CAC's deadline to change your company's registered address

CAC's registered address change deadline: why a PO box will not work, and what can block the filing before you even pay.

2 min readBy the Docufy editorial team

Quick answer

File a change of registered address with CAC within 14 days of the change. A PO box or private mailbag is not accepted, and showing the new address in your annual return does not satisfy this duty on its own.

Moving office is often the last thing on a founder's mind once the boxes are unpacked. CAC still expects to hear about it, and fairly quickly.

The filing deadline once you move

A company must notify CAC of a change to its registered address within 14 days of the change. The clock starts on the date of the actual move, not when the decision to move was made.

This is a short window. A company that moves at the end of a busy month can easily let the deadline slip while dealing with everything else a relocation brings.

Why a PO box or mailbag will not work

CAC does not accept a PO box or a private mailbag as a registered office. The address on file has to be a physical location.

This can trip up small businesses, especially ones that started out using a mailbox service for correspondence. Check your registered address against this rule even if you have not moved recently, since an old filing may already have this problem.

The annual return alone does not update this

Some founders assume that listing the new address on the next annual return is enough. It is not.

The law treats the annual return and the address-change notice as two separate duties. Filing one does not excuse the other, even though both end up showing the same address eventually.

If your company has moved and only the annual return reflects it, the address-change filing is still outstanding, and still measured against its own deadline.

The prerequisite that can hold up the filing

Up-to-date annual returns and PSC information before CAC processes most post-incorporation filings, and an address change is no exception.

A company with unpaid annual-return penalties, or with significant-control information that has gone stale, can find this filing stuck before it even reaches payment. PSC disclosures when you register a company explains what CAC expects to stay current on that second point.

Check your annual return status before you start the address change. Clearing an old penalty first is faster than discovering the block halfway through a filing.

Keeping proof of the new address on file

Keep a copy of the lease, utility bill, or tenancy agreement that shows the new address and the date you took it on. This is useful if a bank or CAC ever questions when the move actually happened.

Update your address with your bank and any regulator you deal with once CAC's filing is done, rather than assuming one update covers all of them.

You can start a CAC company registration if you have not yet registered, and the CAC registration hub links the rest of this series for a company already on the register.

Questions people ask

How soon must a company tell CAC it has moved?

Within 14 days of the change, counted from the date of the move, not the date the lease started or ended.

Can a company use a PO box as its registered address?

No. A PO box or private mailbag does not count as a registered office under CAMA.

Does listing the new address in the annual return count as notifying CAC?

No. The law is explicit that showing the new address in an annual return does not satisfy the separate duty to notify CAC of the change.

Why might CAC block the address change filing itself?

Up-to-date annual returns and PSC information first, before it will look at the address change at all. Outstanding annual returns are a common reason.
