I paid a tax on the due date, but a message appears in MyTax saying that the tax is still not paid. Why?
Amounts arriving from taxpayers may be booked in MyTax with a delay if there has been a public holiday in the middle of the week (e.g. Christmas). In this case, a message may appear in MyTax about an unpaid tax even though you have paid it. You can disregard the message.
However, we recommend that you make a check in MyTax in order to ascertain that the message does not refer to any other overdue taxes you may have.
