Form pages explain what each IRS form is commonly used for and what records a taxpayer should collect before filling it out.
Start with the page closest to the letter or problem in front of you. Then compare it with a form page, a checklist, and an official source before deciding what to send.
For large balances, payroll tax, levy action, Tax Court deadlines, or possible criminal questions, use these pages to prepare for professional advice rather than to handle the matter alone.
