Income Taxes

11. Income Taxes

Deferred tax assets and liabilities are determined based on differences between financial reporting and tax basis of assets and liabilities, and are measured by applying enacted tax rates and laws for the taxable years in which those differences are expected to reverse. Deferred tax assets are evaluated for the estimated future tax effects of deductible temporary differences and tax operating loss carryovers. A valuation allowance is recorded when it is more-likely-than-not that a deferred tax asset will not be realized.

The components of income tax expense (benefit) are as follows:

	Fiscal Year Ended
	September 30, 2022			September 30, 2021			September 30, 2020

The CARES Act

In March 2020, the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) was signed into law and included various provisions to provide additional economic relief to address the impact of the COVID-19 pandemic. Notable provisions included net operating loss carrybacks, adjustments to the interest expense limitations under the U.S Tax Code Section 163(j), increase in the charitable contributions limitation, payroll tax deferrals of the employer portion of social security tax, a portion of which was repaid during the year ended September 30, 2022 and the remainder of which will be repaid in fiscal year 2023, and an employee retention

credit for wages paid to an idle employee under certain circumstances resulting from the COVID-19 pandemic. The Company recorded a tax receivable of $39.0 and a benefit of $10.1 to the tax provision for the tax net operating losses incurred in 2021 from the enactment of the CARES Act, net of adjustments. The tax net operating losses have been carried back to prior years. Further, the Company previously elected to defer the employer portion of social security taxes through 2020 and has filed for the employee retention credit allowed for under the CARES Act. The Company recorded a tax credit of $3.3 related to the employee retention credit.

Net Operating Losses

The Company has state income tax net operating losses of $157.4 having varying expirations from fiscal year 2023 through an indefinite useful life. The Company believes it is more likely than not it will be able to utilize all losses to offset future income.

Uncertain Income Tax Positions

As of September 30, 2022 and 2021, the Company had no unrecognized tax benefits that, if recognized, would impact the Company's effective tax rate. The total amount of unrecognized tax benefits could change within the next twelve months for a number of reasons including audit settlements, tax examination activities and the recognition and measurement considerations under this guidance.

The Company files income tax returns in the U.S. federal jurisdiction and various state and local jurisdictions. The Company’s returns are no longer subject to U.S. federal and state tax examination for years before 2019 and 2017, respectively.
