Canada Tax Deadlines 2026: CRA, GST/HST, Payroll, Corporate, Provincial, and Local Dates

For Canada, most 2025 individual income tax returns and balances were due April 30, 2026. Self-employed taxpayers usually file by June 15, 2026, but any 2025 balance was still due April 30. Individual instalments for 2026 are March 15, June 15, September 15, and December 15. Regular payroll remitters pay by the 15th of the next month; accelerated remitters pay faster. GST/HST monthly and quarterly returns are generally due one month after the period. Corporations file T2 within six months after year-end, while balances are generally due two or three months after year-end. Canada also has separate Quebec, Alberta, provincial sales/payroll, municipal property, vacancy-tax, import, excise, and Indigenous-tax dates.

A Canada deadline page needs more than a CRA personal-tax calendar. CRA controls federal personal tax, most payroll remittances, GST/HST, T2 administration, trust returns, non-resident withholding, UHT transition rules, excise, luxury tax, and many information returns. CBSA controls commercial import payments through CARM. Revenu Quebec controls Quebec income tax, QST, RL slips, and provincial employer remittances. Alberta administers Alberta corporate income tax. Provinces, territories, municipalities, and participating Indigenous governments add their own date systems.

This is the reusable structure for the top-50-country deadline project: exact national dates where they exist, devolved or subnational calendars where tax powers differ, and local-bill patterns where no country-wide date exists.

Most deadline pages stop at "April 30" or list a few CRA personal dates. That is not enough for a Canadian household, landlord, employer, importer, online seller, corporation, or property investor. A useful Canada page must answer the first deadline quickly, then route the user by taxpayer type, tax account, province, reporting period, and local authority.

These dates were last verified on June 24, 2026. The UHT row is especially important because 2026 law changes make older pages unreliable for 2025 and later years.

Canadian payroll is a frequency problem. A regular employer, quarterly remitter, accelerated remitter, Quebec employer, Ontario EHT filer, and B.C. EHT filer can all have different dates. Annual slips add a second layer because slip filing can be late even if tax was remitted.

Business dates are often anchored to reporting periods and fiscal year-ends rather than a single calendar date. GST/HST, QST, corporation tax, Alberta AT1, Quebec corporate tax, SR&ED, instalments, and annual information returns need separate controls.

These dates are where a generic income-tax calendar usually fails. Importers need CBSA/CARM dates. Excise registrants need their program return periods. Luxury tax changed for aircraft and vessels after November 4, 2025. Federal fuel charge rates are zero from April 1, 2025, with older-period obligations still possible. Digital Services Tax was repealed in 2026.

"Devolved tax dates" in Canada usually means Quebec filing systems, Alberta corporate tax, provincial sales taxes, employer health/payroll taxes, property transfer taxes, vacancy/speculation taxes, resource taxes, and Indigenous-government tax agreements. The key practical point: a CRA date may still apply to one account while another province-specific account has a different deadline.

Local tax dates in Canada are bill-led. Property tax, school/education property tax, vacant-home taxes, accommodation taxes, business licences, signage, parking, utilities, waste, development charges, local improvement charges, and transit or regional levies usually come from a city, municipality, region, or project notice.

Use this matrix to route the full Canada tax taxonomy to the right date owner. It covers personal taxes, payroll, information returns, GST/HST, provincial sales taxes, corporate tax, property taxes, imports, excise, carbon/resource taxes, and Indigenous-government agreements.

First identify the account and authority. A late CRA T1 return, unpaid payroll remittance, missed GST/HST return, late T2 balance, Quebec QST issue, Alberta AT1 problem, CBSA import payment, Toronto property-tax instalment, or Vancouver Empty Homes Tax declaration is handled through a different system. File or pay the missing item first where possible, then review penalty relief, objection, appeal, or payment arrangement options with evidence.

Run this checklist before relying on any Canadian tax due date. It catches the common mistakes that broad "tax calendar" pages miss.

• Identify the account: CRA T1, CRA payroll, GST/HST, T2, trust, UHT, excise, CBSA, Revenu Quebec, Alberta TRA, provincial tax, municipal bill, or Indigenous agreement.
• Confirm the trigger: tax year, fiscal year-end, reporting period, remitter type, import statement, closing date, declaration year, bill date, or permit event.
• Separate filing, payment, instalment, slip, declaration, registration, and notice dates.
• For self-employed individuals, keep April 30 payment separate from June 15 filing.
• For corporations, keep the two-/three-month balance due date separate from the six-month T2 filing date.
• For GST/HST and QST, check filing frequency and fiscal year-end before assuming a calendar quarter.
• For Quebec, check both CRA and Revenu Quebec requirements.
• For property, separate federal UHT, provincial speculation/foreign buyer taxes, municipal vacant-home taxes, and ordinary property tax bills.
• For imports, check the CARM statement of account, broker workflow, and monthly CBSA due date.
• Save confirmations, notices of assessment, municipal bills, property declarations, CARM statements, and remittance vouchers.

I looked for a current official or institutional video that explains the full Canada tax deadline calendar across CRA personal tax, payroll, GST/HST, corporate tax, provincial taxes, local taxes, CBSA imports, excise, and specialty taxes. No suitable single official embeddable video was found.

Because the reliable material for this topic is in official CRA, CBSA, Revenu Quebec, provincial, and municipal guidance, this article does not embed a low-trust creator video just to fill a media slot.

This CalculatorWallah guide was written as a source-backed Canada tax deadline reference, not as legal or tax advice. It exists because users searching for "Canada tax deadlines 2026" need more than an April 30 answer: they need CRA, CBSA, Quebec, Alberta, provincial, municipal, property, import, payroll, GST/HST, corporate, specialty-tax, and Indigenous-tax timing in one usable map.

Methodology: we started with the supplied Canada tax taxonomy, mapped each tax type to the authority that controls its deadline, then verified material dates against official CRA, CBSA, Revenu Quebec, Alberta, Ontario, British Columbia, Toronto, Vancouver, and Indigenous-tax sources. The page was last updated on June 24, 2026.

Scope limit: Canadian deadlines can change because of weekend/holiday adjustments, fiscal years, reporting periods, remitter categories, CARM cycles, province-specific rules, municipal billing, property events, legislative transitions, and account notices. Use this article as the planning structure, then verify the exact account date on the official portal before filing or paying.
