INCOME TAXES

The determination of the Company’s overall effective tax rate requires the use of estimates. The effective tax rate reflects the income earned and taxed in various United States federal and 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 tax rate for the full fiscal year and applied the annual effective tax rate to the results of the 26 weeks ended June 29, 2019 and June 30, 2018 for purposes of determining its year-to-date tax provision.

For the 13 weeks ended June 29, 2019, the Company's effective income tax rate of 25% 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 excess tax benefits associated with share-based compensation. For the 13 weeks ended June 30, 2018, 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 $4 million resulting from the change in a provisional estimate related to the reduction of the federal corporate income tax rate under the Tax Act and a tax benefit of $3 million primarily related to excess tax benefits associated with share-based compensation.

For the 26 weeks ended June 29, 2019, the Company's effective income tax rate of 24% 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 $3 million primarily related to excess tax benefits associated with share-based compensation. For the 26 weeks ended June 30, 2018, the Company's effective income tax rate of 14% 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 $17 million primarily related to the reduction of an unrecognized tax benefit due to the receipt of an affirmative written consent from the IRS to change a method of accounting, a tax benefit of $5 million primarily related to excess tax benefits associated with share-based compensation and a tax benefit of $4 million resulting from the change in a provisional estimate related to the reduction of the federal corporate income tax rate under the Tax Act.
