Wage Hour Form 347 is a federal payroll form that contractors fulfilling Davis-Bacon Act contracts can choose to use when they report payrolls each week, according to the U.S. Department of Labor. The form and instructions are available at DOL.gov under the Wage and Hour Division as of 2015.
Under the Davis-Bacon Act, contractors and subcontractors on construction projects receiving federal assistance must pay wages in accordance with the prevailing wage rate for the work each employee performed. Federal law requires that they make weekly reports of their wage payrolls and certify that their reports are correct. The purpose of Form 347 is to make it easier for contractors to provide the information, although the law does not require that they use the form to satisfy the reporting requirements, explains the U.S. Department of Labor.
