Updated Checked by the Tax-Services.ca editorial team How we check
Free tax filing in Canada comes in three forms: CRA-certified software with a free tier, a free tax clinic run by volunteers if your income is modest and your return is simple, or a paper return. The CRA says most software prepares a basic return at no cost, but a fee is usual once your return gets more complex.
Where does free filing come from?
Every company that sells online tax software has to get its product certified by the CRA each year. Some programs offer a free version, and eligibility depends on your income or your tax situation. The CRA says most software prepares a basic return at no cost for people with a modest income, but otherwise there is usually a service fee. Read the terms on the provider's own site for the tax year you are filing.
The second route is a free tax clinic. If you are eligible, volunteers prepare your return at no cost. The program sets the eligibility rules, so ask before you book.
Who can use a free tax clinic?
The CRA says these clinics are for people with a modest income and a simple tax situation, and volunteers complete the return. Think of a student with a T4 and a tuition slip, or a retiree whose income is a pension and some interest. Rental income, a business, or a big sale of shares usually lands outside that. Quebec has its own parallel program, so Quebec residents should look there. The CRA’s free tax clinics page explains the program and how to find one near you.
The CRA raised the clinic income thresholds when the 2026 filing season opened in February 2026, but we did not find the new dollar amounts on the pages we read, so we do not quote them. Host organizations can also set local limits. Phone first, since each clinic has its own income limits and bring-along list. Most want photo ID, your SIN and every slip you’ve received.
What should you check before you pick tax software or a clinic?
| Question | Why it matters |
|---|---|
| Is the product on the CRA certified list? | Only certified products can send a return through NETFILE |
| Which forms does the free tier include? | Rental, business or investment income may need a paid tier |
| Does it support Auto-fill my return? | It fills in parts of your return from CRA records |
| Are prior years included? | Certified software covers 2018 to 2025 returns |
| What does support cost? | Live help may cost extra |
| Can you print or save the return? | You may need a copy for a loan or rental |
Lay the free tier’s form list next to your own slips before you choose.
Can you still file a 2025 tax return online?
Yes. NETFILE and ReFILE opened on February 23, 2026 and stay open until January 29, 2027, so late 2025 returns can still go in online. That doesn’t move any deadline or waive interest, though, and a balance owing is still due on time. The tax refund calculator states that balances are due by April 30.
What should you have ready before you start?
Gather your slips first: T4s from employers, T5s from banks and RRSP receipts. If the software offers Auto-fill my return, you’ll need to be signed in to your CRA account, and it’s still worth comparing the slips it pulls in against the paper or PDF copies, since a missing one is easy to miss. Save the finished return as a PDF before you submit it. You may need it later for a loan, a rental application or a benefit review.
Could cheap tax software cost you money?
It can, if it misses a claim. Take a single person in Ontario with $60,000 of employment income and $8,000 of tax withheld. The tax refund calculator shows tax for the year of $8,320.50, so they owe $320.50. Add a $3,000 deduction, such as an RRSP contribution, and tax falls to $7,566.72, which turns the balance into a refund of $433.28.
Software only uses the deductions you enter. Miss that $3,000 and you’ve missed $753.78 of tax relief in this case, so a product that overlooks claims can cost you more than a paid one that finds them.
To see how your total tax is built, use the income tax calculator. For credits people forget, try the tax credits calculator. Filing also decides which benefits you receive, and the GST/HST credit calculator shows one of them.
Should you file if you had no income?
Usually, yes. Benefits such as the GST/HST credit and the Canada Child Benefit are worked out from your return, so skipping it can mean waiting on money you were owed. A return with a handful of zeros takes minutes in any free software, and it’s the one case where the price really is zero.
What are the catches?
- Don’t assume the free tier covers every slip. Check the list of forms first.
- Keep your receipts. The software doesn’t verify them.
- Read the privacy terms and the upsell screens before you enter your details.
- We couldn’t confirm which brands offer a free tier this year, or on what terms, so we don’t claim any.
How do you file taxes online with the Canada Revenue Agency?
You file taxes online by sending your tax return to the Canada Revenue Agency through CRA-certified software. That route is called NETFILE, and it is the one most free tiers use.
- Pick a certified product and check which forms its free tier includes.
- Sign in to your CRA account if you want Auto-fill my return to bring in your slips.
- Enter or confirm your income, deductions and credits.
- Submit the return, then save a PDF copy.
The software only sends what you entered, so check each slip against your own copy before you submit.

Frequently asked questions
Can I file my Canadian taxes for free?
Yes, if your return is basic. The CRA says most certified software will prepare a basic return for free for people with a modest income and a simple tax situation, and some providers limit free offers by province. Free tax clinics also exist for eligible people, so check both before you pay for anything.
Does free software have to be certified?
To send your return online through NETFILE, yes. The CRA certifies third-party software each year and publishes the list, and you need a product certified for the tax year you are filing. An uncertified program may still print a return, but it cannot transmit it through NETFILE.
Is a free return less accurate?
Not by itself. A program only uses what you enter or import, so the result depends on your slips and claims. The risk with free tiers is a missing form or a claim you did not know about, not the arithmetic. Compare the form list against your own slips first.
Can I still file a 2025 return late online?
Yes. NETFILE and ReFILE are open from February 23, 2026 until January 29, 2027, and NETFILE covers initial returns for 2018 to 2025. That does not move the filing deadline or waive late-filing penalties and interest, and a balance owing was still due April 30, 2026.
Who can use a free tax clinic?
People with a modest income and a simple tax situation, according to the CRA. Volunteers prepare the return. Rental income, a business or large investment sales usually fall outside it. The CRA raised the income thresholds for the 2026 season and clinics can set local limits, so ask the clinic before you book.
When would I need a paid tier?
Rental, business or complex investment income often calls for one, and so does live help from a person. Check the free tier's form list before you start, and read the provider's terms for the tax year you are filing, since free offers change from year to year.
