State-specific rules
Each state may apply different rules for nexus, taxability, registration, exemptions, and filing frequency. Marketplace facilitator rules may also affect who collects and remits tax on certain marketplace transactions.
Simplify multistate sales tax compliance, organize exemption records, and identify areas for review.
Sales and use tax compliance can become complicated when your business sells across state lines, expands into new markets, or manages transactions with different tax rules.

Selling in multiple states can create additional compliance requirements. Each state may apply different rules for nexus, taxability, registration, exemptions, and filing frequency.
Economic nexus laws may require a business to collect and remit sales tax based on economic activity in a state, even without a physical location there. Following South Dakota v. Wayfair, states may impose collection obligations on remote sellers that meet state-specific economic thresholds. Economic nexus rules vary by state. For example, South Dakota's framework used $100,000 in sales or 200 separate transactions, but other states apply different thresholds and measurement periods.
Use tax may apply when a business purchases taxable goods or services without paying the required sales tax. Unreviewed vendor invoices, equipment purchases, supplies, and other business expenses can create potential use tax exposure. We help businesses improve visibility into purchases that may require use tax consideration.
Accurate sales tax reporting depends on complete transaction data and consistent reconciliation procedures. The exact scope of preparation, electronic filing, and payment services depends on the agreed engagement.
