Do you have an owner-occupied property? And is this your main residence? Then you may deduct certain costs, such as mortgage interest from your income. You must add an amount to your income in Box 1. This amount is known as the notional rental value. It is a percentage of the so-called 'WOZ value' of your owner-occupied property, i.e. the value under the Valuation of Immovable Property Act (Wet waardering onroerende zaken, or WOZ). This value is determined by the authorities of the Dutch municipality in which the property is situated. Is your property outside the Netherlands? Then use the market value. Use, for example, a valuation report. For 2009, use the value on 1 January 2008.
The notional rental value only applies to the property that serves as the principal residence. Second homes – e.g., a holiday home – and other immovable property fall in Box 3.
| WOZ value | Percentage for nominal rental value |
|---|---|
| € 0 - € 12,500 | - |
| € 12,501 - € 25,000 | 0.20% |
| € 25,001 - € 50,000 | 0.30% |
| € 50,001 - € 75,000 | 0.40% |
| € 75,001 - € 1,000,000 | 0.55% |
| € 1,000,001 and more | € 5,500 increased by 0.55% of the WOZ value above € 1,000,000. |
Did you have an owner-occupied property for part of the year? Then use a part of the notional rental value that is in proportion to the time you had an owner-occupied property. For example: you had an owner-occupied property for six months of the year. You then report half the notional rental value.
Do you have an owner-occupied property outside the Netherlands? Then you only need to report this in your tax return when you choose for treatment as a non-resident tax payer. Can your partner deduct costs of the owner-occupied property in the country in which you live? Then you cannot deduct these costs in the Netherlands.]
