Single address geocoding and reverse geocoding using latitude and longitude coordinates are supported. The minimum to geocode requires the GeoTAX Premium Masterfile (GPM), which includes data for basic geocoding and jurisdiction assignment. Additional geocoding refinement is available with Master Location Data (KLD) and GeoTAX Auxilliary File (GXF).
Additional data products can be used for tax assignments. Sales tax requires Special Purpose District boundaries (KSP). This can be used with GeoTAX Tax Rate (GTR) to find the Automobile, Construction, General, and Prescription sales tax rates. In addition, a correspondence file can be used to find the unique Vertex code (VLG, VOG, VQG) or Sovos code (TCF). Payroll tax requires Payroll Tax Data boundaries (PXD). Insurance premium taxes require Insurance Premium Tax boundaries (PTD).
