Income Taxes	3 Months Ended
Income Taxes	Mar. 31, 2019
Income Taxes	INCOME TAXES (Entergy Corporation, Entergy Arkansas, Entergy Louisiana, Entergy Mississippi, Entergy New Orleans, Entergy Texas, and System Energy) See “Income Tax Audits” and “Other Tax Matters” in Note 3 to the financial statements in the Form 10-K for a discussion of income tax audits, the Tax Cuts and Jobs Act, and other income tax matters involving Entergy. The following are updates to that discussion. Tax Cuts and Jobs Act During the three months ended March 31, 2019, Entergy Arkansas, Entergy Louisiana, and Entergy Texas returned unprotected excess accumulated deferred income taxes, associated with the effects of the Tax Cuts and Jobs Act, to their customers through rate riders and other means approved by their respective regulatory commissions. Return of the unprotected excess accumulated deferred income taxes results in a reduction in the regulatory liability for income taxes and a corresponding reduction in income tax expense. This has a significant effect on the effective tax rate for the period as compared to the statutory tax rate. For the three months ended March 31, 2019 the return of unprotected excess accumulated deferred income taxes reduced the Registrant Subsidiaries’ regulatory liability for income taxes as follows: Entergy Arkansas, $32 million; Entergy Louisiana, $7 million; and Entergy Texas, $22 million. Other Tax Matters In April 2019 the state of Arkansas enacted corporate income tax law changes that phase in an Arkansas tax rate reduction from 6.5% to 5.9% by the year 2022. The rate reduction will eventually reduce Entergy Arkansas’s combined federal and state applicable tax rate by 0.4% once fully adopted. The Arkansas tax law enactment also phases in an increase to the net operating loss carryover period from five to ten years. The adoption of these tax law changes throughout the phase-in period is not expected to have a significant effect on the financial position, results of operations, or cash flows of Entergy Arkansas, the Utility, or Entergy. Vermont Yankee The Vermont Yankee transaction resulted in Entergy generating a net deferred tax asset in January 2019. The deferred tax asset could not be fully realized by Entergy in the first quarter of 2019; accordingly, Entergy accrued a net tax expense of $29 million on the disposition of Vermont Yankee. See Note 16 to the financial statements herein for discussion of the Vermont Yankee transaction.
