Income Tax Disclosure [Abstract]  
Income Taxes INCOME TAXES:
The effective tax rates for the three months ended March 31, 2022 and 2021 were 26.1% and 27.6%, respectively. The effective tax rates for the three months ended March 31, 2022 and 2021 differ from the U.S. federal statutory rate of 21.0% primarily due to the impact of equity compensation and state taxes.

The total amount of uncertain tax positions at March 31, 2022 and December 31, 2021 was $67,805. If these uncertain tax positions were recognized, approximately $67,805 would affect CNX's effective tax rate at March 31, 2022 and December 31, 2021. There was no change to the unrecognized tax benefits during the three months ended March 31, 2022.

CNX recognizes accrued interest and penalties related to uncertain tax positions in interest expense and income tax expense, respectively. As of March 31, 2022 and December 31, 2021, CNX had no accrued liabilities for interest and penalties related to uncertain tax positions.
CNX and its subsidiaries file federal income tax returns with the United States and tax returns within various states. With few exceptions, the Company is no longer subject to United States federal, state, local, or non-U.S. income tax examinations by tax authorities for the years before 2018.
