The digital economy has transformed how Canadians buy and sell goods, but GST/HST obligations remain a crucial consideration for online businesses. Whether you’re selling handmade crafts on Etsy, running a Shopify store, or leveraging Amazon’s marketplace, understanding your tax responsibilities ensures compliance while avoiding costly penalties.
Canada’s tax system distinguishes between marketplace facilitators (platforms that process payments and facilitate transactions) and independent sellers who manage their own sales channels. Since July 2021, major platforms have taken on new responsibilities under the CRA’s digital economy rules, fundamentally changing how HST applies to online sales. This comprehensive guide clarifies your obligations, platform-specific requirements, and practical steps to maintain compliance in Canada’s evolving e-commerce landscape.
Do You Need to Charge HST on Online Sales?
Your obligation to charge HST on online sales depends primarily on your annual revenue and registration status, not the sales channel you use. The CRA requires mandatory HST registration once your worldwide taxable supplies exceed $30,000 over four consecutive calendar quarters, regardless of whether sales occur online, in-person, or through multiple channels.
Mandatory registration triggers:
- Total taxable sales exceed $30,000 in the last four quarters
- Single calendar quarter sales exceed $30,000
- You’re already registered for HST (must charge on all taxable sales)
- You operate as a taxi or rideshare business (no threshold)
Online sales count toward this threshold exactly like physical sales. If you sell $20,000 through your Shopify store and $15,000 at craft fairs, your combined $35,000 triggers mandatory registration. The clock starts ticking from the moment you exceed the threshold—you have 29 days to register and must begin collecting HST immediately.
Voluntary registration benefits:
Small suppliers below the $30,000 threshold can voluntarily register to claim input tax credits on business expenses. This particularly benefits e-commerce businesses with significant upfront costs for inventory, website development, or marketing. Voluntary registrants must charge HST on all taxable sales, potentially affecting price competitiveness against non-registered sellers.
The HST rate you charge depends on your customer’s location, not your business address. Ontario customers pay 13% HST, while Prince Edward Island residents pay 15%. For detailed provincial rates and rules, consult our guide on HST filing requirements by province.
How Marketplace Platforms Handle HST
Different e-commerce platforms handle HST collection in fundamentally different ways, creating confusion for sellers navigating multiple channels. Understanding each platform’s approach ensures proper compliance and prevents double taxation or missed obligations.
Shopify: Full Seller Responsibility
Shopify operates as a commerce platform rather than a marketplace facilitator, meaning sellers retain complete responsibility for HST collection and remittance. The platform provides tools to automate tax calculations but doesn’t remit taxes on your behalf.
Setting up HST in Shopify:
- Navigate to Settings → Taxes and duties
- Enter your HST registration number
- Configure tax rates for each province
- Set product tax categories (taxable, exempt, zero-rated)
- Enable automatic tax calculations at checkout
Shopify’s Canadian tax configuration automatically applies correct provincial rates based on shipping addresses. However, you must manually remit collected taxes to the CRA through regular HST returns. Track your tax collected through Shopify’s Finance → Taxes report, which provides detailed breakdowns for filing purposes.
Amazon: Marketplace Facilitator Model
Amazon operates as a marketplace facilitator in Canada, collecting and remitting HST on behalf of third-party sellers for orders fulfilled by Amazon (FBA) or where Amazon processes payments. This simplified approach reduces administrative burden but requires understanding which transactions Amazon handles.
Amazon’s HST responsibilities include:
- Collecting HST on FBA sales to Canadian customers
- Remitting collected taxes directly to the CRA
- Providing tax invoices to customers
- Issuing annual tax summaries to sellers
However, sellers remain responsible for HST on merchant-fulfilled orders where they handle payment processing independently. The Amazon Seller Central tax settings must accurately reflect your registration status to ensure proper tax collection on all order types.
Etsy: Hybrid Approach
Etsy implemented marketplace facilitator rules for Canadian sellers, collecting and remitting HST on most transactions. However, the platform’s approach varies based on seller location and transaction type, creating complexity for multi-channel sellers.
Etsy’s HST collection covers:
- Sales to Canadian buyers (automatic HST collection)
- Digital downloads to Canadian customers
- Etsy Payments transactions (platform remits to CRA)
Sellers must still register for HST if exceeding the $30,000 threshold across all channels, as Etsy sales count toward your total taxable supplies. The platform’s tax collection policy details specific scenarios and seller responsibilities. Review your Etsy Finances → Legal and tax information section to verify correct tax settings.

How to Register and File as an E-Commerce Seller
E-commerce sellers follow standard HST registration and filing procedures, with some unique considerations for online sales tracking and multi-channel operations. Proper setup from the start prevents compliance issues as your business scales.
Registration process for online sellers:
- Apply for a Business Number: Register online through the CRA Business Registration portal or call 1-800-959-5525
- Obtain HST account: Select “GST/HST” during registration, providing business details and expected revenue
- Configure e-commerce platforms: Add your HST number to all selling platforms
- Set up accounting systems: Implement software to track multi-channel sales and tax collected
- Establish filing schedule: Most e-commerce sellers file quarterly unless annual revenue exceeds $1.5 million
Example: Shopify seller with $40,000 annual sales
Sarah operates a Shopify jewelry store with $40,000 in 2024 sales. She exceeded the $30,000 threshold in September and registered for HST in October. Her obligations include:
- Collecting 13% HST on Ontario sales, 15% on Maritime sales
- Filing quarterly HST returns (due one month after quarter-end)
- Claiming input tax credits on business expenses
- Maintaining records for six years
Sarah’s Q4 2024 HST return shows $1,300 collected and $400 in input tax credits, resulting in $900 remittance due by January 31, 2025. She files electronically through NETFILE following CRA deadlines and maintains detailed transaction records from Shopify’s reporting tools.
HST on International Sales and Dropshipping
International e-commerce transactions follow specific HST rules that differ significantly from domestic sales. Understanding these distinctions helps optimize pricing strategies while maintaining compliance with Canadian tax obligations.
Exports (Sales to Non-Canadian Customers):
Sales to customers outside Canada are generally zero-rated, meaning you charge 0% HST but can still claim input tax credits on related expenses. This applies to physical goods shipped internationally and most digital services consumed outside Canada.
Zero-rating requirements:
- Maintain proof of export (shipping documents, customs forms)
- Verify customer’s non-Canadian address
- Document delivery outside Canada
- Keep records demonstrating export status
Dropshipping considerations:
Dropshipping arrangements where inventory ships directly from suppliers to customers create complex HST scenarios. The CRA’s drop-shipment rules determine tax obligations based on registration status, shipment origin, and customer location.
If your supplier and customer are both in Canada, you generally must charge HST even if goods never physically pass through your possession. International dropshipping from foreign suppliers to Canadian customers may trigger import duties and HST at the border, affecting final customer pricing.
Fulfillment centers and inventory location:
Storing inventory in Canadian fulfillment centers, including Amazon FBA warehouses, creates permanent establishment issues affecting tax obligations. Inventory location doesn’t change your HST registration requirements but impacts place of supply rules for determining applicable tax rates.
Common Mistakes to Avoid
E-commerce sellers frequently encounter HST compliance issues that result in penalties, interest charges, or competitive disadvantages. Learning from common mistakes helps establish robust processes from the start.
1. Delayed Registration
Many sellers wait until year-end to evaluate the $30,000 threshold, missing the 29-day registration deadline. Monitor sales monthly and project annual revenue to anticipate registration requirements. Early voluntary registration may provide advantages through ITC claims.
2. Incorrect Provincial Rates
Applying your home province’s rate to all sales is a critical error. E-commerce platforms must calculate taxes based on customer delivery addresses. An Ontario-based seller shipping to Nova Scotia charges 14% HST, not Ontario’s 13%. Configure tax settings correctly across all platforms to ensure accurate collection.
3. Platform Remittance Confusion
Assuming marketplace facilitators handle all tax obligations leads to compliance gaps. Even when Amazon or Etsy collects HST on your behalf, you must still register if exceeding thresholds, file returns for other sales channels, and track total taxable supplies across all platforms.
4. Poor Record Keeping
Digital sales require meticulous documentation for CRA audits. Maintain transaction records, tax collected reports, customer locations, and platform statements for six years. Cloud-based accounting software integrating with e-commerce platforms simplifies compliance and provides audit trails.
5. Ignoring Exempt Items
Not all online sales are taxable. Understanding HST-exempt items prevents overcharging customers and ensures competitive pricing. Basic groceries, prescription medications, and certain medical devices remain exempt whether sold online or in-store.
FAQ Section
Do I need to charge HST on digital products sold on Etsy?
Yes, digital products sold to Canadian customers through Etsy are subject to HST. Etsy automatically collects and remits the appropriate provincial HST rate based on the buyer’s location. However, you must still track these sales toward your $30,000 registration threshold and may need to register for HST if selling through multiple channels.
How do I set up HST collection in Shopify?
Access Settings → Taxes and duties in your Shopify admin, enter your HST registration number, and enable automatic tax calculations. Configure tax rates for each Canadian province, classify products as taxable or exempt, and activate tax-inclusive pricing if desired. Shopify calculates taxes at checkout but doesn’t remit them—you must file HST returns and remit collected taxes yourself.
Does Amazon collect HST automatically?
Amazon automatically collects and remits HST for Fulfillment by Amazon (FBA) orders and transactions where Amazon processes payments. For merchant-fulfilled orders with independent payment processing, sellers remain responsible for HST collection and remittance. Verify your tax settings in Seller Central and understand which transactions Amazon handles versus your responsibilities.
Navigate E-Commerce Taxes with Confidence
Successfully managing HST obligations as an e-commerce seller requires understanding platform-specific rules, maintaining accurate records, and staying current with evolving digital economy regulations. While marketplace facilitators have simplified some aspects of tax compliance, sellers retain ultimate responsibility for registration, filing, and remittance across all sales channels.
Start by accurately tracking sales across all platforms, register promptly when approaching thresholds, and implement robust accounting systems that integrate with your e-commerce tools. Regular monitoring and professional guidance ensure compliance while maximizing available input tax credits.
