US Sales Tax Nexus: Automated Compliance Post-Wayfair

The Complex Web of American Sales Tax

Unlike countries with a flat national VAT, the United States has over 10,000 local sales tax jurisdictions. Following the landmark Wayfair Supreme Court decision, businesses selling across state lines must track their "economic nexus" in each state individually.

Understanding Economic Nexus

• Transaction & Revenue Thresholds: Most states enforce tax collections once a seller exceeds $100,000 in sales or 200 separate transactions in that state.
• Exemption Certificates: Tracking and verifying wholesale tax exemption certificates securely.
• Reporting: Filing different tax reports for municipal, county, and state tax bodies.
