There isn't really an easy way to do that. You could perhaps use the Tax by Zip option and instruct shoppers to enter some specific code in the zip field. Then in the Tax by zip configuration specify that specific code in on of the tax fields and set the % tax for that option. Leave all other tax zones blank so they won't be charged tax if they enter any other zip code.
The problem with doing this is their shipping address would then have that particular code for the zip value and if you did try to ship the product the shipping carrier wouldn't know where to send it.
