We want to implement standard (out of the box) functionalities of tax for US Sales Tax. Requirement is to 1) configure sales tax for about 20 states for State tax, County tax and City tax and all possible combinations of these taxes 2) Use standard and/or customized reports (tax returns, tax exemptions etc.) based on these tax configurations.
Can you please guide me on this? Is there US Tax Localizations available (just like Microsoft offers India Tax Customizations)? We don't want to use a third party solution or ISV solution.
Any case study, documentation relevant to this will be helpful and appreciated.
