Yes. We have noticed that, too. Or at least our admin staff have noticed that stuff is piling up with them. They are not of the same mindset and are very uncomfortable leaving anything for the next day.
We have a policy, that is communicated to all clients with an organizer insert each year, that we do not want to receive documentation “sight unseen.” That is, they send nothing to us until we have a phone interview. At the end of that interview, we have a solid set of notes and a list of what the client needs to supply to us. This way, when we get it, it is not too much, not too little and is not confusing. It is a very controlled process. There are a few exceptions, about how we want certain things prior to year-end, as they arise, like closing statements for real property sales. In addition, if something involves monthly bookkeeping, like a Sch C or Sch E, that is handled during the year as things go. We do no bookkeeping as part of tax return preparation during tax season (except for the prior December work). There are some other exceptions to the general rule, which I can go into if you’d like. But at the end of the day, it is a very controlled process and allows us to keep our schedules straight. If someone, out of the blue, starts emailing tax documentation without our permission first, for example, we put a kibosh on it immediately. If someone mails their tax documentation to us with a phone interview first, they go to the back of the line and are reminded of our policy.
