What is Sales Tax Nexus Anyway?

Your business owes sales tax in any state where it has “sales tax nexus”. In short, if you have sales tax nexus you need to collect and remit sales tax. If you don’t have sales tax nexus, you generally don’t need to get a permit. 

Sales tax nexus is a legal term that means you have crossed a threshold and now have a sales tax collection responsibility in the state. Nexus can be created by having a physical presence, economic presence, or by other factors.  Nexus rules vary by state and retailers have specific nexus rules based on where they have people, property or inventory.  

What Should You Do Once You Determine You Have Sales Tax Nexus?

Once you determine that you have sales tax nexus in Indiana, your next step is to register for a sales tax permit in the state.  Check out our blog post on getting a sales tax permit in Indiana for more information about that process. 

If you are not interested in doing the work of getting the permit yourself, TaxValet can handle the permit registration for you with our Sales Tax Permit Registration Service.
