Steps
Obtain IRS e-file authorization as a transmitter/software developer, or use IRS-approved commercial software for employment tax e-filing
Download the current tax-year 94x XML schemas and business rules from the IRS employment-tax MeF schemas page
Construct the Form 941 XML return, including any required attachments (Schedule B, Schedule D, Schedule R, or Form 8453-EMP as applicable) conforming to the published schema
Transmit the XML package to the employment-tax MeF system and capture the submission ID
Poll for and retrieve the acceptance/rejection acknowledgment, correcting and retransmitting for any schema or business-rule validation errors
Known gotchas
Employment tax MeF accepts only the current-quarter return plus returns for the two prior years — older delinquent returns must be filed on paper
94x schemas and business rules are republished each tax year, and the IRS has issued urgent mid-year schema updates in the past, so hardcoding a schema version will eventually break
Employment-tax MeF is a distinct program from income-tax MeF (used for 1040/1120/1065/etc.) — credentials, schemas, and transmission endpoints are not interchangeable between the two
