Economic nexus means passing a states’ economic threshold for total revenue or the number of transactions in that state.

These district taxes are often: Regional Transportation District (RTD), Scientific and Cultural Facilities District (CD) or Regional Transportation Authority (RTA) taxes.Retailer’s use tax does not include any local city taxes that may be applicable.
