Income Tax Disclosure [Text Block]	NOTE 6. INCOME TAXES On a quarterly basis, we estimate what our effective tax rate will be for the full fiscal year and record a quarterly income tax provision based on the anticipated rate. As the year progresses, we refine our estimate based on the facts and circumstances, including discrete events, by each tax jurisdiction. Our effective tax rate for the three months ended March 31, 2021 and 2020 was 31% and 18%, respectively. On March 11, 2021, the American Rescue Plan Act (“ARPA”) was signed and includes several provisions, such as measures that extend and expand the Employee Retention Credit (“ERC”), previously enacted under the Coronavirus Aid, Relief and Economic Security Act, through December 31, 2021. Companies who have received PPP are not precluded from this program. We are still in the process of reviewing but believe we meet the criteria for revenue reduction and the number of monthly average employees, which qualifies us for the credit. For the three months ended March 31, 2021, we did not record a benefit related to the ERC. We plan to apply for the credit, however we are still completing the computation. This is not tax deductible and is thus included in our calculation of the 2021 tax rate.
