CRA 2026 Tax Season Changes: Filing Guide & Updates

If you earned income in Canada during 2025, tax season 2026 has a few wrinkles worth knowing before you log into CRA My Account. The Canada Revenue Agency has shuffled several service dates, tightened digital-only access for Notices of Assessment, and is phasing out physical drop boxes for paper filers. For most Canadian workers, the April 30 deadline hasn’t changed — but the tools and timelines around it have. The CRA received over 33 million tax returns last season, with 93% filed online, and that shift to digital-first service is accelerating.

Filing deadline: April 30, 2026 · Tax season start: February 23, 2026 · Basic personal amount: $16,452 · T4 deadline: February 28, 2026 · NETFILE access: From February 23

Key filing dates and tax parameters for the 2026 season are summarized below.

What are the biggest tax changes for 2026?

The CRA’s 2026 filing season marks the most significant shift toward digital-only services in years. Starting February 2026, Notices of Assessment (NOAs) will be viewable exclusively through CRA My Account — paper notifications are being phased out entirely. The agency is also rolling out mandatory backup multi-factor authentication (MFA) for My Account access, a security upgrade that applies to all filers logging in from February onward.

Physical tax drop boxes, a longtime fallback for paper filers, will be discontinued after the 2026 tax season. If you still file by paper, you’ll need to request tax packages — they are no longer automatically mailed, with on-request availability beginning January 20, 2026.

Income tax rule updates

The CRA has adjusted several thresholds to account for inflation, including the Basic Personal Amount, which rises to $16,452 for the 2025 tax year. Federal tax brackets will be indexed to inflation, though exact bracket shifts for each province were not fully detailed in official announcements at press time.

CPP adjustments

The Canada Pension Plan contribution rate for 2026 increased to 5.95% (employer and employee each pay), with a maximum annual contribution of $3,867.50. The year’s maximum pensionable earnings rose to $68,500, up from $66,600 in 2025. These adjustments reflect the CPI indexation formula that governs CPP increases annually.

Senior deductions

For seniors aged 65 and older, the age amount credit remains available, with the supplement for those with lower incomes preserved. The senior-specific deduction thresholds are indexed to inflation, following the same annual adjustment process applied across federal credits.

Are taxes going up in 2026 in Canada?

No major federal tax rate increases are scheduled for the 2025 tax year. The federal government maintained its commitment to inflation-indexing tax brackets, which means thresholds increase to keep pace with rising prices rather than generating new revenue through rate hikes.

Federal and provincial changes

The federal Basic Personal Amount increased to $16,452 for 2025, up from $15,705 in 2024 — a $747 bump that effectively shelters more income from federal tax. Provincial amounts vary, but most provinces adjust their personal amounts in line with federal indexing or provincial legislation.

Impact on brackets

For a Canadian earning $70,000 in Ontario, the marginal federal rate remains at 20.5% on income above the first bracket threshold. The inflation adjustment means more income falls into lower brackets slightly, providing marginal relief — though the effect is modest for average earners.

How much tax do you pay on $70,000 a year in Canada?

For a single filer in Ontario earning $70,000 in 2025, federal and provincial combined income tax runs approximately $14,000–$15,500 after applying the Basic Personal Amount and federal tax credits. After CPP (~$3,500) and EI (~$1,074) deductions, take-home pay sits around $51,000–$53,000 annually.

Ontario calculator breakdown

Ontario’s provincial income tax on $70,000 taxable income applies a 5.05% rate on the first $51,446 and 9.15% on the remainder. Combined with the federal 20.5% marginal rate on income above ~$55,000, the blended marginal rate for income in the $55,000–$70,000 range approaches 32–35% depending on exact taxable income after credits.

After-tax salary

Using an online tax calculator for Ontario, $70,000 gross typically yields roughly $51,000–$52,500 net after federal and provincial income taxes, CPP, and EI. This translates to an effective tax rate of approximately 26–28% for a single filer with no additional credits.

When to file taxes 2026 Canada?

The 2026 tax season officially opens on February 23, when NETFILE begins accepting 2025 income tax returns. Auto-Fill My Return, which pre-populates tax software with CRA-held information, opens two weeks earlier on February 9.

Start date

You can file as early as February 23 via NETFILE, the CRA’s direct electronic filing service. The system operates 21 hours per day, seven days a week during peak season. SimpleFile Digital and SimpleFile by Phone, the CRA’s free guided filing options, open on March 9 for those who prefer step-by-step assistance.

Deadlines by province

The filing deadline is uniform across Canada: April 30, 2026 for most individuals. If that date falls on a weekend or holiday, returns postmarked on the next business day are considered on time. Self-employed filers and their spouses receive an automatic extension to June 15, but any taxes owed are still due by April 30.

T4 slips (employment income) must be issued by employers by February 28, 2026, though some sources cite March 2 as the official deadline — employers should confirm with their payroll providers to avoid penalties.

Here is the timeline for key filing actions you need to take.

1. Verify your CRA My Account is active and set up backup MFA before February 23
2. Gather all T4 and slips; employers must issue by February 28
3. Use Auto-Fill My Return (available February 9) to pre-populate your return
4. File via NETFILE, SimpleFile, or certified software starting February 23
5. Pay any balance owing by April 30 to avoid penalties
6. Self-employed filers: submit return by June 15, but remit payment by April 30

Is CPP going up in 2026?

Yes. The Canada Pension Plan contribution rate for 2026 is 5.95%, up from 5.70% in 2025. The maximum annual contribution increased to $3,867.50, compared to $3,722.40 the previous year. These changes follow the CPI-indexed formula that adjusts CPP rates annually based on growth in the preceding year’s average wage.

Contribution rates

Employees and employers each pay 5.95% of earnings between the basic exemption ($3,500) and the year’s maximum pensionable earnings ($68,500 for 2026). Self-employed individuals pay the full 11.9% rate, as they cover both the employee and employer portions. The maximum annual contribution translates to roughly $322 per month for those earning above the maximum.

CPI index impact

CPP benefits are also indexed to CPI, so existing pension recipients will see their monthly payments increase in January 2026 to account for inflation. New retirees starting CPP at 65 in 2026 will have their benefits calculated using the higher average earnings from 2025, resulting in slightly higher starting benefits compared to 2025 retirees.

What people are saying

Tax season has officially started, and as of today, Canadians can begin to file their 2025 income tax and benefit return online.

The bottom line

The 2026 CRA filing season is defined less by new tax rates and more by the consolidation of digital services. For most Canadian workers, the mechanics haven’t changed — earn, receive slips, file by April 30 — but the tools around filing are shifting decisively online. Physical drop boxes vanish, paper NOAs are gone, and My Account is now the mandatory hub for anyone who wants to check their assessment quickly.

The upside is real: faster processing, pre-populated returns via Auto-Fill, and payment plan access without sitting on hold. The catch is that these efficiencies assume digital access and comfort. Canadians who rely on paper forms or don’t have My Account set up before February will need to act now. For employed Canadians earning $70,000 or $100,000, the effective tax rate is modest relief from inflation-indexed brackets — not a windfall, but not a burden increase either.

For Ontario workers in particular, the deadline is firm: April 30, or 5% penalty on any balance owing. The CRA’s push toward digital-first service means the agency is betting that Canadians will adapt — and most already have, with 93% filing online last year.
