The best tax software in Canada for most simple returns is Wealthsimple Tax because it is CRA-certified, free with optional paid services, and supports common slips, credits, Auto-fill My Return, NETFILE, ReFILE, and T1135. TurboTax is best if you want more guided support, expert help, or a full-service filing option. UFile is a strong traditional choice, especially for families, Quebec filers, and some situations where its CRA details list support for emigrant returns and Form T2203. H&R Block is best if you want an online product tied to a large tax-preparation brand. StudioTax is best for desktop users who want local software rather than an online-first workflow.
Key takeaways
- Use CRA-certified software for the exact tax year you are filing.
- Quebec residents should also check Revenu Quebec authorization.
- Free software is enough for many simple and moderate returns.
- Expert-help upgrades are useful when the issue is tax judgment, not data entry.
- Desktop software can be better if you dislike storing tax data online.
- Complex returns may be blocked from NETFILE or unsupported by specific products.

Pros and cons
Pros
- Faster than paper filing for many taxpayers.
- Built-in calculations reduce manual arithmetic.
- Auto-fill My Return can import many CRA slips.
- NETFILE provides electronic submission.
- Some software supports ReFILE for amendments.
Cons
- Certification does not mean every tax situation is supported.
- Free plans may have restrictions or optional upgrades.
- Tax software cannot replace professional advice for complex planning.
- Imported slips still need to be checked.
- Some returns cannot be filed through NETFILE.
Tax software can calculate only from the information you enter or import. Review every slip, deduction, credit, province, marital-status answer, dependant entry, self-employment amount, and carryforward before filing.
Start with certification, not popularity
The first test is whether the software is certified by the CRA for the specific tax year. CRA certification means the product can calculate and transmit returns through CRA systems, but it is not a recommendation and it does not guarantee the software supports every taxpayer situation.
For 2025 returns, the CRA lists the NETFILE and ReFILE transmission window from February 23, 2026, to January 29, 2027. Quebec residents also need software authorized for the Quebec personal income tax return if they want to file online with Revenu Quebec.
Wealthsimple Tax
Wealthsimple Tax is the best starting point for many Canadians because the CRA lists it as certified for 2023 to 2025, with Auto-fill My Return, NETFILE, ReFILE, T1135, free cost, and optional paid services.
Wealthsimple's own tax page describes Basic, Plus, and Pro-style support levels, with return limits and optional support features. It is a strong fit for employment income, common deductions, registered-account slips, investment slips, donations, medical expenses, families, and many self-directed filers.
The limitation is complexity. The CRA details page lists several 2025 exclusions, including some special elections and certain complex forms. If your return includes emigration, corporate rollovers, multiple jurisdictions, farm programs, or unusual foreign-affiliate reporting, check the details before using it.
TurboTax
TurboTax is best for filers who want more guidance or access to expert help. Its pricing page separates do-it-yourself filing, expert-assisted filing, and full-service filing where a tax expert prepares the return.
That range is useful if you are nervous about self-employment, rental income, investments, moving expenses, dependants, or credits. TurboTax also has online, Windows, and mobile products listed by the CRA for 2025, depending on the version.
The main caution is cost. TurboTax can be free in some situations, but paid tiers, expert help, and full service can be significantly more expensive than a basic online filing product.
UFile
UFile is a long-running Canadian tax software option with online and Windows versions. CRA details list UFile for Windows and UFile Online as certified for 2018 to 2025, with Auto-fill My Return, NETFILE, ReFILE for recent years, T1135, and support for some features such as emigrant returns and Form T2203 for 2024 and 2025.
UFile is worth comparing for families, Quebec residents, people who like a traditional interview-style workflow, and users who file multiple returns together.
The main caution is usability preference. Some users prefer newer interfaces, while others prefer UFile's more traditional workflow.
H&R Block
H&R Block's 2025 tax software includes Free, Deluxe, Premier, and Self-Employed packages. Its support page says users can access CRA and Revenu Quebec online services, download slips with Auto-fill My Return and Quebec tax-data download, and file online with NETFILE and ReFILE where applicable.
It is a practical option if you want online software from a brand with in-person tax-preparation operations. It can also be a fit when you want a clearer path to paid help.
The main caution is package fit. If you add forms or slips that require Deluxe, Premier, or Self-Employed, you may need to upgrade.
StudioTax
StudioTax is best for users who want desktop software. Its site describes StudioTax as a Windows/Mac installable program rather than an online application, and the CRA lists Windows and Mac versions as certified for 2018 to 2025. CRA details also list iOS and Android products for 2025.
Desktop software can appeal to people who want to keep data local, file several family returns, or avoid an online-first account flow.
The Quebec caveat matters. CRA details state that the StudioTax Mac version does not accept the calculation or production of the Quebec TP-1 provincial return. Quebec users should verify the exact platform and Revenu Quebec authorization before starting.
TaxTron and other certified options
TaxTron and several other products appear on CRA and Revenu Quebec software lists. These can be worth considering if you want an alternative to the largest brands or if a specific product supports a form you need.
The right way to compare smaller providers is not by brand awareness. Check certification, supported tax years, supported forms, free-return conditions, Quebec authorization, support availability, and whether you can import prior-year data.
When software is not enough
Consider a tax professional if you are filing a deceased taxpayer return, bankruptcy return, complex non-resident or deemed-resident situation, business sale, corporate rollover, foreign affiliate reporting, complex farm return, major rental-property issue, or multi-jurisdiction employment situation.
Also consider professional help if you do not understand the tax result. Software can ask questions, but it cannot reliably decide whether your answer is legally correct.
FAQ
What is the best free tax software in Canada?
Wealthsimple Tax is the best free starting point for many Canadians. Other products may offer free filing in limited situations, so check CRA details and the provider's own free-return rules.
Is Wealthsimple Tax certified by the CRA?
Yes. CRA details list Wealthsimple Tax as certified for the 2023 to 2025 tax years, with Auto-fill My Return, NETFILE, ReFILE, and T1135.
Is TurboTax worth it in Canada?
TurboTax can be worth it if you want guided software, expert assistance, or full-service filing. It is less compelling if your return is simple and a free certified option handles everything you need.
What is the best tax software for Quebec?
Quebec residents should check both CRA certification and Revenu Quebec authorization. Wealthsimple Tax, TurboTax, UFile, H&R Block, StudioTax, and TaxTron appear in Revenu Quebec's 2025 personal-tax software list, but platform and feature support can vary.
Can tax software file a self-employed return?
Many products support self-employment income, but the right choice depends on complexity. Compare business expense categories, GST/HST or QST issues, vehicle expenses, home-office expenses, inventory, farm forms, and whether you want expert help.
