How do I request a tax extension while living abroad?
If you’re wondering how to request a tax extension while living abroad, you may already have extra time automatically. Qualifying US citizens and resident aliens abroad generally get until June 15, 2026 to file their 2025 federal tax return.
The normal deadline for a 2025 federal tax return is April 15, 2026. However, qualifying US citizens and resident aliens living abroad generally receive an automatic extension until June 15.
You don’t normally need to file Form 4868 to get this first extension. When you file your return, you include a short statement explaining which overseas condition qualified you for it.
If June 15 still doesn’t give you enough time, you can usually file Form 4868 to extend the filing deadline further to October 15.
This extra time can be particularly useful when the country you live in follows a different tax year. Australia is a good example because its usual income year runs from July 1 to June 30, meaning the Australian year may not even be finished when the June US deadline arrives.
One thing to remember is that having more time to file does not stop interest from building on unpaid US tax. Qualifying taxpayers abroad can have until June 15 to file and pay, but interest on unpaid federal income tax generally runs from April 15.

When is my US tax return deadline if I live abroad?
For most calendar-year taxpayers, the normal deadline is April 15, but qualifying taxpayers living abroad automatically get two extra months.
If you are a US citizen or resident alien, you generally qualify for the automatic extension if, on April 15:
- you are living outside the United States and Puerto Rico, and your main place of business or post of duty is also outside the United States and Puerto Rico; or
- you are serving in the military or naval service on duty outside the United States and Puerto Rico.
If either condition applies, your filing deadline generally moves from April 15 to June 15, 2026.
Simply being on holiday outside the United States on April 15 is not enough. The extension is based on your living and work circumstances, not just where you happen to be on deadline day.

Do I need to apply for the June 15 extension?
No. If you qualify, the first two-month extension is automatic.
You do not file Form 4868 just to move your deadline from April 15 to June 15.
The IRS does require a short statement with the return explaining which overseas condition qualified you for the extension.
That statement does not need to be complicated. For example:
Taxpayer qualifies for the automatic two-month extension because they lived outside the United States and Puerto Rico and their main place of business was outside the United States and Puerto Rico on April 15, 2026.
The important point is that you are telling the IRS why the automatic overseas extension applies.
Need more time to file your US taxes from abroad?
When should I file Form 4868?
If June 15 still isn’t enough time. Form 4868 can generally extend your filing deadline to October 15.
This is common for Americans living abroad who are waiting for foreign tax documents, income statements, or other information that is not ready by June.
If you qualified for the automatic two-month extension, Form 4868 generally needs to be filed by June 15, 2026.
When completing Form 4868, make sure line 8 is checked to show that you are a US citizen or resident who is out of the country.
Unlike the first two-month extension, the additional extension to October is an extension of filing time only. It does not give you extra time to pay.
How do I apply for the October extension?
You request the October extension by filing Form 4868.
Form 4868 is the IRS application for an automatic extension of time to file an individual income tax return.
For an expat already using the automatic June deadline:
- estimate your US tax liability as accurately as you can;
- file Form 4868 by June 15;
- check line 8 to indicate that you are out of the country; and
- pay as much of your expected US tax as possible.
You can generally file the extension electronically or by mail. The IRS also allows extensions to be filed through its electronic filing options
Does a tax extension give me more time to pay?
Not in the same way that it gives you more time to file.
This is where many expats get caught out.
The automatic two-month overseas extension does give qualifying taxpayers until June 15 to file and pay. However, the IRS still charges interest from April 15 on any federal income tax that was unpaid on that date.
There is a useful distinction with the late-payment penalty.
For taxpayers who qualify for the automatic overseas extension, late-payment penalties are generally measured from June 15, while interest still runs from April 15.
The extension from June to October is different. That additional four months extend the time to file, not to pay.
If you expect to owe US tax, estimating and paying as much as possible earlier can therefore help reduce interest and possible penalties.
Can I get more time after October 15?
Possibly, but this extra extension is not automatic.
Taxpayers who are considered “out of the country” may request an additional discretionary two-month filing extension, taking the deadline to December 15 for a calendar-year return.
To request it, you need to send the IRS a letter by October 15 explaining why you need the additional time.
You normally will not receive a letter approving the request. The IRS contacts you if the request is denied.
Because this extension is discretionary, it should not be treated as the standard filing deadline for Americans abroad.
It is also not available if you have already received an approved extension under Form 2350.
What is Form 2350 and when would I use it?
Form 2350 is for certain taxpayers who need more time to meet the bona fide residence test or physical presence test before claiming the Foreign Earned Income Exclusion.
You may need Form 2350 if you expect to qualify for the:
- bona fide residence test; or
- physical presence test,
but you will not meet the relevant test by your normal filing deadline.
This matters because those tests can be used to qualify for the Foreign Earned Income Exclusion and foreign housing exclusion or deduction.
If approved, the IRS generally allows the extension until about 30 days after the date you reasonably expect to qualify.
For example, suppose you moved abroad late in 2025 and expect to qualify under the physical presence test.
You may not yet have accumulated the required 330 full days in foreign countries during a 12-month period by June 15, 2026.
Form 2350 may allow you to wait until you meet the test before filing and claiming the exclusion.
Like other extensions, this does not remove interest that may apply to unpaid tax.
Does the federal extension cover my FBAR?
No. The FBAR has its own extension rules.
The FBAR is normally due on April 15.
If you miss that deadline, FinCEN automatically gives you until October 15 to file. You do not need Form 4868, and you do not have to submit a separate FBAR extension request.
So even though the FBAR and an extended Form 1040 can both end up due on October 15, they arrive there under different rules.
Does Form 4868 extend Form 3520?
It can, but Form 3520 has its own rules and should not simply be treated as part of Form 1040.
For an individual taxpayer who qualifies under the overseas rules, Form 3520 can generally also be due June 15. You must include a statement with Form 3520 showing that you meet the applicable overseas condition.
If you receive an extension for your individual income tax return, Form 3520 can generally be extended to October 15 for a calendar-year taxpayer.
However, the discretionary December extension for Form 1040 does not push Form 3520 past October 15.
That distinction is worth checking carefully if foreign trusts or certain large foreign gifts are part of your filing.
Does my Form 1040 extension cover Form 3520-A?
Usually not. Form 3520-A has its own deadline, which is where things can get a little confusing.
This is one of the more common extension traps for Americans abroad.
If a foreign trust files Form 3520-A separately, extending your personal Form 1040 will not extend the trust return.
The trust generally needs to request its own extension using Form 7004 under the foreign trust’s EIN
There is an important exception if a US owner files a substitute Form 3520-A with Form 3520. In that situation, the substitute Form 3520-A follows the Form 3520 due date.
What about my state tax return?
Your federal extension does not necessarily settle your state filing deadline.
Each state has its own rules.
Some states recognise a federal extension automatically. Others may require a separate extension, payment, or state-specific action.
If you still have a state filing obligation while living abroad, check the rules for that particular state rather than assuming Form 4868 covers everything.
What happens if I do not apply for an extension on time?
If you need an extension, missing the deadline can leave you with a late return rather than simply giving you another chance to extend later.
If you do not qualify for the automatic overseas June deadline, Form 4868 would normally need to be filed by April 15.
If you do qualify for the June deadline, the request for additional time through Form 4868 generally needs to be made by June 15.
A late Form 4868 does not normally create a retroactive extension.
If the deadline has already passed, continuing to wait rarely improves the situation.
Possible consequences can include:
- late-filing penalties;
- late-payment penalties;
- interest on unpaid tax; and
- separate penalties for overdue international information returns.
The exact result depends on what was due, whether tax remains unpaid, and whether you have reasonable cause for filing late.
How should I handle an extension if I live abroad?
A practical approach is to check whether you qualify for the June 15 deadline first. Estimate any US tax you may owe and pay as much as reasonably possible.
If you still need more filing time, submit Form 4868 by June 15 and check line 8. Use the extra time to gather missing foreign income records, tax assessments, and investment statements.
Also check your other deadlines separately. FBAR, Form 3520, Form 3520-A, business returns, and state returns do not all follow exactly the same extension rules.
