How it works

How we handle Sales Tax Compliance, end-to-end.

Multi-state sales tax compliance is the biggest operational tax burden for online businesses.

1

Nexus assessment

We assess: economic nexus (typically $100K sales or 200 transactions per state), physical nexus (offices, warehouses, employees), inventory nexus (FBA, 3PL, drop-ship). Identify all states where you have nexus.

2

Multi-state registration

Register for sales tax in each nexus state. Coordinated across states. State registration fees pass through (typically free; some states $20-$50).

3

Monthly returns

File sales tax returns in each registered state on the state's schedule (usually monthly for medium volume; quarterly for small; annual for tiny). Tax remitted via state portal.

4

Exemption certificate management

Tax-exempt customers (resellers, nonprofits, government) provide exemption certificates. We collect, validate, and store for audit defense.

FAQ

About the Sales Tax Compliance Subscription.

Do I need to register in every state?
No. Only states where you have nexus: economic nexus (typically $100K sales or 200 transactions), physical nexus (offices, warehouses, employees, inventory). Most online businesses have nexus in 10-25 states. Few have nexus in all 46.
What is economic nexus?
Nexus established by economic activity alone (without physical presence). South Dakota v. Wayfair (2018) allowed states to require sales tax registration based on $100K sales or 200 transactions thresholds. Almost every state has economic nexus laws now.
What about marketplace facilitator?
For sales through marketplaces (Amazon, Etsy, eBay), the marketplace collects sales tax in most states. You may not need to register for those sales. Your direct website sales remain your responsibility for nexus.
What is sourcing?
How tax rate is determined for a sale. Destination sourcing: tax based on customer's location (most states). Origin sourcing: tax based on seller's location (a few). Different rules require different calculations.
What are exemption certificates?
Documentation from tax-exempt customers proving their exemption (resellers buying for resale, nonprofits, government). You collect at customer onboarding. Without certificates, you charge tax. Lost certificates = state can audit and you owe the tax.
What is the audit risk?
States audit sales tax aggressively. Common targets: failing to file in nexus states (statute of limitations does not start until filing), missing exemption certificates, undercharging tax on taxable items. Multi-state sellers face higher audit volume.
