Provision for Income Taxes
The Company files a consolidated United States income tax return and income tax returns in various states. Management evaluated the Company's tax positions at December 31, 2018, based on appropriate provisions of applicable enacted tax laws and regulations, and believes that they are supportable based on their specific technical merits and the facts and circumstances of the respective transactions.
On December 22, 2017, the United States government enacted comprehensive tax legislation known as the Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act included broad and complex changes to the United States tax code, including a reduction in the United States federal corporate income tax rate from 35.0% to 21.0% effective January 1, 2018. Accordingly, the United States statutory income tax rate applicable to the Company was 21.0% and 35.0% during the three months ended December 31, 2018 and December 31, 2017, respectively. During the three months ended December 31, 2017, the Company recorded a provisional discrete tax benefit of $3.5 million related to the Tax Act, primarily related to an adjustment of its United States deferred tax liabilities by the same amount, reflecting the reduction in the United States federal corporate tax rate. This net reduction in deferred tax liabilities also included the estimated impact on the Company's net state deferred tax assets. The Company completed its accounting for the income tax effects of the Tax Act during the fourth quarter of its fiscal year ended September 30, 2018.
The Company's effective tax rate for the three months ended December 31, 2018 and 2017 was 24.3% and (7.8)%, respectively. The lower effective tax rate for the three months ended December 31, 2017 compared to the three months ended December 31, 2018 was primarily due to the benefit of the tax credit recorded during the three months ended December 31, 2017 related to the enactment of the Tax Act.
