Just a further thought here.....
You said that the tax is by CITY, not by ZIP, and that a city can have more than one zip code. This is, of course, true, but I don't think a single zip code can have more than one city (at least on the post office website, there is only a single city listed as "Default/Acceptable" for each zip code entered.)
However, this still makes Shopsite's tax by zip code feature perfectly appropriate to use.....you just list all the zip codes (actually ranges of zip codes) in different cities to which a particular tax rate applies.
I'm still not sure I see why tax by zip wouldn't work. It may result in a few slight miscalculations (assuming that a zip code can be split into 2 different cities, which again I don't think is possible, per the USPS website.) However, these should be minor and I doubt they'd be a problem given the lack of implementation planning that clearly went into this new law.
I still agree with the basic concept that a complex addition to software shouldn't be made under the onus of a poorly thought-out law that is bound to be revised or repealed.
Also, you mention how the UPS interface calculates a shipping rate baed on address. Actually, I believe the interface again is basing it on zip code only, not a full address (at least the Shopsite version of the API.)
