Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES C.H. Robinson Worldwide, Inc. and its 80 percent (or more) owned U.S. subsidiaries file a consolidated federal 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 2010. During the first quarter of 2017, we adopted ASU 2016-09, Compensation - Stock Compensation (Topic 718). This adoption resulted in a decrease in our provision for income taxes for the three and nine months ended September 30, 2017 of $1.3 million and $11.9 million, respectively. We have asserted that we will indefinitely reinvest earnings of foreign subsidiaries to support expansion of our international business. If we repatriated all foreign earnings, the estimated effect on income taxes payable would be an increase of approximately $29.0 million as of September 30, 2017. Our effective tax rate for the three months ended September 30, 2017 and 2016 was 35.2 percent and 36.7 percent, respectively, and our effective tax rate for the nine months ended September 30, 2017 and 2016 was 34.2 percent and 37.1 percent, respectively. The effective income tax rate for the three months ended September 30, 2017 was higher than the statutory federal income tax rate due to state income taxes, net of federal benefit. The effective income tax rate for the nine months ended September 30, 2017 was lower than the statutory federal income tax rate due to the adoption of ASU 2016-09.
