If you’ve indicated that you are an FBA seller, you could potentially have nexus with all of the states in which there are warehouses. That’s because all those states say that your inventory counts as nexus. We detect the states where you have FBA nexus and add them to your Dashboard with an Amazon badge next to the state name. It’s up to you to decide if you want to collect there or not.
If you want to get rid of those from your dashboard, go to ACCOUNT and click the ‘change’ link next to the state you want to hide and then click on the checkbox next to ‘No longer filing in this state (hide from dashboard)’. The state will be gone from the dashboard.
Here's a more in-depth overview of the features of the Dashboard.
