Income Tax Disclosure [Text Block]	NOTE 12 - INCOME TAXES At June 30, 2020, the Company had federal net operating loss carry-forwards ("NOLs") of approximately $2,639,000. These NOLs may be used to offset future taxable income and thereby reduce or eliminate our federal income taxes otherwise payable. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Ultimate utilization of such NOLs and research and development credits is dependent upon the Company's ability to generate taxable income in future periods and may be significantly curtailed if a significant change in ownership occurs. During the three months ended June 30, 2020, the Company generated approximately $116,000 of the net operating losses, and expects to utilize the NOL's before expiration. The effective rates were approximately 32% and 20% for the three months ended June 30, 2020 and 2019, respectively.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
