What is offshore banking?

The simple definition of offshore banking is that it is banking done outside your home country. The term encompasses companies and individuals who invest and do business with international banks.

Over the past 50 years, Switzerland and the British territories of Bermuda and the Cayman Islands became renowned hubs for offshore banking. But in recent years, Ireland, Belize, and the African nation Mauritius have also come into the spotlight.

As stated, many people have a perception that offshore banking is only for the rich, accountants, or wealthy criminals. But while those groups may use them, offshore banking itself is not an illegal activity if you don’t use one as such—like for tax evasion or money laundering.

For example, it’s legal to put your money in countries that have different banking systems—if you follow the rules and regulations of the foreign and United States governments.

Why have an offshore bank account?

People use offshore banks for a variety of legitimate reasons like doing business or having investments outside of their home country or just having an account somewhere they spend a lot of time.

Offshore accounts make things easier for you to honor financial obligations in a foreign country—sometimes multiple. They’re a useful asset for people who take and make international payments regularly and for those who make a lot of international transfers.

Most expats living abroad use bank accounts in both their home country and in the country where they live. You could consider opening an account in another country if you want an efficient way to manage money abroad and possibly save and invest as well.

Here’s a rundown of some common reasons you would have an offshore account:

  • You live and/or work abroad already
  • You have plans to work or retire abroad
  • You do business or your company regularly assigns you to work in multiple countries
  • You regularly travel between countries for work, vacation, or to visit family
  • You’re a freelancer or businessperson who is paid in a foreign currency
If any of those reasons apply to you, Wise could be a great asset for your finances. With a free Wise account, you can get bank details in 10 currencies, which will allow you to pay and get paid just like a local. Plus, you can convert and hold balances in over 50 currencies.

Can a U.S. Citizen open an offshore bank account?

Yes. There’s no law that prevents US citizens from opening an offshore bank account.

However, if you intend to open an offshore account, it’s important to be aware of the tax implications associated with the account—both reporting and possible payments.

The US government passed the Foreign Account Tax Compliance Act—FATCA—in 2010 as a response to the 2008 financial crisis.

And while the law was created as a means for more transparency with global businesses, it also requires that US citizens—whether you’re at home or abroad—report foreign holdings on their annual tax returns if they meet certain requirements.

Also, if you have more than $10,000 in offshore accounts, you must submit a Financial Crimes Enforcement Network—FinCEN—form 114, Report of Foreign Bank and Financial Accounts—FBAR—with your tax returns.¹

Note that this is a combined total on all offshore accounts.

If you’re thinking about opening an offshore bank account, be aware of the IRS rules and regulations. You may need to file both the FinCEN form 114, FBAR and the FATCA form if you qualify.

Fortunately, the IRS offers a comprehensive comparison table of the FATCA and FinCEN rules, so you can determine if and what you need to report.

How to open an offshore bank account?

Opening an offshore bank account isn’t a complicated process. In fact, it’s a lot like opening an account at a local bank in the US in that the financial institution will require a lot of the same information, like:

  • Your name
  • Proof of address
  • Date of birth
  • Citizenship
  • Occupation

And like your local bank, they’ll require you to prove this information using a government issued ID—passport or driver’s license—and something like a utility bill or something similar.

You also may need to prove your income and investments with additional financial statements dating back anywhere from 6 to 12 months.

In the statements, they’ll review your transactions and look to see that you have a good record with your bank. The bank may also inquire as to what you intend to use the account for. This may seem invasive, but there has been increased international pressure to prevent illegal activity.

If you can provide all of that information, you should have no trouble opening an offshore account.

How much does it cost to open an offshore bank account?

Generally, most banks require a couple hundred US dollars and the documentation listed in the previous section. If you can meet those requirements, then you should be able to open an account in a matter of days.

But at only around $200 to $300, you may be thinking, “How do offshore banks make money then?” It’s a valid question.

Most offshore banks make money from foreign transaction fees when you transfer larger amounts of money into the bank.

Also, these financial institutions typically provide other financial services like in-house investments, brokerage accounts, and wealth management services that net bigger profits than their banking services.

Fortunately, it’s now easier than ever to research, investigate and transfer funds to any offshore bank you may consider a good fit for your needs.

When you open an offshore bank account, many times you have the option of choosing which currency in which you want to hold funds. However, holding funds in different currencies can come with consequences.

For example, if you earn interest on deposits in a foreign currency, you could create foreign tax liabilities. Also, if you’re constantly depositing and withdrawing in different currencies, you could be hit with exchange rate upcharges.

Remember, this is how offshore banks often make their money, so be sure to research the fee structure and upcharges of any potential offshore bank.

If you don’t like the rates offered by banks, look into a Wise multi-currency account. Wise allows you to move money between countries and exchange currencies at the mid-market rate. Plus, you can always pay in the local currency when you’re abroad.

Making deposits

People don’t often fly down to the Caribbean with thousands of dollars in their pocket, so most offshore bank accounts are almost exclusively funded via international wire transfer.

However, the ACH or domestic wire transfer system that allows you to transfer money for free in the US typically isn’t available when transferring money into an offshore account.

While it’s simple to make the transfer—usually just a point and click on your computer—account holders are often subject to international wire transfer fees when sending and receiving funds.

Withdrawing money

While depositing money may have few avenues, withdrawing your money is another story. Offshore banks provide a plethora of ways to withdraw your funds as a means of creating convenience for customers.

Most offshore banks provide international debit cards that allow you to access funds anywhere you go. This is another element you’ll need to research, as fees tied to using the card can add up quickly. If you’re going to use an ATM, it’s best to withdraw large sums of money at once to minimize the fees.

You may be able to get checks from the offshore bank, but it’s typically not preferred as the checks may not be accepted locally.

Most individuals with an offshore account use both a domestic and an offshore account in order to transfer funds locally for easy access. Doing things this way enables you to have more security and convenience with access to your local bank.

If you’re looking for a debit card where you can spend money with no foreign transaction fees, a Wise debit card is a solid option. With your Wise card, you can hold over 50 currencies for free and send money right from your balances. It’s designed for people who live, work, travel, or support family around the world—get a card today.

Frequently asked questions

Is it legal to have an offshore bank account?

Yes. It is legal to have an offshore bank account so long as you abide by the laws, rules, and regulations of both the US government and offshore jurisdictions of the account.

Offshore banking is just a blanket term for having a bank account outside of your home country. The same applies to an offshore company, it’s a company operating outside the jurisdiction of its headquarters. Neither of these practices are illegal for US citizens.

Are offshore bank accounts safe?

There is no easy answer whether offshore bank accounts are safe or not.

What we can suggest is that you use resources available to do your due diligence before putting money into any foreign bank account or investment. Some offshore banks may not offer the same asset protection as the US banking system.

The FDIC uses the CAMELS system to rate banks in the US and abroad, and while their rankings are confidential, the system they use is a good template for researching any bank.

CAMELS stands for:

  • Capital adequacy
  • Asset quality
  • Management
  • Earnings
  • Liquidity
  • Sensitivity

If you use your resources to research this information on any potential offshore bank, you should be able to make an informed decision.
