On May 14, TIGTA released a report, Status of the Office of Chief Counsel’s Issuance of TCJA Guidance. It reviewed the process for issuing guidance on the 100+ provisions of the Tax Cuts and Jobs Act (P.L. 115-97; 12/22/17). It also lists the guidance issued through the end of March (83 items) and what is expected from that date (95 items). A good amount of this includes Treasury Decisions, meaning final regs of the numerous proposed regs issued so far. Here is the detail of what they still plan to issue:
44 Treasury Decisions
4 Revenue Rulings
6 Revenue Procedures
Appendices to the report list the specific topics of the guidance.
