RESEARCH FRONTIERS INC Income Taxes Disclosure
(6) Income Taxes
Since inception, the Company has incurred losses from operations and as a result has not recorded income tax expense. Benefits related to net operating loss carryforwards and deferred items have been fully reserved because it is not more likely than not that the Company will achieve profitable operations. The difference between the total income taxes at the federal statutory rate for each of the years ended December 31, 2025 and 2024 and the fact that income tax benefit was recorded in each of these years is attributable to the change in the valuation allowance recorded in each year.
The tax effects of temporary differences that give rise to significant portions of the deferred tax assets at December 31, 2025 and 2024 are presented below:

The reconciliation of income taxes at the federal statutory rate to our provision for (benefit from) income taxes for the year ended December 31, 2024, in accordance with the guidance prior to the adoption of ASU 2023-09 was as follows:
| 2024 | ||||
| Income tax provision at federal statutory rate | $ | (275,000 | ) | |

In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon future taxable income during the period in which those temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon its historical operating losses, utilization of deferred tax assets cannot currently be determined. Accordingly, the Company has recorded a full valuation allowance against the deferred tax assets due to the uncertainty regarding the future utilization of the deferred tax assets for all periods presented.
At December 31, 2025, the Company had net operating loss carryforwards for federal income tax purposes of approximately $56,479,000. Net operating loss carryforwards accumulated through December 31, 2017 of approximately $41,115,000 will expire in varying amounts from 2026 through 2037. Net operating losses generated since 2018, totaling approximately $15,364,000, will carry forward indefinitely, but cannot offset more than 80% of taxable income. Research and other credit carryforwards of approximately $788,000 are available to the Company to reduce income taxes payable in future years principally through 2043. The Company’s ability to utilize its net operating loss carryforwards and its current year tax credits in future periods could be subject to the 382 limitation. The Company will need to complete an analysis to determine whether its net operating losses are subject to the 382 limitation. At December 31, 2025, the Company had net operating loss carryforwards for state income tax purposes of approximately $2,693,000. State net operating loss carryforwards subject to expiration are $2,515,000 and $178,000 do not expire.
No cash was paid, in federal, state or foreign jurisdictions, for income taxes for the years ended December 31, 2025 and 2024.

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.
