Income Tax Disclosure [Abstract]  



At April 30, 2021, the Company had federal and state net operating loss carryforwards of approximately $47,902,000 and $44,165,000, respectively, available to offset against future taxable income; these operating loss carryforwards expire in 2020 through 2038.


Current tax laws limit the amount of loss available to be offset against future taxable income when a substantial change in ownership occurs. Therefore, the amount available to offset future taxable income may be limited. Based on the assessment of all available evidence including, but not limited to, the Company’s limited operating history in its core business and lack of profitability, uncertainties of the commercial viability of its technology, the impact of government regulations and healthcare reform initiatives and other risks normally associated with biotechnology companies, the Company has concluded that is more likely than not that these operating loss carryforwards will not be realized. Accordingly, 100% of the deferred tax valuation allowance has been recorded against these assets.


Deferred income taxes reflect the net effect of temporary differences between the financial reporting carrying amounts of assets and liabilities and income tax carrying amounts of assets and liabilities. The components of the Company’s deferred tax assets and liabilities are as follows:


    April 30,  
    2021     2020  
Deferred tax assets:                
Net operating loss carryforwards   $ 13,804,439       12,904,396  
Stock compensation     2,547,274       2,494,586  
Other     146,486       129,976  
Total deferred tax assets     16,498,199       15,528,958  
Valuation allowance     (16,498,199 )     (15,528,958 )
    $     $  


For all years presented, the Company did not recognize any deferred tax assets or liabilities. The net change in valuation allowance for the years ended April 30, 2021 and 2020 were increases of $969,241 and $1,341,187, respectively.


The provision for income taxes differs from the provision computed by applying the Federal statutory rate to net loss before income taxes as follows:


    Years Ended April 30,  
    2021     2020  
Federal benefit at statutory rate   $ (745,760 )     (803,646 )
State income taxes, net of Federal taxes     (303,631 )     (327,199 )
Permanent differences     78,258       248,908  
Provision related to change in valuation allowance     969,241       1,341,187  
Net valuation allowance for state tax deductions           (402,882 )
Other, net     1,892       (56,368 )
    $     $  


There have been no changes to the Company’s liability for unrecognized tax benefits during the year ended April 30, 2021.


The Company files its income tax returns in the U.S. Federal jurisdiction and various state jurisdictions. As of the year ended April 30, 2021, the tax returns for 2015 through 2020 remain open to examination by the Internal Revenue Service and various state tax authorities.


The Company’s policy is to recognize any interest and penalties related to unrecognized tax benefits as a component of income tax expense. As of the years ended April 30, 2021 and 2020, the Company had accrued no interest or penalties related to uncertain tax positions.
