TSP Rollovers Are Increasing
The Thrift Savings Plan (TSP) is growing. It now has more than $1 trillion in assets.
How does the TSP grow? Obviously, federal employees keep investing a portion of their income. These investments grow over time, and the TSP is a key element of retirement income for federal employees. The amount their money grows will help ensure a well-funded retirement income that may need to last for two or more decades.
There is another way the TSP is growing. It is probably less well known to TSP participants, but the latest data show that those rolling money into the TSP are taking advantage of this service. The Federal Retirement Thrift Investment Board just released a set of numbers that may not grab headlines but are still newsworthy.
In March 2026 alone, $220 million flowed into the TSP from outside retirement accounts. For the first quarter of 2026, that total reached $627 million. Even more telling: roughly 70% of participants bringing money into the TSP used the TSP’s “rollover concierge” service.
That combination points to a larger trend more than another routine statistic. It signals that the TSP is becoming more effective at drawing assets from outside the federal system and has been successful in making it easier to do so.
What Is the “Rollover Concierge” Service?
The concierge service is a guide through a confusing and paperwork-heavy process. This service was introduced in 2022, and with TSP data indicating that 70% are using this service, it does appear to make the process easier and provide a sense of security for those rolling over their money into the TSP.
Participants who use it are connected with a TSP representative to make it easier to move money into the TSP from some qualified accounts. The representative:
- Walks them step-by-step through the rollover process
- Coordinates directly with outside financial institutions
- Helps ensure paperwork is completed correctly
- Reduces the risk of delays or rejected transfers
In short, it removes the complexity of moving retirement assets into the TSP and ensuring all requirements are met during the transfer.
The fact that 70% of incoming rollovers now use this service suggests participants are relying on it. That level of adoption is unusually high for a relatively new administrative feature and indicates the service is doing what it was designed to do: increase the inflows of money to the TSP.
How Do These Numbers Compare?
At first glance, $627 million in a quarter may not sound dramatic for a retirement system that has over a trillion dollars in assets. Putting the numbers into context emphasizes its importance to the TSP.
Based on data from the Federal Retirement Thrift Investment Board (FRTIB) showing $1.3 billion in rollovers during the first four months of 2024, and annual rollover data suggests TSP inflows appear to be in the range of several billion dollars. In 2024, the TSP was experiencing rollovers at the rate of 5000-6000 per month.
Recent data shows the TSP has been bringing in about $2.5–$3 billion annually in rollovers, depending on monthly variation. At the current pace, this year’s first-quarter total is in line with that trend. To borrow from a phrase reportedly popularized by Senator Everett Dirksen: “A billion here, a billion there, and pretty soon you’re talking real money.”
This is not a sudden spike. It is a sustained, consistent inflow of outside retirement money transferring into the TSP.
While rollovers are still relatively small compared to total TSP cash flows (which include tens of billions in annual contributions and withdrawals), they represent a strategic source of growth. Here is why:
- They bring in new assets, not tied to federal payroll
- They often involve large, one-time transfers
- They reflect participants making active, deliberate financial decisions
Where Is the Money Coming From?
The rollover dollars entering the TSP are largely coming from:
- Private-sector 401(k) plans
- Traditional IRAs
- Other eligible employer-sponsored retirement accounts
In practical terms, this means:
- New federal employees are bringing savings from prior careers into the TSP
- Current employees are consolidating multiple retirement accounts
- Some participants simply prefer the TSP’s structure over private-sector alternatives
Why Participants Move Money Into the TSP
There are several reasons why these retirement assets from outside sources are moving into the TSP:
- Low administrative costs compared to many private plans
- The simplicity of consolidating accounts into one place
- Access to unique TSP features, particularly the G Fund
- The TSP offers a variety of index funds that are easy to understand and use to build an investment portfolio
For many participants, the decision is probably less about chasing returns and more about reducing complexity and investment costs over the length of their federal careers.
What This Trend Really Means
These rollover figures highlight a shift that will help the TSP continue to grow.
The TSP is no longer just a passive destination for payroll contributions from federal employees. With the concierge service, the TSP is an active competitor for investing retirement assets.
The high usage rate of the concierge service demonstrates TSP participants find it useful. The steady inflow of billions of dollars each year confirms this is a durable trend.
The Bottom Line
The latest data from the Federal Retirement Thrift Investment Board shows the TSP is steadily attracting outside retirement money into the TSP, and the concierge service is making it easier to do so.
The headline numbers may not look dramatic at first glance. But taken together, they point to something more meaningful:
The TSP is quietly growing not just from within but also by pulling billions in assets in from outside the federal government as well.
