My company has to begin collecting sales tax on orders with ship-to addresses in in New York. Your guidance is appreciate since I couldn't find a thorough user guide/best practices doc in NS help that addresses the full workflow and considerations.

The state collects on behalf of all the counties/cities. The state rate is 4%, and each county/city gets an additional 3-1/8 to 4-7/8. In this case, are the following steps correct?

1. Add one Vendor for the state treasurer
2. Add one Tax Item, select this new vendor as the Tax Agency
3. Import tax table for NY

Or since I'm importing the NY tax table, does this process in itself create a Tax Item for each county/city with appropriate zip codes? Would this rate include the state rate, or do I need a separate Tax Item for the state? Do I need to think about Tax Groups?
