Fill out Form 1040 for 2025 tax season

What is Form 1040?

Form 1040, U.S. Individual Income Tax Return, is the form most people use to file their federal income taxes. It brings together your income, adjustments, deductions, credits and payments, and shows whether you get a refund or owe tax.

Who needs to file Form 1040?

Whether you must file depends on your filing status, age and gross income; the IRS publishes the thresholds for each year. You also have to file if you had $400 or more in self-employment earnings. Even if you don't have to, filing gets back tax that was withheld and refundable credits.

How to fill out Form 1040?

1. Gather your W-2s, 1099s and records of deductions, then open the 1040 in the Profi PDF editor.

2. At the top of page 1, enter your name, SSN, address and filing status, and list your dependents.

3. Lines 1–9: report wages from W-2 box 1, interest, dividends, IRA and pension distributions, Social Security benefits, capital gains, and other income from Schedule 1.

4. Enter adjustments from Schedule 1, Part II, to reach your adjusted gross income on line 11.

5. Subtract the standard deduction, or itemized deductions from Schedule A, to get your taxable income.

6. Work out your tax, then subtract credits such as the child tax credit, using Schedules 2 and 3 where needed.

7. Enter payments: tax withheld on W-2s and 1099s, estimated payments and refundable credits.

8. Enter your refund (with direct deposit details) or the amount you owe.

9. Download and print the return, sign page 2 (both spouses if filing jointly), attach your W-2s and mail it.

When is Form 1040 due?

Usually April 15, or the next business day when it falls on a weekend or holiday. With Form 4868 you get until October 15 to file, but tax you owe is still due in April.

Where do I file Form 1040?

Mail it to the IRS address for your state. The address also depends on whether you enclose a payment, and the Form 1040 instructions list them all. Profi PDF helps you fill out the form; it doesn't file it for you.

Do I need to sign Form 1040?

Yes. An unsigned return is not valid, and on a joint return both spouses sign. For a return you mail, print it and sign in ink.

When is Form 1040 not required?

If your income is below the filing threshold for your status and age, and no special rule applies (such as self-employment income), you don't have to file. You may still want to, to claim a refund of withheld tax or refundable credits.
