5. Income Taxes

The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company has net operating losses (NOL) carried over from previous years. Therefore, the Company had no accruals for interest and penalties on the Company’s Condensed Consolidated Balance Sheets at March 31, 2022 or September 30, 2021, and has not recognized any interest or penalties in the Condensed Consolidated Statements of Operations for either of the three or six months ended March 31, 2022 or 2021.

The Company’s tax rate differs from the expected tax rate each reporting period as a result of permanent differences, the valuation allowance, international tax items, and forgiveness of the PPP loan. The Company's income tax expense for the three and six months ended March 31, 2022 and 2021 primarily consists of income tax expense/benefit at its foreign subsidiaries.
