The Thrift Savings Plan (TSP) is a defined contribution plan for United States civil service employees and retirees as well as for members of the uniformed services. As of December 31, 2023, TSP has approximately 7 million participants (of which approximately 4.1 million are actively participating through payroll deductions), and more than $845.4 billion in assets under management;[1] it purports to be the largest defined contribution plan in the world. The TSP is administered by the Federal Retirement Thrift Investment Board, an independent agency.[a]
The TSP is one of three components of the Federal Employees Retirement System (FERS; the others being the FERS annuity and Social Security) and is designed to closely resemble the dynamics of private sector 401(k) and Roth 401k plans (TSP implemented a Roth option in May 2012). It is also open to employees covered under the older Civil Service Retirement System (CSRS) but with far fewer benefits (mainly the lack of matching contributions).
