What 20 Years of Managing My Own Accounts Taught Me About Roth vs Traditional

I still remember 2007, when I was deep in the weeds of my own retirement account strategy and realized something that stuck with me. The advice circulating everywhere back then was to put everything into a traditional IRA for the upfront deduction, and almost nobody running that playbook had modelled it. Take a fairly ordinary case: someone 34, earning $68,000 a year, planning to retire early. Once you map out the full tax picture — current bracket, expected retirement income, Social Security timing, and state tax treatment — it becomes obvious how much that reflex can leave on the table.

That moment crystallized something I have spent two decades learning through my own obsessive account optimization: the question of Roth IRA vs traditional IRA which is better does not have a universal answer. It has a correct answer for your specific situation, and getting it wrong costs real money. Here’s what 20 years of managing my own accounts and running my own numbers across nearly every income level and tax scenario has taught me.

Why the Standard Advice Is Too Simplistic

Most articles will tell you: if you expect to be in a higher tax bracket in retirement, choose Roth. If you expect a lower bracket, choose traditional. That framework is not wrong — it is just dangerously incomplete.

Here is what those articles leave out:

• Tax bracket expectations are notoriously hard to predict. In 2003, almost no one anticipated the Tax Cuts and Jobs Act of 2017, which temporarily lowered rates and created one of the best Roth conversion windows we have seen in modern history. Those windows open and close, and you cannot time them if you have committed all your money to one account type.
• Required Minimum Distributions (RMDs) change the math significantly. Someone with $2.1 million in a traditional IRA at age 73 can easily be pushed into the 22% or even 24% bracket by RMDs alone — even if they are spending modestly. I’ve seen this happen repeatedly when managing my own accounts and studying tax outcomes. Roth accounts have no RMDs during the owner’s lifetime.
• Medicare premiums are bracket-sensitive. IRMAA surcharges kick in at specific Modified Adjusted Gross Income thresholds. In 2024, a married couple crossing $206,000 in MAGI can pay hundreds of extra dollars per month in Medicare Part B and D premiums. Traditional IRA withdrawals count toward that number. Roth withdrawals do not.

The real decision is not just about your marginal rate today versus your marginal rate at age 70. It is about tax diversification, flexibility, and managing multiple moving parts across decades.

The Cases Where Traditional Wins — Clearly

I want to be honest here, because too much Roth content is written by people who seem to think traditional accounts are always inferior. They are not.

Traditional IRAs and 401(k)s make the most sense when:

• You are in the 32%, 35%, or 37% federal bracket right now and have strong evidence you will be in a significantly lower bracket in retirement. A partner who is a surgeon at peak earnings years but plans to retire at 58 is a real candidate for traditional contributions today.
• Your state has high income taxes that you will escape in retirement by moving. I’ve seen the math work out for people who worked in California or New York and retired to Florida or Texas—that state tax delta alone can be worth the traditional deduction.
• You need the immediate cash flow benefit. If you’re operating with a tight monthly budget, the traditional deduction reduces your current tax bill in a way that lets you contribute more overall. A higher contribution today at a modest tax cost can outperform a smaller Roth contribution.

The Cases Where Roth Wins — Often More Than People Realize

For the majority of the families I hear from — particularly those in the 22% and 24% brackets — Roth accounts have proven to be the better long-term tool. Here is why.

First, tax rates have more room to rise than fall from current levels. The TCJA provisions are set to expire after 2025. If Congress does not act, brackets will revert to pre-2018 levels, which means someone currently in the 22% bracket could find themselves in the 25% bracket without earning a single dollar more. Locking in today’s rates with Roth contributions is a form of tax insurance.

Second, Roth accounts are more valuable than the nominal math suggests. A $7,000 Roth contribution and a $7,000 traditional contribution are not equivalent. The Roth account holds $7,000 of after-tax money. The traditional account holds $7,000 of pre-tax money. To compare them honestly, the traditional contribution requires you to account for the future tax liability embedded inside it.

Third, estate planning advantages are real. Roth IRAs pass to heirs income-tax-free. Under the SECURE Act 2.0, most non-spouse beneficiaries must distribute inherited IRAs within 10 years — but Roth distributions remain tax-free, while traditional distributions pile on top of the heir’s ordinary income. For anyone with a taxable estate, this difference can be substantial.

The Strategy I Use Most: Staged Roth Conversions

The most powerful tool I deploy is not choosing between Roth and traditional at contribution time — it is doing strategic Roth conversions in the years between retirement and Social Security or RMD onset. I call this the “conversion window,” and it is often the highest-leverage tax planning available to pre-retirees.

Here is what it looks like in practice: Someone retires at 62 with $900,000 in a traditional 401(k) and $120,000 in a Roth IRA. Before Social Security kicks in at 67 and before RMDs begin at 73, they have five to eleven years of relatively low taxable income. In that window, the strategy is to systematically convert traditional dollars to Roth — filling up the 12% or 22% bracket each year — at rates that are almost certainly lower than what their RMDs would have forced later.

Over the course of a decade, this approach can reduce lifetime tax burden by $80,000 to $200,000 for the right client. It requires discipline, cash flow planning, and ACA subsidy awareness (conversions increase MAGI, which affects marketplace health insurance premiums during the gap years), but it is one of the most consistently effective strategies I have built.

An Honest Caveat

I want to be clear about one limitation: no one can predict future tax law with certainty. I have been wrong about specific legislative outcomes before, and so has every other planner you will meet. The value of tax diversification — holding both Roth and traditional assets — is precisely that it hedges against legislative uncertainty. If you force yourself to pick only one type of account forever, you are making a bet on something unknowable. Holding both types and optimizing the ratio over time is usually more robust than optimizing for the “right” answer at age 30 that may not age well.

The Bottom Line After 20 Years

The Roth vs. traditional IRA debate is one of the most consequential financial decisions most people make — and it is treated too casually by most of the content available online. The right answer depends on your current bracket, your expected retirement income, your state tax situation, your estate goals, and your ability to capitalize on conversion windows. It also depends on tax law that will change in ways none of us can fully anticipate.

What I’ve learned from 20 years of managing my own accounts is this: build flexibility into your system, run the actual projections for your actual numbers, and revisit the decision every few years as your circumstances evolve. The approach that has fared best over the years is not making the “right” choice once — it’s staying engaged, adjusting, and working the math continuously.

That is the real edge, and it is available to anyone willing to take it seriously.

The Visual Tool That Made the Roth vs. Traditional Decision Click

After two decades of tax planning conversations, I realized the biggest barrier to making the right choice isn’t lack of information—it’s the inability to *see* how your decision actually plays out across decades. Running mental math or spreadsheet projections only gets you so far when you’re trying to compare two fundamentally different tax futures.

What works

• Lets you input your actual numbers—current income, expected retirement income, state taxes—and immediately *see* the dollar difference between Roth and Traditional paths side by side, turning abstract tax theory into concrete outcomes.
• Handles the messy real-world scenarios: early retirement timelines, Social Security coordination, state tax treatment, and contribution limit changes across multiple years—the exact variables that make this decision so slippery.
• Removes the emotional guessing that trips people up; instead of relying on your coworker’s experience or generic advice, you can test your specific situation and see where the math actually favors you.

What doesn’t

• Won’t replace a full tax plan with a CPA—it’s a simulation tool, not tax advice, so you’ll still need professional eyes on edge cases like backdoor Roths or spousal IRA strategy.
• Requires you to make assumptions about future income, tax rates, and retirement spending; if you’re genuinely uncertain about those inputs, the tool can only show you scenarios, not predict the future.

I’ll admit: when I first tested this approach with my own numbers, I was skeptical that a visual simulator could beat the spreadsheets I’d been building for years. But within minutes, I saw patterns in my tax liability across decades that my rows and columns had buried.
