For both individual taxpayers and small business owners, there are numerous benefits to registering:
Access to Tax Information and History
Registering for My Business Account with both CRA and Revenu Québec (RQ) gives you access to:
-
Payroll deductions at source (DAS) paid
-
T4 summaries and slips
-
GST/HST and QST returns filed
-
Payments made and instalments
-
Corporate tax accounts and balances
-
Non-resident accounts
-
And much more
Centralized Access to Tax Documents
Review all tax documents, including notices of assessment, in one place — no more saving, scanning, or losing critical files when you need them most.
Stay on Top of Your Tax Obligations
Keep track of filing and payment deadlines to avoid penalties, reduce interest charges, and prevent issues with information requests or audits due to missed or overlooked mail.
Submit Documents Online
Submit supporting documents for open cases, queries, or authorizations online instead of faxing or mailing them.
Note: CRA still uses fax for most correspondence, while RQ allows secure document uploads. This is usually arranged with a specific representative.
Reconcile Payments More Easily
Access statements of account to reconcile payments between various tax accounts. For example, GST/HST or QST refunds may be applied to payroll or corporate tax balances so being able to view and track this helps simplify reconciliation.
Access to Key Year-End Balances
View year-end balances such as:
-
Capital and non-capital losses
-
Refundable dividend tax on hand (RDTOH)
-
Capital dividend account (CDA) balances
Once verified, these are accessible through your CRA business account.
Share Access with Your Accountant
Use CRA’s “Represent a Client” to authorize your accountant to access tax documents, reconcile balances, and retrieve notices directly.
File and Pay Sales Tax Online
-
GST/QST returns can be filed using Revenue Quebec’s portal, which generates a payment code for online banking payments (look for “Revenue Quebec download code” in your bank’s tax payment section).
-
CRA allows online GST/HST filing and payments, which is especially helpful when expecting a refund.
File Year-End Salary Declarations Online
File T4, RL-1 slips, and summaries online which can be easier than filling out forms by hand and mailing them in.
Access and Manage RQ Payments and Obligations
RQ provides payment codes for GST, QST, and corporate taxes. These can be retrieved from your business account.
Note: Make sure to use the “My Business Account” link, as RQ has several different login types.
Update Your Quebec Business Registration
Once registered in Quebec, access the Registraire des entreprises through Clic Séqur Entreprise. You can update addresses, file your annual declaration, and view business details.
How to Register for My Business Account
Online registration is relatively straightforward.
CRA Registration
-
Identity verification can often be done through a banking partner listed on the CRA registration page.
-
Have your notices of assessment on hand.
-
CRA will either mail you a security code or allow you to retrieve it by phone.
-
Go to the CRA login page and click Register under My Business Account.
Revenu Québec (RQ) Registration
-
Access My Account for Business on the RQ site and follow the instructions to register.
-
You’ll be given a username and password — it’s essential to save these immediately (copy and paste or download), as recovering them requires calling RQ, which can be time-consuming.
-
RQ may also call you directly to verify your identity.
Why It Matters
Registration may take a bit of time, but it gives you significantly more control over your tax obligations — a major source of stress for many business owners and their accountants.
