Updated Checked by the Tax-Services.ca editorial team How we check
The best tax filing accountant near you is one who is certified to file electronically, will show you the return before it goes in, and gives you a copy afterwards. Distance matters less than those three things. We can’t recommend a firm or quote a fee, because neither can be checked from an official source, so this page is about how to pick one and how to test the work.
What should a tax filing accountant do before filing?
Most returns go in through the CRA’s EFILE service, which only certified preparers can use. Before they send anything, you sign Part F of Form T183, the declaration that lets them file for you. You should also read the return and the T183 first. The CRA says the T183 must match the electronic return exactly, so a mismatch is a reason to stop and ask.
If a preparer files without asking you to sign, walk away. Same if they won’t let you read the return. It’s your name on it.
How do I find a local preparer I can trust?
Start with people you know who have similar income to yours. A friend with rental property will get you further than a friend with one T4. Then ask each candidate the same short list of questions, so the answers compare.
| Ask this | What a good answer sounds like |
|---|---|
| Do you file through EFILE? | Yes, and they explain the T183 |
| Do I get a copy of the return? | Yes, every time, before and after filing |
| Have you done returns like mine? | A specific answer, such as rental income or self-employment |
| How do you charge? | A price or method stated before work starts |
| Who signs the return? | You do, and they sign as preparer |
Fees vary a lot and we haven’t confirmed any figure, so get the price in writing first. Watch for one thing in particular: a big refund promised before anyone has seen your slips. The CRA warns about preparers who promise unusually large refunds or claim things that never happened, such as donations or child care costs.
Do I even need an accountant for my return?
Maybe not. If you have a T4, a few slips and the usual credits, certified tax software can do it. A tax filing accountant earns the fee when the return has moving parts: self-employment, rental income, foreign property, a death in the family or a move between provinces.
Try it yourself first, at least roughly. Enter your pay in the income tax calculator and you’ll see a rough total before anyone touches your file. It’s a decent sanity check on what the preparer later tells you.
What does a good filing appointment look like?
You hand over your slips and last year’s return, and the preparer asks what changed. Did you move, marry, have a baby, start a side job, sell something, work from home? They go through the answers line by line, then show you the draft with the refund or balance at the bottom. You ask about anything odd, and they explain it in plain words.
It should feel like a conversation, not a drop-off. If you’re in and out in five minutes with no questions asked in either direction, you’re probably getting a return that reports only what was on the slips, and nothing you could have claimed.
How can I check the work before it’s filed?
Take a worked case. On $85,000 of employment income in Ontario, the calculator shows $15,551.05 of federal and Ontario income tax, plus $5,769.52 of CPP and EI, leaving $63,679.43. That’s an average tax rate of 18.3%. If your slips show $14,000 already withheld on a somewhat lower income, the tax refund calculator gives a refund of about $1,295.35.
Your preparer’s number won’t match to the dollar, since real returns use credits these tools skip. But a gap of thousands needs an explanation. Ask which line caused it. A good preparer answers in a minute.
If you work for yourself, run the self-employed tax calculator as well. It counts both halves of CPP, though not EI or business expenses, so treat it as a rough guide. To see what deductions and credits could save you, try the tax deductions and credits calculator, which covers federal credits only.
Mistakes that cost people money
The biggest one is assuming the preparer carries the risk. The CRA is clear that you are responsible for the information on your return, even when someone else prepared it. A wrong claim lands on you.
Other slips are smaller but common:
- Handing over slips and never seeing the return.
- Paying cash with no receipt.
- Letting a preparer deposit your refund into an account that isn’t yours.
- Throwing away receipts. The CRA says to keep slips, receipts and the T183 for at least six years.
Self-employed people also mix up dates. Filing is later than April 30, but any tax owing is still due then. That’s a question for the first meeting.
And one for the paycheque crowd: check that the bank details on the return are yours before you sign. A wrong digit sends a refund astray, and fixing it takes weeks.
Where the numbers come from
Procedure and record rules on this page come from the Canada Revenue Agency‘s pages on using a tax preparer and on tax preparer warnings, read in September 2026. The tax examples come from the calculators on this site, which use 2026 federal and Ontario figures. We couldn’t confirm any fee level, so none is given. We’re an independent site, and no government body is behind it.
