The CRA 2026 tax season changes affect how Canadians file their returns, access tax documents, receive notices of assessment and manage their tax information online.
The 2026 filing season relates primarily to income earned between January 1 and December 31, 2025. It should not be confused with the tax brackets and credit amounts applying to income earned during the 2026 calendar year, which will generally be reported on tax returns filed in 2027.
For Canadians filing a 2025 income tax and benefit return, the most important developments include a lower federal tax rate, a new top-up tax credit, more digital CRA correspondence and changes to CRA account security.
The Canada Revenue Agency officially opened online filing on February 23, 2026.
What Changed for the 2026 Tax Season?
The main CRA changes for the 2026 tax-filing season include:
- A reduced lowest federal income tax rate for the 2025 tax year
- A new non-refundable top-up tax credit
- Greater use of digital notices of assessment
- New backup multi-factor authentication options
- Easier online recovery of CRA account access
- Changes to how taxpayers obtain copies of tax slips
- Expanded online payment-arrangement services
- Wider access to SimpleFile services
- Permanent closure of CRA drop boxes after the filing season
Most taxpayers do not need to calculate all these changes manually. CRA-certified tax software generally applies the relevant federal and provincial calculations automatically.
However, understanding the updates can help taxpayers check their returns, prepare the right documents and avoid processing delays.
What Are the CRA Tax Deadlines for 2026?
Online filing for 2025 income tax and benefit returns opened on February 23, 2026.
For most individuals, the deadline to file a 2025 income tax and benefit return was April 30, 2026. Any outstanding personal income-tax balance was also due by April 30.
Self-employed individuals—and people whose spouse or common-law partner was self-employed—have until June 15, 2026, to file. However, any tax owed was still payable by April 30, 2026.
The CRA publishes all current deadlines on its official personal income-tax due dates page.
Key CRATax Dates for 2026
| Tax event | 2026 date |
|---|---|
| Online filing opened | February 23, 2026 |
| RRSP contribution deadline for the 2025 return | March 2, 2026 |
| Filing deadline for most individuals | April 30, 2026 |
| Payment deadline for personal income tax owed | April 30, 2026 |
| Self-employed filing deadline | June 15, 2026 |
Filing late can lead to penalties when tax is owed. Delayed filing may also interrupt income-tested benefits and credits because the CRA uses information from annual tax returns to calculate eligibility.
For example, filing a return can affect entitlement to the GST/HST credit, the Canada Child Benefit and the Canada Workers Benefit.
How Did the Lowest Federal Tax Rate Change?
One of the most significant CRA 2026 tax season changes is the reduction in the lowest federal individual income-tax rate.
The lowest rate was reduced from 15% to 14%, effective July 1, 2025. Because the change took effect halfway through the year, the lowest rate used for the full 2025 tax year is effectively 14.5%.
The lowest federal tax rate applies only to income within the first federal tax bracket. It does not apply to a taxpayer’s entire income when taxable income exceeds that threshold.
Income above the first bracket continues to be taxed at the applicable higher marginal rates.
The final effect of the rate reduction depends on factors including:
- Taxable income
- Province or territory of residence
- Available deductions
- Non-refundable tax credits
- Payroll tax already withheld
- Self-employment income
- Pension income
- Investment income
- Rental income
Employees may already have received part of the benefit through adjustments to payroll deductions during the second half of 2025.
Canadians who need a broader explanation of how income is reported can also read the ENBusiness.ca guide to Line 15000 on a Canadian tax return.
What Is the New Top-Up Tax Credit?
The reduction in the lowest federal rate also affects the value of many non-refundable tax credits because these credits are normally calculated using the lowest federal marginal tax rate.
To limit unintended reductions for certain taxpayers, a new federal top-up tax credit was introduced.
The credit is intended to maintain an effective 15% rate for certain non-refundable tax credits claimed on amounts above the first federal income-tax bracket threshold of $57,375 for 2025.
The calculation may apply to eligible credits entered on the federal worksheet and is reported through Line 34990 of the return where applicable.
Taxpayers using CRA-certified tax software should generally have the calculation completed automatically. People completing a paper return should follow the instructions in the relevant 2025 federal income-tax package.
Because tax credits and deductions do not all work in the same way, taxpayers should check the rules for each amount before claiming it.
Are Notices of Assessment Now Digital?
The CRA has increased its use of digital notices of assessment and reassessment.
After a return has been received and processed, the notice may be made available through CRA My Account rather than being automatically sent as a paper document.
A notice of assessment confirms whether the CRA accepted the return as filed or made changes to it. It may show:
- A refund
- A balance owing
- Available RRSP deduction room
- Home Buyers’ Plan information
- Lifelong Learning Plan information
- Explanations of adjustments
- Carry-forward amounts
- Updated benefit information
Taxpayers should not assume that the process is complete immediately after submitting a return. The notice of assessment should be reviewed carefully to identify missing income, adjusted credits or differences between the filed return and the CRA’s calculation.
Anyone relying on paper correspondence should review their communication preferences and confirm how future CRA documents will be delivered.
Taxpayers can access the official CRA account sign-in page to check their return status, notices and account information.
What Changed With CRA Account Security?
The CRA expanded its online account-security measures during the 2026 filing season.
Account users may be prompted to add a backup multi-factor authentication method. Available methods may include a passcode grid or a third-party authenticator application.
A backup authentication option can help users regain access when their primary authentication method is unavailable.
The CRA has also introduced a self-service option that may allow users to recover account access by completing the online registration process again. This can reduce the need to contact the CRA by telephone when login credentials or security-question answers have been forgotten.
Anyone without an account can review the official instructions for registering for a CRA account.
Before signing in, taxpayers should confirm that they are using an official Government of Canada webpage. Fraudulent emails, text messages, social-media posts and paid search advertisements may imitate CRA services to steal passwords, Social Insurance Numbers or banking information.
The CRA will not ask taxpayers to send passwords, banking login information or cryptocurrency payments through an unsolicited email or text message.
Can Tax Slips Still Be Requested by Phone?
Individuals and authorized representatives can no longer request paper copies of certain tax slips by telephone.
Copies of documents such as T4, T4A and T5 slips should instead be obtained through CRA My Account or directly from the employer, financial institution or organization that issued them.
Most employers and financial institutions issue slips by the end of February. However, slips may not appear in CRA My Account immediately because the CRA must first receive and process the information.
Taxpayers should compare the slips in their own records with those displayed online before filing. Filing before all income slips are available can result in an incomplete return and a later reassessment.
Documents to Collect Before Filing
Common documents include:
- T4 employment income slips
- T4A pension and other income slips
- T5 investment income slips
- T3 trust income slips
- T4E Employment Insurance slips
- T4OAS and T4CPP slips
- RRSP contribution receipts
- Medical-expense receipts
- Childcare receipts
- Tuition information
- Donation receipts
- Home-office expense records
- Business income and expense records
- Rental income and expense records
- Foreign income information
- Capital-gains transaction records
Income from different sources may contribute to the amount reported on Line 15000. Taxpayers who are unsure what should be included can consult the ENBusiness.ca explanation of what Line 15000 means.
Where Can the NETFILE Access Code Be Found?
The NETFILE access code is an eight-character code containing letters and numbers. It can be used when submitting a return electronically through approved tax software.
The code can generally be found on the previous year’s notice of assessment. It is also available through CRA My Account.
Beginning in February 2026, the code became easier to locate within the tax-returns section of CRA My Account.
ENBusiness.ca has a separate step-by-step guide explaining where to find a NETFILE access code.
A tax return may still be accepted without the code in some circumstances. However, certain information from the previous return may not be available for identity-verification purposes.
Taxpayers should never share a NETFILE access code publicly or send it through an unsecured message.
Can CRA Payment Arrangements Be Created Online?
Taxpayers with eligible personal tax or COVID-related benefit debts of at least $1,000 may be able to use the CRA’s Manage Balance service.
Depending on eligibility, the service may allow a taxpayer to:
- Make a full payment
- Make a partial payment
- Propose a payment arrangement
- Schedule payments
- Review amounts owing
- Manage payments without immediately speaking to a collections officer
- Request a callback when direct support is required
The availability of an online payment arrangement does not automatically stop interest from accumulating. Taxpayers should review the terms carefully and pay as much as reasonably possible by the payment deadline.
The CRA explains the available methods on its official payments to the CRA page.
People experiencing difficulty paying should communicate with the CRA rather than ignoring an outstanding balance. Late-payment interest and collection action may continue when no arrangement has been made.
Who Can Use SimpleFile in 2026?
SimpleFile is intended for eligible people with lower incomes and straightforward tax situations.
The CRA’s 2026 SimpleFile services opened on March 9, 2026. Some individuals received invitations, while others may be able to check their eligibility through a CRA questionnaire.
Available filing methods may include digital and telephone-based services.
SimpleFile is not suitable for every taxpayer. People with self-employment income, rental properties, foreign assets, complex investments or substantial deductions may need certified tax software or professional assistance.
Eligible Canadians with modest incomes and simple tax situations may also be able to receive free help through a Community Volunteer Income Tax Program clinic.
Filing is important even when a person has little or no tax to pay. An annual return can be required for income-tested benefits such as the Canada Workers Benefit and the GST/HST credit.
How Does Filing Affect the Canada Workers Benefit?
The Canada Workers Benefit is a refundable tax credit for eligible individuals and families earning employment or self-employment income.
The CRA determines eligibility and calculates the amount using information reported on a tax return.
Eligible recipients may also receive part of the benefit early through Advanced Canada Workers Benefit payments.
This means that failing to file a return can affect both the annual CWB claim and future advance payments. Taxpayers waiting for an upcoming payment can review the confirmed Canada Workers Benefit payment dates for 2026.
The precise amount depends on income, marital status, province or territory, dependants and Disability Tax Credit eligibility.
How Does Filing Affect GST/HST Credit Payments?
The GST/HST credit is a tax-free quarterly payment for eligible individuals and families with low or modest incomes.
A separate annual application is not normally required. Instead, the CRA uses information from the income tax and benefit return to determine eligibility.
Even a person with no taxable income may need to file a return to receive the credit.
Changes to income, marital status, number of children or residency can affect the payment amount. More information is available in the ENBusiness.ca guide to the GST/HST credit in Canada.
Taxpayers should ensure that the CRA has current address, marital-status and direct-deposit information.
What Other Tax Changes Apply to the 2025 Return?
Several more targeted changes may affect particular taxpayers filing during the 2026 tax season.
Capital-gains Rollover for Small-business Shares
Under proposed changes, the replacement period for qualifying small-business shares has been extended, and the definition of an eligible small-business corporation share has been expanded for qualifying dispositions after December 31, 2024.
Tax measures described as proposed should be checked against current legislation before a taxpayer relies on them.
Disability Supports Deduction
The list of expenses eligible for the disability supports deduction has been expanded under proposed changes.
Eligibility depends on the nature of the expense and whether it was required to earn income, attend school or conduct qualifying research.
Taxpayers should retain receipts and documents showing how the expense met the applicable conditions.
Northern Residents Deductions
Haida Gwaii has been reclassified from the prescribed intermediate zone to the prescribed northern zone for the 2025 and later tax years.
Qualifying residents may therefore be able to claim a larger northern residents deduction, depending on their circumstances and the amount of time they lived in the prescribed zone.
Critical Mineral Exploration Tax Credit
The critical mineral exploration tax credit has been expanded to include additional minerals for eligible flow-through share agreements entered into after November 4, 2025, and before April 1, 2027.
This credit generally applies only in specific investment circumstances. Investors should check the relevant tax slips and obtain professional advice when necessary.
Fuel-charge Proceeds Tax Credit for Farmers
The federal fuel charge ended on April 1, 2025.
The return of fuel charge proceeds to farmers tax credit for the 2024–2025 fuel-charge year is therefore the final version of the credit available to eligible farming businesses.
Are the 2026 Tax Brackets Used for This Return?
No. The return filed during the 2026 tax season generally reports income earned during 2025.
It therefore uses the tax rates, brackets and credit amounts applying to the 2025 tax year.
The federal brackets announced for income earned between January 1 and December 31, 2026 will generally be used when Canadians file their 2026 returns in 2027.
For income earned in 2026, the lowest federal rate is 14% and applies to the first $58,523 of taxable income. Federal bracket thresholds and certain personal amounts have also been indexed.
Current rates and thresholds are available on the Government of Canada’s federal income-tax rates and brackets page.
This distinction is important when estimating payroll deductions or planning income, deductions and tax instalments for the current year.
Are CRA Drop Boxes Closing?
The CRA announced that its remaining drop boxes at 45 locations across Canada would permanently close on May 29, 2026, after the main tax-filing season.
After the closures, taxpayers submitting paper documents should use an approved mailing address or another official submission method listed by the CRA.
Documents should not be left at a CRA office unless the location and submission method are officially authorized.
Taxpayers mailing time-sensitive documents should retain:
- A complete copy of the documents
- The correct CRA mailing address
- Proof of the mailing date
- Postal tracking where available
- Any relevant CRA reference number
People filing a paper return can review the ENBusiness.ca guide explaining where to mail a Canadian tax return.
How Long Should Tax Records Be Kept?
Taxpayers should generally keep supporting records for at least six years from the end of the tax year to which the records relate, unless a different retention rule applies.
Documents may include:
- Tax slips
- Receipts
- Invoices
- Bank statements
- Investment records
- Property purchase and sale documents
- Business ledgers
- Mileage records
- Rental-property records
- Donation receipts
- Medical documentation
- Proof of childcare expenses
- Foreign income records
The CRA may request supporting documents after a return has been assessed. A refund or notice of assessment does not prevent the CRA from reviewing information later.
Digital copies should be readable, complete and stored securely.
How Can Canadians Prepare for CRA Tax Filing?
A careful filing process can reduce the risk of errors, reassessments and delayed refunds.
Before submitting a return:
- Confirm access to CRA My Account.
- Update the mailing address and contact details.
- Update marital-status information where necessary.
- Confirm direct-deposit information.
- Collect all tax slips and receipts.
- Compare personal records with slips available through the CRA.
- Use current CRA-certified tax software.
- Report employment, investment, benefit and pension income.
- Include rental and self-employment income where applicable.
- Review all deductions and credits before submitting.
- Save the NETFILE or EFILE confirmation number.
- Check the notice of assessment for CRA adjustments.
- Keep supporting records for the required period.
Taxpayers with business income, foreign property, cryptocurrency transactions, rental properties, significant capital gains or major life changes may benefit from advice from a qualified Canadian tax professional.
What Should You Do After Filing a Tax Return?
After filing, taxpayers should:
- Save the electronic filing confirmation
- Check the return status through CRA My Account
- Review the notice of assessment
- Confirm the expected refund or balance owing
- Pay any outstanding amount
- Respond promptly to CRA requests
- Retain all supporting documents
- Update benefit and account information when circumstances change
The CRA provides an official service for checking income-tax refund information and refund status.
Processing may take longer when a return is selected for review, contains incomplete information or differs from tax slips already received by the CRA.
Final Considerations
The CRA 2026 tax season changes place greater emphasis on digital filing, online account access and electronic correspondence.
The reduced federal tax rate may provide savings for many Canadians, while the top-up credit is intended to preserve the value of certain non-refundable credits.
At the same time, taxpayers need to pay closer attention to CRA My Account because notices, slips, filing information and account-security tools are increasingly delivered online.
Annual filing also remains important for accessing income-tested programs such as the GST/HST credit, Canada Workers Benefit and Canada Child Benefit.
Tax rules depend on individual circumstances. Canadians dealing with self-employment, foreign assets, capital gains, rental income or complex deductions should verify the latest CRA guidance or seek advice from a qualified Canadian tax professional before filing.
