Holding a bank account in the United Kingdom presents United States tax residents with reporting obligations and potential tax liabilities that extend beyond routine account maintenance. Under U.S. tax law, citizens and resident aliens face an obligation to report foreign financial accounts and report income earned thereon, while enjoying certain treaty benefits and foreign tax credits that may mitigate double taxation. This article examines in detail the United States reporting requirements for a UK bank account, the United Kingdom’s treatment of non-resident interest income, strategies for mitigating double taxation through credits and treaties, penalties for non-compliance, and practical guidance—such as steps to open a UK bank account from USA and a guide for Americans to UK banking—for U.S. residents considering overseas banking.
U.S. Reporting Requirements for Foreign Accounts
U.S. persons who maintain a UK bank account must navigate two principal reporting regimes: the Report of Foreign Bank and Financial Accounts (FBAR, FinCEN Form 114) and the Foreign Account Tax Compliance Act (FATCA), specifically IRS Form 8938.
FBAR (FinCEN Form 114)
A U.S. person, defined to include citizens, resident aliens, and entities, must file an FBAR if the aggregate value of foreign financial accounts exceeds $10,000 at any point in the calendar year. “Whether the account produced taxable income has no effect on whether the account is a foreign financial account for FBAR purposes.” (IRS)
Penalties for failure to timely file can reach the greater of $12,499 or 50 % of the account balance per violation, with willful violations subject to criminal penalties. (IRS)
U.S. residents holding even a single UK savings or current account must therefore track daily balances to ensure the FBAR threshold is not breached inadvertently. Advice published by Greenback Tax Services underscores that “The FBAR is a reporting requirement, not a tax. You must file even if you have no income.” (Greenback Expat Tax Services)
FATCA (IRS Form 8938)
In addition to the FBAR, FATCA requires specified individuals to attach IRS Form 8938 to their annual Form 1040 when their foreign financial assets exceed statutory thresholds. For a single taxpayer living in the United States, the thresholds are $50,000 on the last day of the year or $75,000 at any point during the year; for married filing jointly, $100,000 and $150,000 respectively. (Greenback Expat Tax Services)
Taxpayers residing abroad face higher thresholds—$200,000 on the last day of the year or $300,000 at any point for single filers; $400,000 and $600,000 for joint filers. (Greenback Expat Tax Services)
Form 8938 reporting covers a broader range of assets, including foreign pensions and mutual funds, and filing failure can incur a $10,000 penalty, plus $10,000 for each 30-day non-compliance period up to $50,000, in addition to possible accuracy-related penalties. (Greenback Expat Tax Services)
United Kingdom Withholding and Treaty Considerations
UK Withholding Tax on Interest
UK domestic legislation imposes a 20 % withholding tax on “yearly” interest payments made to non-resident individuals, unless a double taxation agreement (DTA) provides for a reduced rate or exemption. “The UK imposes a 20 % withholding tax on non-residents who receive certain interest payments… The payer of any such amounts is liable for withholding and remitting this tax on behalf of the non-resident recipient.” (Dentons)
For retail deposit accounts held with UK banks, however, withholding typically does not apply to resident individuals; non-residents should file a claim to receive amounts gross. Under UK HMRC guidance, a non-resident may apply for exemption by citing the U.S.–UK DTA and providing a U.S. Taxpayer Identification Number. (GOV.UK)
Double Taxation Treaty
The UK–U.S. double taxation treaty generally limits UK withholding on interest to 0 % for “portfolio interest” paid to beneficial owners who are U.S. residents, provided proper documentation is submitted. Under Article 11(2) of the treaty, “Interest arising in a Contracting State and paid to a resident of the other Contracting State may be taxed in that other State.” (Wikipedia)
To benefit, U.S. residents must complete HMRC Form DT-Individual (R105) to claim treaty benefits when opening or maintaining a UK bank account.
U.S. Taxation of UK-Sourced Income
Worldwide Taxation and Foreign Earned Income Exclusion
The United States taxes its citizens and residents on worldwide income. Interest earned in a UK bank account must be reported on Schedule B of Form 1040. If the taxpayer qualifies as a bona fide resident of the UK or meets the physical presence test, up to $130,000 of foreign earned income may be excluded under Section 911, but this exclusion does not apply to passive interest income. (Wikipedia)
Foreign Tax Credit
To mitigate double taxation, U.S. persons may claim a foreign tax credit on Form 1116 for UK withholding tax paid on interest. The credit is generally limited to the U.S. tax liability on that income. For example, a U.S. resident earning £1,000 in interest taxed at 20 % in the UK (£200) may claim a credit against the U.S. tax on the $1,250 (approx.) of U.S. gross interest.
Penalties for Non-Compliance
Failure to comply with FBAR or FATCA reporting requirements carries severe penalties:
- FBAR: Civil penalties up to 50 % of the account value for willful violations; criminal penalties up to five years’ imprisonment and fines. (IRS)
- Form 8938: $10,000 penalty for failure to file; additional $10,000 per 30-day late period (max $50,000), plus potential 40 % accuracy-related penalty on understatements. (Greenback Expat Tax Services)
Taxpayers who discover unreported foreign accounts should consider the IRS’s Streamlined Filing Compliance Procedures to minimize penalties, particularly if non-willful. (IRS)

Compliance Checklist
| Requirement | Form | Threshold | Filing Date |
|---|---|---|---|
| Foreign Bank Account Report | FinCEN Form 114 | = $10,000 aggregate | April 15 (automatic Oct. 15 extension) (IRS) |

Ongoing Maintenance
- Track account balances daily to monitor FBAR thresholds.

- File timely extensions and amended returns if KYC or reporting requirements change, such as acquiring additional UK financial assets.
U.S. residents maintaining UK bank accounts must address dual regulatory frameworks: U.S. reporting (FBAR, FATCA) and UK non-resident withholding and DTA provisions. Accurate reporting on FinCEN Form 114 and IRS Form 8938, timely filing, and claiming foreign tax credits prevent penalties and optimize after-tax returns. Meanwhile, a clear understanding of the remote UK account opening guide, requirements for US residents opening UK bank accounts, and documents needed for UK banking as a US citizen ensures a seamless account setup. Observance of compliance obligations, prudent use of treaty benefits, and thorough documentation form the cornerstone of effective international banking for Americans.
