Following the initial public release of private letter ruling (PLR) 20242002 as part of a state rate proceeding, on June 28, 2024, the IRS publicly released that ruling, as well as two companion rulings obtained by other affiliates subject to the jurisdiction of different state public utility commissions, PLRs 20242003 and 20242004 (all dated March 8, 2024). (See Holland & Knight's previous alert, "IRS Rules Utility's NOL Carryforward Cannot Be Reduced by Tax Allocation Payments," May 8, 2024.)

In general, the PLRs ruled that the normalization mechanical deferred tax computational rules of Treasury Regulation Section 1.167(l)-1(h) and the consistency rules of Section 168(i)(9) precluded the reduction of a regulated utility's net operating loss (NOL) by intercompany tax allocation payments received from profitable members of the consolidated group that were able to use the NOLs.

The rulings provided that because the mechanical deferred tax reserve computational rules are based exclusively on the difference between book and tax depreciation multiplied by the statutory tax rate, the introduction of another variable into the calculation (i.e., the profits of the affiliates who used the net operating loss carryforward (NOLC) to offset tax liability) would violate those rules. Further, the consistency rules under Section 168 required that any projections or adjustments to any one of the four normalization consistency elements (tax expense, depreciation expense, the reserve for deferred taxes and rate base) mandated consistent adjustments to the other elements. Because the adjustment made by the utilities was solely with respect to rate base, the remaining three elements were unadjusted and thus "out of sync" under the consistency rules.
