If we add transactions now can you file a return for the previous period?


You want to know if Avalara can file a return for you for a previous month if you add the transactions to your account now.


Avalara Returns


  • Yes, we can file an amended return if one has already been filed or a back-filed return if no return was filed
  • Contact your account manager to discuss a back-filing project
  • Analyze transactions and reports in the Admin Console to confirm all needed transactions are in your account prior to making the request.
    • We are only able to file with the data that is in our service, so Admin Console transactions need to be correct and complete prior to our filing a return for a previous period
