This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status.

The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

The subject of the public hearing is the notice of proposed rulemaking (REG-121244-23) published in the Federal Register on Wednesday, February 4, 2026 (91 FR 5160). To accommodate all persons who wished to present oral comments at the public hearing, by notice of hearing published in the Federal Register on Wednesday, April 29, 2026 (91 FR 23038), the public hearing scheduled Thursday, May 28, 2026, was extended two additional days to begin Wednesday, May 27, and end Friday, May 29, starting at 09:00 a.m. ET each day. All three days of the hearing will now be held in a telephonic-only format.
The rules of 26 CFR 601.601(a)(3) apply to the public hearing. Persons who wished to present oral comments at the public hearing were required to submit an outline of the topics to be discussed as well as the time to be devoted to each topic by April 6, 2026. This due date for requests to testify has now passed. Persons who made timely requests to testify either in-person or by telephone will receive the telephone number and access codes for the public hearing. A period of 10 minutes will be allotted to each person testifying.
Individuals who have already sent an email to publichearings@irs.gov to request to attend the hearing by telephone or in person do not need to make a second request to attend the hearing now being held by telephone only. The IRS will provide those individuals with a telephone number and access code for the rescheduled hearing by email.
An agenda showing the scheduling of the speakers will be prepared after the deadline for receiving outlines has passed. Copies of the agenda will be available via the Federal eRulemaking Portal ( www.regulations.gov) under the title of Supporting & Related Material.
Individuals who want to attend the public hearing by telephone without testifying must also send an email to publichearings@irs.gov to receive the telephone number and access code for the hearing. The subject line of the email must contain the regulation number (REG-121244-23) and the language “ATTEND Hearing Telephonically.” For example, the ( printed page 25159) subject line may say: Request to ATTEND Hearing Telephonically for REG-121244-23. Requests to attend the hearing must be received by 5:00 p.m. ET on May 22, 2026.
Public hearings will be made accessible to people with disabilities.
