The Dutch Liberal Party (VVD) is advocating for the introduction of a capital gains tax on Box 3 assets as early as 2028, a move that has exposed divisions within the ruling coalition, according to Accountancy Vanmorgen.
The proposal, which would shift the tax base from notional returns to actual realized gains on investments and savings, has met resistance from other coalition partners who favor a more gradual transition. Reports from NOS indicate that the disagreement over the implementation timeline is escalating, with the coalition heading toward a potential conflict on the matter.
The debate centers on the future of Box 3, the Dutch tax category for income from savings and investments. Currently, taxpayers are taxed on assumed returns rather than actual profits. The proposed capital gains tax would instead levy charges on real investment profits, a fundamental change that has proven politically sensitive. NRC notes that the wealth tax has long been a contentious issue in Dutch politics, with repeated delays and legal challenges complicating reform efforts.
A key sticking point, as explained by AD.nl, is that under the proposed system, investors could face tax liabilities on gains that have not yet been realized—meaning they might owe money on paper profits that could later evaporate. This technical complexity adds to the political friction.
The VVD's insistence on a 2028 start date contrasts with the more cautious approach favored by other parties in the coalition, which prefer additional time for implementation and legal preparation. The disagreement threatens to stall broader tax reform efforts.
What to watch next: Whether coalition partners can bridge their differences or whether the dispute forces a compromise that pushes the timeline further out.
