Note 9 - Income Taxes
We recorded income tax benefit of $136 thousand and income tax expense of $1.1 million for the three months ended March 31, 2022 and 2021, respectively. Our effective tax rate was 20.0% and 92.7% for the three months ended March 31, 2022 and 2021, respectively. Our effective tax rates differed from the U.S. statutory corporate tax rate of 21% primarily because of our reduced operations while also recognizing revenues from the expiration of student contracts.
The Company assessed the weight of all available positive and negative evidence and determined it was more likely than not that future earnings will be sufficient to realize the associated deferred tax assets. As of March 31, 2022 and December 31, 2021, we retained a valuation allowance of $ 3.5 million and $3.5 million, respectively, for a certain number of our international subsidiaries.
During the three months ended March 31, 2022 and 2021, there were no material changes in uncertain tax positions. We do not expect any significant changes to unrecognized tax benefits in this and next year. We estimate $0.3 million and $0.3 million of the unrecognized tax benefits, which if recognized, would impact the effective tax rate at March 31, 2022 and December 31, 2021, respectively.
We record interest and penalties related to unrecognized tax benefits within the provision for income taxes. We believe that no current tax positions that have resulted in unrecognized tax benefits will significantly increase or decrease within one year. We file income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions.
We are not currently under examination in any jurisdiction. In the event of any future tax assessments, we have elected to record the income taxes and any related interest and penalties as income tax expense on our consolidated statements of operations and comprehensive income.
Our federal income tax returns for the years subsequent to 2019 are subject to examination by the Internal Revenue Service. Our state tax returns for all years after 2019 or 2018, depending on each state’s jurisdiction, are subject to examination. In addition, our Canadian tax returns and United Kingdom tax returns for all years after 2015 are subject to examination.
The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
