Income Taxes | Note 14: Income Taxes The Company files a consolidated federal income tax return. As of December 31, 2020 and 2019, retained earnings included approximately $17.5 million for which no deferred income tax liability had been recognized. This amount represents an allocation of income to bad debt deductions for tax purposes only for tax years prior to 1988. If the Bank were to liquidate, the entire amount would have to be recaptured and would create income for tax purposes only, which would be subject to the then-current corporate income tax rate. The unrecorded deferred income tax liability on the above amount was approximately $3.9 million at both December 31, 2020 and 2019, respectively. During the years ended December 31, 2020, 2019 and 2018, the provision for income taxes included these components: ​

​ The Company and its consolidated subsidiaries have not been audited recently by the Internal Revenue Service (IRS), except as described here. The Company, through one of its subsidiaries, is a partner in two partnerships which were under IRS examination for 2006 and 2007. As a result, the Company’s 2006 and subsequent tax years remained open for examination. The examinations of these partnerships were completed during 2019. The completion of these examinations did not result in significant changes to the Company’s tax positions. As a result, federal tax years through December 31, 2016 are now closed. The Company is currently under State of Missouri income and franchise tax examinations for its 2014 and 2015 tax years. The Company does not currently expect significant adjustments to its financial statements from this state examination.
