8. Tax Matters
A. Taxes on Income
On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was enacted into law in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain tax provisions that were originally enacted in the 2017 Tax Cuts and Jobs Act and were set to expire on December 31, 2025, modifications to certain international tax provisions and the restoration of tax treatment for certain business provisions, including 100% bonus depreciation for certain qualified property, domestic research and experimental cost expensing, and the business interest expense limitation. The new legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. We do not currently expect OBBBA to have a material impact on our financial results, including the effect on our effective tax rate and deferred tax assets and liabilities in 2025 and future periods.
The income tax provision in the Consolidated Statements of Income includes tax costs and benefits, such as uncertain tax positions, repatriation decisions and audit settlements, among others.

Our effective income tax rate was 20.4%, 20.3% and 20.3% in 2025, 2024 and 2023, respectively.
The higher effective tax rate for 2025, as compared to 2024, was primarily attributable to a lower benefit in the U.S. related to foreign-derived intangible income, partially offset by a more favorable jurisdictional mix of earnings (which includes the impact of the location of pre-tax earnings, tax impact of permanent differences and repatriation activity) and higher net discrete tax benefits.
The effective tax rate for 2024, as compared to 2023, was primarily attributable to the favorable impact of a higher benefit in the U.S. related to foreign-derived intangible income and lower net discrete tax expenses, offset by a less favorable jurisdictional mix of earnings (which includes the impact of the location of earnings, repatriation costs and Pillar Two global minimum tax). Jurisdictional mix of earnings can vary depending on repatriation decisions, operating fluctuations in the normal course of business and the impact of non-deductible items and non-taxable items.
In 2022 and 2024, the company implemented an initiative to maximize its cash position in the U.S. This initiative resulted in a tax benefit in the U.S. in connection with a prepayment from a related foreign entity in Belgium which qualifies as foreign-derived intangible income; however, the 2022 income tax benefit was deferred and recognized in 2023 and 2024 and the 2024 income tax benefit was deferred to 2025 and 2026. A portion of the 2024 benefit was recognized during 2025. The remaining deferred benefit is included in Other current assets on our Consolidated Balance Sheets as of December 31, 2025 in the amount of $19 million.

B. Deferred Taxes
Deferred taxes arise as a result of basis differentials between financial statement accounting and tax amounts.

$498 $373 
(a)    The change in the total net deferred tax asset/(liability) from December 31, 2024 to December 31, 2025 is primarily attributable to an increase in deferred tax assets related to (i) the capitalization and amortization of research and development costs for U.S. tax purposes, (ii) foreign exchange (gains)/losses, (iii) original issue discount on convertible debt, and (iv) net operating loss/credit carryforwards, partially offset by a decrease in deferred tax assets related to (i) prepaid/deferred items as a result of a prepayment from a related foreign entity in Belgium, as well as an increase in valuation allowance.
(b)    In 2025, included in Noncurrent deferred tax assets ($637 million) and Noncurrent deferred tax liabilities ($139 million). In 2024, included in Noncurrent deferred tax assets ($540 million) and Noncurrent deferred tax liabilities ($167 million).
We have carryforwards, primarily related to net operating losses, which are available to reduce future foreign, U.S. federal, and U.S. state income taxes payable with either an indefinite life or expiring at various times from 2026 to 2045.
Valuation allowances are provided when we believe that our deferred tax assets are not recoverable based on an assessment of estimated future taxable income that incorporates ongoing, prudent and feasible tax planning strategies. On the basis of this evaluation, as of December 31, 2025 and 2024, a valuation allowance of $185 million and $123 million, respectively, has been recorded to reflect only the portion of the deferred tax asset that is more likely than not to be realized. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased or if objective negative evidence in the form of cumulative losses is no longer present and additional weight may be given to subjective evidence such as projections for growth.
In general, it is our practice and intention to permanently reinvest the majority of the earnings of the company’s non-U.S. subsidiaries. As of December 31, 2025, we have not provided U.S. and local income taxes, such as U.S. state income taxes, local withholding taxes, and taxes on currency gains and losses for the cumulative amount of such undistributed earnings. Since these earnings are intended to be indefinitely reinvested overseas as of December 31, 2025, we cannot predict the time or manner of a potential repatriation. As such, other than the deferred tax liability associated with the one-time mandatory deemed repatriation tax on such undistributed earnings imposed by the Tax Cuts and Jobs Act of 2017, it is not practicable to estimate the additional deferred tax liability associated with the potential repatriation of the unremitted earnings.
C. Tax Contingencies
We are subject to income tax in many jurisdictions, and a certain degree of estimation is required in recording the assets and liabilities related to income taxes. All of our tax positions are subject to audit by the local taxing authorities in each tax jurisdiction. These tax audits can involve complex issues, interpretations and judgments and the resolution of matters may span multiple years, particularly if subject to negotiation or litigation. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but our estimates of unrecognized tax benefits and potential tax benefits may not be representative of actual outcomes, and variation from such estimates could materially affect our financial statements in the period of settlement or when the statute of limitations expire. We treat these events as discrete items in the period of resolution.
For a description of our accounting policies associated with accounting for income tax contingencies, see Note 3. Significant Accounting Policies: Deferred Tax Assets and Liabilities and Income Tax Contingencies. For a description of the risks associated with estimates and assumptions, see Note 3. Significant Accounting Policies: Estimates and Assumptions.
Uncertain Tax Positions
As tax law is complex and often subject to varied interpretations, it is uncertain whether some of our tax positions will be sustained upon audit. As of December 31, 2025, 2024 and 2023, we had approximately $222 million, $214 million and $209 million, respectively, in net liabilities associated with uncertain tax positions, excluding associated interest and penalties. As of December 31, 2025, 2024 and 2023, we had approximately $1 million,
$1 million and $0 million, respectively, in assets associated with uncertain tax benefits recorded in Noncurrent deferred tax assets and Other noncurrent assets.
Tax liabilities associated with uncertain tax positions represent unrecognized tax benefits, which arise when the estimated benefit recorded in our financial statements differs from the amounts taken or expected to be taken in a tax return because of the uncertainties described above. These unrecognized tax benefits relate primarily to issues common among multinational corporations. Substantially all of these unrecognized tax benefits, if recognized, would impact our effective income tax rate.
The reconciliation of the beginning and ending amounts of gross unrecognized tax benefits follows:

Interest related to our unrecognized tax benefits is recorded in accordance with the laws of each jurisdiction and is recorded in Provision for taxes on income in our Consolidated Statements of Income. We recorded net interest expense of $14 million, $12 million and $10 million in 2025, 2024 and 2023, respectively. Gross accrued interest totaled $51 million, $37 million and $26 million as of December 31, 2025, 2024 and 2023, respectively, and were included in Other taxes payable. As of December 31, 2025, 2024 and 2023, gross accrued penalties totaled $1 million and were included in Other taxes payable.
Status of Tax Audits and Potential Impact on Accruals for Uncertain Tax Positions
We are subject to taxation in the U.S. including various states, and foreign jurisdictions. The U.S. is one of our major tax jurisdictions, and we are currently under income tax audit by the U.S. Internal Revenue Service (IRS) for tax years 2017 through 2018. For U.S. state tax purposes, tax years 2017 through 2024 are open for examination. In July 2024, the IRS issued Notices of Proposed Adjustment (NOPA) related to the one-time mandatory deemed repatriation tax incurred on the 2018 U.S. Federal Income Tax return. In September 2024, the IRS issued a Revenue Agent Report (RAR) for the adjustments identified in the NOPA and a protest was filed with the IRS on November 15, 2024. As of December 31, 2025, the additional tax liability, based on the income adjustment proposed by the IRS under the RAR, is approximately $450 million, excluding interest and penalties.
Based on current facts and circumstances, we disagree with the IRS' position and will defend our position taken on the 2018 U.S. Federal Income tax return. We believe the amount previously accrued related to this uncertain tax position remains appropriate, but we will continue to evaluate the adequacy of our tax reserve as the audit progresses. However, the outcome of the tax audits cannot be predicted with certainty. If any issues addressed in our tax audits are not consistent with management's expectations, we could be required to adjust our provision for income taxes and this amount could be material to our financial statements.
In addition to the open audit years in the U.S., we have open audit years in other major foreign tax jurisdictions, such as Canada (2022-2025), Asia-Pacific (2015-2025, primarily reflecting Australia, China and Japan), Europe (2013-2025, primarily reflecting France, Germany, Italy, Spain and the U.K.) and Latin America (2016-2025, primarily reflecting Brazil and Mexico).
Any settlements or statute of limitations expirations could result in a significant decrease in our uncertain tax positions. Our assessments are based on estimates and assumptions that have been deemed reasonable by management, but our estimates of unrecognized tax benefits and potential tax benefits may not be representative of actual outcomes, and any variation from such estimates could materially affect our financial statements in the period of settlement or when the statutes of limitations expire, as we treat these events as discrete items in the period of resolution. Finalizing audits with the relevant taxing authorities can include formal administrative and legal proceedings, and, as a result, it is difficult to estimate the timing and range of possible change related to our uncertain tax positions, and such changes could be significant.

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.
