Returning to the US: Essential tax checklist for expats (2026)
Returning to the US after living abroad can be exciting, but the tax side of a mid-year move can get complicated fast. A returning to the US expat may need to deal with federal deadlines, partial-year exclusions, foreign accounts, state residency, and new health coverage decisions in the same filing cycle.
This expat tax checklist is updated for the 2025 tax year and the 2026 filing season. Whether you are an expat returning to the USA for work, family, or retirement, the goal is to help you move home with fewer surprises and a cleaner filing position.
If you are a US citizen returning from abroad, remember that the United States generally taxes you on worldwide income even while you live overseas. Relief tools such as the FEIE and the foreign tax credit can reduce double taxation, but they do not remove the filing requirement. Use this repatriation tax checklist before you move, again at year-end, and again before you file.
| Obligation | Form | Key threshold/deadline (2026) |
|---|---|---|
| Confirm residency status | Form 1040 | Green Card Test or Substantial Presence Test |
| Exclude foreign earned income | Form 2555 | Up to $130,000 per person for 2025, prorated if returning mid-year |
| Report foreign bank accounts | FinCEN Form 114 | Aggregate balance over $10,000 at any point during 2025 |
| Report foreign financial assets | Form 8938 | Single abroad: over $200,000 at year-end or over $300,000 at any time |
| Claim foreign tax credit | Form 1116 | Paid foreign taxes; unused credits generally can be carried back 1 year and forward 10 years |
| Health insurance | N/A | Federal ACA penalty = $0; state mandates may apply in CA, MA, NJ, RI, and Washington, D.C. |
| Filing deadline if abroad on April 15 | Form 1040 | If you qualify as out of the country on the regular due date, you generally get an automatic extension to June 15, 2026; tax due still generally must be paid by April 15, 2026 |
1. Confirm and update your residency status with the IRS
One of the first steps is to understand your US tax status. If you are a US citizen returning from abroad, you generally remain inside the US tax system because of citizenship-based taxation. If you are not a US citizen, the IRS looks to the Green Card Test or the Substantial Presence Test to determine whether you are a US tax resident.
For the 2025 income year, the Foreign Earned Income Exclusion (FEIE) allows you to exclude up to $130,000 of foreign-earned income, prorated if you return mid-year. For the 2026 income year (to be filed in 2027), the exclusion rises to $132,900.
Married couples where both spouses qualify can each exclude up to $130,000 for a combined exclusion of $260,000. The FEIE 2025 / $130,000 figure is the key exclusion amount for 2025 returns filed in 2026.
2. Don’t forget about state residency
For an expat returning to the USA, state tax residency can matter almost as much as federal residency. Each state has its own rules for domicile, part-year residence, and source income, so your move date, lease, home purchase, voter registration, and family ties can all matter.
During the year of repatriation to the US, you may need to file a part-year or nonresident state return. Research how your destination state treats pension income, capital gains, and foreign income before you move, because state rules do not always follow the federal rules.
3. Familiarize yourself with filing requirements and deadlines
The 2025/2026 filing season is usually straightforward once you know which deadline applies:
- April 15, 2026 – standard filing deadline for taxpayers living in the US
- June 15, 2026 – automatic extension if you were living abroad on April 15, 2026
- October 15, 2026 – additional extension available by filing Form 4868
Even when an extension gives you more time to file, interest generally starts running on unpaid tax from April 15. A returning to the US expat may also need Form 2555, Form 1116, and FinCEN Form 114, depending on income, credits, and foreign accounts.
4. Report all worldwide income
US citizens and residents must report worldwide income, no matter where it was earned. That can include foreign salary eligible for FEIE relief, dividends, interest, capital gains, rental income, self-employment income, and distributions from foreign retirement arrangements.
This expat tax checklist works best when you collect foreign tax returns, year-end statements, payroll records, and exchange-rate support before filing time.
In some noncitizen arrival or departure years, a dual-status return may apply instead of a full-year resident return.
5. Evaluate Social Security and retirement plan options
When you move back, review how foreign pensions, employer plans, and Social Security credits fit together. Totalization agreements can prevent double Social Security taxation and may help combine work credits for benefits.
If you contributed to a foreign retirement plan, check how future withdrawals will be taxed federally and by your new state, and review the options in our retirement planning guide for expats before making transfers or withdrawals.
6. Get health insurance or enroll in Medicare
Health coverage is easy to overlook during a move home, especially if you are leaving a country with a national health system. Your main options are usually employer-sponsored coverage, private insurance, Marketplace coverage, or Medicare if you are eligible.
- Employer-sponsored plans
- Private insurance
- Healthcare Insurance Marketplace plans
- Medicare, if eligible
If you are returning to the US from a foreign country, Marketplace special enrollment periods generally run for 60 days before or after the move. Over-65 taxpayers should also check Medicare enrollment timing carefully.
The ACA health insurance expat issue is no longer a federal tax penalty question, but state rules can still matter.
The federal ACA individual mandate penalty has been $0 since 2019. If you are moving to California, Massachusetts, New Jersey, Rhode Island, or Washington, D.C., a state-level mandate may still create a state tax penalty for non-coverage.
7. Manage foreign financial accounts and currency exchange
If your foreign financial accounts exceeded $10,000 in aggregate at any point during 2025, you must file an FBAR. In any FBAR returning expat situation, the obligation does not disappear just because you moved back to the United States before year-end.
A foreign account that holds only cryptocurrency is not currently reportable on the FBAR under FinCEN’s current notice, although that rule could change in the future. For Form 8938 (FATCA), the thresholds are higher for taxpayers who qualify as living abroad:
- single filers over $200,000 at year-end or over $300,000 at any time, and
- joint filers over $400,000 at year-end or over $600,000 at any time.
For taxpayers living in the US, the thresholds are:
- $50,000 and $75,000 for single filers, and
- $100,000 and $150,000 for joint filers.
Form 8938 / FATCA thresholds depend on the IRS living-abroad test, not only on where you were physically located on December 31.
8. Review employment changes and deferred compensation
An expat returning to the USA often sees compensation change at the same time as tax residency changes. Review tax equalization settlements, deferred compensation timing, bonuses, equity awards, vesting schedules, and stock options before year-end if possible.
Mid-year sourcing can affect whether income is treated as foreign-source or US-source, which in turn affects FEIE and foreign tax credit planning.
9. Plan for foreign property and asset management
If you keep property abroad after your move, remember that rental income, future sale proceeds, and related expenses may still need to be reported in the United States.
A returning US expat should keep records of purchase price, improvements, exchange rates, legal fees, and selling costs from day one. For deeper guidance, see our foreign property guide.
10. Claim moving expense deductions if eligible
The moving expense deduction is still suspended for most taxpayers. In general, only active-duty members of the Armed Forces moving under military orders because of a permanent change of station can claim it.
If you qualify, keep detailed records of transport, storage, and travel costs and use Form 3903 to calculate the deduction.
11. Update legal documentation and immigration status
Your return home should also trigger a practical paperwork review. Update licenses, insurance, estate planning documents, and any professional registrations that changed while you were abroad.
If family members are not US citizens, make sure their immigration status and entry documents line up with your move timeline and employment plans.
12. Coordinate with your employer on exit paperwork
If you are ending an overseas assignment, use this repatriation tax checklist to close out employer-side items before the move.
That can include tax equalization settlements, gross-up calculations, pension treatment, equity compensation records, final foreign payroll reporting, and benefit transitions. Clean paperwork here can prevent missing income statements and sourcing disputes later.
13. Use streamlined filing to catch up on expat taxes
If you fell behind while living abroad, the IRS streamlined filing compliance procedure may help you catch up. Eligible taxpayers generally file up to 3 years of overdue returns and up to 6 years of FBARs and must certify that the failure to file was non-willful.
For a streamlined filing expat who is moving back now, it often makes sense to clean up older filings before the next current-year return is prepared.
14. Assess the tax implications of a mid-year return
A mid-year move creates the technical issues that most often get missed in an expat tax checklist:
- FEIE eligibility based on qualifying days abroad
- foreign tax credit carryover rules and whether unused credits can still help in later years
- state tax residency and foreign income sourcing
- healthcare coverage requirements, noting that the federal ACA penalty is $0 while state mandates vary
If you paid foreign taxes before returning, a foreign tax credit carryover may still offset future US tax on foreign-source income. Some noncitizens who changed status during the year may also need a dual-status return instead of a standard full-year resident filing.
15. Seek professional guidance
An expat returning to the USA with foreign accounts, deferred compensation, pensions, or part-year FEIE calculations can save a lot of time by getting the structure right before filing.
Professional help can confirm residency status, compare FEIE against the foreign tax credit, check FBAR and FATCA reporting, and identify state filing risks.
Conclusion
Returning home is easier when you deal with tax issues early instead of after the move. For a US citizen returning from abroad or any returning to the US expat with foreign income, accounts, or pensions, the key is to line up residency, reporting, deadlines, and state rules before filing season.
Tax thresholds and rules change annually – this checklist is updated for the 2025 tax year and the 2026 filing season.
This expat tax checklist is educational and meant to help you spot issues early. Your exact result can still depend on treaty positions, state residency, filing status, and the timing of your move.
FAQ
Yes, in many cases. A US citizen returning from abroad generally still has to file if they meet the normal filing thresholds, because US taxation usually follows citizenship and worldwide income rules. Relief such as FEIE or the foreign tax credit can reduce double taxation, but it does not remove the filing requirement. In some noncitizen cases, a dual-status return may apply.
The Foreign Earned Income Exclusion limit for the 2025 tax year is $130,000 per qualifying individual. If you returned mid-year, the exclusion is prorated based on qualifying days abroad. Married couples where both spouses qualify can each claim the exclusion for a combined total of $260,000. FEIE 2025 / $130,000 is the number most returning filers need to check first.
Yes. If your foreign bank and financial accounts exceeded $10,000 in aggregate at any point during 2025, you must file FinCEN Form 114 by April 15, 2026, with an automatic extension to October 15, 2026. For any FBAR returning expat case, the filing rule applies even if you already moved back before year-end.
The federal ACA individual mandate penalty has been $0 since 2019, so there is no federal shared responsibility payment on your federal return. The ACA health insurance expat question still matters at the state level, though. California, Massachusetts, New Jersey, Rhode Island, and Washington, D.C. have their own active coverage rules and potential penalties.
Form 8938 thresholds depend on your filing status and whether you meet the IRS living-abroad test. If you qualify as living abroad, the threshold is more than $200,000 at year-end or $300,000 at any time for unmarried or married-filing-separately taxpayers, and more than $400,000 at year-end or $600,000 at any time for joint filers. If you do not qualify as living abroad, the threshold is more than $50,000 at year-end or $75,000 at any time for unmarried or married-filing-separately taxpayers, and more than $100,000 at year-end or $150,000 at any time for joint filers.
Yes. If you paid foreign taxes on foreign-source income during the year, you may still claim the Foreign Tax Credit on Form 1116. A foreign tax credit carryover can also remain valuable after you move back, because unused credits can generally be carried back 1 year and forward 10 years, subject to category rules and exceptions, and may offset future US tax on foreign-source income.
The IRS streamlined procedure allows eligible taxpayers to catch up on overdue filings if the failure to file was non-willful. A streamlined filing expat submission generally includes 3 years of tax returns and 6 years of FBARs. It can be one of the most effective ways to come back into compliance before or after a move home.
If you qualify as out of the country on the regular due date, you generally get an automatic extension to June 15, 2026 to file your 2025 return. Interest still runs on unpaid tax from April 15, 2026. If you need more time to file, submit Form 4868 by June 15, 2026 for an additional extension to October 15, 2026. If you need extra time to qualify for the FEIE tests, review Form 2350.
