On Friday, October 30, the IRS provided guidance regarding the proper reporting on Form W-2 for employers who deferred the withholding of the employee share of Social Security tax under Notice 2020-65. (See earlier coverage.) Based on the IRS guidance, employers should report FICA wages up to the OASDI (Social Security) wage base in Box 3 of the 2020 Form W-2. Only the amount of Social Security tax actually withheld during 2020 should be reported in Box 4 of the form.
In 2021, if the employer withholds the 2020 deferred Social Security taxes, the employer must file a Form W-2c for 2020 reporting the additional withholding in Box 4. Although the IRS guidance does not address this, if the employer pays in 2021 the employee’s share of Social Security taxes that were deferred in 2020, the employer must still file a Form W-2c reporting the amount as withheld Social Security taxes in Box 4. Moreover, the employer would also be required to include the amount of taxes paid by the employer on the employee’s behalf as additional wages in Boxes 1, 3 (up to the OASDI wage base), and 5 on the employee’s 2021 Form W-2. Because the employer’s payment of the employee’s deferred tax constitutes additional wages to the employee in 2021, these amounts will need to be grossed up to account for employment taxes on the amount of the employee’s tax paid by the employer if those taxes are not withheld from the employee’s other 2021 wages.
