Abbott is contesting IRS Statutory Notices of Deficiency totaling $1.052 billion for the 2017–2020 federal tax years, primarily involving proposed reallocations of income between U.S. entities and foreign affiliates. Abbott also faces a $413 million Malaysian tax assessment for 2023 related to property capital gains on an intercompany affiliate sale; the Penang High Court upheld the assessment in October 2025, and Abbott appealed to the Malaysian Court of Appeals. Abbott remains in active discussions with the IRS and says it will defend its positions through discussions or litigation.
