The effective tax rates were 23.3 percent and 16.5 percent for the three months ended June 30, 2026 and 2025, respectively. The higher tax rate for the three months ended June 30, 2026 was primarily driven by the unfavorable tax impact of nondeductible acquired IPR&D charges and, to a lesser extent, a mix of earnings in higher tax jurisdictions and the unfavorable tax impact of asset impairment, restructuring, and other special charges.
The effective tax rates were 19.9 percent and 17.7 percent for the six months ended June 30, 2026 and 2025, respectively. The higher tax rate for the six months ended June 30, 2026 was primarily driven by a mix of earnings in higher tax jurisdictions and the unfavorable tax impact of asset impairment, restructuring, and other special charges. The effective tax rates in both periods were unfavorably impacted by nondeductible acquired IPR&D charges.
At June 30, 2026 and December 31, 2025, prepaid expenses included prepaid taxes of $13.6 billion and $12.9 billion, respectively.
The U.S. examination of tax years 2019-2021 remains ongoing. For tax years 2016-2018, we are pursuing competent authority assistance through the Mutual Agreement Procedure (MAP) process for the pricing of certain intercompany transactions. The resolution of both audit periods will likely extend beyond the next 12 months.
