It is a secure process developed by the Department of Revenue (DOR) for sales tax registrants and/or their representatives to transmit sales/use tax return data to DOR via an electronic file over the Internet.
Carefully review the information and instructions at Sales and Use Tax e-File Transmission.
Payments must be made by Electronic Funds Transfer (EFT).
Electronic returns cannot be recalled or intercepted after transmission. Changes to any entries after a return has been acknowledged must be retransmitted as an amended return. Use "Replace" for the "purpose" of sales and use tax filing attribute, which will replace all previous information from the original return or from any previous amended return.
