What Do You Need Before You Start?
Certified software is the first requirement, not an optional extra. The Canada Revenue Agency certifies tax software from third-party developers each year. Only that certified software can calculate and file a return electronically. Skipping this step blocks the return from going through at all, so confirming certification matters more than picking the flashiest interface.
Reviewing software details before committing saves headaches later. Not every program covers every situation, so checking that a package handles self-employment income, rental property, or provincial credits before filing prevents a mid-return surprise. This is where tax software help becomes valuable for anyone unsure which product fits their filing profile.
When Can Taxpayers Actually Submit Their Return?
Timing follows a fixed government schedule, not personal convenience. NETFILE and ReFILE open for transmission starting Monday, February 23, 2026, at 6:00 a.m. Eastern time, and stay open until Friday, January 29, 2027. Filing outside that window through these systems isn’t possible.
Can Older Tax Years Still Be Filed Electronically?
Yes, within limits. NETFILE currently accepts initial returns for the 2018 through 2025 tax years. ReFILE supports amended returns for 2022 through 2025. For anyone weighing diy tax filing canada against professional help, Unity Financial Services prepares personal returns for individuals across every Canadian province as an alternative to software-only filing.
How Do You File Your Return Step by Step?
Filing a personal return with certified software follows a predictable order, from gathering slips to confirming a NETFILE confirmation number. Skipping a step usually means a delayed return or a rejected submission, so following the order matters.
Gather tax slips first. Collect T4s, T5s, RRSP receipts, and any self-employment records before opening the software.
Import prior-year data. Many software platforms let taxpayers upload last year’s T1 return and connect to the CRA’s Auto-fill service to pre-populate slips automatically, cutting down manual entry errors.
Answer guided questions. Most consumer tax software walks users through a simple question-and-answer format and builds the return based on those answers, rather than requiring blank-form entry.
Choose a filing path. Some platforms offer a do-it-yourself route, while others include a full-service option where a dedicated expert completes the return from start to finish.
Review self-employment sections carefully. Self-employed filers need software built to handle freelance income, ranging from a single contract to more complex, multi-source returns.
Submit through NETFILE. Confirm the return, transmit it, and save the confirmation number for records.
What if a mistake shows up after filing?
Taxpayers who spot an error after submitting an initial T1 return do not need to start over. T1 tax software support built into certified platforms allows filers to use ReFILE to submit amended returns for recent tax years, correcting figures without a paper amendment.

What should a filer do if the tax software freezes or shows an error?
Before opening a return, confirm the program has the most recently updated version installed by checking the developer’s website. Outdated versions cause many of the errors filers see mid-season, and a quick update often resolves the issue.
