The start of a new year brings tax season in the Netherlands. The fiscal year runs from January 1 to December 31, and from early February onwards, the Belastingdienst begins sending notifications for filing your Dutch income tax return.
Whether you’re a foreign employee, freelancer, director, or dealing with cross-border tax complexities, navigating Dutch income tax requirements can be challenging. Broadstreet specialises in expat tax returns and international tax matters, ensuring your return is filed correctly and on time.
Income tax deadlines in the Netherlands for the 2025 tax year
Key dates
- April 30, 2026 is the standard filing deadline.
- March 30, 2026 is the recommended date to file if you wish to receive your preliminary assessment before July 1.
- Extensions are available and we request them when needed to prevent penalties.
Tax assessment after filing your Dutch income tax return
Once your return is submitted, you will receive a preliminary tax assessment. This assessment is based on your filed return and has not yet been fully reviewed by the tax authorities.
Returns filed before April 1 generally receive a preliminary assessment before July 1.
Returns filed after April 1 are usually processed within 10 to 12 weeks.
Returns involving C or M forms may take up to 24 weeks to process.
After review, the Belastingdienst issues a final assessment. This can take up to three years.
Broadstreet monitors your file throughout this entire process and handles all correspondence with the tax authorities on your behalf.
