What Is Form 1040?
Form 1040 is the main U.S. individual income tax return, where you report your income, claim deductions and credits, and figure out your refund or balance due.
Almost everyone who files a federal income tax return uses Form 1040. It pulls together income from all sources, such as wages, self-employment, and investments, and applies your deductions and credits to arrive at your taxable income and final tax.
Many people attach additional schedules to the 1040 depending on their situation. For example, Schedule C reports business profit, Schedule SE figures self-employment tax, and other schedules handle things like itemized deductions or extra income. The 1040 then ties all of these together into one return.
The form compares the total tax you owe against what you already paid through withholding and estimated payments. If you paid more than your tax, you get a refund; if you paid less, you owe the difference.

FAQ
Frequently asked questions
What are the schedules attached to a 1040?
Schedules are add-on forms for specific items, such as Schedule C for business income or Schedule SE for self-employment tax, that feed into the 1040.
How does the 1040 decide my refund?
It totals your tax, then subtracts payments you already made through withholding and estimated taxes. Overpayment becomes a refund; underpayment is owed.
