INCOME TAXES

The determination of the Company’s overall effective income tax rate requires the use of estimates. The effective income tax rate reflects the income earned and taxed in U.S. federal and various state jurisdictions based on enacted tax law, permanent differences between book and tax items, tax credits and the Company’s change in relative income in each jurisdiction.

The Company estimated its annual effective income tax rate for the full fiscal year and applied the annual effective income tax rate to the results of the 13 weeks ended March 28, 2020 and March 30, 2019 for purposes of determining its year-to-date tax provision.

For the 13 weeks ended March 28, 2020, the Company's effective income tax rate of 23% differed from the 21% federal corporate income tax rate primarily as a result of state income taxes and the recognition of various discrete tax items. These discrete tax items included tax expense of $3 million primarily related to an increase in the state valuation allowance. For the 13 weeks ended March 30, 2019, the Company's effective income tax rate of 22% differed from the 21% federal corporate income tax rate primarily as a result of state income taxes and the recognition of various discrete tax items. These discrete tax items included a tax benefit of $2 million, primarily related to the reduction of an unrecognized tax benefit following a lapse of the statute of limitations and a tax benefit of $1 million, primarily related to excess tax benefits associated with share-based compensation.
