For the year ended December 31, 2023, income tax expense was impacted by a change in Wisconsin state income tax law associated with the exclusion of interest income on certain Wisconsin-based business or agriculture purpose loans. The impact of this tax law change was a one-time $9.1 million charge to state income tax expense in 2023, but moving forward Nicolet will experience a reduction / elimination of state income taxes being recognized.
A valuation allowance is required if it is more likely than not that some portion of the deferred tax asset will not be realized. The remaining valuation allowance as of December 31, 2025, of $18 million is the effect of the previously discussed Wisconsin tax law change on the state related net of tax attributes, along with the state related impact of changes to the unrealized losses on AFS securities disposed.
At December 31, 2025, the Company had a federal and state net operating loss carryforward of $3 million and $16 million, respectively, resulting from the Company’s acquisitions. These carryforwards are subject to the IRC section 382 limitation calculation and are limited in the overall amount expected to be realized. Additionally, due to the 2023 Wisconsin tax law change, the Company has accumulated a State loss carryforward of $151 million, for which a valuation allowance has been recognized.

About Income Taxes Disclosures

The income tax disclosure reveals how much a company actually pays in taxes versus what the statutory rate would predict. Analysts focus on the effective tax rate (ETR) reconciliation, which breaks down every item driving the gap between the 21% federal rate and the company's reported ETR — including R&D credits, foreign rate differentials, and state taxes. Deferred tax assets (DTAs) and their valuation allowances signal management's confidence in future profitability: a rising allowance suggests the company doubts it can use accumulated tax benefits. Uncertain tax benefit (UTB) reserves quantify exposure to IRS challenges on aggressive positions.

Key signals to watch: sudden ETR drops without clear operational reasons, large increases in valuation allowances, growing UTB balances, and significant unremitted foreign earnings. Post-TCJA, pay attention to GILTI and BEAT provisions that affect multinational tax structures. Compare the cash taxes paid (from the cash flow statement) against the income tax provision to gauge earnings quality.
