Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of RCI Hospitality Holdings, Inc. (the “Company,” “RCIHH,” “we,” or “us”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP” or “U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q of Regulation S-X. They do not include all information and footnotes required by GAAP for complete financial statements. The September 30, 2023 consolidated balance sheet data were derived from audited financial statements but do not include all disclosures required by GAAP. However, except as disclosed herein, there has been no material change in the information disclosed in the notes to the consolidated financial statements for the year ended September 30, 2023 included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission on December 14, 2023. The interim unaudited condensed consolidated financial statements should be read in conjunction with those consolidated financial statements included in the Form 10-K. In the opinion of management, all adjustments considered necessary for a fair statement of the financial statements, consisting solely of normal recurring adjustments, have been made. Operating results for the six months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending September 30, 2024.
Recent Accounting Standards and Pronouncements	Recent Accounting Standards and Pronouncements In October 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This ASU amends Accounting Standards Codification ("ASC") Topic 805 to require acquiring entities to apply ASC 606 to recognize and measure contract assets and contract liabilities in business combinations. The ASU is effective for public entities for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. We adopted ASU 2021-08 on October 1, 2023. Our adoption of this ASU did not have a significant impact on our consolidated financial statements. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. The amendments in this ASU clarify that an entity should measure the fair value of an equity security subject to contractual sale restriction the same way it measures an identical equity security that is not subject to such a restriction. The FASB said the contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, should not affect its fair value. The ASU is effective for public entities for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted. We are evaluating the impact of this ASU and we believe that the adoption of this guidance will not have a significant impact on our consolidated financial statements. In March 2023, the FASB issued ASU 2023-01, Leases (Topic 842): Common Control Arrangements, which amends certain provisions of ASC 842 that apply to arrangements between related parties under common control. The ASU requires all companies to amortize leasehold improvements associated with common control leases over the asset's useful life to the common control group regardless of the lease term. It also allows private and certain not-for-profit entities to use the written terms and conditions of an agreement to account for common control leases without further assessing the legal enforceability of those terms. The guidance is effective for all entities in fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for both interim and annual financial statements that have not yet been made available for issuance. We are still evaluating the impact of this ASU but we believe that the adoption of this guidance will not have a significant impact on our consolidated financial statements. 2. Recent Accounting Standards and Pronouncements - continued In August 2023, the FASB issued ASU 2023-05, Business Combinations—Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement, which addresses the accounting for contributions made to a joint venture, upon formation, in a joint venture's separate financial statements. The objectives of the ASU are to (1) provide decision-useful information to investors and other allocators of capital in a joint venture's financial statements and (2) reduce diversity in practice. The FASB decided to require a joint venture to apply a new basis of accounting upon formation that will recognize and initially measure its assets and liabilities at fair value (with exceptions to fair value measurement that are consistent with the business combinations guidance). The amendments of this ASU are effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. Additionally, a joint venture that was formed before January 1, 2025 may elect to apply the amendments retrospectively if it has sufficient information. early adoptions is permitted in any interim or annual period in which financial statements have not yet been issued (or made available for issuance), either prospectively or retrospectively. We are still evaluating the impact of this ASU on our consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which aims to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments in the ASU enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity's overall performance and assess potential future cash flows. The ASU applies to all public entities that are required to report segment information in accordance with ASC 280, and is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We are evaluating the impact of this ASU on our consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. Under the ASU, public business entities must annually (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than five percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate. The amendments of the ASU are effective for public business entities for annual periods beginning after December 15, 2024. Entities are permitted to early adopt the standard for annual financial statements that have not been issued or made available for issuance. We are enhancing our income tax reporting system to be able to capture the required disclosures of this ASU.
