Change a business address

To better protect businesses, some users may be notified that they have been selected to provide the CRA additional information for these types of requests.

Notify the Canada Revenue Agency (CRA) as soon as possible of changes in any of your business addresses.

Different types of business addresses

Physical address: The physical address is the business or head office address. This address must be where the day-to-day activities take place.

It must represent the physical location of your actual business. You cannot use such things as rural route (RR) numbers or post office (PO) boxes as a business address. If a street address is not available, use the legal description of the location of the business. For example, Lot 1, Concession 2.

Mailing address: The mailing address can be different from the physical address. For example, you could have your business mail delivered to your home or your accountant.

Books and records address: If your business books and records are at a location different from your physical address, you must provide this information to the CRA.

Different mailing addresses for each of your registered business accounts: If you have different mailing addresses for your registered business accounts, you or your representative must notify us of the change of address.
