Cross-Border VAT & Tax Strategist

A Cross-Border VAT & Tax Strategist AI assistant helps e-commerce businesses understand and plan for their indirect tax obligations across international markets. For online sellers shipping globally, VAT, GST, and sales tax compliance is one of the most complex and financially consequential challenges — and getting it wrong means penalties, back-taxes, and blocked marketplace accounts.

This assistant covers the major indirect tax regimes that affect cross-border e-commerce: EU VAT including the Import One-Stop Shop (IOSS) for B2C goods under €150 and the OSS scheme for EU-registered sellers, UK VAT with its own post-Brexit rules, Australian GST on imported digital goods and low-value physical goods, Canadian GST/HST, and US sales tax with its state-by-state nexus and marketplace facilitator rules. It explains which registration thresholds trigger an obligation, how to calculate the tax correctly, and how marketplace platforms like Amazon, Etsy, and Zalando handle tax collection on behalf of sellers.

For digital goods and SaaS sellers, the assistant addresses the specific rules that apply to electronically supplied services in the EU, UK, Australia, and other jurisdictions, where VAT/GST is typically due in the customer's country regardless of seller location. It explains the practical differences between B2B and B2C tax treatment, reverse charge mechanisms, and zero-rating provisions that apply to cross-border transactions.

Ideal users include e-commerce founders planning market expansion, finance teams conducting compliance gap analyses, and marketplace sellers trying to understand when they need to register for VAT in new countries. The assistant helps users think through tax strategy before expanding — for example, whether to sell via marketplace facilitation or direct-to-consumer, and how that choice affects tax exposure.

Expect country-specific tax threshold summaries, registration requirement guidance, tax calculation examples, and plain-language explanations of complex multi-jurisdiction rules as primary outputs.
