Tax Unanimity in the Age of Big Tech: Competing Policy Interests in the European Union

When three EU Member States exercised their tax veto to block the European Commission’s (“Commission”) interim Digital Service Tax (“DST”) proposal, Commission leaders felt justified in moving to permanently reform EU voting procedure. Valdis Dombrovskis, Executive Vice President of the Commission, urged his fellow lawmakers that “the blocking of the Digital Services Tax by a few Member States in the Council, and previous similar experiences, should be seen as a wake-up call concerning the need for the Union to gradually move towards qualified majority voting on tax matters.”[1] Because economists expected the tax to raise just €5 billion, it may seem odd that this particular failure triggered such a strong response. Even if the DST offered the best policy response to the global challenge of taxing multi-national tech giants, why did this policy rejection of an interim tax compel the Commission leader to label it a “wake-up call” that warranted permanent change in EU tax voting procedure? The answer has something to do with the Commission’s desire to tax the digital economy and a lot to do with the current EU balance of power on taxation. Ultimately, the controversy boils down to two important treaty provisions: the Council’s tax unanimity voting requirement and the obscure never-used Passerelle clauses that allow legislators to transition from unanimous to qualified majority voting (QMV) without amending any underlying treaties.[2]

To understand Dombrovskis’ comment, we must first recognize that a tension exists between the taxation goals of some Member States and the Commission responsible for advocating the interests of the entire Union. Seeking to strengthen the single market and better position the European Union globally, the Commission benefits from consolidated legislative control. Simultaneously, many small Member States rely on strategic tax programs to attract investment, especially from highly profitable tech companies in the increasingly competitive digital economy.[3] By offering regulatory advantages for tech investors, US tech companies benefit from the policies of these tech-friendly EU states and these small EU states in return attract much-needed capital and jobs. Sometimes, though, these Member State regulatory regimes conflict with the Commission’s broader objectives. However, since the current framework requires unanimity for EU action, states may unilaterally block any proposals deemed harmful to national interests. Relying on this procedural guarantee, any move by the Commission to eliminate unanimity risks infringing on the expectation by some states that Brussels fiercely guard what they see as an essential protector of national sovereignty.

Globally, the world’s six largest tech companies—Facebook, Apple, Amazon, Netflix, Google, and Microsoft, all US-headquartered—share a $4.5 trillion market capitalization.[4] Between 2010 and 2018, though, the global tax gap for these market leaders topped $100 billion.[5] This means that over those eight years, governments legally lost $100 billion in tax revenue. The discrepancy between big tech’s market dominance and lost tax revenue prompted the international community to seek much-needed international tax reform. And the European Union emerged, anxious to lead the way.[6] 

When global negotiations stalled, the European Union’s largest Member States lobbied the Commission to take more decisive action. In early February 2018, Germany, France, Italy, and Spain united to persuade the Commission to take action on Google, Amazon, Facebook, and Apple. Approximately one month later, on March 21, 2018, the Commission responded by launching its Digital Services Tax.[7]  Responding, in part, to the demands of its most powerful states, Commission leaders believed an interim plan, set to retire once the global community reached a consensus on taxing the digital economy, would signal its commitment to global tax reform. It also hoped that the move might incentivize broader international collaboration.[8] Many larger states, having lobbied for EU action, supported the proposal. They agreed that the European Union needed a temporary response and recognized that achieving international consensus could take years. However, the proposal met strong resistance from some of Europe’s smallest states, namely Ireland, Denmark, Malta, Sweden, and the Netherlands.[9] And, given tax unanimity, the proposal failed when Ireland, Denmark, and Sweden exercised their veto.[10]  

Codified in Articles 113 and 115 of the Treaty on the Functioning of the European Union, the tax veto is an integral feature of EU legislative procedure.[11] Periodically, however, veto exercise generates opposition. Critics consider tax unanimity inefficient and ill-suited to a Union of 446 million people. [12] So, after the DST’s failure, the Commission felt justified that the European Union must finally bid adieu to the tax veto. Valdis Dombrovskis argued that the proposal’s failure by veto represents just “another example of many tax initiatives where the unanimity requirement has hampered the progress needed to strengthen the single market and avoid its fragmentation.”[13] Not only does the veto inhibit EU progress, Dombrovskis stressed, it also limits Europe’s ability to act as a united force in global negotiations.[14] “Speaking with one voice,” he maintained, “will allow the EU to put more pressure on the [international] discussions [for tax reform] and better defend our interests.”[15] His considerable dissatisfaction that just three Member States blocked the proposal explains why the Commission, backed by the largest and most influential EU Member States, felt vindicated in seeking to eliminate tax unanimity.

Fueled by the politically salient DST failure, in 2019, the Commission formally proposed eliminating the tax veto. It advocated applying the never-before-used provisions in the Treaty on European Union dubbed the “Passerelle Clauses” to effectuate the transition. [16] Through the Clauses, the Commission would extend QMV, the standard EU voting procedure, to include taxation.[17] While an arduous process, the Commission’s tax proposals would enjoy a higher likelihood of success since legislators would no longer need to obtain unanimous consent to enact time-sensitive legislation. This could lead to more opportunities, in the words of Dombrovskis, to “strengthen the single market” and allow the Union a higher chance of “speaking with one voice” in global tax negotiations, as a stronger counterweight to the United States, both now and in the future.[18]

The transition would also expand the role of large Member States, such as Germany, France, and Italy, since QMV positively biases more populous countries.  Yet, the proposal threatens small countries, who see the veto as an essential protector of their national sovereignty.[19] While supporting most of the EU agenda, Denmark, for example, vetoed the DST and reacted skeptically at the prospect of relinquishing additional authority to Brussels.[20] Thus, the proposal raises important questions about the appropriate balance of power between large and small states and the extent of EU influence over tax policy. A dual challenge thus faces EU lawmakers of an inefficient framework that allows a single country to block an important measure and a delicate balance of power prone to upset were the European Union to eliminate one of the last remaining unanimous voting provisions.

The proposal to transition to QMV would improve EU legislative efficiency, increase uniform legislation, and allow the Union to present a more unified front in global negotiations. But, simultaneously, the proposal poses a legitimate tax sovereignty threat to smaller states.Given the population thresholds in QMV, loss of tax unanimity would allow large state coalitions to enact legislation more swiftly. This change would leave small states, even if united, powerless to block popular, yet harmful, legislation. Absent the ability to effectively protect national interests in the Council, loss of veto power could lead to deeper resentment of EU economic policies and undermine EU cohesion. By contrast, in maintaining the status quo, legislators will continue to block important proposals by veto that risk fragmentation of the single market; yet, the European Union would signal its commitment to protecting equally the national sovereignty of all Member States.
