I still remember the client who came into my office in 2007 convinced she needed a traditional IRA because her coworker told her so. She was 34, earning $68,000 a year, and planning to retire early. She had never run a single projection. Neither had her coworker. After building out her full tax picture — current bracket, expected retirement income, Social Security timing, and state tax treatment — it was clear she was leaving tens of thousands of dollars on the table with that assumption.
That meeting crystallized something I have spent two decades reinforcing with every client I work with: 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. Let me walk you through what I have actually learned from building these strategies for hundreds of clients across almost every income level and tax scenario imaginable.
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. A client 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 have watched this happen dozens of times. 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 have clients 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. For clients with tight monthly budgets, the traditional deduction reduces their current tax bill in a way that lets them 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 my clients — 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 clients with taxable estates, 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: A client 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, I 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.
Resources I Recommend
If you want to go deeper on this topic, here are three resources I genuinely recommend, whether you are just starting out or looking to sharpen your conversion strategy.
For beginners who want a clear, step-by-step foundation: Roth IRA & 401(k) Investing for Beginners 2026: A Simple Step-by-Step Guide to Build Wealth, Lower Taxes, and Start With Small Amounts. This is the kind of resource I wish more of my early clients had read before our first meeting.
For visual learners who want to see how different contribution and conversion scenarios actually play out: Roth IRA as a Simulator: Visual Scenarios for Tax-Free Growth, Contribution Limits, and Roth vs. Traditional IRA Decisions. Running scenarios is exactly how I work with clients, and seeing the numbers visually makes the trade-offs concrete in a way that abstract explanations often do not.
For those approaching or already in early retirement who want advanced conversion and withdrawal strategies: Tax Planning To and Through Early Retirement. This covers the conversion window strategy, IRMAA management, and sequencing decisions in serious depth.
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 tell clients 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 clients who have fared best over my career are not the ones who made the “right” choice once — they are the ones who stayed engaged, adjusted, and worked the math continuously.
That is the real edge, and it is available to anyone willing to take it seriously.
