The Company has recorded a deferred tax asset for the future tax benefits of Iowa net operating loss carry-forwards.  The net operating loss carry-forwards are generated by the Company largely from its investment in tax credit real estate properties.  The Company is required to file a separate Iowa tax return and cannot be consolidated with the Bank.  The net operating loss carry-forwards will expire, if not utilized, between 2024 and 2042.  The Company has recorded a valuation allowance to reduce the deferred tax asset attributable to the net operating loss carry-forwards.  At December 31, 2023 and 2022, the Company believes it is more likely than not that the Iowa net operating loss carry-forwards will not be realized. A valuation allowance related to the remaining deferred tax assets has not been provided because management believes it is more likely than not that the results
of future operations will generate sufficient taxable income to realize the deferred tax assets. The valuation allowance increased by $99,000 and $93,000 for the years ended December 31, 2023 and 2022, respectively.

The net change in the deferred income taxes for the years ended December 31, 2023, 2022 and 2021 is reflected in the consolidated financial statements as follows:
