The first report you have to do in person, the day of arrival is day one and from there you count 90 days. You can do this in person between 15 days before this 90th day or 7 days after. Your second and consecutive reports you can do on-line, as your details are now in the system, you do the on-line reporting between 15 and 7 days before the due date. If you make a report you get a small slip of paper with a new due date. The link for on-line reporting
