What Is Form 1040: U.S. Individual Tax Return?

If you earn income in the United States, Form 1040 is the document you use to report it to the IRS. This is the standard individual tax return form, and it’s how you show your taxable income, claim deductions, and ultimately determine whether you owe taxes or are due a refund.

Form 1040 is organized into sections that walk you through your income, deductions, and credits. Think of it as the blueprint of your financial year, condensed into a structured, official form.

Who Needs to File

Most taxpayers must file Form 1040 by April 15 each year. If you earn above a certain income threshold, the IRS expects you to file. Businesses have different forms, so we’re only talking about individual taxpayers here.

Filing requirements generally fall under three categories:

1. Income Thresholds – The IRS sets a minimum income level based on your filing status and age. For example, in 2024, a single person under 65 must file if their gross income exceeds $14,600. Couples filing jointly have a threshold of $29,200, and heads of household $21,900. These amounts are adjusted slightly each year for inflation.
2. Dependents – Children or others claimed as dependents may not need to file unless their income exceeds certain limits. For 2024, a dependent must file if they earn over $14,600, or have unearned income above $1,300 but below $13,000.
3. Special Situations – Some circumstances trigger filing regardless of income, like owing alternative minimum tax, taking distributions from a health savings account, earning $400 or more in self-employment income, or receiving wages from a church.

How to File Form 1040

You can download Form 1040 directly from the IRS website. It’s two pages long, and you can either mail it in or e-file it. The form begins by asking for your personal information: name, address, Social Security number, and details about your dependents. You’ll also indicate your filing status and have the option to contribute $3 to presidential campaign funds.

Next, you report your income. This includes wages, salaries, interest, capital gains, pensions, Social Security benefits, and other income sources. Recent tax law changes eliminated many deductions, like unreimbursed employee expenses, moving costs for work, and tax preparation fees.

Form 1040 follows a “building block” approach. You only add the supplemental schedules you need, depending on whether you have extra income, owe additional taxes, or qualify for certain credits. Many taxpayers, however, file just the 1040 without any schedules.

Types of Form 1040

Not everyone uses the standard Form 1040. Variants exist for specific situations:

Form 1040-NR – For nonresident aliens engaged in U.S. trade or business, or representatives of estates or trusts that must file.
Form 1040-SS & 1040-PR – For residents of U.S. territories with self-employment income; 1040-PR is the Spanish-language version.
Form 1040-ES – For estimating and paying quarterly taxes on income not subject to withholding.
Form 1040-V – A payment voucher for submitting owed taxes.
Form 1040-X – To correct mistakes on previously filed returns.
Form 1040-SR – Designed for taxpayers over 65, featuring larger font and a simplified standard deduction chart.

Standard Deductions

Your filing status determines your standard deduction. For 2024, single filers and those married filing separately can claim $14,600. Couples filing jointly get $29,200, and heads of household $21,900. These amounts rise slightly each year. If you’re over 65 or blind, you may qualify for additional deductions.

Some taxpayers, like estates, trusts, or nonresident aliens, cannot take the standard deduction.

Supplemental Schedules

Form 1040 uses schedules to handle more complex financial situations:

Schedule 1 – Reports additional income or adjustments like alimony, educator expenses, or unemployment benefits.
Schedule 2 – Covers additional taxes, including self-employment tax, alternative minimum tax, and IRA taxes.
Schedule 3 – Records extra credits or payments, such as child care or energy credits.
Schedule A – Itemized deductions, including medical, taxes, interest, and theft losses.
Schedule B – Interest and dividends over $1,500.
Schedule C – Net profit from business or sole proprietorship.
Schedule D – Capital gains and losses.
Schedule E – Supplemental income from rentals, royalties, partnerships, and trusts.
Schedule EIC – Verifies qualifying children for the Earned Income Credit.

Other schedules exist for specialized purposes, like farming, household employment taxes, self-employment taxes, and credits for children or the elderly.

Is Form 1040 the same as a W-2?

No. A W-2 reports your income from an employer. You use that information to complete your 1040.

Where do I get Form 1040?

It’s available on the IRS website for download or digital completion. Some public buildings may have paper copies, but it’s not mailed to you like a W-2.

What’s the difference between a 1040 and a 1099?

A 1099 reports income from independent work or other sources. You use that information to fill out your 1040.

The Bottom Line

Form 1040 is the backbone of tax filing for U.S. taxpayers. All financial statements and schedules eventually feed into it. No matter your filing status, income, or personal situation, if you file taxes, you’re filing some version of Form 1040. It’s your official record of income, deductions, and credits—a document that tells the IRS exactly where you stand financially.
