Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our interim income tax provisions are based on the effective income tax rate expected to be applicable for the full fiscal year, adjusted for specific items that are required to be recognized in the period in which they occur. Deferred tax assets and liabilities are based on the enacted tax rate that will apply in future periods when such assets and liabilities are expected to be settled or realized. Our effective income tax rate was 26.3% and 24.9% for the three months ended July 31, 2021 and July 25, 2020, respectively, and 16.5% and 76.4% for the six months ended July 31, 2021 and July 25, 2020, respectively. The effective tax rate differs from the statutory rate primarily due to the impact of the vesting and exercise of share-based awards during the six months ended July 31, 2021. Other fluctuations in our effective income tax rate from the statutory rate each period are mainly attributable to the difference in income tax rates from state to state where work was performed, changes in unrecognized tax benefits, tax law changes, tax credits recognized, and variances in non-deductible and non-taxable items. Additionally, during the six months ended July 25, 2020, our effective tax rate was impacted by the $53.3 million goodwill impairment charge which was mostly non-deductible for income tax purposes, and the benefit from the $2.6 million tax loss carryback technical correction under the CARES Act. During the second quarter of fiscal 2022, we were notified by the Internal Revenue Service that our federal income tax return for fiscal 2020 was selected for examination. We believe our provision for income taxes is adequate; however, any assessment may affect our results of operations and cash flows.
