CY2021	bdr	Maximum Credit Description MaximumCreditDescription	The CAA and ARPA amendments to the ERTC program provide eligible employers with a tax credit in an amount equal to 70% of qualified wages (including certain health care expenses) that eligible employers pay their employees after January 1, 2021 through September 30, 2021. The maximum amount of qualified wages taken into account with respect to each employee for each calendar quarter is $10,000, so that the maximum credit that an eligible employer may claim for qualified wages paid to any employee is $7,000 per quarter. For purposes of the amended ERTC, an eligible employer is defined as having experienced a significant (20% or more) decline in gross receipts during each 2021 calendar quarter when compared with the same quarter in 2019. The credit is taken against the Company’s share of Social Security Tax when the Company’s payroll provider files the applicable quarterly tax filings on Form 941. At June 30, 2022, the Company is still owed $319 in ERTC funds which it expects to receive during the fourth quarter of 2022.
