Updated Checked by the Tax-Services.ca editorial team How we check
You’ve got three real ways to get your tax return filed in Canada: free help from a volunteer clinic, certified software you use yourself, or a paid preparer. Which one fits depends on how tangled your year was, and that matters far more than which brand is on the door. On $52,000 of employment income in Ontario with $7,000 withheld, our tax refund calculator shows a $374.57 refund, and any route should land close to that.
Who can get tax return help for free?
Community organizations run free tax clinics for people with a modest income and a simple tax situation. The CRA describes this on its community volunteer income tax program page and has a locator tool where you enter your location. Simple usually means pay from a job, benefits or no income at all. Not a rental building and a side business.
The income cut-off is where it gets fuzzy. An older CRA summary we saw gave $35,000 for one person, $45,000 for a couple and $2,500 more per dependant. We couldn’t confirm the current figures, and clinics are allowed to set their own limits. Call first.
Some certified software also has a free version. The CRA describes these as offers for people with modest income, a simple return, or living in certain provinces, and it tells you to read the eligibility on each company’s own site. Do that first.
What do certified tax software and NETFILE do?
NETFILE is the CRA’s service for filing electronically. You use software the CRA has certified, and the CRA lists 16 providers for the 2025 tax year. The software does the arithmetic and sends the return. You type in what’s on your slips, and the CRA explains the service on its NETFILE overview page.
The CRA’s NETFILE page lists getting an access code as a step. It doesn’t say there where the code comes from, so follow your software’s own instructions. For the 2025 return the service is open until 29 January 2027, and amended returns go through ReFILE.
One thing the CRA is blunt about: it doesn’t review the privacy policies of the software makers, and it isn’t liable for calculation errors. So you own the result, which is a good reason to run your own estimate first with the income tax calculator and compare the two before you hit send.
When does a paid preparer make sense?
Pay someone when your return has moving parts, and skip it when it doesn’t. Self-employment income, rental property, selling shares or a property, a move between provinces, or a year abroad all qualify. A preparer does the same job as software, plus a second pair of eyes.
We can’t tell you what any firm charges. Fees vary, and we didn’t verify prices for H&R Block, a national preparer used here only as an example, or for anyone else. Ask for the fee in writing before you hand over your slips, and ask whether it changes if you turn up with extra forms, a second province or a late-filed year from before.
| Option | Best for | What to check first |
|---|---|---|
| Free clinic | Modest income, simple return | Income limit and what the clinic handles |
| Certified software | You’re comfortable with your slips | Whether your slips fit the free tier |
| Paid preparer | Business, rental or investment income | Fee in writing and who signs the return |
Picture Jordan, a student with one T4 from a summer job and a tuition slip. Software or a clinic is plenty. Now picture Jordan’s aunt, who sold a cottage and rents out a basement suite. She’ll probably want a person looking over her shoulder.
What should you have ready before you ask for help?
Bring your social insurance number, last year’s notice of assessment if you have one, and every slip: T4s, T5s, tuition slips, RRSP receipts. Add receipts for anything you plan to claim, such as donations, medical costs or child care. Clinics and preparers both work faster when the pile is complete, and a missing slip is the most common reason a return gets delayed. If a slip is late, say so up front rather than guessing a number.
How can you check the number you’re given?
Run the same income through an independent estimate. For that $52,000 example the tool shows $6,625.43 of tax against $7,000 withheld, so a $374.57 refund. If a preparer says you’re getting $2,000, ask what they claimed that the estimate didn’t. There might be a good reason, such as tuition or medical costs.
The take-home pay calculator is handy for a second check on withholding. At $45,000 a year in Ontario, it shows $3,338.20 of federal tax and $1,904.82 of provincial tax held back, plus CPP and EI. If your T4 shows much less than that, expect a balance owing.
What mistakes should you avoid on a first return?
- Filing before all your slips arrive, then needing to amend.
- Skipping the return because you earned little, when a refund might be waiting.
- Giving your CRA sign-in details to anyone at all. Only type them on the official CRA sign-in page.
- Letting a preparer deposit your refund into an account that isn’t yours.
Deadlines matter too. For the 2025 return the filing date was 30 April 2026, and 15 June 2026 for the self-employed with tax still due on 30 April. The CRA hasn’t published dates for the 2026 tax year yet. Free help from a clinic beats a late penalty, even if it only saves you a few bucks.

Frequently asked questions
Can I file my tax return for free in Canada?
Often yes. Volunteer clinics help people with modest income and simple returns, and some certified software has a free tier with its own limits.
What is NETFILE?
It is the CRA's electronic filing service, used through CRA-certified software. Getting an access code is one of the steps the CRA lists.
Can I still file the 2025 return?
Yes. The CRA says NETFILE stays open until 29 January 2027, but late filing can bring penalties and interest.
How do I know a preparer's number is right?
Run your income through an independent estimate and ask the preparer to explain any big gap between the two.
Should I share my CRA login with a preparer?
No. Enter it only on the official CRA sign-in page. The CRA says anyone signing in for someone else must use its Represent a Client service.
