Council of State Rejects 2028 Box 3 Tax Overhaul Plan
The Raad van State has issued a severe warning against the Dutch cabinet’s timeline to implement a new capital gains tax system in box 3 by 2028. The advisory body states that the rushed legislative process threatens both the quality of the tax proposal and the operational capacity of the Belastingdienst. The Raad van State does not object to the substance of taxing actual returns rather than fictitious yields, but strongly opposes the administrative rush and noted that the advisory board previously held grave reservations regarding earlier box 3 proposals.
PRO member of parliament Luc Stultiens criticized the legislative trajectory during a parliamentary debate, calling the hurried amendments a potential drama reminiscent of past administrative scandals. Reminding listeners of the severe lessons learned from the childcare benefits scandal, Stultiens warned that rushing these changes would create a disaster. NOS reported that the Raad van State does not object to the substance of taxing actual returns rather than fictitious yields, but strongly opposes the administrative rush.
Operational Capacity and Unclear Financial Coverage
According to an execution test conducted by the Belastingdienst, introducing the new rules by 2028 is entirely unfeasible given ongoing operational pressures and impending structural budget cuts, as noted by the Raad van State. The advisory board points out that a temporary hybrid model—shifting financial instruments to a capital gains system by 2028 while keeping real estate and startups under an accrual system until 2030—would require 252 fte of personnel capacity and approximately € 31 million in additional execution costs. Furthermore, the Raad van State called it incomprehensible that the cabinet has not clarified how it plans to cover declining tax revenues during the transition.
Parliamentary Scrutiny and Upcoming Votes
The cabinet’s minority coalition faces intense pressure ahead of upcoming parliamentary decisions, with the Tweede Kamer scheduled to debate the tax package and vote on November 12. To meet the 2028 target date, both the Tweede Kamer and the Eerste Kamer must approve the box 3 amendments before December 31. Minister Heinen has proposed lowering box 2 tax rates temporarily to encourage director-major shareholders to withdraw corporate profits sooner, helping fund the transition costs estimated at € 15 tot € 20 miljard. However, opposition parties including Pro and Volt have challenged these coverage mechanisms, leaving the cabinet without a guaranteed majority in either chamber.
Frequently Asked Questions About the Box 3 Tax Debate
What happens if the 2028 implementation date is dropped?
If the government follows the advice of the Raad van State to delay the reform, the current system of taxing fictitious returns with a counter-evidence regulation will remain in place through 2028 and 2029, allowing a single transition to a new system in 2030, as detailed by the Raad van State.
How does the government plan to pay for the transition costs?
The transition to taxing actual returns costs an estimated € 15 tot € 20 miljard in the initial years, and Minister Heinen proposed temporarily lowering box 2 rates to prompt business owners to draw out profits early, alongside utilizing funds previously reserved for box 3 legal restoration.
What are the critical legislative deadlines for the tax plan?
The Tweede Kamer holds its vote on the tax package on November 12, and the legislation must secure approval from both parliamentary chambers before December 31 if the 2028 timeline is to remain formally achievable.
