Exact Online Fiscaal – Error 500 messages and empty tax returns after importing the tax return (NL)

Incident Report for Exact System

Resolved

This issue has been resolved. A permanent solution has been implemented. All tax returns can be opened again. It is possible that not all information is included in the tax return. You will have to re-enter this manually. If the tax return is empty because you have created a tax return for a new year, we recommend deleting the created tax return and creating a new one so all data from the client card is included again. Our apologies for the inconvenience.
