Form 2350 is not a regular extension. It exists for one job, giving expats more time to file until they actually meet a Foreign Earned Income Exclusion test.
Key Takeaways
- Form 2350 is the IRS extension for expats who need time to meet the bona fide residence test or the 330 day physical presence test before filing with Form 2555. It is purpose built for FEIE timing, not a general extension.
- File by your original due date. If you live and work abroad on that date, you usually have an automatic 2 month filing window, for 2024 returns that was June 16, 2025 because June 15 fell on a Sunday. Interest still runs from April.
- The 2350 extension usually ends 30 days after you expect to qualify under the chosen test. In limited moving expense allocation cases, the IRS may grant up to 90 days beyond the end of the year after your move.
- This extends time to file, not time to pay. Estimate and pay by the original deadline to reduce interest and avoid penalties.
- Filing method. In 2025, authorized software can transmit Form 2350 through IRS Modernized e File, otherwise mail it to the IRS in Austin, TX. Always follow the current year instructions for the correct address.
What is IRS Form 2350 and who actually needs it
If you are a U.S. citizen or resident alien abroad, have a foreign tax home, and you expect to claim the Foreign Earned Income Exclusion on Form 2555, but you will not meet the bona fide residence test or the 330 day physical presence test by your regular filing deadline, use IRS Form 2350 to request a later filing date.
Two common paths qualify you for FEIE:
- Bona fide residence, an uninterrupted period that includes an entire tax year, or
- Physical presence, at least 330 full days in one or more foreign countries during any 12 consecutive months.
For 2025 returns, the FEIE cap is 130,000 per qualifying person. For 2024 returns, it is 126,500. If both spouses qualify and each has foreign earned income, each may claim up to the cap. Your exclusion still gets prorated if you qualify for only part of the year.
How Form 2350 differs from a regular extension on Form 4868
A regular extension, Form 4868, gives most taxpayers until October 15 to file. It does not care about FEIE timing. Form 2350 exists only to let expats file after they meet FEIE eligibility, usually 30 days past the date you expect to qualify. Both are filing extensions only, not payment extensions.
| Item | Form 4868 | Form 2350 |
| Purpose | General automatic extension | FEIE focused extension to meet bona fide residence or 330 day physical presence |
| Resulting deadline | Fixed to Oct 15 for most calendar year filers | Usually 30 days after your expected qualifying date, up to 90 days in limited moving expense allocation cases |
| Who uses it | Anyone needing more time | Expats who will qualify for FEIE after the original due date |
| Filing method | Widely e filed or by mail | Can be filed through authorized software in 2025 or mailed to IRS Austin, confirm address each year |
| Payment rules | Pay by April due date | Pay by April due date, interest still runs if unpaid |

The automatic 2 month rule for Americans abroad
If you live and work outside the U.S. on your regular due date, you get an automatic 2 month extension to file and pay. For calendar year 2024 returns, that pushed filing to Monday, June 16, 2025 because June 15 was a Sunday. You still owe interest from April on any unpaid balance. To use this, attach a short statement to your return explaining that you qualified under the out of country rule.
When the automatic 2 months is not enough
If your 330 day period or bona fide residence year ends after that automatic window, file Form 2350 by your regular due date, including the automatic 2 month rule if it applies to you. That way, your final filing due date aligns with your expected qualification date, typically plus 30 days.
Eligibility and timing, made simple
Use Form 2350 only if all three are true:
- You are a U.S. citizen or resident alien,
- Your tax home is in a foreign country, and
- You reasonably expect to meet the bona fide residence or physical presence test after your original due date.
When to file. File Form 2350 by your original due date. If you qualify for the automatic 2 months because you are out of the country, that June date becomes your Form 2350 filing deadline for a calendar year return. Filing later will not secure the extension.
How long it lasts. The IRS usually grants 30 days beyond your expected qualifying date. In certain moving expense allocation situations, the IRS may grant up to 90 days after the end of the year following your move.
How to complete Form 2350, step by step
Follow this simple flow.
1.Confirm your test and dates
- Decide whether you will rely on the bona fide residence test or the 330 day physical presence test.
- Mark the exact date you expect to qualify, for example, your 330th full day abroad within your chosen 12 month period. A full day means 24 hours beginning at midnight.
- Fill out identification and tax period
- Enter your name, address, and SSN or ITIN.
- Specify the tax year for the return that will include Form 2555.
- Pick your requested extension end date
- Request an extension that ends 30 days after your expected qualifying date. If a weekend or holiday interferes, the IRS will adjust to the next business day.
- Estimate and pay any tax by the original due date
- This is a filing extension, not an extension to pay. Use IRS Direct Pay or EFTPS to reduce interest and late payment penalties. Keep confirmations.
- Sign and send
- Sign the form. If a preparer is signing for you and the request seeks more than an October 15 date, an original signature is required under IRS processing rules.
Where and how to file in 2025
Mailing. The IRS instructs taxpayers seeking the special FEIE extension to file Form 2350 with the IRS in Austin, Texas. Current instructions reference Austin ZIP codes that may differ across IRS pages, which is normal when addresses are updated. As of November 22, 2025, the Instructions for Form 2555 direct Form 2350 to Austin, TX 73301 0045, while Publication 54 lists Austin, TX 73301 0215 for out of country correspondence, including Form 2350. Use the address in the current year IRS instructions you rely on when you prepare the form, and keep proof of mailing.
Electronic filing. In 2025, the IRS Modernized e File platform includes a schema for Form 2350, so authorized software can transmit it electronically. If your software or preparer does not support it, mail the paper form to the Austin address in the current instructions.
Private Delivery Services. If you use a designated private delivery service, make sure you use the correct street address and retain the tracking that shows the date. The IRS Where to File pages publish the current addresses and service guidance each year.
What to gather before you file
- Passport stamps and travel logs that show foreign presence days.
- Your expected qualifying date under the chosen test.
- Prior Form 2555 details if you claimed FEIE in earlier years.
- Estimates of foreign earned income and housing amounts for the return year.
- Payment method and confirmation for any tax you pay with the request.
Two clear examples you can copy
Example A, 330 day physical presence
You left the U.S. on December 1, 2024 and arrived in Portugal on December 2, 2024. Your first full day abroad is December 3, 2024. You plan to use a 12 month period December 3, 2024 to December 2, 2025. Your 330th full day lands on October 28, 2025. For your 2024 return due April 15, 2025, you file Form 2350 by the due date, including the automatic 2 month rule if you qualify, and request an extension that ends 30 days after October 28, 2025. You still pay any 2024 tax by April 15, 2025.
Example B, bona fide residence
You moved to Tokyo on August 10, 2024 and remain there through December 31, 2025. You will first meet bona fide residence for a full tax year in 2025. For the 2024 return, file Form 2350 by your due date and request an extension that ends 30 days after January 1, 2026, the point at which you can show a full year of bona fide residence. If your software cannot transmit Form 2350, mail it to the current Austin address and keep the courier receipt.
Extension length, limits, and the payment rules that trip people up
How long it lasts. Form 2350 is not fixed to October 15. The IRS usually grants an extension to a date 30 days after you expect to meet your FEIE test. The Internal Revenue Manual confirms the standard 30 day window and notes a 90 day possibility when moving expense allocations apply.
No extension to pay. Even with Form 2350, your payment deadline remains the original due date. If you qualify for the automatic 2 month rule because you are out of the country, penalties for late payment are measured from that June date, but interest still runs from April. Paying what you reasonably expect to owe reduces interest and the chance of penalties.
Common pitfalls and simple fixes
- Treating 2350 like a generic extension. It is not. Use it only when you need time to meet FEIE tests. Otherwise, file Form 4868.
- Missing the filing date. File Form 2350 by your original due date, taking into account the automatic 2 month rule if you qualify. Late requests can be denied.
- Assuming e file is impossible. In 2025, many authorized platforms can transmit Form 2350. If yours cannot, mail it. Keep dated proof.
- Forgetting to pay. This is a filing extension only. Pay by the original deadline to reduce interest and protect against a late payment penalty.
- Picking the wrong 12 month window. The physical presence test lets you choose any 12 consecutive months. Choose the period that maximizes your exclusion and cleanly supports your dates.
FAQs
What exactly is IRS Form 2350?
It is an extension request you file when you expect to meet the FEIE tests after your regular due date. If approved, it lets you file after you qualify, usually 30 days beyond your qualifying date. It does not extend time to pay.
How is Form 2350 different from Form 4868?
Form 4868 is a six month, general extension to October 15 for most calendar year filers. Form 2350 is only for expats who need time to meet the bona fide residence or 330 day physical presence test. Both extend filing only, not payment.
Can I e file Form 2350?
In 2025, the IRS maintains an e file schema for Form 2350, which means authorized software can transmit it. If your provider does not support it, mail the paper form to the current Austin address listed in IRS instructions and keep proof of mailing.
Where do I mail Form 2350?
IRS instructions point to the Austin, Texas submission processing center. Recent IRS pages list Austin ZIPs 73301 0045 and 73301 0215 in different contexts. Use the address printed in the current year instructions you rely on and keep your proof of mailing or private delivery tracking.
What if I still will not meet a test by October 15?
That is what Form 2350 is for. If you need to meet a test after October, request a date 30 days past your expected qualifying date, and explain your dates clearly. IRS processors are instructed on longer than six month situations and how to evaluate 2350 requests.
