Tax office officials assume that those who have had their records lost have their returns on their computer and will be able to easily resend them. They have until 1 April to do so.
According to Radio Netherlands, earlier in February, "another problem with the tax office computers meant that clients were unable to identify themselves properly. For a whole week, nobody was able to submit a tax declaration electronically."
Last June, tax office software that did not function correctly forced over 400,000 companies to resubmit payroll information.
