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 $39 million in 2025, primarily due to a reduction in the foreign income deduction and changes to the research and development tax credit.
During 2025, we responded to rapidly deteriorating conditions in our electrolyzer markets and overall hydrogen market in our Accelera segment by recording $458 million in charges related to inventory write-downs, asset impairments, severance and contract termination costs. These actions resulted in an increase in the effective tax rate of 2.6 percent in 2025. See NOTE 22, “ACCELERA ACTIONS,” for additional information.
Reconciliations of the statutory U.S. federal income tax expense and tax rate to the net expense and effective tax rate were as follows:

The year ended December 31, 2025 contained net favorable discrete tax items of $75 million, primarily due to $51 million of favorable adjustments for uncertain tax positions, $15 million of favorable adjustments for share-based compensation tax benefits, $7 million of favorable return to provision adjustments and $2 million of other favorable adjustments.

The year ended December 31, 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 $59 million, primarily due to $52 million of favorable return to provision adjustments, $22 million of favorable share-based compensation tax benefits, $21 million of favorable adjustments related to audit settlements and $20 million of favorable adjustments from tax return amendments, partially offset by $50 million of unfavorable adjustments related to Accelera strategic reorganization actions and net $6 million of other unfavorable adjustments. See NOTE 21, “ATMUS DIVESTITURE,” and NOTE 22, “ACCELERA ACTIONS,” for additional information.
The year ended December 31, 2023, contained unfavorable net discrete tax items of $397 million, primarily due to $398 million in the fourth quarter related to the $2.0 billion charge from the Settlement Agreements, $22 million of unfavorable adjustments for uncertain tax positions and $3 million of net unfavorable other discrete tax items, partially offset by $21 million of favorable return to provision adjustments and $5 million of favorable share-based compensation tax benefits. See NOTE 14, “COMMITMENTS AND CONTINGENCIES,” for additional information.
At December 31, 2025, certain non-U.S. earnings are considered indefinitely reinvested in operations outside the U.S. for which deferred taxes were not provided. Determination of the related deferred tax liability, if any, is not practicable because of the complexities associated with the hypothetical calculation.
Carryforward tax benefits and the tax effect of temporary differences between financial and tax reporting that give rise to net deferred tax assets (liabilities) were as follows:

Our 2025 U.S. carryforward benefits include $258 million of state credit and net operating loss carryforward benefits that begin to expire in 2026. Our foreign carryforward benefits include $784 million of net operating loss carryforwards that begin to expire in 2026. A valuation allowance is recorded to reduce the gross deferred tax assets to an amount we believe is more likely than not to be realized. The valuation allowance at December 31, 2025 was $954 million and increased by a net $82 million. The valuation allowance at December 31, 2024 was $872 million and increased by a net $83 million. The valuation allowance at December 31, 2023 was $789 million and increased by a net $85 million. The valuation allowance is primarily attributable to the uncertainty regarding the realization of a portion of the U.S. state and foreign net operating loss and tax credit carryforward benefits.

Included in the December 31, 2025, 2024 and 2023, balances are $263 million, $289 million and $314 million, respectively, related to tax positions that, if recognized, would favorably impact the effective tax rate in future periods. We also accrued interest expense related to the unrecognized tax benefits of $27 million, $31 million and $33 million as of December 31, 2025, 2024 and 2023, respectively. We recognize potential accrued interest and penalties related to unrecognized tax benefits in income tax expense.
As a result of our global operations, we file income tax returns in various jurisdictions including U.S. federal, state and foreign jurisdictions. We are routinely subject to examination by taxing authorities throughout the world, including Australia, Belgium, Brazil, Canada, China, France, India, Mexico, the U.K. and the U.S. With few exceptions, our U.S. federal, major state and foreign jurisdictions are no longer subject to income tax assessments for years before 2021.
Audit outcomes and the timing of audit settlements are subject to significant uncertainty. Although we believe that adequate provision has been made, there is the possibility that the ultimate resolution of any issues could have an adverse effect on our earnings. Conversely, if any issues are resolved favorably in the future, the related provision would be reduced, thus having a positive impact on earnings.

About Income Taxes Disclosures

The income tax disclosure reveals how much a company actually pays in taxes versus what the statutory rate would predict. Analysts focus on the effective tax rate (ETR) reconciliation, which breaks down every item driving the gap between the 21% federal rate and the company's reported ETR — including R&D credits, foreign rate differentials, and state taxes. Deferred tax assets (DTAs) and their valuation allowances signal management's confidence in future profitability: a rising allowance suggests the company doubts it can use accumulated tax benefits. Uncertain tax benefit (UTB) reserves quantify exposure to IRS challenges on aggressive positions.

Key signals to watch: sudden ETR drops without clear operational reasons, large increases in valuation allowances, growing UTB balances, and significant unremitted foreign earnings. Post-TCJA, pay attention to GILTI and BEAT provisions that affect multinational tax structures. Compare the cash taxes paid (from the cash flow statement) against the income tax provision to gauge earnings quality.
