If an incorrect cost center or object code was used for labor distribution in a prior pay period, a reallocation transaction is used to correct the error. 

If a reallocation is required, the department should send a memo or e-mail to the Payroll Department requesting the correction.  All memos are due in the Payroll Department by the last week of every month.

W-2 forms are mailed out to the employee's system address by January 31 of each year as required by Federal law.
