Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The effective tax rate for the second quarter of 2023 was 24.2 percent on a pre-tax loss, compared to (38.3) percent on pre-tax income in the prior year. The primary factor that impacted the comparison of these rates was the second quarter 2022 charge related to steps toward resolving Combat Arms Earplugs litigation (see Note 14). The effective tax rate for the first six months of 2023 was 25.2 percent, compared to 16.8 percent in the prior year. The primary factor that impacted the comparison of the six-month rates was the second quarter 2023 charge related to the proposed settlement agreement with public water systems in the United States regarding PFAS (discussed in Note 14). The total amounts of unrecognized tax benefits that, if recognized, would affect the effective tax rate as of June 30, 2023 and December 31, 2022 are $989 million and $965 million, respectively. It is reasonably possible that the amount of unrecognized tax benefits could significantly change within the next 12 months. At this time, the Company is not able to estimate the range by which these potential events could impact 3M’s unrecognized tax benefits in the next 12 months. At June 30, 2023, 3M’s deferred tax assets, a component of other assets on the consolidated balance sheet, also included a balance of approximately $2.4 billion as a result of the pre-tax charge related to the proposed settlement agreement announced in the second quarter of 2023 with public water systems in the United States regarding PFAS (see Note 14). As of June 30, 2023 and December 31, 2022, the Company had valuation allowances of $128 million and $115 million on its deferred tax assets, respectively.
