Frequently Asked Questions

What is nexus?

Nexus is the connection that gives a state the right to tax your business. It can come from property, employees or remote workers, and for sales tax, from sales into the state even without a physical presence.

We sell online. Do we owe sales tax in other states?

Possibly. Most states require out-of-state sellers to collect sales tax once sales into the state pass a dollar or transaction threshold. We review where you sell and tell you where you need to register.

What changed with Pennsylvania local sales tax in 2026?

Act 21 of 2026 moved Pennsylvania local sales tax to destination sourcing, and the Department of Revenue began enforcing the new rules on October 1, 2026. Read what Act 21 means for your business.
