Notes to Financial Statements
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	1. BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Business Activities Ironstone Group, Inc. and subsidiaries have no operations but are seeking appropriate business combination opportunities. Ironstone Group, Inc, (“Ironstone” or the “Company”) a Delaware corporation, was incorporated in 1972. Principles of Consolidation The accompanying consolidated financial statements include the accounts of Ironstone Group, Inc. and its subsidiaries, AcadiEnergy, Inc., Belt Perry Associates, Inc., DeMoss Corporation, and TaxNet, Inc. (collectively the “Company”). All significant intercompany accounts and transactions have been eliminated in consolidation. Marketable and Non-Marketable Securities Marketable and non-marketable securities have been classified by management as available for sale in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 320. Marketable securities are recorded at fair value and any unrealized gains and losses are excluded from earnings and reported as a separate component of shareholders’ equity until realized. The fair value of the Company’s marketable securities and investments at December 31, 2022 is based on quoted market prices. For the purpose of computing realized gains and losses, cost is identified on a specific identification basis. For marketable securities for which there is an other-than-temporary impairment, an impairment loss is recognized as a realized loss, and related adjustments are not made for recovery in value. Securities determined to be non-marketable by the Company do not have readily determinable fair values. The Company estimates the fair value of these instruments using various pricing models and the information available to the Company that it deems most relevant. Among the factors considered by the Company in determining the fair value of financial instruments are discounted anticipated cash flows, the cost, terms and liquidity of the instrument, the financial condition, operating results and credit ratings of the issuer or underlying company, the quoted market price of publicly traded securities with similar duration and yield, the Black-Scholes Options Valuation methodology adjusted for active market, the share price of recent round of financings by an outsider, and other considerations on a case-by-case basis and other factors generally pertinent to the valuation of financial instruments. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates made in the financial statements relate to the valuation of the Company’s non-marketable investments. Actual results could differ from those estimates. Income Taxes The Company and its wholly owned subsidiaries file a consolidated federal income tax return. Income taxes are provided for the tax effects of transactions reported in the financial statements and consist of taxes currently due plus deferred income taxes. Deferred income taxes are recognized for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future. Deferred income taxes are also recognized for net operating loss carryforwards that are available to offset future taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Ironstone follows the authoritative guidance on accounting for and disclosure of uncertainty in tax positions, which requires the Company to determine whether a tax position of Ironstone is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. For tax positions meeting the more likely than not threshold, the tax amount recognized in the financial statements is reduced by the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant taxing authority. The Company has determined that there is no effect on the financial statements from this authoritative guidance. The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company is subject to examination by federal, state, local, and foreign jurisdictions, where applicable. As of December 31, 2022, the tax years that remain subject to examination by the major tax jurisdictions under the statute of limitations is from the year 2019 2018 During the year ended December 31, 2022, the Company recognized and paid $1,035 of interest and penalties related to state income and franchise taxes in its statement of operations. Stock-Based Compensation Ironstone recognizes the fair value of stock options granted on a straight-line basis over the requisite service period of the option grant, which is the standard vesting term of four The full impact of stock-based compensation in the future is dependent upon, among other things, the total number of stock options granted, the fair value of the stock options at the time of grant and the tax benefit that Ironstone may or may not receive from stock-based expenses. Additionally, stock-based compensation requires the use of an option-pricing model to determine the fair value of stock option awards. This determination of fair value is affected by Ironstone’s stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, Ironstone’s expected stock price volatility over the term of the awards. Basic and Diluted Loss per Share Basic loss per share (“EPS”) excludes dilution and is computed by dividing net income (loss) applicable to common shareholders by the weighted average number of common shares actually outstanding during the period. Diluted EPS reflects the dilution from potentially dilutive securities, except where inclusion of such potentially dilutive securities would have an anti-dilutive effect, using the average stock price during the period in the computation and because of the net loss for the periods presented. Recent Accounting Pronouncements In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”). ASU 2014-15 introduces an explicit requirement for management to assess and provide certain disclosures if there is substantial doubt about an entity’s ability to continue as a going concern. ASU 2014-15 is effective for the annual period ending after December 15, 2016. The Company has adopted ASU 2014-15. In August 2018, the FASB issued Accounting Standards Update (“ASU”) 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement”. ASU 2018-13 removes certain disclosures, modifies others and introduces additional disclosure requirements for entities. The amendments in ASU 2018-13 for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted the new standard on January 1, 2020. The adoption did not have a material impact on the Company’s financial statements. Liquidity As reflected in the accompanying financial statements the Company has net losses and has a negative cash flow from operations. If necessary the Company may seek to sell additional debt or equity securities or enter into new credit facilities to meet its cash needs. The Company cannot make assurances that it will be able to complete any financing or liquidity transaction, that such financing or liquidity transaction will be adequate for the Company’s needs, or that a financing or liquidity transaction will be completed in a timely manner. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying financial statements do not include any adjustments relating to the recovery and classification of asset carrying amounts or the amount and classification of liabilities that might result should the Company be unable to continue as a going concern.

Long-Term Debt [Text Block]	5. NOTE PAYABLE On March 31, 2012, the Company received $1,000,000 from a third party and issued a related promissory note. The note carries an 8% interest rate, per annum, and has a maturity date of March 31, 2017. Interest accrues on the balance and converts to separate notes payable on a quarterly basis. The total amounts due under this agreement, including the notes related to accrued interest, are due in full at the end of the term.

The Company is subject to taxation in the U.S. and the state of California. As of December 31, 2022, the tax years that remain subject to examination by the major tax jurisdictions under the statute of limitations is from the year 2018 2017 At December 31, 2022, the Company had approximately $1,150,237 of net operating loss carryforwards resulting in a Federal deferred tax asset of $241,550 and a state tax asset of $101,681. It is possible that subsequent ownership changes may limit the utilization of these tax attributes. Approximately $295,266 of the federal net operating loss carryforwards will expire in year 2023 through 2042. The remainder of the federal net operating loss carryforwards generated in 2018 and later have indefinite carryforward periods however are limited to 80% of taxable income in any given year. The California net operating loss carryforwards will expire in year 2028 through 2041. Given there is uncertainty as to whether the Company will be profitable in the future, the tax asset is not recognized during 2022.
