With the October 15th deadline right around the corner, you may find yourself needing a bit more time to collect or organize all your foreign financial records to complete your tax return. This is when it’s a good idea to be aware of Form 4868, the “Application for Automatic Extension of Time to File US Individual Income Tax Returns.” In this article, you will learn about the finer details of Form 4868, when it’s applicable, and how to file it.

What Is Form 4868?

Depending on your residency, US tax deadlines can change. To help better understand the differences, here is a table detailing tax extensions for filing and paying taxes.

Who Must File Form 4868?

For people who have complex tax cases, filing an extension for the October 15th deadline can be quite beneficial. Form 4868 is frequently used by self-employed individuals, investors, business owners, and taxpayers undergoing significant life changes, such as US expats.

Even if you think you may not need an extension for the October 15th deadline, filing form 4868 ensures you have additional time free of certain penalties. Whether you require an extension or not, filing can ensure you have flexibility and peace of mind.

Form 4868 vs. Filing an Amended Return

Filing an extension and amending a return are very different processes. Form 4868 provides you with additional time to file your tax return, but if you have already submitted it with incorrect information, you cannot use Form 4868 to correct it. To fix a mistake, you need to file Form 1040-X to amend your return. Form 4868 cannot fix previously submitted returns; only Form 1040-X can amend your past return.

Puerto Rican & Overseas Filers

US citizens or Green Card Holders living outside of the US receive an automatic two-month extension until June 15th with the possibility of filing for an October extension. This possibility also extends to Puerto Rico residents. Otherwise, if you are not outside of the US or in Puerto Rico, please file your extension before April 15th.

How to Request a Form 4868 Extension

There are three ways you can file an extension:

  1. Electronically: Submitting Form 4868 using tax preparer software like what MyExpatTaxes offers or via the IRS website.
  2. By Mail: Paper mailing is still an option for those of you who prefer to file Form 4868 this way. Make sure it is postmarked by the filing deadline though.
  3. With a Tax Professional: You can get a Tax Professional to file Form 4868 on your behalf.

You can file Form 4868, as you choose as long as your file before the deadline, which is April 15th for residents of the US, and June 15th for expats outside of the US.

Preparing Form 4868

Personal Information (Lines 1-3): Provide your name, address and Social Security number. If you are married filing jointly, include your spouse’s information as well.

Estimated Tax Liability (Line 4): You must estimate the taxes you are expected to owe for the year. If you expect to get a refund, enter 0.

IRS Payments (Line 5): Include any payments you’ve already made to the IRS this year.

Balance Due (Line 6): Subtract the amount on Line 5 from your estimated tax liability on Line 4 to calculate the remaining balance due. If you get a refund, you’ll need to enter that amount in Line 7 instead.

Amount Paid with Extension (Line 7):  Enter the amount you are paying with your extension request. If you owe nothing, enter 0.

Out of the Country (Line 8): Check this box if you are a US citizen or resident living abroad to indicate that you’re eligible for the automatic two-month extension.

Submitting Form 4868 to the IRS

Once you have filled out your form, you can head to the IRS website and submit it using one of their trust partners. Now, you should receive an automatic extension. You can choose to continue downloading your IRS forms, fill them out individually, and file them, or you can sign up and file using US tax software.

Filling out the form will address your income and tax liability, and payment estimates should include your and your spouse’s combined income.

Form 4868 and State Tax Returns

Form 4868 is specifically for extending your federal tax return deadline, but it can also automatically extend your state return deadline, depending on your state. Some states, such as California and Illinois, offer an automatic extension if you file Form 4868.

If you would like to learn more about filing an extension for your state return, check out this article: State Taxes and Extensions. It can provide you with information about whether your state grants automatic extensions based on federal extension Form 4868.

What Happens If You Miss the Form 4868 Deadline?

The golden question is, what happens if I miss the deadline to file Form 4868? Well, your return will be considered late; therefore, subject to penalties. You could be looking at the following:

The Failure to File penalty is 5% of the unpaid taxes for each month or part of a month that a tax return is late. The penalty won’t exceed 25% of your unpaid taxes.

The Failure to Pay penalty is 0.5% of the unpaid taxes for each month or part of a month the tax remains unpaid. The penalty won’t exceed 25% of your unpaid taxes.

Practice filing Form 4868 even if you don’t think you’ll need it because it could save you from potential penalties.
