The platform’s complexity creates unique compliance risks: Key Amazon Accounting Challenges: FBA fee structures include variable closing fees, storage costs, and long-term storage penalties that change quarterly Marketplace Facilitator Tax collection began in 2021, but sellers remain responsible for non-marketplace sales and wholesale orders Multi-country inventory triggers customs valuation and transfer pricing considerations Advertising cost of sales (ACoS) must be allocated across SKUs for accurate profitability analysis Critical Compliance Requirement: Amazon’s data retention policies provide only 24 months of transaction history. Professional accounting services must implement automated backup systems to preserve records for CRA’s six-year audit requirement. Tax Accounting in E-commerce: GST/HST Compliance Tax accounting in e-commerce represents the most complex aspect of Canadian online retail financial management. The CRA has intensified enforcement, with enhanced data- sharing arrangements with payment processors and marketplaces to identify non- compliant sellers. GST/HST Registration and Filing Obligations Mandatory Registration Threshold: $30,000 CAD in taxable revenues within any 12-month period triggers GST/HST registration requirement. This includes: Direct website sales Marketplace transactions (even if tax is collected by the platform) Digital product revenues Service commissions Filing Frequency Based on Revenue: Annual filing: Under $1.5 million CAD Quarterly filing: $1.5 million to $6 million CAD Monthly filing: Over $6 million CAD Electronic Filing Mandate: Since 2024, electronic filing is mandatory for all businesses with limited exceptions, eliminating paper-based submissions. 5/7
