Netherlands-Morocco Double Taxation: Guide for MRE in the Netherlands

The 1977 Netherlands-Morocco convention distributes taxing rights by income category. Real estate income is taxed in Morocco (Article 6). Salaries are taxed in the Netherlands (Article 15). Dividends are subject to withholding at source in Morocco of max 15% (10% if shareholding > 25%) and can be taxed in the Netherlands with credit. Private pensions are taxed in the Netherlands, Moroccan public pensions in Morocco. To eliminate double taxation, the Netherlands primarily uses the exemption with progression method (Article 22).

Yes, even if they are exempt from direct taxation in the Netherlands. Under the convention, rents on properties located in Morocco are taxable in Morocco only. But in the Netherlands, you must still declare this income in your Aangifte for two reasons: 1) the progression calculation (this income can push up your rate on Dutch income); 2) Moroccan real estate is included in box 3 calculation at its fair market value. Omission of this declaration is penalized even if no Dutch tax is ultimately owed.

Exemption with progression means that your Moroccan income covered by the convention is exempt from tax in the Netherlands (exemption), but its amount is taken into account to determine the tax rate applicable to your Dutch income (progression). For example: you earn €40,000 in the Netherlands (rate 37%) and receive €10,000 in Moroccan rents (exempt). The Dutch rate is calculated on €50,000 (37%+), but applies only to the €40,000 Dutch income. In practice, Moroccan rents can slightly increase tax on your Dutch income.

Under the NL-Morocco convention, private pensions (such as CNSS, occupational scheme) received by a Dutch tax resident are taxable in the Netherlands. They must be declared in the Aangifte. If the CNSS withholds Moroccan tax on your pension, you can claim a tax credit to avoid actual double taxation. Moroccan public pensions (civil servants) remain exclusively taxable in Morocco. It is important to distinguish your type of pension to apply the correct treaty rule.

The 30% ruling (expat tax facility) is a Dutch tax benefit for employees recruited from abroad with scarce skills on the Dutch market. It allows receiving 30% of gross salary as a tax-free allowance for up to 5 years. 2026 conditions: have been recruited from abroad (or from Morocco), lived more than 150 km from the Netherlands before employment, possess specific expertise, minimum taxable salary of €46,107/year (or €35,048 for graduates under 30). Note: since 2024, the rate has been progressively reduced.

If you omitted to declare Moroccan income in past Dutch returns, you can regularize your situation by filing an amended return (herziene aangifte) or contacting the Belastingdienst to make a voluntary disclosure. Spontaneous regularization (inkeer) is generally treated more favorably: penalties are reduced or waived if you come forward before an official investigation. The Belastingdienst has automatic information exchange agreements with Morocco, so proactive regularization is strongly recommended.

Capital gains from the sale of real estate located in Morocco are, under the NL-Morocco convention, taxable in Morocco (Article 13 on capital gains). They are therefore not taxed in the Netherlands but must still be mentioned in the Dutch return for the progression calculation. In Morocco, real estate capital gains are subject to income tax at a rate of 20% on the net gain (sale value - indexed acquisition value - costs), with exemption if the property was the main residence for more than 6 years.
