Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and amounts used for income tax purposes. Significant components of the Company's deferred taxes as of December 31, 2020 and 2019 are as follows:

During the years ended December 31, 2020 and 2019, the Company recorded a valuation allowance equal to its net deferred tax assets. The Company determined that due to a recent history of net losses, that at this time, sufficient uncertainty exists regarding the future realization of these deferred tax assets through future taxable income. If, in the future, the Company believes that it is more likely than not that these deferred tax benefits will be realized, the valuation allowances will be reduced or eliminated. With a full valuation allowance, any change in the deferred tax asset or liability is fully offset by a corresponding change in the valuation allowance. At December 31, 2020 and 2019, the Company provided a valuation allowance on its net deferred tax assets of $6,654,890 and $5,675,082, respectively.

The Company has Federal net operating losses (“NOLs”) of approximately $9.3 million which begin to expire in the years beginning in 2033 and $10 million that do not expire. Pursuant to Section 382 of the Internal Revenue Code, use of the Company's NOLs and credit carry forwards may be limited if the Company experiences a cumulative change in ownership of greater than 50% in a moving three-year period.

The Company also has federal credits that begin to expire 2031 and state tax credits that may be carried forward indefinitely.

At December 31, 2020 and 2019, the Company had no material unrecognized tax benefits and no adjustments to liabilities or operations were required. The Company does not expect that its unrecognized tax benefits will materially increase within the next twelve months. The Company recognizes interest and penalties related to uncertain tax positions in interest expense. As of December 31, 2020, and 2019, the Company has not recorded any provisions for accrued interest and penalties related to uncertain tax positions.

In certain cases, the Company’s uncertain tax positions are related to tax years that remain subject to examination by the relevant tax authorities. The Company files federal and state income tax returns in jurisdictions with varying statutes of limitations. The 2017 through 2020 tax years generally remain subject to examination by federal and state tax authorities.
