Income Tax Disclosure [Abstract]
Income Taxes	Note 7 – Income Taxes Income taxes are provided for the tax effects of transactions reported in the consolidated financial statements and primarily consist of taxes currently due, plus deferred taxes. The Company recognizes deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns using current tax rates. The Company and its domestic subsidiaries file a consolidated federal income tax return. Deferred tax assets and liabilities are measured using the rates expected to apply to taxable income in the years in which the temporary differences are expected to reverse and the credits are expected to be used. The effect on deferred tax assets and liabilities of the change in tax rates is recognized in income in the period that includes the enactment date. All available evidence, both positive and negative, is considered to determine whether, based on the weight of that evidence, the Company is more likely than not to realize the benefit of a deferred tax asset and whether a valuation allowance is needed for some portion or all of a deferred tax asset. No such valuation allowances were recorded as of March 31, 2021 and September 30, 2020. The Company’s income tax provision is based on management’s estimate of the effective tax rate for the full year. The tax provision in any period will be affected by, among other things, permanent, as well as temporary differences in the deductibility of certain items, in addition to changes in tax legislation. As a result, the Company may experience significant fluctuations in the effective book tax rate (that is, its tax expense divided by pre-tax book income) from period to period. The Company’s effective tax rates for the quarters and six months ended March 31, 2021 and March 31, 2020 reflect the impact of the reduced rates under the U.S. Tax Cuts and Jobs Act (the “Tax Reform Act) which was signed into law on December 22, 2017.
