Form 1040, officially known as the U.S. Individual Income Tax Return, is the standard IRS tax form used by U.S. taxpayers to file their annual federal income tax returns. It is used to report your total income, claim allowable deductions and credits, and calculate whether you owe additional tax or are due a refund
. The form collects personal information such as your name, Social Security number, filing status, and information about dependents. It also reports various types of income, calculates your adjusted gross income (AGI), and applies tax credits and payments already made during the year. The final result determines your tax liability or refund amount
. Form 1040 consists of two pages and may require additional schedules depending on your tax situation. There are also variations of Form 1040 for specific taxpayers, such as Form 1040-SR for seniors, Form 1040-NR for nonresident aliens, and Form 1040-X for amendments
. Taxpayers must file Form 1040 by Tax Day, typically April 15 of the following year, with an option to request an extension to October 15 for filing (but not for payment)
. In summary, Form 1040 is the primary document used by individuals to report income and calculate federal income taxes owed or refunded to the IRS each year
