Income Taxes

DPL's provision for income taxes is based on the estimated annual effective tax rate, plus discrete items. The effective tax rate for the three months ended March 31, 2022 and 2021 was (31.6)% and (3.8)%, respectively. The year-to-date rate is different from the combined federal and state statutory rate of 22.1% primarily due to the flowthrough of the net tax benefit related to the reversal of excess deferred taxes of AES Ohio as a percentage of pre-tax book income.

DPL's income tax expense for the three months ended March 31, 2022 was calculated using the estimated annual effective income tax rate for 2022 of (34.8)% on ordinary income. Management estimates the annual effective tax rate based on its forecast of annual pre-tax income or loss.

AES files federal and state income tax returns which consolidate DPL and its subsidiaries. Under a tax sharing agreement with AES, DPL is responsible for the income taxes associated with its own taxable income and records the provision for income taxes using a separate return method.
