BOI Report 2026: complete guide to FinCEN Beneficial Ownership filing

21 March 2025: FinCEN's interim final rule made the BOI Report no longer mandatory for US-formed LLC owned by non-residents. Only foreign reporting companies (formed outside the US and registered in a state) remain in scope. For greater privacy we recommend not filing voluntarily.

The BOI Report has been the most volatile compliance topic for US LLC since the CTA took effect. Here's the complete current guide, updated for the March 2025 FinCEN interim final rule that re-scoped the obligation.

What the BOI Report is and why it was created

The Beneficial Ownership Information (BOI) Report was mandated by the Corporate Transparency Act (CTA), enacted in 2020 and originally effective January 1, 2024. Its purpose: create a federal registry of who actually owns and controls certain US-connected companies, to combat money laundering, tax evasion, and financial crime.

Before the CTA, it was possible to form a US LLC with no federal disclosure of ownership. The BOI Report was meant to change that, but after FinCEN's March 2025 interim final rule the scope was narrowed to "foreign reporting companies" (entities formed OUTSIDE the US and registered to do business in a state). FinCEN (Financial Crimes Enforcement Network) maintains the database of beneficial owners for entities still in scope. The database is NOT public; it's only accessible to law enforcement and authorized entities.

Who must file

Reporting companies in the current (post-March 2025) scope:

• Foreign reporting companies: entities formed outside the US and registered to do business in a US state
• They identify their beneficial owners (≥ 25 % ownership or substantial control)

Out of scope (no BOIR filing required today):

• Domestic US LLC, including single-member LLC owned by non-residents (Wyoming, Delaware, New Mexico, Florida or any supported state)
• US corporations formed in any state
• Entities already exempt under the CTA (banks, large operating companies with 20+ US employees + $5M+ US revenue + physical US office, regulated securities issuers, etc.)

For most of our clients: foreign-owned US-formed single-member LLC are NOT required to file the BOI Report under the current rule. We monitor FinCEN.gov on every engagement and, if the scope expands again, we file at no extra cost.

About the reporting company:

• Legal name (and any DBAs. "doing business as" names)
• State of formation
• Principal place of business address
• EIN

About each beneficial owner:

• Full legal name
• Date of birth
• Current residential address (not a business address)
• Unique ID number (passport, driver's license, or state ID)
• Image of the ID document (front and back if applicable)

Beneficial owner definition: Anyone who directly or indirectly owns 25%+ of the company, or who has substantial control over the company. For a single-member LLC, that's you. the sole owner.

Deadlines today

Companies formed before January 1, 2024: Under the original CTA framework, the initial BOI Report was due January 1, 2025. After FinCEN's March 2025 interim final rule, US-formed LLC owned by non-residents are out of scope, so this deadline no longer applies to them — if you never filed, there is nothing to "catch up" today. If your entity is a foreign reporting company and you missed the original window, ask for help: at Exentax we open the case, file what is missing and reply to the relevant authority for you.

Companies formed January 1, 2024 or later — only if in scope: if your entity is a foreign reporting company (formed outside the US and registered in a US state), the initial BOI Report is due within 30 calendar days of state registration. US-formed LLC owned by non-residents are out of scope under FinCEN's March 2025 interim final rule and are not bound by this window.

Updates: Any changes to reported information must be submitted within 30 calendar days of the change. This includes changes to your address, passport number, or any other reported information.

Penalties for non-compliance (only if you are in scope)

The penalties below apply only to entities currently in scope (foreign reporting companies registered to do business in a US state). A US-formed LLC owned by a non-resident is out of scope under the March 2025 rule and is not exposed to them. If you do fall in scope, here is what is at stake. Relax: at Exentax this is what we do every week, we close it before the letter ever lands in your inbox.

Civil: Up to $591 per day (inflation-adjusted) for each day the report is late.

Criminal: Up to $10,000 fine and up to 2 years in prison for willful violations.

These are serious penalties and FinCEN is actively enforcing compliance against in-scope filers. If your structure ever brings you back into scope, at Exentax we map the exposure early, prepare the reasonable-cause file and reduce avoidable escalation before the authority controls the timeline.

How to file

Online: Through FinCEN's BOSS system (BOI E-Filing System) at fincen.gov. The filing itself is free. no filing fee.

Method: Electronic filing only. No paper filing accepted.

At Exentax: Filing the BOI Report is not part of our default formation package, because after FinCEN's March 2025 interim final rule a US-formed LLC owned by a non-resident is out of scope and not required to file. We treat the BOI Report as your decision: for greater privacy our default recommendation is not to file voluntarily while your structure stays out of scope. If your entity does fall in scope as a foreign reporting company (or you choose to file anyway), we prepare and submit the report, handle the 30-day updates and archive the confirmation number for you.

Is the information public?

No. The BOI Report database is strictly controlled. Access is limited to:

• Federal, state, local, and tribal law enforcement (with proper authorization)
• Financial institutions conducting customer due diligence (with client consent)
• Government agencies authorized by FinCEN
• Foreign law enforcement through formal request channels

Your information is NOT on a public database. A random person cannot look up who owns your LLC through the BOI database.

today updates to watch

FinCEN continues to issue guidance and updates to BOI requirements. As of our last update:

• The core requirements remain as described above
• FinCEN is actively enforcing filing requirements
• Some litigation around the CTA has created uncertainty in certain areas. Exentax monitors developments and advises clients accordingly
• The deadline framework has stabilized after initial implementation challenges

Common BOI Report mistakes (only relevant if your entity is in scope)

These mistakes apply to foreign reporting companies still required to file. US-formed LLC owned by non-residents are out of scope under the March 2025 rule and are not exposed to them:

• Not filing at all when in scope: the most expensive mistake ($591/day)
• Filing with outdated information: failing to update within 30 days of changes
• Using business address instead of residential: the BOI Report requires your personal residential address
• Poor quality ID image: FinCEN may reject filings with unclear ID photos
• Filing late: even a few days late triggers the per-day penalty. At Exentax we map the exposure early, prepare the reasonable-cause file and reduce avoidable escalation before the authority controls the timeline.

BOI Report filing: step by step

At Exentax we do not file the BOI Report by default: under the current FinCEN rule (March 2025) a US-formed LLC owned by a non-resident is out of scope, and for greater privacy we recommend not filing voluntarily. If your entity falls in scope as a foreign reporting company, or if you decide to file even when not required, we prepare the submission, handle the 30-day updates and archive the FinCEN confirmation receipt in your legal file.

When you must update your BOI Report

If your entity is genuinely in scope, an updated BOI Report is generally due within 30 days of these changes:

• Change of beneficial owner (new member added, member removed)
• Change of beneficial owner's name (legal name change, marriage)
• Change of beneficial owner's address (you move)
• Change of beneficial owner's ID document (new passport)
• Change of LLC name
• Change of LLC address (Registered Agent change)
• Change of company applicant information

Important — only if you are in scope: if your entity is a foreign reporting company and you have already filed, failing to file an update carries the same penalties as not filing the initial report ($591/day, up to $10,000 + 2 years criminal). For US-formed LLC owned by non-residents the obligation does not currently apply, so neither does the update window. If you are in scope, at Exentax we track these triggers and file updates whenever you notify us of changes.

BOI Report exemptions

Some entities are exempt from BOI reporting:

• Companies with 20+ full-time US employees AND $5M+ in US revenue AND physical US office
• Publicly traded companies
• Banks, credit unions, and other regulated financial institutions
• Insurance companies
• Tax-exempt entities

How to read the BOI Report scope as a stable status rather than as a recurring surprise

The BOI Report reads more calmly when it's treated as a stable scope question rather than as a recurring surprise. For most US-formed LLC owned by non-residents the scope question has a single, persistent answer after the March 2025 interim final rule — out of scope, nothing to file — and the rest of the year is free of structural decisions about it. The pieces that matter are the entity's formation country, its state registration and any later change to those facts, since only those would move it into the foreign reporting company category.

A short, dated note in the LLC folder that records the current scope determination (and the FinCEN guidance version used to make it) makes the question reviewable in a few minutes whenever a counterparty asks for proof, and removes the temptation to file voluntarily "just in case" — which would unnecessarily expose personal data.

> Review my structure

Your US-formed LLC is almost certainly NOT in scope today. Under FinCEN's March 2025 interim final rule, single-member LLC formed in the US and owned by non-residents are out of the BOI Report obligation, and we treat any voluntary filing as your call — with privacy as our default recommendation.

How to read the BOI Report obligation as a stable filing rather than as a recurring uncertainty

The BOI Report obligation reads more calmly when it's treated as a stable filing tied to clearly defined triggering events rather than as a source of recurring uncertainty. The triggering events — initial filing, change in beneficial owner, change in identifying information — are limited and discrete, and once they're identified the filing becomes a well-defined task.

This reading replaces the impression of constant exposure with a small list of moments that require action, and leaves the rest of the year free of structural decisions about the BOI Report.

How to anchor the BOI Report file in the LLC documentation

The BOI Report file anchors more usefully in the LLC documentation as a separate section with its own dated versions, kept apart from current bookkeeping.

Legal & procedural facts

FinCEN and IRS reporting requirements moved recently; the current state is:

• BOI / Corporate Transparency Act: your LLC is NOT required to file (a competitive advantage). After FinCEN's March 2025 interim final rule, the BOI Report obligation was narrowed to "foreign reporting companies" (entities formed OUTSIDE the US and registered to do business in a state). A US-formed LLC owned by a non-resident does NOT file the BOI Report: one fewer filing on your calendar, less paperwork, and a cleaner structure than ever. If your LLC was formed before March 2025 and you already filed BOI, keep the acknowledgement. The regulatory status can change again: we monitor FinCEN.gov on every filing and, if the obligation comes back, we handle it at no extra cost. Current status verifiable at fincen.gov/boi.
• Form 5472 + pro-forma 1120. For a Single-Member LLC owned by a non-resident, the final regulations of Treas. Reg. §1.6038A-1 (in force since 2017) treat the LLC as a corporation for 5472 purposes. Procedure: pro-forma Form 1120 (header only: name, address, EIN, tax year) with Form 5472 attached. It is filed by certified mail or fax to the IRS Service Center in Ogden, Utah, not e-filed via standard MeF. Due date: April 15; extension via Form 7004 to October 15. Penalty: $25,000 per form per year, plus $25,000 per additional 30 days of non-filing after IRS notice.
• Substantive Form 1120. Only applies if the LLC has filed a check-the-box election to C-Corp (Form 8832): it then pays 21 % federal corporate tax and files a substantive 1120. A standard disregarded LLC does not file a substantive 1120 and does not pay federal corporate tax.
• EIN and notice. Without an EIN you cannot file 5472 or BOI. The IRS does not warn before imposing penalties; you find out when an EIN is flagged or a later filing is rejected. That is exactly why at Exentax we keep your calendar tight — you stop thinking about deadlines and we close them before they ever bite.

Legal and procedural facts

Read this section as a checklist with teeth: each point flags a real failure mode we have seen in cross-border LLC files. Skip none of them - most reassessments and account closures we clean up later trace back to one of these items.

Exentax today update: BOI Report at end-today

BOI has been the most volatile obligation of the past 24 months; the current version:

• Current status. The BOI Report is NOT required for US-formed LLC owned by non-residents after FinCEN's March 2025 interim final rule. The current scope covers only foreign reporting companies (entities formed outside the US and registered to do business in a state). If your entity falls in that bucket, it must identify the beneficial owner (anyone holding ≥ 25 % ownership or substantial control), be filed electronically and free of charge at boiefiling.fincen.gov, and be on time: 30 days from state registration and 30 days for any change of address, document or beneficial owner.
• Current penalties if in scope. USD 591/day inflation-adjusted for civil violations, up to USD 10,000 and/or 2 years in prison for willful violations (31 U.S.C. §5336). Only relevant when your entity is a foreign reporting company or if FinCEN re-expands the scope. And if a notice does land, at Exentax we keep the dossier ready so you reply in hours, not weeks.
• Filing operation if in scope. Free initial filing at FinCEN's official BOI filing portal, 10-15 minutes process, initial filing + 30-day update for any change of address, document or beneficial owner. Keep the BOIR Confirmation Number as proof.

Frequently asked questions

Does my U.S.-formed LLC with a Spanish member have to file the BOIR? No, not under the current rule. After FinCEN's March 2025 interim final rule, every US-formed LLC (Wyoming, Delaware, New Mexico or any other state) owned by a non-resident is out of scope of the BOI Report. Only foreign reporting companies file. We monitor FinCEN.gov on every filing and, if the obligation comes back, we handle it at no extra cost.

What is the penalty if I am in scope and file late? Up to USD 591 per day of delay (civil amount adjusted annually for inflation) and, for willful non-compliance, up to USD 10,000 and 2 years' imprisonment under 31 U.S.C. §5336. That is why, if you qualify as a foreign reporting company, filing on time matters and, if you have late BOIRs, you should regularize before any FinCEN notice arrives. And if a notice does land, at Exentax we keep the dossier ready so you reply in hours, not weeks.

What do I keep as evidence? The BOIR Confirmation Number that the boiefiling.fincen.gov portal returns once you submit, plus the transmission PDF. That is the standard proof in any future audit. That is exactly why at Exentax we keep your calendar tight — you stop thinking about deadlines and we close them before they ever bite.

Who exactly is a beneficial owner? Any individual who, directly or indirectly, owns ≥ 25 % of the LLC or exercises substantial control (such as a senior officer or a person with authority to bind the entity). For each one you must file legal name, date of birth, residential address and a current passport or government-issued ID number.

How does the 30-day update window work in practice? Any change to the data on file (new passport, new residential address, new member crossing the 25 % threshold, change of LLC name) opens a 30-day window to refile through boiefiling.fincen.gov. Skipping that update is treated by FinCEN like skipping the initial filing and exposes you to the same civil and criminal penalties. At Exentax we map the exposure early, prepare the reasonable-cause file and reduce avoidable escalation before the authority controls the timeline.

(2026) case study: BOI Report for an LLC with a Spanish owner after the IFR

After FinCEN's Interim Final Rule of March (2025), US-domestic reporting companies are exempt from BOI. Case: NM LLC with a single Madrid-resident owner. Because the owner is non-US, the LLC remains in scope only if it becomes a foreign reporting company through re-domiciliation. If it stays US-domestic, it is outside the regime. Deadlines: 30 days to report changes when applicable, civil penalties that can escalate materially and possible criminal consequences for willful failure. Now is the moment to ask for help. At Exentax we open the case, file what is missing and reply to the relevant authority for you.

How we file the BOI Report at Exentax without surprises

The FinCEN BOI Report looks simple and it is, but the mistakes we see weekly are always the same: beneficial-owner identities miscaptured, deadlines missed after corporate changes, and FinCEN ID copies that no one stores. This is where the Exentax method kicks in.

• Identity and document of the beneficial owner verified before any upload: legible passport, current residential address and a FinCEN ID assigned per person.
• 30-day update trigger: any change of address, passport or corporate structure opens the short refile window that most filers skip.
• Filing receipt: submission PDF and transmission number stored in the client repository, not the operator's inbox.

At Exentax, we review your real numbers in context: tax, banking, compliance, payments and money movement. The goal is not a pretty structure on paper, but a serious operating decision.

What if HMRC, the IRS or my local tax authority asks about my LLC?

It's the question every client raises in the first consultation, and the short answer is: your LLC isn't opaque, and a properly declared structure closes any inquiry in standard forms. Your tax authority can request the state Certificate of Formation (Wyoming, Delaware or New Mexico), the EIN issued by the IRS, the signed Operating Agreement, the Mercury or Wise statements for the year, the Form 5472 plus pro-forma 1120 you filed, and the bookkeeping that reconciles income, expenses and movements. If all of that exists and is delivered in order, the inquiry doesn't escalate.

What tax authorities do pursue, and rightly, is sham ownership (nominees, paper residency) and undeclared foreign accounts. A well-structured LLC is the opposite: you appear as beneficial owner in the BOI Report when applicable (verifiable at fincen.gov/boi), you sign the bank accounts and you declare the income where you actually live. The structure is registered with the state Secretary of State, with the IRS and, when European banks are involved, inside the CRS perimeter of the OECD standard.

The mistake that really sinks an inquiry isn't having an LLC; it's not attributing the income correctly in your domestic return, not declaring foreign accounts when the year-end balance exceeds the local threshold (€50,000 in Spain via Modelo 720; the equivalent FBAR / Form 8938 in the US for residents; T1135 in Canada), and not documenting related-party transactions between the member and the LLC. Those three fronts are worth closing before any request arrives, not after.

## What an LLC does NOT do

- It does not exempt you from tax in your country of residence. If you live in Spain, France, Germany or Portugal, you are taxed there on worldwide income. The LLC organises your US side (zero federal tax for non-resident SMLLC pass-through, absent Effectively Connected Income); it does not switch off your domestic taxation. The income tax is computed on the attributed profit, not on the dividends actually paid.

- It is not an offshore vehicle or a BEPS scheme. It is a US entity recognised by the IRS, registered in a specific state with physical address, registered agent and annual informational filings. Classic offshore jurisdictions (BVI, Belize, Seychelles) leave no public trace; an LLC leaves a trace in five different places.

- It does not protect you if you commingle funds. The pierce the corporate veil doctrine kicks in as soon as a judge sees the LLC and the member behaving as the same wallet: mixed accounts, personal expenses paid from the LLC, no signed Operating Agreement, no bookkeeping. Three suspicious transactions are enough.

- It does not save you social security contributions at home. If you are self-employed in Spain, France or Germany, your monthly social contribution remains identical. The LLC handles the trading side with international clients; your personal contribution is independent.

- It does not exempt you from declaring foreign accounts. Spain residents file Modelo 720 / 721; UK residents, the SA106; Portugal residents, the Anexo J of Modelo 3 IRS; Germany residents, the Anlage AUS. Those obligations belong to the individual, not to the LLC.

At Exentax we cover those five fronts every year alongside the US federal calendar (Form 5472, pro-forma 1120, FBAR, state Annual Report and BOI Report when applicable). The goal is that no inquiry finds a loose end and that the structure withstands a 5-to-7-year retroactive review.
