$0.8 million for the three months ended September 30, 2020, compared to the three months ended September 30, 2019. The decrease was primarily due to a decrease of $0.4 million in engine rents resulting from the Companys

Income Taxes
In the three months ended
September 30, 2020, our effective tax rate was (0.2)%, compared to (0.6)% for the three months ended September 30, 2019. Our tax rate can vary depending on changes in tax laws, adoption of accounting standards, the amount of income we earn
in each state and the state tax rate applicable to such income, as well as any valuation allowance required on our federal and state net operating losses.
We recorded an income tax benefit of $(0.01) million and an income tax provision of $0.1 million for the three months ended
September 30, 2020 and September 30, 2019, respectively.
The income tax benefit for the three months ended September 30,
2020 resulted in an effective tax rate of (0.2)%, which differed from the U.S. federal statutory rate of 21%, primarily due to the impact of state taxes, the partial reversal of valuation allowances on federal and state deferred tax assets, and
permanent differences between financial statement and taxable income.
The income tax provision for the three months ended
September 30, 2019 resulted in an effective tax rate of (0.6)%, which differed from the U.S. federal statutory rate of 21%, primarily due to the impact of state taxes, the establishment of valuation allowances on federal and state deferred tax
assets, and permanent differences between financial statement and taxable income.
We continue to maintain a valuation allowance on a
portion of our federal and state deferred tax assets for the three months ended September 30, 2020 and September 30, 2019.
