Income Taxes	9. Income Taxes At the end of each interim period we are required to estimate our annual effective tax rate for the fiscal year, and to use that rate to provide for income taxes for the current year-to-date reporting period. Our 2016 estimated annual effective tax rate is driven by our blended federal and state statutory rate of 37.3%, which is partially offset by estimated benefits of 3.3% from additional deductions for tax related to domestic production activities and estimated energy credits, resulting in an estimated annual effective tax rate of 34.0%. For the three months ended June 30, 2016 and 2015, we recorded income tax expense of $6.0 million and $4.6 million, respectively.

Our income tax expense for the three months ended June 30, 2016 is based on our estimated annual effective tax rate, a discrete item related to the vesting of restricted stock awards which increased income tax expense by $0.1 million and energy credits certified during the three months ended June 30, 2016 related to homes delivered in prior years which decreased our expense by $0.6 million.

9. Income Taxes

At the end of each interim period we are required to estimate our annual effective tax rate for the fiscal year, and to use that rate to provide for income taxes for the current year-to-date reporting period. Our 2016 estimated annual effective tax rate is driven by our blended federal and state statutory rate of 37.3%, which is partially offset by estimated benefits of 3.3% from additional deductions for tax related to domestic production activities and estimated energy credits, resulting in an estimated annual effective tax rate of 34.0%.

For the three months ended June 30, 2016 and 2015, we recorded income tax expense of $6.0 million and $4.6 million, respectively. For the six months ended June 30, 2016 and 2015, we recorded income tax expense of $10.4 million and $7.8 million, respectively. Our income tax expense for the three months ended June 30, 2016 is based on our estimated annual effective tax rate, a discrete item related to the vesting of restricted stock awards which increased income tax expense by $0.1 million and energy credits certified during the three months ended June 30, 2016 related to homes delivered in prior years which decreased our expense by $0.6 million.
