Income Taxes

4.    Income Taxes

U.S. Cellular is included in a consolidated federal income tax return and in certain state income tax returns with other members of the TDS consolidated group.  For financial statement purposes, U.S. Cellular and its subsidiaries compute their income tax expense as if they comprised a separate affiliated group and were not included in the TDS consolidated group.

U.S. Cellular’s overall effective tax rate on Income (loss) before income taxes for the three and six months ended June 30, 2015 was 39.6% and 39.5%, respectively, and for the three and six months ended June 30, 2014 was 34.8% and 190.4%, respectively.

The unusually high effective tax rate for the six months ended June 30, 2014 resulted from the relatively low amount of Income (loss) before income taxes in that period, which magnified the effective rate impact of discrete tax expense items.
