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

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.
