Sales tax

Register where you sell, before the state notices you should have.

Sales tax is collected in the states where your company has nexus — a physical presence, or sales above that state's threshold. Once you cross it, you need a permit before you collect a cent. We confirm which state that is, prepare and submit the registration, and put the permit number and filing dates in your dashboard.

What it is

The permit that lets your company collect sales tax legally in a state.

A state can require your company to collect its sales tax when the company has a sufficient connection to the state. Physical presence has always counted: inventory in a warehouse, an employee, an office. Since 2018, sales alone count too — most states set the line at $100,000 of sales into the state in a year, some at 200 transactions. Cross either, and you have economic nexus. Forming in Wyoming or Delaware creates no nexus there on its own.

Collect sales tax from customers in that state, legally, and remit it on the schedule the state assigns — monthly, quarterly or annually depending on your volume. It is also what a resale certificate is built on: without a seller's permit, you cannot buy inventory tax-free for resale. Collecting tax without a permit is itself an offence in most states, which is why registration comes first.

Where you register: Where you have nexus; Physical presence — inventory, staff, an office — or sales above the state's economic threshold. Not where the LLC was formed.
Typical threshold: $100,000 in sales; Most states. Texas and California use $500,000. Some states also count transactions.
Marketplace sales: Usually collected for you; Amazon, Etsy and eBay collect and remit in most states as marketplace facilitators. Sales from your own store are not covered.
One registration: One state; Each state issues its own permit. Register in a second state as a second service when you cross its threshold.

Why it matters

Collecting without a permit is worse than not collecting at all.

A founder sells on Amazon, where the marketplace collects sales tax, and assumes that covers everything. Then they open a Shopify store. Shopify does not collect on their behalf, and within a year they have crossed a state's threshold without registering. The state assesses the tax that should have been collected — money the customers were never charged — plus penalties and interest. Registering when the threshold is crossed is a form and a few days; registering after the state finds you is an audit.

1UnregisteredMarketplaces may collect for you, but your own store does not. Cross a threshold, sell for a year, and the state assesses tax you never collected.

How it works

From where you sell to a permit number.

Sales tax is state law, and it differs in every state — thresholds, rates, what is taxable, how often you file. We register you in the state where you have to register and tell you the schedule the state set. We do not prepare returns, and we are not tax advisers. If you sell in many states or sell something with unusual tax treatment, a sales tax specialist is worth the fee.

Thresholds

Most states start counting at $100,000.

Nearly every state now treats Amazon, Etsy, eBay and Walmart as marketplace facilitators, meaning the marketplace collects and remits on your sales there. Those sales still count toward your threshold in many states, and sales through your own website are entirely yours to handle. Most founders who need a permit need it because of the store they run themselves.

Typical threshold: $100,000 in sales into the state in a year
Texas, California: $500,000
Marketplace sales: Usually collected by the marketplace, but still count toward your threshold in many states
Wyoming, Delaware: Forming there does not create sales tax nexus there

Not because you formed there. Nexus comes from physical presence or sales into the state. A Wyoming LLC with no inventory, staff or customers in Wyoming has no Wyoming sales tax obligation.

Usually not for those sales — Amazon collects and remits as a marketplace facilitator in almost every state. If you also sell from your own store, or have inventory in a state's warehouses, the answer can change. We check before registering you anywhere.

We prepare and submit the application within one business day of having your details. Some states issue a permit number online within days; others post it, which can take a few weeks.

Collect the state's sales tax on taxable sales to customers in that state, and file returns on the schedule the state assigned — usually quarterly to start. The filing dates go into your dashboard. Filing itself is ongoing work for you or your bookkeeper.

No. A sales tax permit lets you collect tax from customers. A resale certificate lets you buy inventory without paying tax to your supplier. The certificate requires the permit. Sellers who buy wholesale usually need both.

Most states charge nothing to issue a permit. A few charge a small fee or require a security deposit for new registrants. Where a state charges, it is invoiced at cost.
