Thrift Savings Plan Match Information

Publication Date: February 17, 2021

OCSE partners with the Federal Retirement Thrift Investment Board to compare people owing child support against participants in the Thrift Savings Plan (TSP). The TSP is one of three components of the Federal Employees Retirement System for federal employees and military members. Although it's not considered a financial institution, states receive TSP quarterly match results in the Federal Case Registry “MC” Record at no additional cost.

The TSP accepts child support orders signed by a judge or authorized agent of the child support agency. States can use the fillable PDF form Thrift Savings Plan Income Withholding Order for State Agencies, TSP-CS-1 (PDF), in lieu of or in conjunction with their state-specific form to freeze and seize TSP accounts. The form includes all required information for TSP to process the order. Refer to the Thrift Savings Plan Quick Guide for Child Support Agencies.
