Description
Organize amended-return and prior-year work from intake through follow-up. This guide helps you identify what changed, gather the right records and work through Form 1040-X or unfiled returns.
What’s Included
- 9 chapters across amended returns, prior-year and unfiled returns, and running the work as a service.
- Form 1040-X column explanations, amendment examples, refund-window references and common errors.
- Transcript and intake guidance, prior-year triage, substitute-for-return discussion and resolution hand-off considerations.
- Sample engagement clauses, pricing considerations and document checklists.
How You’ll Use It
Identify the years involved and the records you need, then follow the relevant amendment or catch-up workflow. Use the examples to distinguish preparation work from matters that need a separate tax-resolution engagement.
Who It’s For
Preparers handling corrected returns or adding prior-year preparation to their services.
