These Regulations require every corporate or other legal entity incorporated in the State to obtain, retain and maintain adequate, accurate and current beneficial ownership information: name, date of birth, nationality, residential address, nature and extent of interest or control and, where issued, PPS number. Entities must keep a local beneficial ownership register and (subject to limited exemptions) deliver information to a Central Register maintained by a Registrar; PPS numbers are not disclosed and only a non‑reversible hashed version may be stored.

The instrument prescribes filing timelines, duties to update registers and to answer notices, provisions for presenters and designated persons, mechanisms to report and resolve discrepancies, and differentiated access (extensive for law enforcement and competent authorities; restricted public and designated‑person access). Non‑compliance attracts criminal and civil sanctions including summary fines, potential imprisonment and indictable fines up to €500,000.
