Do I need to collect sales tax?
If you have 'nexus' (a significant presence or sales volume) in a state, yes. We help you figure out exactly where you owe.
What is sales tax nexus?
Nexus is a connection or presence in a state — whether through employees, inventory, or affiliate relationships — that requires you to collect and remit sales tax there. We help identify all your nexus exposures.
I sell on Amazon and my own site. Do I still owe sales tax?
Yes. Marketplace facilitators like Amazon handle some states, but not all. If you sell directly to customers in states where you have nexus, you may owe use tax that marketplaces don't cover.
Can I backfile missed sales tax returns?
Yes, and it's often the right move. We help businesses catch up on missed filings, reduce penalties through voluntary disclosure, and get compliant going forward.
