Updated Checked by the Tax-Services.ca editorial team How we check
Do you need tax pros at all? For a return with one or two T4 slips and standard credits, probably not. For self-employment income, a rental, a sale of shares or a death in the family, a professional often pays for themselves.
When can you skip tax pros?
If your income is a salary and a bit of interest, filing software or a free clinic covers you. The CRA runs the Community Volunteer Income Tax Program, where volunteers prepare returns for people with a modest income and a simple tax situation. We haven’t listed the income limits because the CRA’s pages give different figures, so check its eligibility page.
Before deciding, put your numbers through the income tax calculator. If the result matches your last assessment and nothing odd is on the return, you’ve learned something useful: this year is routine.
Which situations call for a professional?
Look at this table. If a row describes you, the cost of getting it wrong is usually higher than the cost of help.
| Your situation | Why it gets tricky | Tool to try first |
|---|---|---|
| Self-employed | Expenses, CPP on both halves, instalments | Self-employed tax |
| Rental property | Income and expense split, ownership share | Rental income tax |
| Sold shares or property | Working out the gain and what’s taxed | Capital gains tax |
| Dividends from a corporation | Gross-up and credits | Dividend tax |
| Moved provinces or countries | Residency on December 31 decides the province | Tax credits |
The capital gains tool assumes a 50 per cent inclusion rate. The plan to raise it to two-thirds was cancelled by the Prime Minister’s release of March 21, 2025. Yet the 2026 rate itself isn’t printed on a CRA page we could find, so treat 50 per cent as our working figure.
How do you check a tax preparer?
Ask three plain things. Will you sign the return as preparer? Do you file it electronically through the CRA’s EFILE service? Will I get a copy of everything? The CRA says certified preparers file through EFILE, and you must sign Form T183 first. It also offers a postal code search for EFILE providers.
Don’t sign anything blank, and keep your CRA password to yourself, because anyone acting for you is supposed to come in through Represent a Client with the access level you picked. Level 1 lets them look. Level 2 lets them ask the CRA to change income, deductions or credits, though not your address, name, marital status or bank details.
Beware anyone who promises a bigger refund before seeing your slips. That’s a guess, not a service. Our own tax refund calculator gives a starting figure once you enter real numbers, so you can tell whether a promise is even plausible.
What should you bring to the meeting?
The CRA suggests gathering your income and expense records first, meaning slips and receipts. Update your details in your CRA account too, since a preparer will need your address and marital status to be right.
After filing, you keep the slips, receipts and your copy of the T183 for at least 6 years. Electronic filing usually brings the notice of assessment and any refund within 2 weeks, says the CRA, so expect it soon and check that it matches what your preparer told you. If it doesn’t, ask why.
What can we not tell you?
We couldn’t confirm what tax pros charge, so this page gives no fee levels. Prices vary by task, and you should get a figure in writing before work starts. We also make no claim about any firm’s quality. The tests above cost you nothing and work on any preparer.
Where the information comes from
The preparer, EFILE, T183, Represent a Client and record keeping points come from the Canada Revenue Agency’s pages. Clinic details come from the CRA’s Community Volunteer Income Tax Program page. Calculator figures use 2026 rates held in this site’s tools.
