(7) Income Taxes
The Company’s effective tax rate was 20% and 61% for the three months ended March 31, 2021 and 2022, respectively. These rates differ from the federal statutory rate of 21% due to the effect of state income taxes, certain
non-taxable
income, and certain expenses that are not deductible for tax purposes.
