What is a 1040 Form?
IRS Form 1040 is the standard form U.S. taxpayers use to file an annual income tax return. It reports income from wages, self-employment, dividends, and other sources, while letting you claim deductions such as mortgage interest and credits like the Earned Income Tax Credit or Child Tax Credit. The form calculates your total taxable income and determines whether you owe the federal government or qualify for a refund, making it the central document linking your yearly finances to your tax outcome.

Form 1040 is due April 15 each year for calendar-year filers, covering the 2025 tax year with a 2026 deadline. Fiscal-year filers owe theirs by the 15th day of the fourth month after their year ends. A weekend or holiday pushes the date to the next business day. Form 4868 extends filing to October 15, but not payment.

When is a 1040 not required?
Filing drops away once your income falls under the threshold for your status and age, such as $15,750 single or $31,500 married filing jointly, with no self-employment, AMT, or advance credit reconciliation due. Nonresident aliens file a 1040-NR instead, and dependents can often be claimed on a parent's return.
