Dutch homeowners have access to some of Europe's most generous tax benefits—but only if you know how to use them. From mortgage interest deduction to eigenwoningforfait optimization, these legal strategies can save you €2,000-€8,000 annually.
Potential Annual Savings
- • Mortgage interest deduction: €2,000-€6,000/year
- • WOZ objection (if successful): €100-€500/year
- • Energy investment deduction: one-time €1,000-€3,000
- • Transfer tax exemption (under 35): up to €11,100 one-time
- • NHG interest rate reduction: €500-€1,500/year
1. Mortgage Interest Deduction (Hypotheekrenteaftrek)
How It Works
You can deduct mortgage interest from your taxable income in Box 1. The maximum deduction rate is 37.56% (2026). This applies for up to 30 years from the date of your first mortgage.
Example: €400k mortgage at 3.5%
Requirements
- • Must be owner-occupied (not rental)
- • Mortgage must be fully amortizing
- • Maximum 30-year deduction period
- • Only for primary residence
- • Must file annual tax return
2. Eigenwoningforfait (Imputed Rental Value)
The government adds a fictional rental income to your taxable income based on your WOZ value. In 2026, this is 0.35% of WOZ value. However, if your mortgage interest exceeds the eigenwoningforfait, you still get a net deduction.

4. WOZ Objection Strategy
If your WOZ value is too high, you're overpaying on property tax, water board charges, and eigenwoningforfait. Objecting is free and succeeds in roughly 30% of cases.
When to Object
- • You bought the property for less than WOZ value
- • Comparable properties have lower WOZ values
- • Property has defects not reflected in valuation
- • Neighborhood has deteriorated since reference date
Deadline: 6 weeks after receiving your WOZ beschikking (usually February-March).

SEEH (Insulation)
€500-€2,500For wall, floor, or roof insulation in existing homes.
