The Company estimates the payment of approximately $5,000 of employer payroll taxes otherwise due in 2020 will be delayed with 50% due by December 31, 2021 and the remaining 50% by December 31, 2022. The CARES Act permits net operating losses from the 2018, 2019, and 2020 tax years to be carried back to the previous five tax years (beginning with the earliest year first). The Company estimates the discrete benefit associated with the net operating loss provisions of the CARES Act to be approximately $2,000 , an estimated refund of taxes paid in prior years of approximately $1,700 and the carryback additionally provides an additional refund of approximately $3,600 related to Alternative Minimum Tax credits.
