Roth vs. Traditional IRA: Which Fits Your Financial Plan?
For most of the clients I work with at Melby Wealth Management, the Roth vs. Traditional IRA question comes up within the first two meetings. It sounds simple on the surface, but the right answer depends on variables that are specific to each person's financial picture: current marginal tax rate, expected retirement income, whether a workplace plan is in play, existing pre-tax balances, and how much tax diversification already exists across accounts.
As a CERTIFIED FINANCIAL PLANNER® (CFP®) professional running a fee-only fiduciary firm in Nashville, my goal in writing this is to walk through the framework I use with clients rather than offer a generic comparison chart.
The Tax Bracket Question Is Only the Starting Point
The standard advice is straightforward: if your tax rate will be higher in retirement, choose Roth; if lower, choose Traditional. That logic is sound, but in practice the decision is rarely that clean.
Most of the higher-earning professionals I work with are in the 22% or 24% federal bracket during their peak accumulation years. The question then becomes: what will your effective rate be when you're drawing down? If you have a pension, significant pre-tax 401(k) balances, and Social Security all stacking in retirement, your effective rate could easily match or exceed your current rate. In that case, having paid taxes on Roth contributions at today's rates looks like a strong move in hindsight.
For clients in the 32% bracket or above who are confident their retirement income will drop meaningfully (perhaps because they plan to retire early or live in a lower-cost state), the Traditional deduction at a high rate creates real tax arbitrage. The key word is "confident." Tax rates are a policy decision, and policy changes over a 30-year horizon.
Where the Advisor Conversation Changes the Outcome
In my experience, the clients who benefit most from professional guidance on this question are the ones with financial complexity that makes the generic advice misleading.
Backdoor Roth eligibility. In 2026, single filers above $168,000 MAGI and married couples above $252,000 cannot contribute directly to a Roth IRA. The Backdoor Roth strategy (contribute to a non-deductible Traditional IRA, then convert) remains available, but the pro-rata rule makes it problematic if you have existing pre-tax IRA balances. This is the kind of nuance that a blog post can flag but an advisor can actually solve, because the answer depends on your specific IRA balances, rollover history, and tax filing status.
Asset location across account types. The Roth vs. Traditional question interacts with everything else: 401(k) contributions, HSA eligibility, taxable brokerage holdings, and equity compensation. For a client with RSUs vesting annually and a traditional 401(k) through their employer, the Roth IRA may be the only after-tax space available. That changes the calculus entirely.
Multi-year Roth conversion planning. For clients with large traditional IRA or rollover balances, we often model phased Roth conversions over several years to fill up lower tax brackets without triggering IRMAA surcharges on Medicare premiums. This is a coordination exercise that requires modeling across tax brackets, Social Security timing, and required minimum distributions.
Tax diversification as a planning tool. Having both pre-tax and post-tax money in retirement gives clients the ability to manage taxable income year by year. Large medical expense? Draw from the traditional account to capture the deduction. Low-income year between career and Social Security? Draw from the Roth to stay in a zero or low bracket. This optionality is difficult to quantify but shows up consistently when clients actually need it.
The 2026 Numbers
For reference, the current IRA contribution limit is $7,500 ($8,600 if 50 or older). The Traditional IRA deduction phases out at $81,000 to $91,000 for single filers covered by a workplace plan, and $129,000 to $149,000 for married filing jointly when the contributing spouse is covered. Roth IRA contributions phase out at $153,000 to $168,000 for single filers and $242,000 to $252,000 for married filing jointly.
These thresholds shift the decision for many of the professionals I work with. A dual-income household earning $260,000 combined has no direct Roth IRA access and may have a fully phased-out Traditional deduction. The planning work at that point is about finding the right combination of Backdoor Roth, Roth 401(k) if available, and taxable account positioning.
When Professional Guidance Matters Most
For a single-income earner in the 12% bracket with no workplace plan, the Roth vs. Traditional decision is genuinely simple. The Roth wins, and a blog post can walk you through it.
The picture gets more complex when you're navigating equity compensation, multiple account types, a spouse with different plan access, potential Roth conversions, or income that fluctuates between brackets year to year. In those cases, the coordination work across accounts, tax brackets, and time horizons is where a fee-only fiduciary adds value that compounds for decades.
If you're unsure whether your current IRA strategy fits your full financial picture, or if you're above the income limits and want to explore conversion strategies, I'm happy to walk through the math.
