Key tax deadlines for U.S. expats in 2027

Tax filing deadlines

April 15, 2027: the standard deadline to file your 2026 U.S. federal tax return and pay any tax owed.
June 15, 2027: if you live and have your main place of business outside the U.S. and Puerto Rico on the regular due date, you get an automatic two-month extension to file and pay. Attach a statement to your return explaining that you qualify. Interest still runs from April 15.

Extensions:

October 15, 2027: file IRS Form 4868 by the regular (or June 15) deadline to extend filing to October 15, 2027.
December 15, 2027: if you live abroad, you can ask for a further extension to December 15 by sending the IRS a written request before October 15. It isn't automatic.

While extensions grant more time to file your tax return, any taxes owed are still due by April 15, 2027. Interest and penalties may accrue on unpaid taxes from this date.

Estimated tax payments

If you expect to owe at least $1,000 in tax for the year after subtracting withholding and refundable credits, you generally need to make quarterly estimated tax payments. The remaining payment for the 2026 tax year is due January 15, 2027. For the 2027 tax year, payments are due:

1st quarter: April 15, 2027
2nd quarter: June 15, 2027
3rd quarter: September 15, 2027
4th quarter: mid-January 2028 (check the IRS calendar for the exact date)

Making timely estimated tax payments helps avoid underpayment penalties.

FBAR and FATCA deadlines

FBAR (Foreign Bank Account Report):

Deadline: April 15, 2027 (for 2026 accounts), with an automatic extension to October 15, 2027.
Requirement: If you have foreign financial accounts totaling over $10,000 at any time during the year, you must file FinCEN Form 114 electronically through the BSA E-Filing System.

FATCA (Foreign Account Tax Compliance Act):

Deadline: Aligns with your federal tax return deadlines, including extensions.
Requirement: Form 8938 must be filed if you have specified foreign financial assets exceeding certain thresholds (which vary based on filing status and residency).

State tax considerations for U.S. expats

While federal taxes are a primary concern for U.S. expats, state taxes can also significantly impact your overall tax burden. Understanding your state tax obligations is crucial for effective financial planning.

Here’s how different states handle taxation for expatriates:

If you’re domiciled in a zero income tax state

If your domicile—or your last state of residency before moving abroad—is one of the states with no state income tax, you’re generally not required to pay state income tax while living abroad.

These states are:

Alaska
Florida
Nevada
New Hampshire (no tax on interest and dividends since 2025)
South Dakota
Tennessee
Texas
Washington (taxes large capital gains)
Wyoming

Being domiciled in a zero-income tax state simplifies your tax obligations, as you won’t owe state income tax on your earnings, regardless of where you live or work abroad.

States that don’t tax non-residents even if domiciled there

Some states do not tax individuals considered non-residents for tax purposes, even if they maintain domicile there. This means that if you’ve moved abroad and meet the state’s criteria for non-residency, you generally won’t be subject to state income tax on your worldwide income.

States in this category include:

Important Considerations:

Residency vs. Domicile: While you may still be domiciled in the state, establishing non-residency for tax purposes typically involves meeting specific criteria, such as spending less than a certain number of days in the state and severing significant ties.
Maintain Documentation: Keep thorough records proving your non-residency status to present to state tax authorities if needed.
Key Takeaway: If you establish non-residency while being domiciled in these states, you generally won’t owe state income tax on your foreign-earned income.

States that tax domiciled Americans on worldwide income

Several states tax residents on their worldwide income regardless of where they live or earn their income.

If you’re domiciled in one of these states, you may be subject to state income tax even while living abroad.

Characteristics of these states:

Strict residency rules: These states have stringent definitions of residency and domicile, making it challenging to break tax ties.
Worldwide income taxation: Residents are taxed on all income, including foreign-earned income, often without the benefit of exclusions like the federal Foreign Earned Income Exclusion (FEIE).

What this means for expats:

Potential double taxation: You may face state taxes on top of federal taxes, increasing your overall tax liability.
Limited relief: Many of these states do not allow for the FEIE or a foreign tax credit at the state level.
Complex compliance: Navigating tax obligations in these states can be complicated and may require professional assistance.

Foreign Earned Income Exclusion for 2026

Exclusion amount

For the 2026 tax year (filed in 2027), the Foreign Earned Income Exclusion (FEIE) amount is $132,900, up from $130,000 for 2025 and $126,500 for 2024.

This adjustment accounts for inflation and allows qualifying expats to exclude a higher amount of foreign-earned income from U.S. taxation.

Eligibility requirements

To qualify for the FEIE, you must meet one of the following tests:

Bona Fide Residence Test:

You are a bona fide resident of a foreign country or countries for an uninterrupted period that includes an entire tax year.
Establishing residency involves demonstrating intent to stay, such as obtaining residency permits, leasing or purchasing a home, and integrating into the local community.

Physical Presence Test:

You are physically present in a foreign country or countries for at least 330 full days during any consecutive 12-month period.
The 330 days do not need to be consecutive but must fall within a 12-month frame.

Key changes in tax laws affecting expats for 2025 and 2026

Increase in Foreign Earned Income Exclusion (FEIE)

The FEIE is $130,000 for the 2025 tax year and $132,900 for 2026. These increases help expatriates reduce their taxable income and potentially lower their U.S. tax liability, mitigating the risk of double taxation on foreign-earned income.

Adjustments to standard deductions

The One Big Beautiful Bill Act raised the standard deduction starting with 2025. For the 2026 tax year, it is:

Single filers: $16,100 ($15,750 for 2025)
Married filing jointly: $32,200 ($31,500 for 2025)
Head of household: $24,150 ($23,625 for 2025)

These adjustments may affect your overall taxable income and should be considered when planning your tax strategy.

Child Tax Credit increase

The Child Tax Credit is $2,200 per qualifying child under 17 for 2025 and 2026, with up to $1,700 refundable. This can provide significant tax savings for expat families who meet the eligibility criteria.

Other changes from the One Big Beautiful Bill Act

Senior deduction: an extra deduction of up to $6,000 per person aged 65 or older for 2025 through 2028, phasing out above $75,000 of modified AGI ($150,000 for joint filers).
SALT cap: the cap on deducting state and local taxes rose to $40,000 for 2025 ($40,400 for 2026), reduced for incomes above $500,000.
Estate and gift tax: the basic exclusion is $15 million per person from 2026, now permanent and indexed for inflation.
Remittance transfer tax: from January 1, 2026, a 1% federal tax applies to money transfers abroad funded with cash, money orders, cashier's checks or similar instruments.

Automatic filing extensions

U.S. expatriates who live and work outside the U.S. and Puerto Rico receive an automatic two-month extension to file their tax returns, moving the deadline to June 15, 2027 for 2026 returns. If additional time is needed, they can file Form 4868 to extend to October 15, 2027.

Important tax forms for expats

Form 1040: U.S. Individual Income Tax Return

The primary form for reporting your income, deductions, credits, and tax liability.

Form 2555: Foreign Earned Income Exclusion

Used to claim the FEIE and exclude up to $132,900 of foreign-earned income for 2026 ($130,000 for 2025).
Requires information on residency status and foreign income details.

Form 1116: Foreign Tax Credit

Allows you to claim a credit for taxes paid to a foreign country, reducing your U.S. tax liability.

Deadline

Due by April 15, 2027 (for 2026 accounts), with an automatic extension to October 15, 2027.

Penalties for non-compliance

Failure to file the FBAR can result in significant penalties, including fines up to $10,000 per violation for non-willful violations, and higher penalties or criminal charges for willful violations.

Consequences of missing deadlines

Late Filing Penalties: The IRS may impose penalties for failing to file tax returns or required forms by the deadline, including extensions.
Interest on Unpaid Taxes: Interest accrues on any unpaid tax from the original due date (April 15, 2027 for 2026 returns) until the date of payment.
Impact on Benefits and Exclusions: Missing deadlines may result in the loss of eligibility for certain benefits, such as the FEIE, potentially increasing your tax liability.
