The Canada Revenue Agency (CRA) understands that many businesses continue to change in response to new economic challenges and opportunities. As you undergo business changes, you may face different requirements in managing your tax affairs, and we are here to help, year-round, with your unique business needs.

When your business is going through changes, visit the Changes to your business and Canada Revenue Agency program accounts page to find the information you need for your next steps. You can easily make some changes online through My Business Account.

Here are some updates you can make online:

Authorize a representative
Change a business address

• Manage notification preferences to add or change an email

Save time when updating your business information by registering for My Business Account.

Getting back to business

If you find yourself in a situation where you have closed your business and are now resuming operations, depending on your situation, you may need to contact us:

When you decide to re-open a business account, including a payroll or GST/HST account, and the legal entity has not changed – just call us at 1-800-959-5525 (note that you may be asked to provide additional information to confirm your identity).
If the legal entity type has changed – we consider your business to be a new business and you will need to register for a new business number and new program accounts.
If you dissolved a corporation and would like to re-open a Corporate Income Tax account – you must send articles of revival to your tax centre. To find your office, go to Tax services office and tax centres. Reviving a corporation is not a change in the legal entity.

Other changes the CRA needs to know about

The CRA gets thousands of questions each year from businesses looking for help as they change. Our Changes to your business and Canada Revenue Agency program accounts page will give you information on what the CRA needs in many common situations, such as:

Administrative changes – Among other things, you have to contact the CRA if you want to change your fiscal year-end, the name or address of your business or the business activity you're engaged in. You'll also have to inform the CRA whenever one of the owners, partners or directors of your business changes. Or you can simply contact us to update your phone number and email address.
Growing your business – Information is available on the tax implications of buying a business, opening more branches, locations and divisions, bringing personal assets into your business, adding CRA program accounts to your business number, and more.
Changes to business operations – Find out what the CRA needs if you are looking to temporarily stop business operations or sell your business, close CRA program accounts, file for bankruptcy or enter into receivership, if there has been a retirement or death of business owner or partner, and more.
