I am looking for a subroutine or third party supplier that maintains a routine for calculating sales tax for US customers. I have been refered to Taxware International that prodivides and maintains a product that performs tax calculations based on ZIP codes. I have been told that the calculations are not rocket science —- but maintaining the rules for all zip codes is a major undertaking and it has been sugested that I source this service. Any suggestions??
