Was this ever resolved? I've seeing the same issue- the admin shows CA state tax of 7.5% plus LA County tax of 1.5%...however when I checkout with Shopify and Ship to LA County (from LA County) I'm only charged the 7.5% and not the 9%
I have the same issue. My store is not charging ANY sales tax for California residents. The Taxes setup page is confusing so I've just tried unchecking the box for Sales tax is included in my prices. Any help with this would be greatly appreciated!
