The Lower House on Tuesday concluded its debate on box 3 and the 2027 Tax Plan, but the political uncertainty has not gone away. Minister Eelco Heinen says his proposal is legally sound and workable, while alternative funding measures, he argues, have insufficient support in the Senate.
The government wants to change the taxation of assets through an amended box 3 scheme. The timetable is tight: the Lower House will vote on Thursday on the 2027 Tax Plan and the accompanying bill on actual returns.
According to Heinen, the government proposal prevents a larger financial problem from arising. The minister points to the consequences of court rulings on the current wealth tax and the risk that billions in tax revenue will be missing each year as long as a new system is not in place.
The Lower House also considered alternative funding proposals on Tuesday. Heinen said they do not have a majority in the Senate. The government therefore remains dependent on support from parties outside the coalition, while several parliamentary groups have criticised how the burden is divided among savers, investors and the public purse.
The Council of State previously warned about the haste with which the new system is being introduced. Under the current timetable, the government wants the new scheme to take effect in 2028. The Senate committee has announced that it will consider the bill in two rounds and link the vote to the Tax Plan.
The outcome for taxpayers has not yet been settled. The debate is not only about the level of the tax, but also about legal certainty and the Tax Administration’s ability to implement it. The political question behind the deadline is therefore twofold: how quickly can a legally sound system be introduced, and who bears the cost for as long as that does not happen?

One story, several perspectives
What is established
- The debate on box 3 and the 2027 Tax Plan has concluded.
- The Lower House is considering the bill and the Tax Plan this week.
- The precise level of support in the Senate is not assured.
- The Council of State previously criticised the speed of the process.
Left
Arguments A fair tax on assets should prevent legal arbitrariness and align the burden more closely with people’s ability to pay. Temporary solutions should not primarily affect ordinary savers and tenants.
Values Equality, legal protection and solidarity.
Consequences A more carefully designed system could delay implementation, but this approach says it would prevent new legal proceedings and unequal treatment.
Centre
Arguments The government must provide legal certainty quickly, but only through a scheme that is workable and verifiable. Temporary funding may be necessary while a structural system is being prepared.
Values Administrative feasibility, legal certainty and budgetary discipline.
Consequences Compromises could secure support, but may make the scheme more complicated.
Right
Arguments The government should exercise restraint in taxing accumulated wealth and prevent entrepreneurs and investors from moving their money elsewhere. New burdens should not be introduced without a clear financial foundation.
Values Property, enterprise and limited government.
Consequences A lower or simpler tax could support investment, but might widen the gap in the budget.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.
