Unusual Risk Or Uncertainty, Impact		This new legislation amended the employee retention credit to be equal to 70% of qualified wages paid to employees after December 31, 2020, and before January 1, 2022. During calendar year 2021, a maximum of $10,000 in qualified wages for each employee per qualifying calendar quarter may be counted in determining the 70% credit. Therefore, the maximum tax credit that can be claimed by an eligible employer is $7,000 per employee per qualifying calendar quarter of 2021. The Company qualifies for the employee retention credit for quarters that experience a significant decline in gross receipts, defined as quarterly gross receipts that are less than 80 percent of its gross receipts for the same calendar quarter in 2019.
