Williamson County is a member of the Texas County and District Retirement System (TCDRS).
Retirement deductions are mandatory and are withheld from employee paychecks at the rate of 7% (as of 1/1/97) of gross pay. These deductions are made prior to the calculation of the employee's tax liability (i.e., these are pretax deductions).
The county provides matching funds according to actuarial projections. Members are vested and eligible for full service retirement benefits if they have accumulated at least 8 years of credited service and have attained the age of 60 OR their age plus accumulated years of credited service (4 years minimum if employed prior to 1/1/2000, 8 years minimum if employed on or after 1/1/2000) equals 75 OR they have 30 years of credited service regardless of their age.
