If you own or manage a business with employees, you may be at risk for a severe tax penalty. It’s called the “Trust Fund Recovery Penalty” because it applies to the Social Security and income taxes required to be withheld by a business from employees’ wages. Because the taxes are considered government property, the employer holds them in “trust” on the government’s behalf until they’re paid over. The penalty is also sometimes called the “100% penalty” because the person liable and responsible for the taxes will be penalized 100% of the taxes due. Accordingly, the amounts IRS seeks when the penalty is applied are usually substantial, and IRS is very aggressive in enforcing this penalty.
