Keep Modernized e-File. Improve the retained document around it.

IRS Modernized e-File uses XML schemas, business rules, submissions/transmissions and acknowledgement files. Authorized providers operate preparation and transmission workflows. Those systems remain authoritative for processing and acceptance.

Proposed complementary path

1. Approved tax software produces the required MeF XML and supporting files.
2. A UDR represents the human-readable retained filing and references its structured payload/support package.
3. The existing MeF provider transmits; the IRS acknowledgement remains the evidence of accepted or rejected processing.
4. A UDS preserves the exact retained state and can reference—but must not impersonate—the acknowledgement.
5. An amendment derives a new UDR and preserves the prior final state.

UD does not transmit through MeF, pass IRS business rules, prove acceptance or establish tax correctness.
