--- | ---
Sep. 30, 2025
Income Tax Disclosure [Text Block] | INCOME TAXES The effective tax rate for the three and nine months ended September 30, 2025 was 16.8 percent and 21.5 percent, respectively, and 18.0 percent and 23.1 percent for the three and nine months ended September 30, 2024, respectively. During the three and nine months ended September 30, 2025, the company recognized $2 million and $37 million, respectively, of net tax benefits for income taxes on continuing operations associated with changes in deferred taxes and accruals for certain prior year tax positions in various jurisdictions as well as from stock-based compensation. During the nine months ended September 30, 2025, the company recognized a $55 million deferred tax benefit associated with a change in a legal entity’s U.S. tax characterization. During the three and nine months ended September 30, 2024, the company recognized $10 million and $25 million, respectively, of net tax benefits for income taxes on continuing operations associated with changes in deferred taxes and accruals for certain prior year tax positions in various jurisdictions as well as from stock-based compensation. The company routinely uses foreign currency exchange contracts to offset its net exposures, by currency, related to the foreign currency-denominated monetary assets and liabilities. The objective of the program, which resides in the U.S., is to maintain an approximately balanced position in foreign currencies in order to minimize, on an after-tax basis, the effects of exchange rate changes on net monetary asset positions, which can drive material impacts on the company's effective tax rate. For further discussion of pre-tax and after-tax impacts of the company's foreign currency hedging program and net monetary asset programs, refer to Note 5 - Supplementary Information, to the interim Consolidated Financial Statements. On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was signed into law, enacting changes in a wide array of policy areas, including federal tax law. The impacts of OBBBA are included in the financial statements for the three and nine months ended September 30, 2025, including the reinstatement of expensing of domestic research and development expenditures.

Income Tax Disclosure [Text Block] | INCOME TAXES Refer to page 15 of the Corteva, Inc. interim Consolidated Financial Statements for discussion of tax items that do not differ between Corteva, Inc. and EIDP.
