Yes, you can add a foreigner to your bank account at a U.S. bank, including someone who lives outside the country. No federal law prohibits it, and banks handle these requests regularly for international families, cross-border couples, and business partners. The paperwork is heavier than for a domestic co-holder because the bank has to verify a non-U.S. person’s identity and run sanctions and anti-money-laundering checks, so gathering the right documents before you walk in saves weeks.
Joint Owner or Authorized Signer
This is the choice that matters most, and people get it wrong often enough that it belongs at the top.
A joint owner has equal legal rights to the account. Either owner can deposit, withdraw, or close it without the other’s permission. Most joint accounts carry a right of survivorship, which means that if one owner dies, the survivor automatically receives the balance outside of probate.1Consumer Financial Protection Bureau. What Happens if I Have a Joint Bank Account With Someone Who Died? That is useful for estate planning, but it also hands the other person full access to your money today.
An authorized signer can transact on your behalf but has no ownership claim. They can deposit checks, pay bills, and withdraw cash. They cannot close the account or inherit the balance. If the signer gets sued or chased by debt collectors, those creditors generally cannot reach your account because the signer owns none of it. For most arrangements where you just need someone to handle banking while you travel or live abroad, authorized signer is the safer status.
Documents the Foreign Person Needs
When you add someone to an existing account, the bank treats that person as a new customer for identity verification. Federal regulators have confirmed that a co-owner added to an existing deposit account is a “customer” under the Customer Identification Program rules that apply when opening a new account.2FinCEN. FAQs: Final CIP Rule Those rules require the bank to collect and verify identifying information for every new customer.3eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks
For a foreign national, the main document is an unexpired passport. It carries a photo, legal name, date of birth, and nationality verified by a sovereign government. If a passport is unavailable, or the bank asks for a second piece of ID, acceptable alternatives include a foreign driver’s license, a government-issued photo ID card, an alien identification card, or a consular identification card.4HelpWithMyBank.gov. What Type(s) of ID Do I Need to Open a Bank Account? Documents in another language usually need a certified English translation.
Most foreign nationals do not have a Social Security Number, and the rules don’t require one. Federal regulations let the bank accept a passport number and country of issuance, a taxpayer identification number, an alien identification card number, or the number from any other government-issued document showing nationality or residence that includes a photograph.4HelpWithMyBank.gov.

Tax Paperwork: ITIN and Form W-8BEN
If the account earns interest or dividends, tax reporting kicks in. Two documents matter.
Individual Taxpayer Identification Number
A foreign national who is not eligible for a Social Security Number but has U.S. tax reporting obligations uses an IRS Individual Taxpayer Identification Number (ITIN).5eCFR. 26 CFR 301.6109-1 – Identifying Numbers Many major banks accept an ITIN in place of an SSN when adding someone at a branch. The foreign person applies with IRS Form W-7, which requires supporting documentation like a passport. If the account earns no interest, some institutions may not require a tax ID at all, but this varies.
Form W-8BEN and the 30% Withholding Rate
A nonresident alien added to an interest-bearing U.S. account should submit IRS Form W-8BEN. The form certifies foreign status and lets the person claim a reduced withholding rate under an applicable tax treaty.6Internal Revenue Service. About Form W-8 BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals) Without a W-8BEN on file, U.S. law requires the bank to withhold 30% of any U.S.-source interest paid to a nonresident alien.7Office of the Law Revision Counsel. 26 USC 1441 – Withholding of Tax on Nonresident Aliens If the person’s home country has an income tax treaty with the United States, the form can reduce that rate sharply or wipe it out.
Completing it is straightforward. The person provides their full legal name, permanent residence address in their home country, and foreign tax identification number on Part I. To claim treaty benefits, they identify their country of tax residence on Line 9.8Internal Revenue Service. Instructions for Form W-8BEN The completed form goes to the bank, not the IRS. One detail people miss: the W-8BEN expires at the end of the third calendar year after signing. A form signed in 2026 is valid through December 31, 2029, and a new one has to be filed before it lapses.
Countries the Bank Will Refuse
The Office of Foreign Assets Control (OFAC) at the U.S. Treasury Department maintains a list of sanctioned countries and individuals. If the person you want to add is a national of or ordinarily resides in a comprehensively sanctioned country, the bank will almost certainly say no. As of early 2026, the comprehensively sanctioned countries are Cuba, Iran, North Korea, and Russia, along with the Crimea, Donetsk, and Luhansk regions of Ukraine.9U.S. Department of the Treasury. Sanctions Programs and Country Information Transactions involving persons ordinarily resident in those countries generally require a specific OFAC license, which banks almost never pursue for personal accounts.
A longer list of countries is subject to more targeted sanctions. Afghanistan, Belarus, Myanmar, and Venezuela are examples. Whether a national of one of these can be added depends on the specific program and the bank’s own risk appetite. Expect a longer compliance review, and be ready for the bank to decline on internal policy even when OFAC does not outright prohibit the relationship.
How the Process Actually Works
Procedures vary by bank, but the pattern is consistent. Most banks require the foreign person to visit a U.S. branch in person because their online systems are not built to onboard customers without a Social Security Number. If an in-person visit is impossible, some larger institutions offer digital signature platforms or allow documents to be signed at a partner institution or U.S. consulate abroad, often before a notary.
What to expect once you are ready:
- Gather documents in advance. The foreign person needs their unexpired passport, a second government-issued ID, proof of their home-country address such as a utility bill or lease, their ITIN or foreign tax identification number, and a completed Form W-8BEN if the account earns interest.
- Visit the branch together. The primary account holder and the foreign person normally need to appear in person. Bring originals plus certified English translations for anything not in English.
- Sign a new signature card. This document binds the new person to the bank’s terms, grants transaction authority, and specifies whether they are a joint owner or an authorized signer.
- Wait for compliance review. The bank cross-checks the new person against international watchlists and its own risk parameters. Five to ten business days is typical; longer for nationals of countries under targeted sanctions.
- Receive confirmation. Once approved, the primary holder gets notification by mail or secure message and the new person has access.
Some banks charge an administrative fee for international additions; some do not. Call ahead about fees, documents, and whether you need an appointment. Showing up unannounced is the quickest way to waste a trip.
Risks Before You Add a Joint Owner
Joint ownership gives the other person real legal power over your money, and the exposure runs beyond the obvious risk that they could drain the account.
Creditor Access
If a joint owner has debts or faces a lawsuit, their creditors may be able to garnish the account. The law generally presumes each joint owner has equal rights to the funds, so a creditor pursuing your co-owner does not have to prove which dollars came from whom. In some states, creditors can seize up to half the account; in others, the entire balance. You can fight it by tracing the funds to your own deposits, but that takes detailed records and is easier said than done.
Survivorship Can Override Your Will
Most joint accounts carry a right of survivorship, so the surviving owner inherits the balance automatically.1Consumer Financial Protection Bureau. What Happens if I Have a Joint Bank Account With Someone Who Died? If you intended the money to go to your children but the joint owner outlives you, the joint owner gets it regardless of what your will says. With a foreign co-owner, this can also pull the funds into cross-border estate and tax questions in their home country.
Gift Tax
Adding someone’s name does not usually trigger gift tax by itself. A taxable gift generally occurs when the non-contributing co-owner withdraws funds they did not deposit. If you put $50,000 into the account and the foreign co-owner withdraws $30,000 for their own use, the IRS may treat that $30,000 as a gift from you.
For 2026, the annual gift tax exclusion is $19,000 per recipient.10Internal Revenue Service. What’s New – Estate and Gift Tax Co-owner withdrawals above that amount in a single year could require you to file Form 709, though no tax is owed until you exceed the lifetime exemption. If the foreign co-owner is your spouse but not a U.S. citizen, a separate annual exclusion of $194,000 applies for 2026.11Internal Revenue Service.
