INCOME TAXES
C.H. Robinson Worldwide, Inc. and its 80 percent (or more) owned U.S. subsidiaries file a consolidated federal income tax return. We file unitary or separate state returns based on state filing requirements. With few exceptions, we are no longer subject to audits of U.S. federal, state and local, or non-U.S. income tax returns before 2009.
Our effective tax rate for the three months ended March 31, 2015 and 2014 was 38.2 percent and 38.2 percent, respectively. The effective income tax rate for both periods is greater than the statutory federal income tax rate due to state income taxes, net of federal benefit.
