Traditional vs. Roth: Picking Which Tax Bill You’d Rather Pay

We hear it all the time: traditional or Roth? We’ve watched clients wrestle with this for years. The difference between the two contribution types isn’t just philosophical. It runs through the timing of taxation, the contribution rules, income limits, and eligibility thresholds that all shift depending on your filing status and whether you or your spouse have a retirement plan at work. We’ll walk through how each account works, where the 2026 numbers land, and what might actually help you make the call between a Roth or traditional IRA.

Roth vs. Traditional IRA: When Do You Pay Taxes?

Here’s the thing: every dollar in an IRA eventually gets taxed one way or another. The real question is when the IRS collects its share. That timing is what separates these two accounts at their core, and it’s the question we walk every client through before they contribute a single dollar.

Traditional IRA: A Possible Tax Deduction Now, Taxable Withdrawals Later

A traditional IRA is essentially a “pay later” bucket. You contribute pre-tax or tax-deductible dollars, and the account grows tax-deferred. No taxes are owed on interest, dividends, or capital gains while the money stays invested. Anyone with earned income can contribute, though whether that contribution is actually deductible is a different question. If you or your spouse have a workplace retirement plan like a 401(k), your deduction can shrink or disappear entirely once modified adjusted gross income crosses certain thresholds.

Once you hit 59½, withdrawals are penalty-free, but deductible contributions and earnings still count as ordinary income. Pull money out before that age, and you’re generally looking at a 10% additional tax on top of regular income tax, unless an exception applies. For some clients, deferring that tax bill makes real sense. It depends on where their income sits now versus where they expect to land in retirement.

Roth IRA: After-Tax Contributions, Tax-Free Qualified Withdrawals

A Roth IRA flips the order. It’s not a tax break today, but really a tax break later. You fund it with after-tax dollars, so there’s no upfront deduction, but qualified distributions come out completely tax-free. Your original contributions can come back out at any time, no taxes, no penalties, because you’ve already settled that bill.

Earnings are a different story. Pull them out before age 59½ and before the account has been open five years, and you may owe both income tax and a 10% penalty, though exceptions exist, including a first-time home purchase up to a $10,000 lifetime cap and certain qualified education expenses. Meet both conditions (the age requirement and the five-year holding period) and the earnings come out tax-free too.

Both Accounts Can Hold the Same Investments

Here’s something that genuinely surprises people when we bring it up: the IRA type doesn’t restrict what you invest in. Both traditional and Roth accounts can hold stocks, bonds, mutual funds, ETFs, and CDs. The law does prohibit a few categories, like life insurance and most collectibles, with narrow exceptions for certain precious metal, but the investment menu is otherwise identical.

What changes is the tax treatment wrapped around it. That’s really where a fiduciary CFP^® professional earns their keep — matching the account structure to your actual tax picture, your income today, your expected bracket in retirement, and your withdrawal timeline — rather than just guessing which wrapper sounds better.

IRA Income Limits and Contribution Rules

Here’s where things get a little more specific, and a little more tricky.

Earned Income and Annual Contribution Limits

To contribute to either account type, you need taxable compensation, like wages, salaries, commissions, or self-employment income. There’s no age ceiling on contributing, which surprises people. For 2026, the combined cap across all your traditional and Roth IRAs is $7,500, or $8,600 if you’re 50 or older, or 100% of your taxable compensation, whichever is smaller. A nonworking spouse can fund an IRA under that same limit, as long as the working spouse earns enough to cover both contributions.

Roth IRA Income Limits by Filing Status

Roth eligibility narrows as income climbs. Here’s how the 2026 phase-out ranges break down by filing status:

Filing Status                                       Full Contribution                                       Phase-Out Range                                               Ineligible

Single/Head of Household            Under $153,000                                           $153,000–$168,000                                               $168,000+

Married Filing Jointly                      Under $242,000                                         $242,000–$252,000                                              $252,000+

Married Filing Separately                          N/A                                                          Under $10,000                                                  $10,000+

Traditional IRA Deduction Limits and Workplace Plan Coverage

A traditional IRA carries no income ceiling for contributing, but deducting that contribution is a different matter entirely, and it depends on workplace plan coverage. If neither you nor your spouse has a retirement plan at work, your deduction stays full regardless of what you earn. If you’re covered by a plan at work, the 2026 deduction phases out between $81,000 and $91,000 for single filers, and between $129,000 and $149,000 for joint filers. When only your spouse is covered, that range runs from $242,000 to $252,000.

Contribution Deadlines and the Shared Limit Across Both IRAs

You have until April 15 of the following year to contribute. And that $7,500 – or $8,600 – cap applies across both accounts combined, not to each one separately. That’s an important distinction. Our team can help you think through how to split contributions strategically, match the right account to your tax picture, and make sure you’re not leaving anything on the table.

How Withdrawal Rules Affect Your Retirement Tax Bill

Contribution timing matters, sure, but withdrawal timing shapes your tax bill just as much, and the two account types diverge the moment money starts coming out.

Roth Contributions vs. Earnings: What You Can Withdraw Tax-Free

Since you already paid tax on Roth contributions, that money is yours to pull out anytime with no income tax and no penalty. The IRS does set a specific order for withdrawals: contributions come out first, then conversions, then earnings. That sequence matters more than most people realize, because it determines exactly when a distribution starts touching the portion that could actually owe tax.

Age 59½ and the Roth IRA Five-Year Rule

Tax-free earnings require two things at the same time: you’re at least 59½, and the account has been open five years. That five-year clock starts January 1 of the year you made your first contribution, and each conversion you do carries its own separate five-year period if you’re under 59½. Missing either condition changes what you owe.

Early Withdrawal Exceptions: Penalty-Free Does Not Always Mean Tax-Free

Early withdrawals (generally anything before 59½) trigger a 10% additional tax on either account type unless an exception applies. The exceptions are more specific than most people expect. They include a first-time home purchase up to $10,000, birth or adoption costs up to $5,000 per child, medical expenses above 7.5% of adjusted gross income, disability, death, an IRS levy, and federally declared disasters up to $22,000.

Here’s the part that catches people off guard: clearing the penalty doesn’t clear the tax bill. Some exceptions only waive the 10% charge – the underlying income tax still applies. We always recommend confirming which exception actually fits your situation before any funds move.

Traditional IRA Required Minimum Distributions by Birth Year

Traditional IRAs carry one deadline that Roth accounts skip entirely: required minimum distributions, calculated each year from your account balance and life expectancy. The age depends on when you were born:

• Before July 1, 1949, RMDs started at 70½
• 1949–1950 at 72
• 1951–1958 at 73
• 1960 or later, at 75

The first RMD is due by April 1 following that birthday year, then December 31 every year after that. Miss one, and you’re looking at a 25% excise tax, though that drops to 10% if corrected within two years.

Roth IRAs: No Required Withdrawals During the Owner’s Lifetime

Original Roth owners face no such deadline. The money can stay invested and keep growing tax-free for as long as you live. That flexibility ends once a beneficiary inherits the account. Inherited Roth IRAs follow their own RMD rules. It’s a distinction our team weighs heavily when we’re comparing Roth versus traditional accounts for retirement income planning: the tax-free growth, the withdrawal control, the absence of a forced distribution schedule.

Should You Choose a Roth or Traditional IRA?

This really isn’t a lifestyle question. It’s a math problem, and the math is rooted in your tax rate today versus what you expect to pay down the road.

Compare Your Current and Expected Future Marginal Tax Rates

If your bracket today sits higher than where you expect to land in retirement, the traditional IRA’s deduction often carries more weight. If the reverse looks true – if you expect to be in a higher bracket later – the Roth’s tax-free withdrawals may win out. We’ve seen clients assume they’ll always be in a lower bracket in retirement, and that assumption doesn’t always hold up once you factor in Social Security, RMDs, and other income sources.

Run the Numbers With Traditional Tax Savings Reinvested

A saver in the 22% bracket contributing $7,500 could see roughly $1,650 in tax savings from the traditional deduction. But here’s where it gets interesting: that only changes the comparison meaningfully if you actually reinvest those savings rather than spend them. Most people spend them. That’s not a criticism; it’s just what the data shows, and it matters when you’re doing the side-by-side.

Factor In State Taxes, Social Security, and Medicare Premiums

The federal bracket isn’t the whole story. Traditional withdrawals can push up how much of your Social Security gets taxed and trigger Medicare premium surcharges (what’s called IRMAA) factors that effectively raise your marginal rate well beyond what the bracket alone suggests. We think about this a lot when we’re building retirement income plans, because the real tax rate in retirement is rarely just the number on the bracket chart.

Use Both Account Types When Future Tax Rates Are Uncertain

Splitting contributions – sometimes called tax diversification – hedges against not knowing where rates will sit later. It’s not a complicated strategy. It’s really just a way of not betting everything on one outcome.

If You Exceed Roth Income Limits, Review the Backdoor Option Carefully

A backdoor Roth conversion may trigger taxes applied proportionally across all IRA balances; what the IRS calls the pro-rata rule. It’s one of those areas where the move looks clean on the surface but can get complicated fast depending on what else you have sitting in traditional IRA accounts.

Revisit This Decision When Your Situation Changes

Income changes, workplace plan coverage changes, retirement timelines shift. The right answer at 35 may not be the right answer at 50. Our team can help you reassess the mix as those pieces move.

The short version: compare your tax rates, run the actual numbers, account for state taxes and Social Security, and hedge with both account types when the future is uncertain.

Review Your IRA Tax Choice

Traditional and Roth IRAs essentially ask you to pay taxes now or later, and the right answer depends on your current bracket, future plans, and workplace coverage. Tax diversification can help hedge uncertainty, while a fiduciary CFP^® professional can match the account to your actual numbers rather than guesswork. Sooner or later, this decision affects your retirement income, so book an appointment with me to review your IRA tax choice before contributing this year.
