What it is

Sales Tax Registration, plainly.

Sales tax is collected by sellers, then remitted to the state. Whether you have to collect depends on nexus: economic nexus (you crossed the state\u2019s revenue or transaction threshold), physical nexus (you have inventory, an office, or employees in the state), or marketplace nexus (you sell on Amazon, Etsy, Walmart, who collect for you in some states).

After the Supreme Court\u2019s 2018 Wayfair decision, every state with sales tax can require out-of-state sellers to collect once they cross a threshold (most commonly $100,000 in sales or 200 transactions per state per year). This means an e-commerce seller can hit nexus in 10+ states without ever stepping foot in any of them.

We assess where you have nexus, file the sales tax permit application in each state, set up sales tax tracking in your books, and connect to filing software (Avalara, TaxJar) for ongoing returns. Each state is its own filing with its own form and fee.

Who this is for

Common situations.

FAQ

Common questions.

What is nexus?
The connection between your business and a state strong enough to require sales tax collection. Three main types: economic (revenue/transaction threshold), physical (inventory, office, employees), marketplace (sold via Amazon, Etsy, etc.).
What changed in 2018?
South Dakota v. Wayfair allowed states to require out-of-state sellers to collect sales tax based on economic activity alone. Most states adopted $100,000 or 200-transaction thresholds.
Does this apply to SaaS?
In 19+ states, SaaS is taxable. The list grows. Software-as-a-service falls under sales tax in states like New York, Pennsylvania, Texas, and Washington.
What about Amazon FBA inventory?
FBA inventory in a warehouse creates physical nexus in that state. This is true in most states, regardless of your revenue level.
Marketplace facilitator laws?
Most states now require marketplaces (Amazon, Etsy, eBay) to collect sales tax on behalf of sellers. You may not need to register in marketplace-facilitator states if you only sell there via the marketplace.
What if I have not been collecting?
We can help with voluntary disclosure agreements (VDAs) that let you become compliant going forward with reduced penalties on past sales.
How fast is permit issuance?
Varies: same day in many states (Texas, Florida), 2 to 6 weeks in slower states (California, New York).
Is there a state fee?
Most states do not charge for the permit itself. A few (Indiana, others) charge $25 to $50.
Do I need this for every state I ship to?
No. Only states where you have nexus. We assess this.
How do I file ongoing returns?
Through Avalara, TaxJar, or another filing tool. We set this up during registration.
