A thrift savings plan (TSP) is a retirement investment program that is exclusively available to federal employees and members of the uniformed services. While TSP shares some similarities with other retirement plans, there are distinct differences that federal employees and service members should be aware of.

One of the primary differences between a thrift savings plan and other retirement plans is its exclusivity. The TSP is specifically designed for federal employees and uniformed service members, including the Ready Reserve. This sets it apart from other retirement plans that are available to workers in the private sector.

Similar to a 401(k) plan offered by private employers, the TSP is a defined contribution (DC) plan. This means that participants have control over the contributions they make to the plan and the investment options available to them. The contributions made by employees are tax-deferred, providing an immediate tax break. Alternatively, participants can choose to invest in a Roth option within the TSP, which allows for tax-free withdrawals in retirement.

When it comes to investment options, the TSP offers a selection of six different investment funds. These include five index funds and a series of target-date funds that blend the index funds. While the investment options may be more limited compared to some other retirement plans, they still provide participants with the opportunity to diversify their portfolios and potentially earn returns over time.

Another significant difference between the TSP and other retirement plans is the fee structure. The TSP generally has lower fees compared to most 401(k) plans. This can be beneficial for participants as lower fees can help maximize the growth of their retirement savings over time.

In terms of employer contributions, federal employees typically receive a flat 1% employer contribution as well as a match for most employees. The match is usually a 100% match up to 3% of employee compensation, and then a 50% match up to 5%, with no matching over that. However, it's important to note that most military service members do not receive a matching contribution.

One important consideration for federal employees is the restrictions on partial withdrawals from the TSP. If a federal employee makes an age-based in-service withdrawal of only part of their account balance, they may become ineligible to make a partial withdrawal in the future, even after being separated from service. In such cases, the only option available would be a full distribution of some form.

Furthermore, the TSP allows for portability. If an individual leaves the private sector to work in a public sector job, they can roll over their 401(k) and IRAs into a TSP. Similarly, if a participant leaves a public service job with a TSP, they have the option to roll it over to a 401(k) or IRA.

In conclusion, a thrift savings plan (TSP) is a retirement investment program exclusively available to federal employees and uniformed service members. While it shares similarities with other retirement plans, such as the tax advantages and investment options, there are distinct differences to consider. The TSP offers lower fees, limited investment options, specific employer contribution structures, and restrictions on partial withdrawals. Understanding these differences can help federal employees and service members make informed decisions about their retirement savings and investment strategies.

Summary:
The main difference is that the TSP is only for Federal employees. A Thrift Savings Plan is essentially a 401(k) for employees of the federal government. It functions in the same ways and is subject to the same limitations. The contribution limits and catch-up limits are the same, as well as the employer contribution limit.

The plan actually has lower fees than most 401(k)s, so that’s one difference. The investment options are fairly limited, but not much more than regular 401(k)s. There are basically 5 index funds to choose from and then a series of target-date funds that blend the index funds.

There is usually a flat 1% employer contribution as well as a match for most employees, but not for most military service members. The match is usually a 100% match up to 3% of employee compensation, and then a 50% match up to 5%, with no matching over that.

Another difference from most 401(k)s is that if a Federal Employee makes an age-based in-service withdrawal of only part of their account balance, he or she may not be eligible to make a partial withdrawal ever again, including after being separated from service. At that point the only option would be a full distribution of some form.
