Taxpayer field guides · Four starting points

Start with a real-life question.

Follow a documented sequence from the first question to the next useful source. Each guide includes a fictional case, a review checklist, and connections to the interactive tools.

Use a sequence, not a shortcut.

Identify the document and taxpayer, establish the relevant period, separate facts from assumptions, and follow each amount to its rule. These guides teach that process; they do not decide a filing position for an individual.
