What is Form 1040?
Form 1040 is the standard U.S. individual income tax return filed with the IRS each year. It is used by employees, self-employed individuals, freelancers, retirees, and anyone else who earns income in the United States to report what they earned, calculate how much tax they owe, and claim any deductions or credits they qualify for. Filing accurately ensures you pay the right amount — and get back any overpayment through a refund.
What is Form 1040 used for?
Form 1040 covers three core purposes when it comes to federal income taxes:
- Reporting your total income for the calendar year to the IRS.
- Calculating the amount of tax you owe, or determining the refund you are entitled to receive.
- Claiming deductions, credits, and adjustments that reduce your taxable income or overall tax liability.
Who is required to file Form 1040?
Whether you are required to file a 1040 depends on your gross income, filing status, age, and the nature of your income. The IRS updates filing thresholds each year, so the specific income level that triggers a filing requirement changes annually. If your income exceeds the threshold for your situation, you are required to file regardless of whether you expect to owe tax or receive a refund.
Frequently asked questions
When is Form 1040 not required?
You may not be required to file if your total income falls below the IRS threshold for your filing status and age. These thresholds are adjusted each year, so check the current IRS guidelines to confirm whether filing is required for the tax year in question. Some individuals below the threshold may still choose to file in order to receive a refund of withheld taxes or to claim refundable credits.
When is Form 1040 due?
The annual deadline for Form 1040 is April 15. If that date falls on a weekend or a federal holiday, the deadline shifts to the next business day. Taxpayers who need more time can request an automatic six-month extension, though any tax owed is still due by the original April deadline.
Check the IRS website each year for any deadline changes, as extensions have been granted in prior years due to exceptional circumstances.

How is Form 1040 filed?
Most taxpayers file electronically using the IRS Free File program, IRS-authorised tax software, or a tax preparer who submits e-file returns. Electronic filing is faster, more secure, and results in quicker refunds.
If you prefer to file by paper, mail your completed return to the IRS address listed in the official 1040 instructions for your state and whether or not you are including a payment.
