Sole Proprietorship for Ecommerce Sellers in Canada

A sole proprietorship is typically the simplest structure for an ecommerce sole proprietorship in Canada: you sell online under your own legal name or a registered trade name, keep the profit, and report business income on your personal T1 return using form T2125. Because there is no separate legal entity, taxes stay simple — but you also carry the store's debts, refunds and product liability personally.

Many Canadian online sellers — Shopify storefronts, Etsy shops, Amazon and eBay sellers, print-on-demand and digital-product businesses — operate this way, especially in the first few years. This page covers registration, GST/HST, income tax, liability, and when an ecommerce business structure other than a sole proprietorship starts to make more sense.

How an ecommerce sole proprietorship works

The CRA treats your selling activity as self-employment income, whether you ship physical goods, sell digital downloads, or bundle a service with your store. The main features:

• Revenue and expenses are reported on form T2125 and filed with your personal T1 return.
• You can hold a Business Number (BN) and a GST/HST account in your own name or under a registered trade name.
• Net profit is taxed at your personal marginal rate — there is no separate corporate tax rate.
• You are personally responsible for debts, chargebacks, refunds and product liability claims.
• Business losses may generally be applied against other income, subject to CRA rules.

Registering an online store in Canada

Registration is provincial. In most provinces you must register if you carry on business under a name other than your own legal name; if you sell only under your personal name, registration may not be required. You generally register in the province where you operate, though the rules change if you have staff, inventory or fulfilment space elsewhere. See whether you need to register a sole proprietorship and how to register a business name in Canada for the steps.

Separately, you may need a Business Number from the CRA for a GST/HST account, a payroll account if you hire staff, or an import account if you bring goods into Canada. Municipal business licences and zoning rules can also apply when you store inventory or receive customers at home — confirm with your municipality.

GST/HST and sales tax on online sales

GST/HST is usually the largest compliance item for an online store. You register once your revenue exceeds the small supplier threshold; confirm the current amount on the CRA website, since it changes. Once registered, you generally charge tax based on the buyer's location, collect it, and remit it, with a filing frequency the CRA sets based on your revenue.

Quebec administers its own QST, and British Columbia, Saskatchewan and Manitoba levy provincial sales tax — check Revenu Québec or your provincial ministry if you sell to customers there. Online marketplaces sometimes collect and remit tax for you, so confirm who the supplier of record is before assuming you are covered.

Income tax, deductions and recordkeeping

Because there is no separate entity, your net profit flows into your personal return. Deductible costs typically include cost of goods sold, marketplace and payment-processing fees, shipping, packaging, advertising, website and app subscriptions, and a reasonable share of home internet, utilities or storage space used for the business.

Keep records for the period the CRA requires — currently several years after the tax year they relate to; confirm the current rule on canada.ca. As a self-employed individual you generally contribute to CPP on net self-employment income, and EI is not normally available, though self-employed people can opt in to special benefits. If you hire help, see can a sole proprietorship have employees in Canada; contractors you pay may require a T4A slip.

Liability and risk for online sellers

Risk is the main trade-off. As a sole proprietor you are personally responsible for defective products, shipping disputes, chargebacks, refunds, supplier debts and injury claims linked to what you sell. Commercial general liability and product liability insurance can help cover a claim, but insurance does not cap your personal exposure the way incorporation can. Read sole proprietorship liability for a fuller picture of what you are personally responsible for.

When to reconsider your ecommerce business structure

As revenue grows, two questions appear: tax deferral and liability. A corporation may leave more after-tax cash inside the business and separate your personal assets from store risk, but it adds accounting, filing and payroll costs. Compare the options in sole proprietorship vs corporation in Canada before you switch, and note that incorporating later can trigger tax on assets you transfer.

Practical next steps

If you already sell online under your own name, confirm whether provincial registration is required, decide whether to register for GST/HST, and open a separate bank account so business and personal spending stay clean. If you are starting fresh today, begin with the plain-language overview in what is a sole proprietorship, then register only what you actually need.
