How sales tax affects the shopping cart

The customer selects a State in the Delivery address section of the cart. The order summary shows a state-specific tax line, including the state name, configured percentage, and tax amount. In the supplied example, the delivery state is New Jersey, so the cart shows New Jersey Sales Tax (6.625%). Image

Shopping cart example

In this example, the displayed amounts reconcile as follows:
  1. Tax calculation base: $1,007.60 - $50.46 + $30.00 + $73.94 = $1,061.08.
  2. Sales tax: $1,061.08 × 6.625% = $70.30 after rounding.
  3. Final total: $1,061.08 + $70.30 = $1,131.38.

​
Verify your configuration

After adding or changing a state rate, test a cart with a delivery address in that state. Confirm that the tax line displays the expected state, percentage, and amount, and that the final total reflects the tax. Repeat for each state you configure.
