The employer shall furnish to all employees a written statement in a form prescribed by the state agency suitable for retention by the employees, showing the wages paid to the employee after January 1, 1953. Each statement shall cover a calendar year, or one, two or three quarters, whether or not within the same calendar year, and shall show the name of the employee, the period covered by the statement, the total amount of wages paid within such period, and the amount of tax imposed by this chapter with respect to such wages. Each statement shall be furnished to the employee not later than thirty days following the period covered by the statement, except that, if the employee leaves the employ of the employer, this final statement shall be furnished within thirty days after the last payment of wages is made to the employee. The employer may, at its option, furnish such a statement to any employee at the time of each payment of wages to the employee during any calendar quarter, in lieu of a statement covering such quarter, and, in such case, the statement may show the date of payment of wages in lieu of the period covered by the statement.
