U.S. expats with foreign accounts may be required to file Schedule B with their income tax return. This tax form is used to report interest or dividends and determine whether a taxpayer has financial interest in foreign accounts. Additionally, Part III of Schedule B asks whether a taxpayer must file an FBAR (Report of Foreign Bank and Financial Accounts).
Failure to file Schedule B when required can result in penalties. Understanding the filing requirements is crucial for taxpayers with foreign financial accounts.
What Is Schedule B?
Schedule B is a tax form attached to Form 1040 to report interest and ordinary dividends received during the tax year. It applies to taxpayers who have:
- Taxable interest or dividend income
- A foreign bank account or other financial accounts in a foreign country
- Financial interest or signature authority over a foreign bank and financial account
- A foreign trust
If any of these apply, taxpayers are required to file Schedule B with their income tax return.
When Must Schedule B Part III Be Completed?
Schedule B Part III asks about foreign bank accounts and trusts. Taxpayers must complete Part III if they:
- Have a foreign bank account or other financial accounts in a foreign country.
- Have signature authority or financial interest over foreign bank accounts.
- Are required to file an FBAR (Financial Crimes Enforcement Network (FinCEN Form 114).
- Hold an interest in a foreign trust.
If any of these apply, the taxpayer must report foreign accounts on Schedule B and indicate whether they are required to file an FBAR. If the aggregate value of all foreign financial accounts exceeds $10,000 at any time during the calendar year, the taxpayer must also file an FBAR (FinCEN Form 114).

How Do I Know If Schedule B Is Required?
You must file Schedule B if:
✅ Your taxable interest or dividend income.
✅ You have a foreign bank account, brokerage account, or securities account.
✅ You have financial interest in or signature authority over foreign accounts.
✅ You hold foreign financial assets in a foreign bank or other financial institution.
✅ You have interest in a foreign trust.
If you answer “Yes” to any of these, you are required to file Schedule B with your tax return.
The Schedule B compliance requirement for foreign accounts ensures that U.S. taxpayers properly report interest or dividends and disclose foreign bank accounts. Failing to file Schedule B or report foreign accounts can lead to IRS scrutiny and penalties.
To avoid costly mistakes, taxpayers should review filing requirements, ensure they file an FBAR if required, and consult a tax professional if unsure. Complete Schedule B correctly to remain in compliance with U.S. tax laws.
