Limitation of adjustment factor
In 2026, only 46.2% of the adjustment factor (tabelcorrectiefactor) in income tax will be applied. This means that in 2026, less than half of inflation will be offset by an increase in income tax brackets and income tax credits.
Startups and scale-ups
A special scheme will be introduced in wage tax that narrows the tax base of income from stock options for employees of startups and scale-ups to 65% and extends to the box 1 income tax. This makes the effective tax rate similar to a situation where stock options would have been taxed in box 2.
Business discontinuation relief and co-working partner’s relief abolished
The business discontinuation relief in income tax will be reduced by 75% from 2027 onwards, down to an amount of EUR 908 (2025: EUR 3,630). In 2030, the entire scheme will be abolished. An evaluation showing the scheme no longer to serve a legitimate purpose inspired the legislator to abolish it. The co-working partner’s relief in income tax is being phased out for the same reason. First, the relief rates will be greatly reduced in 2027, after which the entire scheme will be terminated in 2030. The proceeds will be used to finance the new tax scheme for startups and scale-ups.
New box 3 regime delayed
The introduction of the new box 3 regime, in which taxation is based on the actual return achieved, will be delayed to 2028. On top of that, owner-occupiers’ use of their own property can only be taken into account in the box 3 rebuttal scheme from 2026 onwards. The budgetary loss will be absorbed by increasing the flat rate for other assets in box 3 by 1.78 percentage point from 2026 and reducing the tax-free wealth threshold to EUR 51,396.
Employment tax credit
From 2027, the employment tax credit (arbeidskorting) can no longer be applied to social security benefits that are paid through the employer’s payroll, as was already the case with benefits paid by a benefits agency. The proceeds will be used to contribute to funding of the legal aid system.
Increase in Invalidity Insurance Fund contributions
Contributions to the Invalidity Insurance Fund (Arbeidsongeschiktheidsfonds, Aof) will be structurally increased by EUR 225 million from 2026 onwards. Moreover, to ensure that the difference between the two contribution rates remains at the desired level, in 2026 and 2027 the low Invalidity Insurance Fund contributions for small employers will successively decrease by 0.21 and 0.23 percentage points, respectively, while the high contributions (for medium-sized and large employers) will increase by 0.03% and 0.04%, respectively.
Bicycle scheme clarified
An addition to income tax currently applies for the provision of regular and electric bicycles that are also available for private use. The Spring Memorandum now clarifies that this addition does not apply to bicycles that are used for commuting to and from work, but are generally not taken home.
