Veterans: TSP Myths Costing You Millions by 2026

So much misinformation swirls around the financial futures of our servicemembers and veterans, especially when it comes to navigating military retirement plans (Thrift Savings Plan, veterans). It’s an area rife with complexity, where a single misunderstood detail can cost you hundreds of thousands over a lifetime. Don’t let common myths derail your financial security; understanding the truth is your strongest defense.

It’s astonishing how many veterans I speak with, even those who’ve served for decades, harbor fundamental misunderstandings about their most significant retirement asset: the Thrift Savings Plan. As a financial planner specializing in military transitions, I’ve seen these myths cost people dearly. We’re going to bust some of the biggest ones right now, because your financial future is too important for guesswork.

Myth 1: The TSP is only for active-duty military personnel.

This is a pervasive misconception, and it’s flat-out wrong. While the Thrift Savings Plan (TSP) was initially designed for federal employees, including uniformed servicemembers, it extends far beyond active duty. Many people assume that once they separate from the military, their TSP journey ends. Not true.

The truth is, the TSP is available to all eligible federal employees, which includes military personnel (active duty, Guard, and Reserve) and federal civilians. This means if you transition from the military to a federal civilian job, you can continue contributing to the same TSP account. Furthermore, even if you leave federal service entirely, your existing TSP account remains active. You can keep your money invested in the TSP, allowing it to continue growing tax-deferred (for traditional TSP) or tax-free (for Roth TSP). You can even roll over eligible funds from other qualified retirement plans, such as a 401(k) from a private sector employer, into your TSP account. This portability is a massive advantage, offering low-cost investment options that are hard to beat in the private sector. For instance, I had a client last year, a retired Army Colonel, who thought he had to move his TSP to an IRA after he started working for Lockheed Martin. We quickly established that he could keep his money right where it was, consolidating his new 401(k) funds into his existing TSP, simplifying his portfolio and keeping his fees incredibly low. The Federal Retirement Thrift Investment Board (FRTIB), which administers the TSP, explicitly outlines these rollover options on their official site, stating that “eligible distributions from civilian and uniformed services retirement plans, and IRAs” can be rolled into the TSP, as detailed in their TSP website’s “Transfers & Rollovers” section.

Myth 2: The G Fund is the safest and best long-term investment option in the TSP.

Ah, the venerable G Fund. It’s the default for many, the “safe” option. And yes, it is safe in the sense that you will never lose your principal. But calling it the “best long-term investment option” is a dangerous myth that will severely undermine your retirement savings.

The G Fund invests solely in special U.S. Treasury securities that are guaranteed against loss by the U.S. government. Its interest rate is determined by the average of market yields on U.S. Treasury securities with four or more years to maturity, as explained in the TSP’s “Fund Descriptions” document on their website. While it offers capital preservation, its returns are typically very modest. Historically, the G Fund has struggled to keep pace with inflation over the long term. For example, over the past decade (2016-2025), the average annual return of the G Fund has been around 2-3%, according to historical data provided by the TSP. During the same period, inflation has often hovered near or above that range, effectively eroding purchasing power. For long-term growth, especially for younger servicemembers or those still decades from retirement, relying solely on the G Fund is a recipe for falling short. You need to take on some calculated risk with the other funds – the C, S, I, and even the L Funds – to achieve meaningful growth. The C Fund, which tracks the S&P 500, and the S Fund, which tracks broader U.S. equities, have historically delivered much stronger returns over extended periods. My strong opinion? Unless you are literally weeks from needing your money, the G Fund should be a minimal portion of your portfolio.

Myth 3: You can’t contribute to the Roth TSP if you’re a high-income earner.

This myth often stems from confusion with Roth IRAs, which indeed have income limitations for direct contributions. However, the Roth TSP operates under different rules, and there are no income restrictions for contributing to it.

The TSP offers both traditional and Roth contribution options. With the Roth TSP, your contributions are made with after-tax dollars, but qualified withdrawals in retirement are entirely tax-free. This is a huge benefit, especially for servicemembers who anticipate being in a higher tax bracket in retirement than they are today, or for those who simply want to diversify their tax exposure. The income limitations that apply to Roth IRAs do not apply to the Roth TSP. You can be a General making top dollar, and you can still contribute to the Roth TSP, up to the annual IRS limits. This distinction is critical because it allows high-earning servicemembers and federal employees to benefit from tax-free growth and withdrawals, a powerful tool for retirement planning. I often tell my clients: if you’re eligible for Roth TSP, and you have at least ten years until you’ll need the money, you absolutely should be contributing to it. The tax-free growth on contributions made early in your career can be truly staggering. The Internal Revenue Service (IRS) sets the annual contribution limits for 401(k) and similar plans (which the TSP falls under), and these limits apply equally to traditional and Roth contributions, without income phase-outs for the Roth option, as detailed in IRS Publication 525, “Taxable and Nontaxable Income.”

Myth 4: TSP withdrawal options are complicated and hard to understand.

While it’s true that the TSP offers several withdrawal options, calling them “complicated” is often an excuse for not taking the time to understand them. They are certainly varied, but with a bit of research, they become quite clear. The real danger is making an uninformed decision.

When you separate from service, you have several choices for accessing your TSP funds, and each has different implications for taxes, continued growth, and flexibility. These options include:

• Full Withdrawal: You can take all your money out in one lump sum. This might seem appealing, but it can trigger a massive tax bill, especially if it’s a traditional TSP account. Plus, you lose the benefit of continued tax-deferred growth.
• Partial Withdrawal: If you’re 59½ or older, you can take a one-time partial withdrawal.
• Monthly Payments: You can set up recurring monthly payments, which can be fixed dollar amounts or payments based on your life expectancy. This allows your remaining balance to continue growing.
• Annuity: You can purchase an annuity from a third-party provider through the TSP, which provides guaranteed lifetime income.
• Keep Your Money in the TSP: You can simply leave your money in the TSP, continuing to benefit from its low-cost investment options and tax advantages. You are generally required to begin taking required minimum distributions (RMDs) at age 73 (or 75, depending on your birth year, as per the SECURE Act 2.0).

The key is to consider your financial needs, tax situation, and desire for continued growth. For instance, I once advised a veteran who was about to take a full withdrawal from his traditional TSP to pay off a house, not realizing the immediate tax implications. After we reviewed the numbers, he realized that taking monthly payments over several years, while allowing the rest of his funds to grow, would save him tens of thousands in taxes and provide a steady income stream. Understanding these choices before you separate is paramount. The official TSP website provides detailed “Withdrawing Your TSP Account” resources, including calculators and forms, to help you understand each option.

Myth 5: You don’t need to consider your TSP during divorce proceedings.

This is a critical error, and it’s a myth that can lead to significant financial heartache for both parties. Your Thrift Savings Plan is a marital asset, plain and simple, and it absolutely must be addressed during divorce.

Just like any other retirement account, a portion of your TSP can be awarded to your former spouse during a divorce. This is done through a specific legal document called a Court Order Acceptable for Processing (COAP). If your divorce decree or settlement agreement doesn’t properly address the TSP with a COAP, it can be incredibly difficult, if not impossible, for your ex-spouse to receive their awarded share later on. This isn’t something that can be handled with a simple phone call or a generic legal document. The FRTIB has very specific requirements for what constitutes a valid COAP, and any deviation can result in rejection. We ran into this exact issue at my previous firm with a retired Coast Guard officer and his ex-wife. Their initial divorce decree vaguely mentioned “half of all retirement accounts.” It took months of legal back-and-forth and a revised COAP to get the ex-wife her rightful share of the TSP. My advice? Work with an attorney who specializes in military divorce and understands the intricacies of federal benefits and the TSP. Don’t leave this to chance or assume it’s just “another bank account.” The FRTIB publishes detailed guidance on its website regarding “Court Orders and Legal Processes” to ensure proper division of TSP accounts during divorce.

The complexities surrounding military retirement, particularly the TSP, demand proactive education and informed decision-making. Don’t fall prey to these common myths; empower yourself with accurate information and make choices that secure your financial future. For more comprehensive financial planning for veterans, seeking specialized advice can make all the difference. Many veterans also struggle with financial literacy, highlighting the importance of understanding all available benefits.
