Historically, we calculated our provision for income taxes during interim reporting periods by applying the estimated annual effective tax rate for the full fiscal year to pre-tax income or loss, excluding discrete items, for the reporting period. We determined that since small changes in estimated pre-tax income or loss would result in significant changes in the estimated annual effective tax rate, the historical method would not provide a reliable estimate of income taxes for the three and nine months ended September 30, 2023 and 2022, and therefore, we used a discrete effective tax rate method to calculate income taxes for each of these periods. We will continue to evaluate income tax estimates under the historical method in subsequent quarters and employ a discrete effective tax rate method if warranted.

Discrete income tax benefit for the three months ended September 30, 2023 was $2.0 million and was primarily attributable to the resolution of prior period tax matters, partially offset by changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years. Discrete income tax benefit of $39.5 million for the nine months ended September 30, 2023 was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years and the resolution of other prior period tax matters. Excluding the aforementioned discrete tax items, income tax expense for the three and nine months ended September 30, 2023 was $12.7 million and $47.1 million, respectively.
A substantial portion of our deferred tax assets are subject to a valuation allowance. During the three months ended September 30, 2023, we recognized a $6.2 million deferred tax benefit from the reduction of valuation allowances on deferred tax assets for a change in estimated future taxable income in certain operating jurisdictions. We intend to continue maintaining a valuation allowance on a substantial portion of our deferred tax assets until there is sufficient evidence to support a reversal of such allowances. However, given the current operating environment and our anticipated future earnings, we believe there is a reasonable possibility that sufficient positive evidence may become available to allow us to reach a conclusion that a portion of the valuation allowance on deferred tax assets will no longer be needed. A reduction in our valuation allowance would result in the recognition of a deferred tax benefit during the period in which the reduction is recognized. The timing and amount of future valuation allowance reductions are subject to future levels of contracting and profitability achieved.

Discrete income tax expense for the three months ended September 30, 2022 was $1.4 million and was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years, partially offset by discrete tax benefits attributable to the resolution of other prior period tax matters. Discrete income tax benefit for the nine months ended September 30, 2022 was $6.9 million and was primarily attributable to changes in liabilities for unrecognized tax benefits associated with tax positions taken in prior years and resolution of other prior period tax matters, partially offset by discrete tax expense attributable to income associated with a contract termination. Excluding the aforementioned discrete tax items, income tax expense for the three and nine months ended September 30, 2022 was $12.4 million and $40.2 million, respectively.
