What does the FBAR Filing Trigger Checker actually compute?

This tool answers one narrow but high-stakes question. It checks whether the combined peak balance of your foreign financial accounts crossed $10,000 at any point during the calendar year, which is the line that triggers an obligation to file FinCEN Form 114, commonly called the FBAR. You enter the highest balance each non-US account reached during the year, the tool adds those peaks together, and it compares the aggregate to the $10,000 threshold. If the total reaches or exceeds that figure, the tool tells you a filing requirement is likely and points you to the FinCEN filing link. If the total stays under, it tells you no FBAR is triggered for that year.

The reason this matters is that the FBAR rule keys off the highest balance an account held, not the balance at year end and not the average. A single transfer that briefly inflated one account can pull your aggregate over the line even if the money left the same week. The checker is built around that quirk so you do not accidentally measure the wrong number. It is a screening tool, not a filing service. It exists to flag whether you should look closer and, where needed, complete the actual form through the FinCEN BSA E-Filing system that the result links to.

Who this tool is for, and who it is not for

Read this section before you trust the output, because it is the single most misunderstood point about the FBAR. The filing obligation applies to US persons. That means US citizens, US green-card holders, and individuals who meet the substantial-presence test for US tax residency. If you are one of those people and you own a Delaware LLC, your non-US bank accounts and brokerage accounts can pull you into FBAR territory. The checker is designed for you. It assumes the person entering balances is a US person trying to confirm whether their foreign accounts cross the threshold.

It is not built for the non-resident foreign owner of a US LLC. If you are a founder living outside the United States with no US person status, the FBAR rule does not reach your personal foreign accounts simply because you formed a Delaware company. Your accounts in your home country are not "foreign" to you in the sense the rule means, and you are not a US person who must report them. Many non-resident founders panic about FBAR when their real US filing duties run through different forms entirely, such as Form 5472 paired with a pro forma Form 1120 for a foreign-owned single-member LLC. If that describes you, this checker will usually return a result that does not apply to your situation, and the more relevant question is your 5472 obligation, not your FBAR one.

How to read each input field

The tool asks for one thing per account: the peak balance that account reached during the year, expressed in US dollars. Peak balance means the single highest amount the account held at any moment in the year, not the closing balance and not what sits there today. If your account is denominated in another currency, you convert the peak using the Treasury year-end exchange rate, which is the rate the FBAR instructions tell filers to use. Enter one row per account so the aggregation works correctly, and include every type of foreign financial account you control, not just checking accounts.

Foreign financial accounts are broader than many people expect. The category covers bank accounts, savings accounts, brokerage and securities accounts, certain pooled investment accounts, and accounts you hold a financial interest in or have signature authority over even if the money is not technically yours. It does not cover the value of your Delaware LLC itself, your US-based accounts, or physical assets like property. When you list accounts, separate them rather than combining, because the rule and this tool both work on the aggregate of individual peaks. Listing one merged figure can hide an account that should have been counted, or double-count a transfer that moved between two of your own accounts.

How to read the output

The output is a filing-requirement assessment, expressed in plain terms rather than a dollar score. When your aggregate peak is $10,000 or more, the tool reports that an FBAR filing appears to be triggered for that year and surfaces the FinCEN link so you can proceed. When the aggregate stays below $10,000, it reports that no FBAR is triggered. The threshold is not a per-account test. It is the sum across all your foreign accounts, so four accounts that each peaked at $3,000 push you to $12,000 aggregate and trigger the requirement, even though no single account ever held $10,000.

Treat a triggered result as a prompt to file, not as a calculation of any tax owed. The FBAR is an information report. Filing it does not create a tax bill by itself. A not-triggered result for one year does not lock in for future years either, because next year your balances may climb and the test resets annually. The assessment is a snapshot of one calendar year based on the numbers you typed. If you entered end-of-year balances instead of peak balances, the assessment can be wrong in either direction, so the accuracy of the output is only as good as your use of true peak figures.

A worked example: the brief spike that triggers a filing

Consider a US citizen who moved abroad and runs a Delaware LLC. She keeps a checking account in her country of residence that hovers around $4,000 most of the year. In March a client wires a $9,000 payment that lands in that same account before she sweeps most of it into her US business account a few days later. For those few days the account peaked near $13,000. Even though the account spent the rest of the year far below $10,000, the peak is what counts. Entering $13,000 as that account's peak, the tool reports a triggered FBAR for the year, because the highest balance crossed the line.

Now add a second account. She also holds a small savings account in the same country that peaked at $2,500. On its own that account is nowhere near the threshold. But the tool aggregates: $13,000 plus $2,500 is $15,500, comfortably over $10,000, so the filing requirement stands and now must list both accounts. The lesson the example teaches is that you cannot reason account by account or month by month. You collect each account's single highest point, you add them, and you compare the total once. The checker does that arithmetic so you do not talk yourself out of a filing by looking only at current balances.

A worked example: the non-resident founder who does not file

Take a founder who lives in Lagos, holds only Nigerian citizenship and residency, and forms a Delaware single-member LLC to invoice US clients. He keeps a Mercury account for the business and a personal bank account at home. He hears about FBAR and worries. When he runs the checker honestly, he first has to ask whether he is a US person. He is not. He is not a citizen, not a green-card holder, and does not meet the substantial-presence test. The FBAR obligation therefore does not attach to him, and his home-country bank account is not a reportable foreign account for FBAR purposes.

The practical takeaway is that his US compliance energy belongs elsewhere. As the foreign owner of a single-member US LLC treated as a disregarded entity, his core federal duty is the Form 5472 information return filed with a pro forma Form 1120, where missing the filing carries a $25,000 penalty. He should also confirm that BOI reporting does not apply, since US-formed LLCs have been exempt from beneficial ownership reporting under the FinCEN interim final rule issued March 26 2025. Using the FBAR checker, he confirms the tool does not apply to him and redirects his attention to the filings that do.

The rule the checker is built on

The $10,000 aggregate threshold comes from the Bank Secrecy Act framework that requires US persons to report foreign financial accounts to FinCEN. The report is FinCEN Form 114, filed electronically through the BSA E-Filing System rather than with your income-tax return. The test is whether the aggregate value of all foreign financial accounts exceeded $10,000 at any time during the calendar year. The word "exceeded" and the phrase "at any time" are doing the heavy lifting, and they are exactly why the tool measures peaks rather than balances at a single date.

Two features of the rule shape how you should use the checker. First, the threshold is aggregate, so the tool sums across accounts before testing. Second, the trigger is a high-water mark, so the tool wants the maximum each account touched. The FBAR is separate from your federal income-tax filing and separate from any state obligation tied to your Delaware LLC, such as the $300 franchise tax due June 1 or the $110 Certificate of Formation fee you paid at the start. None of those state items affect the FBAR test. The checker isolates the foreign-account question so you do not conflate it with company-level filings.

Common mistakes this tool helps you avoid

The errors that trip up filers are predictable, and the checker is structured to surface them. The most frequent is entering a year-end or current balance instead of the year's peak, which understates the aggregate and can hide a filing obligation. The second is treating the $10,000 line as a per-account test and concluding you are clear because no single account hit five figures, when in fact the aggregate did. The third is forgetting accounts you do not think of as yours, such as an account where you only hold signature authority, which still counts toward the test.

• Using closing balances rather than the highest balance each account reached during the year.
• Applying the $10,000 threshold per account instead of to the combined aggregate.
• Omitting brokerage, securities, or signature-authority accounts and counting only checking accounts.
• Assuming a non-US founder of a Delaware LLC must file when the FBAR applies to US persons.
• Converting a foreign-currency balance with a random rate instead of the Treasury year-end rate.
• Believing a prior year's not-triggered result carries forward, when the test resets each year.

Catching any one of these can be the difference between a clean year and a missed information return. The tool cannot read your bank statements for you, so the discipline of pulling true peak figures from each account is on you. What it does is enforce the correct arithmetic once you supply honest inputs.

Edge cases the threshold creates

Several situations sit right on the boundary and deserve care. Joint accounts are one: if you co-own a foreign account, the full value of that account generally counts toward your aggregate, not just your half, which can push you over the line faster than you expect. Transfers between your own accounts are another: if you move $20,000 from one foreign account to a second foreign account during the year, both accounts may show a high peak, and entering both peaks can overstate your true exposure unless you understand that the same dollars touched two accounts.

Currency conversion adds its own wrinkle. An account that hovered just under $10,000 in local-currency terms can cross the threshold once you convert at the Treasury year-end rate, or fall back under, depending on how the exchange rate moved. Dormant accounts you forgot about still count if they held value during the year. And the timing of a single large client payment, like the March wire in the earlier example, can make an otherwise quiet account a trigger. When your aggregate lands within a few thousand dollars of $10,000, treat the result as a signal to recheck each peak carefully rather than as a final verdict, because small input errors matter most near the line.

What to do once the tool says you are triggered

A triggered result means you file FinCEN Form 114 for that year through the BSA E-Filing System, which the tool links to from the result. You report each foreign account, its maximum value during the year, and the institution holding it. The FBAR is filed separately from your income-tax return and has its own deadline in the following year. Filing it is an information disclosure and does not by itself generate tax, but failing to file when required can carry significant penalties, which is the whole reason the threshold check is worth running every year.

Practical next steps after a triggered result include gathering each account's statements to confirm the true peak, noting the account numbers and institution names the form asks for, and recording your exchange-rate conversions. If you are a US person who also owns the Delaware LLC, keep the FBAR mentally separate from your company filings such as Form 5472 with the pro forma 1120 and the annual $300 franchise tax. They are different obligations to different agencies. If your situation is complex, for example accounts in several countries or signature authority over company accounts, treat the tool's triggered result as the start of a conversation with a tax professional rather than the end of the matter.

What to do when the tool says you are not triggered

A not-triggered result tells you that, based on the peaks you entered, your aggregate foreign-account value stayed under $10,000 for the year, so no FBAR is required for that year. That is a real and useful answer, but it carries two caveats worth keeping in mind. The result is only valid for the specific year and the specific figures you entered. If you used estimates rather than statement-verified peaks, recheck before you rely on the conclusion, because an account you rounded down could change the outcome.

The second caveat is that the test resets every year. A clean result in one year says nothing about the next, because balances change and a single large payment can push you over later. It is worth running the checker each year as part of your annual review, alongside the company items tied to your Delaware LLC such as the franchise tax due June 1 and confirming your Form 5472 position. For a non-resident founder, a not-triggered or not-applicable result is the expected outcome, and the more important annual task is making sure the filings that actually apply to a foreign-owned US LLC are handled on time.

How the FBAR differs from Form 8938

People often confuse the FBAR with IRS Form 8938, and the checker only answers the first of the two. Both reports deal with foreign financial holdings, but they live in different places and use different numbers. The FBAR is FinCEN Form 114, filed through the BSA E-Filing System, and it triggers on a $10,000 aggregate peak across foreign accounts. Form 8938 is an IRS form attached to your income-tax return, and it uses much higher thresholds that vary by filing status and whether you live in the United States or abroad. Because the two thresholds differ, you can owe one report and not the other in the same year.

The split matters for how you act on a result here. A triggered FBAR does not automatically mean a Form 8938 obligation, and a not-triggered FBAR does not clear you of 8938. The asset categories overlap but are not identical either, since Form 8938 reaches some assets the FBAR does not. If you are a US person whose accounts cross the $10,000 FBAR line, run the separate Form 8938 trigger check as well, because your foreign holdings may sit above one threshold and below the other. Treat this tool as the FinCEN side of the question only. The two reports can both apply, either can apply alone, or neither can apply, depending on your numbers and residence, so confirming one does not settle the other.

When is the FBAR due, and how does the extension work?

Once the checker tells you a filing is triggered, the next practical question is timing. The FBAR for a given calendar year is due the following April 15, the same calendar date as the federal income-tax deadline, but it is filed separately through FinCEN rather than with your return. Filers who miss April 15 receive an automatic extension to October 15 without having to request it, which gives most people a wide window to gather statements and complete the form. This automatic extension is specific to the FBAR and should not be confused with any extension you file for your income-tax return.

Knowing the deadline changes how you sequence your work after a triggered result. You do not have to file the moment the tool flags you, but you should not let the October backstop lull you into forgetting it either. A sensible approach is to confirm the trigger early in the year using verified peaks, then complete the FinCEN filing well before the October 15 fallback so a late client statement or a forgotten account does not push you up against the wire. Keep the FBAR deadline mentally separate from your Delaware LLC calendar, where the $300 franchise tax falls on June 1 and a miss there adds a $200 penalty plus 1.5% monthly interest. Those are different agencies on different dates, and the checker addresses only the foreign-account report, not any company-level filing.

Does signature authority over the LLC's business account count?

This is a subtle input question the checker depends on you getting right. The FBAR reaches not only accounts you own but accounts you have signature or other authority over, even when the funds are not personally yours. For a US person who controls a foreign business account held in the name of a company, that authority can pull the account into the FBAR picture. If your Delaware LLC or a related entity holds an account at a non-US institution and you can direct disbursements from it, that account's peak may belong in your aggregate, which is easy to overlook if you think only of personal accounts.

The careful move is to inventory every foreign account you touch, then decide for each whether you hold a financial interest, signature authority, or both, before you enter peaks. A few patterns deserve attention.

• A foreign business account where you are an authorized signer but not the legal owner of the funds.
• An account held jointly with a spouse or co-founder where the full balance, not your share, counts.
• An account opened for the company abroad that you forgot because day-to-day banking runs through a US provider.
• An account where your authority is shared, so more than one person may have a reporting duty for the same account.

Because a typical US-based provider account for a Delaware LLC is a US account, it does not enter the FBAR test at all. The signature-authority trap appears only when the institution is outside the United States. When in doubt about whether an account is foreign for this purpose, treat it as a flag to verify rather than a number to guess, since an omitted account that should have counted is the failure mode the rule punishes.

What records should you keep to back up the result?

A result from this tool is only as defensible as the figures behind it, so recordkeeping is part of using it well. For each account you entered, keep the monthly or periodic statements that show the highest balance the account reached during the year, because that peak is the number the FBAR asks for and the number an examiner would check. Save your currency conversions too, noting the Treasury year-end rate you applied and the date, so that if a foreign-currency balance sat near the line you can show how you arrived at the dollar figure. These records do not get filed with the form, but they support the entries you made.

Good documentation also protects you across years, since the test resets annually and patterns repeat. A simple habit is to keep one folder per year holding the statements, the conversion notes, and a copy of the completed FinCEN Form 114 if you filed one. That way a not-triggered year is supported by evidence rather than memory, and a triggered year has the backup that the form's figures rest on. If your situation also involves a foreign-owned Delaware LLC, store these FBAR materials alongside but distinct from your company records, such as the Form 5472 paired with the pro forma Form 1120 whose omission carries a $25,000 penalty. Keeping the two sets organized but separate mirrors how the obligations themselves are separate, and it makes any later review by a tax professional far quicker.

What is at stake if a triggered FBAR goes unfiled?

The reason a simple $10,000 threshold check is worth running every year is the consequence of getting it wrong. The FBAR is an information report, so filing it does not create a tax bill, but failing to file when the rule required it can expose a US person to penalties under the Bank Secrecy Act framework. That is why the checker errs toward flagging a likely obligation rather than reassuring you: a few minutes confirming your peaks and filing through FinCEN is far cheaper than discovering an unmet duty later. The tool's job is to make sure the question gets asked with the right numbers, using aggregate peaks rather than year-end balances.

The practical posture this suggests is to take a triggered result seriously and to take a near-miss result as a reason to double-check. If your aggregate landed close to $10,000, recheck each account's true high point and your conversions before concluding you are clear, because the cost of a wrong "under" is higher than the cost of filing a form you arguably did not need. For anyone with accounts in multiple countries, shared signature authority, or facts that do not fit cleanly, the right response to a triggered flag is to confirm the details with a tax professional rather than to rely on the screening result alone. The checker narrows the question and points you to the FinCEN system, but the filing itself, and the judgment near the edges, remain yours to complete.
