Eigenwoningforfait Calculator 2026
Enter your postcode and house number to look up your home's official WOZ value and calculate your 2026 eigenwoningforfait (owner-occupied home allowance) in the Netherlands (Nederland). No need to dig out your WOZ-beschikking or look up the percentage band yourself.
What the eigenwoningforfait is
The eigenwoningforfait is a notional rental value the Belastingdienst adds to your taxable Box 1 income for owning and living in your own home. It is a percentage of your home's WOZ value, set nationally every year. If you have a mortgage, your deductible mortgage interest (hypotheekrenteaftrek) is netted against it.
2026 rates by WOZ value
- Up to €12,500: 0%
- €12,500 to €75,000: 0.10% to 0.25%, stepped
- €75,000 to €1,350,000: 0.35% (most homes)
- Above €1,350,000: €4,725 plus 2.35% of the excess
Example: a home with a WOZ value of €400,000 falls in the 0.35% band, giving an eigenwoningforfait of €1,400 a year.
Not the same as OZB
OZB (onroerendezaakbelasting) is the municipal property tax you pay in cash, with a rate set by each municipality. The eigenwoningforfait is not paid directly: it raises your taxable income in your annual tax return.
Frequently asked questions
Where does the WOZ value come from?
From the Kadaster WOZ-waardeloket, the same public source your municipality's WOZ-beschikking is built from.
Why is my eigenwoningforfait not exactly 0.35% of my WOZ value?
0.35% only applies to the most common band, roughly €75,000 to €1,350,000. Below that the rate is lower in steps down to 0%, and above €1,350,000 a fixed base plus 2.35% of the excess applies.
