Repatriation of Funds: Tax Rules, FBAR, and Form 8938

The tax rules on repatriation of funds turn on a distinction most people miss: the U.S. taxes the income when you earn it, not when you move the money home. If you are a U.S. citizen, green card holder, or resident alien, your worldwide income was reportable on the federal return for the year it was earned, so a later wire transfer from your foreign bank generally creates no new income tax.¹ What the transfer can trigger is a separate set of reporting obligations, and the penalties for missing those forms are where the real financial damage happens.

The Income Was Taxable Before the Wire

The United States taxes citizens and residents on worldwide income regardless of where it was earned.¹ Salary from an overseas employer, rent from foreign property, gains on foreign investments — all of it is taxable in the year earned, not the year you bring it home.

A common assumption is that leaving money abroad defers the tax. It does not. If you sold real estate in London in 2024 and wired the proceeds to your U.S. bank in 2026, the capital gain belonged on your 2024 return. The 2026 wire itself creates no additional income tax. It can, however, push your foreign account balances over reporting thresholds that year, or trigger source-of-funds questions from the receiving bank. Keep the two ideas separate: income taxability is one issue, and the transfer is another.

FBAR and Form 8938: Two Separate Reports

Foreign accounts are caught by two overlapping reporting regimes. Meeting one threshold does not excuse the other, and the most common error is assuming a single filing covers both.

FBAR (FinCEN Form 114)

If the combined value of all your foreign financial accounts exceeds $10,000 at any point during the calendar year, you must file a Report of Foreign Bank and Financial Accounts with the Financial Crimes Enforcement Network.² The threshold is cumulative across accounts: two accounts at $6,000 each means both get reported. The FBAR is filed separately from your tax return, electronically through FinCEN’s BSA E-Filing System, and is due April 15 with an automatic extension to October 15.³

Form 8938 (FATCA)

The Foreign Account Tax Compliance Act requires a separate disclosure of specified foreign financial assets on Form 8938, which attaches to your income tax return. Thresholds are higher than the FBAR and depend on filing status and where you live:

Unmarried, living in the U.S.: total value exceeds $50,000 on the last day of the tax year or $75,000 at any point during the year.
Married filing jointly, living in the U.S.: exceeds $100,000 on the last day or $150,000 at any point.
Unmarried, living abroad: exceeds $200,000 on the last day or $300,000 at any point.
Married filing jointly, living abroad: exceeds $400,000 on the last day or $600,000 at any point.

These thresholds were last confirmed by the IRS in September 2025.³ FBAR and Form 8938 cover overlapping but not identical categories of assets, so if you cross both thresholds you file both.⁴

Foreign Gifts and Inheritances (Form 3520)

Money coming from a foreign relative or estate has its own rule. If you receive a gift or inheritance from a foreign person and the total from that person exceeds $100,000 in a tax year, you must file Form 3520.⁵ The deadline is April 15 for calendar-year individuals, subject to any extension on your income tax return.

Foreign gifts are generally not taxable income, but the reporting is mandatory, and the penalty for a late or missed form is 5% of the gift amount for each month the form is late, capped at 25%.⁶ On a $500,000 inheritance, that ceiling is $125,000 in penalties on a form that reports no taxable income at all. The scale of the penalty is what makes this the easiest expensive mistake to make.

Avoiding Double Taxation With the Foreign Tax Credit

When the country where you earned the income has already taxed it, the foreign tax credit prevents you from paying tax twice on the same dollars. Individuals claim the credit on Form 1116, and corporations use Form 1118.⁷

There is a shortcut for straightforward situations. If all of your foreign-source income is passive (interest and dividends), the taxes were reported to you on Form 1099 or Schedule K-3, and your total creditable foreign taxes are $300 or less ($600 on a joint return), you can claim the credit directly on your return without filing Form 1116.⁸ Above those figures, Form 1116 is required. The credit is capped at the U.S. tax attributable to the foreign-source income, so foreign taxes on one type of income cannot offset U.S. tax on domestic income.

Tax treaties between the United States and dozens of other countries can reduce withholding rates at the source. When a treaty country withholds at the reduced rate, you claim a credit for the amount actually withheld. The treaty does not remove the requirement to report the income; it lowers the combined tax you pay.

What Your Bank Will Ask For

Banks on both ends of the transfer will want proof of where the money came from. This is an anti-money-laundering obligation, not a courtesy, and thin documentation is the most common reason transfers get held for weeks. The specifics depend on how the money was earned or received:

Property sales: certified sale deed or closing statement, proof of ownership, and records of the original purchase price and any improvements.
Employment income: employment contracts, pay stubs, and bank statements showing regular salary deposits.
Investments: brokerage statements showing the purchase, any dividends, and the sale proceeds.
Inheritance: probate documents, death certificate, solicitor correspondence, and tax clearance from the originating jurisdiction.
Business proceeds: ownership records, financial statements, and documentation of the transaction that generated the funds.

For transfers above roughly $100,000 to $150,000, expect enhanced due diligence from the receiving bank. That often means several years of tax returns, bank statements, and employment records, not just the paperwork for the specific transaction. Once a transfer is flagged, the bank will not release funds until every follow-up question is answered, so having the file ready before you initiate the wire matters more than any speed you might gain by rushing.

Many source countries impose their own clearance requirements. The sending jurisdiction may require a certificate from a local tax professional confirming that all domestic tax obligations on the funds have been met before the remittance can proceed. Check with the foreign bank or a local tax advisor before initiating the outbound transfer.

The Bank’s Own Filings: CTR and SAR

Banks handling your transfer have mandatory filings of their own that can affect how the process feels from your side.

Any cash transaction over $10,000 (deposit, withdrawal, or exchange) requires the bank to file a Currency Transaction Report with FinCEN.⁹ Multiple cash transactions adding up to more than $10,000 in a single day trigger the same filing.¹⁰ The filing is automatic on the bank’s side. You should not split transactions to stay under the threshold. Structuring is a federal crime carrying up to five years in prison and fines up to $250,000.

Banks must also file Suspicious Activity Reports when transactions raise flags. The thresholds are lower than most people expect: $5,000 when the bank can identify a possible suspect, and $25,000 when no suspect is identifiable.¹¹ For suspected money laundering, the threshold drops to $5,000 whether or not a suspect is identified. You will not be told a SAR was filed; banks are prohibited from telling you. Clean documentation and normal transaction patterns are the way to avoid delays.

The Penalties Are Where the Damage Happens

The penalties in this area are disproportionate to what most people expect, especially because some of the forms involve no additional tax at all.

FBAR

A non-willful failure carries a maximum civil penalty of $10,000 per violation (adjusted annually for inflation), and it can apply per account, per year.¹² For willful violations, the ceiling jumps to the greater of $100,000 or 50% of the account balance at the time of the violation, and criminal prosecution becomes possible. A reasonable cause exception is available where the failure was not willful neglect and the account balance was properly reported.

Form 8938

Failing to file triggers a $10,000 penalty. If you still have not filed 90 days after the IRS mails a notice, an additional $10,000 accrues for each 30-day period the failure continues, up to a $50,000 maximum.¹³ Married couples filing jointly are jointly and severally liable, so the IRS can collect the full amount from either spouse.¹⁴

Form 3520

The penalty is 5% of the gift or inheritance amount per month, capped at 25%.⁶ Because the penalty scales with the reported amount rather than a flat figure, it grows quickly on large inheritances. Reasonable cause exceptions exist across all three regimes, but the burden is on you to show why the failure was not willful neglect.

If You Are Also Renouncing Citizenship

Repatriation as part of renouncing U.S. citizenship or surrendering a long-term green card brings an additional tax. Under Section 877A, the IRS treats a covered expatriate as if they sold all worldwide assets at fair market value on the day before expatriation.¹⁵ You are a covered expatriate if any one of these applies:

Your average annual net income tax over the five years before expatriation exceeds a specified threshold ($206,000 for 2025, adjusted annually for inflation).
Your net worth is $2 million or more on the date of expatriation.
You fail to certify on Form 8854 that you have complied with all federal tax obligations for the preceding five years.

A portion of the mark-to-market gain is excluded. For 2025 the exclusion was $890,000, adjusted annually.¹⁶ Gain above that is taxed as if realized, even though nothing was actually sold. Planning before you initiate expatriation is where any savings are found; retroactive fixes after Form 8854 is filed are essentially impossible.

Crypto on Foreign Exchanges

Digital assets held on foreign exchanges sit in a partly settled area of the reporting framework. Under FinCEN Notice 2020-2, virtual currency held in a foreign account is not by itself a reportable account type for FBAR purposes, unless the same account also holds reportable assets such as cash or securities.¹⁷ FinCEN has signaled an intent to expand FBAR to cover virtual currency, but no final rule has been published as of early 2026.

The income side is settled: gains from selling or exchanging cryptocurrency are taxable in the year realized, wherever the exchange is located. If you convert crypto on a foreign platform and wire the fiat proceeds to a U.S. bank, the capital gain was taxable when you sold, and the resulting fiat balance may push you over the FBAR or Form 8938 thresholds even if the crypto itself was not reportable. Cost basis tracking across foreign platforms is essential, because the IRS expects the same gain-and-loss reporting it expects on any other investment.
