Tax season can feel overwhelming, especially if your situation has changed over the past year. New income sources, life events, or CRA rule updates can all affect how and when you file. With tax season approaching 2026, understanding what to expect can help you prepare early and avoid common mistakes.
This guide walks through key filing dates, refund expectations, CRA audit focus areas, and what Canadians should gather before filing. The goal is simple: help individuals and families file accurately, on time, and with fewer surprises.
2026 Canadian Tax Season Changes (What to Expect)
Every tax season follows the same basic structure, but small changes can affect processing times, refunds, and CRA reviews. In 2026, Canadians should expect continued scrutiny around digital income, rental activity, and home office claims. Processing delays may also occur during peak filing periods.
Preparing early remains one of the best ways to reduce stress and minimize errors.
When Does Tax Season Start in Canada for 2026?
Tax season typically begins in late February, when the CRA opens electronic filing. This is when most tax software allows you to submit your return.
CRA Filing Deadlines for Individuals (2026):
- February 2026: Most tax slips become available
- April 30, 2026: Filing and payment deadline for most individuals
- June 15, 2026: Filing deadline for self-employed individuals
- April 30, 2026: Payment deadline for everyone, including the self-employed
For a full list of important personal tax dates, deadlines, and filing details , visit the official CRA resource on personal income tax deadlines and payment dates.
Even if you have until June 15 to file, any balance owing is still due by April 30. Filing early can help you receive refunds faster and avoid last-minute issues.
Different situations? Different deadlines:
Who must file a tax return Canada?
Many Canadians assume they do not need to file if they earned little or no income. Filing is often required or strongly recommended.
You should file a return if you:
- Earned employment, self-employment, or investment income
- Are new to Canada
- Want to receive benefits such as the GST/HST credit or Canada Child Benefit
- Are a student, retiree, or gig worker
- Owe tax or were asked by the CRA to file
Filing also ensures the CRA has up-to-date information to calculate benefits and credits correctly.

How Tax Refunds Work in Canada (CRA Rules)
A tax refund is not a bonus. It is simply the return of tax you overpaid during the year.
Refunds are calculated by comparing:
- Tax withheld at source, such as from pay cheques
- Total tax owed based on your income and deductions
Factors That Influence Refund Size
Refund amounts can change year to year due to:
- Changes in income
- RRSP contributions
- Tuition credits
- Taxable benefits
- Investment income
- Changes to personal credits
If less tax was withheld during the year, your refund may be smaller or you may owe tax, even if your income stayed the same.

HST and Credits: What Canadians Should Remember in 2026
The Harmonized Sales Tax affects individuals and small business owners differently.
For individuals, filing a return is required to receive the GST/HST credit. This credit is paid quarterly and helps offset sales tax costs for eligible Canadians.
Small business owners must pay closer attention to HST registration, collection, and remittance rules. Missing filings or underreporting HST can increase the likelihood of CRA follow-ups.
How HST and Credits Affects Individuals vs Small Business Owners in Canada
| Area | Individuals | Small Business Owners |
| Tax Return Requirement | Must file a personal tax return to receive the GST/HST credit | Must file returns to report income and HST activity |
| GST/HST Credit | Paid quarterly to eligible Canadians to help offset sales tax costs | Not eligible for the GST/HST credit |
| HST Registration | Not required | Required once revenue exceeds the small supplier threshold |
| HST Collection | Not applicable | Must charge HST on taxable goods and services |
| HST Remittance | Not applicable | Must remit collected HST to the CRA on time |
| CRA Risk Areas | Missing filings can delay credits | Underreporting or late filings increase CRA follow-ups |

CRA Audit Focus Areas to Watch in 2026
While most Canadians are never audited, the CRA does review returns that show certain risk indicators.
Common focus areas include:
- Gig and self-employment income from digital platforms
- Rental income and short-term rentals such as Airbnb
- Home office expenses claim
- Large fluctuations in refunds from one year to the next
- HST compliance for small businesses
Being selected for review does not mean wrongdoing. Clear records and accurate reporting usually resolve issues quickly.
What to Prepare Before Filing Your 2026 Tax Return
Organizing documents early can save time and prevent missed income or deductions.
Common documents include:
- T4 slips from employers
- T5 slips for investment income
- RRSP contribution receipts
- Tuition and education slips
- Donation receipts
- Medical expenses receipts
- Rent or property tax statements
Keeping records digitally can make retrieval easier if the CRA requests clarification later.
Common Tax Filing Mistakes Canadians Make
Mistakes are common, especially for first-time filers or those with multiple income sources.
Frequent issues include:
- Missing tax slips
- Forgetting RRSP or FHSA contribution deadlines
- Claiming ineligible deductions
- Ignoring taxable benefits
- Filing late or not filing at all
Even small errors can result in reassessments, delays, or interest charges. This is why many individuals and families choose to work with our experienced tax experts in Ottawa, who can review filings for accuracy, flag risks early, and help prevent avoidable CRA issues before they arise.
