Where do you owe sales tax registration?
Add every state where you keep inventory, have people, or crossed a sales threshold. For each one you get the free official registration path, and where your company itself must register, we file it for $120 plus the state fee.
We never determine your nexus. You pick the states from your own facts; a tax professional can confirm the list. Sourced reference information, not legal or tax advice.
Which states? Amazon FBA and other marketplace warehouses, employees or contractors, an office, and states where your own direct sales passed the economic-nexus threshold (commonly $100,000 or 200 transactions).
Your plan
ExampleForeign qualification registers your LLC or corporation with that state's Secretary of State. It is separate from a seller permit and only needed when your company itself must be on file there.
How it works
You pick the states
Inventory in a warehouse, an employee, or crossing a state's threshold each create obligations. You know your facts.
Register the free way first
Seller permits are registered directly with each state, free or $10–$100, and one SSTRS registration covers every Streamlined member you pick. We link the official page; no markup.
We file the company-level registrations
Where your company itself must register with a Secretary of State, we prepare and file the foreign qualification: $120 plus the state fee, quoted live at checkout.
What we file, and what we don't. We file foreign qualifications, a live service with the state fee quoted at checkout. We do not file seller-permit registrations, California CDTFA registrations, New York sales tax returns, or Washington Combined Excise returns; states handle those directly and the links in your plan are free. Shopify Tax and similar tools calculate and collect, but no platform can register you with a state.
Frequently asked questions
Amazon collects sales tax on my orders. Am I done?
Not necessarily. Marketplace facilitator laws make Amazon collect on marketplace orders, but more than 20 states treat marketplace inventory as physical presence for the seller, New York still requires a Certificate of Authority and periodic returns, and Washington's B&O tax applies to your gross receipts over $100K even when Amazon collected the sales tax. You collect on your own direct (Shopify/website) sales either way.
Does Shopify Tax register me with states?
No. Shopify Tax calculates and collects for states where you are already registered — it has no way to register you with a state. Registration happens on each state's own site (linked in your plan) or through a service.
What is a foreign qualification and when do I need one?
It registers your existing LLC or corporation with another state's Secretary of State so it can legally operate there. States commonly expect it when you have inventory, employees, or an office in the state. It is separate from a seller permit. We file it for $120 + the state's own fee, quoted live before you pay.
What does SST / SSTRS mean?
24 states have adopted the Streamlined Sales and Use Tax Agreement. Their shared registration system (SSTRS) is free and lets you register for sales tax in any member states you select in one pass. Registering in a member state does create a filing duty there — including $0 returns — so only select states that actually apply to you.
Will you tell me which states I have nexus in?
No — and be careful with anyone who does it from a form. Nexus depends on your inventory locations, revenue by state, people, and each state's current thresholds. This page gives you the sourced facts per state; a CPA or state tax professional can confirm your list.
Is this legal or tax advice?
No. Vermilion Vitez is software for filing, not a law firm or tax firm. Everything here is educational, sourced reference information; confirm requirements with the state or a professional before acting.
