TSP Rollover to IRA: 2026 Complete Guide for Federal Employees

Rolling your Thrift Savings Plan to an IRA isn't always the right move. Two things you cannot replicate elsewhere — the G Fund's unique yield-without-duration-risk and penalty-free distributions before age 59½ — disappear the moment you roll. This guide walks through the full decision, the traps specific to federal employees, and when rolling to an IRA actually makes sense.

Who has a TSP

The Thrift Savings Plan is available to:

• FERS (Federal Employees' Retirement System) employees: The majority of civilian federal employees hired after 1983. FERS employees receive automatic agency contributions (1% of salary) and matching contributions up to 5% of salary — agency matching vests after 3 years of service.
• CSRS (Civil Service Retirement System) employees: A legacy system for long-tenured employees hired before 1984. CSRS employees can contribute to TSP but receive no agency matching.
• Uniformed services members: Active duty and reserve members of all seven uniformed services (Army, Navy, Air Force, Marines, Coast Guard, Space Force, NOAA/PHS). Military members under the legacy High-3 retirement system and under the Blended Retirement System (BRS, enacted 2018) both have TSP access. BRS members receive DoD matching up to 5% of basic pay, similar to FERS civilian employees.

TSP balances can be rolled to an IRA after separation from service — retirement, resignation, reduction-in-force, or for military members, discharge or release from active duty. You generally cannot roll an active TSP to an IRA while still employed, with the exception of age-based in-service withdrawals once you reach 59½.

The case for keeping money in the TSP

The G Fund: a genuinely unique asset class

The G Fund (Government Securities Investment Fund) earns interest set monthly, based on the average yield of U.S. Treasury securities with 4 or more years to maturity — currently 4.375% (April 2026, per tsp.gov).¹ What makes it structurally unusual is what it doesn't expose you to:

• No credit risk: G Fund securities are issued by the U.S. government. No possibility of default.
• No duration risk: Unlike a bond fund, the G Fund doesn't fall in value when interest rates rise. Its price is always $1 per unit; only the yield changes.
• Long-term bond yields with short-term price stability. This combination doesn't exist in the open market. Money market funds earn short-term rates. Bond funds earn long-term rates but carry duration risk. The G Fund earns long-term rates with no principal volatility.

You cannot replicate the G Fund in a brokerage IRA. The closest proxies — Treasury money market funds, short-duration Treasury ETFs, I-bonds — each surrender one of those properties. If you're using the G Fund as a fixed-income anchor in your retirement allocation, rolling out of the TSP means giving up a structurally superior asset with no equivalent replacement.

That said: if your allocation is all-equities or you hold fixed income primarily in taxable accounts, the G Fund advantage is irrelevant to you specifically.

Ultra-low expense ratios

The TSP's total net expense ratio across all funds is approximately 0.05% — $5 per $10,000 invested annually.² This is among the lowest of any defined-contribution plan in existence. For comparison:

• Average 401(k) expense ratio (asset-weighted): 0.4–1.0%
• Typical retail index fund IRA: 0.03–0.20%
• Vanguard Total Stock Market (VTSAX): 0.04%; Fidelity ZERO (FZROX): 0.00%
• TSP C Fund (tracks S&P 500 index): included in 0.05% overall

If you're planning to invest a rolled IRA in low-cost index funds at Vanguard, Fidelity, or Schwab, the fee difference between TSP and IRA is minimal. But if you're drawn toward actively managed funds, annuity products, or advisory accounts that carry higher fees, keeping the TSP at 0.05% compounds to a meaningful advantage over 20+ years on a large balance.

Penalty-free withdrawals before age 59½

If you separate from federal service in the year you turn 55 or later (or at any age for public safety employees — federal law enforcement officers, firefighters, air traffic controllers — who separate at 50 or later), you can take distributions from the TSP in any amount at any time without the 10% early withdrawal penalty under IRC § 72(t)(2)(A)(v).³

This is the same Rule of 55 that applies to 401(k) and 403(b) plans. It disappears the moment you roll the TSP to an IRA. IRA distributions before 59½ are subject to the 10% penalty unless a SEPP arrangement (IRC § 72(t) substantially equal periodic payments) or another specific exception applies.

The partial-rollover strategy for bridge income: Consider keeping enough in TSP to fund your pre-59½ income needs, and rolling only the long-term portion that won't be touched before 59½. Most TSP separation withdrawals allow partial rollovers — you specify exactly how much transfers and how much stays.

Strong creditor protection

TSP assets are protected from creditors under federal statute (5 U.S.C. § 8346(a) for FERS participants; § 8301 for CSRS).⁴ This protection is essentially unlimited and operates outside of bankruptcy proceedings — unlike IRA protection, which is capped federally at approximately $1.7M in bankruptcy (11 U.S.C. § 522(n), indexed triennially) and is state-specific for non-bankruptcy creditor claims. For federal employees in high-liability positions, keeping a significant balance in TSP provides unambiguous federal-statute protection.

The case for rolling TSP to an IRA

Investment flexibility

The TSP offers five core index funds — G (government securities), F (bond index), C (S&P 500), S (small/mid-cap), I (international) — plus L Funds (target-date blends). That's the entire menu. There are no sector funds, no factor ETFs, no REITs, no individual bonds, no TIPS, no small-cap value, no international small-cap, no alternative assets.

For most long-term accumulators, the TSP's five-fund lineup is genuinely sufficient. But for investors with specific goals — adding value and small-cap factor tilts, holding TIPS for inflation protection, using individual bonds for liability matching, or implementing a more granular asset location strategy — a rollover IRA at a custodian with full market access provides meaningfully more control.

Roth conversion access

The TSP launched an in-plan Roth conversion feature in 2022, but it has operational limitations. Rolling traditional TSP balances to a traditional IRA opens full Roth conversion flexibility: bracket-targeting across multiple years, strategic conversion in low-income years (a gap year before Social Security, a sabbatical, the early years of FERS retirement before pension and Social Security kick in), IRMAA cliff management, and a longer conversion runway for RMD reduction planning.

See our Roth conversion after rollover guide for the full strategy, 2026 tax brackets, and IRMAA cliff analysis with a tax-cost calculator.

Beneficiary and estate planning flexibility

IRAs offer significantly more flexible beneficiary designations: per-stirpes or per-capita designation, multiple contingent tiers, trust beneficiaries with see-through trust planning, and custodian-specific tools for blended families or charitable intent. TSP beneficiary designations are more rigid and limited. For federal employees with complex estate plans, rolling to a well-chosen IRA custodian with full beneficiary-planning tools is often the right long-term move.

Consolidation and simplicity

Federal employees who've also held private-sector jobs may have old 401(k)s or 403(b)s from previous employers alongside their TSP. Rolling everything into one IRA simplifies management: one custodian, one statement, one asset allocation to maintain, one beneficiary designation to update. Over decades of retirement, the reduced administrative burden and reduced risk of overlooked accounts is a real quality-of-life benefit.

TSP-specific traps to avoid

Trap 1 — Outstanding TSP loan at separation (QPLO rules)

If you have an outstanding TSP loan when you separate from service, it doesn't automatically disappear. Under post-SECURE 2.0 rules:

• If you don't repay the outstanding balance, it becomes a Qualified Plan Loan Offset (QPLO) — a taxable distribution equal to the unpaid loan balance.
• Unlike the old 60-day rollover window, you have until the tax filing deadline including extensions for the year of separation to deposit personal funds into a traditional IRA equal to the QPLO amount, offsetting the taxable event.
• If you can't fund the offset from personal savings, you owe ordinary income tax on the QPLO amount — plus the 10% penalty if under 59½ (absent the Rule of 55 exception).

Trap 2 — Pro-rata problem for backdoor Roth users

If you make non-deductible IRA contributions as part of a backdoor Roth strategy, rolling pre-tax Traditional TSP balances into a Traditional IRA will trigger the pro-rata rule (IRC § 408(d)(2)) on all future Roth conversions. The IRS looks annually at your ratio of non-deductible (after-tax) IRA basis to your total traditional IRA balance. A $300,000 pre-tax TSP rollover into a Traditional IRA alongside $7,000 of non-deductible contributions means roughly 2.3% of any future Roth conversion is tax-free — the other 97.7% is taxed at ordinary income rates.

If you're running a backdoor Roth strategy, keep your pre-tax TSP balance in the TSP (or roll it to a future employer's plan that accepts rollovers in) rather than adding it to a Traditional IRA. See our pro-rata rule guide for the three strategies to neutralize this problem.

Trap 3 — Roth TSP rollover and the 5-year qualifying distribution rule

Rolling Roth TSP to a Roth IRA is not a taxable event — there's no income tax on moving Roth-to-Roth. But the 5-year qualifying distribution clock matters for whether earnings come out tax-free:

• The Roth IRA must have been open for 5 years (measured from the first year a Roth IRA contribution was made, not the rollover date) for earnings to be tax-free on qualified distributions.
• When you do a direct rollover from Roth TSP to Roth IRA, the TSP's own Roth clock generally carries over — the year you first made Roth TSP contributions counts as the start date for the Roth IRA 5-year test, provided the rollover is a direct transfer.
• If you don't yet have a Roth IRA, open one and make any contribution (even a minimal amount) as early as possible to start the 5-year clock — well before you need to take qualified distributions.

Trap 4 — TSP pro-rata withdrawal ordering

When you take a TSP withdrawal from an account that has both Traditional and Roth balances, the TSP distributes proportionally from each — you can't choose to draw only from the Traditional or only from the Roth side. A rollover IRA at a standard custodian gives you full control over which dollars come out when. If precise withdrawal-source control matters to your tax plan, this is a practical reason to roll.

SECURE 2.0 change: Roth TSP lifetime RMDs eliminated (effective 2024)

Starting January 1, 2024, Roth TSP balances are no longer subject to required minimum distributions during the original account holder's lifetime — under SECURE 2.0 § 325.⁵ This aligned the TSP Roth treatment with Roth IRAs, which have never required lifetime RMDs. Prior to 2024, one argument for rolling Roth TSP to a Roth IRA was RMD avoidance. That argument is now gone: Roth TSP balances can remain in the TSP indefinitely without forced distributions, removing one historical incentive to roll the Roth side out.

Partial rollover: the frequently overlooked option

You don't have to choose between rolling everything or keeping everything. The TSP allows partial rollovers — you specify exactly how much to transfer to an IRA and leave the remainder in TSP.

Common partial-rollover strategies:

• Keep bridge-income funds in TSP, roll long-term money to IRA. If retiring at 56–58, keep 3–6 years of expected pre-59½ distributions in TSP for penalty-free access, and roll only the balance you won't touch before 59½ to an IRA for investment flexibility and Roth conversion access.
• Keep G Fund allocation in TSP, roll equity portion to IRA. If you value the G Fund for your fixed-income anchor, keep that balance in TSP and roll the C/S/I Fund portion to a brokerage IRA where you have access to factor funds, REITs, TIPS, and more.
• Roll Traditional TSP to IRA for Roth conversions; keep Roth TSP in TSP. Since Roth TSP now has no lifetime RMDs, you may not need to roll the Roth portion. The Traditional TSP can come out to an IRA for systematic bracket-targeted Roth conversions over multiple years.

Step-by-step: how to execute the TSP rollover

1. Resolve outstanding TSP loans before separation. If you have a loan balance, decide whether to repay it in full or plan for the QPLO liquidity need. Don't discover this after the fact.
2. Open the destination IRA at your chosen custodian (Fidelity, Vanguard, Schwab are common). The account type must match: Traditional TSP → Traditional IRA; Roth TSP → Roth IRA. Rolling Roth TSP to a Traditional IRA is a conversion — a taxable event, not a rollover.
3. Request a direct rollover from tsp.gov. Log in, go to Withdrawals, and select "Transfer" to an eligible retirement plan. Specify the receiving custodian and account number. Always choose direct (trustee-to-trustee) — if a check is cut to you instead, 20% federal withholding is mandatory and you'll have 60 days to deposit the full gross amount or face a taxable distribution. See our 60-day rollover guide for the full trap mechanics.
4. Confirm receipt at your IRA custodian. Allow 5–10 business days. Verify the correct amount arrived and is classified correctly (Traditional vs Roth).
5. Update beneficiary designations immediately. Your TSP beneficiary designation does not carry over to your IRA. Name beneficiaries on the receiving IRA right away — don't let the default (usually your estate) stand. See our IRA beneficiary designations guide for the full rules and the cost of letting the estate inherit.
