How many years of residence do I need for a Dutch permanent residence permit?

The core requirement for Dutch permanent residence is five uninterrupted years of legal residence with the Netherlands as your main home. During those five years you must have always kept a valid residence permit, extended it in time, and continued to meet its conditions.

Gaps, late extensions, or periods where you no longer met your permit's requirements can break the continuous-residence clock. Because the five years must be unbroken, it is worth keeping careful records of your permits and renewal dates throughout your stay.
