E-commerce isn't just selling online—it's navigating a maze of VAT rules, cross-border regulations, and platform-specific requirements that would make any traditional business owner's head spin. If you're selling products or services online from the Czech Republic, specialized tax guidance isn't a luxury—it's a necessity.
VAT for Cross-Border Sales
Selling to EU consumers triggers VAT obligations in customer countries once you exceed distance selling thresholds (now just €10,000 combined EU-wide). The One-Stop-Shop (OSS) system simplifies reporting, but understanding which rate applies to each sale requires expertise.
Non-EU sales follow different rules entirely—often no VAT on exports, but with documentation requirements to prove it.
Marketplace Facilitator Rules
Platforms like Amazon, eBay, and Etsy may handle VAT collection and remittance for certain transactions under "deemed supplier" rules. But here's the complexity: understanding when the platform is responsible versus when you remain liable prevents double taxation—or unexpected tax bills.
The rules depend on where goods are located, where they're shipped, and the platform's specific arrangements.
Digital Services VAT
Digital products and services follow special VAT rules based on customer location. Software, e-books, online courses, and digital downloads each have specific treatment. Proper customer location tracking and rate application are essential for compliance.
Selling a PDF guide to someone in Germany? That's German VAT rates, not Czech.
Inventory and Cost of Goods
Proper inventory valuation directly affects your taxable profit. Track purchase costs, shipping to your location, customs duties, and storage expenses. Understanding first-in-first-out versus weighted average methods impacts your tax calculation.
International Shipping Deductions
Shipping costs to customers, packaging materials, customs fees, and fulfillment services (like FBA fees) are deductible business expenses. Maintain detailed records linking expenses to specific sales or time periods for audit defense.
Currency Conversion Issues
Selling in foreign currencies requires proper conversion to CZK for tax reporting. Use consistent exchange rate methodologies and document rates applied. Currency gains or losses on conversion may have their own tax implications.
Inconsistent conversion methods invite audit questions.
Platform Fees and Commissions
Marketplace commissions, payment processing fees, advertising costs on platforms, and subscription fees for selling tools are all deductible. Categorize these expenses correctly for accurate profit calculation—they can represent a significant portion of your costs.
Returns and Refund Handling
Product returns affect both revenue and VAT calculations. Implement systems to track returns, process refunds correctly, and adjust tax reporting for returned merchandise. Cross-border returns add another layer of complexity.
Dropshipping Special Considerations
Dropshipping creates unique tax situations where goods never physically pass through your possession. VAT liability depends on supplier location, customer location, and your contractual relationship with the supplier. Get this wrong and you face significant unexpected liabilities.
We've seen dropshippers hit with five-figure VAT bills because they didn't understand the rules. Don't become a cautionary tale.
