Why do I get a provisional tax assessment, unsolicited?
In some cases, you receive a provisional tax assessment, while you did not ask for one. How is this possible? Well, the Belastingdienst becomes a better predictor of the amount of tax you have to pay. So they already send you a provisional tax assessment if they have a good prediction of the amount of tax you have to pay in a year.
This avoids that you have to pay the taxes at once, and it avoids that the Belastingdienst has to pay you at once. If the personal details are not correct, you can change them in ‘Mijn Belastingdienst’: ‘Verzoek of wijziging voorlopige aanslag’. You can choose to pay the amount at once or to pay it in 11 installments.
