Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our tax provision for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, we update the estimated annual effective tax rate and make a year-to-date adjustment to the provision. The estimated annual effective tax rate is subject to significant volatility due to several factors, including our ability to accurately predict the proportion of our income (loss) before provision for income taxes in multiple jurisdictions, the U.S. tax benefits from foreign derived intangible income, the effects of acquisitions, and the integration of those acquisitions. Our gross unrecognized tax benefits were $8.06 billion and $7.86 billion on June 30, 2020 and December 31, 2019, respectively. If the gross unrecognized tax benefits as of June 30, 2020 were realized in a subsequent period, this would result in a tax benefit of $4.17 billion within our provision of income taxes at such time. The amount of interest and penalties accrued was $774 million and $747 million as of June 30, 2020 and December 31, 2019, respectively. We expect to continue to accrue unrecognized tax benefits for certain recurring tax positions. On July 27, 2015, the United States Tax Court issued a decision (Tax Court Decision) in Altera Corp. v. Commissioner, which concluded that related parties in a cost sharing arrangement are not required to share expenses related to share-based compensation. The Tax Court Decision was appealed by the Commissioner to the Ninth Circuit Court of Appeals (Ninth Circuit). On June 7, 2019, the Ninth Circuit issued an opinion (Altera Ninth Circuit Opinion) that reversed the Tax Court Decision. Based on the Altera Ninth Circuit Opinion, we recorded a cumulative income tax expense of $1.11 billion in the second quarter of 2019. On July 22, 2019, the taxpayer requested a rehearing before the full Ninth Circuit and the request was denied on November 12, 2019. The taxpayer requested a hearing before the Supreme Court of the United States and the request was denied on June 22, 2020. Since we started to accrue income tax for stock-based compensation cost-sharing in the second quarter of 2019, the denial of the request by the Supreme Court did not have a material impact to our financial results in the second quarter of 2020. We are subject to taxation in the United States and various other state and foreign jurisdictions. The material jurisdictions in which we are subject to potential examination include the United States and Ireland. We are under examination by the Internal Revenue Service (IRS) for our 2014 through 2016 tax years and by the Ireland tax authorities for our 2012 through 2018 tax years. Our 2017 and subsequent tax years remain open to examination by the IRS. Our 2019 and subsequent tax years remain open to examination in Ireland. In July 2016, we received a Statutory Notice of Deficiency (Notice) from the IRS related to transfer pricing with our foreign subsidiaries in conjunction with the examination of the 2010 tax year. While the Notice applies only to the 2010 tax year, the IRS stated that it will also apply its position for tax years subsequent to 2010. We do not agree with the position of the IRS and have filed a petition in the Tax Court challenging the Notice. On January 15, 2020, the IRS filed its Pretrial Memorandum in the case stating that it planned to assert at trial an adjustment that is higher than the adjustment stated in the Notice. The first session of the trial began in February 2020 and a second session is expected to continue in 2021. It is not clear how the IRS intends to apply the revised adjustment to future years. Based on the information provided, we believe that, if the IRS prevails in its updated position, this could result in an additional federal tax liability of an estimated, aggregate amount of up to approximately $9.0 billion in excess of the amounts in our originally filed U.S. return, plus interest and any penalties asserted. In March 2018, we received a second Notice from the IRS in conjunction with the examination of our 2011 through 2013 tax years. The IRS applied its position from the 2010 tax year to each of these years and also proposed new adjustments related to other transfer pricing with our foreign subsidiaries and certain tax credits that we claimed. If the IRS prevails in its position for these new adjustments, this could result in an additional federal tax liability of up to approximately $680 million in excess of the amounts in our originally filed U.S. returns, plus interest and any penalties asserted. We do not agree with the positions of the IRS in the second Notice and have filed a petition in the Tax Court challenging the second Notice. We have previously accrued an estimated unrecognized tax benefit consistent with the guidance in ASC 740, Income Taxes, that is lower than the potential additional federal tax liability from the positions taken by the IRS in the two Notices and its Pretrial Memorandum. In addition, if the IRS prevails in its positions related to transfer pricing with our foreign subsidiaries, the additional tax that we would owe would be partially offset by a reduction in the tax that we owe under the mandatory transition tax on accumulated foreign earnings from the 2017 Tax Cuts and Jobs Act (Tax Act). As of June 30, 2020, we have not resolved these matters and proceedings continue in the Tax Court. We believe that adequate amounts have been reserved in accordance with ASC 740 for any adjustments to the provision for income taxes or other tax items that may ultimately result from these examinations. The timing of the resolution, settlement, and closure of any audits is highly uncertain, and it is reasonably possible that the balance of gross unrecognized tax benefits could significantly change in the next 12 months. Given the number of years remaining that are subject to examination, we are unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits. If the taxing authorities prevail in the assessment of additional tax due, the assessed tax, interest, and penalties, if any, could have a material adverse impact on our financial position, results of operations, and cash flows.
