verification fiscal

On systems (POS) of our customers we do every year a verification fiscal. You can have a report that gives us the deadlines for each month?

I'm not sure I'm following your questions. In case you manage these dates using Task you can either generate one of the Reports under Calendar subject or use Tasks tab in the Calendar filtered by the required date range. In case this does not answer your question please elaborate more about what you ask/try-to-achieve.
