📔 Objective

After creating a free organization, and configuring a payment method, if we are to try to upgrade the organization to either Families, Teams or Enterprise, we're getting a 500 error back.

This pull request fixes an unrelated error where taxInformation could be undefined in the component, and throw an error.
