(14) Income Taxes

The effective income tax rate for the six months ended June 30, 2022 is 0%, compared with an effective tax rate of 0% for the year ended December 31, 2021. The calculation of the annual effective tax rate did not produce a reliable estimate, so the actual effective tax rate for the year-to-date period is used as the best estimate of the annual effective tax rate.

Starting in 2022, Tax Cuts and Jobs Act amendments to Internal Revenue Code Section 174 will no longer permit an immediate deduction for research and development expenditures in the tax year that such costs are incurred. The 2022 first quarter effective income tax rate was impacted by the Section 174 capitalization requirement combined with the restriction on net operating losses to only reduce taxable income by 80%.

The Company continues to record a valuation allowance on its net deferred tax assets. The valuation allowance increased by approximately $2.9 million during the six months ended June 30, 2022. The Company has not recognized any reserves for uncertain tax positions.
