Change of business address

If you want to change the physical or mailing address of your business, you or your representative have to notify the Canada Revenue Agency (CRA) as soon as possible.


Business owners can use the "Manage address" service in My Business Account to change the mailing, physical, and books and records address of their business.

Authorized representatives can use Represent a Client to make address changes on behalf of the owner. This requires level 2 authorization. Representatives with a level 1 authorization only have access to the "View address" service.

By telephone

Call 1-800-959-5525.

For information on who can change the address of your business, go to Authorize a representative for your business.

By mail or by fax

Send your request by mail or by fax to your tax centre. Include the following information:

  • your signature
  • your business name
  • your business number (BN)
  • your old address
  • your new address
  • the effective date of the change
  • the CRA program accounts that need to be updated with the new address (or indicate if all accounts should be updated)

Some businesses have more than one address. Please indicate if this change applies to all addresses currently on file, or only to the old address provided.

Types of 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 RR numbers or 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.
