Accounting Policies [Abstract]
Revenue [Policy Text Block]	Revenue Recognition The majority of our revenue is derived from short-term sales contracts. We account for revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers”. Revenue for our products is recognized at the time in which our performance obligation is satisfied which we have defined as “control” of the product by the customer. “Control” is defined as a customer having “rights/obligations of physical control over the product or has the rights and intention to control the product.” Based on the terms of our contracts, a customer’s “control” is based on analysis of the following; (i) when a customer arranges their own shipping, and once the product has left our dock, Amerityre Corporation (“Amerityre” or the “Company”) recognizes revenue for the product. In effect by arranging their own shipping the customer is “taking control” of the product when it leaves our warehouse; or (ii) when a customer does not arrange their own shipping, we cannot recognize revenue until it is delivered and the customer takes “control” of the product. This establishes a “deferred revenue” event until such time as delivery of the product has been completed and we have proof from the shipper of the delivery (and change in control). Deferred revenue was $42,125, inclusive of $45 of shipping and handling revenue (see below), as of September 30, 2021. Deferred revenue was $17,667, inclusive of $1,633 of shipping and handling revenue (see below), as of September 30, 2020.
Shipping and Handling Cost, Policy [Policy Text Block]	Shipping and Handling Shipping and Handling Fees require that freight costs charged to customers be classified as revenues. Freight expenses are included in costs of sales and are recognized as incurred. Due to our adoption of ASC 606 as discussed above, we defer the revenues of shipping and handling until the related revenue is also recognized. The result of this accounting is a deferral of $45 as of September 30, 2021 and $1,633 as of September 30, 2020.
Earnings Per Share, Policy [Policy Text Block]	Basic and Fully Diluted Net Income (Loss) Per Share Basic and Fully Diluted net income (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Our outstanding stock options have been excluded from the basic and fully diluted net income per share calculation. We excluded 1,030,000 and 2,870,000 common stock equivalents for the quarters ended September 30, 2021 and 2020, respectively, because they are anti-dilutive.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants, and the SEC, did not, or are not believed by management to, have a material impact on the Company's present or future financial position, results of operations or cash flows.
