The malfunction at the tax authorities has been resolved, a spokesperson reported to on Friday.

However, the tax authorities are not yet increasing the capacity of the number of people who can file a tax return at the same time to one hundred percent.

People who want to file a declaration on Saturday or Sunday may therefore still run into the limitation.

The capacity is limited to ensure that people who do manage to log in to My Tax and Customs Administration can successfully file their tax return, the tax authorities wrote on its website on Friday.

"We also know that many people want to file a declaration at the same time at the weekend. We use as much capacity as possible, but it may happen that you cannot log in immediately," warns the organization.

The Tax and Customs Administration has been struggling with problems since 1 March.

Because of the problems, people are given a week longer to report the crime.

The data must be submitted to the tax authorities no later than 8 May.

The spokesperson was unable to go into more detail at the time of publishing this article, but was able to provide more details later Friday afternoon.
