austrian VAT exemption was capable of granting an advantage for businesses providing exempt services. Moreover, those businesses were the legal beneficiaries of the exemption because they could provide certain services without charging VAT, unlike businesses supplying comparable services that were not covered by the exemption and were required to add VAT to their prices.

Concerning the distortion-of-competition requirement, the ECJ noted that the assessment focuses on the potential effects of the measure rather than on evidence of an actual impact. Based on the established case law, the ECJ recalled that where an advantage is granted to an undertaking operating in a competitive sector, this alone may be sufficient to demonstrate that the measure has a real or potential effect on competition. 

Regarding whether the exemption could affect trade between EU countries, the ECJ stated that this condition is satisfied where State aid strengthens the position of an undertaking compared with competitors involved in intra-EU trade. It is not necessary to demonstrate that the aid has a direct impact on cross-border trade. Instead, it is sufficient that the beneficiary's strengthened competitive position affects competition within the internal market.

Notably, even if the VAT exemption could also benefit taxable persons established in other EU countries, it does not prevent the measure from affecting trade between EU countries. The key issue is whether the exemption strengthens the competitive position of the beneficiaries compared with businesses that do not benefit from it.

Court's Final Decision

The ECJ concluded that the Austrian VAT exemption at issue met the criteria for State aid because it involved State resources, granted a selective economic advantage to certain businesses, was capable of distorting competition, and could affect trade between EU countries.

Conclusion

Given that the ECJ refused Austria's request to limit the judgment's temporal effects, the ruling applies retroactively to any tax period not yet definitively closed under Austrian law. In practice, this means that Austrian banks, insurers, and pension funds that used this exemption face potential VAT reassessment for still-open years, likely turning what looked like an exempt B2B service into a taxable one, with related output VAT now due. On the other hand, tax periods definitively closed under Austrian law are protected, as the ECJ explicitly stated that those do not need to be reopened.
