One of the most frequent and harmful IRS tax violations is the failure of an employer to send payroll taxes to the IRS that it has withheld from its employees pay.
The payroll taxes an employer holds back from an employee ("trust fund") never belongs to the employer, but rather are held in a constructive trust for the federal government; Thus, every employer has a fiduciary duty to properly report and turn over all withheld taxes. If you don't do it, it is considered to be theft of government funds. Even though it is very unlikely the IRS would pursue criminal charges for this, they do have the ability to do so.
