TSP to IRA rollover: what you gain and lose
A TSP to IRA rollover moves your balance to an account you control more freely. You gain investment choice and lose things the TSP gives you for nothing, including very low costs and a penalty exception that matters most to anyone retiring in their fifties.

What is a TSP to IRA rollover?
It is moving money out of the TSP into an account you own directly, and there are two ways to do it. A direct rollover sends the money straight to the receiving account. A traditional balance moved this way to a traditional IRA is not taxed in the current year, and nothing is withheld.
An indirect rollover pays you first, and that changes everything. Because the payment goes to you rather than to another plan, the TSP must withhold 20 percent for federal income tax.
The TSP's own example shows why that hurts. On a $10,000 distribution, $2,000 is withheld and $8,000 reaches you. To roll the whole $10,000 you have to find the missing $2,000 from your own savings. Figures are the TSP's illustration; see our assumptions for the values our calculator uses.
Then the clock runs. Anything not rolled over within 60 days is taxed, and it may carry the 10 percent early withdrawal penalty if you are under 59½. A direct rollover avoids the withholding and the deadline together.
What is the difference between a direct and indirect rollover?
A direct rollover moves the money straight to the receiving account, untaxed and with nothing withheld. An indirect rollover pays you first, so the TSP must withhold 20 percent. You then have 60 days to deposit the full original amount, replacing the withheld portion from your own funds.
Where can I move my traditional TSP balance?
To a traditional IRA, an eligible employer plan, a SIMPLE IRA, or a Roth IRA. The first two keep the money tax deferred. Moving a traditional balance to a Roth IRA is a conversion, so the full amount is taxable in the year you do it.
Is a traditional-to-Roth rollover taxed?
Yes, in full, in the current year. The trap is that no income tax is withheld at the time of the rollover, so nothing is set aside for the bill. The TSP notes you may need to pay estimated taxes to avoid falling short during the year.
The penalty exception you leave behind
This is the fact most likely to cost a federal retiree real money, and it is easy to miss. The TSP says the 10 percent additional tax generally does not apply to payments made after you separate from service during or after the year you reach age 55.
That exception belongs to the plan, not to you. The IRS is explicit that the exceptions in this group apply to distributions from a qualified plan other than an IRA, and the age-55 separation exception sits in that list.
So the money changes character when it moves. Roll a balance into an IRA at 56 and withdrawals from it are governed by the IRA rules, where 59½ is the threshold rather than 55.
Public-safety retirees have even more to lose. Their version of the exception reaches back to the year they turn 50, or to 25 years of service under the TSP. That is a far longer stretch of penalty-free access to give up.
Does the age-55 rule follow my money into an IRA?
No. The exception applies to payments from a qualified employer plan such as the TSP, not to IRAs. If you separate at 55 or later and roll your balance to an IRA, withdrawals from that IRA are subject to the ordinary 59½ threshold instead. Retiring in your fifties is exactly when this matters most.
Does this affect public safety retirees differently?
Yes, and more sharply. Their exception applies to payments after separating in or after the year they reach 50, or with 25 years of service under the TSP. Someone who retires at 50 and rolls everything to an IRA can face nearly a decade without penalty-free access.
What else you give up by leaving
The G Fund has no equivalent outside the plan. It is a government-backed fund available only to TSP participants, and no IRA offers the same thing, which matters most to anyone who uses it as their stability anchor.
Cost is the other thing you cannot buy back. The TSP argues its own case here, noting that low fund fees can add up to many tens of thousands of dollars over a long horizon. It makes that point even about its own mutual fund window.
You also leave the TSP's own withdrawal machinery behind, including its life annuity option. TSP withdrawal strategies covers what is available while the money stays.
None of this makes an IRA wrong. It means the things the TSP gives you for free are the things you should be sure you do not need.
Can I replace the G Fund in an IRA?
Not exactly. The G Fund is available only inside the TSP, and its combination of government backing with no market risk to principal is not something an IRA can reproduce. Short-term Treasury or money-market holdings are the usual substitutes, and they behave differently.
Are IRA fees really higher?
Not always, since some IRA providers offer very low-cost index funds. The TSP's point is about the cumulative effect over decades rather than any single comparison. If you move money, comparing total costs rather than headline fees is the check worth doing.
What a rollover actually buys you
Choice is the honest headline. An IRA reaches the whole market rather than five core funds and a set of lifecycle funds, which matters if you want something specific the TSP does not carry.
Consolidation is the practical one. Someone with a TSP, an old employer plan, and two IRAs has four statements and four beneficiary forms, and combining them reduces the chance something is missed later.
A Roth IRA adds one thing the TSP cannot. There are no required distributions during the owner's lifetime, so money can stay invested indefinitely rather than being drawn down on a schedule.
Estate flexibility is the quieter gain. IRAs generally offer more options for how beneficiaries take distributions than an employer plan does, which is worth weighing if leaving the balance to someone is part of the plan.
Why do people roll their TSP to an IRA?
Usually for investment choice, to consolidate scattered accounts, or for more flexible beneficiary options. Some also want a Roth IRA specifically, since it has no required distributions during the owner's lifetime. Each of those is a real benefit, and each has to be weighed against what the TSP provides at no extra cost.
Can I roll over only part of my TSP?
Yes, and it is the option people forget. A partial rollover lets you move the portion you want more control over while leaving the rest in the TSP, which keeps the low costs and the G Fund available. It also keeps the plan-based penalty exception attached to what remains.
What changes about required distributions?
The start age is the same wherever the money sits, and it depends on your birth year. SECURE 2.0 sets it at 73 for those born from 1951 through 1959, and 75 for those born in 1960 or later, for TSP balances and traditional IRAs alike.
What changed recently is which balances count. Roth balances in the TSP are no longer subject to required distributions during your lifetime, so the calculation now covers only your traditional money.
That removes what used to be a common reason to roll a Roth TSP into a Roth IRA. The RMD difference between them has largely closed, though a Roth IRA still has no lifetime distribution requirement at all.
The penalty for missing one has eased too. The excise tax on an RMD you fail to take fell from 50 percent to 25 percent, and to 10 percent if you correct it within two years.
Do I avoid RMDs by rolling my TSP to an IRA?
Not for traditional money, since traditional IRAs have required distributions on the same schedule. A Roth IRA has none during the owner's lifetime. That was once a strong reason to move a Roth TSP balance, but Roth TSP balances are no longer subject to lifetime RMDs either.
When do required distributions start?
It depends on when you were born: 73 if you were born from 1951 through 1959, and 75 if you were born in 1960 or later. The age applies to your traditional balance whether it sits in the TSP or a traditional IRA. Missing one carries an excise tax of 25 percent of the shortfall, reduced to 10 percent if you correct it within two years.
How to weigh staying against rolling
The decision usually turns on two questions rather than a long list. Do you need something the TSP does not offer, and will you need penalty-free access before 59½?
A reader who answers no to both has little to gain from moving. A reader who answers yes to the first and no to the second has a genuine case, and a partial rollover often serves them better than moving everything.
Timing matters more than people expect. Rolling after 59½ removes the penalty question entirely, so the same decision can be straightforward at 60 and expensive at 56.
We describe the trade rather than name an answer, because it depends on your age, your holdings, and what you would actually buy. To see how your TSP fits the rest of your plan, run your free readiness score.
Staying versus rolling
| Stay in the TSP | Roll to an IRA | |
|---|---|---|
| Investment choice | Five core funds plus L funds | The whole market |
| Cost | Deliberately low | Depends on provider and funds |
| Penalty-free at 55 after separating | Yes | No, 59½ applies |
Should I roll my TSP into an IRA?
That depends on what you need and when you need it, so we lay out the trade rather than recommend. The two questions that decide most cases are whether you want an investment the TSP does not offer, and whether you will need money before 59½. A partial rollover is often the answer when only the first is true.
Can I change my mind after rolling over?
Not easily. Money moved out of the TSP cannot simply be returned, and the plan-based penalty exception does not come back with it. That asymmetry is the reason to be deliberate about the timing and the amount rather than moving the whole balance by default.
