Income Tax Disclosure [Abstract] |
Income Tax Disclosure [Text Block] | INCOME TAXES On December 22, 2017, the Tax Cuts and Jobs Act (“The Act”) was enacted. The Act reduces the U.S. federal corporate income tax rate from 35 percent to 21 percent, requires companies to pay a one-time transition tax (“transition tax”) on earnings of foreign subsidiaries that were previously tax deferred, creates new provisions related to foreign sourced earnings, eliminates the domestic manufacturing deduction and moves towards a territorial system. At June 30, 2018, the company had not completed its accounting for the tax effects of The Act; however, as described below, the company has made reasonable estimates of the effects on its existing deferred tax balances and the one-time transition tax. In accordance with Staff Accounting Bulletin 118 ("SAB 118"), during the measurement period, income tax effects of the Act may be refined upon obtaining, preparing, or analyzing additional information, and such changes could be material. During the measurement period, provisional amounts may also be adjusted for the effects, if any, of interpretive guidance issued by U.S. regulatory and standard-setting bodies.
• | As a result of The Act, the company remeasured its U.S. federal deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21 percent. However, the company is still analyzing certain aspects of The Act and refining its calculations. In the three and six months ended June 30, 2018, charges of $7 million and $55 million, respectively, were recorded to provision for income taxes on continuing operations in the company's interim Consolidated Income Statements to adjust the provisional amount related to the remeasurement of the company's deferred tax balance, resulting in a benefit of $(2,661) million since the enactment of The Act.
• | The Act requires a mandatory deemed repatriation of post-1986 undistributed foreign earnings and profits (“E&P”), which results in a one-time transition tax. The company has not yet completed its calculation of the total post-1986 foreign E&P for its foreign subsidiaries as E&P will not be finalized until the Federal income tax return is filed. The company has not recorded a change to the $715 million provisional charge recorded during the fourth quarter 2017 with respect to the one-time transition tax.
• | In the six months ended June 30, 2018, the company recognized a charge of $16 million to provision for income taxes on continuing operations in the company's interim Consolidated Income Statements as a result of an indirect impact of the Act related to certain inventory.
• | For tax years beginning after December 31, 2017, The Act introduces new provisions for U.S. taxation of certain global intangible low-taxed income ("GILTI"). The company is evaluating the policy election on whether the additional liability will be recorded in the period in which it is incurred or recognized for the basis differences that would be expected to reverse in future years.
DuPont and its subsidiaries are included in DowDuPont's consolidated federal income tax group and consolidated tax return. Generally, the consolidated tax liability of the DowDuPont U.S. tax group for each year will be apportioned among the members of the consolidated group based on each member’s separate taxable income. DuPont and Dow intend that to the extent Federal and/or State corporate income tax liabilities are reduced through the utilization of tax attributes of the other, settlement of any receivable and payable generated from the use of the other party’s sub-group attributes will be in accordance with a tax sharing agreement and/or tax matters agreement. Each year the company files hundreds of tax returns in the various national, state and local income taxing jurisdictions in which it operates. These tax returns are subject to examination and possible challenge by the tax authorities. Positions challenged by the tax authorities may be settled or appealed by the company. As a result, there is an uncertainty in income taxes recognized in the company's financial statements in accordance with accounting for income taxes and accounting for uncertainty in income taxes. The ultimate resolution of such uncertainties is not expected to have a material impact on the company's results of operations. During the three months ended June 30, 2017, the company recognized tax expense of $29 million associated with the elimination of the U.S. domestic manufacturing deduction recorded in 2016 due to taxable income limitations triggered by the company's decision to deduct the second quarter 2017 principal U.S. pension plan contribution on its 2016 consolidated U.S. tax return. Additionally, during the six months ended June 30, 2017, the company recognized a tax benefit of $57 million, as well as a $50 million pre-tax benefit on associated accrued interest reversals, related to a reduction in the company's unrecognized tax benefits due to the closure of various tax statutes of limitations. Income from continuing operations during the six months ended June 30, 2017 includes a tax benefit of $53 million and a pre-tax benefit of $47 million for accrued interest reversals (recorded in sundry income (expense) - net). Income from discontinued operations during the six months ended June 30, 2017 includes a tax benefit of $4 million and a pre-tax benefit of $3 million for the accrued interest reversal.
