Making the Transaction TAX EXEMPT in CRM

Hello CRM Experts,

We have a requirement to override tax at transaction level in CRM. In ERP this is a standard functionality. Based on Customer/product if the transaction is taxable, at header level by checking the Tax exempt indiactor, the tax is overridden. This is possible in R3. How can we achieve this is CRM?
