TSP Rollover Guide: Should You Move Your TSP to an IRA After Retirement?

Retiring (or separating) brings a big question: TSP rollover to IRA — should you do it, or leave your money in the Thrift Savings Plan? Many federal employees and military members feel stuck here. You hear “IRAs have more choices,” but you also hear “TSP is cheaper and safer.” Both can be true.

Here’s the good news: you don’t have to guess. You can compare costs, rules, and taxes with a few simple checks. And if you want the fastest way to see your own numbers (pay, pension, TSP, taxes, and timing), the free calculator at https://www.ismyjobworthit.com can save you a ton of time. It helps you model “keep TSP” vs “roll to IRA” using your situation.

Let’s break it down in plain English.

Background: What a TSP transfer after retirement really means

A rollover is moving retirement money from one account to another without paying taxes right now. A TSP transfer after retirement usually means moving money from your TSP to:

a Traditional IRA (tax-deferred, like Traditional TSP), or
a Roth IRA (after-tax, like Roth TSP, but with different rules)

The key idea: a rollover is not the same as a withdrawal. If you do it right, it’s not taxable in the year you move it.

TSP basics (quick refresher)

TSP is the federal government’s retirement savings plan. It works like a 401(k). You can invest in:

G Fund (special government securities, very stable)
F Fund (bonds)
C Fund (large U.S. stocks)
S Fund (small/mid U.S. stocks)
I Fund (international stocks)
Lifecycle (L) Funds (mix that changes over time)

TSP is known for low costs and simple choices. You can read the official rules and options at TSP.gov and see withdrawal details at TSP withdrawal options.

IRA basics (quick refresher)

An IRA is an account you open at a brokerage (like Vanguard, Fidelity, Schwab, etc.). IRAs often offer:

more investment choices (stocks, bonds, ETFs, mutual funds)
more flexible beneficiary and estate options (sometimes)
more control over withdrawals (depends on the firm)

But IRAs can also come with higher fees if you pick expensive funds or pay an advisor.

The tax rule that matters most

Traditional TSP → Traditional IRA is usually a non-taxable rollover.
Roth TSP → Roth IRA is usually a non-taxable rollover.

If you mix pre-tax and after-tax money, you must be careful. The IRS explains after-tax rollovers here: IRS rollover of after-tax amounts.

TSP vs IRA retirement: When keeping TSP is the smart move

If you’re asking “should I roll over TSP,” start by checking what you’d lose by leaving.

1) The G Fund is a big deal

The G Fund is unique. It’s backed by the U.S. government and has no risk of losing money from interest rate changes like regular bond funds can. Many retirees use it as the “safe” part of their portfolio.

If you roll your TSP to an IRA, you cannot buy the G Fund in an IRA. You can buy bond funds, CDs, or Treasuries, but they are not the same.

2) TSP costs are often lower (but not always)

TSP expense ratios have been very low for years (often around 0.05% or less, though it can change). That means about $5 per year per $10,000 invested.

Example with real math:

You have $500,000 invested.
TSP cost at 0.05% = 0.0005 × 500,000 = $250 per year.
An IRA invested in funds averaging 0.40% = 0.004 × 500,000 = $2,000 per year.

That’s a $1,750 per year difference. Over 10 years, that’s $17,500 (not counting growth). Fees matter.

3) TSP has strong creditor protection

In plain terms: retirement accounts can have different protections if you get sued or go through bankruptcy. TSP has strong federal protections. IRAs also have protections, but they can vary by state and situation.

This is not a reason alone to keep TSP, but it’s a “don’t ignore it” factor.

4) You can still do simple withdrawals in retirement

TSP has improved its withdrawal options. You can take:

installment payments,
partial withdrawals,
and change your amounts.

Before you roll over, review the current rules at TSP.gov withdrawal options.

5) You might want to keep the door open for a later move

You don’t have to decide once and forever. Many retirees keep TSP for a few years, then roll over later when they want different investments or a different withdrawal setup.

If you want to compare the long-term impact on your own retirement income, the easiest method is to run your numbers through https://www.ismyjobworthit.com and test “keep TSP” vs “TSP rollover to IRA” side by side.

TSP rollover to IRA: When moving it can make sense (and when it can backfire)

Rolling to an IRA can be great. It can also be a costly mistake if you don’t know why you’re doing it.

1) You want more investment choices

TSP is simple by design. An IRA can offer:

Treasury ladders
dividend ETFs
municipal bonds (if you understand taxes)
more international exposure
factor funds (value, small cap, etc.)

If you’re a hands-on investor, this can be a real plus.

But here’s the catch: more choices can lead to more mistakes. People chase hot funds, overtrade, or pay high fees without noticing.

2) You want more flexible withdrawal “tools”

IRAs usually let you:

choose which fund to sell (more control over taxes and risk)
set up custom withdrawal plans

TSP is improving, but it’s still more limited than many brokerages.

3) You’re dealing with old accounts and want to simplify

Many people retire with:

TSP
an old 401(k)
a spouse’s plan
maybe an IRA already

Sometimes rolling TSP into an IRA makes your life easier. Fewer accounts. One login. One plan.

4) You’re working with an advisor (carefully)

Some retirees want a professional to manage investments. That can be fine.

Watch the fee math. If an advisor charges 1% per year, that’s:

1% of $600,000 = $6,000 every year

That’s on top of fund fees. A good advisor may earn it, but you should know the price.

5) One big “backfire” risk: giving up the G Fund and low fees

If you roll over and then end up in:

high-fee mutual funds (1%+)
variable annuities (often expensive and complex)
frequent trading costs

…your retirement can take a hit.

To sanity-check your plan, use trusted info sources like TSP.gov and also read practical coverage from places federal folks actually follow, like FedWeek, GovExec, and Federal Times. (They’re not official, but they track real-world changes and common issues.)

Practical Examples: Real “should I roll over TSP” scenarios with numbers

These examples use simple math to show what changes. Your real answer depends on taxes, age, and goals. (Again, https://www.ismyjobworthit.com is a quick way to model your personal results.)

Example 1: FERS retiree, age 62, $450,000 TSP, wants low stress

TSP balance: $450,000
Plan: 40% G, 40% C, 20% F
Estimated average fee:
- TSP at 0.05%: 0.0005 × 450,000 = $225/year

If they roll to an IRA and pick funds averaging 0.30%:

IRA fee: 0.003 × 450,000 = $1,350/year

Difference: $1,125/year

If they don’t need special investments, keeping TSP may be the better deal. They also keep the G Fund.

Example 2: Retired O-4, age 45, $220,000 TSP, wants more growth options

This person has a military pension and is not touching TSP for 15+ years.

TSP: $220,000
They want more small-cap and international choices than TSP offers.

If they roll to an IRA and build a low-cost ETF mix at 0.07%:

IRA fee: 0.0007 × 220,000 = $154/year

That’s close to TSP costs. For them, the IRA’s extra choices might be worth it. But they give up the G Fund (which they may not care about at age 45).

Example 3: E-5 separating at 10 years, $60,000 TSP, needs access soon

Let’s say an E-5 is leaving active duty and may need money for a home down payment in 2 years.

Important: A rollover does not avoid early withdrawal rules. If they pull money out before age 59½, they may face taxes and a 10% penalty (with some exceptions).

If they take a $20,000 taxable withdrawal from Traditional TSP:

Assume 22% federal tax bracket: 0.22 × 20,000 = $4,400
Early penalty (10%): 0.10 × 20,000 = $2,000
Total potential hit: $6,400
Net received: $13,600 (before state tax)

Rolling to an IRA doesn’t fix that. The better move might be planning cash needs before separating, or leaving retirement money alone.

Example 4: Mixed Traditional + Roth TSP, wants Roth IRA for easier long-term planning

Say you have:

Traditional TSP: $300,000
Roth TSP: $80,000

You can roll them to:

Traditional IRA: $300,000
Roth IRA: $80,000

That can make future planning easier, especially if you want Roth money in a Roth IRA for estate planning or investment choices.

But you must do it correctly. If you accidentally roll Roth money into a Traditional IRA, you create a mess. Use IRS guidance: IRS.gov and confirm the receiving account types match.

Common mistakes and misconceptions (that cost real money)

Mistake 1: “An IRA is always better.” Not true. TSP’s low fees and the G Fund are hard to beat.
Mistake 2: “A rollover is tax-free no matter what.” It’s only non-taxable if you do a proper rollover to the right account type.
Mistake 3: “I have to move my TSP when I retire.” You usually don’t. Most retirees can keep TSP.
Mistake 4: Paying high advisor or fund fees without noticing. A 1% fee on $700,000 is $7,000 per year.
Mistake 5: Ignoring required minimum distributions (RMDs). RMD rules can change over time. Always confirm current rules on IRS.gov and TSP.gov.

Step-by-step: How to do a TSP rollover to IRA (the safe way)

You’ll want a “direct rollover.” That means the money moves from TSP to the IRA without being paid to you.

Step 1: Decide what you’re moving (all or part)

Ask:

Do I want to keep some money in TSP for the G Fund?
Am I rolling Traditional, Roth, or both?

Many people do a split: keep a chunk in TSP, roll the rest.

Step 2: Open the right IRA account(s)

Traditional TSP → Traditional IRA
Roth TSP → Roth IRA

If you need both, open both.

Step 3: Pick the receiving firm carefully

Look for:

low-cost index funds or ETFs
no account fees (or very low)
strong customer support
easy beneficiary setup

Step 4: Start the rollover from TSP (not from the IRA)

Go to TSP.gov and follow the rollover/transfer process. TSP will guide you through forms and options.

Step 5: Avoid “60-day rollover” risk if you can

A “60-day rollover” is when the check is made out to you and you must deposit it within 60 days. If you miss the deadline, it can become taxable.

A direct rollover is safer.

Step 6: Confirm the deposit and invest the money

Once it lands in the IRA:

confirm amounts match
invest based on your plan (don’t leave it in cash by accident)

Step 7: Keep records for taxes

You’ll get tax forms (like a 1099-R). Keep them with your tax file. If you rolled after-tax amounts, read the IRS guidance: rollover of after-tax amounts.

Key takeaways / Bottom Line: TSP vs IRA retirement

If you’re deciding on a TSP transfer after retirement, focus on three things: fees, the G Fund, and withdrawal flexibility.

Keep TSP if you value low costs, simplicity, and the G Fund.
Consider a TSP rollover to IRA if you need more investment choices, want a different withdrawal setup, or are consolidating accounts.
You can also do a partial rollover and keep the best of both.
