Calculating Tax on Billing Documents Using Avalara AvaTax

If your org is configured to use Avalara AvaTax to calculate tax on billing documents, you can calculate tax for a single billing document from its detail page or for multiple billing documents from the list view. Read Using Avalara AvaTax for Tax Calculation before calculating tax.

You can only calculate tax for billing documents with the status "Draft" or "Ready for Review" where the External Tax Status is not "Finalized".

After calculating a billing document's tax using Avalara AvaTax, if you make changes to the document that might impact its tax value, the document's External Tax Status changes from "Calculated" to "Not Calculated". The document's Tax Calculated checkbox is also cleared, indicating that tax needs calculating again. Some changes can indirectly impact a billing document's tax value but do not cause the External Tax Status to change to "Not Calculated" or clear the Tax Calculated checkbox, such as editing the Tax Exemption Status field on the Account.

Warning:

Calculating tax on a billing document might cause the document to be completed without warning. This happens if the Billing Central Automation feature is set up to automatically complete billing documents when their tax is calculated. Once a billing document's status is "Complete" you cannot commit its tax to Avalara AvaTax. Therefore if you want to commit tax manually, make sure the Billing Central Automation feature is not set up to automatically complete billing documents.
