6 Questions to Ask Before You Move a TSP Balance Into an IRA
Sam's List Editorial | 2026-09-04
A TSP rollover to IRA gets pitched as an upgrade. More investment choices, more flexibility, one less login. Sometimes that is exactly right.
What nobody mentions in the sales conversation is that the Thrift Savings Plan has four features that do not exist in an IRA, and once the money leaves, three of them are gone for good. Whether that matters depends entirely on your age, your balance, and what you plan to do with the money in the next ten years.
Six questions sort it out. Here is the short version of what stays behind.
| Feature | Thrift Savings Plan | Traditional IRA |
|---|---|---|
| Penalty-free withdrawals after separating at 55+ | Yes | No, generally 59½ |
| G Fund | Available | No direct equivalent |
| Core fund expense ratios | Around 0.04% | Depends entirely on what you buy |
| Investment menu | Limited to plan funds | Broad |
| Lifetime RMDs on Roth money | No, since 2024 | No |
| Plan loans | Available while employed | Not available |
1. Does the Age-55 Separation Exception Matter to You?
This is the one that costs people real money. If you separate from federal service in or after the year you turn 55, TSP withdrawals are exempt from the 10% early withdrawal penalty, even before age 59½. For public safety employees the age is 50.
That exception belongs to the plan, not to you. Roll the money into a traditional IRA and the IRA rules apply, which means a 10% additional tax on distributions before 59½ unless a separate exception fits.
So if you retired at 56 and expect to draw on this money before 59½, moving it can create a penalty that did not exist an hour earlier. If you are 62 and not touching it until 70, this question does not apply to you at all.
2. Can You Replace the G Fund?
The G Fund has no direct commercial equivalent. It holds special-issue Treasury securities available only to the plan, and it is structured so the share price does not decline while it earns a long-term Treasury-based rate.
Outside the TSP, the closest substitutes are short-term Treasury funds, money market funds, and stable-value products, and each of them behaves differently in a rising-rate environment. None of them replicate the specific combination.
If the G Fund is where your stability allocation lives, one option is a partial transfer: move the equity portion out and leave the G Fund balance in the plan. That preserves the feature and still gets you the flexibility, at the cost of maintaining two accounts.
3. What Are You Actually Paying Now Versus After?
The TSP's core funds carry expense ratios in the neighborhood of 0.04%, which is at the low end of what exists anywhere. An IRA can match that with index funds and can also cost dramatically more, depending on what goes into it and whether an advisory fee is layered over it.
Get both numbers in writing before you decide. Not "it's competitive." The actual all-in figure: fund expenses plus any advisory fee plus any platform fee, expressed as a percentage and as dollars on your balance.
Lower cost is not the only thing that matters, and paying for advice you use can be worth it. But you should know the number you are trading up to, because on a large balance a difference of half a percent compounds into a meaningful figure over twenty years.
4. Do You Have Roth TSP Money, and Do You Know the RMD Rules Changed?
SECURE 2.0 eliminated lifetime required minimum distributions from designated Roth accounts in employer plans, including the Roth TSP, effective for taxable years beginning after December 31, 2023.
This matters because avoiding RMDs used to be a standard reason to roll a Roth TSP to a Roth IRA. That reason is retired. There may still be good arguments for consolidating, including investment options and simpler beneficiary administration, but the RMD argument no longer holds.
One rule that did not change: the Roth IRA five-year clock. Your Roth TSP holding period does not automatically carry over to a Roth IRA for all purposes, so if your Roth IRA is newly opened, confirm how the timing works for your situation before you assume earnings are freely accessible.
5. Is There an Outstanding TSP Loan?
An unpaid TSP loan generally has to be resolved when you separate or when you move the money. If it is not repaid, the outstanding balance is typically treated as a taxable distribution, and if you are under 59½ without an applicable exception, an additional tax can also apply.
Check the balance and the repayment deadline before initiating anything. This is a sequencing problem with a clean answer, and it only becomes expensive when the transfer happens first and the loan is discovered second.
6. TSP Rollover to IRA by Direct Transfer, or Check in the Mail?
A direct rollover moves the money custodian to custodian and avoids the mandatory 20% federal withholding that applies to an eligible rollover distribution paid to you.
With an indirect rollover you receive the money, 20% is withheld, and you have 60 days to deposit the full original amount, including the withheld portion, out of your own pocket to avoid tax on the shortfall. People do this by accident and discover it in April.
Also worth knowing: it is possible in some circumstances to transfer traditional IRA money back into the TSP if you are still an eligible participant. Once you have separated and closed the account, that door is generally shut. Ask about it before you close anything.
Where a Second Opinion on a TSP Rollover to IRA Helps
None of these six questions is hard on its own. What makes the decision hard is that they interact. The age-55 answer changes the withdrawal plan, the withdrawal plan changes how much stability allocation you need, and how much you need in the G Fund changes whether a partial or full transfer makes sense.
Capital Area Planning Group is a Washington, DC advisory firm whose stated client focus is business executives, equity compensation, high-net-worth and ultra-high-net-worth individuals, and retirees. That DC and executive orientation is relevant here, because senior federal and quasi-federal careers tend to combine a TSP balance with deferred compensation and equity, and the sequencing question spans all three.
The honest limitation: no advisor can restore the age-55 exception once the money is in an IRA, and no allocation change guarantees a better outcome. What planning can do is make the decision reversible where it is reversible and deliberate where it is not.

Frequently Asked Questions
Should I roll my TSP into an IRA when I retire? It depends mostly on your age and your withdrawal timeline. If you separated at 55 or later and plan to draw before 59½, staying in the TSP preserves a penalty exception that does not follow the money to an IRA. If you are past 59½ and want broader investment options, a transfer is more likely to make sense.
Does the TSP age-55 rule apply after a rollover to an IRA? No. The exception applies to distributions from the plan, not from an IRA. Once the balance is in a traditional IRA, distributions before 59½ are generally subject to the 10% additional tax unless a separate IRA exception applies.
Can I move only part of my TSP to an IRA? Generally yes, and a partial transfer is often the practical answer. It lets you keep the G Fund allocation and the plan's low expense ratios while moving the portion you want managed elsewhere. Confirm the current partial-withdrawal and transfer rules with the plan before initiating.
Do Roth TSP accounts still have required minimum distributions? Not during the account owner's lifetime. SECURE 2.0 removed lifetime RMDs from designated Roth accounts in employer plans, including the Roth TSP, for taxable years beginning after December 31, 2023. Beneficiary distribution rules still apply after death.
