  • Technical problems in MyMinfin - deadline postponed till 31st August 2025

    There are currently technical problems when sending a tax return on behalf of a deceased person in MyMinfin. It is not possible to modify or send a previously saved tax return. We are doing our best to solve this problem as quickly as possible.

    This is why we are postponing the deadline for sending returns on behalf of a deceased person online till 31 August 2025. Our staff remain at your disposal if you need help.

    In the event of death, as an heir, legatee or donee, you must, in principle, submit the tax return of the deceased during the normal period over which the tax return should be submitted. For income tax year 2024, this period starts at the end of April 2025. Did the death occur shortly before or during the tax return period? In that case, the final submission deadline is five months after the date of death.

    The time of death may also affect what you fill in on the tax return.

    • To which address will correspondence, such as the tax assessment notice, be sent following death?

      We will send any correspondence to:

      You can also get help through us.

    • What if I want to renounce the estate?

      Then you are no longer required to submit the tax return of the deceased. You can contact your civil-law notary for this, if necessary.
