GST/HST return and payment — monthly filers

Goods and services tax / harmonized sales tax (GST/HST) · Monthly · return filing

last day of the month after the month ends Verified 2026-10-14

Who files: GST/HST registrants with annual taxable supplies over CAD 6,000,000 (assigned monthly), and any smaller registrant that elects monthly filing
Notes: File and pay by the end of the following month — the CRA's own example puts a July period at 31 August. A return is required for every month, including months with no sales and no tax to remit. The September 2026 return moves to Monday 2 November because 31 October is a Saturday. Most registrants must file electronically. Québec businesses whose GST/HST is administered by Revenu Québec follow its schedule, which put the November 2026 deadline at 5 January 2027.

GST/HST return and payment — quarterly filers

Goods and services tax / harmonized sales tax (GST/HST) · Quarterly · return filing

last day of the month after the quarter ends Verified 2026-10-14

Who files: GST/HST registrants with annual taxable supplies over CAD 1,500,000 up to CAD 6,000,000 (assigned quarterly), and smaller registrants that elect quarterly filing; quarters follow the registrant's fiscal year
Notes: Quarterly filers have until the last day of the month after the quarter: a quarter ending 31 March is due 30 April. The dates shown assume a 31 December year-end; a business with another year-end has quarters that close in different months, with the same one-month gap. Weekends push the deadline out — the fourth quarter of 2026 is due Monday 1 February 2027 — and the CRA also accepts the Tuesday after the Civic Holiday outside Québec, for instance 3 August 2027 for the second quarter.

Goods and services tax / harmonized sales tax (GST/HST) · Annually · return filing

31st March each year Verified 2026-10-14

Who files: Annual filers (annual taxable supplies of CAD 1,500,000 or less, unless they elect a shorter period) with a fiscal year ending 31 December, other than sole proprietors with business income and listed financial institutions
Notes: Corporations and other annual filers with a calendar fiscal year file and pay the balance by 31 March — Wednesday 31 March 2027 for 2026. For an annual filer this is the only return of the year. If you owed CAD 3,000 or more in net tax, quarterly instalments are due during the year as well, and the 31 March payment settles whatever they did not cover.

within 3 months of the end of the fiscal year Verified 2026-10-14

Who files: Annual filers whose fiscal year ends on a date other than 31 December (listed financial institutions excepted)
Notes: An annual filer whose year ends in any other month has three months after the year-end: the CRA's example is a 31 August year-end due 30 November. A sole proprietor with a non-calendar year is on this three-month rule too, because the 15 June concession needs a 31 December year-end.

15th June each year Verified 2026-10-14

Who files: Individuals (sole proprietors) who file GST/HST annually, have a 31 December fiscal year-end and had business income for income-tax purposes that year
Notes: A self-employed individual gets until 15 June to file the year's return — Tuesday 15 June 2027 for 2026 — matching the income-tax filing date. The extension covers the paperwork only: the tax is due six weeks earlier, on 30 April, and interest runs on anything paid after that.

Who files: The same sole proprietors who file by 15 June: individuals with business income, a 31 December year-end and annual GST/HST filing
Notes: Pay the year's net GST/HST by 30 April even though the return can wait until June. In 2028, 30 April is a Sunday, so the payment is on time on Monday 1 May. A sole proprietor who also pays instalments has two payments on the same day: the balance for last year and the first instalment for this one.

Who files: Annual filers whose net tax was CAD 3,000 or more for the previous fiscal year and is CAD 3,000 or more for the current one; dates shown are for a 31 December year-end
Notes: An annual filer that owes CAD 3,000 or more pays a quarter of its expected tax four times a year, on 30 April, 31 July, 31 October and 31 January for a calendar year. Below CAD 3,000 in either year there are no instalments. The CRA counts a payment as on time if it is received, or postmarked, by the next business day after a weekend or holiday, so the October 2026 instalment can be paid on Monday 2 November.

Simplified GST/HST return and payment — non-resident digital suppliers and platform operators

Goods and services tax / harmonized sales tax (GST/HST) — simplified registration · Quarterly · return filing

last day of the month after the quarter ends Verified 2026-10-14

Who files: Non-resident vendors of digital products and services, and distribution and accommodation platform operators, registered under the simplified GST/HST regime (not carrying on business in Canada)
Notes: Simplified registrants always report by calendar quarter, online only, and pay by the return's due date: 30 April, 31 July, 31 October and 31 January. There is no monthly or annual option. A due date on a weekend or federal holiday moves to the next business day, so the third quarter of 2026 is due Monday 2 November and the fourth quarter Monday 1 February 2027.

GST/HST registration — 30-day window after ceasing to be a small supplier

Goods and services tax / harmonized sales tax (GST/HST) · One-off · registration

within 29 days of the first taxable supply made in Canada other than as a small supplier Verified 2026-10-14

Who files: Persons making taxable supplies in Canada whose worldwide taxable supplies (with associates) exceed CAD 30,000 in a single calendar quarter or over four consecutive quarters (CAD 50,000 for public service bodies); taxi and ride-sharing operators regardless of revenue
Notes: Apply before the 30th day after your first taxable sale made other than as a small supplier — in the CRA's words, within 29 days. Crossing CAD 30,000 in a single quarter ends small-supplier status on the very sale that crosses it, and GST/HST is chargeable on that sale; crossing it only over four quarters ends the status at the end of the month after that quarter. Taxi and ride-sharing drivers must register from their first fare.

Notes: Unlike the regular 30-day window, there is no grace period here: the application, made online, is due on or before the first day you are required to be registered, which is the day your sales to Canadian consumers over the past 12 months pass CAD 30,000.

QST return and remittance — monthly filers (Revenu Québec)

Québec sales tax (QST) · Monthly · return filing

last day of the month after the month ends Verified 2026-10-14

Who files: QST registrants on a monthly filing frequency — assigned when total annual taxable sales made in Canada exceed CAD 6,000,000, or elected; the frequency must match the registrant's GST/HST frequency
Notes: The QST is reported to Revenu Québec, usually on the same return as the GST/HST and with the same frequency, and the amount owing is remitted when the return is filed. Revenu Québec publishes the exact dates each year: the last day of the next month, moved to the next business day when it is closed. Its offices close from 24 December to early January, so the November 2026 return is due 5 January 2027, later than shown here.

Who files: QST registrants on a quarterly filing frequency — total annual taxable sales in Canada over CAD 1,500,000 up to CAD 6,000,000, or elected; quarters follow the fiscal year shared with the GST/HST
Notes: Quarterly QST returns follow the GST/HST quarters exactly, because Revenu Québec requires the same fiscal year for both taxes. For a calendar year the third quarter of 2026 is due Monday 2 November and the fourth Monday 1 February 2027. A fiscal quarter ending in November falls due in the year-end closure, which Revenu Québec set at 5 January for 2026.

QST annual return and remittance — 31 December year-end

Québec sales tax (QST) · Annually · return filing

Who files: Annual QST filers (total annual taxable sales in Canada of CAD 1,500,000 or less) with a 31 December fiscal year, other than individuals with business income and listed financial institutions
Notes: Revenu Québec's schedule puts the 2026 annual return for corporations at 31 March 2027. With another year-end the return is due three months after it, so a 30 September year-end ran into the January closure and was due 5 January 2027. Listed financial institutions have six months instead.

Who files: Annual QST filers whose net QST expected for the current year and paid for the previous year are each CAD 3,000 or more; dates shown are for a 31 December year-end
Notes: Revenu Québec applies the GST/HST instalment test to the QST separately: CAD 3,000 or more of net QST this year and last means four instalments, each due by the last day of the month after a fiscal quarter. Payments of CAD 10,000 or more must be made electronically. The annual return then reconciles the instalments against the tax actually owed.

Notes: Specified-system registrants report each calendar quarter online through My Account for suppliers outside Québec, and file and pay by the last day of the following month. Revenu Québec does not say whether this date moves off a weekend, so treat a Saturday or Sunday as no extension: the third quarter of 2026 is due Saturday 31 October, so file by Friday the 30th, and the fourth quarter's Sunday 31 January 2027 deadline means paying by Friday 29 January.

QST registration — general system

Québec sales tax (QST) · One-off · registration

Who files: Persons making taxable supplies in Québec whose worldwide taxable supplies (with associates) exceed CAD 30,000 in a calendar quarter or over four consecutive quarters; retail tobacco vendors and vendors of new tyres and of new or used road vehicles regardless of revenue
Notes: You must apply for QST registration before you make your first taxable supply in Québec other than as a small supplier. That is stricter than the GST, which allows until the 30th day after that supply, so a business crossing CAD 30,000 can be late for the QST while still in time for the GST. Some sellers — of tobacco at retail, new tyres, and new or used road vehicles — must register for the QST whatever their sales.

Canada's federal GST/HST return and its payment are due together, one month after each monthly or quarterly period ends; in practice both the CRA and Revenu Québec treat that as the last day of the following month. Annual filers have three months, or until 15 June (paying by 30 April) for sole proprietors with a 31 December year-end. The CRA accepts a return or payment on the next business day when the due date is a Saturday, Sunday or CRA public holiday. In Québec, Revenu Québec collects the Québec sales tax (QST) and, for most businesses, the GST/HST too, on the same return and the same schedule; its year-end office closures can push a 31 December deadline into early January. There is no separate annual reconciliation return for monthly or quarterly filers. Not covered here: the provincial sales taxes of British Columbia, Saskatchewan and Manitoba, which have their own returns, and GST on imports, which is paid to the Canada Border Services Agency.

What this calendar does not list

Not applicable Recapitulative listing — Canada has no recapitulative or sales listing: neither the CRA's GST/HST registrant guide (RC4022) nor Revenu Québec's GST/HST and QST reporting pages describe a periodic listing of a registrant's supplies (checked 2026-10-14). The federal platform information returns are suspended until further notice; Québec's annual platform information returns are shown separately.
Not applicable E-invoicing / e-reporting cycle — There is no federal e-invoicing or transaction-reporting mandate; the CRA requires electronic filing of returns, which is a format rule, not a reporting cycle. Québec's mandatory billing for restaurants, bars and paid passenger transport transmits each transaction as it happens, so it fixes no submission cadence.
Not yet covered Periodic return — Not yet covered: the provincial sales taxes administered by British Columbia (PST), Saskatchewan (PST) and Manitoba (RST), which have their own returns and due dates; GST/HST on imports, which is billed and collected by the Canada Border Services Agency; excise duty on beer, which falls under the older Excise Act rather than the Excise Act, 2001; and Revenu Québec's notice for operators of storage services in Québec (form VD-477.18.6-V).

About this calendar

Which Canada tax deadlines does this calendar cover?

21 recurring indirect-tax obligations — Goods and services tax / harmonized sales tax (GST/HST), Québec sales tax (QST) and Excise duty (Excise Act, 2001) returns, payments and related filings — each with the due-date rule, who must file, and the official source that states the deadline. Direct-tax, payroll and company-registry deadlines are out of scope.

How current are these due dates?

Every obligation carries the date it was last verified against its official source (newest: 2026-10-14). Law-change dates come from the weekly Last Week in Taxes scan and link to their full change records.

Do the dates account for weekends and public holidays?

No — the calendar shows the statutory due date. Where the authority shifts deadlines falling on non-working days, the obligation notes say so. Confirm against the linked official source before relying on a date.
