What are the deadlines for income tax returns in the Netherlands?
The fiscal year runs from 1 January to 31 December in the Netherlands. You always file your income tax returns for the previous year. Hence, at the beginning of 2023, you file for 2022’s taxes. The deadline for submitting the forms is 1 May unless you request an extension. You can do this by contacting the Belastingdienst (click on Uitstel aanvragen). However, in many cases, you’ll receive some money back, so why procrastinate?
You can submit the tax return from 1 March, which leaves you a window of two months. If you submit your tax declaration before 1 April, you’ll receive a message by 1 July about whether you’ll get some money back. Make sure you meet the deadlines, as otherwise, you’ll have to pay a fine.
