US NEWS TAXCHEATS-IRS 3 WA

Workers enter the IRS building on Dec. 11, 2014 in Washington, D.C. A 1978 provision, known as the safe harbor, provides blanket protection to tens of thousands of business to identify their workers as independent contractors for tax purposes even though the worker is, in fact, an employee. Experts say the safe harbor is one of the greatest barriers to IRS collecting taxes on companies who misclassify their workers. (Molly Riley/McClatchyDC/TNS)
