Here is my solution, As Zettle applies tax rates on each item when created in the inventory, each item must be edited. On a computer log into your account, create your tax rate. Then go to inventory click export. This will export your entire inventory. Now in excel (or other software) find the column with the desired tax rate. Select the entire column and use find/replace to change "No" to "Yes" . If multiple tax rates are present, make all others say "No" Save file. Now import that inventory to your account. Open app on mobile device, test by adding items to your cart. Desired tax rate (the one you changed to "yes") should be applied automatically as items are added to cart. This will need to be done anytime you change tax rates. Make sure to save a copy of your inventory as a separate file from the one you are editing. Just to be safe. Hope this helps
