I'd love to send mine out today, but I can't get Engagement Letters yet unless I roll all my clients over one by one. The batch rollover in Drake will be available this week... they're late, probably due to the huge tax law changes. In prior years we've had everything printed out, envelopes stuffed, ready to pop in the mailbox on the first business day of the year. Not this year, though - so we have our checklist and general letter printed and ready, and mailing labels ready. As soon as we get batch rollover out they go!
Then we'll start on payroll client W2s and business client 1099s. It begins! God help us all.
