Updated Checked by the Tax-Services.ca editorial team How we check
Canada has no “enrolled agent”. That’s a US title, given by the IRS, and no CRA page we read uses it. What you can do in Canada is name any person you trust as your representative, and the CRA will then deal with them on your account.
Who can act for you instead of an enrolled agent?
Whoever you authorize. An accountant, a bookkeeper, a tax preparer, a lawyer, or a family member. The CRA doesn’t ask you to pick from a list of enrolled agents. It asks you to give permission, and it offers three ways to do that.
| Way to authorize | How it works | Speed, per the CRA |
|---|---|---|
| My Account or My Business Account | You sign in and add the representative yourself | Fastest |
| Represent a Client | The representative, who needs a RepID, sends a request and you confirm or deny it in your account | Second fastest |
| Form AUT-01 | You sign and mail it, and the representative gets access by phone, mail, fax and in person | Slowest |
The paper form gives offline access only. It doesn’t give the person online access through Represent a Client. You need a separate form for each representative, and it has to reach the CRA within six months of the date you sign it.
Whoever signs in on your behalf has to use the Represent a Client service rather than your own login, a rule the CRA repeats on its sign-in page.
Is a representative the same as a tax preparer?
No, and people mix them up. A representative deals with the CRA about your account, often after the fact, when a letter arrives or a notice of assessment shows a balance owing and someone has to phone. A preparer fills in and files your return. Many people do both jobs, but they’re two different permissions.
For filing, the CRA has a directory of preparers certified to send returns with EFILE. It lists firms, discounters and individuals. Before they submit, you review Form T183 and sign Part F. Keep that form and your slips and receipts for at least six years, says the CRA.
Take Sam in Calgary. His brother-in-law does his return every spring, and last fall a CRA letter asked about a rental slip. Sam’s brother-in-law couldn’t answer the phone for him, because nobody had ever authorized him as a representative. A five-minute online request would have fixed that. Our guide to dealing with the CRA covers what to do when a letter lands.
What should you ask before you hire someone?
Skip the credentials game. Titles differ by country and province, and even a fancy one tells you very little about how careful someone will be with your return, so ask the plain questions instead.
Can I see the return before it’s filed? Will I get a copy and the notice of assessment? What happens if the CRA writes to me next year, and is that in the price? How’s the fee worked out? Fees aren’t set anywhere official, so get the number in writing for your own return. Our page on choosing a tax preparer has a fuller list.
And ask what they can’t do. Nobody can tell you your refund before they’ve seen your slips.
A quick check on what you’ll owe
You can test a preparer’s answer yourself in five minutes. Take an Ontario employee with $50,000 of employment income and $6,000 of tax already withheld. The tax refund calculator shows tax for the year of $6,273.31 and a balance owing of $273.31. Credits it doesn’t include could move that, so treat it as a first pass, not a promise.
If someone quotes you a big refund on a plain T4 return with no other claims, that’s the moment to ask where it comes from. The income tax calculator and the tax credits calculator (federal credits only) give you numbers to compare. If you’re self-employed, add the self-employed tax calculator, which leaves EI out.
Mistakes to avoid
Handing over your CRA sign-in details is the big one, and it’s also the one the whole authorization system exists to make unnecessary, because you can give someone access to your file without ever giving them your password. Second, signing the T183 without reading the return. It’s your signature on it. Third, forgetting to cancel a representative you no longer use, which you can do through the CRA.
A fourth is picking the wrong level of access. Offline access only is plenty for a helper who just needs to phone the CRA about a letter. Keep the wider online level for someone you’ve worked with for years.
How does a US enrolled agent compare with a Canadian CPA or tax accountant?
An enrolled agent is a US federal credential. The IRS says a candidate needs a preparer tax identification number, passing scores on all three parts of the Special Enrollment Examination within three years, an application on Form 23 and a suitability check that covers tax compliance. The credential is about practising before the Internal Revenue Service, so it carries no weight with the CRA.
The CRA does not ask whether your tax accountant, CPA or preparer holds any particular title. It asks for your authorization through My Account, Represent a Client or Form AUT-01, as the table above shows. If your situation touches both countries, ask any adviser whether they handle US returns as well as Canadian ones, and get the answer in writing.
Our sources
The authorization methods and the six-month rule for Form AUT-01 come from the Canada Revenue Agency‘s page on authorizing a representative. Preparer certification, Form T183 and the six-year records rule are from the CRA page on using a professional tax preparer. The enrolled agent requirements are from the IRS page on becoming an enrolled agent. Tax figures are from our calculators, which use 2026 rates.
