Updated Checked by the Tax-Services.ca editorial team How we check
The right tax solution depends on the problem you have. If you’re not sure what you owe, a calculator gets you a number in a minute. If you have a self-employed income, a corporation or a messy year, you may want a preparer. And if your income is low, a free clinic may do the whole return at no cost. Simple as that.
Match the problem to the fix
Most people search for tax solutions when something feels unclear, not because they need a grand plan. So start by naming the problem. Here’s how the common ones line up.
| Your problem | What usually solves it |
|---|---|
| How much tax will I pay this year? | An income tax calculator |
| Will I get a refund or owe money? | A refund estimate using your slips |
| I’m self-employed and don’t know what to set aside | The self-employed tax calculator, then instalments |
| I own a corporation | A preparer who files T2 returns |
| My income is low and my return is simple | Free tax software or a free clinic |
| I want a smaller bill next year | A look at credits and RRSP room before year end |
Still can’t tell which row is yours? Our short tax situation quiz asks a few plain questions and points you the right way.
Start with a number, not a service
Before you pay anyone, find out roughly what you’re dealing with. Say you earn $60,000 in Ontario from one job. Our calculator shows $8,320.50 in federal and Ontario income tax, and another $4,339.75 goes to CPP and EI. That’s 13.9% of your income in income tax alone.
Now say your employer withheld $9,000 during the year. The tax refund calculator puts the refund at $679.50. Not a windfall. Would you pay a preparer to file a return worth that? Probably not, so software is the obvious fit. Most of us would rather spend a few bucks on a coffee than on a fee bigger than the refund.
When self-employment changes the answer
Here’s where solutions start to matter. Earn $80,000 as an employee in Ontario and the calculator shows $14,127.85 in income tax plus $5,569.52 in CPP and EI. Earn the same $80,000 as a sole proprietor and income tax is $13,233.57 while CPP is $8,892.90, because you pay both halves. The total is $22,126.47.
That gap is what people miss. Nobody withholds anything for you, so the money has to be there when the bill comes. The instalments calculator shows what quarterly payments could look like. One caution: our self-employed tool leaves out EI and GST/HST, and business expenses are yours to work out first.
A simple habit helps more than any product. Every time a client pays you, move a slice into a separate savings account the same day, and treat it as untouchable. Come tax time, the bill is already sitting there.
What about a tax scheme that promises less tax?
Should you try one? Skip it. The CRA has a page warning about tax schemes that promise to reduce your taxes, and it says to stay away from preparers who offer false claims, such as made-up charitable donations. It also says unusually large refunds can point to questionable practices. A real solution uses credits and deductions you are entitled to, backed by receipts.
Mistakes that cost people money
Filing late is the big one, and the CRA links late returns to interest, penalties and interrupted benefit payments such as the GST/HST credit and the Canada child benefit. The payment date for 2025 was April 30, 2026, even for people with the June 15 filing date. If you owed, interest ran from April 30. The CRA’s due dates page lists both dates.
The second mistake is trusting an estimate as if it were a return. Our calculators use the basic personal amount, standard credits and contributions. They leave out benefits, refundable credits and other claims. Treat the result as a starting point and use the tax credits calculator to check the federal ones. It’s federal only, so provincial credits still need checking.
Third, don’t sign a blank form. The CRA says so directly, and it’s good advice for any preparer, human or app.
Who can you ask if you’re still stuck?
Start with the free options: the CRA’s own pages, a volunteer clinic if you qualify, or a certified preparer who will quote you in writing. Fees vary and nothing official sets them, so compare two quotes. Our guide to choosing a tax preparer lists what to ask, and the guide to dealing with the CRA covers letters and reviews.
Where the numbers come from
Filing and payment dates come from the Canada Revenue Agency‘s page on 2025 return due dates. The warnings about tax schemes and preparers come from CRA pages on those topics. Tax amounts in the examples come from our own calculators, which use 2026 federal and Ontario rates from official tax tables. We’re an independent site, and no government body is behind it. We couldn’t find dates for the 2026 return yet, so check the CRA page next spring before you plan around a date.
Frequently asked questions
What are tax solutions?
It's a broad term for anything that helps you file, estimate or reduce tax legally: software, a preparer, a free clinic or a calculator. The right one depends on how complicated your year was.
Do I need a tax professional?
Not for a simple return with slips only. A self-employed income, a corporation or a large sale of property is where a preparer starts to earn their fee.
Is there a way to get free help with my return?
The CRA lists free tax clinics for people with a modest income and a simple return. We left out the income limits because CRA pages differ, so check the current page.
Can a tax solution guarantee a bigger refund?
No. A refund is tax paid minus tax owed. The CRA warns about preparers who promise unusually large refunds.
When is the 2025 return due?
April 30, 2026 for most people, and June 15, 2026 to file if you or your spouse ran a business. Any balance was still due April 30.
