On the first day of the new filing period a new notification will be sent by mail to you, that starts the compliance process for this period.

From that moment on, the new Mytaxflow is the place where you can co-work together with your Account Manager in order to file the declaration. 

The number of tasks and time needed will differ per filing period. When all the tasks are completed, the declaration is filed, and with that you will be VAT Compliant.
