What is Form 4868? (How to Get a Tax Extension)

Some people need a bit of extra time to file their income tax return (Form 1040). If you think you’ll need more time this year, you’ll have to file for an automatic deadline extension using Form 4868.

Here we’ll go over how to complete a Form 4868 extension request, how to file it, and when it’s due.

What is Form 4868?

Form 4868, ‘Application for Automatic Extension of Time to File U.S. Individual Income Tax Return,’ is the IRS form that U.S. taxpayers use to request an automatic six month tax extension for their federal tax return (Form 1040).

Although filing 4868 automatically extends the deadline for filing your return, it doesn’t extend the amount of time you have to pay your federal income tax. If you want to file 4868 properly, you’ll have to do the following:

  1. Estimate your 2020 tax liability using the information you currently have
  2. Enter your total tax estimated liability on line 4 of Form 4868
  3. Pay that tax liability by the regular due date

If you pay late, you’ll have to pay interest, and might also incur a late payment penalty. (Even if you file Form 4868.)

Who needs to file Form 4868?

Form 4868 applies to anyone who needs more time to file Form 1040, Form 1040-SR and Form 1040-NR.

If you need more time to file other tax forms, use Form 7004 to request a six month extension.

How to file it

Form 4868 is a simple, one page form from the IRS that looks like this:


It’s divided into two parts:

Part I will ask you for your personal information, including your name, address, social security number and spouse’s social security number.

Part II is where you’ll estimate your total tax liability and payment for 2020.

Use Line 4 to record the total tax liability you expect to report on the following tax forms:

Record any tax payments you’ve made for the 2020 tax year so far on Line 5. Subtract Line 5 from Line 4 to get your total tax due (Line 6). Record the total amount you intend to pay on Line 7.

(Remember: if you fail to pay your taxes by the regular deadline, you will pay interest charges, and might also incur a late filing penalty.)

Check the box on Line 8 if you’re a U.S. citizen and are out of the United States at the time of filing, and the box on Line 9 if you didn’t receive wages as an employee subject to U.S. income tax withholding.

When is 4868 due?

The filing deadline for Form 4868 is April 15, 2021, the date you would have filed your income tax return.

Where to file form 4868
