You would like to know what Avalara does in the event your efile credentials become invalid.
It is suggested to reach out to the state to find out their processes on obtaining updated credentials
Once new credentials are obtained, edit your scheduled returns.
Note: With some states, Avalara has filing processes that allow us to file your return without using your efile credentials. It is still suggested to obtain new credentials and update your scheduled returns with the updated credentials so that we have them on file as a backup.
