Lower House puts box 3 plan under further pressure
During the financial debate, parties demand relief for small savers and investors, while the cabinet prepares a new system.
The Lower House put the cabinet under renewed pressure over box 3 on Wednesday. In the debate on the 2027 budget, there was widespread criticism of the burden on small savers and investors, but no fully developed alternative is yet available.
Box 3 is one of the main points of contention during the General Financial Considerations. MPs are discussing the financial plans for 2027, including the letter on box 3 that Minister of Finance Eelco Heinen and State Secretary Eugène Heijnen sent to the House on 15 September. The debate will continue on Thursday.
The cabinet ultimately wants to switch to a system that taxes the actual return achieved on assets. When presenting the Budget Memorandum, Minister Heinen said the cabinet wanted to bring forward a definitive proposal for a capital gains tax quickly. That proposal is not yet law and still has to be considered by parliament.
The discussion is mainly about the period until the new system comes into force. The current arrangement uses assumed returns, while savers and investors may in reality have different returns. The government has therefore established a rebuttal procedure and a compensation operation for taxpayers who, according to the Supreme Court, have paid too much tax.
Opposition parties and some coalition parties want the burden on small asset holders to be reduced in the short term. They point out that a modest savings account or small portfolio is not the same as substantial investment assets. At the same time, supporters of a broad levy warn that exceptions make the arrangement more complicated and could create new borderline cases.
The cabinet must also make a budgetary choice. Lower taxes on savings and investments mean less revenue or a higher bill for other groups, unless spending is cut elsewhere. The parliamentary letter on box 3 therefore also contains tables showing budgetary consequences and possible funding options.
The process has not yet been completed. On Thursday, the cabinet will respond, after which the concrete bills must be worked out. Until then, the only certainty is that political support for the current transitional solution is fragile; there is still no agreement on the precise form or timetable of the new system.
One story, several perspectives
What is established
- The financial debate on box 3 takes place on 30 September and 1 October 2026.
- The cabinet is working on a system intended to tax actual returns on assets.
- The current arrangement and the compensation operation are still under parliamentary consideration.
- The precise transitional rules and funding of possible tax relief have not yet been finalised.
Left
Arguments The levy should immediately spare small savers and investors, because wealth is unevenly distributed and taxation based on assumed returns can affect people without them having actually achieved a return. A higher bill for substantial wealth or other forms of capital would then be more appropriate.
Values Equality, security of existence and ability to pay according to wealth.
Consequences A targeted exemption or higher threshold could help households quickly, but could make the arrangement more complicated and reduce revenue.
Centre
Arguments The institutional solution is an workable system based on actual returns, with transitional rules that limit legal risks. Changes must be budgeted for and remain understandable to taxpayers.
Values Legal certainty, practicability and budgetary discipline.
Consequences A gradual introduction would prevent new compensation operations, but would mean that some groups have to wait longer for relief.
Right
Arguments The government should not discourage saving and investment. Small investors and entrepreneurs should not receive the same tax treatment as substantial asset holders who can achieve returns structurally.
Values Property, economic growth and an attractive investment climate.
Consequences Lower burdens could stimulate investment, but could reduce tax revenue and increase inequality if mainly wealthy people benefit.
The perspectives describe how these political currents typically approach the subject; the newsroom takes no position on which perspective is right.

Editor's note
It is certain that box 3 is part of the parliamentary financial debate and that the cabinet wants to tax actual returns. The final design, transitional rules and funding of any tax relief remain uncertain.Sources
