Income Tax Disclosure [Abstract]
Income Taxes	5. Income Taxes At the end of each interim period, we make our best estimate of the effective tax rate and the impact of discrete items, if any, and adjust the rate as necessary. The Company recorded income tax expense of $0.2 million and $12.8 million for the three and nine months ended September 30, 2020, respectively, resulting in effective tax rates of (16.7) percent and 51.0 percent, respectively, as compared to the 21.0 percent federal statutory rate. The difference between the Company's effective tax rate and the federal statutory rate during the three months ended September 30, 2020 was primarily the result of state tax rates. Differences between the Company's effective tax rates and the federal statutory rate during the nine months ended September 30, 2020 were primarily driven by the revaluation of certain deferred tax assets due to lower apportioned state tax rates, which resulted in $6.5 million of deferred income tax expense. Additionally, the new tax law passed in response to the novel coronavirus ("COVID-19"), the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act, which was enacted March 27, 2020, allows the Company to carry back net operating losses generated in 2019 to each of the five years preceding 2019. As a result, SunCoke expects to receive income tax refunds of approximately $4.8 million for prior year taxes paid and recorded a tax benefit of $1.5 million during the nine months ended September 30, 2020. The Company recorded income tax benefit of $63.5 million and $57.3 million for the three and nine months ended September 30, 2019, respectively, resulting in effective tax rates of (28.0) percent in both periods, as compared to the 21.0 percent federal statutory rate. This tax benefit was the result of the impairment charges recorded to our Logistics assets, which resulted in a $68.7 million decrease to the related deferred tax liabilities on the Consolidated Balance Sheets. Differences between the Company's effective tax rates and the statutory rate during the three and nine months ended September 30, 2019 were primarily due to the impact of state income taxes.
