Hello there, @ngrantwci.
Thank you for posting here in the Community. Allow me to help share information about paying unemployment taxes.
You'll pay unemployment taxes to the state where the employees are working or to the work location of the employees. If the employees have multi-state work location, you may need to consult the state to verify if you'll need to pay unemployment to that specific state.
If you wish to add another work location, you may check this article: Add another work location.
Keep me posted if you have any other concerns by adding a comment below, I'd be glad to help!
