Sales tax and multi-state compliance
Selling online or working across state lines creates obligations most owners don't see until a letter arrives. We map where you have nexus, register you where required and keep the filings on schedule.
Best for: e-commerce sellers and consultants with clients in several states.
How it works
Map
We review economic and physical nexus across all states, including inventory in fulfillment warehouses.
Register
We register you where you're required to collect and set up a filing calendar.
Reconcile
Marketplace sales on Amazon, Etsy and Shopify are reconciled so tax collected by the marketplace isn't counted twice.
Clean up
If you have past exposure, we pursue voluntary disclosure agreements to limit it.
Why it matters
Sales tax you should have collected but didn't usually comes out of your own pocket. Exposure builds quietly, one state at a time, as sales grow or inventory moves into new warehouses.
A nexus map and a filing calendar turn a growing risk into a routine task.
Which plans include it
Sales tax and nexus management are included in Executive. Multi-state income tax apportionment and pass-through entity tax elections are part of this service too.

- What is nexus?
- It's the connection with a state that obligates you to collect and remit its sales tax. Since the 2018 Wayfair decision, most states use sales thresholds — commonly $100,000 a year — not just physical presence.
- Doesn't Amazon handle sales tax for me?
- Marketplaces collect tax on sales made through them in most states, but not on sales through your own website.
- What if I should have been collecting already?
- A voluntary disclosure agreement can often limit how far back a state looks and reduce penalties. We'll assess whether it makes sense.
