For Maine purposes, a statement must be furnished to a payee on or before the date that the related federal statement must be furnished to the payee. Under 36 M.R.S. §5251-A, a person who willfully fails to furnish a statement by the due date, or who willfully furnishes a false or fraudulent statement, commits a civil violation and is subject to a fine of $50 for each such failure or each such furnishing.
Copies of Forms W-2 provided to nonresident employees working in Maine must separately identify Maine-source income and Maine withholding in the boxes provided for state information. Public employers who participate in the Maine Public Employees Retirement System (MEPERS) must enter the employee's share of MEPERS contributions in Box 14 of Form W-2 with the designation MEPERS. Employers must maintain sufficient records to identify the Maine- source wages paid to each of their employees during the year and to document the number of days worked by each employee in Maine, even if the employee is exempt from Maine income tax or Maine withholding. In addition to following all federal legal requirements for filing Wage and Income Information Statements (such as Forms W-2, W-2G and 1099), the information filed with the Assessor must include Maine-source income and withholding information.
