TSP Rollover — Leave It, Roll It,
or Do Both?
The Complete Decision Guide for Federal Employees Leaving Service
G Fund · Partial Rollover · Roth Conversion · Age 55 Rule · Beneficiary Planning
The TSP is one of the best retirement plans in existence — low costs, the unique G Fund, strong creditor protection. But it also has real limitations: no Roth conversions, rigid distribution options, limited investment menu. The question at retirement isn’t just “should I roll over?” It’s which funds to keep, which to move, when to convert, and how to use the TSP as a tax-planning tool rather than just an account to empty.

After Separation
Options (G/F/C/S/I/L)
When You Leave Federal Service, You Have Four Options for Your TSP
None of them is universally “right.” The best answer depends on your age at separation, how close you are to retirement, whether you need early access, your Roth conversion goals, and how much you value the G Fund. Here’s what each option actually means.
Option 1
Leave It in TSP
- ✅ G Fund access preserved
- ✅ 0.060% expense ratio
- ✅ Strong creditor protection
- ✅ Age 55 penalty-free access (if separated at 55+)
- ✅ No action required
- ❌ No Roth conversions inside TSP
- ❌ Limited distribution flexibility
- ❌ Only 6 investment options
- ❌ No new contributions unless you return to service
Best for: Retirees who value G Fund and simplicity, or who may need penalty-free access between 55–59½.
Option 2
Partial Rollover
- ✅ Keep G Fund in TSP
- ✅ Move C/S/I equity to IRA for Roth conversions
- ✅ Best of both worlds for most retirees
- ✅ Age 55 rule preserved on TSP portion
- ✅ IRA portion gets full investment flexibility
- ⚠️ Requires managing two accounts
- ⚠️ Rollover of traditional TSP to traditional IRA: tax-free if done directly
Best for: Most FERS retirees — keeps G Fund while unlocking Roth conversion flexibility on equity portion.
Option 3
Full Rollover to IRA
- ✅ Maximum investment flexibility
- ✅ Full Roth conversion ability
- ✅ Better beneficiary planning
- ✅ Easier partial withdrawals
- ✅ Can consolidate multiple accounts
- ❌ G Fund access permanently lost
- ❌ IRA expense ratios typically higher
- ❌ Age 55 rule lost (IRA penalty applies until 59½)
- ❌ Slightly less creditor protection than TSP
Best for: Retirees over 59½ who have no use for G Fund and want maximum Roth conversion and estate planning flexibility.
Option 4
Cash Out
- ❌ 20% mandatory federal withholding
- ❌ 10% early withdrawal penalty (under 59½, unless age 55 rule applies)
- ❌ Full amount taxable as ordinary income
- ❌ State income taxes also apply
- ❌ Could lose 30–50% to combined taxes/penalties
- ❌ Permanently loses tax-deferred growth
Almost never the right choice. If you need access to funds, the age 55 rule or a 72(t) SEPP arrangement may allow penalty-free access without cashing out entirely.
| Your Situation | Recommended Approach | Primary Reason |
|---|---|---|
| Retiring at 55–59, need income before 59½ | Keep TSP (at least partially) | Age 55 penalty-free access; rolling to IRA loses this |
| Over 59½, want Roth conversion flexibility | Full or partial IRA rollover | IRA enables gradual Roth conversions; TSP cannot convert internally |
| Want guaranteed stable return component | Keep G Fund allocation in TSP | G Fund is unique — no IRA equivalent exists |
| Have large pre-tax IRA, want backdoor Roth | Roll IRA INTO TSP, then do backdoor Roth | TSP accepts incoming IRA rollovers, clearing pro-rata rule |
| Concerned about estate/beneficiary planning | Roll to IRA | IRA offers per-stirpes, trust beneficiary options; TSP defaults to federal order |
| Maximize flexibility, over 59½, no G Fund needed | Full IRA rollover | Most investment options, easiest Roth conversion, best beneficiary planning |
The G Fund — Why It’s the Only Real Reason
to Keep Money in TSP After Retirement
The G Fund is the single most unique investment available to federal employees. It cannot be replicated outside the TSP. Before you roll every dollar out, understand what you’re giving up.
📋 What Makes the G Fund Unique
- Invests in special non-marketable U.S. Treasury securities issued only to the TSP
- Interest rate is set monthly at the weighted average yield of all outstanding Treasury notes and bonds with 4+ years to maturity — essentially long-term bond rates
- But principal is completely protected — you cannot lose money in the G Fund, ever
- No commercial money market, stable value, or bond fund offers this combination
- Liquidity: moves to other TSP funds instantly with no redemption fees
- Expense ratio: included in the 0.060% blended TSP rate
📊 G Fund vs. Private Alternatives (Approximate 2024)
| Option | Yield | Principal Risk |
|---|---|---|
| G Fund (TSP) | ~4.6% | None |
| Money Market Fund (IRA) | 4.5–5.0% | Minimal |
| Stable Value Fund (401k) | 3.0–4.0% | Minimal |
| Short-Term Treasury ETF | 4.5–5.2% | Low-Medium |
| Intermediate Bond Fund | 4.0–5.5% | Medium |
| Long-Term Treasury Fund | 4.5–5.0% | High |
The G Fund gets long-term Treasury yields with zero principal risk — no IRA equivalent exists. Rates approximate and subject to change.
🎯 The Partial Rollover G Fund Strategy
The most common smart approach for retirees who value the G Fund:
- Determine what percentage of your portfolio you want in stable/fixed income
- Leave that allocation in TSP in the G Fund
- Roll the remaining equity allocation (C, S, I Funds) to a Traditional IRA
- Use the IRA for gradual Roth conversions during the gap years before RMDs
- Result: G Fund preserved, equity gains a Roth conversion pathway, age 55 rule preserved on TSP portion
Example: $600K TSP. $200K in G Fund (keep in TSP). $400K in C/S/I (roll to IRA for Roth conversions). G Fund continues earning ~4.6% with zero risk.
TSP Fund Lineup — What Each Fund Is and Where It Can Go
| Fund | What It Tracks | IRA Equivalent? | Roll to IRA? |
|---|---|---|---|
| G Fund | Special Treasury securities — long-term yield, no principal risk | No equivalent | Keep in TSP |
| F Fund | Bloomberg U.S. Aggregate Bond Index | AGG / BND ETFs | Rollable — good IRA alternatives exist |
| C Fund | S&P 500 Index | SPY / VOO / IVV | Rollable — excellent IRA equivalents |
| S Fund | Dow Jones U.S. Completion Total Stock Market Index (small/mid cap) | VXF / SCHA | Rollable — good IRA equivalents |
| I Fund | MSCI EAFE Index (international developed markets) | EFA / VXUS | Rollable — good IRA equivalents |
| L Funds | Lifecycle target-date funds (blend of G, F, C, S, I) | Target date funds | Rollable — consider components individually |
Direct vs. Indirect Rollover — One Right Way, One Costly Trap
Direct Rollover (Trustee-to-Trustee)
How it works: You instruct TSP to transfer funds directly to your IRA custodian. The money never passes through your hands. The IRA custodian receives the funds directly from TSP.
- Zero federal withholding
- Zero taxes due at time of transfer (Traditional → Traditional)
- No 60-day deadline to worry about
- Full balance transfers intact
- No transaction limit concerns
✅ ALWAYS use a direct rollover. Request it explicitly: “direct rollover to IRA.” Do not accept a check made payable to yourself.
Indirect Rollover (Check to You)
How it works: TSP sends a check payable to you. By law, TSP must withhold 20% for federal income tax. You receive 80% of your balance.
- TSP withholds 20% automatically — you only receive 80%
- You have 60 days to deposit the full original amount into an IRA
- To avoid tax, you must replace the withheld 20% from other sources
- If you only deposit the 80% you received, the missing 20% is a taxable distribution
- If under 59½, the taxable amount also faces a 10% penalty (unless age 55 rule applies)
- Miss the 60-day deadline: entire amount becomes a taxable distribution
⚠️ If you receive a check from TSP made out to you, you are already in an indirect rollover. The 60-day clock is running. Act immediately.
📅 The Age 55 Separation Rule
Federal employees who separate from service in or after the year they turn 55 can take TSP distributions without the 10% early withdrawal penalty — even before age 59½. This applies to the TSP balance at that employer only.
Critical caveat: If you roll that TSP to a Traditional IRA, the age 55 exception does not transfer. The IRA imposes its own 10% penalty until age 59½. If you are between 55 and 59½ and may need these funds, leaving the balance in TSP (or taking a partial rollover) preserves your penalty-free access.
Special rule: Certain public safety employees (law enforcement, firefighters, air traffic controllers) qualify for penalty-free access if they separate at age 50+.
📋 TSP Distribution Options After Retirement
After separating from federal service, the TSP offers these distribution choices:
- Single payment: One lump sum (full or partial)
- Monthly payments: Fixed dollar amount or based on life expectancy (IRS table)
- Life annuity: Purchase through MetLife — typically poor value vs. private market annuities; no surrender charge, but no flexibility after purchase
- Combination: Mix of the above
- Leave in TSP: No distributions until age 73 RMDs begin
TSP annuity: convenient but rates are typically less competitive than private market annuities. Always compare the TSP annuity rate to an independent annuity quote before purchasing.
📋 TSP Beneficiary — Update It Now
Your TSP beneficiary designation is completely separate from your will, trust, and estate plan. It overrides everything else. The default distribution order if no designation is on file: (1) spouse, (2) children equally, (3) parents, (4) estate.
“My estate” as beneficiary — the single most common TSP planning error. It sends the balance through probate, eliminates the spousal rollover option, and forces immediate distribution and taxation. A spouse who receives TSP through a beneficiary designation can roll it to their own IRA, preserving tax deferral. A spouse who receives it through “the estate” cannot.
Action: Log into TSP.gov → My Profile → Beneficiaries. Verify your designation matches your estate plan. Review after every major life change.
Partial Rollover + TSP as IRA Consolidation Vehicle — Two Strategies Most Federal Employees Miss
Strategy 1: The Partial Rollover — Best of Both Worlds
Federal employees are not required to roll all-or-nothing. You can roll a specific dollar amount or specific fund balances to an IRA while retaining the rest in TSP.
Example: James, retiring FERS employee with $750K TSP
- $200K in G Fund → Keep in TSP. Earns ~4.6% with zero risk. James uses this as his stable income reserve.
- $550K in C/S/I Funds → Roll to Traditional IRA. James converts $50,000–$60,000/year to Roth during his gap years (ages 62–73). Converts at 12–22% federal bracket before RMDs begin.
- Result: $200K G Fund still compounding at guaranteed long-term rates. $550K in IRA being gradually converted to tax-free Roth. Both objectives achieved simultaneously.
Strategy 2: Roll IRAs INTO the TSP (Reverse Rollover)
Most people think about rolling TSP out. But the TSP also accepts incoming rollovers from Traditional IRAs — and this creates a powerful planning opportunity.
The Pro-Rata Problem: When doing a Backdoor Roth IRA, the IRS requires you to include all pre-tax IRA funds in the conversion calculation (pro-rata rule). If you have $100,000 in a traditional IRA and contribute $7,000 after-tax to a new IRA, then convert that $7,000, the IRS treats 93.5% of the conversion as taxable — not $0.
The fix — Roll pre-tax IRA into TSP:
- Roll the $100,000 traditional IRA into the TSP (TSP accepts it)
- Now you have $0 in traditional IRAs — pro-rata problem eliminated
- Make your $7,000 non-deductible IRA contribution
- Convert that $7,000 to Roth — 100% tax-free (no pro-rata basis)
- The $100K is preserved in TSP at 0.060% expense ratio with G Fund access
Only applies to Traditional IRA funds. Roth IRA funds cannot be rolled to TSP.
Roth TSP — What Changed With SECURE 2.0, and How to Use It
📋 Roth TSP Basics
- Contributions are after-tax — no deduction in the year contributed
- Growth and qualified distributions are tax-free
- Same contribution limits as Traditional TSP — not separate (combined $23,000 limit in 2024)
- Agency match is always deposited to the Traditional TSP side (pre-tax), even if you contribute to Roth TSP
- SECURE 2.0: As of 2024, Roth TSP is no longer subject to RMDs during the owner’s lifetime — eliminating a major prior disadvantage vs. Roth IRA
- Can be rolled to a Roth IRA upon separation — preserving tax-free status with no taxable event
🔄 Converting Traditional TSP to Roth
You cannot convert Traditional TSP funds to Roth TSP directly within the TSP. To Roth-convert traditional TSP funds:
- Roll Traditional TSP to a Traditional IRA (direct rollover)
- Gradually convert Traditional IRA funds to Roth IRA over the gap years
- Pay income tax on each year’s converted amount
- Result: tax-free Roth IRA with no future RMDs and no MAGI impact
Roth conversions must be funded with outside cash — don’t sell assets to pay the tax bill; use savings or a brokerage account. The converted amount must stay in Roth for 5 years for tax-free qualified distribution.
💡 Should You Contribute to Traditional or Roth TSP While Working?
The answer depends on your expected tax rate now vs. in retirement:
- High earner now, expect lower income in retirement: Traditional TSP (deduct now at high rate, pay later at lower rate)
- Moderate earner, pension will fill lower brackets: Roth TSP (contribute after-tax now at moderate rate; future pension + SS will fill lower brackets regardless)
- Young federal employee: Roth TSP — decades of tax-free compounding outweigh near-term deduction
- FERS near retirement, large TSP balance: Consider Roth TSP contributions to build tax-free bucket alongside planned Roth conversions
⚠️ The FERS Pension + TSP Income Stacking Problem
FERS retirees face a structural income stacking challenge: the pension provides a base of fully taxable income from day one. When TSP RMDs begin at age 73 on top of pension + Social Security, the combined income frequently pushes into the 22–24% federal bracket and potentially above IRMAA thresholds. Every dollar left in the Traditional TSP today is a future dollar that will be forced out as a taxable RMD — often at a higher rate than you’d pay on a voluntary conversion today.
This is why the gap years between FERS retirement and age 73 are the most valuable tax planning window most federal employees ever have. Strategic Roth conversions during that window — using the partial TSP rollover to access IRA conversion flexibility while keeping the G Fund — directly address this problem.

The Seven TSP Rollover Mistakes Federal Employees Make — and How to Avoid Every One
Mistake 1: Taking an Indirect Rollover
Requesting a check from TSP triggers mandatory 20% withholding. If you can’t replace the withheld amount within 60 days, it’s a permanent taxable distribution — plus a potential 10% penalty. Always request a direct rollover.
Mistake 2: Rolling Into a Surrender-Charge Annuity
Some advisors roll TSP into annuity products with 6–10% surrender charge schedules lasting 7–12 years. If you need the funds during that period — for healthcare, a home repair, an emergency — you pay the surrender charge. We always disclose surrender charge schedules before any recommendation.
Mistake 3: Rolling Over at 56 and Needing the Money at 57
Federal employees who separated at 55+ have penalty-free TSP access. If they roll to an IRA and then need distributions before 59½, the 10% penalty applies — a problem that didn’t exist before the rollover. If you may need funds between 55 and 59½, do not roll to an IRA first.
Mistake 4: Rolling the G Fund to an IRA When Rates Are Favorable
Rolling the G Fund to a money market, bond fund, or stable value fund in an IRA gives up a genuine structural advantage with no substitute. When the G Fund yield is competitive with other safe options, keeping it in TSP costs nothing — rolling it out costs you the guarantee. Partial rollover: move equity funds, keep G Fund.
Mistake 5: Outdated or “My Estate” Beneficiary
TSP assets pass by beneficiary designation, not by will. An outdated designation or one naming “my estate” bypasses the spousal IRA rollover, triggers probate, and may force immediate distribution to wrong people. Update your TSP beneficiary at TSP.gov today.
Mistake 6: Rolling to IRA Without a Roth Conversion Plan
Rolling TSP to a Traditional IRA “for more flexibility” and then leaving it untouched until RMDs forces the same tax problem — just in an IRA instead of TSP. The rollover is only valuable if it’s followed by a systematic Roth conversion strategy during the gap years. Have the plan before the rollover, not after.
Mistake 7: Converting a Large TSP in One Year
Rolling $400,000 of TSP to a Roth IRA in one year creates a $400,000 taxable event — pushing into the 32–37% bracket and triggering maximum IRMAA surcharges for 2 years. Gradual annual conversions over 8–12 years at 12–22% are nearly always far more efficient. The “all at once” Roth conversion is almost never the right choice.
