In an effort to prevent identity theft, California has passed Senate Bill 1618. The Bill, which amends Labor Code 226(7), requires that pay stubs or itemized wage statements use either (1) no more than the last four digits of an employee's social security number, or (2) an employee identification number other than the social security number. Employers must implement the change by January 1, 2008 or otherwise risk penalties of up to $100 per employee, per pay period, to a maximum of $4,000, per employee.
