Federal Tax Law Investigation
The new federal law reduced the corporate tax rate for most investor-owned utilities from 35 percent to 21 percent. Utilities that pay federal income taxes may recover them through rates on a dollar-for-dollar basis.
The OUCC is participating on behalf of Indiana consumers. All rate-regulated, investor-owned utilities are parties to the case. Municipal and not-for-profit utility rates are not at issue.
The investigation has two phases:
- Immediate rate relief
- Longer term tax issues
PHASE ONE: IMMEDIATE RATE RELIEF
Rates for most Indiana utilities have decreased to reflect the federal corporate income tax reduction utilities received on January 1, 2018. More specifically, tariffs have been adjusted to reflect the new 21 percent rate.
PHASE TWO: LONGER TERM TAX ISSUES
The case's second phase is examining longer term issues including customer credits for rates collected at the 35-percent tax rate since January 1, 2018 and deferred income tax accounting matters.
Each utility's Phase Two issues are being considered in separate subdockets, with links to each case file below. Commission orders have been issued in most of the subdockets. Matters for the following utilities are still pending:
- American Suburban Utilities: Litigated case now in final stages.
- Indiana American Water Co.: Litigated case now in final stages.
- NIPSCO Electric: Being addressed in the utility's pending rate case, as agreed to by the parties.
