Want to file a tax return together?

If you have a tax partner, why not file a tax return together? This saves time and prevents errors. It also makes it easier to favourably divide your income and deductible items.

How can I file a tax return together with my partner?

If you want to file a tax return together with your partner, indicate this on your income tax return. Answer 'ja' (yes) to the question: 'Wilt u samen aangifte doen?' (Do you want to file a tax return together?).

By what date do you need my income tax return?

We must have received your income tax return before 1 May in the relevant tax year if you have received an invitation from us. If you file a tax return before 1 April, you will be notified before 1 July. Officially, we have 3 years to process your tax return.

Do I have to file an income tax return?

If you have not received an invitation, you can still file an income tax return up to 5 years after the end of the tax year in question.
