TaxJar will automatically tell you where you have FBA nexus by adding the state to your account Dashboard with an Amazon badge next to the state name.
If you see a badge next to the state name, this means that we've seen your inventory being shipped out of a warehouse in that state during the time frame of sales data that we've imported.
- You automatically have nexus in your home state, and since you are an FBA seller, you also have nexus in states where your Amazon inventory is stored.
- Our system detects that your inventory has recently shipped from states where you see that badge.
- At this time, our system does not monitor inventory at rest; this means that the Amazon badge will be added after we see an item ship out to one of your customers from a warehouse in that state.
- If you need to review your FBA inventory, the best way to definitively determine the states where you have nexus would be to regularly check your inventory in Amazon reports.
