Belgium Wealth Tax: Coalition Partners Clash Over Fortunes

A fierce fiscal debate has erupted within Belgium’s governing coalition, as centrist party Les Engagés proposes a progressive annual tax on financial wealth exceeding €500,000 — a move that has drawn sharp condemnation from its liberal coalition partner, the MR. The clash comes as the federal government grapples with a budget shortfall requiring between €7 billion and €14 billion in savings by 2029.

The Proposal

Les Engagés, led by President Yvan Verougstraete, is advocating for a 0.3% annual contribution on financial assets — including cash, stocks, and bonds — above €500,000, with the rate rising to 0.6% for wealth exceeding €3 million. Real estate property is excluded from the proposal. The party estimates the measure would target the wealthiest 5% of Belgians and generate approximately €2 billion annually, as reported by RTBF.

“We’ve asked efforts from job seekers, teachers, pensioners, and we will also ask those with the deepest pockets,” Verougstraete said in an interview with La Libre Belgique, according to Belga. He framed the proposal as a matter of intergenerational responsibility, warning that failing to act would mean “creating debts for our children.”

Fierce Opposition from MR

Georges-Louis Bouchez, president of the liberal MR party, responded with characteristic bluntness, calling the proposal a “rage taxatoire” (tax rage), “more radical than the communists,” and “economic folly.” In comments reported by 21news.be, Bouchez argued that “it’s the state that must slim down, not the pockets of those who create the country’s wealth.”

The MR’s opposition is rooted in concerns that a wealth tax would drive capital and entrepreneurs out of Belgium, discourage investment, and ultimately yield disappointing revenues — pointing to international examples where similar taxes were scaled back or abolished.

Coalition Tensions and Electoral Dynamics

The debate is particularly significant because Les Engagés and the MR are not only coalition partners in the federal “Arizona” government — alongside N-VA, Vooruit, and CD&V — but also fierce competitors for the same center-right electorate. Recent polling shows the two parties neck-and-neck, with Les Engagés siphoning voters from the MR. The wealth tax proposal enjoys broad public support, including among right-wing voters, according to La Libre Belgique.

This is not the first time the issue has surfaced. During the 2024 election campaign, Les Engagés proposed a broad tax reform including better taxation of capital, which the MR opposed under the slogan “50 nuances de gauche.” Once in government, Les Engagés shelved those promises. The current proposal marks an attempt to reclaim the mantle of fiscal justice.

Budgetary Context

The proposal arrives at a critical juncture. Belgium’s federal government faces a severe budget deficit, with estimates ranging from €7 billion (according to Finance Minister Van Peteghem) to as much as €14 billion (according to the National Bank governor). The €2 billion revenue target from the wealth tax would represent a significant portion of the required savings.

Broader European Context

Belgium currently has no net wealth tax. It levies a 0.15% annual tax on securities accounts exceeding €1 million — which has yielded declining revenues, from €470 million in 2021 to €362 million in 2023 — and recently introduced a 10% tax on capital gains on financial assets. Across Europe, only seven countries still tax wealth in some form, with most having abolished such taxes between 1992 and 2018 amid concerns about capital flight and administrative complexity. However, a recent RTBF analysis notes that 67% of Europeans support wealth taxation, and studies suggest the impact on capital flight may be limited.

What’s Next?

The coming budget negotiations will test whether the wealth tax proposal can survive coalition politics. Les Engagés may use it as a bargaining chip in broader fiscal discussions, while the MR’s firm opposition suggests the proposal faces an uphill battle. The outcome will signal whether Belgium joins the small group of European countries moving toward — rather than away from — wealth taxation, or whether the liberal vision of spending cuts prevails.

With public opinion firmly behind the idea and the budget crisis demanding tough choices, this debate is unlikely to fade quickly. All eyes are now on Prime Minister Bart De Wever’s government as it navigates one of its most significant internal tests since taking office.
