Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We are subject to both direct and indirect taxation in the U.S. and various states and foreign jurisdictions. We are under examination by certain tax authorities for the 2003 to 2013 tax years. We believe that adequate amounts have been reserved for any adjustments that may ultimately result from these or other examinations. The material jurisdictions where we are subject to potential examination by tax authorities for tax years after 2002 include, among others, the U.S. (Federal and California), Germany, Korea, Israel, Switzerland, United Kingdom and Canada. Although the timing of the resolution and/or closure of audits is highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits could significantly change in the next 12 months. However, given the number of years remaining subject to examination and the number of matters being examined, we are unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits. During the fourth quarter of 2016, we began the process of realigning our legal structure, subsequent to the distribution of PayPal Holdings, Inc., to better reflect how we manage and operate our platforms. We consider many factors in effecting this realignment, including foreign exchange exposures, long-term cash flows and cash needs of our platforms, capital allocation considerations and the associated tax effects. As a result of the initial stages of this realignment and the associated tax agreements, in 2016 we achieved a substantial step-up in the tax basis of the intangible assets in our foreign eBay platforms. In the first quarter of 2017, we achieved a step-up in the tax basis of the intangible assets in our foreign Classifieds platforms and recognized a tax benefit of $695 million. As a result of the realignment, we no longer benefit from tax rulings previously concluded in several different jurisdictions. Without the benefit of the rulings, the noncash tax impacts of the realignment in our foreign eBay and Classifieds platforms have increased our income tax rate in certain foreign jurisdictions, most significantly Switzerland. While we experienced a higher tax rate, the realignment allows us to achieve certain cash tax benefits due to the step-up in tax basis achieved in certain foreign jurisdictions. These cash tax benefits will remain consistent, subject to the performance of our foreign platforms. The realignment is expected to extend into 2018 and primarily impact our international entities. On July 27, 2015, in Altera Corp. v. Commissioner, the U.S. Tax Court issued an opinion invalidating the regulations relating to the treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. A final decision was issued by the Tax Court in December 2015. The IRS is appealing the decision and filed its arguments opposing the Tax Court decision in June 2016. Due to the uncertainty surrounding the status of the current regulations, questions related to the scope of potential benefits or obligations, and the risk of the Tax Court’s decision being overturned upon appeal, we have not recorded any benefit or expense as of March 31, 2017.
