Just a week after asking in a letter to Treasury Secretary Steve Mnuchin for clarity on President Trump’s Executive Order allowing deferral of Social Security payroll taxes, the  US Chamber of Commerce this week came out in opposition to it. In a letter sent this week to Mnuchin, Speaker of the House Pelosi and Senate Majority Leader McConnell, the Chamber along with more than 30 Washington DC business groups, called the President’s directive “unworkable” for most employers and projected that it would create a substantial tax liability for employees at the end of the year. As signed by the President, the Executive Order authorized employers to defer the withholding of the employee share of social security payroll taxes from September 1 through December 31, 2020. Earlier in the week, Mnuchin clarified that the order would only be available for employees paid less than $4000 bi-weekly and that business participation was voluntary. Notwithstanding, the chamber cited an internal analysis showing that under the deferral provisions, an employee making $75,000 per year would owe $1600 in additional taxes at year-end.
