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, 2019. The results of operations for the three months ended March 31, 2020 are not necessarily indicative of the results to be expected for the full year.
Reclassification	ReclassificationAs of March 31, 2020, Financing lease right-of-use assets and liabilities, previously included in Deferred charges and other assets, net and Other long term liabilities, respectively, in the Condensed Consolidated Balance Sheets, are disclosed as separate line items in the Condensed Consolidated Financial Statements. Certain of these amounts previously reported in the Company's Condensed Consolidated Financial Statements and those respective footnotes for prior periods have been reclassified to conform to the 2020 presentation.
Interim Impairment Assessment	Interim Impairment Assessment The global crisis resulting from the spread of the recent novel coronavirus (“COVID-19”) has had a substantial impact on the economy and overall consumer demand for energy and hydrocarbon products. As a result of the significant decrease in PBF Energy’s stock price as of the end of the quarter and noticeable reduction in demand for the Company’s products, 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, 2020. 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 life.
New Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2016, the FASB issued Accounting Standard Update (“ASU”) 2016-13, “Financial Instruments-Credit Losses” (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). This guidance amends the guidance on measuring credit losses on financial assets held at amortized cost. ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted this ASU effective January 1, 2020. The adoption of this ASU does not currently impact the Company’s Condensed Consolidated Financial Statements. Refer to “Note 3 - Current Expected Credit Losses” for further disclosure related to our adoption of this pronouncement.. Recently Issued Accounting Pronouncements In March 2020, the FASB issued 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 for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this ASU are elective and apply to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference London Interbank Offering Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. The amendments in this ASU are effective for all entities as of March 12, 2020 through December 31, 2022. An entity may elect to apply the amendments for contract modifications by topic or industry subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. The Company is currently evaluating the impact of this new standard on its Condensed Consolidated Financial Statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-14, “Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20)”, to improve the effectiveness of benefit plan disclosures in the notes to financial statements by facilitating clear communication of the information required by GAAP that is most important to users of each entity’s financial statements. The amendments in this ASU modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Additionally, the amendments in this ASU remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The amendments in this ASU are effective for fiscal years ending after December 15, 2020, for public business entities and early adoption is permitted for all entities. The Company is currently evaluating the impact of this new standard on its Condensed Consolidated Financial Statements and related disclosures.
