Income Tax Disclosure [Abstract]

Schedule of Effective Income Tax Rate Reconciliation

The Registrants reported the following effective tax rates:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
CenterPoint Energy (1)	46	%	22	%	29	%	26	%
Houston Electric (2)	21	%	21	%	22	%	21	%
CERC (3) (4)	20	%	4	%	22	%	23	%

(1)CenterPoint Energy’s higher effective tax rate for the three and six months ended June 30, 2023 compared to the same periods ended June 30, 2022 was primarily due to tax impacts of the sale of Energy Systems Group which is partially offset by the absence of the non-deductible goodwill associated with the sale of the Natural Gas businesses in Arkansas and Oklahoma in 2022.

(2)Houston Electric’s higher effective tax rate for the six months ended June 30, 2023 compared to the same period in 2022 was primarily driven by an increase in state income taxes.

(3)CERC’s higher effective tax rate for the three months ended June 30, 2023 compared to the same period ended June 30, 2022 was primarily driven by the increase in income from continuing operations in 2023 while favorable permanent tax adjustments and EDIT amortization remained consistent.

(4)CERC’s lower effective tax rate for the six months ended June 30, 2023 compared to the same period ended June 30, 2022 was primarily driven by decreased amortization of the EDIT regulatory liability.
