EXTREME Sales Tax Nexus Analysis — Know Exactly Where You Must Register
Selling into US states but not sure where you owe sales tax? We map your physical and economic nexus state by state, against current thresholds, and hand you a clear registration recommendation list — so you stop guessing.
What Is a Sales Tax Nexus Analysis?
“Nexus” is the legal term for a connection strong enough that a state can require you to register, collect and remit sales tax. There are two kinds: physical nexus — an office, warehouse, employees or inventory in a state — and economic nexus — selling into a state above its sales-volume or revenue threshold (thresholds vary by state).
Since South Dakota v. Wayfair (2018), states can require remote sellers to collect based on economic activity alone — no physical presence needed. This page sells analysis only: we map where you likely have nexus and recommend where registration may be required. The registration decision stays yours, and outcomes are not guaranteed — states interpret their own rules differently. But with the map in hand, you stop guessing and start deciding from facts.
Who Needs a Nexus Analysis?
If you sell across state lines — or even suspect you might — this analysis answers the one question every seller asks:
- E-commerce sellers shipping to multiple US states — Shopify, WooCommerce, Etsy and own-website sellers.
- Amazon FBA sellers — inventory in a fulfillment center is physical nexus in that state. If you do not know where your stock sits, that is the first thing we map.
- Digital and product sellers with growing out-of-state revenue — economic nexus can trigger silently as you grow.
- Companies unsure whether they need to register anywhere yet — a clear yes/no/soon list beats months of uncertainty.
- Businesses expanding into new states — check nexus before you sell, not after the state finds you.
- Sellers told “you might have nexus” — and wanting a documented answer instead of a vague warning.
What’s Included in Our Nexus Analysis
A documented, state-by-state answer — not a phone call and a shrug:
Sales Footprint Review
We review your sales by state — where you sell, how much you sell there, and through which channels and marketplaces.
Physical + Economic Nexus Assessment
Your footprint is assessed against current state thresholds for both kinds of nexus — warehouses and employees, plus sales volume and revenue.
State-by-State Recommendation List
A clear list of where registration may be required, where you are borderline and should watch, and where you are fine for now.
Registration Handoff
For the states you choose, we hand you straight to our Sales Tax Registration service to get the permits done. Clean records help everything — see our Bookkeeping service.

Nexus Analysis vs. Sales Tax Registration
Two different services, in the right order. Mixing them up is how sellers pay for permits they never needed:
- Nexus analysis tells you WHERE you may need to register. That is this page — the map, the thresholds, the recommendation list.
- Sales tax registration actually registers you in those states — permits, tax accounts and filings set up properly. See our Sales Tax Registration service when you are ready.
- Already registered somewhere and the permit went inactive? You do not need a new analysis for that state — see Sales Tax Permit Reactivation to bring it back.
Analysis first, registration second. In that order you register exactly where you must — and never pay for a permit in a state that cannot touch you. Expanding the business itself into new states? Our Foreign Qualification service covers the company side of that move.
Sales Tax Nexus Analysis — Frequently Asked Questions
What is sales tax nexus, in plain words?
A connection to a state strong enough that the state can require you to register, collect and remit its sales tax. It comes in two kinds: physical nexus (an office, warehouse, employees or inventory in a state) and economic nexus (selling into a state above its sales-volume or revenue threshold).
What did the Wayfair case change?
In South Dakota v. Wayfair (2018), the US Supreme Court allowed states to require tax collection from remote sellers based on economic activity alone — so a state can now reach you even with no physical presence there.
Do nexus thresholds differ by state?
Yes. Every state sets its own rules and thresholds, and they change over time. We use current figures in your analysis — we do not quote fixed numbers here because fixed numbers go stale.
Does my Amazon FBA inventory create nexus?
Yes. Stock sitting in a fulfillment center is physical nexus in that state — one of the most common nexus triggers we see for Amazon sellers. Tell us where your inventory sits and we map every one of those states.
Do I need to register for sales tax in all 50 states?
Almost never. Most sellers need only a handful of states. The analysis exists precisely to tell you which states those are — so you register where you must and skip the permits you do not need.
How much does a nexus analysis cost?
It depends on how many states and sales channels are in your footprint. Message us on WhatsApp with your sales picture and we will share the exact price.
