Fifteen Fun Acronyms & Terms


The world of US tax and disclosure compliance is filled with a mess of acronyms and initialisms; here is a short glossary to help find your way.


1. FBAR (Foreign Bank Account Report)

The FBAR, also known as FinCEN Form 114, is a report filed with the Financial Crimes Enforcement Network (FinCEN) of the U.S. Department of the Treasury to disclose foreign financial accounts.


2. FinCEN (Financial Crimes Enforcement Network)

The Financial Crimes Enforcement Network, responsible for collecting and maintaining information on financial transactions to combat money laundering and other financial crimes. FinCEN is a division of the US Department of Treasury but is separate from the IRS.


3. IRS (Internal Revenue Service)

Fun fact, IRS does not stand for “Incredibly Rapid Service”.  As you are likely aware, it stands for the Internal Revenue Service; the federal revenue agency of the United States and a division of the US Department of Treasury.


4. CTA (Corporate Transparency Act)

Corporate Transparency Act; a new US law requiring the disclosure of beneficial owners of certain US and foreign entities.


5. UBO (Ultimate Beneficial Owner)

Ultimate Beneficial Owner, an industry term referring to the individual who, based on the applicable paradigm, is determined to own an asset or entity. Generally, UBO status is determined on either who derives the economic benefits of the property, or who controls the property, or both factors.

Different jurisdictions have their own criteria for determining the UBO. The CTA does not use the term UBO, therefore we generally will use the capitalized term Beneficial Owner when referring to a UBO in the context of the CTA.


6. USP (US Person)

A US Person, but this doesn’t have to be an individual; it may refer to an individual, corporation, partnership, or other entity subject to U.S. jurisdiction and required to comply with U.S. tax and reporting requirements.
