You may need to run CardValidate Workflow once.

Hi K Khan,

WHere can I find the CardValidate Workflow?

CartHelper.RunWorkflow("CartValidate")

/K

The CartValidate doesn't include tax calculations. Use the CartPrepare workflow if you want to calculate taxes on a cart. The code for that could be:

CartHelper.RunWorkflow("CartPrepare")

or

Cart.RunWorkflow(OrderGroupWorkflowManager.CartPrepareWorkflowName)

The OrderGroupWorkflowManager contains static string variables for each of the three workflows used for carts out of the box.

Here's more documentation on the workflows to better understand them:

The other thing to remember is that Tax calculations can only ever calculate a non-zero tax value for Line Items that

• have a Shipping Address attached to them
• have a valid Tax category associated
• the tax category has rates associated for the jurisdiction of the Shipping Address
• and the rates are non-zero.
