Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In assessing the realizability of deferred tax assets, the Company considers whether it is more-likely-than-not that some portion or all of its deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income or reversal of deferred tax liabilities during the periods in which those temporary differences become deductible. As a part of this evaluation, the Company assesses all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, the availability of tax carrybacks, tax-planning strategies, and results of recent operations (including cumulative losses in recent years), to determine whether sufficient future taxable income will be generated to realize existing deferred tax assets. On the basis of this evaluation, and after considering future reversals of existing taxable temporary differences and the effects of seasonality on the Company’s business, the Company determined that its U.S. federal deferred tax assets are more-likely-than-not to be realizable, but that valuation allowances of $1,144,000, $1,064,000 and $1,186,000 as of July 31, 2021, January 31, 2021 and July 31, 2020, respectively, are needed for certain state NOL’s to reduce the carrying amount of deferred tax assets to an amount that is more-likely-than-not to be realized. For the three months ended July 31, 2021 and 2020, the effective tax rates were 24.6% and 46.8%, respectively. For the six months ended July 31, 2021 and 2020, the effective tax rates were (36.7)% and 11.5%, respectively. Effective tax rates for the three months and six months ended July 31, 2021 and 2020 were primarily due to the change in forecasted mix of income before taxes in various jurisdictions, estimated permanent differences and the recording of a partial valuation allowance on net deferred tax assets. On March 27, 2020, the then President signed the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"). The Company has performed an analysis of the impact of the CARES Act and have determined that the impact would not be significant. The CARES Act provides single-employer pension companies additional time to meet the funding obligations. Consequently, the tax deduction related to such contributions will be deferred until the funding payment is made. The CARES Act also modifies the limitation for business interest expense deduction. The new limitation has increased from 30 to 50 percent of adjusted taxable income. The January 31, 2016 and subsequent years remain open for examination by the IRS and state tax authorities. The Company is not currently under any state examination. The Company is currently under IRS examination for its fiscal year ended January 31, 2016 Federal tax return.
