The tax return, which must be fulfilled regularly every year in the Netherlands, is of great importance for both employees and self-employed persons. For 2025, you can find all the details you need to know about the individual tax return process and the current regulations in this guide.
1. What is a Tax Declaration?
The individual tax return is an official document in which the income received during the year, deductions made, tax deductions and taxes paid are reported in detail. The tax system in the Netherlands is categorised according to the types of income into "Box 1" (earnings and pension income, salaries, self-employment earnings), "Box 2" (significant share ownership) and "Box 3" (savings, investments and savings). It is of great importance for the tax office (Belastingdienst) that each individual correctly declares their income in these boxes.
2. Important Dates and Required Documents for 2025
Important Dates
- Beginning of Declaration: You can usually start filing your declaration via the online system at the beginning of March.
