Military TSP to IRA Rollover: A Veteran's Complete Guide for 2026

← Back to All Guides

When I transitioned out of the military after 20 years of service, the briefing I received on my finances was cursory at best. They handed me a checklist, shook my hand, and wished me luck. I had a significant balance in my Thrift Savings Plan (TSP), a pension I didn't fully understand how to tax-optimize, and a vague notion that I should "probably do something" with my retirement accounts.

That "something" usually involves a decision that will affect your wealth for decades: Should you keep your money in the TSP or execute a Military TSP rollover to an IRA?

For most veterans, the default advice is often "leave it in the TSP because fees are low." While the TSP's G Fund offers unique safety and expense ratios are indeed low (approximately 0.048%), fees are no longer the only — or even the most important — factor in veteran wealth management. The passing of the SECURE Act 2.0 and changes to inheritance laws have fundamentally altered the calculus for military families.

This guide is written for my fellow veterans who want to move beyond "default settings" and take command of their financial legacy. We will cover the tactical execution of a TSP to IRA conversion, sophisticated TSP Roth conversion strategies, and how to protect your hard-earned benefits from unnecessary taxation.

1. Understanding the Thrift Savings Plan (TSP)

The Thrift Savings Plan is the federal government's version of a 401(k). It is a defined contribution plan that has served as the bedrock of military retirement savings, especially with the advent of the Blended Retirement System (BRS).

The Core 5 Funds

Unlike civilian 401(k)s that may offer dozens of choices, the TSP keeps it simple:

• G Fund (Government Securities): The only investment in the world guaranteed to never lose principal while earning interest equal to long-term Treasuries.
• F Fund (Fixed Income): Tracks the Bloomberg U.S. Aggregate Bond Index.
• C Fund (Common Stock): Tracks the S&P 500 Index (large U.S. companies).
• S Fund (Small Cap): Tracks the Dow Jones U.S. Completion Total Stock Market Index.
• I Fund (International): Tracks the MSCI EAFE Index (international developed markets).

2026 Limits and Matches

For 2026, the elective deferral limit has risen to $23,500. If you are age 50 or older, you can contribute an additional $7,500 in catch-up contributions. For those under the Blended Retirement System (BRS), the DoD matches up to 5% of your base pay — free money you should never leave on the table while active.

2. When to Rollover: Separation, Retirement, or Wait?

The timing of your TSP to IRA conversion is critical. You generally have three windows:

Separation Before Retirement

If you separate before 20 years, you keep your TSP but lose the ability to contribute (unless you join federal civil service). A rollover here is often advantageous to consolidate accounts and gain investment flexibility.

Military Retirement (20+ Years)

Retiring with a pension changes your risk profile. You now have a "floor" of income. This is often the ideal time to evaluate a rollover to execute Roth conversion strategies during your "gap years" (the years between military retirement and Social Security/RMD age).

The Age 59½ and Age 73 Milestones

Once you reach age 59½, you can withdraw penalty-free. However, at age 73, Required Minimum Distributions (RMDs) kick in. The TSP has historically been rigid with withdrawal options compared to IRAs. RMDs from a Traditional TSP are fully taxable and can cause a "tax torpedo" when combined with your military pension and Social Security.

3. TSP vs. IRA: Key Differences and Advantages

Why move money out of a low-cost plan? Because cost is not the only metric of value. Control, tax flexibility, and estate planning often outweigh a few basis points in expense ratios.

Feature	Thrift Savings Plan (TSP)	Individual Retirement Account (IRA)
Investment Options	Limited to 5 core funds + Lifecycle funds.	Unlimited: Stocks, bonds, ETFs, options, real estate, private equity.
Withdrawal Flexibility	Rigid proportional withdrawals (must take from Trad and Roth pro-rata).	Total flexibility. Pick which tax bucket to draw from.
Roth Conversions	Not allowed within the plan.	Allowed and critical. Convert precise amounts annually.
Fees	Very Low (~0.048%).	Varies. ETFs as low as 0.03%; advisory fees add ~1%.
Beneficiary Protection	Limited "Trust" options. Rigid payout rules.	Highly flexible. Can use "See-Through Trusts" to protect heirs.
Public Safety Exception	Yes (Age 50 rule applies to some).	No (Age 50 rule generally does not apply to IRAs).

4. The Roth Conversion Ladder Strategy

This is the primary reason high-net-worth veterans execute a military TSP rollover. The strategy involves systematically moving money from your Traditional (Pre-Tax) IRA to a Roth (Tax-Free) IRA over a series of years.

Why the "Gap Years" Matter

Most veterans retire in their 40s or 50s. You have a military pension, but you likely haven't started Social Security (age 62-70) or RMDs (age 73). This creates a "tax valley" — a period where your taxable income is lower than it will be later in life.

The Strategy

1. Rollover: Move Traditional TSP funds to a Traditional IRA.
2. Convert: Every year, convert enough Traditional IRA funds to Roth IRA funds to "fill up" your current tax bracket (e.g., the 22% or 24% bracket).
3. Pay Tax Now: You pay taxes on the conversion amount now, while rates are historically low and your income is in the "valley."
4. Grow Tax-Free: That money grows tax-free forever.
5. Withdraw Tax-Free: Distributions from Roth IRAs do not count as provisional income, meaning they won't trigger higher taxes on your Social Security later.

You cannot do this inside the TSP. You must move the funds to an IRA to execute this surgical tax maneuver. For a deep dive, see our Strategy Report 07: The TSP Legacy Protection Plan.

5. The SECURE Act 10-Year Rule: Protecting Your Inheritance

The SECURE Act of 2019 eliminated the "Stretch IRA," which used to allow your children to inherit your retirement account and stretch distributions over their entire lifetime.

The New Reality: The 10-Year Rule

If you pass away and leave a Traditional TSP or IRA to a non-spouse beneficiary (like your children), they must empty the entire account within 10 years.

The Tax Bomb Scenario

Imagine you leave a $1,000,000 Traditional TSP to your daughter. She is 45 years old, in her peak earning years. She must withdraw that $1 million over 10 years, adding roughly $100,000 on top of her existing salary every year. This could push her into the highest tax bracket (37% Federal + State), causing nearly 50% of your life savings to vanish in taxes.

The Solution: If you convert that money to a Roth IRA before you die (using the ladder strategy above), she still has to empty the account in 10 years — but every penny she withdraws is 100% tax-free. You pay the tax toll at a discount today so she doesn't get crushed by it tomorrow.

6. Coordination with Military Pension and VA Disability

Veterans have a unique income trifecta that civilians don't:

1. Military Pension: Taxable at Federal level; varies by state.
2. VA Disability: 100% Tax-Free.
3. TSP/Investments: Taxable (Traditional) or Tax-Free (Roth).

The VA Disability Advantage

Because VA Disability is tax-free, it does not clutter your tax brackets. This allows you to convert more of your Traditional TSP to Roth without jumping into a higher bracket. A civilian with $60k income has $60k taxable. A veteran with $60k income might only have $30k taxable if half is VA Disability. This gives you "headroom" in lower tax brackets to move money cheaply.

7. College Planning for Military Families: FAFSA Strategies

Money inside your TSP or IRA is generally invisible to the FAFSA financial aid formula.

However, money you withdraw from the TSP to pay for living expenses counts as income, which hurts financial aid eligibility. By planning your rollovers and withdrawals carefully — perhaps delaying large distributions until your child's sophomore year of college — you can maximize financial aid.

Coordinating your TSP strategy with GI Bill usage is a niche area of veteran wealth management that generalist advisors often miss. Learn more in Strategy Report 08: The "Invisible" College Fund.

8. Non-Citizen Spouse Estate Planning

Many veterans married spouses from allied nations during overseas tours (Germany, Korea, Japan, UK). If your spouse is not a U.S. citizen, the standard "unlimited marital deduction" does not apply.

If you pass away with a large TSP balance, your non-citizen spouse cannot simply roll it over into their name tax-free in the same way a citizen spouse can. Without a Qualified Domestic Trust (QDOT) or specialized planning, your estate could face immediate taxation upon your death. See Strategy Report 09: The Sovereign Spouse Safety Plan.

9. Step-by-Step TSP Rollover Process

Executing a TSP to IRA conversion requires precision. One wrong checkbox can trigger a massive tax bill.

Step 1: Open Your Destination IRA

You cannot roll over to "yourself." You must open a Traditional IRA (and/or Roth IRA) at a custodian (e.g., Charles Schwab, Fidelity, or through Sirmium Capital).

Step 2: Log into TSP.gov

Use the "Rollovers and Distributions" tool. You will need the account number and "letter of acceptance" details from your new IRA custodian.

Step 3: Choose "Direct Rollover"

Crucial: Instruct the TSP to send the funds directly to the new financial institution. Do not have the check made payable to you.

Step 4: The 60-Day Rule

If the TSP mails the check to you (payable to the custodian), you must deposit it within 60 days. If you miss this window, the IRS treats the entire balance as a taxable distribution + 10% penalty (if under 59½).

Step 5: Invest

Once the funds arrive in your IRA, they will sit in cash. You must affirmatively invest them. This is the time to build a portfolio that complements your military pension — likely one with more growth potential than the G Fund.

10. Common Mistakes and How to Avoid Them

• Mistake #2: Rolling Roth TSP to Traditional IRA. This turns tax-free money back into taxable money. You must roll Roth TSP to Roth IRA, and Traditional TSP to Traditional IRA.
• Mistake #3: Forgetting NUA (Net Unrealized Appreciation). This rarely applies to TSP since it doesn't hold individual company stock, but is relevant if you rolled civilian 401(k)s into your TSP.
• Mistake #4: Ignoring State Taxes. Some states (like NY) exempt military pensions and federal TSP distributions from state tax. Moving to an IRA might change that tax treatment depending on state law.

11. FAQ

Can I rollover my TSP while still in service?

Generally, no. You can only do an "in-service withdrawal" if you are age 59½ or older, or for financial hardship. Most veterans must wait until they separate or retire.

What's the difference between Traditional and Roth IRA?

Traditional IRA is pre-tax (tax deduction now, pay tax later). Roth IRA is post-tax (pay tax now, tax-free forever). Given that tax rates are historically low and likely to rise, we heavily favor Roth strategies for veterans.

Do I pay taxes on a TSP to IRA rollover?

No, provided you roll Traditional to Traditional and Roth to Roth. Taxes are only triggered if you convert Traditional to Roth, or if you withdraw the money.

Can I roll my TSP to a 401(k) instead of an IRA?

Yes, if your new civilian employer accepts rollovers. However, you generally face the same limitations as the TSP.

What happens to my TSP loan if I separate?

You must repay it, usually within 90 days. If you don't, the outstanding balance is treated as a taxable distribution, subject to income tax and penalties.

Conclusion: The Mission Continues

Your military service is over, but your mission to protect your family's future has just begun. The TSP served you well during the accumulation phase of your career, offering low costs and simplicity. But in the distribution and legacy phase, flexibility and tax control become the priority.
