At December 31, 2022, the Company has net operating loss carry forwards of approximately $57.3 million which may be used to offset future taxable income. The net operating loss carryforwards includes $42.8 million of losses arising prior to December 31, 2017 that expire in 2028 through 2037. Those arising in tax years after 2017 can be carried forward indefinitely. Also, for losses arising in taxable years beginning after December 31, 2017 the operating loss deduction is limited to 80% of taxable income (determined without regard to the deduction). Since the Company has not yet generated significant taxable income, a valuation allowance has been established to fully reserve the Company's net deferred tax assets at December 31, 2022. A change in ownership eliminated substantially all net operating loss carryforwards of an acquired subsidiary at July 26, 2019.
The Company recognizes the tax benefit or obligation from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based not only on the technical merits of the tax position based on tax law, but also past administrative practices and precedents of the taxing authority. The tax benefits or obligations are recognized in our financial statements if there is a greater than 50% likelihood of the tax benefit or obligation being realized upon ultimate resolution. As of the years ended December 31, 2022 and 2021, the Company had no uncertain tax positions that required recognition.
As of December 31, 2022, the Company's tax returns for years 2019 to 2021 remain subject to examination for both federal and state filings.
