Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes During the six months ended June 30, 2025, gross unrecognized tax benefits decreased by $1.3 million to $12.9 million. The decrease is primarily related to statute expirations and true-up estimates, partially offset by recording U.S. and non-U.S. reserves and foreign exchange. If recognized, approximately $9.5 million in unrecognized tax benefits would affect our effective tax rate and net earnings in future periods. We recognize interest and penalties related to unrecognized tax benefits as a component of our income tax provision. We had accrued interest and penalties totaling $5.4 million as of June 30, 2025 and December 31, 2024, respectively, that were included in other noncurrent liabilities in the Condensed Consolidated Balance Sheets. Accounting for uncertain tax positions is determined by prescribing the minimum probability threshold that a tax position is more likely than not to be sustained based on the technical merits of the position. Mosaic is continually under audit by various authorities in the normal course of business. Such tax authorities may raise issues contrary to positions taken by the Company. If such positions are ultimately not sustained by the Company, this could result in material assessments to the Company. The costs related to defending, if needed, such positions on appeal or in court may be material. The Company believes that any issues raised have been properly accounted for in its current financial statements. For the three months ended June 30, 2025, discrete tax items recorded in tax expense was a expense of approximately $1.0 million. The net tax expense consisted primarily of changes in valuation allowance and share-based excess costs. In addition to items specific to the period, our income tax rate is impacted by the mix of earnings across the jurisdictions in which we operate, by a benefit associated with depletion, and by the impact of certain entities being taxed in both their foreign jurisdiction and the U.S., including foreign tax credits for various taxes incurred. Generally, for interim periods, income tax is equal to the total of (1) year-to-date pretax income multiplied by our forecasted effective tax rate, plus (2) tax expense items specific to the period. In situations where we expect to report losses for which we do not expect to receive tax benefits, we are required to apply separate forecasted effective tax rates to those jurisdictions rather than including them in the consolidated effective tax rate. For the three months ended June 30, 2025, income tax expense was impacted by this set of rules, resulting in increased expense of $0.4 million compared to what would have been recorded under the general rule on a consolidated basis. For the six months ended June 30, 2025, discrete tax items recorded in tax expense was a benefit of approximately $25.2 million. The net tax benefit consisted primarily of changes in valuation allowance, share-based costs, true-up of estimates, and other miscellaneous costs. In addition to items specific to the period, our income tax rate is impacted by the mix of earnings across the jurisdictions in which we operate, by a benefit associated with depletion, and by the impact of certain entities being taxed in both their foreign jurisdiction and the U.S., including foreign tax credits for various taxes incurred.
