When it comes to military retirement planning, service members have two powerful tools at their disposal: the Thrift Savings Plan (TSP) and the Roth IRA. Understanding the differences between these accounts is crucial for optimizing your military retirement savings strategy. In this article, we’ll break down both options, their advantages and drawbacks, and how to maximize your investments.

What is the Thrift Savings Plan (TSP)?

The TSP is the military’s version of a 401(k), offering a tax-advantaged way to save for retirement. It comes with low fees, automatic contributions (if you’re in the Blended Retirement System – BRS), and matching contributions from the Department of Defense (DoD) up to 5% of your base pay.

Pros of the TSP

• Low Fees – The TSP has some of the lowest expense ratios in the industry, keeping more money in your pocket over time.
• DoD Matching Contributions – If you’re in the Blended Retirement System (BRS), the DoD will match up to 5% of your base pay, essentially giving you free money.
• Traditional and Roth Options – You can contribute to either a Traditional TSP (pre-tax money) or a Roth TSP (after-tax money), giving you flexibility based on your tax situation.
• Automatic Payroll Deduction – Contributions are deducted straight from your paycheck, making saving effortless.
• Military Tax-Free Zones Benefit – If you make Roth TSP contributions while deployed in a tax-free combat zone, your withdrawals in retirement will be completely tax-free (both principal and gains).

Cons of the TSP

• Limited Investment Options – The TSP funds only include a handful of index funds (G, F, C, S, I, and L funds), limiting portfolio diversification compared to an IRA.
• Withdrawal Restrictions – Early withdrawals before age 59½ are subject to penalties unless you qualify for exceptions.
• Limited Access to Funds – You can’t withdraw contributions early without penalty, unlike a Roth IRA.

What is a Roth IRA?

A Roth IRA is an individual retirement account that allows you to contribute after-tax dollars, meaning your money grows tax-free, and withdrawals in retirement (after age 59½) are also tax-free.

Pros of a Roth IRA

• Tax-Free Growth and Withdrawals – Since you contribute post-tax money, all future gains and withdrawals are 100% tax-free.
• More Investment Choices – You can invest in stocks, ETFs, mutual funds, REITs, and even alternative investments like crypto or real estate.
• No Required Minimum Distributions (RMDs) – Unlike the TSP, Roth IRAs don’t require you to withdraw money at a certain age, giving you more control over your retirement savings.
• Early Withdrawal Flexibility – You can withdraw your contributions (but not earnings) at any time without penalty, giving you access to funds in an emergency.

Cons of a Roth IRA

• No DoD Matching – Unlike the TSP, there are no matching contributions, meaning you’re saving entirely with your own money.
• Contribution Limits – The Roth IRA contribution limit for 2024 is $7,000 ($8,000 if 50 or older), which is much lower than the TSP’s limit of $23,000.
• Income Restrictions – If your modified adjusted gross income (MAGI) exceeds $146,000 (single) or $230,000 (married filing jointly), you can’t directly contribute to a Roth IRA (though you can use a Backdoor Roth IRAstrategy).

Which One Should You Choose?

Best for Maximizing Free Money: TSP

If you’re eligible for matching contributions under the BRS, always contribute at least 5% of your base pay to the TSP first—otherwise, you’re leaving free money on the table.

Best for Tax-Free Growth and Flexibility: Roth IRA

If you want more control over your investments and tax-free withdrawals in retirement, a Roth IRA is a great supplement to the TSP. It also provides more liquidity since you can withdraw contributions penalty-free.

Best Strategy: Use Both!

The ideal approach is to contribute enough to the TSP to get the full match (5%), then max out a Roth IRA ($7,000 in 2024). If you have extra savings, contribute more to the TSP up to the IRS limit.

Bottom Line

Both the TSP and Roth IRA offer significant advantages to military members looking to build wealth. The best option depends on your financial goals, tax situation, and retirement plans. By strategically using both, you can maximize your military retirement savings while taking full advantage of tax benefits and investment flexibility.
