What this is

This is a free explainer plus a $29 response-letter pack. It is document preparation, not tax advice, and not a promise that any tax agency will accept the draft. The demo file next to this page holds 20 notices (IRS and two state notices). Every figure on this page is a demo output labeled as a demo.
