No, it is not illegal to have an offshore bank account. Any U.S. citizen or resident can legally hold a bank account in another country. What breaks the law is hiding that account, or the income it earns, from the federal government. The IRS and the Treasury Department require you to disclose foreign accounts and pay tax on whatever they earn, and the penalties for skipping either duty are some of the steepest in the tax code.
When a Foreign Account Is Perfectly Legal
People open foreign bank accounts for ordinary reasons. Expats and remote workers living abroad need local accounts to receive paychecks, pay rent, and dodge constant currency-conversion fees. Business owners paying overseas contractors or suppliers find it cheaper to move money through a local account than to wire funds internationally every time an invoice comes due.
Foreign accounts also give you access to currencies, investment products, and real estate markets that domestic banks don’t offer. Some account holders use foreign jurisdictions for asset protection, legally placing funds outside the reach of potential domestic lawsuits. None of that is illegal as long as you report the account and pay the tax you owe.
When a Foreign Account Becomes Illegal
An offshore account turns illegal the moment you use it to hide something from the government or the courts. The most common violation is tax evasion: deliberately leaving foreign income off your return so you don’t pay tax on it. The IRS draws a hard line between a careless mistake and a willful attempt to defraud, and intent drives the size of the penalty.
Money laundering is another common charge. It involves routing proceeds from criminal activity through foreign accounts to disguise where the money came from. Federal prosecutors regularly pursue offshore laundering cases tied to fraud, drug trafficking, and corruption.
Using offshore accounts to hide assets from creditors, conceal property during bankruptcy, or defy a court order in a divorce also crosses into illegality. Legitimate asset protection is one thing. Moving money overseas after a lawsuit has been filed or after a court has frozen your assets is fraud.
What You Have to Report
Two separate filings apply to foreign accounts, and they go to different agencies with different thresholds. You may owe one, both, or neither, depending on how much you hold overseas.
FBAR (FinCEN Form 114)
The Report of Foreign Bank and Financial Accounts requires you to disclose every foreign financial account you own or control if the combined value of all those accounts tops $10,000 at any point during the year. That is an aggregate number. Three accounts holding $4,000 each push you over the line, and all three must be reported. The FBAR covers bank accounts, brokerage accounts, and mutual funds held at foreign institutions, and it applies whether or not the accounts generated any taxable income.1Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR)
Accounts held inside an IRA you own, or a retirement plan you participate in, are exempt.1Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR)
The FBAR is filed electronically through FinCEN’s BSA E-Filing System, not with your tax return.2Financial Crimes Enforcement Network. How Do I File the FBAR? The deadline is April 15, with an automatic extension to October 15 that requires no separate request.3Financial Crimes Enforcement Network. Due Date for FBARs
Form 8938 (FATCA)
Form 8938 is a second reporting layer, created by the Foreign Account Tax Compliance Act. It attaches to your annual income tax return and goes to the IRS. Its thresholds are higher than the FBAR’s and depend on your filing status and where you live.4Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets
For taxpayers living in the United States, a single filer must file if total foreign assets exceed $50,000 on the last day of the tax year or $75,000 at any point during the year. For married couples filing jointly, the thresholds are $100,000 and $150,000. The thresholds are considerably higher for taxpayers living abroad.4Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets
Form 8938 covers a broader range of assets than the FBAR, including foreign stocks, partnership interests, and financial instruments issued by foreign entities. Filing one form does not excuse you from the other, and many people with significant foreign holdings must file both.5Internal Revenue Service. Instructions for Form 8938
Taxes on Money Inside a Foreign Account
The United States taxes citizens and residents on worldwide income, no matter where the money sits. Interest, dividends, capital gains, and any other profits earned in a foreign account are subject to U.S. income tax and must be reported on your return. Interest and dividends go on Schedule B of Form 1040, and Part III of that schedule specifically asks whether you hold any foreign financial accounts.6Internal Revenue Service. About Schedule B (Form 1040), Interest and Ordinary Dividends
Reporting the account and paying tax on its income are two independent duties. Properly disclosing every account on your FBAR and Form 8938 does not protect you from prosecution if you leave the income off your tax return. Paying tax on the interest does not relieve you of the duty to file the FBAR.
If a foreign country taxes the same income the U.S. taxes, you don’t necessarily pay twice. The foreign tax credit offsets your U.S. tax bill by the amount you already paid to another country on the same income, and you claim it on Form 1116. One catch: if you use the foreign earned income exclusion to shield wages earned abroad, you cannot also claim the foreign tax credit on that excluded income.7Internal Revenue Service. Foreign Tax Credit
Penalties If You Don’t Report
The penalty structure distinguishes sharply between honest mistakes and deliberate concealment. Even the honest-mistake tier is expensive enough to get your attention.
A non-willful failure to file an FBAR carries a penalty of up to $16,536 per violation. If the IRS finds the failure was willful, the penalty jumps to the greater of $165,353 or 50% of the highest balance in the unreported account, for each year of the violation.8Federal Register. Inflation Adjustment of Civil Monetary Penalties Both figures are adjusted annually for inflation. The IRS has six years from an FBAR’s due date to assess these penalties, so willful non-filers can face cumulative amounts that dwarf the account balance itself.9Internal Revenue Service. Extending the FBAR Penalty Assessment Period
Missing Form 8938 triggers an initial $10,000 penalty. If you still haven’t filed 90 days after the IRS sends a notice, an additional $10,000 penalty accrues for every 30-day period the failure continues, up to $50,000 in additional penalties.10Office of the Law Revision Counsel. 26 USC 6038D – Information With Respect to Foreign Financial Assets
Willful FBAR violations can also be prosecuted criminally: a fine of up to $250,000 and up to five years in prison. If the violation is part of a broader pattern of illegal activity involving more than $100,000 in a 12-month period, those maximums double to $500,000 and ten years.11Office of the Law Revision Counsel. 31 US Code 5322 – Criminal Penalties Tax evasion under the Internal Revenue Code separately carries a fine of up to $100,000 and up to five years in prison.12Office of the Law Revision Counsel. 26 USC 7201 – Attempt to Evade or Defeat Tax Prosecutors can stack the charges, so a single unreported offshore account could expose you to both sets of penalties at once.
Fixing Missed Filings
If you’ve fallen behind on FBAR or FATCA reporting, the IRS offers a couple of paths back into compliance. Which one fits depends on whether you also owe back tax and whether your failure was willful.
If you properly reported all your foreign income and paid the tax, but missed the FBARs, you can submit the late forms through FinCEN’s BSA E-Filing System with a statement explaining the delay. As long as the IRS hasn’t already contacted you about an examination or requested delinquent returns, no penalty is imposed for the late filings.13Internal Revenue Service. Delinquent FBAR Submission Procedures
If you owe back tax on unreported foreign income, the streamlined filing compliance procedures let you file amended returns and late FBARs with reduced penalties, provided you certify that the failure was non-willful, meaning it came from negligence, inadvertence, or a good-faith misunderstanding of the law. You are ineligible if the IRS has already opened a civil examination or criminal investigation.14Internal Revenue Service. Streamlined Filing Compliance Procedures
Taxpayers living in the United States pay a one-time penalty equal to 5% of the highest aggregate balance of their unreported foreign financial assets during the covered period.15Internal Revenue Service. U.S. Taxpayers Residing in the United States Taxpayers living abroad who meet additional residency requirements face no miscellaneous offshore penalty at all. Compared with the standard willful penalties, either version is a steep discount, which is why the IRS created the program: to coax non-filers out of the shadows.
Why Opening One Can Still Be Difficult
Even though offshore accounts are legal, actually getting one can be frustrating. FATCA requires foreign financial institutions to report account information on their U.S. clients directly to the IRS. The compliance cost of that reporting has made many foreign banks reluctant to take on American customers, and some institutions outright refuse to open accounts for U.S. citizens or green card holders because the paperwork isn’t worth the business.16Internal Revenue Service. Summary of FATCA Reporting for U.S. Taxpayers
Banks that do accept U.S. clients typically require extensive documentation: a valid passport, proof of local address, a Social Security number or taxpayer identification number, and sometimes a reference from your existing bank. The process takes longer and involves more paperwork than opening a domestic account. If you’re an expat, starting in person at a branch in the country where you live or work tends to go more smoothly than applying remotely.
