Subsequent Events [Abstract]
Subsequent Events	24. Subsequent Events The Company has evaluated events that have occurred subsequent to December 31, 2023 and through May 10, 2024, the date of the filing of this report. Effective January 1, 2024, MSCO changed its name from Muriel Siebert & Co., Inc. to Muriel Siebert & Co., LLC, and SNXT changed its name to from Siebert AdvisorNXT, Inc. to Siebert AdvisorNXT, LLC with their tax status changing from C-Corporations to LLCs under state law. Starting in 2024, both MSCO and SNXT are single member limited liability companies that will be treated as disregarded entities for tax purposes. As such, both MSCO and SNXT will no longer be subject to direct taxation and will be disregarded by the relevant tax authorities. The guidance in Accounting Standards Update 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes specifies that an entity is not required to allocate income tax provision to a legal entity that is both not subject to tax and disregarded by the taxing authority, but an entity may elect to do so. MSCO and SNXT are not making the available election to allocate income taxes. Accordingly, on a prospective basis, MSCO and SNXT will no longer record current or deferred income taxes. On January 18, 2024, STCH entered into a Purchase Agreement (the “Purchase Agreement”) with J2 Financial Technology, Inc., d/b/a “Guild”, a Delaware corporation. Under the Purchase Agreement, STCH purchased a mobile self-directed trading app for the total purchase price of $385,000. The purchase price consisted of 200,000 restricted shares of the Company’s common stock (priced at the historical 30-day moving average as of January 18, 2024) worth approximately $350,000 and $35,000 cash. On April 18, 2024, the Company received a notification from Nasdaq Regulation that the Company no longer complies with Nasdaq’s Listing Rules (the “Nasdaq Rules”) for continued listing, as a result of the Company’s failure to file this Report. The Company expects to regain compliance with the Nasdaq Rules in connection with the filing of this Report on May 10, 2024. However, since this Report was filed after its scheduled due date, the Company will no longer satisfy the eligibility requirement for use of registration statements on Form S-3, which requires that the Company file in a timely manner all reports required to be filed during the prior twelve calendar months. As a result, the Company has suspended use of its registration statements on Form S-3 (333-276585 and 333-262895), and will no longer be able to use its registration statements or access its At the Market program. Refer to Siebert’s Current Report on Form 8-K filed on April 24, 2024 for more information. Based on the Company’s assessment, other than the events described above, there have been no material subsequent events that occurred during such period that would require disclosure in this report or would be required to be recognized in the consolidated financial statements as of December 31, 2023.
