Accordingly, the accounting for certain income tax effects of the Act is provisional. We believe that we have a reasonable basis for our estimates.
Our effective income tax rate for the three and six months ended March 31, 2018 was 24.1% and 24.5%, respectively, compared to our effective income tax rate for the three and six months ended March 31, 2017 of 33.6% and 35.1%, respectively. The net effect of our toll charge and reduction of deferred tax liabilities reduced the effective income tax rate by approximately 1.5% and 1.4% for the three and six months ended March 31, 2018, respectively.
During the six months ended March 31, 2018 and 2017, we made income tax payments of $28.5 million and $38.8 million, respectively.
