Tax rate- options for varying tax codes per proposal/ customer

I haven't researched this yet but for where I live in Washington we have to assign a different tax rate depending on the zip code. So i service about 30 zip codes and most of my proposals will have different tax amounts I'll be charging depending where the project is located. When I used Joist they had a section to fill in these tax rates and name them. Than apply which ever one matched to that jobs proposal. I don't know how taxes work in other states but I feel I can't be the only one who would need this.
