You can use the tax calculator to check if a customer's exemption would be applied in a transaction.

1. Run a control transaction.
   1. Log in to New Global Tax Determination Cloud and click Tax Calculator in the menu.
   2. Leave the default values in the Document-level settings section.
   3. In the Locations section, select Ship To for Location 1, then enter the address.
   4. Click Add another location, then select Ship From for Location 2 and enter the address.
      Read more on what kind of location information you should provide.
   5. In Line item settings, select the payment type and transaction type or leave the default settings: debit and sale.
   6. In the Line Items section, enter the gross amount and leave the other fields blank.
   7. Click Calculate Tax.
      The tax amount will be displayed in the Results slide-out panel.
   8. Make a note of the tax amount, then close the slide-out panel by clicking the Close icon.
2. Apply the exemption.
   1. Leave all the values in the fields and scroll down to the Line Items section.
   2. Click the magnifying glass icon in the Entity/Use Code field.
   3. In the slide-out panel, select the Entity/Use Code mapping you need, then click Apply.
      In this example, we are using RESA - Resale Certificate. The Entity/Use Code field on the main screen will be populated with the Resale MyEntity/Use Code that was previously mapped to the RESA - Resale Certificate Entity/Use Code.
   4. Click the Add icon next to the Entity/Use Code field, then select a customer or vendor from the options.
   5. In the Customer / Vendor section, select the Customer button, then begin typing the customer's name until the full customer name appears in the dropdown menu.
   6. Click the customer's name, then click Calculate Tax.
      In the Results panel, you can see that in this example the exemption was applied and the customer was not charged any tax. This means that if a real transaction with these exact details is passed into Global Tax Determination from the customer's ERP, they would not be charged any tax.
