The Law To Know

Tax Calendar & Filing Requirements

Free

Knowing which forms apply and when they’re due is its own separate skill from actually calculating what’s owed — this tool only does the first part. A short questionnaire about the shape of a tax situation (never an amount) identifies which federal forms and deadlines commonly apply and why — for individual filers, the self-employed, business entities, and rental property or investment sales — with a downloadable calendar file to import into your own calendar app for reminders. Line-by-line walkthroughs explain what each part of 21 federal forms and schedules is actually asking for — from Form 1040 and the core individual schedules through payroll, corporate/partnership, estate & gift, and excise tax forms. Nothing here calculates a number, and nothing you enter is saved anywhere.

This tool explains general US federal filing patterns and deadlines using the IRS’s own public terminology. It does not calculate any tax figure, does not determine what any real filer owes or must file, and does not provide tax or legal advice about any specific situation. For guidance on an actual tax situation, consult a licensed tax professional or the IRS directly.
