Steps
Select Calendar in the sidebar.
Under Tasks, choose My tasks for the deadlines of tasks assigned to you, or All tasks for every task deadline you have access to.
Under Calendars, select a tax type, such as VAT, to add its filing and payment deadlines. Each tax type has its own color.
Use Entities to show the deadlines of one or more entities only.
Switch between Day, Week, Month and Agenda at the top right. Agenda lists the deadlines day by day. Use the arrows to move to another month.
Select a deadline to open it.
Reading a deadline
Each task shows the entity, the assignee and the due date, with the country, workflow and period below. The label on the right tells you where it stands:
Overdue: the due date has passed. Overdue work is marked in red, so follow up on that first.
Blocked: an earlier task must be finished first.
Completed on time: the work is done.
