What the kickoff should cover

Clients need three things from the first email of the season: what to send, how to send it and by when. Anything else belongs in a later message.

  • A checklist personalised from last year’s return
  • One secure way to send documents
  • Your internal target date, earlier than the IRS deadline
  • Who to contact with questions

Remind clients to wait for complete forms

IRS Tax Tip 2025-10 says taxpayers need all their year-end income documents to file a complete and accurate return, and lists the common ones: W-2, 1099-MISC, 1099-INT, 1099-NEC, 1099-G and 1095-A. Ask clients to send the full set rather than a first batch.

Fewer documents to ask for

For clients whose books you keep in HelloBooks, the kickoff list can be much shorter. Bank activity, categorised expenses and contractor totals are already in the ledger, so the email asks only for what the books cannot show, such as W-2s and brokerage forms.

FAQ

Frequently asked questions

When should the kickoff go out?
Early January, before W-2s and 1099s arrive, so clients know what to watch for.
Does the kickoff need an unsubscribe link?
If it is purely about the client’s existing engagement it may be transactional, which the FTC treats narrowly. If it also promotes services, include the opt-out and your physical address.
