A seller who has never reported marketplace income, or who reports a smaller number than the platform actually paid out, is used to thinking of that gap as invisible. Under Canada’s digital platform reporting rules, it is not. Amazon, Etsy, Shopify (where applicable), and other qualifying platforms now collect seller information and report annual sales activity directly to the CRA. The platform’s own numbers, not just the seller’s return, are the CRA’s starting point for verification.
What the Rules Require
Canada implemented the OECD’s Model Reporting Rules for digital platforms, referred to domestically as the Reportable Platform Sellers rules, effective for the 2024 calendar year and reported for the first time in early 2025. A platform that meets the definition of a reportable platform operator must collect identifying information from sellers using its marketplace, and must report specified transaction data annually to the CRA.
The obligation sits with the platform, not the seller. A seller does not file this report. What changes for the seller is that a third-party record of their sales activity now reaches the CRA independently of whatever the seller reports on their own return.
What Gets Collected and Reported
Platform operators are required to collect and verify seller identifying information, including legal name, primary address, business registration or tax identification number (SIN or business number), and, where applicable, GST/HST or QST registration number.
On the transaction side, platforms report the total consideration paid or credited to the seller during the calendar year, the number of relevant transactions, and any fees, commissions, or taxes withheld by the platform. For sellers with multiple storefronts or accounts on the same platform, reporting is generally tied to the seller’s verified identity, not to each individual account.
This is a parallel structure to the T5001-style third-party information reporting the CRA already uses in other contexts: the CRA receives the data whether or not the taxpayer’s own return matches it.
Who Is Covered
The rules apply to a broad definition of platform, covering marketplaces that facilitate the sale of goods, services, and certain personal services, subject to relevant thresholds and exclusions built into the framework. Amazon and Etsy are treated as reportable platform operators for goods sold through their marketplaces. Shopify’s position depends on the specific service used: a seller running an independent Shopify storefront is not using a third-party marketplace in the same sense, but Shopify features that route payments or facilitate marketplace-style transactions can bring specific activity into scope. Walmart Marketplace and eBay fall under the same reportable platform operator framework as Amazon and Etsy for third-party marketplace sales.
A seller using multiple platforms should not assume that only the largest platform is reporting. Each qualifying platform operator has an independent reporting obligation.
What This Means for a Seller’s Return
The practical effect is straightforward: the CRA can compare the total activity reported by a platform against the income a seller reports on their T2125 or T2. A material gap between the two, particularly a seller reporting materially less income than the platform reported paying out, is now a matching-based flag rather than something that depends on a manual audit selection.
This does not mean gross platform payout equals taxable income. Amazon FBA True Profitability and Returns, Refunds, Chargebacks, and Reimbursements for E-Commerce Sellers cover why the number on a platform’s payout report is not the number that belongs on a tax return. Fees, refunds, chargebacks, and reimbursements all separate gross platform activity from net taxable income. A seller who reports net income correctly, but far below the platform’s reported gross figure, still needs records that reconcile the difference in case the CRA asks. Reporting a defensible net number is not the same as reporting a number that looks unrelated to what the platform reported.
Reconciliation Is the Practical Response
The response to platform reporting is not a new filing obligation. It is making sure the seller’s own books can reconcile to the platform’s reported figures if asked. Amazon Settlement Report Reconciliation and Month-End Close Checklist for Marketplace Sellers describe the reconciliation habits that make this straightforward: matching platform settlement or payout totals against recorded gross sales, fees, and refunds on a recurring basis, rather than reconstructing a year of activity after a CRA letter arrives.
A seller who has been under-reporting, whether through a missed platform, an early sole proprietorship year with no return filed, or income reported on a cash basis that missed year-end payouts, should treat this as a reason to reconcile prior years before the CRA’s own matching process raises the question. Rebuilding records against platform settlement history and, where the gap is material, the CRA’s Voluntary Disclosures Program are the relevant paths depending on how far behind the records are.
Common Mistakes
Assuming reporting only applies to “big” sellers. The rules are not built around a large seller carve-out in the way some income tax thresholds are. A seller with modest volume on a reportable platform is still subject to the same data collection and reporting by that platform.
Confusing platform reporting with GST/HST marketplace facilitator collection. These are separate mechanisms. Marketplace facilitator rules determine who collects and remits GST/HST on a sale. Digital platform reporting rules determine what income data the CRA receives about the seller. A platform can be a GST/HST deemed supplier and a reportable platform operator at the same time, but they answer different questions.
Not updating identity information requested by a platform. A platform that cannot verify a seller’s required identifying information may be required to restrict payouts until the information is provided. Ignoring a platform’s data collection request is not a way to opt out of the reporting obligation; it risks a payout hold instead.
Treating gross payout and taxable income as the same number when reconciling. The CRA’s comparison starts with the platform’s reported gross figures. A seller’s job is to be able to explain the path from that gross figure to the net income actually reported, not to make the two numbers identical.
