Updated Checked by the Tax-Services.ca editorial team How we check
Free NETFILE in Canada isn’t a product you sign up for. NETFILE is the CRA’s service for sending a personal return online, and it costs nothing itself. What you may pay for is the certified tax software that prepares the return, and plenty of that software has a free version.
What is free NETFILE, exactly?
Two pieces are involved, and mixing them up is how people end up paying for nothing. The CRA runs the transmission service. A separate company makes the software that does the arithmetic and talks to the CRA. Only software the CRA has certified can send a return through NETFILE.
So the question isn’t “how do I get free NETFILE”. It’s “which certified software costs me nothing for my situation?” The CRA keeps a list on its tax software for filing personal taxes page, and you can filter it by price, platform and limitations. The page we read showed 17 certified providers for 2025, in online, mobile and download formats.
Who can use it, and when?
| Item | What the CRA says |
|---|---|
| Identification | A SIN starting with 1 to 9, a temporary tax number starting with 01 or 03, or a SIN starting with 0 for newcomers |
| Opening date | Monday, February 23, 2026, 6:00 a.m. ET |
| Closing date | Friday, January 29, 2027 |
| Returns you can send | Tax years 2018 to 2025 |
| Amending a return | Years 2022 to 2025, through ReFILE |
| Quebec residents | File the provincial return with Revenu Quebec |
Some returns can’t go through NETFILE at all. That includes returns for a deceased person, bankruptcy returns, Lloyd’s of London income, foreign tax credits from more than three countries and SR&ED claims. If you’re in one of those groups, you’ll file a different way.
How do you find software that’s really free?
The CRA says that with a modest income, most software will prepare a basic return at no charge, and otherwise there’s usually a fee. Some tools let you pay what you like. Others charge for extras, such as a more complex return, even when the basic one is free.
We won’t rank products here, because we can’t confirm prices or limits, and they change every year. Instead, check three things on the provider’s own page before you start typing.
- Does the free version cover your income sources, such as a T4, tuition or self-employment?
- Is the price shown before you enter your data, not at the last screen?
- What does the privacy policy say? The CRA doesn’t review those.
One more habit helps. If a program asks for a credit card before it shows you a total, close the tab and try another. A free return shouldn’t need one.
What do you need to have on hand?
Your slips, your social insurance number and last year’s return for reference. If you’re sending through NETFILE, the software will also ask for an access code, which you can find in your CRA account. Newcomers with a SIN starting with 0 or a temporary tax number can use the service too, as the table shows.
Here is a habit people who file every year swear by at tax time: make one folder, paper or digital, and drop each slip in as it arrives. In March, when the T5 from the bank shows up, you won’t have to reopen a return you thought was finished.
A quick example before you file
Say you earned $45,000 in Ontario and your employer withheld $6,000. The tax refund calculator puts your tax at $5,243.01, so you’d get about $756.99 back. Add $2,000 of deductions, an RRSP for instance, and tax falls to $4,862.01. The refund grows to $1,137.99.
Run your own figures first. If your software shows something wildly different, you’ve probably missed a slip or mistyped a box. The income tax calculator gives a second opinion, and the tax credits calculator shows what the federal credits are worth.
What free software won’t do for you
It won’t decide whether a claim is right, or catch the slip your employer mailed late, or tell you that the credit you skipped was worth a few hundred dollars. The CRA is clear that the software developer and the user are responsible for the result, and the CRA can’t be blamed if a programming error affects the amounts. Read every line before you send.
Owing money is a separate matter. Our refund calculator notes that balances are due by April 30, and the CRA’s important dates page lists other deadlines. If you owe tax on income with nothing withheld, see the tax installments calculator. To plan next year’s deduction, try the RRSP calculator.
We couldn’t confirm the rules or income limits for free tax clinics, so check the CRA page before you count on one.
