Cross-border e-commerce represented by Amazon, independent websites and TikTok Shop has developed rapidly. However, sellers commonly face problems such as ambiguous domestic and overseas entity structures, insufficient documents for export tax rebates/ exemptions, omitted overseas VAT/GST declarations, non-compliant related-party pricing, unclear fund collection and profit repatriation routes.
Cross-border tax planning shall form a closed-loop system covering domestic export, overseas turnover tax, platform funds, related-party transactions and profit distribution. The fundamental principles are genuine transactions, complete documents and truthful declarations. It is illegal to replace compliant operations with fictitious transactions, individual fund splitting or artificial profit shifting at low prices.
1. Entity Structure: Align with Platform Rules and Business Substance
A typical structure for small and medium-sized sellers: domestic entities are responsible for procurement, supply chain, customs declaration and export tax rebates; Hong Kong or other overseas entities handle platform collection, overseas marketing, brand ownership and regional management. Structure design shall take into account platform requirements, fund routes, brand ownership, staffing, tax treaties and profit repatriation needs.
Hong Kong adopts the territorial source principle of taxation. Tax liabilities are determined by income sources, business substance, Foreign-Sourced Income Exemption (FSIE) and case rulings by the Inland Revenue Department. Overseas collection companies with actual fund flows, contracts or business activities shall not file nil returns for a long time. They must complete bookkeeping, audit, annual inspection and tax filings per local rules.
2. Export Tax Rebates & Document Management: Domestic Compliance Foundation
Cross-border e-commerce enterprises shall distinguish different policy regimes, including general export tax rebates/exemptions, cross-border e-commerce export exemption, market procurement trade, 9610, 9710 and 9810 overseas warehouse export. Eligibility for tax rebates depends on export modes, valid input invoices, customs data, foreign exchange settlement and requirements of competent tax authorities.
The 9810 overseas warehouse regime has implemented the mechanism of "tax rebate upon departure, final settlement after sales" to optimize cash flow. Enterprises must ensure consistency among orders, customs declarations, logistics documents, warehouse records, platform sales data and settlement vouchers. Illegal practices such as fake export declarations, falsified goods values, forged logistics documents and repeated rebate applications will trigger tax, customs and foreign exchange risks.
3. Overseas VAT, GST & Sales Tax: High-risk Areas
The EU has launched the OSS one-stop declaration system for e-commerce VAT, with unified threshold rules for intra-EU distance sales. Old understanding of separate thresholds among member states is no longer applicable. For non-EU sellers, platform withholding, import links, overseas inventory and cross-border sales, conduct assessment on tax registration, filing and OSS/IOSS application item by item.
Enterprises using overseas warehouses shall focus on local VAT registration, input VAT deduction, output tax declaration, platform withholding and inventory transfer rules. Markets in Southeast Asia, the UK, the US and other regions have independent GST, VAT or sales tax regulations, which cannot be handled simply following domestic Chinese practices.
4. Related-party Transactions & Profit Allocation: Follow Arm’s Length Principle
Many sellers supply goods to overseas collection entities at low prices, or adjust profits via brand royalties, service fees and technical support fees. If pricing deviates significantly from market levels and overseas entities lack matching personnel, assets, functions and risk-bearing capacity, tax authorities will deem it artificial profit shifting.
Enterprises shall formulate reasonable gross profit margins and related-party policies based on third-party prices, platform sales data, logistics costs, advertising expenses, brand contribution and after-sales liabilities. Retain procurement contracts, sales reports, advertising records, logistics bills, expense allocation sheets and pricing explanations. Large-scale enterprises shall assess obligations to prepare transfer pricing contemporaneous documents.
5. Fund Collection & Profit Repatriation: Based on Genuine Transactions
After platform funds are collected into overseas accounts, repatriation can be conducted via trade payment, service fees, royalties, dividends or shareholder transactions. Every route must be supported by genuine transactions, valid contracts, reasonable pricing and complete tax documents. It is prohibited to use underground banks, individual annual USD 50,000 settlement quotas or fictitious service contracts to process corporate funds.
Large cross-border e-commerce enterprises may consider cross-border cash pools, overseas reinvestment or regional headquarters, while complying with foreign exchange, tax, CFC, transfer pricing and beneficial ownership rules.
