Cross-border taxation: key figures for non-residents
Living abroad while earning Dutch income creates complex tax obligations. Tax treaties between the Netherlands and your country of residence determine how income is taxed.
C-form
Required
Non-residents with Dutch income must file a C-form (aangifte buitenlandse belastingplicht) in the Netherlands.
Qualifying non-resident rule
90% threshold
If 90% or more of your worldwide income is taxed in the Netherlands, you may qualify for the same deductions as Dutch residents.
Tax treaties
100+ countries
The Netherlands has tax treaties with over 100 countries to prevent double taxation on the same income.
Dutch property income
Always taxed in NL
Rental income or gains from Dutch real estate are always taxable in the Netherlands, regardless of your residence.
Social security
Country-dependent
EU/EEA workers generally pay social contributions in the country of employment. A1 certificate may be required.
Filing deadline
1 May 2026
Non-residents must file before 1 May, same as residents. Extensions are possible upon request.

No matter your tax question, Jan de Belastingman is here for you. Don't see your question? Get in touch .
You use the C-form when you live outside the Netherlands all year but have Dutch income. This is different from moving during the year, which requires an M-form.
If you live outside the Netherlands, you must declare Dutch income such as salary from a Dutch employer, pension from the Netherlands, or rental income from Dutch real estate. Certain benefits also fall under this category.
Yes, absolutely. We work fully GDPR-compliant and use secure connections. Your data is stored encrypted and is only accessible to your assigned fiscal consultant.
Yes, completely. Online calculators give you rough estimates. We provide a complete tax declaration prepared by experienced fiscal consultants, manually checked, and filed with the Dutch tax authorities. Plus, we proactively look for deductions and benefits you might miss.
If more than 90% of your worldwide income is taxed in the Netherlands, you may qualify as a qualifying non-resident taxpayer. This entitles you to the same deductions and tax credits as a Dutch resident, such as mortgage interest deduction (maximum 37.48% in 2025), the general tax credit (maximum EUR 3,068 in 2025) and the labour tax credit (maximum EUR 5,599 in 2025). Our fiscal consultants assess whether you meet the 90% requirement.
As a cross-border worker, you deal with tax rules in two countries. The Netherlands has specific tax treaties with Belgium and Germany that determine where you pay tax. In many cases, you pay income tax in the country of employment (the Netherlands) and social contributions in your country of residence. We ensure you don't pay double tax and that all relevant arrangements are correctly applied.
The deadline for the income tax return is 1 May of the year following the tax year. You can request an extension until 1 September. Filing late without an extension risks a penalty of EUR 469. Jan de Belastingman monitors all deadlines and automatically requests extensions on your behalf if needed.
Yes, our fiscal consultants assist you in Dutch, English and German. All communication, draft reviews and documents can be handled in your preferred language. This makes the process significantly easier for cross-border workers from Belgium and Germany.
