Pre-completed tax return

In March or April 2021, you will receive a pre-completed tax return. If there is no need for corrections or additions in your return, you do not have to do anything.

If you want to make corrections, the deadline for them is 4 May, 11 May or 18 May 2021. You can check the deadline date on your tax return and in MyTax.
