What Is IRS Form 1040?
Form 1040, officially titled the U.S. Individual Income Tax Return, is the standard form used by individuals to file their federal income taxes. It's issued and updated annually by the Internal Revenue Service (IRS).
With Form 1040, you report your income, claim tax deductions and credits, and determine whether you’ll receive a refund or owe additional taxes for the year. The form also includes your filing status, dependents, and total tax payments.
Each tax year may bring small changes to the form, such as updated tax brackets or new credit lines, so it's important to use the correct version for the year you're filing.
