Every tax season, a bookkeeper somewhere logs into the CRA website with every intention of filing a client's GST/HST return, only to realize the browser is still sitting in the personal My Account page. It is a small mistake, but it costs time and creates doubt about which portal actually holds the correct information. The difference between CRA My Account vs My Business Account Canada confuses many people, including experienced business owners, because both portals look similar and accept the same sign-in credentials. Understanding which portal you need for which task is the difference between a clean client file and a missed deadline.

If you are new to the personal tax side of CRA, our guide on CRA T1 personal tax returns for self-employed Canadians explains how personal returns work. For now, let's focus on the account structures that shape your CRA work.

What Are CRA My Account and My Business Account?

CRA My Account is the Canada Revenue Agency's online portal for individual taxpayers. It is linked to your Social Insurance Number and gives you access to your personal income tax, benefits, and credits. You can view your notice of assessment, check your RRSP and TFSA contribution room, file a return, request a change of address, and see tax slips such as T4s and RRSP receipts. If you are self-employed as a sole proprietor, you will use My Account for the personal T1 return, but the business revenue and expenses still appear there.

CRA My Business Account is the online portal for registered businesses. It is linked to a business number, not a Social Insurance Number. Through this portal, you can manage your GST/HST account, payroll deduction account, corporate income tax, and other CRA programs tied to that business. You can file returns, submit remittances, view balances, and monitor correspondence. A business number can hold multiple accounts, like GST/HST and payroll, under one identifier.

The easiest way to remember the split is that My Account is for the person, while My Business Account is for the business entity. A sole proprietor might use both, because the business registration is often separate from the personal tax file.

Feature CRA My Account CRA My Business Account
Linked to Social Insurance Number Business Number
Main users Individual taxpayers Business owners, authorized employees
Common services Personal tax returns, benefits, RRSP/TFSA limits, address changes GST/HST returns, payroll remittances, corporate tax, business profiles
Representative access Through Represent a Client Through Represent a Client or an authorized representative
Primary login method CRA user ID and password or sign-in partner Same sign-in options, but you select the business account after login

Key Differences Between My Account and My Business Account

The two portals share a sign-in system, which creates some confusion. When you log in with your CRA credentials, you may see a landing page where you choose My Account or My Business Account, depending on what you need. That does not mean the accounts are the same. They are separate portals with separate security profiles and separate information.

One major difference is how representatives work. For My Account, an individual can authorize a representative to see their personal tax information. For My Business Account, the business owner can add authorized representatives or business administrators. A bookkeeper who works for several clients must access each business through Represent a Client, using their rep ID and an authorization code from each client. This is a deliberate safeguard, but it creates a workflow that firms need to manage.

Another difference is what you cannot do. You cannot use My Account to file a GST/HST return, and you cannot use My Business Account to view your personal benefits or contributions. Trying to use the wrong one almost always leads to a dead end and a phone call. The practical rule is to ask: are you doing something for the person or for the business?

If you are a small business owner, the boundary is not always obvious. You may need to handle a personal notice of assessment and a payroll remittance in the same morning. That is why many Canadian businesses use a small business accounting platform to keep the underlying records clean, while the CRA portals remain the place of record for remittances and filings.

How to Register and Access Each Portal

Registration for My Account usually requires your SIN, date of birth, and a postal code. The CRA asks for specific amounts from your tax return to verify your identity. After that, you create a user ID and password or choose a sign-in partner, which is a participating institution you authorize to identify you. Once inside, you can set up two-factor authentication for extra security.

Registration for My Business Account follows a similar process but asks for your business number. You will enter the business number and a further financial detail, like a specific amount from a prior year's return or a GST/HST assessment. The system validates that you are authorized on the business. You then create your sign-in credentials.

For accountants and bookkeepers, the process is different. You do not register in My Business Account on behalf of clients. Instead, you use CRA's Represent a Client service with your rep ID. Before you can access a particular client, the client must add you, either online in their My Business Account or by filing a paper form such as T1013 or RC59. Once the authorization is approved, you can switch between client accounts under your own rep ID.

If this is your first time dealing with the CRA portals for a client, it is worth revisiting our CRA T1 personal tax return guide for self-employed Canadians to see how personal and business tax obligations interact. The business portal will often reference personal tax information for sole proprietors, so understanding that connection helps avoid surprises.

Common Tasks in Each Portal

My Account is where you want to be when you need to correct a personal address, check benefit eligibility, view a notice of assessment, or file a personal tax return. It is also where you can apply for programs like the Canada Workers Benefit or the GST/HST credit. Many individuals use it at least once a year to check their contribution room for RRSPs and TFSAs.

My Business Account is where you go to file a GST/HST return, make a payroll remittance, and manage the business's corporate tax. You can also view the status of a business number, update business addresses, and authorize employees to act on behalf of the business. If you have multiple businesses, each business number has its own profile within the same My Business Account login.

Consider a contractor firm in Ontario with 12 employees. The owner, Sarah, has a My Account for her personal taxes and a My Business Account for the corporation. Her bookkeeper needs to remit payroll and file the quarterly GST/HST return. The bookkeeper cannot use Sarah's password. Instead, Sarah logs into My Business Account and adds the bookkeeper as an authorized representative, using the bookkeeper's rep ID. The bookkeeper then accesses the business through Represent a Client. This is the only compliant path, and it protects both the owner and the bookkeeper.

For corporations, the T2 filing process adds another layer. If you are deciding between the shorter and longer version, our T2 short form vs long form guide explains the difference. The CRA portal itself will show which form applies to you based on your filings, but knowing the distinction helps when you prepare the return.

Represent a Client: When You Need Access to Client Accounts

Represent a Client is the CRA portal specifically designed for accountants, bookkeepers, and other authorized representatives. It is not the same as My Business Account, though some people confuse them. With a rep ID, you can access any client who has authorized you, and you can toggle between clients without logging in and out repeatedly.

The authorization process requires a valid rep ID and an access code from the client. The client can generate the code from within their My Business Account or from My Account for personal tax matters. Once authorized, you can see the relevant CRA correspondence, file returns, and make changes. The access is role-based, so you only see what the client granted.

This is where many firms feel the friction. Between the CRA authorization, the client's documents, and the accounting software, there is a lot of back and forth. A dedicated practice management platform, like Awditify for accounting firms, can store authorization records and client documents in one place. That way, when you need to verify a CRA deadline or a client's prior remittance, you are not digging through email threads.

Using the Portals Alongside Accounting Software

The CRA portals are authoritative for filings, but they do not do bookkeeping. A GST/HST return filed through My Business Account still needs general ledger classifications behind it. Payroll remittances need to match what you recorded in your payroll ledger. The gap between the portal and the books is where errors happen.

Work through a manual workflow. You download bank statements, code transactions, prepare a GST/HST return based on those codes, and then enter the amounts into the CRA portal. If the codes are wrong, the return is wrong. If a bank feed misses a transaction, the remittance is off, and you spend time chasing a reconciling item. The problem is not the CRA portal; it is the lack of connection between the CRA information and the day-to-day books.

Now compare that to an automated workflow. A bookkeeper uses Awditify's automatic bank feeds to pull transactions directly from the bank. The AI categorizes them into common groups, and you review and approve the categories. The system tracks GST/HST on those transactions so you know your net tax before you ever open the CRA portal. When you are ready to file, the supporting numbers are already in the ledger.

If you use Awditify, the Help Center walks through how to set up your bank accounts and transaction feeds step by step. The same applies to invoicing and accounts receivable, which is useful if you are tracking GST/HST on sales.

Security and Access: What to Watch For

CRA scams are common, and both portals are prime targets. The CRA will never ask for your password, a payment via prepaid credit card, or personal information through an unsolicited email or text. If you receive a suspicious call, hang up and call the CRA's official line. If you log in and see something unfamiliar, report it immediately.

For accountants, never use a client's login credentials. It is tempting when you have the password on file, but it is a security violation and could expose the client's entire business profile. Use Represent a Client and keep your own credentials secure. Many firms now use password managers and two-factor authentication for their rep ID logins.

Inside your business, decide who needs access to My Business Account. CRA allows you to set up authorized representatives at different levels. You can give an accounting employee the ability to file returns without giving them the owner's login. This reduced access is important for job roles where someone handles payroll but should not see the entire corporate file. It also creates a cleaner audit trail for your internal controls.

Frequently Asked Questions

Can I use one login for both CRA My Account and My Business Account?

Yes, you can use the same CRA user ID and password or sign-in partner for both portals. After signing in, you choose which account you want to access. The two portals remain separate, with different linked numbers, different services, and different representative permissions. That means you need to be intentional about which one you open for a given task.

Do I need a separate My Business Account for each business I own?

Each business number has its own profile under My Business Account. When you sign in, you will see the business numbers you are authorized for, and you can switch between them. You do not need to create a new login for each business. However, you need to be properly authorized on each business, which usually requires a validation step with that business's information.

Can my accountant or bookkeeper access my CRA business account on my behalf?

Yes, but they cannot use your password. They must use the CRA's Represent a Client service with their own rep ID and your authorization. You can add them inside My Business Account, and the CRA will approve the authorization. Once approved, they can access your business account electronically, file returns, and view balances.

What is the difference between CRA My Account and Represent a Client?

CRA My Account is for individuals to handle their own personal tax matters. Represent a Client is a separate service for accountants and bookkeepers who need to access other people's accounts. It uses a rep ID instead of a personal login. Both services coexist, and many professionals use Represent a Client for every client rather than managing multiple hard-copy authorizations.

How do I keep my GST/HST and payroll records accurate alongside CRA?

The CRA portal tracks what you remit, but it does not maintain your accounting records. You still need a proper bookkeeping system that records sales, expenses, payroll, and the associated GST/HST. A Canadian accounting platform like Awditify automates much of this by pulling bank feeds, categorizing transactions, and tracking tax codes. The result is that when you log into My Business Account to remit, the figures in your ledger match the numbers you enter.

What to Do Next

Use the right portal for the right job, register properly, and authorize representatives early. For accountants, set up Represent a Client before tax season starts, not when a client is on the phone with CRA. For business owners, keep personal and business files separate, both in the CRA portals and in your accounting software.

If you are tired of the manual back-and-forth between bank statements and CRA filings, Awditify's small business platform handles the bookkeeping side for you. It also supports Canadian payroll and GST/HST tracking, so the numbers you bring to My Business Account are the same ones already in your ledger. Book a demo to see how it fits your workflow.

If CRA reassesses you, you will need to act quickly. Our practical guide to handling a CRA reassessment covers the steps that follow, including deadlines and your right to object. That is a useful next read once your account access is sorted.
