Updated Checked by the Tax-Services.ca editorial team How we check
A good tax accountant is one you can check, question and understand. Three things you can test in an afternoon: their standing with the provincial accounting body, whether they’ve filed returns like yours, and whether they’ll write the fee down before starting. Everything else, including the reviews, is a weaker signal.
How do you tell a good tax accountant from a busy one?
Good ones ask you questions first, about your slips, your family, your business and whatever changed this year, and they’ll keep asking until the picture is complete. If someone quotes a price and promises a refund on the phone before seeing a single document, walk away. Nobody can.
You won’t find firm names here, or an average fee. Those two things are what most “near me” pages sell, and neither can be backed from an official source.
What does a good return look like in numbers?
For an Ontario resident with only employment income, 2026 rules, the income tax calculator gives this.
| Employment income | Federal tax | Ontario tax | Total income tax | Average rate |
|---|---|---|---|---|
| $60,000 | $5,338 | $2,982 | $8,321 | 13.9% |
| $85,000 | $10,227 | $5,324 | $15,551 | 18.3% |
| $120,000 | $17,502 | $9,386 | $26,888 | 22.4% |
CPP and EI come on top of those amounts. Now test an accountant with this. Put a $6,000 deduction against the $60,000 income and the tax falls to $6,891, so it saves about $1,430. If a preparer can’t tell you which deductions you’re entitled to, or why they chose the ones they did, treat that as a sign you should keep looking.
Which questions should you ask a tax accountant near you?
Pick the accountant on fit. Location matters less than people think, since federal rules are the same everywhere. A local one can meet you and know local practice. A distant one can be just as good for routine work.
- Which provincial body are you registered with? I’ll check the register.
- How many returns like mine did you do last year?
- What will you charge, what’s extra, and when do I pay?
- If the CRA writes to me, who answers, and is that in the fee?
- Which of my documents do you keep, and for how long?
Write the answers down. A good accountant won’t mind. One who gets vague about the fee or the register has told you what you needed to know.
What does a fifteen-minute first call tell you?
More than a website does. Describe your situation in two sentences, say a T4 job, a side gig and a rental room, and listen to what comes back. A good accountant repeats it in their own words, names one or two things that might matter, such as the instalment rules for side income, and says plainly whether they take that kind of work.
A weak one jumps straight to price, or says “no problem, we do everything”. Hang up politely and try the next name on your list. Three calls will teach you more than three weeks of reading reviews.
Does a designation matter?
A professional designation tells you about their training and the body that can discipline them, and that’s why the register check is on the list. It doesn’t tell you whether they’ve done a return like yours. A designated accountant who does corporate audits all day may be a worse fit for your rental income than a careful preparer who does two hundred personal returns a season. Ask about both the letters and the experience.
What about self-employed and business owners?
You need more from an accountant than a T4 filer does. The 2026 CRA deadlines put self-employed filing on June 15 but the balance owing on April 30, with instalments on March 15, June 15, September 15 and December 15. A good one tells you that before you ask, and sets the instalments with you so the April bill doesn’t land all at once.
Try the self-employed tax calculator before the meeting. On $80,000 of net business income in Ontario it shows $22,126 of income tax and CPP together. The tool leaves out EI and lets deductions cut income tax but not CPP, so take it as a rough guide. If you run a company, the corporate tax calculator gives a starting point for the corporation’s own tax.
What are the warning signs?
- A fee based on the size of your refund.
- Pressure to claim something you can’t document.
- You can’t reach them between February and May.
One more. Anything you don’t understand on the return you’re about to sign.
It’s your return whoever prepares it, and the CRA will write to you, not to them. Ask until you can explain each line back in your own words. At tax time you’re paying for peace of mind as much as arithmetic, so if you don’t feel it, keep shopping.
Sources, and how we checked them
Deadlines come from the Canada Revenue Agency‘s 2026 tax deadlines page, read in September 2026. Tax amounts come from this site’s calculators, using 2026 federal and Ontario data. We aren’t connected to the CRA, any accounting body or any government.
Frequently asked questions
How do I know an accountant is good?
Check the provincial register, ask about returns like yours, and get the fee and scope in writing before you start.
Should a tax accountant charge based on my refund?
That's a warning sign. The result depends on your documents, so a refund can't be promised in advance.
Does my accountant need to be local?
No. Federal rules are the same everywhere, though a local firm can meet in person.
When is the 2026 self-employed tax balance due?
April 30, 2026. The return itself is due June 15, 2026.
What does a good tax accountant cost?
We couldn't confirm a typical fee. Get a written quote and ask what would add to it.
