## Summary

**Requires federal validation of Electronic Filing Identification Numbers (EFINs) before they can be used to file tax returns.** This bill would create a Treasury-run program that checks EFINs in real time, blocks unvalidated or compromised numbers, and requires filing software to enforce those checks. - Tax preparers and authorized users: The bill would prohibit using an EFIN to electronically file any return or document unless that EFIN is validated and the user is authorized for the specific filing activity. Validation must occur before initial use and at intervals or on events needed to maintain EFIN integrity. - Tax software providers: Software that enables electronic filing must enforce validation and support high-volume automated checks. The validation system must immediately confirm validity and flag suspensions, revocations, compromises, or ineligibility. - Treasury and oversight: The Secretary must establish the validation program within 24 months and submit a 180-day implementation plan to the tax committees. Within two years after the program is set up the Secretary must report on performance, disruptions, validation counts, contingency use, and any recommended changes.
