Traditional vs Roth IRA: What Most Advisors Won’t Tell You

Written by Mark J. Kohler | Feb 20, 2026 10:29:05 PM

That last-minute call before you file your return can cost you a fortune later. Not because your advisor is evil, but because the default advice is usually lazy, and you are the one who gets stuck paying tax on the back end when the account is finally worth something. Here’s how to think about Roth vs traditional the way real business owners do.

Traditional vs Roth in Plain English

A traditional IRA or traditional 401(k) gives you a write-off today. You put money in, it lowers taxable income, and you feel like you got a win. Then the money grows, and the bill shows up later. Every dollar you pull out is taxable, including the growth. A Roth flips that. No write-off when you contribute, but the growth can come out tax-free later. That’s the whole game. It’s not complicated, but it’s easy to underestimate how painful it is to pay tax on the full account value after decades of compounding.

Here’s the problem with chasing the write-off. People love the idea of saving tax on the contribution, but they ignore what happens when that contribution turns into something meaningful. Saving tax on the seed feels good. Paying tax on the harvest is where it hurts.

The Lower Tax Bracket in Retirement Myth

This is the classic line. You’re going to be in a lower bracket later, so take the write-off now. Sounds clean. Sounds responsible. It also assumes your retirement plan is to earn less, live on less, and somehow be thrilled about it. That’s not how most successful business owners actually live.

The clients who save aggressively, invest, buy real estate, build businesses, and stack income streams usually have more taxable income in retirement than they expected. They may not be grinding every day, but they are still earning. Cash flow from rentals. Business income. Notes. Investment income. A business sale payout. And then the tax rate you thought would drop just sits there, or gets worse.

Why Roth Money Is the Best Money

Roth accounts give you options. Not theory. Not calculator math. Real options.

First, Roth money is the best money to leave to your kids. If your kids inherit a traditional retirement account, they’re pulling taxable money during their working years. They’re likely in their peak earning window, and the IRS is waiting. A Roth inheritance is completely different. They can let it grow and then pull it out tax-free under the rules. That’s a wealth transfer tool, not just a retirement account.

Second, Roth contributions are more flexible than people realize. With a Roth IRA, the money you contributed can be accessed without tax or penalty. It’s not the growth, it’s the contributions. That matters when life happens, when an opportunity shows up, or when you want a cushion you can reach if you absolutely have to.

Third, Roth money is the best place to put your best deals. If you’re the type of investor who can turn a great investment into a big win, you don’t want to build that win inside an account that’s going to be fully taxable on the way out. That is the part so many advisors never address because their entire strategy starts and stops with the write-off.

The Self-Directing Factor Changes the Math

If you’re a basic index fund investor, Roth vs traditional can look like a wash on paper. That assumes tax rates never change, you invest every penny of the tax savings, and you never touch the money early. In the real world, people don’t invest the tax savings with perfect discipline, and tax planning doesn’t happen in a vacuum.

Now add self-directing. If your retirement account can invest in the assets you actually understand, real estate, private deals, notes, and other alternatives, the upside can be far bigger than the typical Wall Street return. And the bigger the upside, the more attractive Roth becomes. Because the traditional write-off is tied to the contribution amount. The tax bill later is tied to the full account value. If the account grows fast, the traditional account creates a giant future tax problem. A Roth turns that same growth into tax-free upside.

This is why I keep coming back to a simple idea. I would rather pay tax on the small number once, than pay tax on the bigger number later.

The Hybrid Approach and the Real Deadline You Should Care About

Do you need to be 100% Roth forever? Not necessarily. Having a mix of account types can give you flexibility later. There are situations where pulling from a traditional account at the right time could make sense. But if you are building wealth and stacking income, the account you can never regret is the Roth.

And let me add one more practical point. Don’t use the tax filing deadline as your financial planning system. If you’re waiting until the last minute every year to decide what to do, you’re already behind. These accounts are investment accounts first. The earlier money gets in, the more time it has to grow.

If you normally skip the contribution because you don’t want to give up the write-off, you’re missing the point. Do something. Fund the Roth. Automate it. Make it boring. That’s how you build real wealth.

The Bottom Line

If you understand how these accounts work, you stop obsessing over a write-off and start focusing on what you’re actually building. Roth accounts create tax-free optionality, tax-free retirement income, and one of the cleanest wealth transfers you can hand your kids. Traditional accounts can have a place, but they are not the automatic default a lot of advisors make them out to be.
