Is the Netherlands’ 36% Wealth Tax Coming to Your Country Next?

In early 2026, the Dutch House of Representatives approved a major reform to its investment tax system.

The proposal aims to tax annual investment returns more directly, including certain unrealised gains. The effective rate is around 36 percent. The law still requires final approval and is expected to take effect in 2028. Even so, the signal has travelled quickly across Europe and beyond.

For African CFOs and senior executives with global assets, this is not simply a European tax story. It is a reminder that fiscal policy in developed economies is evolving.

Governments are looking for stable ways to tax accumulated wealth, not just income. When one advanced economy tests a new model, others tend to observe closely. The implications extend well beyond one country.

Many executives assume that tax rules affecting private capital remain stable once a country becomes wealthy. Recent developments suggest otherwise. The Netherlands is one of the richest economies in the European Union.

Yet it is still redesigning how it taxes investment returns. The lesson is not that every country will follow. The lesson is that policy direction can change even in stable jurisdictions.

Why This Matters for Globally Mobile Executives

Across Europe and the United Kingdom, public finances are under pressure.

Ageing populations, rising healthcare costs, and long term debt obligations are reshaping tax debates. Policymakers are increasingly focused on wealth and capital as revenue sources. This does not mean that every country will introduce a tax on unrealised gains. It does mean that the direction of discussion is shifting.

For African executives who have worked internationally, accumulated assets abroad, or plan to retire outside their home country, residency decisions are becoming more strategic. Retirement is no longer only a lifestyle choice. It is a jurisdictional choice. Where you live can influence how your global portfolio is taxed for decades.

Many African CFOs and founders have diversified holdings across continents. Some hold property in Europe, investment accounts in the UK, and business interests across Africa. In that context, tax residency is not a technical detail. It is a central planning variable. Reviewing it ten years before retirement is far easier than attempting to restructure in the final year of work.

The Shift From Event-Based Taxation to Ongoing Taxation

Historically, investors were taxed mainly when gains were realised. A sale triggered the tax event. This allowed long term compounding to operate largely undisturbed. The emerging model in some countries is different. Governments are exploring ways to tax annual returns more consistently, including changes in asset value. This approach reduces reliance on one time events and increases predictable revenue.

This shift has practical consequences. When taxation is linked to annual asset value, liquidity planning becomes more important. Investors may need to consider how to meet tax obligations without triggering forced sales. For executives planning retirement, this adds another layer to portfolio management and jurisdictional planning.

None of this requires immediate action. It does suggest that long term residency strategy deserves attention. The most effective decisions are made calmly and early. Executives who wait until retirement often find that options are narrower and timelines tighter.

Why Mauritius is Entering the Conversation

As global tax frameworks evolve, internationally mobile investors are reviewing jurisdictions that offer clarity and predictability. Mauritius has increasingly appeared in these conversations. It is politically stable, legally transparent, and operates a territorial style tax system. Capital gains on most investments are not taxed. There is no annual wealth tax on global assets.

For African executives, Mauritius offers an additional advantage. It is geographically and culturally connected to the continent. It operates in English and French. Its financial services sector is well developed. It is also a recognised hub for cross border investment into Africa. This combination makes it familiar territory for many decision makers.

Residency pathways are clearly defined. Individuals can qualify through property purchase, income thresholds, or investment. None of these routes should be approached hastily. They require planning and professional advice. What matters is that the framework is stable and transparent, allowing executives to evaluate options over several years.

Planning Windows and Timing Considerations

Residency planning is most effective when started well before retirement.

Property acquisition, tax residency changes, and asset restructuring all require time. Pension arrangements and corporate interests may need to be reviewed. Establishing a presence in a new jurisdiction gradually allows for smoother transitions and fewer surprises.

Executives often underestimate how long these processes take. A five to ten year horizon is ideal. It allows for exploratory visits, professional advice, and measured decisions. It also reduces the risk of reactive moves driven by sudden policy changes in home jurisdictions.

It is important to emphasise that Mauritius is not the right solution for everyone. Some individuals prefer to remain in Europe for family or healthcare reasons.

Others have business interests that tie them to specific countries. The objective is not to promote relocation. The objective is to encourage structured evaluation of long term residency strategy.

What Sophisticated Investors are Doing

Across Europe, the UK, and parts of Africa, many high net worth individuals are reviewing their residency assumptions. They are not rushing to relocate. They are gathering information. They are modelling tax outcomes under different scenarios. They are considering how their personal and corporate structures interact with potential retirement locations.

This approach reflects a broader shift in mindset. Residency is increasingly viewed as part of capital allocation strategy. Just as portfolios are diversified across asset classes and regions, residency can be diversified across time. Early preparation creates optionality. Optionality reduces stress.

For African executives with international exposure, Mauritius often appears on the shortlist. It offers a familiar legal environment, a predictable tax framework, and strong links to global markets. It also allows individuals to remain connected to African business interests while enjoying a stable retirement base.

Bottom Line For Decision Makers

The Netherlands' proposed tax reform highlights a broader trend. Developed economies are exploring new ways to tax accumulated wealth. Policies will vary across countries, but the direction is becoming clearer. For executives planning retirement within the next decade, now is a sensible time to review long term residency strategy.

Mauritius is not the answer for everyone. It is, however, a jurisdiction worth evaluating carefully. Early planning provides flexibility. Flexibility allows decisions to be made on your own terms. For globally mobile leaders, that may be the most valuable asset of all.
