Parameters

Default output is formatted through ExpressionEngine’s number formatter. Use :numeric when you need an unformatted value for calculations.

Modifiers

To get a raw numeric value for the cart tax total:

{exp:cartthrob:cart_tax:numeric}

Output and Behavior

1. Base value comes from cart->tax().
2. Tax calculation includes:
   • item tax
   • shipping tax
   • minus discount tax
3. The result is never returned below 0.
4. If there are no taxable items, shipping tax can still be returned when applicable.
5. :numeric returns the raw numeric value; default output is formatted text.
