To deposit foreign currency at a U.S. bank, take the banknotes or foreign-drawn check to a teller at a large bank that handles international transactions, present government-issued photo ID and your account number, and let the bank convert the funds to dollars at its posted rate. Cash usually clears within a business day or two. A check drawn on a foreign bank can take six to eight weeks. Along the way you should expect an exchange-rate spread, a conversion fee, and — for checks — possible deductions taken out by the foreign bank before your account is credited.
Find a Bank That Actually Handles It
Not every branch can help. Large national banks are more likely to have the clearinghouse relationships and equipment to process non-dollar cash and checks. Smaller community banks and credit unions often lack those connections and will send you away. Even inside a big bank, only certain branches are set up as full-service international locations.
Call ahead or use the bank’s branch locator before you drive over. Ask two separate questions: does this branch take physical foreign banknotes, and does it accept checks drawn on foreign banks? Many branches handle one but not the other. If your bank cannot help at all, a dedicated currency exchange in a major city will usually beat an airport kiosk on rate, though neither option deposits the money into your account for you.
What to Bring to the Teller
You need unexpired government-issued photo identification. A driver’s license or a passport works. Banks verify identity under the Customer Identification Program required by the Bank Secrecy Act.1FFIEC BSA/AML InfoBase. Assessing Compliance with BSA Regulatory Requirements – Customer Identification Program Have your account number ready, and sort the bills by denomination to move the count along.
If the transaction involves more than $10,000 in currency, the bank must file a Currency Transaction Report with FinCEN. You don’t sign the report, but you will need to give the bank information such as your Social Security number so it can complete the filing.2FinCEN. Notice to Customers: A CTR Reference Guide The rule applies whether or not you already bank there. Breaking one deposit into smaller ones to stay under $10,000 is itself a federal crime, so don’t try it.
ATMs cannot recognize foreign bills. This has to be done in person.
The Exchange Rate You Actually Get
Banks do not give you the mid-market rate you see on Google. They apply a spread — the gap between their buy and sell prices — as a built-in margin, and most add a flat or percentage conversion fee on top. Common currencies like euros and Canadian dollars cost less to process than something thinly traded like Thai baht or South African rand.
Ask the teller to show you the rate and the fee before the transaction is booked. Once it is entered into the system, renegotiating is not practical. Keep the receipt; it is your proof of the exchange rate applied and the dollar amount credited, and you may need it at tax time.
Extra Deductions on Foreign Checks
For a foreign-drawn check, correspondent-bank charges add another layer. When your bank sends the check overseas for collection, the foreign bank that clears it can subtract its own fees before remitting the funds. Those deductions come out of the amount credited to you rather than as a separate charge on your statement, so the final deposit may be noticeably smaller than the face value suggests. The Federal Reserve confirms that foreign bank charges are assessed separately and pulled from the credit passed along to you.3Federal Reserve Bank Services. Foreign Check User Guide
How Long Until the Money Is Yours
The wait depends entirely on whether you deposited cash or a check, and the two timelines are not close.
Foreign Cash
Physical banknotes are the easy case. Once the teller books the conversion, the deposit is treated much like any in-person cash deposit. Federal rules require banks to make cash deposited in person available no later than the next business day.4eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) In practice, some banks add a day or two while the bills are verified at a central facility, but access within a few business days is typical.
Foreign Checks
Foreign-currency checks are different. Regulation CC — the rule that caps how long banks can hold ordinary check deposits — expressly excludes items payable in foreign currency from its definition of a “check.”4eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks (Regulation CC) That means there is no federally mandated release date. The hold lasts as long as collection takes.
Banks generally use one of two approaches. Some checks, especially those drawn on Canadian banks, can be handled as “cash letter” items and given provisional credit in roughly two business days. Most foreign checks are processed as collection items instead: the bank forwards the check to the foreign institution for clearance before crediting your account. That collection process usually runs six to eight weeks.5TFX: Treasury Financial Experience. Chapter 6000 Foreign And Currency Drawn On Foreign Banks
If a foreign check comes back unpaid, the bank reverses any provisional credit and may charge a returned-item fee. The CFPB has found those fees commonly land in the $10 to $19 range.6Bureau of Consumer Financial Protection. Bulletin 2022-06: Unfair Returned Deposited Item Fee Assessment Practices The reversal uses the exchange rate on the date of return, so you may be debited more or less than the original provisional credit depending on how the currency moved.3Federal Reserve Bank Services.

Currencies U.S. Banks Cannot Accept
The Office of Foreign Assets Control runs sanctions programs that restrict financial transactions with certain countries. Currencies from sanctioned nations, including Cuba, Iran, North Korea, and Russia, are effectively impossible to deposit at a U.S. bank because processing them would violate federal law.7Office of Foreign Assets Control. Sanctions Programs and Country Information Sanctions lists change often. If the currency comes from a country that has been in the news for geopolitical reasons, check OFAC’s current list before making the trip.
Separately, plenty of currencies are just non-convertible or too thinly traded for any U.S. bank to handle. A specialized foreign-exchange dealer may still buy them, though the rate will reflect the difficulty of moving that currency along.
The Tax Side People Miss
Converting foreign currency to dollars is, for tax purposes, a disposition of property. If the currency gained value against the dollar between the time you acquired it and the time you exchanged it, that gain can be taxable. Most people think of leftover foreign money as loose change, not an asset with a cost basis, and that is where the surprise comes from.
The $200 Personal-Use Break
For personal, non-business conversions, federal tax law provides a small allowance: if the gain from the rate movement is $200 or less, you owe nothing. Once the gain exceeds $200, the full amount is taxable as ordinary income.8Office of the Law Revision Counsel. 26 USC 988 – Treatment of Certain Foreign Currency Transactions The exception matters most on large conversions, such as an inheritance received in a foreign currency that appreciated before you brought it in. Losses on personal transactions are not deductible.
Large Gifts or Inheritances From Abroad
If the foreign currency came from a non-U.S. person as a gift or inheritance and the total value exceeds $100,000 during the year, you must report it to the IRS on Form 3520. Gifts from foreign corporations or partnerships trigger reporting at a lower, inflation-adjusted threshold, which was $19,570 for 2024.9Internal Revenue Service. Gifts from Foreign Person The gift itself is not taxed, but the penalty for failing to report can reach 25 percent of its value.10Internal Revenue Service. Instructions for Form 3520
FBAR Is a Different Situation
One boundary worth stating clearly: FBAR reporting applies to accounts held at banks outside the United States, not to a U.S. account that happens to receive foreign currency. If you have foreign accounts and their combined balances top $10,000 at any point in the year, you file FinCEN Form 114 by April 15, with an automatic extension to October 15.11Financial Crimes Enforcement Network. Report Foreign Bank and Financial Accounts12Financial Crimes Enforcement Network. Due Date for FBARs The filing goes to FinCEN, not the IRS, and it is separate from your tax return.
Is the Deposit FDIC-Insured?
Yes. At an FDIC-insured bank, deposits denominated in foreign currency are covered the same as dollar deposits, up to $250,000 per depositor per bank.13FDIC. Understanding Deposit Insurance If the bank failed, the FDIC would convert a foreign-currency deposit to dollars using the Federal Reserve Bank of New York’s noon buying rate on the date of default, unless the deposit agreement sets a different rate.14eCFR. 12 CFR 330.3 – General Principles Coverage does not depend on citizenship or residency, so foreign nationals holding accounts at U.S. banks are protected as well.
