Note 9 - Income Taxes

The tax effects of temporary differences that give rise to deferred tax assets are as follows:

A reconciliation of the statutory federal income tax rate to the Company's effective tax rate is as follows:

The income tax provision consists of the following:

The Company assesses the likelihood that deferred tax assets will be realized. To the extent that realization is not more-likely-than-not, a valuation allowance is established.  Based upon the Company's losses since inception, management believes that it is more-likely-than-not that future benefits of deferred tax assets will not be realized. Therefore, the Company established a full valuation allowance as of December 31, 2019 and 2018. As of December 31, 2019 and 2018, the change in valuation allowance was $3,169,100 and $3,781,485, respectively. 

The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions, principally California and New Jersey. The Company is subject to examination by the various taxing authorities.  The Company's federal and state income tax returns for tax years beginning in 2014 remain subject to examination.

At December 31, 2019 and 2018, the Company had approximately $43,000,000 and $32,000,000, respectively, of federal and state net operating loss carryovers that may be available to offset future taxable income.   The Company's 2017 and prior federal and state net operating loss carry forwards, if not utilized, will begin to expire from 2029 to 2038. Beginning with 2018, and for subsequent years, the Company's NOLs will have indefinite lives for federal tax purposes. In accordance with Section 382 of the Internal Revenue Code, the usage of the Company's net operating loss carryforward could be limited in the event of a change in ownership. At this time, the Company has not completed a full study to assess whether an ownership change under Section 382 of the Code occurred due to the costs and complexities associated with such a study.
