Updated Checked by the Tax-Services.ca editorial team How we check
A good tax preparer is one the CRA has approved to file returns electronically, who shows you the return before it goes in and gives you proof it was filed. Storefront chains, accounting firms and freelancers can all meet that bar, and any of them can miss it. Names like Liberty Tax are one kind of option, and this page makes no claim about any particular firm. This page is about the checks you make at the desk before you sign. If you’re still choosing between preparers, our guide on how to choose a tax preparer in Canada covers that stage.
How do you check a tax preparer is legitimate?
Start with the CRA’s directory of certified electronic filers, which you can search by postal code. The CRA’s page on using a professional tax preparer says the preparers listed in the directory are certified to file through the CRA’s EFILE service. It takes two minutes, and it’s the step people skip because the shop looks real and the sign is professional and the waiting room is full.
Pop-up offices that show up at tax time in February and vanish by May are the worry here. Treat a refund number quoted before anyone has seen your slips as a sales line. A preparer can’t know your refund until they know your income and your claims.
What should you see before you sign?
The return itself, and Form T183. On that form you sign the declaration and authorization (Part F) that lets the preparer send your return electronically. The CRA’s page says the information on the T183 has to match what’s in your electronic return, so read both. It’s your name and your signature on the declaration.
Ask for a copy of everything, and for proof of filing, which is the notice of assessment. The same page says the notice and any refund are usually processed within two weeks. If a month goes by and you’ve seen nothing, log in to your CRA account and look.
| Ask | Good answer | Worry if |
|---|---|---|
| Are you certified to file electronically? | Yes, and I’m in the CRA directory | Vague or annoyed |
| How is your fee worked out? | Stated in advance, in writing | Taken from your refund and not explained |
| Can I review the return first? | Yes, and I’ll explain each claim | Sign now, read later |
| Will I get proof of filing? | Yes, a notice of assessment | No paperwork |
What does a ten-minute check at the desk look like?
Take Amrit, who’s dropping off her return at a strip-mall office in Surrey. Before she signs anything, she checks that her name, SIN and address on the return are right, because a typo there delays everything. She compares each slip she brought, T4, T5 and receipts, against the lines on the return. She asks the preparer to point to every deduction and say in one sentence why it applies. Then she reads the T183, signs Part F only once the numbers match, and asks for her copy and her originals back before she leaves. None of it is hard. It just takes ten unhurried minutes that most people don’t take.
What is the real cost of a tax preparer?
We can’t tell you. We looked, and found no fee levels we could confirm on an official page, so we won’t quote any. What we can say is how to compare. Get the price in writing for your own return, since a simple T4 return and a return with rental income or a business aren’t the same job. Ask what happens if the CRA reviews the return later, and whether that’s included.
Some preparers, called discounters on the CRA’s page, work out your expected refund and pay it to you up front before filing. Ask what that arrangement costs before you agree to it, because we couldn’t confirm any terms.
Do you even need one for your return?
Often not, especially when your income is one T4 and a few standard credits, which describes a lot of returns. Say you earn $60,000 in Ontario from one job and had $9,500 withheld. The tax refund calculator gives about $1,180 back, based on income tax alone. If a preparer quotes $3,000, ask what they found that the basics don’t show. There could be an answer, such as a deduction you missed, and the tax credits calculator and the income tax calculator help you see how much that might be.
Self-employment, rental income or a sale of investments raises the stakes, and that’s when paying for help earns its keep. For a rough idea of the tax bill, try the self-employed tax calculator before you book.
What mistakes cost people the most?
Handing over originals and not getting them back. Signing a blank form. Letting someone else redirect your refund to their own account without noticing. And believing a mistake is the preparer’s problem alone.
It isn’t. You keep receipts and papers for at least six years, and if the CRA selects your return for review, the request comes to you. The CRA’s page also tells you to keep the completed T183 for that long.
What if something looks wrong after you’ve filed?
Check your CRA account for the notice of assessment and compare its numbers to your copy of the return. If the refund didn’t arrive where you expected, or a claim you never discussed shows up, raise it with the preparer in writing first so there’s a record, and keep your copies. A review of your return is not proof you picked a bad preparer, and a clean one isn’t proof you picked a good one. Your own paper trail is what protects you either way.
Where this information comes from
Guidance on preparers, Form T183, the certified filer directory, the two-week processing time and the six-year record period comes from the Canada Revenue Agency‘s page on using a professional tax preparer. The refund example uses our 2026 federal and Ontario tables and ignores credits you might qualify for. We’re an independent site with no link to the CRA.
