The Company had U.S. federal net operating loss (“NOL”) carryforwards of $32,654,129 and $21,556,006 for the years ended December 31, 2024 and 2023, respectively, which may be available to offset future taxable income. Federal NOL carryforwards generated in 2017 and prior of $38,297 will expire beginning in 2036. The remaining federal NOL carryforwards generated in 2018 and later do not expire. However, they are subject to the 80% limitation when utilized. The Company also had U.S. state NOL carryforwards of $32,217,433 and $21,415,201 for the years ended December 31, 2024 and 2023, respectively, which may be available to offset future taxable income and will expire beginning in 2036.

The Company had U.S. federal research and development tax credit carryforwards of $549,780 and $549,780 for the years ended December 31, 2024 and 2023, respectively, available to reduce future income tax liabilities. These will expire beginning in 2042. The Company also had U.S. state research and development tax credit carryforwards of $495,079 and $495,079 for the years ended December 31, 2024 and 2023, respectively, available to reduce future income tax liabilities. Of the U.S. state research and development tax credit carryforwards, $7,013 have an indefinite carryforward and the remainder expire beginning in 2036.

The Company has recorded a full valuation allowance against its net deferred tax assets as of December 31, 2024 and 2023, because the Company has determined that is it more likely than not that these assets will not be fully realized due to the significant uncertainty about the realization of the deferred tax asset until the Company can operate profitably. The Company experienced a net change in valuation allowance of $3,471,485 and $5,506,039 in the years ended December 31, 2024 and 2023, respectively.

(14) Income Taxes (continued)

Under the provisions of the Internal Revenue Code, the NOL and tax credit carryforwards are subject to review and possible adjustment by the Internal Revenue Service and state tax authorities. NOL and tax credit carryforwards may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest of significant stockholders over a three-year period in excess of 50%, as defined under Sections 382 and 383 of the Internal Revenue Code as well as similar state provisions. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities. The amount of the annual limitation is determined based on the value of the Company immediately prior to the ownership change. Subsequent ownership changes may further affect the limitation in future years. The Company has completed financings since its inception which may have resulted in a change in control as defined by Sections 382 and 383 of the Internal Revenue Code, or could result in a change in control in the future. The Company has not analyzed the historical or potential impact of its financings on beneficial ownership, and therefore, no determination has been made whether the net operating loss carryforward is subject to any Internal Revenue Code Section 382 limitation. To the extent there is a limitation, there could be a reduction in the deferred tax asset with an offsetting reduction in the valuation allowance.

The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company is subject to examination by federal and state jurisdictions, where applicable. The Company’s tax years from 2020 to the present remain open for review. All open years may be examined to the extent that tax credits or NOL carryforwards are used in future periods. The Company will recognize interest and penalties related to uncertain tax positions in income tax expense. As of December 31, 2024 and 2023, the Company had no accrued interest or penalties related to uncertain tax positions and no amounts have been recognized in the Company’s statements of operations.

A reconciliation of the Company’s unrecognized tax benefits is as follows (in thousands):

Due to the Company’s valuation allowance, the $0.2 million of unrecognized tax benefits would not affect the effective tax rate, if recognized. It is the Company’s practice to recognize interest and penalties related to income tax matters in income tax expense. As of December 31, 2024, we had no accrued interest and penalties related to uncertain tax positions. We do not expect any material changes to the estimated amount of liability associated with the Company’s uncertain tax positions within the next 12 months.

The Protecting Americans from Tax Hikes Act of 2015 (“PATH Act”) made permanent the federal credit for increasing research activities (“R&D credit”). The PATH Act also included a provision that allowed a qualified small business to utilize a portion of its annual R&D credit as a payroll tax offset of up to $250,000 of the FICA payroll tax. The Company qualifies for this provision and has recorded payroll tax prepayments of $250,000 and $172,492 for 2022 and 2021, respectively. These benefits were able to be used beginning in the first quarter of 2023 and do not expire. The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law in 2020 and contained several new or changed income tax provisions. The Company has evaluated the tax provisions of the CARES Act and determined the impact to be either immaterial or not applicable. The Inflation Reduction Act of 2022 modified the PATH Act by adding an additional payroll tax offset of up to $250,000 against the Medicare payroll tax beginning in 2023. The Company is evaluating the benefits available under this provision.

Due to The Tax Cuts and Jobs Act of 2017 (TCJA), there was a change in the deductibility of research and experimental expenditures that took effect for taxable periods beginning after December 31, 2021. Prior to January 1, 2022, the Company expensed research and experimental expenditures under Section 174(a) in the year that it recognized the expense for financial reporting. The Company has adopted Section 174(b) for taxable years 2022 and beyond. Domestic and foreign research and experimental expenditures will be capitalized and amortized over periods no less than 60 months and 180 months, respectively.

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.
