Updated Checked by the Tax-Services.ca editorial team How we check
H&R Block Canada is one of several ways to get a return filed, and we’re assuming that’s the “Hrblock” you searched for. The CRA says a tax preparer can be a firm, an organization, a discounter or another certified individual, so the real question is which route fits your return.
Is H&R Block Canada your only option for filing help?
No. You can use certified software, hire a preparer, or send paper, and each has its own trade-offs. We can’t tell you what any firm charges, because we couldn’t confirm fees, offers or refund guarantees for H&R Block or anyone else, so this page makes no claim about them.
What we can lay out is how the choices differ.
| Route | Who sends the return | What to check |
|---|---|---|
| Certified tax software | You | That the product is on the CRA’s certified list for the year |
| Preparer using EFILE | The preparer, with your signed authorization | That they’re certified and listed in the CRA’s preparer directory |
| Discounter | The discounter | What you give up in exchange for an up-front payment |
| Paper return | You, by mail | That you mail it to the right CRA tax centre |
One point from the CRA’s software page is worth knowing. Companies whose products are certified for NETFILE are not representatives of the CRA, and certification covers technical standards only. It says nothing about their prices or how they treat your data.
What should you ask before you hand over your slips?
Start with the fee, and get it in writing before the work begins. Ask whether it changes with the size of your refund. Ask what happens if the CRA reassesses the return later, and whether the preparer will help with that.
Then look at the form. When a preparer files for you, you authorize it by signing Part F of Form T183. Read the whole form first. It’s your return, and your signature says the information is right.
If the offer is a refund paid up front, you’re dealing with a discounter. They work out your expected refund and pay you once, before filing. That’s convenient. It also means they keep something for the service, and we couldn’t confirm what is normal, so ask for the exact amount in dollars.
Finally, ask for a full copy of the return, because you’ll want it when the notice of assessment arrives and again the day you apply for something that checks your income. Simple.
Where does a refund actually come from?
From tax you’ve already paid. A preparer can find credits and deductions you’d missed, but no one can create a refund out of nothing. It helps to know the arithmetic before you sit down.
Take an Ontario employee with $75,000 of employment income. The tax refund calculator puts their income tax for the year at $12,704.65. If their employer withheld $14,000, the refund is $1,295.35. If only $10,000 was withheld, they owe $2,704.65 instead.
So a refund is mostly a sign of how much was taken from each paycheque. It isn’t a prize. When someone promises you a large one before seeing your slips, that’s a reason to be careful.
Real deductions do move the number. Put $10,000 into an RRSP on $90,000 of taxable income in Ontario and the RRSP calculator shows $2,965 less tax. And to see what a full return looks like for you, try the income tax calculator before you talk to anyone. For credits, the tax credits calculator covers the federal ones only.
What mistakes and limits should you watch for?
Leaving out a slip is the easy one to make. Gather every T4, T5 and receipt before the appointment, because a preparer can only work with what you bring, and a return is only as complete as the paper behind it.
Another one is treating the preparer as the person who owes the tax. You do, whoever pressed the button.
Our calculators are estimates. They use the basic personal amount, the employment amount and CPP and EI credits, and they leave out many claims. A preparer who sees your whole year can beat the estimate, and one who doesn’t can miss it.
Where the numbers come from
The preparer, EFILE, Form T183 and discounter points come from the Canada Revenue Agency’s page on using a tax preparer. The remarks on certified software come from its page on finding certified tax software. Both were read in 2026. The dollar examples come from this site’s calculators, which use the 2026 Ontario and federal rates.
Frequently asked questions
What is a discounter?
A firm that works out your expected refund and pays you once, before it files your return. The CRA describes the arrangement on its tax preparer page. Ask for the exact dollar amount the firm keeps.
Does the CRA endorse tax software or preparers?
No. Its software page says firms with NETFILE-certified products are not representatives of the CRA, and certification covers technical standards only.
What do I sign when a preparer files for me?
Part F of Form T183, which authorizes electronic filing. Read the whole form before you sign.
Can a preparer get me a bigger refund?
They can find credits and deductions you missed. The refund still comes from tax already withheld or paid, so it can't exceed what you overpaid.
What are the fees?
We couldn't confirm fees for H&R Block or any other firm. Ask for the amount in writing before the work begins.
