Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial information furnished herein reflects all adjustments (consisting of normal recurring accruals) which are, in the opinion of management, considered necessary for a fair presentation of the financial position and the results of operations and cash flows of the Company for the periods presented. All intercompany accounts and transactions have been eliminated in consolidation. These unaudited Condensed Consolidated Financial Statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. These interim Condensed Consolidated Financial Statements should be read in conjunction with the PBF Holding and PBF Finance financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2020. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the full year.
Interim Impairment Assessment	Interim Impairment Assessment The global crisis resulting from the spread of the COVID-19 pandemic continues to have a substantial impact on the economy and overall consumer demand for energy and hydrocarbon products. As a result of the sustained decrease in such demand which has resulted in sustained throughput reductions across the Company’s refineries, the Company determined an impairment triggering event had occurred. As such, the Company performed an interim impairment assessment on certain long-lived assets as of March 31, 2021. As a result of the interim impairment test, the Company concluded that the carrying values of its long-lived assets were not impaired when comparing the carrying value of the long-lived assets to the estimated undiscounted future cash flows expected to result from use of the assets over their remaining estimated useful lives. If adverse market conditions persist or there is further deterioration in the general economic environment due to the COVID-19 pandemic, there could be additional indicators that the Company’s assets are impaired requiring evaluation that may result in future impairment charges to earnings.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the effects of reference rate reform on financial reporting”. The amendments in this ASU provide optional guidance to alleviate the burden in accounting for reference rate reform, by allowing certain expedients and exceptions in applying GAAP to contracts, hedging relationship and other transactions affected by the expected market transition from London Interbank Offered Rate and other interbank rates. The amendments in this ASU are effective for all entities at any time beginning on March 12, 2020 through December 31, 2022 and may be applied from the beginning of an interim period that includes the issuance date of the ASU. The Company does not expect that the adoption of this guidance will have a material impact on its Consolidated Financial Statements and related disclosures.
