What you need to know before you start

Opening an international bank account is possible, but the process depends entirely on where you are, where the bank is, and what you plan to use the account for. There is no single "international account" — you are either opening a domestic account in a country where you do not live, or opening an account with a bank that serves customers across borders. The requirements, costs, and timeline differ sharply between these two paths.

Most people who need cross-border banking fall into one of three situations: you live outside your home country and need an account there; you live in one country and want an account in another for business or investment; or you need to move money regularly between countries. Each situation has different solutions, and some routes are closed to you depending on your citizenship, residency status, and the countries involved.

Key Takeaways

  • Opening a bank account in a country where you do not live usually requires residency proof, a local address, and often a local tax identification number — requirements vary by country and by bank.
  • Banks that serve international customers without requiring residency (sometimes called "international banks" or "offshore banks") exist but charge higher fees and have stricter identity verification than domestic accounts.
  • US citizens face additional barriers because US tax law requires banks worldwide to report US account holders to the Internal Revenue Service, which makes many banks unwilling to serve them.
  • The fastest route for regular international transfers is often a fintech money transfer service or a multi-currency account rather than a traditional bank account in another country.
  • You will need to prove your identity with a passport, provide a residential address, and usually show proof of income or funds — the exact documents depend on the country and the bank's internal rules.

Opening an account in your country of residence

If you have moved to a new country and want a local bank account there, the process is closest to opening an account in your home country — but with extra steps. You will need to visit a branch in person or complete an online process, depending on the bank. Most banks require a residential address in that country, which means you need proof of residence: a utility bill, a lease, a government-issued ID with a local address, or a letter from your employer or landlord.

You will also need a tax identification number or national ID number for that country. In many places, you cannot get one without proof of residency or a work permit. The order matters: some countries require you to register with tax authorities before opening a bank account, while others let you open the account first and register later. Call the bank directly to ask what order they require, because their website often does not say.

The documents you bring depend on the country. The United Kingdom requires a passport and proof of address. Germany requires a passport, proof of address, and a tax identification number (Steueridentifikationsnummer). Canada requires a government-issued ID and proof of address. Australia requires a passport, proof of address, and a tax file number. Some countries also ask for proof of income, employment, or funds on deposit — this varies by bank and by how much you plan to keep in the account.

The timeline is usually two to four weeks from process to account opening, though some banks are faster. Online applications can sometimes be completed in days if you can upload documents directly, but many banks still require a branch visit or a video call with an employee to verify your identity in person.

Opening an account as a non-resident

If you want an account in a country where you do not live and do not have residency, your options narrow. Some banks will open accounts for non-residents, but they are usually banks in financial centres (Singapore, Hong Kong, Switzerland, the United Arab Emirates, Mauritius) and they charge higher fees, require larger minimum deposits, and have stricter rules about who they will serve.

These banks typically require a passport, proof of address in your home country, proof of income or net worth, and often a letter of reference from another bank or financial institution. Some require you to visit a branch in person; others will work with you remotely if you use a video call for identity verification. Minimum deposits often start at $10,000 or higher, and annual fees can be several hundred dollars.

The reason for these barriers is regulatory: banks face heavy penalties if they serve customers they cannot properly identify or whose source of funds they cannot verify. A non-resident account is riskier for the bank because they cannot easily verify your address or income, so they charge more and ask for more documentation to offset that risk.

Some countries have specific programs for non-residents. Portugal, for example, allows non-residents to open accounts for the purpose of buying property. The United Arab Emirates allows non-residents to open accounts if they have a local address or a local sponsor. Ask the bank directly whether they have a non-resident program, because this information is rarely advertised on their website.

US citizens and the FATCA barrier

If you are a US citizen, you face an additional layer of complexity. The Foreign Account Tax Compliance Act (FATCA) requires banks worldwide to report accounts held by US citizens to the Internal Revenue Service. This reporting requirement makes many banks unwilling to serve US customers, especially if the account is small or the customer lives far away.

Some banks have straightforward stopped serving US citizens entirely because the compliance cost is too high. Others will serve you but charge higher fees to cover the cost of FATCA reporting. A few banks specialize in serving US expats and have built their compliance systems around FATCA reporting, but they are fewer in number and often charge premium fees.

If you are a US citizen opening an account abroad, expect to provide your Social Security Number, sign FATCA consent forms, and potentially wait longer for approval because the bank needs to set up special reporting procedures for your account. Some banks will ask you to sign a W-8BEN form (if you are not a US resident) or a W-9 form (if you are), which certifies your tax status to the bank.

Alternatives to a traditional bank account

For many people, opening a traditional bank account in another country is slower and more expensive than the alternatives. If you need to move money between countries regularly, a fintech money transfer service (Wise, OFX, Remitly, or similar) often works faster and cheaper than a bank account. These services let you hold balances in multiple currencies and transfer between them at real exchange rates, without the fees of a traditional bank.

If you need a local account number to receive payments in a specific country, some fintech services provide local account numbers without requiring you to open a full bank account. Wise, for example, gives you a local UK bank account number and sort code if you hold GBP with them, even if you live outside the UK. This works for receiving payments but not for all banking services (you cannot get a debit card, for example).

Multi-currency accounts offered by some banks (HSBC, Citibank, Standard Chartered) let you hold and transfer money in multiple currencies from a single account, which can reduce the number of accounts you need. These accounts are easier to open if you already have a relationship with the bank in your home country.

Documents you will typically need

The exact documents vary by country and by bank, but most will ask for some combination of the following. A valid passport is almost always required. Proof of residential address — a utility bill, lease, or government letter — is required in most countries. Proof of income or employment (a pay stub, employment letter, or tax return) is common but not universal. Proof of funds or a bank statement showing your balance may be required if you are opening an account with a large minimum deposit.

Some banks also ask for a reference letter from another bank or financial institution, especially if you are a non-resident or if you are opening an account with a large balance. A few banks ask for proof of the source of your funds (where the money came from), particularly if you are depositing a large sum at once. This is part of anti-money-laundering compliance and is more common at banks serving non-residents.

You may also need to provide information about the purpose of the account (personal use, business, investment) and your employment or business details. Some countries require a tax identification number before you can open an account; others issue one after you open the account. Ask the bank what documents they need before you gather them, because requirements differ between branches and between account types.

Timeline and costs

The timeline from process to account opening ranges from a few days (for some online fintech accounts) to four to eight weeks (for traditional banks in countries with strict regulatory requirements). Residency-based accounts are usually faster than non-resident accounts because the bank can verify your address more easily. Online applications are usually faster than in-person visits, but many banks still require at least one video call or branch visit for identity verification.

Costs vary widely. Opening a domestic account in your country of residence is usually free or costs a small one-time fee (under $50). Opening a non-resident account at a bank in a financial centre can cost $100 to $500 in setup fees, plus annual maintenance fees of $200 to $1,000 or more. Multi-currency accounts at major banks usually have no setup fee but charge monthly maintenance fees ($10 to $50) and higher exchange rate markups than fintech services.

Fintech money transfer services usually have no account opening fee and charge only when you transfer money — typically 1 to 3 percent of the amount transferred, depending on the currency pair and the service. This is often cheaper than a bank account if you transfer money infrequently, but more expensive if you transfer large amounts regularly.

Frequently Asked Questions

Can I open a bank account in another country online without visiting in person?

Some banks allow fully online applications with video identity verification, but many still require at least one in-person visit to a branch or a video call with an employee. Fintech services and some digital banks allow fully remote account opening. Ask the bank whether they accept remote applications before you start the process.

What happens if I cannot get a local tax ID number before opening an account?

Some banks will open an account first and let you register for a tax ID later; others require the tax ID before you explore. A few banks will help you register for a tax ID as part of the account opening process. Call the bank and ask what order they require, because this varies by institution and by country.

Do I need to close my bank account in my home country to open one abroad?

No. You can hold accounts in multiple countries at the same time. However, if you are a US citizen, you must report all foreign accounts over $10,000 to the IRS on your tax return, regardless of whether you are a resident or citizen of the other country.

Is it cheaper to use a money transfer service or open a bank account?

For occasional transfers, a money transfer service is usually cheaper because there is no monthly fee. For regular large transfers or if you need a local account number to receive payments, a bank account may be cheaper over time. Compare the costs for your specific transfer pattern before deciding.

What if a bank refuses to open an account for me because I am a US citizen?

Some banks have stopped serving US citizens due to FATCA compliance costs. If a bank refuses, try banks that specialize in serving expats, or use a fintech money transfer service instead. You can also ask whether the bank will serve you if you use a video call for identity verification, as some banks are more willing to serve US citizens remotely than in person.
