Tax Compliance Automation

Overview

Tax compliance for ecommerce is one of the most complex operational challenges at scale. In the United States alone, there are over 13,000 taxing jurisdictions with different rates, product taxability rules, filing frequencies, and economic nexus thresholds. Internationally, VAT (Europe, UK, Australia) and GST (Canada, India, New Zealand) add additional compliance layers with their own registration thresholds, invoice requirements, and reporting obligations.

This skill covers the full tax compliance lifecycle: nexus threshold tracking to know when you must register in a new jurisdiction, real-time tax calculation at checkout, exemption certificate management for B2B customers, automated filing, and audit-ready reporting. All major platforms have direct integrations with TaxJar and Avalara that handle this without custom code.

When to Use This Skill

• When your store ships to customers in multiple US states and you are unsure of nexus obligations
• When you need to collect EU VAT under OSS/IOSS for European customers
• When building B2B ecommerce that requires exemption certificate management
• When current tax rates are hardcoded and have not been updated in 12+ months
• When preparing for an audit and you need documented, reconcilable tax records
• When launching in a new country and you need to understand VAT/GST registration requirements
