NOTE 5. INCOME TAXES
On July 4, 2025, the One Big Beautiful Bill Act (The Act) was signed into law, enacting significant changes to U.S. federal income tax rules affecting corporations, such as the ability to immediately deduct domestic research and development costs, restoration of elective 100 percent bonus depreciation for qualified property and changes to the international tax provisions. Implementation of The Act resulted in an increase to tax expense of $36 million in the third quarter of 2025, primarily due to a reduction in the foreign income deduction and changes to the research and development tax credit.
Our effective tax rates for the three and nine months ended September 30, 2025, were 32.7 percent and 26.3 percent, respectively. Our effective tax rates for the three and nine months ended September 30, 2024, were 19.2 percent and 14.6 percent, respectively.
The three months ended September 30, 2025, contained net unfavorable discrete tax items of $4 million primarily due to $32 million of unfavorable return to provision adjustments and net $1 million of other unfavorable tax items, partially offset by $25 million of favorable adjustments for uncertain tax positions and $4 million of favorable adjustments for share-based compensation.

The three months ended September 30, 2024, contained net favorable discrete tax items of $36 million, primarily due to $20 million of favorable adjustments from tax return amendments, $15 million of favorable return to provision adjustments and $2 million of favorable share-based compensation tax benefits, partially offset by $1 million of other unfavorable adjustments.
The nine months ended September 30, 2024, contained net favorable discrete tax items primarily due to the $1.3 billion non-taxable gain on the Atmus split-off. Other discrete tax items were net favorable by $66 million, primarily due to $21 million of favorable adjustments related to audit settlements, $20 million of favorable adjustments from tax return amendments, $18 million of favorable return to provision adjustments and $17 million of favorable share-based compensation tax benefits, partially offset by $7 million of unfavorable adjustments for uncertain tax positions and $3 million of other unfavorable adjustments.
