If you marked an item as non-taxable in Square but the tax is still being applied at checkout, this is caused by a Square tax setting, not Birrdi or the item itself.
Square has a global tax rule that can override your item-level taxable toggle.
Why This Happens
Every Sales Tax in Square has a setting called “Apply tax to”.
There are two modes:
1. “All current and future taxable items at selected locations”
(This is Square’s default and it often causes confusion.)
When this is selected:
Square automatically applies this tax to all items, regardless of whether you toggle an item as taxable or non-taxable.
Your item-level setting is overridden.
This is why operators still see tax even after marking an item as non-taxable.
How to Fix It
To allow Square to respect your item-level taxable settings, you must switch the tax rule to Select items.
Steps
Open your Square Dashboard
Go to Settings → Payments --> Sales Taxes
Click on your Sales Tax
Scroll to the section labeled Tax application
Change the dropdown from:
“All current and future taxable items at selected locations”
TO
“Select items”Once “Select items” is selected, Square will allow you to choose exactly which items the tax applies to.
Summary
If you toggle an item as non-taxable, but Square still charges tax:
It’s because your Sales Tax is globally set to apply to all items.
Update the Sales Tax rule to Select items.
Square will then only apply tax to the items you choose, and non-taxable items will be correctly left tax-free.
