|Income Taxes [Abstract]|
|Income Taxes||11. Income Taxes On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) was enacted and signed into law in response to the market volatility and instability resulting from the COVID-19 pandemic. It includes a significant number of tax provisions and lifts certain deduction limitations originally imposed by the Tax Cuts and Jobs Act of 2017 (the 2017 Act). The changes are mainly related to: (1) the business interest expense disallowance rules for 2019 and 2020; (2) net operating loss rules; (3) charitable contribution limitations; (4) employee retention credit; and (5) the realization of corporate alternative minimum tax credits. The Company does not anticipate the application of the CARES Act provisions to materially impact the overall Consolidated Financial Statements. For the years ended December 31, 2021 and 2020 the provisions for income taxes were as follows: 2021 2020Federal – current$ — $ —State – current — —Foreign – current — —Total$ — $ — Under ASC 740, deferred income tax assets and liabilities reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of our net deferred tax assets and liabilities as of December 31, 2021 and 2020 are as follows: 2021 2020Deferred tax assets (liabilities): Net operating loss carryforwards$ 16,915,000 $ 14,881,000Stock based compensation 4,372,000 4,094,000Accrued compensation 31,000 19,000Depreciation and amortization 3,783,000 3,867,000Other 2,000 —Total deferred tax assets 25,103,000 22,861,000Valuation allowance for net deferred tax assets (25,103,000) (22,861,000)Total$ — $ — The Company has provided a valuation allowance against deferred tax assets recorded as of December 31, 2021 and 2020 due to uncertainties regarding the realization of such assets. The net change in the total valuation allowance for the year ended December 31, 2021 was an increase of approximately $2,479,000. The net change in the total valuation allowance for the year ended December 31, 2020 was an increase of approximately $568,000. In assessing the valuation of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. The Company considers projected future taxable income and planning strategies in making this assessment. Based on the level of historical operating results and projections for the taxable income for the future, the Company has determined that it is more likely than not that the deferred tax assets will not be realized. Accordingly, the Company has recorded a valuation allowance to reduce deferred tax assets to zero. There can be no assurance that the Company will ever be able to realize the benefit of some or all of the federal and state loss carryforwards, either due to ongoing operating losses orf due to ownership changes, which limit the usefulness of the loss carryforwards. As of December 31, 2021, the Company has available net operating loss carryforwards of approximately $64,000,000 for federal income tax purposes, which will start to expire in 2026. The net operating loss carryforwards for state purposes are approximately $61,000,000 and will start to expire in 2028. The difference between the provision for income taxes and income taxes computed using the U.S. federal income tax rate for the years ended December 31, 2021 and 2020 was as follows: 2021 2020Computed expected tax expense$ (1,735,000) $ (613,000)State taxes, net of federal benefit (799,000) (141,000)Expiration of NOL carryforwards 87,000 44,000Other (32,000) 142,000Change in valuation allowance 2,479,000 568,000Total$ — $ — The Company has determined that during 2010 it experienced a “change of ownership” as defined by Section 382 of the Internal Revenue Code. As such, utilization of net operating loss carryforwards and credits generated before the 2010 change in ownership will be limited to approximately $207,000 per year until such carryforwards are fully utilized. The pre change net operating loss carryforward was approximately $6,000,000. Since 2010 the Company has not conducted a study to assess whether a change of control has occurred or whether there have been multiple changes of control since inception due to the significant complexity and cost associated with such a study. If the Company has experienced a change of control, as defined by Section 382, at any time since 2010, utilization of the net operating loss carryforwards tax credit carryforwards would be subject to further annual limitation under Section 382. Any limitation may result in expiration of a portion of the net operating loss carryforwards before utilization. The Company files income tax returns in the U.S. federal jurisdiction, Arizona, and California. Because the Company is carrying forward federal and state net operating losses from 2006, the Company is subject to U.S. federal and state income tax examinations by tax authorities for all years since 2006. The Company does not have a liability for any uncertain tax positions. As of December 31, 2021, no accrued interest or penalties are recorded in the financial statements.|
