Tax-based Own Resources as a Core Element of a Future-Oriented Design of the EU System of Own Resources
Margit Schratzenstaller, Austrian Institute of Economic Research (WIFO), Vienna, Austria.
This article is part of the Forum Looking at the EU Multiannual Financial Framework 2021-2027.
Member States' reactions to the proposal for the next Multiannual Financial Framework (MFF) that the European Commission presented in May 2018 have been dominated by a focus on two aspects: the overall size of the next EU budget; and national contributions EU Member States will have to expect, particularly considering the imminent exit of the United Kingdom (UK) as the third largest contributor to the EU budget. Thus, it is obvious that the net position approach – well-known from previous MFF negotiations – is also shaping the current debate. Member States primarily consider their individual net positions, i.e. the difference between their payments into the EU budget and the transfers they receive out of it, when determining the benefits derived from the EU (budget). Much less attention is paid to indirect benefits from EU membership and expenditures, which generally exceed Member States' contributions to the EU budget considerably.As pointed out by the final report of the High Level Group on Own Resources (HLGOR) chaired by Mario Monti, this net position thinking is one of the key obstacles to a fundamental reform of the structure of the EU's expenditures.
Long-term challenges for the European Union and European added value
There is a broad consensus among experts that the current structure of the EU budget is inadequate to cope with the long-term challenges confronting the EU including digitalisation, recent and imminent rounds of enlargement, structural problems of the southern countries, persisting regional divergences, demographic change, climate change and energy transition, digital change and (refugee) migration.Key EU initiatives and strategies, such as the Europe 2020 Strategy, the 2030 Agenda for Sustainable Development, the EU Action Plan for the Circular Economy, and the efforts to combat tax avoidance and evasion are insufficiently supported by the current MFF.
Obviously, the MFF's overall approach needs to consider which one of the five scenarios put forward in the European Commission's 'White Paper on the Future of Europe' will be pursued eventually.The European Commission addresses the implications of each of these five scenarios as they apply to: the policy priorities guiding the expenditure structure, the EU budget's overall volume, the shares of expenditure under the various headings of the MFF and the revenue system in its 'Reflection Paper on the Future of EU Finances' presented in mid-2017. Accordingly, the structure of expenditures and revenues remains more or less unchanged (although based on a considerably lower overall volume of the EU budget) in the 'Doing less together' scenario. In the other four scenarios however, the introduction of new own resources – or at least of other revenue sources – would be required as well as structural shifts in EU expenditure.
There are strong arguments for a fundamental reform of the MFF regardless of the envisaged future integration scenario.Such a fundamental reform should aim at creating higher European added value through the EU budget. While it is difficult to measure and quantify the exact European added value, it is generally created when EU level action results in a higher value than separate national actions. Therefore, the EU budget should focus on those policy areas in which uncoordinated actions at the Member State level would be insufficient due to free riding, coordination problems and cross-border issues, or on policy areas in which common European interests are at stake.
Options to create EU added value through reform of the EU own resources system
Such far-reaching reform aimed at reinforcing the European added value provided by the EU budget should not be restricted to EU expenditures but should also include its revenue system. The current EU system of own resources certainly has its merits: it provides steady, predictable and reliable revenues; it guarantees a balanced budget; and it allows Member States to freely decide about the distribution of the financial burden among individual taxpayers. Nonetheless, the current financing system has been attracting various criticisms over the last few decades. These relate to its complexity and lack of transparency, as well as the fact that the EU system of own resources does not contribute to central EU strategies and policies.
Figure 1 shows that over the last few decades, traditional 'true' own resources (i.e. sugar levies and customs) have been continually decreasing in importance, leaving national contributions (GNI- and VAT-based own resources) as the dominant revenue source for the EU.

Composition of EU own resources in the long-term
Source: Own calculations based on European Commission data; data 1995-2016 from European Commission: EU Budget 2017. Financial Report, 2018; data 1958-1994 from European Commission: EU Budget 2008. Financial Report, 2009.
In 2017, the VAT-based own resource accounted for 14.7% of overall own resources (down from 70.4% in 1990), while the share of the revenues from the GNI-based own resource has increased to more than two-thirds of total own resources. Thus, the share of GNI- and VAT-based own resources together increased from less than half of overall own resources at the end of the 1970s to about 83% in 2017. Traditional own resources, which had made up for about 67.5% in 1976, contributed a relatively meager 17.7%. Neither of these revenue sources has any bearing on key EU strategies and objectives.
Central EU policies aimed at improving economic, social and environmental sustainability could be supported by sustainability-oriented tax-based own resources partially replacing Member States' national contributions.Such taxes would directly promote certain objectives such as climate change goals in the case of environmental taxes. Moreover, the resulting decrease of national contributions would allow Member States to cut more harmful taxes at the national level, particularly high taxes on labour, which would imply a fiscally neutral yet sustainability-enhancing tax shift. To meet additional revenue needs e.g. to cover the Brexit gap or to expand the EU budget volume, tax-based own resources are preferable to raising national contributions.
Taxes that cannot be enforced effectively at the national level due to tax competition based on highly mobile tax bases and/or tax subjects are obvious candidates for sustainability-oriented tax-based own resources. The case for Pigovian taxes at the EU level is strengthened further if tax rates are set at sub-optimal levels due to cross-border externalities which are not considered by national governments.In addition, unilateral tax measures aimed at reducing cross-border externalities, e.g. externalities caused by emitting greenhouse gases, may alleviate the pressure on other countries to implement unilateral tax measures themselves as they can act as free-riders. Following the reasoning of Keen et al., it can be argued that revenues from taxes levied on tax bases characterised by international spillovers (e.g. CO2 emissions) should be used to finance a supranational budget that cannot be assigned to a specific country.
Table 1 contains several candidates for sustainability-oriented tax-based own resources: including taxes on flight tickets, net wealth, nuclear power and financial transactions; a share of a common (consolidated) corporate tax base and a supplement on national fuel tax rates; and revenues from a border carbon adjustment for the European Emission Trading System.

Several of these options are also addressed in the Final Report of the HLGOR. According to this report, a basket of tax-based own resources is preferable to introducing one single tax-based own resource.In such a 'basket solution', country-specific differences of individual taxes would cancel each other out in some cases; the need for correction mechanisms would therefore be less urgent. Moreover, such a broad-based approach to the introduction of tax-based own resources would stabilise overall revenues.
The implementation of tax-based own resources does not necessarily require own genuine taxation power, i.e. full legislative and revenue authority for the EU, and is therefore also compatible with the current legal and institutional set-up (i.e. the 'carrying on' scenario). Under this scenario, tax-based own resources could be introduced based on some kind of remittance system, with Member States' tax administrations collecting revenue and transferring it (partially) to the EU budget. A uniform call-up rate as a percentage of Member States' GNI could be fixed for a basket of several tax-based own resources. This call-up rate could be applied to Member States' overall revenue from tax-based own resources to determine the amount to be remitted to the EU budget. The remaining revenue would go into national budgets. Such a pragmatic approach would not restrict national tax sovereignty and could thus be more acceptable to (the overwhelming majority of) Member States' governments and parliaments who are reluctant to give up some of their taxation powers.
Sustainability-oriented tax-based own resources would do more than just help to close the existing sustainability gaps in EU taxation. Due to their sustainability-promoting effects, they are likely to be socially and politically more acceptable than other tax-based own resources which are pure revenue-raising instruments lacking any desirable steering effects and may even be perceived as unfair, as for example the VAT-based own resource suggested by Cipriani.
Not least the sustainability-oriented tax-based own resources suggested above have the potential to alleviate the net position problem: by loosening the direct link between national transfers to, and payments received from, the EU budget. There is no, or only a rather loose, link between the activities and tax bases affected by the taxes in question and the tax-collecting Member States, so that revenues can hardly be assigned to individual Member States. Moreover, these taxes are somewhat 'additional', as they can be enforced only insufficiently, or not at all, at the national level. This additionality has two further advantages: Firstly, there would be no, or very few, Member States already levying the respective tax at the national level, so that neither significant resistance nor demands to be compensated for the foregone revenue would be expected.Secondly, issues of vertical tax competition and of tax-base co-occupation through exploiting certain tax bases simultaneously at the level of Member States and the EU would be of limited relevance.
Fears expressed from a political economy perspective that tax coordination would be equivalent to forming a tax cartel of national governments at the expense of citizens appear unfounded:there is well-documented evidence of undertaxation in the areas addressed by our sustainability-oriented tax-based own resources. Therefore, the beneficial effects of tax coordination can be expected to exceed the potential welfare-enhancing effects of tax competition.
The European Commission's reform proposal for the EU system of own resources
The proposal for the MFF 2021-2027 launched by the European Commission on 2 May 2018 in fact aims at enhancing the EU budget's European added value.To address the long-term challenges the EU is facing, the European Commission proposes a combination of expanding the EU budget volume and shifting the structure of EU expenditures as well as revenues.
The European Commission suggests several structural reforms for the EU system of own resources which are based on the recommendations derived by the HLGOR.These reforms include a simplification of the system of own resources. Along with the elimination of the UK rebate, which will become obsolete after Brexit, all other rebates for certain net contributing countries will be phased out. Moreover, the calculation method for the VAT-based own resource would be simplified. These welcomed proposals will make the own resources system less complicated and more transparent.
In addition, the European Commission's plans foresee a diversification of own resources: new 'true' own resources will replace or complement, respectively, the EU's current funding sources. Concretely, the European Commission proposes to channel 20% of the revenues from auctioning emission trading certificates, the revenues from a three percent common consolidated corporate tax base (CCCTB), and the revenues from a tax of 80 euro cents per kilogram of non-recycled plastic waste into the EU budget. These new own resources are expected to raise the share of overall EU revenues to 12% in the future, thereby reducing the share of national contributions from over 80% to 71% by 2027.
Indeed, the three new own resources suggested by the European Commission appear to be 'natural' true own resources for the EU. The plastic tax due to the cross-border nature of the environmental damage associated with plastic waste and the use of fossil fuels for plastic production. The other two options – i.e. a share of the revenues from auctioning off emission trading certificates and a share in a harmonized corporate tax base – are directly connected with EU policies to cope with important European challenges transgressing national borders. However, the financial contribution of these new own resources would be rather moderate in quantitative terms. Therefore, the introduction of further tax-based own resources beyond the European Commission's proposals, along the lines presented above, can be expected to create considerable additional European added value.
Conclusions and outlook
A central prerequisite for the implementation of tax-based own resources is a parallel far-reaching shift in the EU's spending priorities.Otherwise, the introduction of tax-based own resources may rather reinforce Euroscepticism in the EU, as they are much more visible for citizens than the current revenue sources.
Despite some long-term shifts in EU expenditure, the EU budget still creates too little European added value.The current MFF is still dominated by the common agricultural policy (CAP) which makes up almost 40% of overall EU expenditures. Cohesion policy consumes another 34% of EU spending, while a still moderate share of 7.3% is dedicated to Horizon 2020, the European research framework programme and another two percent is spent on trans-border infrastructure (Connecting Europe Facility). Only about two percent of overall expenditure is dedicated to development assistance within the regular EU budget, and Schengen-related spending (asylum, migration, borders and internal security) amounts to only one percent of the current MFF.
The recent proposal by the European Commission aims at a rather moderate restructuring of EU expenditures.The share of agricultural and of cohesion expenditures (regional and social funds) will be reduced to 29% of overall expenditures respectively. The share of the research framework programme Horizon would increase from 7.3% to 7.6% of overall expenditures, while the share dedicated to cross-border infrastructure (Connecting Europe Facility) would stagnate at about two percent. The largest increases are foreseen for the areas of migration, asylum, border management, defence and external relations, which together will more than double their share in overall expenditures from currently 7.7% to 15.5%.
Ultimately EU Member States need to overcome the net position thinking currently blocking the route to an EU budget that is adequate in structure and size to meet future challenges. This again requires the acknowledgment of the manifold benefits provided to all EU countries by their EU membership. Substituting a major share of national contributions by sustainability-oriented tax-based own resources may act as a catalyst to secure net contributors' agreement to maintain or even increase the current spending level in exchange for a far-reaching reform of EU expenditure to enhance European added value. Therefore, one crucial success factor for a future-oriented reform of EU finances is to understand the need for package solutions,comprising the expenditure as well as the revenue side of the EU budget. An obvious example is the concentration of cohesion funds on 'poorer' Member States. Currently, the majority of the EU Member States strongly object to any tax coordination as they regard the option of tax cuts or lower tax levels as one of the few instruments available to them to secure their competitiveness. Another package deal may include the introduction of carbon levies and decarbonisation measures in heavily affected countries, possibly contained within agricultural or cohesion funds or expenditure on cross-border infrastructure.
