How does a US DTC brand register for Canadian GST/HST as a non-resident seller?

When a US DTC brand must register for Canadian GST/HST

The trigger is the small supplier threshold in the Excise Tax Act: CAD $30,000 in worldwide taxable supplies over the four calendar quarters immediately preceding the current quarter.^[1] Worldwide is the operative word. The threshold is not measured on Canadian sales alone. A brand generating USD $60,000 in US sales has already cleared the combined CAD $30,000 threshold before a single Canadian order ships. The registration obligation exists once the total worldwide figure exceeds CAD $30,000, regardless of how much of that revenue came from Canadian consumers.^[1]

The collection obligation attaches the day after the threshold is exceeded.^[2] Not on the first day of the next quarter. Not on the next filing deadline. The day after. A brand that crosses CAD $30,000 in worldwide taxable supplies on any given day is required to collect and remit GST/HST on Canadian sales starting the following day. The CRA provides a 30-day window from that date to submit Form RC1 without being treated as late for registration purposes, but the collection clock starts on day one.^[2]

Once the application is processed, CRA assigns a Business Number (BN). The BN is a 9-digit identifier; the GST/HST program account carries the designation RT 0001.^[3] Standard Form RC1 applications from non-resident vendors typically process in 4 to 8 weeks.^[3] During that window, the collection obligation already exists. Brands with a clear Canadian revenue trajectory typically submit RC1 before crossing the threshold so the BN arrives close to when collection begins.

The threshold applies with full force to US brands fulfilling exclusively from the US, with no Canadian warehouse, employees, or contractors. Physical presence in Canada is not required to trigger the registration obligation.^[2] The CRA's position is that a non-resident vendor delivering physical goods to Canadian consumers is making taxable supplies in Canada under the Excise Tax Act regardless of where fulfillment originates.

The M&A context surfaces regularly: diligence on a US ecommerce brand frequently flags unregistered Canadian GST/HST exposure as a compliance gap. Back registration with prior period filings, accrued interest on late remittances, and penalties for willful non-compliance represent the cost of that gap. Proactive registration before the threshold is the materially less expensive path.

Standard regime vs. simplified regime: what applies to physical goods sellers

Canada introduced a simplified GST/HST registration for certain non-resident businesses effective July 1, 2021.^[4] The simplified regime is designed for non-resident digital suppliers (streaming services, software, SaaS platforms) and non-resident distribution platform operators facilitating sales by third-party vendors. It is not available to US brands shipping physical goods to Canadian consumers through their own Shopify or Shopify Plus checkout.^[4]

The practical result is that most US DTC brands on Shopify or Shopify Plus use the standard regime, which requires:

1. Register with CRA using Form RC1 (Request for a Business Number and Certain Program Accounts).^[3]
2. Collect GST/HST at checkout on Canadian taxable sales.
3. File GST/HST returns on the CRA-assigned reporting period (annual, quarterly, or monthly).
4. Remit net tax (GST/HST collected minus eligible input tax credits) in CAD.
5. Maintain source documentation supporting every ITC claimed.

The standard regime allows the brand to claim input tax credits (ITCs) on GST/HST paid on Canadian business costs: fulfillment expenses incurred in Canada, returns processed through a Canadian facility, Canadian-based advertising spend, and professional fees paid to Canadian practitioners.^[8] The simplified regime does not permit ITC claims.^[4] For a brand with material Canadian-incurred costs, the difference carries a measurable dollar value.

Form RC1 is submitted to the CRA. Non-resident applicants can use CRA's Business Registration Online portal or submit by fax or mail.^[3] CRA may require supporting documentation from the non-resident applicant, including proof of business incorporation and a description of the commercial activity carried on in Canada.

The US-side compliance chain is a separate workflow. TaxCloud's native Shopify and Shopify Plus integration handles parallel US calculation and filing, including Streamlined Sales Tax (SST) filing across the 23 full member states plus Tennessee as associate, while the brand resources the CRA registration chain separately through a Canadian indirect-tax practitioner or a US firm with Canadian indirect-tax practice.

GST/HST rates by province

Canada's GST and HST structure depends on whether the customer's shipping province participates in the harmonized regime. In the five participating provinces, the provincial and federal components are merged into a single HST rate collected and remitted through the CRA. In non-participating provinces, only the 5% federal GST applies through the CRA registration; provincial taxes in those provinces are administered separately.^[5]

A single CRA GST/HST registration covers the brand's GST and HST obligations in all provinces and territories. For the five participating provinces, the brand collects HST at the applicable rate (13% or 15%) and remits to CRA. For non-participating provinces, the brand collects 5% GST and remits to CRA. The CRA registration does not cover QST or the three provincial sales taxes; those require separate registrations as covered in the final section.

When Shopify Markets routes a Canadian order, TaxCloud's native Shopify and Shopify Plus integration runs the US-side calculation in parallel. The Canadian GST/HST rate in Shopify is governed by the province-specific table above, applied once the brand's CRA-assigned BN is entered in the Shopify tax settings; the two compliance chains operate independently and do not interfere with each other.

Shopify checkout mechanics for Canadian tax collection

Shopify Markets handles province-level tax detection for Canadian orders. When a Canadian shipping address is entered at checkout, Shopify identifies the province and applies the appropriate GST or HST rate from the rate table above.^[6] The configuration requires the brand to enter its CRA-assigned GST/HST registration number in the Shopify admin under Settings > Taxes and duties > Canada.^[6] The registration number format is the 9-digit BN followed by the RT program account identifier (for example, 123456789 RT 0001).

Until the BN is registered in the Shopify admin, Shopify does not collect GST/HST on Canadian orders. This creates a practical gap: the collection obligation exists from the day after the threshold is exceeded, but Shopify cannot collect without the BN configured. Brands whose Canadian revenue is approaching CAD $30,000 should submit Form RC1 before crossing the threshold to minimize the window between obligation and collection.

Canada's customs de minimis threshold is CAD $20.^[7] Shipments at or below this value enter Canada without formal customs assessment of duties or taxes at the border. For a registered brand collecting GST/HST at checkout on every taxable sale, the de minimis does not reduce that collection obligation; checkout collection replaces border-level collection for registered vendors. The de minimis primarily affects unregistered vendors and the administrative burden on individual low-value shipments.

Shipments above CAD $20 are subject to formal customs entry through Canada Border Services Agency (CBSA), which may include import duties depending on the product's tariff classification and Canada-United States-Mexico Agreement (CUSMA) origin rules.^[7] Most US-manufactured goods shipped to Canada qualify for duty-free treatment under CUSMA. Products manufactured outside North America and re-exported from the US to Canada do not receive that treatment and may face Canadian import duties on top of GST/HST.

Filing cadence, remittance currency, and the common mistakes

CRA assigns a reporting period to each GST/HST registrant based on annual taxable supplies from Canadian operations.^[8] The three tiers:

• Monthly: annual taxable supplies exceeding CAD $6 million
• Quarterly: annual taxable supplies between CAD $1.5 million and $6 million
• Annual: annual taxable supplies of CAD $1.5 million or less

A US DTC brand newly registering with CAD $800,000 in annual Canadian sales will typically be assigned an annual or quarterly reporting period. The CRA assignment is not elective. Missing the assigned filing date triggers a late-remittance penalty of 1% per month on the outstanding balance, plus daily compound interest at the prescribed rate.^[8]

Filing is done through CRA's My Business Account portal or by mailing paper Form GST34 (Goods and Services Tax/Harmonized Sales Tax Return for Registrants).^[9] Most brands with material Canadian volume use My Business Account; the paper Form GST34 adds processing time and introduces tracking risk. Remittances through My Business Account can be made by online banking using the CRA's payee code.

Remittances must be in CAD. If the brand's functional currency is USD, the brand converts the remittance amount using the Bank of Canada exchange rate applicable to the filing period.^[8] The methodology must be documented; CRA auditors examine currency conversion records, and using an undocumented or incorrect rate is treated as a filing discrepancy.

Six mistakes US brands make on Canadian GST/HST filings:

1. Filing or remitting in USD. CRA returns or rejects filings denominated in USD. Returns and remittances must be in CAD.
2. Missing the assigned reporting period. The CRA-assigned cadence is not an option the brand can override. A brand that files late because it assumed an annual schedule when CRA assigned quarterly will face penalties on every missed quarterly deadline.
3. Missing input tax credits. Standard regime registrants can claim ITCs on Canadian-incurred GST/HST: fulfillment costs incurred in Canada, returns processed at a Canadian facility, professional fees paid to Canadian practitioners. Most US brands miss this because Canadian-incurred costs are recorded in USD and the link to CRA-recoverable tax is not tracked.
4. Treating the CAD $20 customs de minimis as a GST/HST exemption. The de minimis affects border-level duty and tax assessment on individual shipments; it does not reduce the collection obligation for a registered vendor.
5. Failing to register for Quebec QST. A brand registered for GST/HST but not QST is collecting 5% on Quebec orders when the combined obligation is 14.975% (5% GST plus 9.975% QST).
6. Not evaluating PST registration in BC, Saskatchewan, and Manitoba. Each province imposes provincial sales tax through a separate registration and remittance process.

The multi-province operational pattern: QST and PST beyond GST/HST

The CRA GST/HST registration covers the federal obligation and the HST in the five participating provinces. Brands with material sales into Quebec, British Columbia, Saskatchewan, or Manitoba face additional provincial obligations that run on separate regulatory tracks.

Quebec (QST)

Quebec operates outside the HST framework. The Quebec Sales Tax rate is 9.975%, administered by Revenu Québec, not the CRA.^[10] A brand shipping into Quebec owes both GST (5%, remitted to CRA) and QST (9.975%, remitted to Revenu Québec) on taxable supplies delivered to Quebec addresses. These are filed separately, on separate cadences, through separate portals.

Revenu Québec has extended QST registration requirements to non-resident vendors of physical goods, with the threshold and registration mechanics tied to the brand's Quebec-specific supply volume.^[10] The registration process runs through Revenu Québec's online portal, separate from CRA's Business Registration Online. Confirm the applicable threshold and registration path with Revenu Québec or a Canadian indirect-tax practitioner, as the rules for non-resident physical goods sellers have been updated in recent years.

British Columbia (PST)

BC PST is 7%, administered by the BC Ministry of Finance.^[11] BC has extended PST obligations to non-resident vendors making retail sales to BC consumers. The rules for physical goods sellers differ from BC's PST rules for software and digital services. Brands with regular BC sales volume should confirm registration requirements with a Canadian practitioner and verify the current registration path through the BC Online registry.^[11]

Saskatchewan (PST)

Saskatchewan PST is 6%, administered by Saskatchewan Finance.^[12] Non-resident vendors making retail sales into Saskatchewan are required to register. Registration and filing run through Saskatchewan's eTax Saskatchewan portal.

Manitoba (Retail Sales Tax)

Manitoba's Retail Sales Tax is 7%, administered by the Manitoba Taxation Division.^[13] Non-resident vendors making retail sales in Manitoba register through Manitoba's Tax Administration System.

The operational sequence for a $20-80M DTC brand reaching meaningful Canadian volume:

1. Register for GST/HST with CRA via Form RC1; enter the assigned BN in Shopify Markets.
2. Register for QST with Revenu Québec if shipping material volume into Quebec.
3. Evaluate PST registration in British Columbia, Saskatchewan, and Manitoba based on sales volume into each province.
4. Engage a Canadian indirect-tax practitioner for filing, ITC claims, and multi-province remittance.
5. Run the Canadian filing workflow on a separate calendar from the US compliance workflow; the two operate on different regulatory cadences, different portals, and different currency bases.

The Canadian registration and filing chain runs through CRA, Revenu Québec, and the PST provincial authorities. TaxCloud's native Shopify and Shopify Plus integration handles the parallel US compliance chain: calculation across 13,000+ US jurisdictions through a single API and consolidated SST filing across the 23 full member states plus Tennessee as associate. Keeping the two chains cleanly separated at the operational level is what allows each to run on its own deadline without interference.
