FBAR and FATCA Under Streamlined Foreign Filing Offshore Procedures: A Compliance Walkthrough

For Americans catching up on US taxes from abroad, two acronyms cause more confusion than any others: FBAR and FATCA. Both involve reporting foreign accounts and assets, both carry steep penalties, and both sit at the center of any submission under the Streamlined Foreign Filing Offshore Procedures. Getting them right — and getting them consistent with each other — is what separates a clean catch-up from a flawed one. This guide is a plain-English compliance walkthrough of FBAR and FATCA as they work inside the Streamlined Foreign Filing Offshore Procedures.

Context

The Streamlined Foreign Filing Offshore Procedures require six years of FBARs and, where thresholds are met, Form 8938 under FATCA on each of the three amended or delinquent tax returns. FBAR is filed with FinCEN; FATCA’s Form 8938 is filed with the IRS as part of the return. They overlap but are not the same, and the figures must reconcile. This walkthrough explains both, step by step.

The Streamlined Foreign Filing Offshore Procedures in Brief

The Streamlined Foreign Filing Offshore Procedures are the IRS pathway that lets non-willful US taxpayers living abroad catch up — filing three years of tax returns, six years of FBARs, and a Form 14653 certification, generally at a 0% penalty.

Within that package, FBAR and FATCA reporting do much of the heavy lifting. They are how the US government views a taxpayer’s foreign financial life, and a streamlined submission is, in large part, an exercise in ensuring that reporting is complete and accurate. The official terms are set out on the IRS streamlined filing compliance procedures (opens in new tab) page.

Why FBAR and FATCA Exist

It helps to understand why these two reports exist at all, because the reason explains why the IRS takes them so seriously.

FBAR dates back decades, to anti-money-laundering law: the US government wanted visibility of money held in foreign accounts. FATCA is newer and more powerful — it requires foreign banks themselves to report US account holders directly to the IRS. Together, they mean a US person’s foreign financial life is far more visible than many expats assume. That is precisely why a submission under the Streamlined Foreign Filing Offshore Procedures must get FBAR and FATCA right: the IRS is very often receiving the same data from the other side, and a submission that does not match what the banks have reported invites questions.

FBAR vs FATCA: Two Different Reports

The first thing to understand is that FBAR and FATCA are not the same report, even though people use the words interchangeably.

FBAR — the Report of Foreign Bank and Financial Accounts (opens in new tab), FinCEN Form 114 — is filed electronically with the Financial Crimes Enforcement Network, not the IRS. FATCA reporting, for individuals, means Form 8938 (opens in new tab), which is filed with the IRS as part of the tax return. They have different thresholds, different definitions of what counts, and different filing destinations. Under the Streamlined Foreign Filing Offshore Procedures, a taxpayer often has to do both.

The confusion is understandable because the two reports were created at different times for related but distinct purposes, and they have since overlapped. But treating them as interchangeable is a genuine compliance error. A taxpayer who files an FBAR and assumes FATCA is therefore covered — or the reverse — has a gap in their submission, and gaps are what the streamlined procedures are meant to close, not create.

FBAR: What It Is and Who Must File

e. A US person must file an FBAR for any year in which the aggregate value of their foreign financial accounts exceeded $10,000 at any point — even for a single day.

That aggregate test catches more people than they expect. Several modest accounts can cross the threshold together. Accounts that a taxpayer merely has signature authority over can count. Under the Streamlined Foreign Filing Offshore Procedures, six years of FBARs are filed, each listing every reportable account with its maximum value for the year, converted to US dollars.

It is worth dwelling on the aggregate test, because it is the part people get wrong. The $10,000 figure is not a per-account threshold; it is the combined high point across all foreign accounts. Someone with five accounts of $3,000 each has crossed it. So has someone whose single account briefly held $10,001 for one day before dropping back. The test is unforgiving precisely because it is designed to be simple to apply and hard to fall through.

FATCA Form 8938: What It Is and Who Must File

FATCA’s Form 8938 covers “specified foreign financial assets,” a broader category than FBAR. It includes foreign accounts but also reaches certain foreign investments, interests in foreign entities, and similar assets.

The Form 8938 thresholds are higher than the FBAR threshold and vary by filing status and residence — taxpayers living abroad have higher thresholds than those in the US. Within the Streamlined Foreign Filing Offshore Procedures, Form 8938 is attached to each of the three amended or delinquent returns where the taxpayer’s assets cross the relevant threshold for that year.

The breadth of Form 8938 is what particularly catches wealthy filers. Because it applies not just to accounts but also to interests in foreign entities and certain other foreign financial assets, a taxpayer with investments, company shares, or fund holdings can have a Form 8938 obligation even where their plain bank balances are modest. Within the Streamlined Foreign Filing Offshore Procedures, an honest inventory of assets — not just accounts — must come first.

How FBAR and FATCA Fit Into the Streamlined Submission

It helps to picture the whole package. The Streamlined Foreign Filing Offshore Procedures ask for three tax returns and six FBARs. FATCA’s Form 8938 lives inside the tax returns; FBARs are filed separately with FinCEN. The Form 14653 certification ties it together by explaining why the earlier failures were non-willful.

The reporting is therefore layered: six years of account reporting through FBAR, three years of asset reporting through Form 8938, and one narrative certification. A complete submission is one in which every layer is present, and all agree.

Step-by-Step: The FBAR Side of the Walkthrough

• Identify every foreign, brokerage, certain pensions, and accounts with signature authority.
• Find the maximum value. Determine the highest balance of each account during each year.
• Convert to US dollars. Use the appropriate year-end Treasury exchange rate consistently.
• Apply the aggregate test. If all accounts together exceeded $10,000 at any point, an FBAR is due.
• File six years electronically. Submit each year’s FinCEN Form 114, marked as part of the streamlined submission.

Step-by-Step: The FATCA Side of the Walkthrough

• Inventory specified foreign financial assets plus foreign investments and entity interests.
• Check the threshold for each year. Apply the Form 8938 threshold for your filing status and residence.
• Value the assets. Determine values in US dollars for each relevant year.
• Complete Form 8938. Attach it to each of the three streamlined tax returns where the threshold is met.
• Cross-check against the FBAR. Make sure the accounts on both forms tell a consistent story.

Why Consistency Between Forms Matters

This is the point most do-it-yourself filers miss. FBAR and Form 8938 overlap, and the IRS can see both. If an account appears on a Form 8938 but not on the matching FBAR, or balances differ without explanation, the inconsistency is exactly the kind of red flag that draws attention.

A well-built submission under the Streamlined Foreign Filing Offshore Procedures treats FBAR, Form 8938, and the income reported on the returns as a single coherent dataset. Every account is accounted for, every value is reconciled, and the whole package tells a single, consistent story.

There is a practical way to think about this. Imagine the IRS placing your FBARs, your Form 8938s, your tax returns, and the data it received directly from your foreign banks side by side on a desk. If all four agree, the submission looks exactly like what it is — an honest catch-up. If they do not, the gaps invite exactly the scrutiny the streamlined program is meant to avoid. Consistency is not tidiness; it is the credibility of the whole filing.

What FBAR and FATCA Do Not Cover

It is just as useful to know the limits of these reports. Neither FBAR nor FATCA, on its own, reports income. They are disclosure forms — they tell the government that an account or asset exists. The income generated by the account is reported separately on the tax return.

This matters within the Streamlined Foreign Filing Offshore Procedures because a complete submission has to do both jobs: disclose the accounts and assets through FBAR and Form 8938, and report the related income on the three tax returns. A taxpayer who files perfect FBARs but omits interest or dividends on the return has not yet finished the job. Disclosure and income reporting are two halves of the same obligation.

Common FBAR and FATCA Mistakes

The most common mistake is missing accounts — forgetting a small or dormant account, or one held only with signature authority. The second is currency conversion errors, where rates are applied inconsistently across years. The third is treating FBAR and FATCA as a single report and filing only one. The fourth is mismatched figures between the forms. The fifth is to omit Form 8938 entirely because the taxpayer assumed the FBAR was sufficient. Each undermines an otherwise sound, streamlined submission. The reassuring news is that every one of these mistakes is avoidable: each comes from a gap in the review process, not from anything inherently difficult, and a methodical walkthrough catches them all.

Case Study

An American teacher in the UK came to the Streamlined Foreign Filing Offshore Procedures believing she had only one reportable account. A proper review found four: a current account, a savings account, a workplace pension, and an old account she had forgotten. Together, they comfortably exceeded the FBAR threshold, and her assets crossed the Form 8938 line in two of the three years. Once every account was identified, consistently valued, and reported on both forms, her submission was complete and internally consistent — and her catch-up closed cleanly with a 0% penalty.

Her reaction afterward was telling. She had assumed the hard part would be the tax; in fact, she owed very little. The real work had been the disclosure — finding and reconciling every account — and that is the part she could not have completed confidently alone.

Frequently Asked Questions

What is the difference between FBAR and FATCA? FBAR is the FinCEN Form 114 report of foreign accounts, filed with FinCEN. FATCA reporting for individuals means filing Form 8938 with the IRS as part of the tax return, which covers a broader range of foreign assets.

How many years of FBARs are needed for streamlined filing? Six years of FBARs are required under the Streamlined Foreign Offshore Procedures, alongside three years of tax returns.

What is the FBAR filing threshold? An FBAR is due for any year in which the aggregate value of all foreign financial accounts exceeded $10,000 at any point during the year.

Do I need to file both FBAR and Form 8938? Often yes. They have different thresholds and definitions, and many taxpayers cross both, so a streamlined submission frequently includes both.

What are the Form 8938 thresholds for expats? They exceed the FBAR threshold and vary by filing status, with taxpayers living abroad having higher thresholds than those in the US.

What happens if my FBAR and Form 8938 do not match? Inconsistencies between the forms are a red flag for the IRS, so accounts and values must be reconciled across both within the submission.

Are pensions reportable on FBAR and FATCA? Many foreign pensions are reportable, depending on their structure. Pension reporting can be complex and is an area where specialist advice is valuable.
