Income Taxes	12. Income Taxes An income tax expense of $723 thousand was recorded for the three months ended March 31, 2021 compared to an income tax expense of $1.2 million in the same period of 2020. An income tax expense of $833 thousand was recorded for the six months ended March 31, 2021 compared to income tax expense of $1.0 million in the same period of 2020. The income tax expense for the three and six months ended March 31, 2021 is primarily driven by an increase in the valuation allowance against deferred tax assets in the period, offset by a benefit recorded for a change in tax law, allowing for the immediate deduction of covered expenses incurred through the Paycheck Protection Program. The deferred tax asset change is a non-cash item. The income tax expense for the six months ended March 31, 2020 reflected the recording of a valuation allowance against deferred tax assets during the second fiscal quarter, offset by the anticipated tax benefit from the carryback of net operating losses. The provisions above are estimates, and accordingly, changes to these estimates will be recorded in subsequent periods as more information and guidance becomes available.
