You just added nexus for a new state, but tax is calculating on transactions that are before the date you added the new region to your nexus.
- When you use the default date when adding nexus, it is predated one year in the past, check the year:
- Go to Organization > Nexus > Review the date by the jurisdiction in question
- Correct the year (and month, day if needed) then click Save
Note: Calculating tax occurs as of the start date selected in Nexus, Nexus changes take effect immediately upon Save.
