A reminder a month before your dates
Clients get an email a month before each date that is theirs, with the list of papers we still need. A second note follows a week before if anything is missing.
- Only the dates that apply to you
- The papers we still need, in one list
- No reminders in the quiet months

Talk it through first
A first meeting takes 30 minutes, at the office or by video, and costs nothing. Bring your last return and any letters.
