BOI Filing Updates 2025: Essential Guide for CPA Firms

BOI Filing Updates 2025: What Changed and What Your Clients Owe Now

BOI filing updates in 2025 fundamentally changed which of your clients have active reporting obligations under the Corporate Transparency Act (CTA). At BusAcTa Advisors, we've been tracking these changes closely for the CPA firms we support, because the March 2025 interim final rule created a clean split: US-formed entities are now fully exempt, while foreign entities registered to do business in the US still have live obligations.

If you've been fielding client questions about whether they still need to file, this guide gives you the definitive current picture and the three practical steps your firm should take now.

This is general information, not legal advice. Consult a qualified attorney or compliance professional about your clients' specific obligations under the CTA.

The Current Status: Domestic Entities Are Out, Foreign Entities Are In

On March 26, 2025, FinCEN published an interim final rule that redrew the entire BOI reporting landscape. The rule revised the definition of "reporting company" under the CTA to cover only entities formed under the law of a foreign country that have registered to do business in any US state or tribal jurisdiction. Every entity created in the United States, including corporations, LLCs, and other structures filed with a US secretary of state, is now formally exempt.

That means the vast majority of your domestic clients, sole-owner LLCs, S-corps, closely held corporations, all of them, no longer have any BOI filing obligation. The question "does my client need to file?" now has a straightforward first screen: was the entity formed under US law? If yes, it's exempt. Done.

The rule is confirmed on the FinCEN BOI page, which carries an updated alert reflecting the March 26 effective date.

How We Got Here: The 2024 to 2025 Timeline

The road to the current status was anything but direct. Here's the sequence your clients were living through:

• January 1, 2024: CTA took effect. Most existing entities had until January 1, 2025 to file initial BOI reports.

• December 3, 2024: A Texas federal district court in Texas Top Cop Shop v. McHenry issued a nationwide injunction, blocking the CTA entirely.

• December 23, 2024: The Fifth Circuit stayed the injunction. CTA reporting obligations came back.

• December 26, 2024: The Fifth Circuit merits panel reversed that stay. Injunction reinstated.

• January 23, 2025: The US Supreme Court stayed the Texas Top Cop Shop injunction. CTA technically back in effect again.

• January 24, 2025: FinCEN confirmed no filing required due to a separate injunction still in effect in Smith v. US Department of the Treasury.

• February 18, 2025: The Smith injunction was lifted. FinCEN set a new deadline of March 21, 2025 for most companies.

• March 21, 2025: FinCEN issued an interim final rule exempting all domestic entities and US persons from BOI reporting.

• March 26, 2025: The interim final rule was published in the Federal Register and took effect.

Every client who filed before March 26 because they believed they were required to is now technically an exempt entity. That orphaned data situation is an open question; FinCEN's director indicated in Congressional testimony in September 2025 that plans to delete it were under discussion, but no firm timeline has been given.

What "Foreign Reporting Company" Means Now

For the clients who still have live obligations, precision matters. A foreign reporting company under the March 2025 rule is an entity that meets both of these conditions:

• It was formed under the law of a foreign country (not incorporated or organized in any US state or territory), and

• It registered to do business in a US state or tribal jurisdiction by filing a document with a secretary of state or similar office.

Who fits this? Primarily foreign corporations, foreign LLCs, and other foreign-formed entities that have registered as a foreign entity to operate in states like Delaware, New York, California, or Texas. Think foreign-owned operating subsidiaries, foreign parent companies with US branch registrations, and similar structures your firm may handle as part of international client work.

There's an important carve-out even for these entities: they don't need to report US persons as beneficial owners, and US persons aren't required to provide their information to a foreign reporting company for which they are a beneficial owner. So a foreign entity with a mix of US and foreign owners reports the foreign owners' information only.

The filing deadlines currently in effect are: foreign entities registered before March 26, 2025 had until April 25, 2025 to file. Foreign entities registering on or after March 26, 2025 have 30 calendar days from the date their registration is confirmed as effective. Details are on the FinCEN press release page.

3 Things CPA Firms Should Do Right Now

Given where the rules stand, here's the practical checklist for your firm:

1. Audit your client list for foreign-formed entities

Pull a list of any clients with foreign parent entities, foreign-formed subsidiaries, or structures that include entities incorporated outside the US. These are the ones that still have live BOI obligations. For domestic-only clients, you can close out any BOI-related open items.

2. Verify filing status for foreign entities registered before March 26, 2025

For any foreign reporting companies in your client base, confirm whether an initial BOI report was filed by April 25, 2025. If it wasn't, the filing obligation still exists. FinCEN's BOI e-Filing portal remains operational for these submissions.

3. Monitor for the final rule

FinCEN stated in December 2025 that its progress on a final rule has been delayed by various factors, including a lapse in appropriations. The interim final rule remains in effect for now, but the final rule could modify exemptions, deadlines, or definitions. Any firm with foreign-entity clients should have a monitoring process in place.

The Eleventh Circuit also declared the CTA constitutional in a December 2025 ruling, meaning legal challenges to the law itself are unlikely to eliminate it entirely. The current relief for domestic entities came from regulatory action, not from the courts, and it can be revised by future rulemaking.

One More Layer: State-Level Considerations

The federal BOI exemption for domestic entities doesn't automatically cover state-level disclosure requirements. Several states have their own beneficial ownership or disclosure rules that operate independently of the CTA. New York, California, and a handful of others have laws that may require entity-level ownership disclosure in specific contexts. These aren't BOI reports filed with FinCEN, but they're worth flagging for clients who ask a broad question about disclosure obligations.

This is exactly the kind of multi-layer compliance question where your clients expect their CPA firm to be ahead of them.

The Bottom Line for Your Firm

For most CPA firms, the practical impact of the 2025 BOI changes is simple: domestic clients have no BOI obligation. The compliance headache that loomed over January 2025 is, for those clients, resolved. But the rule isn't finished. The final rule is still forthcoming, and firms serving foreign-owned entities, international structures, or clients with foreign-formed subsidiaries need a current process for tracking what's owed and when.

This is general information, not legal or compliance advice. The CTA and its implementing regulations continue to evolve; confirm current requirements at fincen.gov or with a qualified compliance professional before advising clients on specific filing obligations.
