It doesn't for me. My city is in two counties. They have different sales tax. One address I know is the in "other" county and has a reduced sales tax. I added a shipping address of the service location where I photograph and have to use that city/county's sales tax chart. It did not charge appropriately and the Realtors' will not usually know the 4-digit code for the house they list. Only the standard one (which is the same throughout the city).
