Key US regulations for international wire transfers

FATCA (Foreign Account Tax Compliance Act):
Requires institutions to report foreign financial assets held by US citizens.

FBAR (Foreign Bank Account Report):
Mandatory for foreign accounts exceeding $10,000.

Bank Secrecy Act:
Requires institutions to report large or suspicious transactions.

The Patriot Act:
Adds further due diligence requirements to verify identities and monitor cross-border activity.

These international wire transfer regulations help ensure transparency and security in global financial transactions.

Foreign Account Tax Compliance Act

FATCA is a US tax law¹ that requires both foreign financial institutions and certain non-financial entities to report foreign assets and bank accounts held by US citizens or residents. This applies to all accounts, whether temporary, permanent or jointly held—they must be disclosed.

Aside from institutional reporting, individuals are required to report their foreign financial assets on annual tax returns if the value exceeds specific thresholds. The Financial Crimes Enforcement Network (FinCEN)² states you must file FBAR if your combined foreign account balances reach $10,000 or more at any point during the year, even if it was just for a single day.

The Consumer Financial Protection Bureau (CFPB)

The CFPB³ is a US government agency created to enforce federal consumer financial laws and hold violators accountable. Its purpose is to protect consumers in the financial marketplace by making sure companies play by the rules.

Beyond enforcement, the CFPB also provides educational tools that help people make informed decisions. It works to ensure transparency, fairness, and accountability across the financial industry.

Money transfer limits to keep your transaction unreported

Financial institutions and money transfer services are required to report international transactions that exceed $10,000 (under the Bank Secrecy Act).

Transfers under that threshold typically don't trigger an automatic report, but that doesn't mean they go unnoticed. Banks are still responsible for monitoring transactions for suspicious activity. For example, if someone tries to avoid reporting by splitting large transfers into smaller ones—known as "structuring"—that can raise red flags and lead to further scrutiny.

This type of oversight helps authorities detect and prevent fraud, money laundering, and tax evasion. You can learn more about this from the Office of the Comptroller of the Currency.⁴

What are the requirements for a wire transfer?

You'll need to provide specific information per international wire transfer regulations. While requirements vary by provider, here's what you can generally expect.

Basic identity verification: Your full name, address, and a valid government-issued ID.
Recipient information: Most services will require the recipient's full name, bank account details, and, in some cases, their address or phone number.
Purpose of the transfer: Some providers ask why you're sending the money, especially for international or high-value transactions.
Additional documentation for large transfers: If you're sending more than $10,000, be prepared to provide extra paperwork. That might include proof of income, bank statements, or payslips to verify your source of funds.

Online transfers may come with stricter verification steps to ensure security, especially for first-time users or unusually large amounts. Always check the specific needs of the platform or bank you're using to avoid delays.

What is the limit for an international wire transfer?

There is no official international money transfer limit or federal law that limits the amount of money you can send or receive.

However, banks and money transfer providers often impose their own limits, which vary depending on the platform, the amount, the payment method, and the destination country. Some services may set daily caps at $3,000, while others offer higher limits for verified users.

For example, BOSS Money lets you send between $10 and $2,999 via the app or up to $10,000 at a retail location in the United States. These limits may vary based on the recipient's country and the selected delivery method. New users also get $0 fees on their first two transfers (each up to $2,999) when using a debit card through the app.

Apps like BOSS Money are often faster and more affordable than traditional bank wires. Additionally, it's essential to understand your rights as a consumer. You have the right to transparent pricing, including a clear view of exchange rates, fees, and any additional charges before confirming your transfer.

Not all providers display this information upfront. So, take a moment to review the details.

Paperwork needed when transferring more than $10,000

Suppose you send or receive international wire transfers tied to foreign financial accounts totaling more than $10,000. In that case, you are legally required to report them to comply with US international wire transfer regulations.

Simply receiving money from abroad can be enough to trigger reporting requirements under laws like FATCA. You may even need to file different forms for tax compliance. Here are the most common ones:

FBAR (FinCEN Form 114): Required if total foreign financial accounts surpass $10,000 at any time during the calendar year. You must file this form electronically with FinCEN.
IRS Form 8938 (Statement of Specified Foreign Financial Assets): Required under FATCA for individuals with foreign assets above certain thresholds, which vary depending on filing status and residency.
Form 3520: Used to report foreign gifts or inheritances over IRS-specified thresholds.
Form 3520-A: You may require this form in addition to Form 3520 if you're involved with a foreign trust.

Not filing the correct forms can result in serious consequences, including fines, audits, or even a criminal investigation. And these aren't the only things to consider. Other international wire transfer regulations, including those under the Patriot Act and Bank Secrecy Act, may also apply, depending on the transaction.

To avoid costly mistakes, consult a tax attorney or international tax professional. They can help determine which forms apply to your situation and ensure everything is correct.

When is a money transfer considered a gift?

A money transfer is considered a gift by the IRS when the sender provides funds without expecting anything in return—no goods, services, or repayment. And while gifts must often be reported, they are not always subject to tax.

In general, the person giving the gift (the donor) is responsible for paying any applicable gift tax, not the recipient. However, in certain situations, the recipient may choose to cover the tax instead.

It's best to consult a qualified tax professional if you're considering this type of arrangement.

Here are several key exceptions to taxation for gifts.

Gifts to your spouse
Payments made directly for someone's tuition or medical expenses
Donations to political organizations
Contributions to qualified charitable organizations

Also, any gift that falls below the IRS annual exclusion limit isn't taxable. This exclusion amount may change from year to year, so it's essential to verify the current threshold⁵ before sending or receiving large transfers.

Consequences of non-compliance

Non-disclosure may trigger a tax audit or, in more severe cases, a criminal investigation.

If you fail to report qualifying accounts or transactions, you may face civil or criminal penalties. These may include fines, restitution orders, or even jail time. Under Form 8938⁶ filing requirements, the IRS may impose a $10,000 fine for failing to disclose foreign financial assets. If you continue to ignore your reporting obligations after being notified, you may face additional fines of $10,000 for every 30 days the issue remains unresolved.

In some cases, you can avoid penalties by showing reasonable cause for non-compliance with international wire transfer regulations. However, this doesn't apply if the omission involves illegal activity abroad.

The best way to avoid penalties is to stay compliant with FATCA and related international wire transfer regulations. Report your foreign accounts, file the correct forms, and when in doubt, consult a tax professional to ensure you're following the rules.
