For my point of view there are too many solution. 1-) Is that customer may have to register himself? If so you may get from his state date from here (when customer register himself you require his state data). This solution can be done in PHP. 2-) If that justomer may not have to register. This is mainly Javascript solution. A liddle js library may solve this. Of course you can post his data to server and calculate tax then post back again. 3-) And or you may generate ajax solution for this. When user selects his state, script auto post and get calculated tax. 4-) and of course BEST WAY is find a professional php programmer. Then tell what do you want. Ps: Also you may guessing STATE via IP number checking.
