Time to start a subscription business providing up to date sales tax information for every zip code in the country that retailers can integrate into their websites to calculate the correct tax. Who wants to join me :)
Our motto will be “’Cause Interstate Commerce means you have to comply with the Interstate Commerce Clause”
An idea that has been re-invented many times. It's a very expensive proposition that has been shouldered by many companies who had no choice. Sales tax issues go all the way to cities. I chose my favorite Borders bookstore based on city location in the San Diego county area. The ones in the highest city tax areas closed first.
It would need to spit out the sales tax returns too.
Not by zip code. Sales tax is by county and city location.
Unfortunately there could be other zip codes within a ZCTA - the zip code of a ZCTA is just the dominant zip code. I am not sure how many exceptions there are.
Good idea, though.
sales tax information for every zip code in the country

Such a product already exists. And it is more precise than zip code.
Sales tax can vary within a zip code because of various boundaries, and other issues.
