A general assistant
A voorlopige aanslag is a provisional tax assessment. Check the amount and the payment dates in the letter. If something looks wrong you may be able to object. For advice about your own situation, consult a tax professional.

This is an advance on your income tax, paid in monthly instalments. Its deadline is in your plan now, and I will remind you before it. If your income changes, adjust it in Mijn Belastingdienst so you do not pay too much.
