This article describes the Corporate Transparency Act as it stood in late 2024. The compliance landscape changed dramatically in the months that followed — first through litigation, then through a regulatory rewrite. For the current state of play, see our March 2025 update. The history below is preserved as written for context.

Congress passed the Corporate Transparency Act (CTA) as part of the National Defense Authorization Act of 2021. The law was designed to combat money laundering, tax fraud, and terrorist financing by requiring most U.S. small businesses to disclose information about their beneficial owners — the individuals who actually own or control the company — to the U.S. Treasury’s Financial Crimes Enforcement Network (FinCEN).

The original implementation timeline put a Dec. 31, 2024 deadline on most existing companies and required new companies to file within 90 days of formation. For business owners, the law represented a significant new compliance obligation — one most clients had never heard of.

Who was covered.

The CTA defined a reporting company broadly: most U.S. corporations, LLCs, and similar entities formed by filing with a state secretary of state, plus foreign entities registered to do business in the U.S. There were 23 enumerated exemptions, mostly for entities already heavily regulated — banks, public companies, registered investment advisers, large operating companies meeting specific employee/revenue thresholds. The exemptions excluded most genuine small businesses from a free pass: if you owned an LLC for your rental property, your consulting practice, or a small operating business, you almost certainly had to file.

What had to be reported.

For each beneficial owner — a person who either owned 25% or more of the company or who exercised substantial control over it — the report required:

  • Full legal name
  • Date of birth
  • Current residential address
  • A unique identifying number from a passport or driver’s license, plus an image of the document

For new companies (formed on or after January 1, 2024), the report also required information about the company applicant — typically the lawyer or filer who actually submitted the formation paperwork.

The original timeline.

  • Companies formed before January 1, 2024: file by December 31, 2024.
  • Companies formed during 2024: file within 90 days of formation.
  • Companies formed on or after January 1, 2025: file within 30 days of formation.
  • Any change in beneficial ownership had to be reported within 30 days.

Penalties.

The CTA carried meaningful teeth. Civil penalties of up to $500 per day for late or false filings, plus criminal penalties of up to $10,000 in fines and 2 years in prison for willful violations. For a small business owner, an inadvertent miss could be expensive.

What we told clients in late 2024.

For our small business clients, the message was straightforward: don’t miss the deadline. The filing itself was free, and FinCEN’s online portal was workable. The harder part was identifying every entity in a client’s structure — the active operating companies, the dormant LLCs, the holding entities, the single-purpose vehicles formed years ago for a specific deal — and confirming whether any exemption applied. We helped clients run that inventory and either file or document the exemption.

What happened next.

The CTA didn’t survive its first deadline cleanly. In December 2024, a federal district court in Texas issued a nationwide preliminary injunction blocking enforcement of the BOI reporting requirement — the start of a months-long whiplash that took compliance through several reversals before the law was effectively rewritten in early 2025. We covered each twist:

The current rule, as of the March 2025 update, exempts U.S. domestic reporting companies from the BOI filing requirement and limits the regime to foreign-formed entities. Reach out if you’re uncertain about your obligations under the current rule.

Quick FAQ.

Did my LLC have to file under the original CTA rule? Probably yes — unless you fit one of the 23 exemptions. The original rule swept in nearly every small-business LLC and corporation.

Did I miss the deadline? The original Dec. 31, 2024 deadline was overtaken by litigation. Companies that didn’t file in late 2024 were not penalized for the missed deadline once the injunction issued, and the subsequent rule change largely moots the original deadline for U.S. domestic companies. Confirm with us if you have any concern.

Do I have to file now? Under the March 2025 interim final rule, most U.S. domestic companies do not. Foreign-formed reporting companies still have obligations. We help clients confirm where they stand.

What if I formed a new LLC after the rule change? If it’s a U.S. domestic entity, current rules generally exempt you. We confirm in writing for our business clients that we’ve reviewed their situation. Talk to our small business team if you’re uncertain.
