How to Deposit Foreign Currency Into a Bank Account: Fees and Holds

To deposit foreign currency into a bank account, take the banknotes to a branch of a bank that handles that currency and where you already hold a checking or savings account, present a government-issued photo ID, and let the teller convert the bills at the bank’s rate and credit the dollar amount to your account. The deposit usually posts within one to three business days. What you actually pocket depends on the exchange-rate spread, any flat fee, the condition of your bills, and whether the currency is common enough for the branch to handle on the spot.

Which Banks Handle Foreign Cash

Not every bank offers this service, and among those that do, not every branch is equipped for it. Large national banks are the most reliable option, but call ahead or use the bank’s branch locator to confirm the specific location handles the currency you’re holding. Some branches lack the software, cash drawers, or trained tellers to process non-dollar banknotes.

You almost always need an existing account at the bank. U.S. Bank, for example, requires a checking, savings, or money market account before it will exchange foreign currency, and it sets a $20 minimum in U.S.-dollar equivalent for the transaction.¹ Walking into a random branch without an account and expecting to convert a handful of euros usually won’t work. If no bank you belong to offers the service, a currency counter at an international airport or a standalone foreign-exchange service can convert the cash, though the markup tends to be steeper.

Banks are also selective about which currencies they’ll accept. Major ones such as the British pound, euro, Canadian dollar, Japanese yen, and Swiss franc are widely handled. Currencies from smaller economies may not be accepted at all, or the bank may need to ship the bills to a central processing facility before crediting your account, which stretches the timeline by several days.

What to Bring to the Branch

The requirements are simple, but forgetting any one of them means a wasted trip:

A government-issued photo ID, such as a driver’s license or passport. The bank has to verify your identity for any cash transaction.
Your account number, or a debit card that carries it. The teller deposits the converted funds directly.
The foreign banknotes themselves. Most banks accept paper bills only; foreign coins are generally not taken.¹

Some branches ask you to fill out a foreign-currency deposit slip listing the currency, the amount in that denomination, and the account holder’s name. Others handle everything electronically at the window. Either way, sorting your bills by denomination before you get in line speeds things up.

What It Costs

Banks make money on foreign currency exchange in two ways, and sometimes both at once. The first is the exchange-rate spread: the rate you’re quoted is less favorable than the mid-market rate you’d see on a financial news site or currency converter, and the gap is the bank’s margin. The second is an explicit transaction fee.

U.S. Bank charges a $10 exchange fee on transactions worth $300 or less, waived on larger amounts.² Bank of America uses a spread-only model, earning its compensation from the difference between what it pays for the currency and what it charges customers.³ Structures vary, so ask the teller for the exact rate and any flat or percentage-based charge before you hand over your bills. Rates update throughout the business day, and the number quoted at the window is typically locked in for that transaction.

If you’re exchanging a large amount, even a small difference in the spread matters. Compare the bank’s rate against the current mid-market rate on a free converter before you commit. A 2–3% markup on $500 is $10–$15; on $5,000 it’s $100–$150.

What Happens at the Teller Window

With ID, account details, and sorted bills in hand, the process moves quickly. The teller counts your banknotes and runs them through a counting machine with ultraviolet sensors and magnetic-ink detectors to verify authenticity. Older or less common bills may get a manual look for security threads, watermarks, and other features specific to that currency.

Once the bills clear, the teller applies the bank’s current internal rate to calculate the dollar value, subtracts any fee, and shows you the net amount before finalizing. If the rate or the total looks off, this is your moment to ask questions or decline. After you confirm, the teller processes the deposit and hands you a printed receipt showing the original foreign amount, the exchange rate, the fees, and the dollar amount credited. Keep the receipt until you see the deposit posted in online banking. It’s your only proof of the terms if something looks wrong later.

When the Money Becomes Available

Don’t expect instant access. Physical foreign-currency deposits generally take one to three business days to clear, depending on when you deposited and how common the currency is. During that window, the bank accounts for the cash in its vault and completes the conversion through its treasury operations. Online banking will show the deposit as pending until it posts.

Once posted, your statement reflects a dollar-denominated credit, and most banks include a note showing the exchange rate that was applied, which is useful for tax records. If something goes wrong in processing, such as a bill that fails authentication, the bank sends a notice by mail or secure message explaining the adjustment.

What Banks Won’t Accept

Beyond the coin restriction, several situations will get your deposit turned away.

Currency from sanctioned countries. Federal law prohibits U.S. financial institutions from processing transactions tied to certain sanctioned nations, and the Treasury’s Office of Foreign Assets Control maintains the active list, which has included North Korea, Iran, Cuba, and Russia among others. Banks will not accept currency from these countries regardless of amount.⁴
Damaged or mutilated bills. A banknote that’s torn, heavily soiled, or missing a significant portion may be rejected. The Bureau of Engraving and Printing redeems mutilated U.S. bills at face value when clearly more than half remains along with key security features, but no equivalent federal program exists for foreign notes; you’d need to contact the issuing country’s central bank or a specialized exchange service.⁵
Obsolete or demonetized bills. Countries occasionally retire old designs. If the issuing country no longer honors a series, your U.S. bank won’t either.
Foreign coins, at most banks.¹

Bills that are merely dirty or limp rather than truly mutilated can often still be exchanged. Tellers have some discretion, so it’s worth bringing questionable notes in and letting them take a look.

If You Have a Foreign-Currency Check Instead of Cash

A check drawn on a foreign bank or denominated in a foreign currency is handled differently, and the process is slower and more expensive. You must visit a branch in person; mobile deposit apps at major banks do not accept these items.⁶ U.S. Bank likewise requires an in-person visit for foreign checks.⁷

Foreign checks often go through a collection process where the bank sends the check to the foreign institution for payment, which can take several weeks. At U.S. Bank, a Canadian check costs $6 to deposit, checks from select other countries run $12, and a full collection basis adds a $55 courier fee and a $55 initiation fee per check, plus $35 if the check is returned unpaid.⁸ The foreign bank may also deduct its own fees from the proceeds. For large amounts, a wire transfer from the sender’s foreign account directly to your U.S. account is usually faster and cheaper than mailing a paper check. Canadian checks processed through clearing channels may see provisional credit in about two business days, while checks from other countries sent through collection can take two to six weeks to appear.

Tax on Any Gain From the Conversion

If the dollar weakened between the time you acquired the foreign cash and the time you convert it back, you’ve technically made a profit, and the IRS may want a share. Under Section 988 of the tax code, gains from personal foreign-currency transactions are tax-free as long as the gain stays at or below $200. Once the gain exceeds $200, the entire amount becomes taxable as ordinary income.⁹

The math: suppose you received £5,000 as a gift when the rate was $1.20 per pound, giving you a cost basis of $6,000. You deposit those pounds a year later at $1.30, netting $6,500. Your $500 gain exceeds the $200 threshold, so the full $500 is ordinary income.

Losses are asymmetric. Section 988 excludes personal transactions from its general loss-recognition rules, so you cannot deduct a loss from exchanging leftover vacation money at an unfavorable rate.⁹ Most casual travelers converting a few hundred dollars in leftover currency will never cross the $200 gain threshold.

Deposits Over $10,000

Any deposit of foreign currency worth more than $10,000 in U.S.-dollar equivalent triggers a Currency Transaction Report (FinCEN Form 112), which the bank files with the Financial Crimes Enforcement Network.¹⁰ The same rule applies to multiple deposits in the same business day that the bank knows are related and that together cross $10,000. The bank handles the filing; you just need accurate ID and honest answers about the source of the funds. The teller may ask whether the money came from an inheritance, business income, a trip abroad, or something else to complete the form. The bank must file within 15 calendar days.

Do not break a large deposit into smaller amounts to stay under the line. That’s structuring, and it’s a federal crime even if the underlying money is entirely legitimate. The penalty is a fine and up to five years in prison, or up to ten years if the structuring is part of a broader pattern of illegal activity exceeding $100,000 in a 12-month period.¹¹ Banks train staff to spot the pattern, and the consequences of getting caught far outweigh the minor inconvenience of a CTR filing.

If You Brought the Cash Across the Border

The deposit paperwork is separate from the paperwork you owe at the border. Anyone who physically carries, mails, or ships currency or monetary instruments worth more than $10,000 into or out of the United States must file FinCEN Form 105 with U.S. Customs at the port of entry or departure.¹² Failure to declare can result in seizure of the funds and criminal penalties. The bank’s CTR filing on your deposit and your border declaration are separate obligations, and one does not substitute for the other.
