14. | Income Tax
Income tax expense for the years ended December 31, 2023 and 2022, consisted of:
|  | Year Ended December 31, |
(in thousands) |  | 2023 |  |  | 2022 |
Current income tax expense: |  |  |  |  |  |  |  |
Federal and state |  | $ | 570 |  |  | $ | 641 |
Foreign |  |  | 61 |  |  |  | 194 |
|  |  | 631 |  |  |  | 835 |
Deferred income tax expense (benefit): |  |  |  |  |  |  |  |
Federal and state |  |  | 132 |  |  |  | (468 | )

|  |  | 228 |  |  |  | (498 | )
Total income tax expense |  | $ | 859 |  |  | $ | 337 |
The effective tax rate for the year ended December 31, 2023 was (33.5)% as compared with (3.7)% for the same period in 2022. The difference between the Company’s effective tax rate year over year was primarily attributable to changes in the mix of pre-tax income and losses at individual subsidiaries, and the impact of changes in uncertain tax positions. Income tax expense for the years ended December 31, 2023 and 2022, differed from the amount computed by applying the U.S. federal income tax rate of 21% to pre-tax loss as a result of the following:
|  | Year Ended December 31, |

At December 31, 2023, the Company had state net operating loss carryforwards of $6.3 million, which expire between 2024 and 2043. The Company had net operating loss carryforwards of $7.8 million in certain foreign jurisdictions which may be carried forward indefinitely, partially offset by valuation allowances. The Company had $7.8 million of research and development tax credit carryforwards which begin to expire in 2024, and are partially offset by a reserve of $0.8 million for uncertain tax positions. The Company had a total of $2.7 million of state investment tax credit carryforwards, research and development tax credit carryforwards, and enterprise zone credit carryforwards, which begin to expire in 2024. In addition, the Company had a total of $0.4 million international R&D credits which begin to expire in 2037. The Internal Revenue Code (“IRC”) limits the amounts of net operating loss carryforwards or credits that a company may use in any one year in the event of a change in ownership under IRC Sections 382 or 383. As a result of various acquisitions in prior years, certain losses and credit carryforwards are subject to these limitations. As of December 31, 2023 and 2022, the Company maintained a total valuation allowance of $15.2 million and $14.5 million, respectively, which relates to foreign, federal, and state deferred tax assets in both years. The valuation allowance is based on estimates of taxable income in each of the jurisdictions in which the Company operates and the period over which deferred tax assets will be recoverable. The net change in the total valuation allowance for the years ended December 31, 2023 and 2022, was an increase of $0.7 million and a decrease of $0.2 million, respectively. During the year ended December 31, 2023, the Company increased the valuation allowance related to the estimate of realizability of German deferred tax assets and deferred tax assets related to the Employee Retention Credit, offset by the utilization and expiration of certain U.S. federal and state net operating losses and the expiration of certain U.S. credits. As of December 31, 2023 and 2022, cash and cash equivalents held by the Company’s foreign subsidiaries were $2.1 million and $2.6 million, respectively. As of December 31, 2023, the Company has determined the potential income tax and withholding liability related to available cash balances at foreign subsidiaries to be immaterial. A summary of activity of unrecognized tax benefits is as follows:
|  | (in thousands) |
Balance at December 31, 2021 |  | $ | 1,332 |
Additions based on tax positions of prior years |  |  | 534 |
Decreases based on tax positions of prior years |  |  | (34 | )
Additions based on tax positions of current year |  |  | 237 |
Other decreases, net |  |  | (86 | )
Balance at December 31, 2022 |  |  | 1,983 |
Additions based on tax positions of prior years |  |  | 13 |
Decreases based on tax positions of prior years |  |  | 57 |
Additions based on tax positions of current year |  |  | 245 |
Other decreases, net |  |  | (76 | )
Balance at December 31, 2023 |  | $ | 2,222 |
We expect the amount of unrecognized tax benefits to change within the next twelve months, including the release of reserves of approximately $0.4 million. Substantially all of the liability for uncertain tax benefits related to various federal, state and foreign income tax matters would benefit the Company's effective tax rate, if recognized. The Company classifies interest and penalties related to unrecognized tax benefits as a component of income tax expense, which has not been significant during the years ended December 31, 2023 and 2022, respectively. With a few exceptions, the Company is no longer subject to income tax examinations by tax authorities in foreign jurisdictions for the years before 2019. In the U.S., the Company’s net operating loss and tax credit carryforward amounts remain subject to federal and state examination for tax years starting in 2004 as a result of tax losses incurred in prior years. There are currently no pending federal or state tax examinations.
