Sales Tax for Non-Resident LLC Owners: Nexus, Registration & Filing (2026)

A non-resident LLC owner may owe US sales tax — not because of where the owner lives, but because of where the business has “nexus.” If you only sell services, or you sell through Amazon and similar marketplaces, you may owe nothing at all. If you run your own store shipping physical goods into US states, sales tax is very much your problem. Here’s how to tell which camp you’re in.

What “nexus” means (in plain English)

Nexus is just the legal word for “enough connection to a state that it can tax you.” Two kinds matter:

• Physical nexus: inventory in a warehouse, an office, employees, or regular in-state visits. Using Amazon FBA? Your inventory sitting in Amazon warehouses creates physical nexus in those states.
• Economic nexus: selling over a threshold into a state even with no physical presence there. Most states use $100,000 in sales or 200 transactions per year — cross it and you must register.

The marketplace facilitator shortcut

Here’s the relief valve: Amazon, eBay, Etsy, and Walmart Marketplace are “marketplace facilitators” — in nearly every state with sales tax, the marketplace itself collects and remits sales tax on your behalf. If 100% of your sales go through these platforms, you typically don’t need your own sales tax permits. (A few states still want you registered — check the states where your inventory sits.)

When YOU must handle sales tax yourself

• Your own Shopify/WooCommerce store shipping physical goods to states where you have nexus
• Digital products — taxed in some states, exempt in others; there’s no national rule
• Services — most states don’t tax professional services, but a growing minority tax specific ones (SaaS is the classic battleground)

Registration and filing basics

1. Register for a sales tax permit in each nexus state before you start collecting — collecting without a permit is illegal in most states.
2. Configure collection at checkout for the right rates (state + county + city can stack).
3. File on schedule — states assign monthly, quarterly, or annual filing based on your volume. File even for $0 periods; “no sales” still needs a return in most states.
4. Keep exemption certificates for any wholesale/resale purchases.

What happens if you ignore it

States audit remote sellers routinely now. Penalties include back taxes, interest, and fines — and marketplaces can suspend sellers with unresolved tax flags. The fix is cheap compared to the cleanup: registration is usually free or under $50 per state.

Frequently asked questions

I’m a non-resident with no US presence — can I still get a sales tax permit?
Yes. States register foreign-owned entities regularly; you’ll use your EIN and business address.

Do I owe sales tax if I only sell services?
Usually no — most states don’t tax services. But verify for SaaS and digital services, where rules are shifting.

Does Stripe handle sales tax for me?
Stripe offers automated tax calculation (Stripe Tax) as a paid add-on — it calculates, but you still register and file. It’s a calculator, not a compliance department.

What’s the difference between sales tax and income tax nexus?
They’re separate tests with separate thresholds. Having sales tax nexus in a state doesn’t automatically mean you owe that state income tax, and vice versa.
