Updated October 19, 2026. Quick answer: Form 2350 is the Application for Extension of Time To File U.S. Income Tax Return for U.S. citizens and resident aliens abroad who expect to qualify for special tax treatment. It asks for more time to meet the bona fide residence test or the physical presence test, and it must be filed on or before the due date of your return. It does not extend the time to pay.
Who should file Form 2350, and who should not
The instructions give a three part test: “You should file Form 2350 if all three of the following apply.” First, “You are a U.S. citizen or resident alien.” Second, “You expect to qualify for the foreign earned income exclusion and/or the foreign housing exclusion or deduction by meeting either the bona fide residence test or the physical presence test but not until after your tax return is due.” Third, “Your tax home is in a foreign country (or countries) throughout your period of bona fide residence or physical presence, whichever applies.”
The purpose statement narrows the group further: “Use Form 2350 to ask for an extension of time to file your tax return only if you expect to file Form 2555” and need the time to meet one of the tests. Everyone else is pointed elsewhere: “All other taxpayers should file Form 4868”. The form also limits repeat use: “Do not file Form 2350 more than once for each move overseas.”
The two tests the form depends on
The bona fide residence test is described this way: “To meet this test, you must be a U.S. citizen who is a bona fide resident of a foreign country (or countries) for an uninterrupted period that includes an entire tax year.”
The physical presence test is a day count: “To meet this test, you must be a U.S. citizen or resident alien who is physically present in a foreign country (or countries) for at least 330 full days during any 12month period.”
Both tests need a tax home abroad. The instructions define it: “Generally, your tax home is your regular or main place of business or post of duty regardless of where you maintain your family home.” They also say “A foreign country is a country other than the United States or any of its territories.”
Walking the lines of the form
The top of the form takes names, addresses and social security numbers. The instructions add “Don’t abbreviate the country name.” Then the numbered lines begin. The table lists each one as the form prints it.
| Line | As printed on the form |
|---|---|
| Line 1 | “because my tax home is in a foreign country and I expect to qualify for special tax treatment by meeting the” |
| Line 2 | “Were you previously granted an extension of time to file for this tax year?” |
| Line 3 | “Will you need additional time to allocate moving expenses?” |
| Line 4a | “Date you first arrived in the foreign country” |
| Line 4b | “Date qualifying period begins” |
| Line 4c | “Your foreign home address” |
| Line 4d | “Date you expect to return to the United States” |
| Line 5 | “Enter the amount of income tax paid with this form” |
For line 1, the instructions explain the date to enter. “If you plan to qualify for the bona fide residence test, enter the date that is 12 months and 30 days” from the start of the next full tax year, and for the physical presence test the count starts “from your first full (24hour) day in the foreign country.”
Lines 4a to 4d fill in the arrival and qualifying dates. “Enter the day, month, and year of your arrival in the foreign country.” For line 4d, “If you have no planned date, leave this line blank.” Line 5 is for any payment: “Note: This is not an extension of time to pay tax.”
When to file, where to send it and how long you get
The form states “File Form 2350 on or before the due date of your Form 1040 or 1040-SR.” The advice on timing is “You should file Form 2350 early enough so that if it isn’t approved, you can still file your return on time.”
Electronic filing is recommended, and the form says so: “The IRS recommends electronic filing whenever possible.” One group has no choice: “If you are a fiscal year taxpayer, you must file a paper Form 2350.” For paper filing the form prints a mailing address in Austin, so check the address on the current revision before you send anything.
The length of the extension is stated in the instructions. The table shows the figures as printed, together with the penalty figures in the same instructions.
| Item | As printed on the form |
|---|---|
| Physical presence test | “physically present in a foreign country (or countries) for at least 330 full days during any 12month period” |
| Date on line 1 | “enter the date that is 12 months and 30 days (90 days if allocating moving expenses)” |
| Usual period of extension | “it will generally be to a date 30 days after the date on which you expect to meet either the bona fide residence test or the physical presence test” |
| With moving expenses | “you may be given an extension up to 90 days after the end of the year following the year you moved to the foreign country” |
| Grace period on the IRS notice | “we have granted a 45day grace period” |
| Late filing penalty | “It is usually 5% of the tax not paid by the regular due date for each month or part of a month your return is late.” |
| Penalty maximum | “Generally, the maximum penalty is 25%.” |
| Minimum late filing penalty | “If your return is more than 60 days late, the minimum penalty is $525 or the balance of tax due on your return, whichever is smaller.” |
Paying, penalties and what happens after
The caution box says “Form 2350 doesn’t extend the time to pay taxes.” On interest, “You will owe interest on any tax not paid by the regular due date of your return”. The form also warns that an approval can be undone: “If we give you more time to file and later find that the statements on this form are false or misleading, the extension is null and void.”
After you file, the IRS completes the Notice to Applicant. The instructions say “You must complete the Return Label to receive the Notice to Applicant.” and “Don’t attach the notice to your return”. When you later file the return, “You may file Form 1040 or 1040-SR at any time before the extension expires.”

Which revision applies
The edition read for this page is Form 2350 (2025), which carries its own instructions and is the revision irs.gov served when it was read on 2026-10-19. Check the revision printed on the form you are filing, because a later revision can change the dates, the mailing address and the filing options.
Common mistakes
- Using Form 2350 when it does not fit. The instructions say “All other taxpayers should file Form 4868”
- Treating the extension as time to pay. The form says “Form 2350 doesn’t extend the time to pay taxes.”
- Missing the filing date. The instructions say “We cannot consider your application because it was filed after the due date of your return.”
