Use the tax calculator

This article applies to:Avalara AvaTax Update

The tax calculator calculates tax based on the information you provide us about your business—where you collect tax, the products and services you sell, tax-exempt customers if any—plus any custom rules you set up. Use the tax calculator to preview tax rates, validate addresses, and test tax scenarios.


  1. In AvaTax Update, go to Transactions > Tax Calculator.
  2. Enter the information you want to include in the calculation and click Calculate. To validate an address, click Validate.

AvaTax Update displays the tax calculation at the bottom of the page. The transaction is not recorded. To test advanced tax calculations—such as tax on discounted transactions, transactions with tax included, or transactions with multiple line items—create a test transaction in AvaTax Update.
