Our net deferred tax liability of $172,000 and $179,000 at June 30, 2025 and 2024, respectively, represents the excess of our indefinite-lived deferred tax liabilities over our indefinite-lived deferred tax assets, and are recorded in other non-current liabilities on the accompanying consolidated balance sheets at June 30, 2025 and 2024. Realization of deferred tax assets is dependent upon the generation of future taxable income. As required by ASC 740, we have evaluated the positive and negative evidence bearing upon our ability to realize the deferred tax assets as of June 30, 2025 and 2024. We have determined that it was more likely than not that Lantronix would not realize the deferred tax assets due to our cumulative losses and uncertainty of generating future taxable income.

We continue to assert that our foreign earnings are indefinitely reinvested in our overseas operations and as such, deferred income taxes were not provided on undistributed earnings of certain foreign subsidiaries. The 2017 Act created a requirement that certain income earned by foreign subsidiaries, known as global intangible low-tax income (“GILTI”), must be included in the gross income of their U.S. shareholder. The FASB allows an accounting policy election of either recognizing deferred taxes for temporary differences expected to reverse as GILTI in future years or recognizing such taxes as a current-period expense when incurred. During the fiscal years ended June 30, 2025 and 2024, we elected to treat the tax effect of GILTI as a current-period expense when incurred. Unrecognized Tax Benefits The following table summarizes our liability for uncertain tax positions for the fiscal year ended June 30, 2025:
Schedule of uncertain tax position |  |  |  |
|  | Year Ended |
|  | June 30, 2025 |
|  | (In thousands) |
Balance as of June 30, 2024 |  | $ | 4,289 |
Change in balances related to uncertain tax positions |  |  | (1,211 | )
Balance as of June 30, 2025 |  | $ | 3,078 |
At June 30, 2025, we had $3,078,000 of gross unrecognized tax benefits which was recorded as a reduction to deferred tax assets, and a corresponding reduction in our valuation allowance of $3,078,000. The balance decreased from the prior year due to the expiration of certain federal research and development tax credit carryforwards as well as the reversal of liabilities in connection with the dissolution of one of our foreign subsidiaries by a gross amount of $1,280,000. To the extent such portion of unrecognized tax benefits is recognized at a time such valuation allowance no longer exists, the recognition would reduce the effective tax rate. Our continuing practice is to recognize interest and penalties related to income tax matters in income tax expense. During the fiscal years ended June 30, 2025 and 2024, we recorded an immaterial expense for interest and penalties related to income tax matters in the provision for income taxes. At June 30, 2025, we had approximately $39,000 of accrued interest and penalties related to uncertain tax positions. At June 30, 2025, our fiscal years ended June 30, 2022 through 2025 remain open to examination by the federal taxing jurisdiction and our fiscal years ended June 30, 2021 through 2025 remain open to examination by the state taxing jurisdictions. However, we have NOLs beginning in the fiscal year ended June 30, 2005 which would cause the statute of limitations to remain open for the year in which the NOL was incurred. Our fiscal years ended June 30, 2017 through 2025 remain open to examination by foreign taxing authorities. We currently do not anticipate that the amount of unrecognized tax benefits as of June 30, 2025 will significantly increase or decrease within the next 12 months. New Tax Legislation In July 2025, the U.S. government enacted comprehensive legislation commonly referred to as the One Big Beautiful Bill Act of 2025 (the “OBBB Act”). The OBBB Act, which includes a broad range of tax reform provisions, including extending and modifying certain key Tax Cuts and Jobs Act provisions (both domestic and international). It includes reinstating the option to claim 100% accelerated deprecations deductions on qualified property and immediate expensing of domestic research and development costs. Income tax accounting guidance requires the effects of tax law changes to be recognized in the period of enactment. Since the legislation was signed into law after June 30, 2025, it had no impact on our operating results for the fiscal year ended June 30, 2025. We are currently assessing the impact on our financial statements in future periods.
