What Post Goes to Your Registered Office, and Why It Matters
The CRO, Revenue and people suing the company can all send post to its registered office, and documents left there count as delivered to the company. The urgent ones are CRO strike-off warnings, Revenue assessments and court documents, which often have deadlines of days or weeks.
Letters that need action quickly
- CRO strike-off warnings. If an annual return is late, the CRO can start involuntary strike-off, writing to the registered office first. A struck-off company's assets pass to the State, and restoring it costs far more than filing on time.
- Revenue notices. Assessments, audit notifications and requests for returns can have short deadlines.
- Court and legal documents. Proceedings can be validly served at the registered office, so a missed claim can lead to a judgment being entered against the company.

When legal documents count as served
Legal documents may be validly served on a company at its registered office under the applicable rules, even if nobody has opened or read them yet. That's why urgent post needs to be read promptly.
Routine post
Confirmations of filings, general Revenue correspondence and statements from banks or service providers that use the registered office. Useful to keep, but rarely urgent.
If the CRO has your old address
Until a change of registered office is registered with the CRO, documents sent to the old address recorded there still count as delivered. That's why a move should be followed by a Form B2 straight away.
