At September 30, 2021, net unrecognized tax benefits were $20 million, compared to $19 million at December 31, 2020. The Corporation anticipates that it is reasonably possible that final settlement of federal and state tax issues will result in a change in net unrecognized tax benefits of $4 million within the next twelve months. Included in accrued expenses and other liabilities on the Consolidated Balance Sheets was a liability for tax-related interest and penalties of $6 million at both September 30, 2021 and December 31, 2020.
Net deferred tax liabilities were $34 million at September 30, 2021, compared to $4 million of net deferred tax assets at December 31, 2020. The $38 million decrease resulted primarily from a decrease to deferred tax assets related to the allowance for loan losses and an increase to deferred tax liabilities related to defined benefit plans that was partially offset by decreases to deferred tax liabilities related to unrealized losses on investment securities available-for-sale as well as hedging gains and losses and an increase to deferred tax assets related to defined benefit plan components of other comprehensive
income. Included in deferred tax assets at both September 30, 2021 and December 31, 2020 were $3 million of state net operating loss carryforwards, which expire between 2021 and 2030. The Corporation believes that it is more likely than not that the benefit from certain of these state net operating loss carryforwards will not be realized and, accordingly, maintained a valuation allowance of $3 million at both September 30, 2021 and December 31, 2020. The determination regarding valuation allowance was based on evidence of loss carryback capacity, projected future reversals of existing taxable temporary differences to absorb the deferred tax assets and assumptions made regarding future events.
In the ordinary course of business, the Corporation enters into certain transactions that have tax consequences. From time to time, the Internal Revenue Service (IRS) or other tax jurisdictions may review and/or challenge specific interpretive tax positions taken by the Corporation with respect to those transactions. The Corporation believes its tax returns were filed based upon applicable statutes, regulations and case law in effect at the time of the transactions. The IRS or other tax jurisdictions, an administrative authority or a court, if presented with the transactions, could disagree with the Corporation’s interpretation of the tax law.
Based on current knowledge and probability assessment of various potential outcomes, the Corporation believes that current tax reserves are adequate, and the amount of any potential incremental liability arising is not expected to have a material adverse effect on the Corporation’s consolidated financial condition or results of operations. Probabilities and outcomes are reviewed as events unfold, and adjustments to the reserves are made when necessary.
