Modernized e-File (MeF) for employment taxes Definition A transmitter sends the electronic return data directly to the IRS. Electronic Return Originators (EROs) may apply to be transmitters and transmit return data themselves, or they may contract with an accepted third-party transmitter to transmit the data. A transmitter does not have signature authority for the taxpayers that it services. Getting started To participate in Modernized e-File (MeF) for employment taxes, prospective participants must first complete and submit an IRS e-file application. You must complete the IRS e-file application online after registering for e-services. Additional guidance can be found in Publication 3112 PDF. Follow the instructions provided to complete your application. If you have questions, or require assistance completing the IRS e-file application, phone 866-255-0654 (toll-free).

Acknowledgements An Acknowledgment (ACK) File will be returned for each successfully transmitted return or PIN registration file. Transmissions are processed as received, so ACKs will be available as soon as the transmission has been processed. The ACK will provide the status of the transmission informing the submitter of its acceptance or rejection. If a return is rejected, the ACK will identify the source of the rejection and provide business rule text that explains why a transmission or return rejected.
