Understanding Box 13 Information
On the W-2 form, Box 13 has various sections for information that the government has defined. To enter information in Box 13, you must first set values in different sections of the U.S. Year-End Payroll system.
Box 13 contains these categories:
Statutory employee.
Retirement plan.
Third-party sick pay.
The Statutory employee category is government-defined. You use it to specify whether an employee is statutory or not. A statutory employee is not subject to federal income tax withholding, but is subject to Social Security and Medicare tax.

Reviewing Employee Form Information.
You also use Box 13 to specify whether an employee is an active member in a retirement savings plan, or whether the employee received third-party sick pay during the tax-reporting year.
