Dutch Government to Expand Wealth Tax to Thousands More Investors in 2028

2026-09-30 community

The Hague, Wednesday, 30 September 2026.
A planned 2028 Dutch wealth tax overhaul will target thousands more savers and investors than expected, as the government lowers tax-free limits to cover budget shortfalls.

A Shift in the Box 3 Paradigm

The roots of the current tax overhaul trace back to a landmark decision by the Dutch Supreme Court (Hoge Raad) on 24 December 2021, which ruled the previous Box 3 wealth tax system unconstitutional because it taxed fictitious rather than actual returns [8]. Since then, the Netherlands has operated under a transitional system, applying a 36% tax rate to deemed returns categorized by asset type [8]. Currently, approximately 2.5 million people in the Netherlands fall into the Box 3 tax bracket, which captures individuals with significant savings, stock or cryptocurrency portfolios, or secondary properties [1]. Under the newly proposed ‘Wet werkelijk rendement box 3’ (Actual Return Box 3 Act), the government intends to transition to a system taxing actual returns starting on 1 January 2028 [8].

Lowering the Thresholds to Fill the Deficit

According to political sources on 29 September 2026, the newly designed capital-gains tax structure is set to capture thousands more investors and savers than the current transitional regime [1]. To secure a broader political consensus and balance the budget, the cabinet reportedly scrapped planned social security cuts, shifting the fiscal burden onto asset owners [1]. Because the overhauled system is projected to initially raise less revenue than the current transitional framework, the government plans to plug the funding gap by lowering the tax-free return allowance from €1,800 to €1,000 [1], representing a sharp reduction of -44.444%. Consequently, everyday savers and retail investors will begin paying wealth taxes much sooner and at higher rates [1].

Impact on Startup Investors and Entrepreneurs

The restructuring also targets business owners and directors of private limited companies (BVs) [1]. Historically, shifting private wealth into a BV was a common strategy for Dutch entrepreneurs seeking to optimize their tax exposure and avoid high Box 3 levies [7]. Under the new measures, however, the maximum amount an entrepreneur can borrow from their own BV will be slashed from €500,000 to €100,000 [1]. While startup shares and real estate are expected to face a capital gains tax restricted to the moment of actual sale, other liquid investment assets are slated to be taxed annually on unrealized paper gains [7][8]. This dual approach could significantly alter the risk-reward calculations for early-stage angel investors and startup founders who rely on private capital deployment [GPT].

Political Friction and Legislative Hurdles

The proposed tax changes have met with immediate political friction [1]. Opposition parties such as GroenLinks-PvdA and Volt expressed deep skepticism, with calls for further negotiations, while JA21 labeled the funding mechanism ‘unacceptable’ due to its impact on smaller, non-professional investors [1]. Meanwhile, 50PLUS demanded clarity on how these adjustments will affect middle-class citizens, including police officers, nurses, and retirees [1]. Conversely, ChristenUnie leader Mirjam Bikker looked favorably upon the cabinet’s willingness to adjust the plans so that vulnerable households are spared from carrying the financial burden [1].

The Road to 2028 Implementation

Although the Tweede Kamer passed the underlying bill for the actual return system on 12 February 2026, its legislative progress stalled in the upper house when the Eerste Kamer postponed its vote on 30 June 2026 [8]. Senators from several parties, including JA21, SGP, 50PLUS, and BBB, criticized the cabinet for failing to make a definitive choice among various tax scenarios [6]. The Senate is demanding a formal meeting with the cabinet before proceeding, with critical debates scheduled in the Tweede Kamer for 6 and 7 October 2026 [6]. The cabinet is under immense pressure to finalize the Box 3 policy before Christmas 2026, as each year of delay in implementing the reform costs the Dutch treasury over €3 billion [6].
