No retainer · ACMA CGMA reviewed · One-time per state registration

Post-Wayfair (2018), every US state can require out-of-state sellers to collect sales tax once they cross economic nexus thresholds (typically $100K revenue OR 200 transactions/year in the state). E-commerce founders hit thresholds and panic. Marketplace facilitator laws shift some burden to Amazon/Etsy/Shopify, but direct sales + B2B + many service sales still create registration obligations. TaxCloud charges $249/state, Avalara wants a $403/location subscription. We do nexus review + state registration + filing-frequency setup at $199/state, or $499 for 3-state nexus packs.

FAQs

How do I know if I have nexus in a state?

Two types: (1) Physical nexus — inventory in FBA warehouses, employees, offices, contractors. (2) Economic nexus — $100K revenue OR 200 transactions/year (varies by state — some are $250K, some $500K). Our nexus review documents both for your situation.

I sell on Amazon FBA — do I need to register everywhere FBA has warehouses?

Historically yes; recent state changes (marketplace facilitator laws) shifted collection responsibility to Amazon for marketplace sales, BUT you may still have a registration filing obligation in some states and you certainly do for direct sales (Shopify, your own site) that ship from those FBA inventory states. We assess state-by-state.

What about SaaS — is software subject to sales tax?

Varies enormously by state. ~20 states tax SaaS (Texas, New York, Massachusetts, Washington, Pennsylvania, etc.). ~30 do not (California, Florida, Illinois). Some states tax cloud computing but exempt SaaS narrowly defined. Our review identifies your taxable footprint.

Do you handle monthly sales tax filing after registration?

No — that's automation territory. We route to TaxJar (best for sub-100K transactions/yr) or Avalara (enterprise). We can set up either as part of the registration if desired (+$199 setup).

What about marketplace facilitator states?

Where applicable (now 45+ states), the marketplace platform (Amazon, Etsy, eBay, Walmart) collects + remits sales tax on your behalf for marketplace sales. You may still need to register for sales NOT on the marketplace (your own site, B2B direct), and for some states you still file a "marketplace facilitator" return showing the $0 net obligation. We handle this distinction in setup.
