What Is a Tax Return?

A tax return is the form you file to report your income, deductions, credits, and calculate your tax liability. For most individuals, this is Form 1040. On a tax return, you tell the IRS your complete financial picture for the year — all income sources, applicable deductions, and credits — and calculate either the tax you owe or the refund you are entitled to.

Think of a tax return as your side of the story. You are presenting your financial narrative to the IRS and showing how much tax you should pay or receive back.

What Is an Information Return?

An information return is a form filed by someone else who paid you. It reports factual information to the IRS without calculating any tax. Common information returns include W-2 (filed by employers reporting wages), 1099-INT (filed by banks reporting interest), 1099-NEC (filed by clients reporting payments to contractors), and 1099-B (filed by brokerages reporting stock transactions).

Information returns serve as the IRS's verification system. They allow the IRS to cross-check your tax return against what third parties report about your income. This is why accuracy on your tax return is critical — the IRS already has information about most of your income.

Why This Distinction Matters

Understanding the difference helps you realize that the IRS has substantial information about your income before you even file. Banks, employers, brokerages, and clients all report what they paid you through information returns. If your tax return does not match this information, you will likely receive a CP2000 notice or other correspondence from the IRS.

As a taxpayer, you should collect and review all information returns (W-2s, 1099s) you receive before filing your tax return to ensure everything is accurately reported.

Frequently Asked Questions

Do I need to attach information returns to my tax return?

If you file electronically, information returns are not attached. If you file by mail, you should attach any W-2 forms. 1099 forms are generally not attached to paper returns, but the income must be reported.

What if I receive an incorrect W-2 or 1099?

Contact the issuer and request a corrected form. If they issue a correction, they will send you and the IRS a corrected copy. If you cannot get a corrected form, file your return with the correct amounts and include an explanation.
