​The department will generate an acknowledgement of acceptance or rejection for all returns received. The acknowledgement schema is in the schema package at ...StateExcise/Acknowledgment.xsd (WIExcise2012V2.0.zip). Transmitters and software developers should allow one business day to receive the state acknowledgement before contacting the department. Most acknowledgements will be available within an hour.
