Can Bouchez block new taxes while Belgium finds €10 billion by 2029?
MR president Georges-Louis Bouchez ruled out additional taxes on 11 July after Belgium’s federal coalition agreed to find €10 billion by 2029, setting up a difficult autumn argument over spending, revenue and who should bear the adjustment.
The eventual mix of spending cuts, tax changes and reforms could affect household disposable income, benefits, healthcare, public employment and business costs. Delaying credible action would also leave more revenue going to interest payments rather than services or investment.
MR president rejected further tax increases in on 11 July, one day after ’s federal coalition agreed to find €10 billion by 2029—€2.3 billion more than the €7.7 billion minimum adjustment identified by the federal . Speaking before the Flemish Community celebration at Brussels City Hall, Bouchez said the government should not add another tax layer to Belgium’s already heavy fiscal “lasagne”, according to BX1 and La Libre Belgique. No detailed savings package has yet been agreed.
The intervention drew a clear liberal boundary around negotiations that are due to culminate in the autumn budget conclave. Bouchez’s Mouvement Réformateur wants the additional correction to come primarily from lower public expenditure and structural reforms, rather than a new levy on wealthy households or businesses. The distinction matters because €10 billion is not a small accounting adjustment: it is equivalent to roughly €830 for every Belgian resident, although the eventual measures will not be divided evenly and could be phased in over several years.
The government chose the larger figure after receiving a bleak assessment from the . Its 6 July report projected a €25.7 billion deficit for the federal administration and social security in 2026, equal to 3.9% of gross domestic product. Without corrective measures, that shortfall would rise to €44.5 billion, or 5.7% of GDP, by 2031. For all Belgian public authorities combined, debt was projected to climb from 107.9% of GDP in 2025 to 122.6% in 2031.
BX1 reported that Prime Minister ’s cabinet settled on €10 billion partly to act before higher debt-servicing costs risk feeding what officials call a snowball effect. The coalition intends to hold its conclave in late September and complete the budget by the second Tuesday of October, when De Wever is expected to deliver his federal policy statement to the Chamber. Until ministers identify individual measures, the €10 billion remains a target rather than a funded plan.
That uncertainty is the real business story. Cutting subsidies, departmental budgets, pensions or healthcare produces a different economic effect from raising consumption, property or capital taxes. Employers may welcome restraint on payroll charges but still lose public contracts or investment support. Workers may avoid a new deduction on their payslip yet face tighter benefits or more expensive public services. For households, the relevant question is therefore not simply whether a measure is called a tax, but how it changes disposable income, energy costs, transport, healthcare and job security.
enters the debate with little comfortable room on either side. The applies progressive personal-income-tax rates ranging from 25% to 50% for 2026 income, before municipal surcharges and social contributions. That supports Bouchez’s argument that labour is already heavily taxed. But refusing every new source of revenue narrows the menu of politically feasible measures and shifts more of the adjustment towards spending, tax exemptions or enforcement.
The adds another complication. Its May forecast put ’s overall deficit at 5.2% of GDP in 2026, unchanged from 2025, and expected debt to rise from 107.9% of GDP in 2025 to 112.8% in 2027. The Commission also noted that existing consolidation combines spending restraint with additional receipts from VAT, capital-gains taxation and financial-sector measures. In other words, the government is already using both sides of the ledger even as Bouchez seeks to prevent another tax layer.
The , the country’s central bank and a central economic stakeholder, forecast in June that growth would slow from about 1% in 2025 to 0.6% in 2026 while inflation averaged 3.4%. It expected public debt to approach 115% of GDP in 2028. That weak-growth setting makes the composition and timing of consolidation important: abrupt household tax increases could suppress consumption, while indiscriminate spending cuts could weaken demand, investment and essential services.
The political divide is consequently about distribution as much as arithmetic. MR argues that should reduce the state’s cost and preserve incentives to work and invest. Parties and constituencies favouring a broader contribution from high incomes, capital or corporate structures contend that an expenditure-only approach would place too much pressure on social protection and public services. The ’s structural analysis offers a third perspective: Belgium taxes labour heavily but also maintains numerous exemptions and tax-induced distortions, suggesting that shifting or simplifying taxation is not identical to increasing the total burden.
Bouchez’s declaration is therefore best understood as an opening veto, not the conclusion of the budget process. The coalition has agreed on the size and deadline of the correction but not its contents, annual distribution or household impact. Ministers will work on proposals from early September before the conclave. The points to watch are whether MR accepts the removal of existing tax advantages as something other than a new tax, how coalition partners protect their social and economic priorities, and whether the final package produces durable savings rather than one-off receipts. Until those choices are published and costed, no government party can say precisely who will pay for ’s €10 billion adjustment.
Impact
Regional — Although the decision is federal, its effects may differ sharply across Belgium because employment, income and reliance on public transfers vary between Flanders, Wallonia and Brussels.
International — Belgium’s budget path also matters at EU level because the European Commission monitors member-state economic and fiscal developments. The federal coalition’s ability to deliver its €10 billion objective by 2029 will shape how Belgium’s deficit and debt trajectory is assessed alongside the Commission’s forecasts. For EU institution staff in Brussels, the immediate decisions remain Belgian federal measures: the article identifies no new EU-level tax or direct change to EU employment conditions.
What it means for you
No additional tax or spending measure was created by Bouchez’s 11 July statement itself. Residents and employers should watch the federal autumn budget negotiations for concrete decisions affecting income tax, benefits, healthcare, public employment and business costs. For 2026 income, Belgium’s personal-income-tax brackets still range from 25% to 50%, before other applicable charges. The key deadline is 2029, but individual measures may be introduced earlier through annual budgets. Do not change tax or household planning solely on the €10 billion headline; check enacted measures and their effective dates.
Opposing perspectives
- MR and expenditure-first liberals
Bouchez and MR argue that Belgium already taxes work and economic activity heavily, so the €10 billion adjustment should come principally from reducing expenditure, improving administration and carrying out structural reforms. They present new taxes as harmful to employment, investment and the reward from working.
- Redistribution and public-service constituencies
Parties, trade-union constituencies and social organisations favouring a broader contribution from high incomes, capital or corporate structures argue that ruling out revenue measures in advance pushes an excessive share of the adjustment onto benefits, public employees and services used by lower- and middle-income households.
- European Commission structural view
The Commission identifies both unusually heavy taxation of labour and numerous exemptions and distortions elsewhere in the system. Its analysis supports reducing labour taxes, but says such relief needs financing through expenditure choices, narrower tax breaks or alternative revenues rather than unfunded cuts.
