Returning to the United States after years abroad creates a compressed window of tax decisions, many of which interact with reporting obligations you may have missed while overseas. The IRS has become increasingly aggressive about foreign account enforcement, with penalties that can exceed the account balances themselves. This action plan sequences the steps so you address the highest-risk items first and avoid compounding mistakes.

The Critical Path

Start with compliance -- getting current on filings -- before optimizing. The penalties for unfiled foreign account reports are so severe that they dwarf any tax savings from other strategies.

Your Repatriation Tax Action Plan
1
Understand your ongoing US tax obligations
Before returning
US citizens and green card holders are taxed on worldwide income regardless of where they live. This is true even if you have lived abroad for decades, even if you paid foreign taxes, and even if you earned no US-source income. Many expats incorrectly believe that living abroad exempts them from US filing requirements. It does not. If your gross income exceeds the filing threshold (approximately $14,600 for single filers in 2026), you must file a US return every year.
2
Assess whether you have unfiled returns and choose a compliance path
6-12 months before return
If you have unfiled US tax returns, you have two primary options. The Streamlined Filing Compliance Procedures are available if your failure to file was non-willful (not intentional). You file the last 3 years of income tax returns and 6 years of FBARs, and pay any tax and interest owed. The penalty is 5% of the highest aggregate balance in unreported foreign accounts (waived entirely if you lived abroad). If willfulness is a concern, the IRS Voluntary Disclosure Practice offers more protection but with higher penalties. Choosing the wrong path can be catastrophic -- consult a CPA or tax attorney before filing anything.
3
Report all foreign financial accounts via FBAR
By April 15 (auto-extension to October 15)
If the aggregate value of your foreign financial accounts exceeded $10,000 at any point during the year, you must file FinCEN Form 114 (FBAR) electronically. This includes bank accounts, brokerage accounts, mutual funds, and any account in which you have signatory authority. The FBAR is filed separately from your tax return through the BSA E-Filing System. Willful failure to file carries penalties up to the greater of $100,000 or 50% of the account balance per violation. Even non-willful penalties are $10,000 per account per year.
4
File FATCA reporting on Form 8938
With your tax return
The Foreign Account Tax Compliance Act requires separate reporting of specified foreign financial assets on Form 8938, filed with your tax return. Thresholds depend on filing status and whether you live abroad or in the US. For US residents filing jointly, the threshold is $100,000 at year-end or $150,000 at any point during the year. For those living abroad, thresholds are higher ($400,000/$600,000 MFJ). FATCA and FBAR have overlapping but not identical requirements -- most expats must file both.
5
Claim foreign tax credits or the Foreign Earned Income Exclusion
On your tax return
To avoid double taxation, you can claim either the Foreign Earned Income Exclusion (FEIE, Form 2555) or foreign tax credits (Form 1116), but the choice has long-term implications. The FEIE excludes up to $132,900 (2026) of foreign earned income from US tax, but once revoked, you cannot re-elect it for five years. Foreign tax credits offset US tax dollar-for-dollar against taxes paid to foreign governments and often provide greater benefit for high-income earners. A CPA should model both options for your specific situation, because the optimal choice depends on your income level, the foreign country's tax rate, and your plans after returning.
6
Address foreign retirement accounts and pensions
Before and during transition year
Foreign retirement accounts (UK SIPPs, Australian superannuation, Canadian RRSPs, etc.) create complex US tax issues. Many foreign retirement plans are not recognized as tax-deferred under US law, meaning the annual growth may be taxable in the US even if it is tax-free in the foreign country. Some foreign pensions are covered by tax treaties that provide relief. Others may be classified as foreign trusts requiring Form 3520 and Form 3520-A reporting, with penalties of $10,000 or 35% of the gross reportable amount for non-filing. Determine the US tax treatment of every foreign retirement account before you return.
7
Handle foreign currency gains and losses
During transition year
Under IRC 988, gains and losses from foreign currency transactions are generally treated as ordinary income or loss, not capital gains. This includes gains from converting foreign currency holdings to US dollars, gains on the sale of foreign-currency-denominated assets, and even gains embedded in everyday transactions when the exchange rate moves between the time you earn income and the time you convert it. If you are liquidating foreign accounts to repatriate funds, the currency conversion itself can generate a taxable event.
8
Plan the transition year carefully
The calendar year of your return
The year you return to the US is typically the most complex tax year of your life. You may need split-year treatment for the Foreign Earned Income Exclusion (prorating the exclusion for the portion of the year you lived abroad). You must establish state tax residency, which varies by state -- some states assert residency from the day you arrive, others use a 183-day rule, and a few (like California) have aggressive lookback provisions. Coordinate the timing of your return with income recognition, foreign account liquidation, and any moving expenses to minimize the overall tax impact.
## Key Deadlines

The FBAR deadline is the one most expats miss, and its penalties are the most severe in the entire individual tax system.

Critical Deadlines for Returning Expats
April 15
FBAR filing (FinCEN 114)
Report foreign accounts exceeding $10,000 aggregate value -- auto-extension to October 15
April 15
Individual tax return
File Form 1040 with Schedules B, Forms 8938, 1116 or 2555 -- extension to October 15 available
June 15
Automatic expat extension
US citizens living abroad get an automatic 2-month extension to June 15 (interest still accrues)
October 15
Extended FBAR deadline
Final deadline for FBAR filing -- no further extensions available
Ongoing
Streamlined procedures
No deadline to enter the Streamlined Filing Compliance Procedures, but the program could be closed at any time
Year of return
State residency establishment
Triggers state filing obligations -- timing affects which state claims your income
## Common Mistakes
Warning

Do not file amended or delinquent returns on your own without professional guidance. If you have unfiled returns and unreported foreign accounts, filing outside of a formal compliance program (Streamlined Procedures or Voluntary Disclosure) forfeits your ability to use those programs later. Once the IRS contacts you, the Streamlined Procedures are no longer available. The order in which you file matters, and the certifications you sign carry perjury penalties.

Warning

Do not assume a tax treaty eliminates your US filing obligation. Tax treaties may reduce the tax you owe, but they almost never eliminate the requirement to file a US return, FBAR, or Form 8938. Treaty-based positions must be disclosed on Form 8833, and failing to disclose can result in penalties even if the treaty position is correct. The filing obligation and the tax obligation are separate issues.

Tip

If you have lived abroad for the entire year and have unfiled returns, the Streamlined Foreign Offshore Procedures waive all penalties -- the 5% miscellaneous offshore penalty is reduced to zero for qualifying foreign residents. This makes the cost of coming into compliance significantly lower than most expats expect. The key requirement is that your failure to file was non-willful, meaning it resulted from negligence, inadvertence, or misunderstanding of the law rather than intentional avoidance.
