We use IMPLAN Pro so the fiscal impact results are shown in aggregate (state and local combined). We understand how to split state and local when the model geography is an entire state. We simply use the ratio of collected taxes in the state and local jurisdictions reported in the Annual Survey of State and Local Government Finances.
However, the ratio of local to state taxes is different if the direct geography is just one county. For example, if all the direct activity occurs in Philadelphia, the ratio of local to state will be higher than if the event occurs throughout Pennsylvania. How, in that case, can we find income, sales, and business taxes for both Philadelphia and Pennsylvania using the fiscal impact output provided by IMPLAN?
