In a significant shift to its taxation policy, Belgium will begin imposing a 10% capital gains tax on financial assets including shares and cryptocurrencies starting January 2026. The reform aims to broaden the country’s tax base, fund pension reform, support migration enforcement, and bolster defense spending—all while protecting smaller investors through targeted exemptions.

I. A Major Shift in Belgian Tax Policy
1. Capital Gains Tax to Be Introduced in 2026
Belgium is preparing to implement a capital gains tax on financial assets such as stocks and cryptocurrencies, marking a significant departure from its long-standing tax practices. This move, announced by Finance Minister Jan Jambon, will bring Belgium in line with other European nations that already tax capital gains from individual investors.
2. Belgium Ends Its Tax Exception
Until now, Belgium was one of the few European countries that did not impose capital gains taxes on most financial asset profits earned by individuals. Despite its reputation for having one of the highest income tax rates—up to 50%—capital gains remained largely untouched. The new 10% tax represents a recalibration of the system, ensuring that returns from financial investments contribute to the country’s fiscal needs.
II. Key Features of the New Capital Gains Regime
1. Tax Applies to Realised Gains Only
The tax will only apply to capital gains that are realized, such as when assets are sold. It will not affect any profits accumulated before the new law takes effect. The government confirmed that the policy will be implemented starting January 1, 2026, giving investors ample time to adjust.
2. Annual Exemptions to Protect Smaller Investors
To cushion the impact on everyday investors, the tax system includes an annual exemption. Each individual will be able to earn up to €10,000 in capital gains per year without being taxed. For those who have not recorded any capital gains in the previous five years, the exemption increases to €15,000 annually. This provision is designed to safeguard long-term, smaller investors and encourage consistent, patient investing.
3. Special Provisions for Significant Shareholders
Investors holding at least a 20% stake in any company will be subject to a separate, progressive tax structure. These larger stakeholders will benefit from a significant exemption of €1 million every five years. This tiered approach reflects the government’s intent to balance tax equity with economic encouragement for major business contributors.
III. Strategic Goals Behind the Policy Change
1. Funding National Reforms
Finance Minister Jambon emphasized that the new tax revenue will help finance essential reforms. Among the priorities are restructuring the national pension system, enhancing border and immigration controls, and boosting defense spending. The shift reflects the government’s broader strategy to reallocate tax revenue from labor toward capital, promoting a more balanced and sustainable fiscal framework.
2. Aligning With EU Norms
The introduction of this tax also closes a policy gap that had set Belgium apart from its neighbors. Most European Union member states already impose some form of capital gains tax, particularly on wealth generated through financial instruments. By adopting a similar approach, Belgium strengthens its economic alignment with the broader EU tax landscape and removes inconsistencies that previously encouraged tax avoidance or capital outflows.
3. Exemptions for Pension and Insurance Products
To encourage retirement planning and long-term security, the government has decided to exempt pension savings products and group insurance plans from the new capital gains tax. This move protects citizens’ long-term financial planning and ensures that the new policy doesn’t undermine retirement incentives.
IV. Public and Investor Reactions
1. Balanced Reception Expected
While any new tax policy can be met with resistance, early responses suggest that the government’s effort to shield smaller investors will likely soften opposition. The exemptions are particularly targeted to avoid penalizing middle-class citizens who engage in modest investment activities.
2. Market Stability Unlikely to Be Disrupted
Given that the tax only applies to gains realized after 2026, financial markets are expected to absorb the change gradually. Investors now have a clear timeline to restructure their portfolios if needed, and the relatively low tax rate of 10% is unlikely to spark significant capital flight.
3. Encouraging Responsible Investment Behavior
The exemption thresholds and progressive tax scheme may also promote more deliberate, long-term investment behaviors, particularly among smaller investors. By rewarding patience and discouraging excessive short-term speculation, the government aims to foster a healthier financial market environment.
Conclusion
Belgium’s decision to introduce a capital gains tax marks a pivotal moment in its economic policy. By taxing profits from financial assets while protecting modest investors and retirement plans, the government seeks to raise funds for pressing reforms and achieve greater alignment with EU practices. With implementation set for January 2026, the measure reflects a calculated move toward fiscal sustainability, equity, and strategic investment in national priorities.
