Income Tax Disclosure [Abstract] |
Income Taxes | NOTE J – INCOME TAXES Current fiscal year Ashland’s effective tax rate in any interim period is subject to adjustments related to discrete items and the mix of domestic and foreign operating results. The overall effective tax rate was 34% and 25% for the three and six months ended March 31, 2022. The current quarter tax rate was impacted by jurisdictional income mix, as well as $7 million from net unfavorable tax discrete items primarily related to restructuring and separation activity partially offset by a favorable valuation allowance adjustment for certain foreign tax credits. The current six month tax rate was impacted by jurisdictional income mix as well as $5 million from net unfavorable tax discrete items primarily related to restructuring and separation activity partially offset by a favorable valuation adjustment for certain foreign tax credits and adjustments to uncertain positions. Prior fiscal year The overall effective tax rate was a benefit of 26% for the three months ended March 31, 2021 and a benefit of 17% for the six months ended March 31, 2021. The quarter tax rate was primarily impacted by jurisdictional income mix, as well as $7 million from favorable tax discrete items primarily related to uncertain tax positions. The six months tax rate impacted by $20 million from favorable tax discrete items primarily related to the Specialty Additives facility sale and uncertain tax positions. Unrecognized tax benefits Changes in unrecognized tax benefits are summarized as follows for the six months ended March 31, 2022.

From a combination of statute expirations and audit settlements in the next twelve months, Ashland expects a decrease in the amount accrued for uncertain tax positions of between $6 million and $16 million for continuing operations. It is reasonably possible that there could be other material changes to the amount of uncertain tax positions due to activities of the taxing authorities, settlement of audit issues or the reassessment of existing uncertain tax positions; however, Ashland is not able to estimate the impact of these items at this time.
