What does the Form 8938 trigger checker actually decide?

This tool answers one narrow question: based on the foreign financial assets you hold, your tax filing status, and whether you live inside or outside the United States, are you required to attach IRS Form 8938 to your federal income tax return for the year? It is not a tax return, it is not advice on how much tax you owe, and it does not file anything for you. It runs your numbers against the published thresholds for the Statement of Specified Foreign Financial Assets and returns a plain yes or no, with the threshold that applied to your situation. The check matters because Form 8938 is an information return tied to FATCA, and the rules switch depending on two variables most people get wrong: filing status and country of residence. A single filer living in the US crosses the line far sooner than a married couple living abroad, so a generic rule of thumb tends to produce the wrong answer.

For the typical reader of this site, a non-resident founder of a Delaware LLC, the most useful output is often that you are outside the scope entirely. Form 8938 applies to US persons, which means US citizens and US tax residents. A non-resident alien with no green card and no substantial presence in the US is generally not a US person and is not subject to Form 8938 at all, no matter how large the foreign account balances are. The tool surfaces that distinction instead of letting you guess. If you are a US person, it then measures your assets against the correct dollar line so you know whether the form belongs on this year's return.

Who counts as a US person for this form, and who does not?

The threshold math only runs once you are inside the group the form covers. Form 8938 reaches US persons, and that category is narrower than people expect. It includes US citizens, lawful permanent residents who hold a green card at any point during the year, and anyone who meets the substantial presence test by spending enough days physically in the United States across a rolling three-year window. If none of those describe you, you are a non-resident alien for this purpose and the form does not apply to you, which is exactly what the residence input on this tool is meant to capture. Many founders incorporate a Delaware LLC while living and working entirely outside the US, never set foot in the country, and hold no green card. Those founders are non-residents and fall outside Form 8938.

The trap is assuming that owning a US company makes you a US person. It does not. A single-member Delaware LLC owned by a non-resident is a separate question from your personal tax status, and the LLC itself does not file Form 8938. Where the LLC owner does have US filing duties, those usually run through Form 5472 paired with a pro forma Form 1120, not Form 8938. Keep the two ideas apart: Form 5472 reports certain transactions between the foreign owner and the US LLC and carries a $25,000 penalty for failure to file, while Form 8938 reports a US person's own foreign assets. This tool only speaks to the second of those.

How to read the foreign asset value input

The asset value field is asking for the total value of your specified foreign financial assets, expressed in US dollars. Specified foreign financial assets cover more than bank accounts. They include foreign deposit and custodial accounts, foreign stock or securities held outside a financial account, an interest in a foreign entity, and certain foreign financial instruments and contracts with a non-US counterparty. They do not include a foreign account held at a US branch of a foreign bank, directly held foreign real estate, or physical assets like art or gold held directly. When you enter a number, you are entering the aggregate of the qualifying items, converted to US dollars using a defensible year-end exchange rate for the year-end measure and the relevant rate for any high-water mark.

Two separate measurements feed the test, and both matter. The first is the value of your assets on the last day of the tax year. The second is the highest value the assets reached at any point during the year, even if only for a single day. The form can be triggered by either one. That is why a balance that looks small on December 31 can still pull you into a filing requirement if a large sum passed through the account mid-year, for example a property sale, an investment round, or a loan that was received and then spent. Enter values that reflect both your year-end position and your peak position so the tool can test the correct line against each.

The thresholds the tool checks, line by line

The dollar lines are not a single number. They depend on filing status and on whether you live in the US or abroad, and the tool selects the matching pair for you. The published thresholds the checker applies are:

• Single filer or married filing separately, living in the US: file if assets exceed $50,000 on the last day of the year, or exceed $75,000 at any time during the year.
• Married filing jointly, living in the US: file if assets exceed $100,000 on the last day of the year, or exceed $150,000 at any time during the year.
• Single filer or married filing separately, living abroad: file if assets exceed $200,000 on the last day of the year, or exceed $300,000 at any time during the year.
• Married filing jointly, living abroad: file if assets exceed $400,000 on the last day of the year, or exceed $600,000 at any time during the year.
• Non-resident alien: not subject to Form 8938, so no threshold applies.

Read the comparison as strictly greater than, not greater than or equal to. An account that sits at exactly $50,000 at year-end for a single US filer does not cross the year-end line by itself. The any-time line is the one that catches people, because it looks back over the whole year rather than at a single date. Notice how much the abroad thresholds differ from the in-US thresholds: a US citizen living overseas has a year-end line four times higher than the same person living stateside. That is why the residence input is not cosmetic. Picking the wrong residence flips you between two thresholds that can be hundreds of thousands of dollars apart.

A worked example: a US-citizen founder living abroad

Suppose you are a US citizen who moved to Lisbon, files as single, and owns a Delaware LLC plus personal foreign accounts. Across the year your foreign bank balances and foreign-held brokerage assets peaked at $240,000 in March when a client paid a large invoice, then settled to $90,000 by December 31 after you paid contractors and taxes. You select married filing separately or single, living abroad. The tool checks the year-end figure of $90,000 against the $200,000 abroad line and finds it under. It then checks the peak of $240,000 against the $300,000 abroad any-time line and finds it under as well. The result is that you are not required to file Form 8938 for that year, even though the mid-year peak felt large. The abroad thresholds absorbed it.

Change one fact and the answer flips. Imagine the same person had not yet moved and was still living in the US for that tax year. The single, in-US lines are $50,000 at year-end and $75,000 any-time. The $90,000 year-end balance already clears the $50,000 line, and the $240,000 peak clears the $75,000 line many times over. The tool would return a filing requirement. Same assets, same person, different residence, opposite result. This is the single most common reason a founder reaches a wrong conclusion on their own: they apply the threshold for the wrong country of residence.

A worked example: a non-resident owner of a Delaware LLC

Now take the reader this site serves most often. You live in Karachi, have never held a green card, and have not spent meaningful time in the US. You formed a single-member Delaware LLC, paid the $110 Certificate of Formation fee, and obtained a free EIN by filing Form SS-4, which typically takes around 8 to 10 business days for a foreign owner without a US Social Security number. Your business and personal accounts at a fintech such as Mercury, Wise, Relay, Lili, or Payoneer, plus accounts back home, total well into six figures. You enter your asset values, select your filing status, and mark that you are a non-resident. The tool returns that Form 8938 does not apply to you, because you are not a US person. The balances are irrelevant to this particular form.

That does not mean you have no US filing duties. A non-resident-owned single-member US LLC is generally treated as a disregarded entity that must file Form 5472 together with a pro forma Form 1120 to report reportable transactions with its foreign owner, and missing that filing carries a $25,000 penalty. You may also have home-country reporting on the same accounts. The point of running this checker is to take Form 8938 off your worry list with a clear answer rather than carrying an open question, while keeping the obligations that genuinely do apply to you in focus.

Why the rule exists and what fee or penalty sits behind it

Form 8938 comes from FATCA, the Foreign Account Tax Compliance Act, which pushed US persons to disclose financial assets held outside the US so the tax authority can match individual disclosures against what foreign institutions report. The form is informational, so filing it does not create tax on its own. What it does create is exposure if you were required to file and did not. The failure-to-file penalty starts at $10,000, and it can climb by an additional $10,000 for each 30-day period after notice once the deadline has passed, up to a further $50,000. There are also accuracy-related consequences and an extended statute of limitations when the form is missing, which means the years in question stay open to review for longer.

Because the downside is a flat penalty rather than a percentage of tax, the cost of guessing wrong is the same whether or not you actually owed any tax. That asymmetry is the reason a quick threshold check is worth running every year your situation changes. The tool is built directly on the published threshold pairs and the US-person scope rule, so the yes or no it returns reflects the same lines the form instructions use. It does not estimate the penalty for you, and it does not decide the related questions about other forms; it isolates the trigger so you can act on a clean answer.

Form 8938 versus the FBAR: two different filings

People routinely confuse Form 8938 with the FBAR, FinCEN Form 114, and they are not interchangeable. The FBAR is filed with the Treasury, not attached to your income tax return, and its trigger is an aggregate of more than $10,000 across foreign financial accounts at any point in the year. Form 8938 is attached to your federal income tax return, covers a broader set of specified foreign financial assets, and uses the much higher status-based thresholds this tool checks. It is entirely possible to owe one and not the other, or to owe both, on the same set of accounts.

• FBAR threshold is a single $10,000 aggregate line, with no separate married or abroad tiers.
• Form 8938 thresholds range from $50,000 up to $600,000 depending on status and residence.
• The FBAR counts financial accounts; Form 8938 also counts foreign stock, foreign entity interests, and certain instruments held outside an account.
• The FBAR goes to FinCEN; Form 8938 rides along with your income tax return.

This checker answers only the Form 8938 question. If it returns that you must file Form 8938, treat the FBAR as a separate item to evaluate on its own much lower threshold, because clearing the FBAR line does not by itself put you over the Form 8938 line, and being under the Form 8938 line does not excuse an FBAR. Keeping the two filings mentally separate prevents the most expensive mix-up in this area.

Common mistakes that flip the result

The errors that change a correct answer into a wrong one cluster around a few inputs. Watch for these:

• Using the year-end balance only and ignoring the any-time peak, which understates assets and can hide a triggered filing.
• Selecting in-US residence when you actually qualify under the abroad test, or the reverse, which swaps you onto thresholds that differ by hundreds of thousands of dollars.
• Assuming that owning a US Delaware LLC makes you a US person; ownership of a US entity does not change your personal tax residence.
• Counting assets that are not specified foreign financial assets, such as directly held foreign real estate or an account at a US branch of a foreign bank.
• Forgetting to convert balances to US dollars, or using a convenient rate instead of a defensible one for the relevant date.
• Treating a non-resident result as covering Form 5472, the FBAR, or home-country filings, which it does not.

Each of these maps to a single input on the tool, so the fix is to slow down on the residence selector and the asset figure rather than rushing to the result. If two of your inputs are uncertain, run the check twice with each reasonable assumption and see whether the answer changes. If both versions return the same answer, your uncertainty did not matter for this year. If they diverge, you have found the exact fact you need to nail down before you rely on the output.

Edge cases the checker helps you spot

Several situations sit close to the lines and deserve a careful second look. A dual-status year, where you became or ceased to be a US person partway through the year, splits the period into a resident part and a non-resident part, and only the resident portion is in scope for Form 8938. A married couple where one spouse is a US person and the other is not has to decide whether they file jointly, which would apply the joint thresholds, or separately, which applies the single or married-filing-separately lines. Jointly owned assets and assets reported on a separate FBAR can be double counted by accident, so the aggregate you enter should reflect your reportable interest without inflating it.

Another edge case is the mid-year liquidity event. A founder who receives an investment, a loan, or a large customer payment and then deploys it within weeks can show a modest year-end balance and still cross the any-time line. The tool catches this only if you enter the true peak rather than the closing figure. Currency swings are a quieter version of the same problem: a balance that was under the line in local currency can cross it after conversion if the dollar weakened during the year. When any of these apply, the safest move is to enter the higher defensible figure and let the any-time threshold do its job, then confirm the edge case with a preparer before filing or skipping the form.

What to do once the tool gives you an answer

If the result is that Form 8938 does not apply, because you are a non-resident or because your assets sit under both the year-end and any-time lines for your status, record the figures and the date you ran the check. A non-resident founder can then shift attention to the filings that do apply, which commonly means Form 5472 with a pro forma Form 1120 for a foreign-owned single-member LLC, the federal income tax position of the business, and any home-country reporting on the same accounts. Keep in mind that BOI reporting under the Corporate Transparency Act has been exempt for US-formed LLCs since the FinCEN interim final rule of March 26, 2025, so a domestic Delaware LLC does not file a BOI report, which is a separate question from Form 8938 either way.

If the result is that you must file, attach Form 8938 to your federal income tax return for that year rather than sending it separately, and gather the supporting detail the form asks for: account numbers, institution names, maximum values, and the income items associated with each asset. Then evaluate the FBAR on its own $10,000 line as a distinct filing. Because the failure-to-file penalty for Form 8938 starts at $10,000 and can grow after notice, a triggered result is worth acting on promptly rather than leaving the form off and hoping the year stays unreviewed. The tool gives you the trigger; the response is to file the information return on time and keep the worked numbers in case anyone later asks how you reached the conclusion.
