Note: The Coronavirus Aid, Relief, and Economic Security (CARES) Act provides some payroll tax relief for employers. Specifically, it allows employers to delay their payment of the employer share (6.2% of wages) of the Social Security payroll tax. These taxpayers can pay the tax over the next two years, with the first half due by December 31, 2021, and the second half due by December 31, 2022. Self-employed individuals receive similar relief under the law.
