Resolve the Incorrect Calculation of Tax on the Shopping Cart

When a user adds an item to cart and views the Shopping Cart page, the Cart automatically calculates Sales Tax based on Setup > Accounting > Setup Taxes, Home Tax Code instead of Default Tax Code.

Here are the steps to workaround this issue:

1. Verify if Advanced Taxes is enabled. Navigate to Setup > Company > Enable Features, Accounting tab, Advanced Taxes box.

2. When Advanced Taxes is disabled: 
       a. Navigate to Setup > Accounting > Set Up Taxes > click Add New State button 
       b. On New State pop-up record set State/Province/Country = Any State other than the State of the company

       c. State/Province/Country = Any State other than the State of the company 
       d. Save
