Nexus

What is nexus?

“Sales tax nexus” is the connection between a seller and a state that requires the seller to collect and remit tax on sales made in that state. If you have nexus in California and Texas, for example, you must collect and remit sales tax in California and Texas.

Each state where you do business has its own nexus laws. So determining where your business has nexus can be complicated and time consuming. Many states have also expanded their definitions of nexus in recent years, so it’s important to stay up to date with recent legislation.
