Setting Tax Rates According To Zip Code

I have a store which needs to charge tax rates in South Dakota. The sales tax varies according to zip code. is there an add on or is is possible to charge tax rates according to zip code?

Tax rates are based on locations and locations can be setup by zip.

Please take a look

Zipcodes section is not described there, but you can specify zipcodes or zipcode masks for each location
