Income Tax Disclosure [Abstract]
Income Taxes	8. Income Taxes Fluctuations in our provision for/(benefit from) income taxes as a percentage of pretax earnings (“effective tax rate”) are generally due to changes in international and U.S. state effective tax rates resulting from our business mix and discrete items. Opioid Settlement Framework In connection with the $5.63 billion pre-tax charge for the opioid litigation, during the nine months ended March 31, 2020 we recorded a tax benefit of $487 million, which is net of unrecognized tax benefits of $468 million, reflecting our current assessment of the estimated future deductibility of the amount that may be paid. We have made reasonable estimates and recorded amounts based on management's judgment and our current understanding of the Tax Act; however, these estimates require significant judgment since the definitive settlement terms and documentation, including provisions related to deductibility, under the Settlement Framework have not been negotiated and the U.S. tax law governing deductibility was changed by the U.S. Tax Cuts and Jobs Act ("Tax Act"). Further, it is possible that the tax authorities could challenge our interpretation of the Tax Act or the estimates and assumptions used to assess the future deductibility of these benefits. The actual amount of the tax benefit related to uncertain tax positions may differ materially from these estimates. See Note 7 for more information regarding these matters. Effective Tax Rate During the three months ended March 31, 2020 and 2019, the effective tax rate was 26.8 percent and 20.0 percent, respectively. The increase in the effective tax rate from the prior period was primarily due to changes in discrete tax items and jurisdictional mix. During the nine months ended March 31, 2020 and 2019, the effective tax rate was 5.2 percent and 22.6 percent, respectively. The decrease in the effective tax rate from fiscal 2019 to fiscal 2020 was primarily due to the net tax effects of the Settlement Framework. Unrecognized Tax Benefits At March 31, 2020 and June 30, 2019, we had $919 million and $456 million of unrecognized tax benefits, respectively. The March 31, 2020 and June 30, 2019 balances include $772 million and $303 million of unrecognized tax benefits, respectively, that if recognized, would have an impact on the effective tax rate. At March 31, 2020 and June 30, 2019, we had $137 million and $122 million, respectively, accrued for the payment of interest and penalties related to unrecognized tax benefits, which we recognize in the provision for/(benefit from) income taxes in the condensed consolidated statements of earnings/(loss). These balances are gross amounts before any tax benefits and are included in deferred income taxes and other liabilities in the condensed consolidated balance sheets. It is reasonably possible that there could be a change in the amount of unrecognized tax benefits within the next 12 months due to activities of the U.S. Internal Revenue Service ("IRS") or other taxing authorities, possible settlement of IRS and other audit issues, reassessment of existing unrecognized tax benefits or the expiration of statutes of limitations. We estimate that the range of the possible change in unrecognized tax benefits within the next 12 months is between zero and a net decrease of up to $350 million, exclusive of penalties and interest. Other Tax Matters We file income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions and various foreign jurisdictions. With few exceptions, we are subject to audit by taxing authorities for fiscal years 2008 through the current fiscal year. Tax laws are complex and subject to varying interpretations. Tax authorities have challenged some of our tax positions, including IRS challenges to our international transfer pricing for the periods from 2008 to 2014, and it is possible that they will challenge others. These challenges may adversely affect our effective tax rate or tax payments. We are a party to a tax matters agreement with CareFusion Corporation ("CareFusion"), a subsidiary of Becton, Dickinson and Company. Under the tax matters agreement, CareFusion is obligated to indemnify us for certain tax exposures and transaction taxes prior to our fiscal 2010 spin-off of CareFusion. The indemnification receivable was $173 million and $165 million at March 31, 2020 and June 30, 2019, respectively, and is included in other assets in the condensed consolidated balance sheets. As a result of the acquisition of the Patient Recovery Business, Medtronic plc is obligated to indemnify us for certain tax exposures and transaction taxes related to periods prior to the acquisition under the purchase agreement. The indemnification receivable was $18 million and $22 million at March 31, 2020 and June 30, 2019, respectively, and is included in other assets in the condensed consolidated balance sheet. Future adjustments to the financial statements may be necessary as final tax regulations related to U.S. Tax Reform are issued. We will assess any impact as additional guidance is issued.
