Table of Contents Notes to Consolidated Financial Statements — (Continued) Becton, Dickinson and Company Note 17 — Income Taxes Provision for Income Taxes Unrecognized Tax Benefits The provision (benefit) for income taxes the years ended September 30 consisted of: The components of  Income Before Income Taxes  for the years ended September 30 consisted of: U.S. tax legislation, commonly referred to as the Tax Cuts and Jobs Act (the "Act"), was enacted on December 22, 2017. The Act reduced the U.S. federal corporate tax rate from 35% to 21%, required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, and created new taxes on certain foreign-sourced earnings. The Act subjects a U.S. shareholder to tax on global intangible low-taxed income ("GILTI") earned by certain foreign subsidiaries. The Company has elected to account for its GILTI tax due as a period expense in the year the tax is incurred. During fiscal year 2019, the Company finalized its accounting for the income tax effects of the Act, and all adjustments related to finalization of its calculations were included as a component of  Income tax provision (benefit)  in fiscal year 2019. The Company recognized additional tax benefit of $50 million and additional tax cost of $640 million in 2019 and 2018, respectively, as a result of this legislation. These amounts are reflected in the Company's consolidated statements of income within  Income tax provision (benefit) . During fiscal year 2019, the Company also changed its assertion with respect to historical unremitted foreign earnings, which resulted in a total tax benefit of $138 million, of which $67 million is related to the tax legislation benefit previously recorded, and is included as a component of  Income tax provision (benefit)  in fiscal 2019. The Company asserts indefinite reinvestment for all historical unremitted foreign earnings as of September 30, 2020. The table below summarizes the gross amounts of unrecognized tax benefits without regard to reduction in tax liabilities or additions to deferred tax assets and liabilities if such unrecognized tax benefits were settled. The Company believes it is reasonably possible that the amount of unrecognized benefits will change due to one or more of the following events in the next twelve months: expiring statutes, audit activity, tax payments, other activity, or final decisions in matters that are the subject of controversy in various taxing jurisdictions in which we operate. 95 (Millions of dollars) 2020 2019 2018 Current: Federal $ (50) $ 235  $ 665  State and local, including Puerto Rico 47  41  73  Foreign 400  300  387  $ 397  $ 576  $ 1,124  Deferred: Domestic $ (184) $ (577) $ (201) Foreign (101) (56) (61) (286) (633) (262) Income tax provision (benefit) $ 111  $ (57) $ 862  (Millions of dollars) 2020 2019 2018 Domestic, including Puerto Rico $ (489) $ 799  $ (135) Foreign 1,474  377  1,308  Income Before Income Taxes $ 985  $ 1,176  $ 1,173
