Form Overview

IRS Form 1040 - U.S. Individual Income Tax Return

Form 1040 is the U.S. individual income tax return used to report annual earnings, deductions, credits, and tax liability. Taxpayers file it each year to settle their federal tax obligations.

It captures wages, interest, dividends, self‑employment income, deductions, tax credits, and the resulting tax due or refund.

  • Filing date: The return covers the prior calendar year and is normally due April 15 of the filing year, unless an extension is filed.
  • Preparation window: collect IDs, supporting records, and signatures in advance.
