TSP Guide

Should you roll your TSP to an IRA?

The moment you retire, the financial industry will encourage you to roll your TSP into an IRA — and sometimes that’s genuinely the right move. But the TSP is in a league of its own on cost, it holds the one-of-a-kind G Fund, and it carries strong legal protections. Rolling out buys you a wider investment menu, charitable-giving options, and flexible withdrawals — at the price of higher fees and the loss of that G Fund. This isn’t a one-size decision; it’s a tradeoff you should make with eyes open. Here’s the honest case each way, the fee math that surprises people, and a calculator that shows what rolling really costs.

1. The decision at retirement

When you separate from federal service, your TSP doesn’t force you out — you can leave it right where it is, draw income from it, or move it to an IRA. The pitch to roll over is constant, and advisors who manage IRAs have an obvious interest in it. That doesn’t make rolling wrong; it just means you should weigh the trade yourself rather than accept the default.

The honest framing: the TSP is an exceptional accumulation vehicle and a very good distribution vehicle, but it’s deliberately simple. An IRA is more flexible and more expensive. Whether that trade favors you depends on what you actually need in retirement — and most of this guide is about making that comparison concrete.

2. The case for keeping the TSP

Four real advantages keep money in the TSP:

3. The case for rolling to an IRA

The IRA earns its higher cost with flexibility the TSP can’t match:

4. The fee gap

The single most underappreciated factor is cost, because small percentages compound into large dollars. The TSP’s ~0.05% versus a typical IRA fund line-up around 0.40% looks trivial — until you run it on a real balance over a real retirement:

$500,000 × 0.05% = $250/yr (TSP)  vs  $500,000 × 0.40% = $2,000/yr (IRA)

That’s a $1,750 difference every year, or roughly $17,500 over a decade — and that ignores the compounding drag on growth, which makes the real gap larger. None of this means “never roll”; it means the IRA’s added value — choice, QCDs, control — has to be worth more than this cost. The calculator next lets you test your own numbers.

5. What higher fees cost you

Enter your balance, an expected return, a time horizon, and the two expense ratios. The calculator grows the same money under each fee level and shows the gap — the true cost of paying for the IRA’s flexibility, assuming identical investments.

Both balances grow at your gross return minus the expense ratio; this isolates fees and assumes identical investments. The IRA’s real payoff — investment choice, QCDs, withdrawal control — isn’t captured here and may be worth the cost. Estimate only, not advice.

6. The G Fund question

If one feature single-handedly keeps money in the TSP, it’s the G Fund. It invests in special-issue government securities that pay interest tied to intermediate-term Treasury yields but can never lose principal value. That pairing — meaningful yield with zero market risk — doesn’t exist in the open market. You can buy Treasuries, CDs, or bond funds in an IRA, but bond funds fluctuate with rates and individual bonds tie up your money to maturity.

For a retiree who wants a stable, no-drama anchor for the conservative slice of their portfolio, the G Fund is genuinely irreplaceable. That’s exactly why the partial rollover is so popular: keep enough in the TSP to hold the G Fund, and roll the growth-and-flexibility portion to an IRA. You don’t have to choose all or nothing.

7. The 2026 in-plan conversion wrinkle

One classic reason to roll out has weakened. In the past, feds who wanted to convert traditional money to Roth had to roll to an IRA first. As of January 28, 2026, the TSP added an in-plan Roth conversion option — you can convert traditional TSP balances to Roth TSP directly inside the account, no rollout required.

Combined with the 2024 change that made Roth TSP exempt from lifetime RMDs, two of the historical “roll out to an IRA” motives — converting to Roth and escaping Roth RMDs — can now be handled inside the TSP. That doesn’t eliminate the IRA’s other advantages, but it does mean a Roth conversion goal alone is no longer an automatic reason to leave. Note that an in-plan conversion is still a taxable event in the year you do it, just like any conversion.

8. How to do it right

If you decide to roll — in full or in part — a few rules protect you. Always use a direct, trustee-to-trustee rollover; if a check is instead sent to you (an indirect rollover), the TSP withholds 20% for taxes, and you must replace that 20% from other funds within 60 days or it’s treated as a taxable distribution. Keep the tax character matched — traditional TSP to a traditional IRA, Roth TSP to a Roth IRA — so the move itself stays tax-free.

Remember that rolling over doesn’t change the underlying rules: the 10% early-withdrawal penalty still applies before 59½ (with exceptions), and RMDs still come due. For the step-by-step mechanics — forms, timing, and how partial transfers work — see TSP rollovers, and fold the decision into your broader withdrawal plan rather than treating it as a standalone move.

9. Frequently asked questions

Should I roll my TSP into an IRA when I retire?

There’s no universal answer — it depends on what you value most. Keep the TSP if you prize its rock-bottom fees, the unique G Fund, simplicity, and strong creditor protection. Roll to an IRA if you want a far wider investment menu, the ability to make qualified charitable distributions, more flexible withdrawals that let you choose which holdings to sell, or easier estate planning. Many retirees do neither extreme: they keep a portion in the TSP — often to retain the G Fund — and roll the rest to an IRA. The decision generally makes most sense once you’ve actually committed to retirement, since the TSP remains an excellent low-cost vehicle while you’re still working.

What is the G Fund and why does it matter for this decision?

The G Fund is a TSP investment with no equivalent anywhere outside the federal system. It holds special government securities that pay interest in line with intermediate-term Treasury rates but never lose principal value — a combination of stability and yield you can’t buy in an IRA. You can approximate parts of it with bond funds, CDs, or Treasuries, but none replicate its no-loss feature. For retirees who want a rock-solid, low-volatility anchor for part of their portfolio, the G Fund alone is often reason enough to keep at least some money in the TSP, even while rolling the rest elsewhere.

Can I make qualified charitable distributions from my TSP?

No — and this is a common reason to roll to an IRA. A qualified charitable distribution (QCD) lets someone age 70½ or older send money directly from a traditional IRA to charity, satisfying required minimum distributions without the amount counting as taxable income. The TSP does not offer QCDs, so any TSP withdrawal you give to charity is fully taxable to you first. If charitable giving is part of your retirement plan, rolling a portion of your traditional TSP into a traditional IRA opens the door to QCDs — a clean, tax-efficient way to give while reducing your taxable RMDs.

How much do higher IRA fees actually cost?

More than most people expect, because fees compound. The TSP’s expense ratios have run around 0.05% — about $5 a year per $10,000 invested. If you roll to an IRA holding funds that average, say, 0.40%, you’d pay roughly $40 per $10,000 instead. On a $500,000 balance, that’s about $250 a year in the TSP versus $2,000 in the IRA — a $1,750 annual difference, or $17,500 over a decade before counting lost growth. That gap is the price of the IRA’s flexibility, so it only makes sense to pay it if the IRA’s added value — investment choice, QCDs, withdrawal control — is worth more to you than the cost.

Do I have to roll over the whole TSP or none of it?

You can do a partial rollover. A common approach is to keep a portion in the TSP — frequently the slice you want in the G Fund — while rolling the rest into an IRA for broader investments or QCD access. Always use a direct, trustee-to-trustee rollover rather than having a check sent to you, since an indirect rollover triggers 20% mandatory withholding that you’d have to replace from other funds within 60 days to avoid taxes. And keep the tax character matched: traditional TSP to a traditional IRA, Roth TSP to a Roth IRA, so the move itself stays tax-free.
