Updated Checked by the Tax-Services.ca editorial team How we check
Quality tax preparation in Canada comes down to three checks you can make yourself: the preparer is certified to file electronically with the CRA, you see and understand the return before it goes in, and the result matches a quick estimate of your own. The tax on $60,000 of Ontario employment income, for example, should land near $8,320.50.
Who counts as a quality tax preparer?
If you searched for a firm called Quality Tax, we can’t say anything about it. We haven’t verified any firm’s fees, results or reviews, and this site has no link with any preparer. What we can give you is how to judge one.
Start with certification. The CRA keeps a tax preparer directory of people certified to file returns electronically through EFILE. Firms, organizations, discounters and individuals all appear in it. Being in the directory says they can file. It doesn’t say they’re good. That part is your judgement.
Fee levels aren’t published by the CRA, and we won’t guess at them either. So ask for the price before any work starts, and ask what changes it. Our guide to choosing a tax preparer goes through the same questions in more detail.
What should you see before anything is filed?
The whole return. The CRA says you must review the completed electronic return and Form T183, the information return for electronic filing, before you authorize it. You sign Part F, the declaration and authorization, so you stay responsible for what’s in it.
That has a practical side. If your preparer says “just sign here” and can’t explain the refund or the balance, wait. A quality preparer walks you through the top of the return, your income, deductions and credits, and tells you why each one is there.
| Check | What good looks like |
|---|---|
| Certification | Listed in the CRA tax preparer directory |
| Fee | Stated in writing before work begins |
| Return review | You get the return and Form T183 to read first |
| Signature | You sign Part F only after reviewing |
| Result | Close to your own estimate, gaps explained |
How do you sanity check the result?
Run your own ballpark estimate. With $60,000 of employment income in Ontario, the income tax calculator shows $8,320.50 in federal and Ontario tax. Add a $6,000 RRSP deduction and it falls to $6,890.91, which is $1,429.59 less. Your return will differ if you have other credits, but a gap of thousands calls for a question.
Say Jordan in Windsor gets a return back showing tax of $11,000 on that same $60,000 salary. That’s about $2,700 above the estimate, so it’s worth asking the preparer to point to the line that explains it. Maybe a side income slip turned up. Maybe something was entered twice. You won’t know until you ask.
The tax refund calculator is handy when the number you care about is the refund. The tax credits calculator can show whether a credit you were told about is real, though it covers federal credits only.
What should you have ready for your preparer?
Access. As of 15 July 2025, preparers can no longer request authorization for individual clients through EFILE. They go through the CRA’s Represent a Client service. You can add your preparer in your CRA account, confirm their request there, or give them details from a notice of assessment that’s at least six months old so they can ask securely.
Check, too, that your direct deposit information and mailing address on file are current, as the CRA advises. A refund sent to an old account is a nightmare to chase. Our checklist of documents for your tax return covers the slips and receipts to bring.
What red flags are worth walking away for?
A preparer who won’t give you a copy of the return. One who wants the refund paid to their account. A fee that depends on how big your refund is and that nobody will explain. Also be careful with discounters: the CRA describes them as giving you one up-front payment based on your expected refund. Ask what that costs and what happens if the CRA’s number comes out lower.
Those red flags are our reading of good practice, not CRA rules, so weigh them yourself. The CRA usually processes an electronically filed return and any refund within 2 weeks, which gives you a rough timeline to hold any preparer to.
What should you keep after the return is filed?
A full copy of the return, the signed T183 and the notice of assessment when it arrives. Compare the notice to what you were shown in the office. If a number moved, ask why that day, not months later. Keep your receipts too, since the CRA can ask to see them after the fact, and a good preparer will tell you which ones to hold on to and for how long.
Sources, and how we checked them
The points on the directory, Form T183, Part F, discounters and the two week processing time come from the Canada Revenue Agency page on using a professional tax preparer, read in 2026. The authorization changes of 15 July 2025 are from the CRA’s tax tips. Income tax figures come from our 2026 calculator for Ontario. We didn’t confirm fees, ratings or claims for any named firm.
