Form 1040 (US Individual Income Tax Return)
Definition
The standard federal income tax return form filed by US individual taxpayers. All taxpayers use Form 1040, with additional schedules as needed (Schedule A for itemized deductions, Schedule C for business income, Schedule D for capital gains, etc.). The simplified forms 1040-EZ and 1040-A were eliminated after 2017, replaced by the redesigned 1040 with supplemental schedules.
Example
When you file your taxes, Form 1040 is the main form. It starts with your total income, subtracts adjustments and deductions, calculates your tax, subtracts credits and payments, and determines if you owe money or get a refund.
