Most soldiers know about the TSP. Almost none of them have a Roth IRA. That gap is costing them hundreds of thousands of dollars in tax-free wealth. Here is exactly why you need one — and how to open it today.
I opened my first Roth IRA in 2018. I was 30 years old, working multiple jobs, and had no idea what I was doing. What I did know was this: the government was offering me a legal way to grow my money completely tax-free, and I was not going to say no.
Eight years later, that account is one of the biggest reasons I am sitting at $750,000 net worth today.
If you are in the military and you do not have a Roth IRA yet, this post is for you.
What Is a Roth IRA — and Why Should Soldiers Care?
A Roth IRA is an individual retirement account that you fund with money you have already paid taxes on. In return, every dollar inside that account — and every dollar of growth — is completely tax-free for the rest of your life.
Compare that to a traditional IRA or TSP, where you get a tax break today but pay taxes when you withdraw in retirement. With a Roth IRA, there is no tax bill waiting for you on the other side. Zero. What you see is what you keep.
For soldiers, this is especially powerful for one reason: you are likely in one of the lowest tax brackets of your life right now. Paying taxes on a modest E-4 or E-5 salary today to protect a much larger retirement balance from taxes later is one of the smartest trades in personal finance.
The Combat Zone Advantage Almost Nobody Talks About
Here is the benefit that most soldiers completely miss.
If you are deployed to a designated combat zone and receiving tax-free combat pay, you can contribute that tax-free income directly into a Roth IRA. That means the money goes in without being taxed and comes out in retirement without being taxed.
You pay taxes on it exactly zero times.
I did not fully understand this when I first opened my account. When I finally did, I made sure to maximize every combat zone contribution I could. If you are currently deployed or have upcoming orders, this is the single most important financial move you can make right now.
How the Roth IRA Works Alongside Your TSP
A common question I get from soldiers: "I already have a TSP — do I really need a Roth IRA too?"
Yes. Here is why they serve different purposes:
Your TSP is your employer-sponsored plan. It has a high contribution limit ($24,500 in 2026) and may come with employer matching under BRS. This is where the bulk of your retirement savings should go.
Your Roth IRA is your personal account that you control completely. It is not tied to your employer, your service, or your duty station. When you separate from the military — whether at four years or twenty — your Roth IRA comes with you, fully intact, with no paperwork and no rollover required.
The two accounts work together. Think of your TSP as the engine and your Roth IRA as the turbocharger.
Priority order:
- TSP — contribute at least 5% to capture the full BRS match
- Roth IRA — max it ($7,500 in 2026)
- TSP — go back and increase your contribution toward the $23,500 limit
- Everything else after that
How to Open a Roth IRA in 15 Minutes
This is the part most people overthink. It is genuinely simple.
Step 1 — Choose a provider.
I use Vanguard. Fidelity and Charles Schwab are equally excellent. All three are free to open, have no account minimums, and offer low-cost S&P 500 index funds. Pick one — it does not matter which.
Step 2 — Open the account online.
Go to vanguard.com, fidelity.com, or schwab.com. Click "Open an Account." Select "Roth IRA." Fill in your personal information. Takes about 10 to 15 minutes.
Step 3 — Fund it.
Link your bank account and transfer your first contribution. You can start with as little as $10. The 2026 annual limit is $7,500 if you are under 50.
Step 4 — Invest the money.
This is where most new investors freeze. Do not freeze. Buy one fund: VFIAX at Vanguard, FXAIX at Fidelity, or SCHX at Schwab. All three track the S&P 500. Set up automatic monthly purchases if you can. Then leave it alone.
The Math That Should Motivate You
Let me show you a number that changed how I think about money.
If you open a Roth IRA at 25 and contribute $500 per month until you are 55, you will have contributed $180,000 of your own money. At a 10% average annual return — which is the long-term historical average of the S&P 500 — your account will be worth approximately $1.13 million.
Every dollar of that $1.13 million is tax-free.
Now consider what happens if you wait ten years and start at 35 with the same $500 per month. By 55, you will have contributed $120,000. Your balance: approximately $380,000.
The difference between starting at 25 and starting at 35 is not $60,000. It is $750,000 in tax-free wealth.
Time is the most powerful variable in this equation. You cannot buy it back.
Start Today — Not Tomorrow
When I was helping a fellow soldier set up his finances, the first thing I asked him was whether he had a Roth IRA. He did not. We opened one together in under 20 minutes. He told me later it was the most important financial move he had made in his life.
You do not need to understand everything about investing to open a Roth IRA. You just need to open it, put money in, and buy an S&P 500 index fund. Everything else is details.
The best time to open a Roth IRA was when you first enlisted. The second best time is today.
