State rates are a good start...but check out NY rates, which have multiple rates per city. Or TN - they have rates which vary by county and purchase amount. Sales tax is a bit of a rabbit hole issue no matter how you slice it. Unless you live in NH ;-)

CA has a base tax rate that is then increased based on the county/city/district rate.
Even within a County we can have more than one final rate.

I have to agree that the fucntion falls short! Does anyone have a good idea on how best to account for the tax codes of states like OH, CA, and NY?

This should not be a function, but rather a table and have a lookup copy the tax data over.
