Other 2020 TCJA Regulatory Update (All Registrants) The IRS issued proposed regulations for certain provisions of the TCJA in 2018, including rules relating to limitations on interest deductibility. These proposed regulations were issued in November 2018 and should not apply to the Registrants until the year in which the regulations are issued in final form, which is expected to be in 2020. It is uncertain what form the final regulations will take and, therefore, the Registrants cannot predict what impact the final regulations will have on the tax deductibility of interest expense. However, if the proposed regulations were issued as final in their current form, the Registrants could have a limitation on a portion of their interest expense deduction for tax purposes and such limitation could be significant. PPL expressed its views on these proposed regulations in a comment letter addressed to the IRS on February 26, 2019.
