Introduction

US citizens with foreign bank accounts face two mandatory reporting requirements that are often confused. Furthermore, US and UK Tax Accountants must fully understand both FBAR (FinCEN Form 114) and FATCA (Form 8938). Additionally, confusing these two programs is a costly mistake. Consequently, this guide clarifies which form applies when and why both matter.

Compliance with both programs is non-negotiable for US citizens abroad. Furthermore, US and UK Tax Accountants specialists ensure the correct filing of both forms. Additionally, missing either form creates substantial penalties. Therefore, understanding both prevents filing errors and regulatory exposure.

FBAR Reporting — Form 114 Explained

What Is FBAR?

 The Foreign Bank Account Report, or FBAR, is sent to FinCEN rather than the IRS. Furthermore, the form is FinCEN Form 114 (also called FinCEN 114). Additionally, it reports all foreign financial accounts held by the filer. Therefore, FBAR is the primary account reporting requirement.

The Filing Threshold

File a FBAR if you have over £10,000 in aggregate foreign accounts at any point during the calendar year.  Additionally, tax accountants in the US and the UK are required to compute the aggregate across all accounts. Additionally, the threshold is approximately £10,000 USD equivalent. Therefore, even modest accounts might cross the threshold.

What Accounts Are Reported?

FBAR covers bank, investment, retirement, and savings accounts held abroad. Furthermore, it includes accounts with minimal balances if the aggregate exceeds £10,000.  Each owner also reports joint accounts in their entirety. Therefore, virtually all foreign financial accounts require FBAR reporting.

The Filing Deadline

 After the calendar year, FBAR is due on April 15 and is automatically extended until October 15. Furthermore, late filing carries substantial penalties ranging from £7,000 to £35,000+. Additionally, no extension beyond October 15 is available. Therefore, October 15 is the absolute final deadline.

FATCA Reporting — Form 8938 Explained

What Is FATCA?

FATCA (Foreign Account Tax Compliance Act) is reported on Form 8938 filed with the IRS. Furthermore, Form 8938 is filed as part of the US tax return on Schedule 1 (or separately). Additionally, FATCA broadly covers specified foreign financial assets. Therefore, U.S. and UK Tax Accountants must file FATCA alongside the income tax return.

The Filing Thresholds

FATCA thresholds depend on filing status and residency. Furthermore, single filers abroad must file if foreign assets exceed £200,000 at year-end. Additionally, married filing jointly abroad must file if assets exceed £300,000. Therefore, US and UK Tax Accountants must apply the correct threshold to each client.

What Assets Are Covered?

FATCA covers more than FBAR and includes stocks, bonds, mutual funds, real property, and cash equivalents.  Additionally, some retirement savings held overseas are subject to FATCA (with limitations). Additionally, the definition of a specified foreign financial asset is broader than FBAR’s account definition. Therefore, the FATCA score is the same as the FBAR score.

The Filing Deadline

Form 8938 is filed as part of the US tax return itself. Furthermore, it is due April 15 following the tax year. Additionally, the filing deadline coincides with the income tax return deadline. Therefore, file 8938 with your Form 1040.

FBAR vs FATCA — Key Differences

Who Reports to Whom?

FBAR is filed with FinCEN (a Treasury agency separate from the IRS). Furthermore, FATCA is filed with the IRS as part of the income tax return. Additionally, they are separate agency filings with different deadlines. Therefore, US and UK Tax Accountants must file both forms separately.

Account Scope Differences

FBAR covers all foreign financial accounts held by the filer. Furthermore, FATCA covers specified foreign financial assets (a broader category). Additionally, FATCA can include real property held abroad. Therefore, the FATCA scope exceeds that of the FBAR in many cases.

What Triggers Filing?

FBAR is triggered by £10,000 in accounts at any point during the year. Furthermore, FATCA is triggered by higher thresholds ranging from £200,000 to £600,000. Additionally, U.S. and UK Tax Accountants must check both thresholds for every client. Therefore, a client might owe FBAR but not FATCA, or both.

Penalties for Non-Compliance

FBAR Penalties

 Penalties for non-willing FBAR violations might reach £7,000 annually. Furthermore, wilful penalties can reach £35,000 or more per year of violation. Additionally, penalties are assessed per account violation. Therefore, US and UK Tax Accountants must stress the importance of FBAR to all clients.

FATCA Penalties

FATCA penalties are up to £10,000 per form (Form 8938) for failure to file. Furthermore, accuracy penalties can add another £10,000 per form. Additionally, penalties do not escalate year-by-year as FBAR penalties do. Therefore, FATCA penalties are generally lower than FBAR penalties.

The Compliance Benefit

Filing both forms correctly eliminates penalties. Furthermore, US and UK Tax Accountants specialists ensure the correct filing of both. Additionally, timely filing is the best strategy for avoiding penalties. Therefore, compliance is always the best option.

Common Mistakes to Avoid

Mistake One: Confusing FBAR and FATCA

Some clients file only FBAR and skip FATCA, or vice versa. Furthermore, both may be required for the same person. Additionally, missing one form creates substantial exposure. Therefore, file both if either threshold is met.

Mistake Two: Forgetting about Joint Accounts

Joint accounts with spouses or family members must be reported fully by each owner. Furthermore, many clients overlook joint accounts when calculating the aggregate threshold, leading to an incorrect calculation. Therefore, include all joint account balances in aggregate.

Mistake Three: Missing the October 15 FBAR Deadline

Some clients extend their income tax return but forget that FBAR has a final October 15 deadline.  Additionally, there is no chance of an extension past October 15. Additionally, missing this deadline is common. Therefore, explicitly calendar the October 15 FBAR deadline.

Mistake Four: Not Understanding Specified Assets

FATCA covers more than just bank accounts and includes real property, mutual funds, and stocks held abroad. Furthermore, many clients miss these items when calculating FATCA thresholds. Additionally, missing items create incomplete filings. Therefore, US and UK Tax Accountants must ask about all foreign assets, not just accounts.
