If you need to file an amendment to a return, contact your Account Manager by opening a support case. Our Help Center article Amend and file a return late can guide you through preparing your AvaTax invoices for amendment.
Common reasons for amendments include:
- Return invoices are in carryover status
- Nontaxable sales must be credited and rebilled
- Sales to exempt customers must be credited and rebilled
- Additional sales need to be reported
To file an amendment, your invoices in AvaTax must match the expected amounts on your amended returns. Transactions may need to be added to match expectations.
