The IRS has established a significant issue ruling program for cerain corporate transactions (Rev. Proc. 2026-21). This program would not diminish the availability of letter rulings under existing programs. This procedure modifies and amplifies the ruling procedures provided in Rev. Proc. 2026-1, I.R.B. 2026-1, 1, and Rev. Proc. 2026-3, I.R.B. 2026-1, 143.

The IRS has announced a new time-limited settlement opportunity for eligible taxpayers involved in conservation easement and historic preservation easement disputes with the IRS. The program aims to resolve cases faster and on terms that are generally more favorable than recent Tax Court decisions. Since 2020, the IRS has settled 405 cases through earlier initiatives, although taxpayers still had to pay penalties and were allowed only limited deductions for certain out-of-pocket costs.
