Traditional vs. Roth IRA (2026): Limits, Taxes and Which to Pick

The traditional IRA vs. Roth IRA decision comes down to one question: do you want your tax break now or later? With a traditional IRA, you may deduct your contribution today and pay income tax when you withdraw in retirement. With a Roth IRA, you contribute money you’ve already paid tax on, and qualified withdrawals — including decades of growth — come out tax-free.

If you expect to be in a lower tax bracket in retirement than you are today, a traditional IRA usually wins. If you expect the same or a higher bracket, or you’re early in your career, a Roth usually wins. Below, we’ll walk through the 2026 limits, the income rules that can lock you out of either tax break, a worked example with real numbers and the mistakes that cost people money.

Traditional vs. Roth IRA at a glance (2026)

Both accounts share the same annual contribution limit, and the limit is combined. You can’t put $7,500 in each — you can put $7,500 total across all your IRAs. Everything else is different.

You need earned income (wages, salary or self-employment income) to contribute to either account, and you can’t contribute more than you earned for the year. A non-working spouse can still fund a spousal IRA based on the working spouse’s income if you file jointly.

How a traditional IRA works

A traditional IRA lets your money grow tax-deferred. You don’t pay tax on dividends, interest or gains while the money stays in the account. You pay ordinary income tax when you take withdrawals, usually in retirement.

The big draw is the up-front deduction. If you’re in the 22% federal bracket and deduct a $7,500 contribution, you cut your federal tax bill by $1,650. Many states give you a break, too.

When your deduction gets limited

Anyone with earned income can contribute to a traditional IRA, but if you (or your spouse) are covered by a workplace retirement plan like a 401(k), your deduction phases out as your income rises. For 2026, the IRS sets these modified AGI ranges:

If your income is above the range, you can still make a nondeductible contribution. That money grows tax-deferred, but you’ll want to track your basis on IRS Form 8606 so you don’t pay tax twice when you withdraw.

How a Roth IRA works

A Roth IRA flips the tax timing. You contribute after-tax dollars, so there’s no deduction. In exchange, qualified withdrawals are completely tax-free. A withdrawal is qualified when you’re at least 59½ and it’s been at least five tax years since your first Roth contribution.

Roths also have two perks traditional IRAs don’t. First, there are no required minimum distributions during your lifetime, so your money can keep growing tax-free as long as you like. Second, you can pull out your contributions (not earnings) at any time without tax or penalty. That flexibility makes a Roth a decent backup emergency fund, though it works best when you leave it alone.

2026 Roth IRA income limits

Your ability to contribute directly to a Roth shrinks as your modified AGI rises:

• Single or head of household: full contribution below $153,000; partial between $153,000 and $168,000; none at $168,000 or more.
• Married filing jointly: full below $242,000; partial between $242,000 and $252,000; none at $252,000 or more.
• Married filing separately (lived with spouse): phases out between $0 and $10,000.

Over the limit? Many high earners use a “backdoor Roth”: make a nondeductible traditional IRA contribution, then convert it to a Roth. It’s legal, but if you hold other pre-tax IRA money, the IRS pro-rata rule makes part of the conversion taxable. Talk to a tax professional before you try it.

Worked example: which IRA leaves you with more?

Let’s make it concrete. Say you’re 35, in the 22% federal bracket, and you have $7,500 of pre-tax income to put toward retirement this year. We’ll assume a 7% average annual return for 30 years. (That’s a hypothetical return for illustration, not a promise — markets can do better or worse.)

• Traditional IRA: You contribute the full $7,500 and deduct it, so it costs you $7,500 of income with no tax today. After 30 years at 7%, it grows to about $57,092. Every dollar is taxable when you withdraw.
• Roth IRA: You first pay 22% tax on that $7,500, leaving $5,850 to contribute. After 30 years at 7%, it grows to about $44,532 — all tax-free.

Now apply your tax rate in retirement to the traditional balance:

The lesson: when your tax rate is the same now and later, the two accounts come out exactly even. The winner depends entirely on whether your rate goes up or down.

There’s one twist that favors the Roth. Because the limit is $7,500 either way, a Roth lets you shelter more real money. If you can afford to put a full $7,500 into a Roth (paying the tax from other income), it grows to about $57,092 tax-free. The same $57,092 in a traditional IRA is worth about $44,532 after 22% tax. If you’d otherwise spend the traditional IRA’s tax savings rather than invest them, the Roth often wins in practice.

Who should choose a traditional IRA

A traditional IRA tends to make the most sense if:

• You’re in a high bracket now (24% or above) and expect your income to drop in retirement.
• You qualify for the full deduction — for example, you don’t have a workplace plan, or your income is under the phase-out range.
• You need the deduction to lower your AGI, which can help you qualify for credits like the Saver’s Credit (available in 2026 to joint filers with AGI up to $80,500, heads of household up to $60,375 and single filers up to $40,250) or reduce taxes tied to income.
• You plan to retire in a state with lower or no income tax than where you live now.

The trade-off: you’ll owe tax on every withdrawal, and you must start required minimum distributions at 73 (or 75 if you were born in 1960 or later), whether you need the money or not.

Who should choose a Roth IRA

A Roth IRA tends to win if:

• You’re early in your career or in the 10%, 12% or 22% bracket and expect to earn more later.
• You can’t deduct a traditional contribution anyway because you have a workplace plan and your income is above the deduction range but below the Roth limit. A nondeductible traditional IRA is usually the weaker choice here.
• You want flexibility. Being able to withdraw contributions anytime, plus no RMDs, makes planning easier.
• You want tax diversification. If most of your savings sit in a pre-tax 401(k), adding Roth money gives you a tax-free bucket to draw from in retirement, which can help you manage your bracket year by year.
• You want to leave money to heirs. Beneficiaries generally must empty an inherited IRA within 10 years, but Roth withdrawals are typically tax-free for them.

Can you have both? Yes — and many people should

You can own a traditional IRA and a Roth IRA at the same time and split your contribution between them, as long as the total stays within $7,500 ($8,600 if 50+). For example, you could put $4,000 into a traditional IRA and $3,500 into a Roth.

Splitting is a reasonable hedge if you genuinely don’t know where tax rates will be in 30 years — and nobody does. It’s also common to pair a pre-tax 401(k) with a Roth IRA. If you have a workplace plan, our 401(k) vs. Roth IRA guide explains which to fund first. A typical order:

1. Contribute enough to your 401(k) to get the full employer match.
2. Fund a Roth IRA (or traditional, based on the rules above).
3. Go back and add more to your 401(k), up to the $24,500 limit for 2026.

If you have a high-deductible health plan, an HSA can also be a strong third bucket; see HSA vs. FSA for the 2026 limits.

Common IRA mistakes to avoid

• Leaving the money in cash. Opening an IRA isn’t the same as investing. Contributions often land in a money market sweep. Pick investments, such as a low-cost index fund or target-date fund. Our guide to investment strategies for beginners can help, or a robo-advisor can do it for you.
• Overcontributing. Excess contributions face a 6% excise tax each year they stay in the account. If you go over — or your income ends up above the Roth limit — withdraw the excess (and its earnings) before your tax filing deadline.
• Forgetting the five-year rule. Roth earnings aren’t tax-free until the account has been open five tax years and you’re 59½. Opening a Roth sooner, even with a small amount, starts the clock.
• Assuming you can’t contribute without a job. A spousal IRA lets a non-earning spouse save, as long as you file jointly and the working spouse has enough earned income.
• Missing the deadline. You can make 2026 contributions until April 15, 2027. Tell your broker which tax year the deposit is for.
• Taking early withdrawals casually. Traditional IRA withdrawals before 59½ are usually taxed plus a 10% penalty. Exceptions exist — including up to $10,000 for a first-time home purchase and qualified higher education expenses — but the lost growth still costs you.

Heads up for 2027: The IRS typically announces next year’s IRA limits and income ranges in October or November. Until the official 2027 figures are released, plan with the 2026 numbers above.

How to decide in 3 steps

1. Find your marginal tax bracket. Our take-home pay calculator uses 2026 brackets. In the 10% or 12% bracket, lean Roth. In the 32% bracket or higher, lean traditional (if you can deduct it).
2. Check your eligibility. Compare your modified AGI with the Roth and deduction ranges. If you can’t deduct a traditional contribution but can contribute to a Roth, the Roth is usually the clear pick.
3. Look at your whole picture. If nearly all your savings are pre-tax, add Roth money for balance. If you need to lower AGI this year, use traditional. Not sure? Split it.

Then open the account at a low-cost brokerage, set up an automatic monthly contribution ($625 a month maxes out a $7,500 limit) and choose your investments. For year-end moves that pair well with IRA contributions, see our 2026 year-end tax planning guide.
