We don't have any way to determine the proper sales tax for a buyer outside of their zip code, so it is necessary to associate different rates with different zip codes.
It is not necessary to list every individual zip code though, you can use zip code prefixes to set special rates for entire ranges of zip codes and then only enter the specific zip codes in that range that are an exception.
For example, if you need to charge 6% for all zip codes from 12300 to 12399, but 7% for the 12340 to 12349 range you would enter the following two entries into our advanced tax settings:
You could also set a base rate for an entire state by entering a line that reads:
NY[or applicable state abbreviation],6.25
Our system will select the most specific line to apply to any given buyer. So the statewide rate will only apply if there is no entry specific to the buyer's zip code. And any buyer in the 12340 to 12349 range will get 7% instead of 6% because they fall under a more specific entry.
