Whether you owe tax on money transferred from overseas to the US depends on what the money represents, not on the fact that it crossed a border. Wages, business profits, rent, interest, dividends, and investment gains are taxable to US citizens and resident aliens no matter where they were earned. Gifts, inheritances, legitimate loans, and movements of your own savings are not taxable at all. Some of those non-taxable transfers still have to be reported to the IRS, and the penalties for missing those reports are severe even when no tax is owed.
What Determines Whether a Transfer Is Taxed
Federal law defines gross income as “all income from whatever source derived.”1Office of the Law Revision Counsel. 26 U.S. Code 61 – Gross Income Defined Those last three words mean geography is irrelevant. A consulting fee earned in Germany is taxed the same as one earned in Georgia. The IRS looks at the economic character of what you received, not the routing of the wire.2Internal Revenue Service. Reporting Foreign Income and Filing a Tax Return When Living Abroad
You also can’t defer tax by keeping the money offshore. Under the constructive receipt rule, income is taxable in the year it becomes available to you, not the year you finally transfer it stateside.3eCFR. 26 CFR 1.451-2 – Constructive Receipt of Income If a foreign employer credits your salary in November, it’s taxable that year, even if the wire to your US bank happens in January.
Transfers That Are Not Taxable
Three categories of incoming money do not create federal income tax, no matter how large. A fourth situation, moving your own funds, is not a transfer of new income at all.
Gifts From a Foreign Person
Money received as a genuine gift is excluded from the recipient’s gross income under federal law, without any dollar limit.4Office of the Law Revision Counsel. 26 U.S. Code 102 – Gifts and Inheritances If a relative in another country sends you $200,000 as a gift, you owe zero federal income tax on it.
The word “gift” carries a specific meaning here. The transfer must come from genuine generosity, with no services performed, no repayment expected, and no other consideration attached. Calling a payment for consulting work a “gift” on the wire memo doesn’t make it one; the IRS will treat that as compensation. Large gifts also carry a separate reporting duty, discussed below.
Inheritances
Cash or property received as a bequest is also excluded from gross income.4Office of the Law Revision Counsel. 26 U.S. Code 102 – Gifts and Inheritances A distribution from a deceased person’s foreign estate is not taxable to you as income. Anything the inherited property generates after you receive it, such as rent or dividends, is taxable going forward.5eCFR. 26 CFR 1.102-1 – Gifts and Inheritances
Loans
A real loan is not income, because you owe the principal back. Borrowing $100,000 from a foreign lender and depositing it in your US account creates no tax liability. The arrangement has to be genuine, with actual repayment terms both parties can document. If the IRS concludes the loan was never meant to be repaid, it can reclassify the amount as taxable income.
Moving Your Own Money
Wiring your own savings from a foreign bank to a US bank is not a taxable event. You already own the money. A US citizen who transfers $500,000 of personal savings held abroad owes nothing on the transfer, assuming the underlying funds were either already taxed, or were never taxable to begin with (a prior gift, for instance).
The same is true for proceeds from selling a foreign asset. If you sold an overseas rental property for $1 million with a $600,000 basis, the $400,000 gain was taxable in the year of sale, whether the money sat abroad afterward or not. Wiring the proceeds to the US later does not tax them a second time. Keep records showing where the money came from and when any tax was paid, because a six-figure incoming wire will draw questions if the IRS asks about it.
Transfers That Are Taxable
Any transfer that represents earned income, business profits, or investment returns is fully taxable in the year you receive it or it becomes available to you. That includes:
- Wages, freelance fees, or commissions from a foreign employer, even for work done entirely outside the US.
- Profits from a business you operate overseas.
- Capital gains from selling foreign stocks, bonds, or real estate.
- Rent collected on property you own abroad.
- Interest and dividends on foreign bank accounts and foreign securities, taxable each year even if you leave the money in place.
All of this goes on your Form 1040 for the relevant year.2Internal Revenue Service. Reporting Foreign Income and Filing a Tax Return When Living Abroad Tools like the foreign earned income exclusion and the foreign tax credit can reduce or eliminate double taxation when the foreign country also taxed the income, but you have to file a return to use them; the income itself remains reportable.
Reporting Large Foreign Gifts and Inheritances
Foreign gifts and inheritances are not taxable, but the IRS wants to see the paperwork on the large ones. The reporting vehicle is Form 3520, and its purpose is informational.6Internal Revenue Service. About Form 3520, Annual Return To Report Transactions With Foreign Trusts and Receipt of Certain Foreign Gifts
You must file Form 3520 if, during the year, you received more than $100,000 in total gifts or bequests from a nonresident alien individual or a foreign estate. A separate, much lower threshold applies to gifts from foreign corporations or foreign partnerships; for the 2025 tax year that figure was $20,116, and it adjusts annually for inflation.7Internal Revenue Service. Rev. Proc. 2024-40 You aggregate all gifts from each category across the entire year to see whether you crossed the line.
The penalties are harsh, and they apply even though the underlying money isn’t taxable. Miss the deadline and the IRS can assess 5% of the unreported gift for each month you’re late, up to 25%.8Office of the Law Revision Counsel. 26 U.S. Code 6039F – Notice of Large Gifts Received From Foreign Persons On a $200,000 gift, that’s up to $50,000 for a form you forgot to file. Form 3520 is due when your income tax return is due, including extensions. Keep records identifying the donor, your relationship, and the nature of the transfer.
Reporting Foreign Financial Accounts
Holding money offshore, separate from any specific transfer, triggers two federal reporting obligations. They can apply at the same time; satisfying one does not satisfy the other.
FBAR (FinCEN Form 114)
If the combined value of all your foreign financial accounts exceeds $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts. This is a Treasury requirement administered by FinCEN, filed separately from your tax return through FinCEN’s electronic system.9Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) It covers bank accounts, brokerage accounts, mutual funds, and similar accounts held outside the US.
The threshold is based on the aggregate of all your foreign accounts. Three accounts holding $4,000 each put you over. The FBAR is due April 15 with an automatic extension to October 15, and no request is needed for the extension.9Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR)
FBAR penalties are among the steepest in the compliance system. A non-willful violation carries a penalty of up to $10,000 per violation, adjusted annually for inflation. A willful violation can bring a penalty equal to the greater of $100,000 (inflation-adjusted) or 50% of the account balance at the time of the violation.10Internal Revenue Service. 4.26.16 Report of Foreign Bank and Financial Accounts (FBAR) Courts have held that reckless disregard of the requirement can meet the willfulness standard, so “I didn’t know” is not a reliable defense when the information was available to you.
FATCA (Form 8938)
The Foreign Account Tax Compliance Act adds a second reporting layer through Form 8938, which you file with your annual tax return. It covers foreign financial accounts and certain non-account assets like foreign stock or bond holdings, interests in foreign entities, and foreign insurance or annuity contracts.11Internal Revenue Service. Summary of FATCA Reporting for U.S. Taxpayers
Thresholds depend on filing status and whether you live in the US or abroad:12Internal Revenue Service. Do I Need To File Form 8938, Statement of Specified Foreign Financial Assets
- Single, living in the US: total value over $50,000 on the last day of the year, or over $75,000 at any time during the year.
- Married filing jointly, living in the US: over $100,000 year-end, or over $150,000 at any time.
- Single, living abroad: over $200,000 year-end, or over $300,000 at any time.
- Married filing jointly, living abroad: over $400,000 year-end, or over $600,000 at any time.
Failing to file Form 8938 carries a $10,000 penalty. If you still haven’t filed within 90 days after the IRS sends you a notice, an additional $10,000 applies for each 30-day period of continued noncompliance, up to $50,000 in additional penalties.13eCFR. 26 CFR 1.6038D-8 – Penalties for Failure To Disclose Many people need to file both the FBAR and Form 8938; the two obligations run in parallel.
What Your Bank Reports Automatically
Even when you have no personal filing to do on a transfer, your US bank may report it. Under the Bank Secrecy Act, financial institutions must file a Currency Transaction Report for any transaction involving more than $10,000 in currency. Multiple smaller transactions on the same day are aggregated, and deliberately splitting a transfer into amounts below $10,000 to duck the report, known as structuring, is a federal crime.
Banks also file Suspicious Activity Reports on transactions of $5,000 or more that appear unusual, lack an obvious lawful purpose, or seem designed to evade reporting. You will not be notified when either report is filed. These filings do not mean you did anything wrong and they do not create a tax obligation, but they do create a record federal agencies can review. Two practical points follow: don’t structure transfers around the thresholds, and keep documentation showing the legitimate source of any large incoming funds.
A Note on Foreign Investments
If the money coming in is the proceeds of a foreign investment rather than a bank account balance, get advice before you transfer. Foreign mutual funds and certain foreign holding companies are treated as Passive Foreign Investment Companies, whose gains are taxed at the highest ordinary income rate for each year of the holding period with an interest charge added on top.14Internal Revenue Service. Instructions for Form 8621 Foreign trusts bring their own reporting through Forms 3520 and 3520-A, with penalties starting at $10,000 or 5% of trust assets for each year missed.15Internal Revenue Service. Instructions for Form 3520 These regimes can turn an ordinary-looking foreign investment into a substantially worse US tax outcome than the domestic equivalent.
