Roth IRA vs. Traditional IRA: How to Choose

Choosing between a Roth IRA vs. traditional IRA is one of the first decisions many savers face when they open an individual retirement account. Both accounts let your investments grow without yearly taxes on gains, and both share the same annual contribution cap. The real difference is timing: one gives you a possible tax break today, while the other can give you tax-free income later.

This guide walks through how each account is taxed, who can contribute, what the current limits are, and how withdrawals work. You will also find a side-by-side comparison table and a simple hypothetical example that shows why your future tax rate matters so much. Nothing here is personal advice, but it should help you ask the right questions before you decide.

What Each Account Does

A traditional IRA is built around the idea of deferring taxes. If you qualify, the money you put in can be deducted on your tax return for the year you contribute. Your balance grows without annual tax on dividends or gains. When you take money out in retirement, the deductible contributions and all of the earnings are taxed as ordinary income.

A Roth IRA flips that order. You contribute money you have already paid tax on, so there is no deduction up front. In exchange, a qualified distribution later on is completely free of federal income tax, including all of the growth. For many people, that makes a Roth feel like paying the tax bill on the seed instead of the harvest.

Both accounts require taxable compensation, such as wages or self-employment income. If you file a joint return, a spouse’s compensation can count. Neither account has an upper age limit for making contributions anymore; the IRS notes the old age 70½ cutoff for traditional IRA contributions ended in 2020.

Roth IRA vs. Traditional IRA: Side-by-Side Comparison

The table below summarizes the main rules. Dollar figures are for tax year 2026, as of October 2026.

Feature	Traditional IRA	Roth IRA
Tax treatment of contributions	May be deductible, depending on income and workplace plan coverage	Never deductible
Tax on growth while invested	None while the money stays in the account	None while the money stays in the account
Tax on withdrawals	Deductible contributions and earnings taxed as ordinary income	Qualified distributions are tax-free
2026 contribution limit	$7,500 combined across all IRAs ($8,600 if 50 or older)	Same combined limit
Income limit to contribute	None, but deductibility can phase out	Yes; ability to contribute phases out at higher incomes
Required minimum distributions	Yes, generally starting at age 73	None for the original owner during life
Early withdrawal penalty	10% additional tax before 59½ unless an exception applies	10% additional tax may apply to taxable portions before 59½

Contribution Limits and Income Rules (as of October 2026)

For 2026, the IRS set the IRA contribution limit at $7,500, up from $7,000 in 2025. If you are 50 or older, the catch-up amount is $1,100, so your total can reach $8,600. This is a single limit shared by all of your IRAs. You cannot put $7,500 into a traditional IRA and another $7,500 into a Roth in the same year.

Roth IRA income phase-outs for 2026

Single or head of household: modified AGI of $153,000 to $168,000
Married filing jointly: $242,000 to $252,000
Married filing separately: $0 to $10,000

Inside each range, the amount you are allowed to contribute shrinks. Above the top of the range, you cannot make a direct Roth contribution for that year.

Traditional IRA deduction phase-outs for 2026

Anyone with compensation can contribute to a traditional IRA, but the deduction can be limited if you or your spouse are covered by a retirement plan at work:

Single, covered by a workplace plan: $81,000 to $91,000
Married filing jointly, contributing spouse covered: $129,000 to $149,000
Married filing jointly, you are not covered but your spouse is: $242,000 to $252,000
Married filing separately, covered: $0 to $10,000

If neither you nor your spouse has a workplace plan, the deduction is not reduced by these ranges. Contributions for a given year are generally due by your tax filing deadline, not counting extensions. These numbers are adjusted for inflation, so check the IRS figures each year before you contribute.

How Withdrawals Are Taxed

With a traditional IRA, withdrawals are generally taxable income in the year you take them. If you ever made nondeductible contributions, part of each withdrawal may come out tax-free, which is tracked on IRS Form 8606.

A Roth IRA distribution is tax-free when it is “qualified.” Under IRS rules, that means two tests are met. First, the withdrawal happens after a five-year period that starts with the first year you contributed to any Roth IRA. Second, you are at least 59½, the distribution is made after your death, you are disabled, or the money goes toward qualified first-time homebuyer expenses.

For both account types, the IRS may apply a 10% additional tax to taxable amounts withdrawn before age 59½, unless an exception applies. That is why most people treat IRAs as long-term money rather than an emergency fund.

Required Minimum Distributions

A traditional IRA eventually forces you to start taking money out. Under current IRS guidance, owners generally must begin required minimum distributions (RMDs) at age 73, with the first one due by April 1 of the following year. Each withdrawal is taxable, which can push up your income in your seventies whether you need the cash or not.

Roth IRAs do not require withdrawals while the original owner is alive. That gives Roth savers more control over when, and whether, they tap the account. Beneficiaries who inherit a Roth IRA are subject to distribution rules, however.

A Hypothetical Example: Why Your Future Tax Rate Matters

Imagine two savers, Alex and Jordan, who each set aside $7,500 of pre-tax earnings. To keep the math simple, assume a hypothetical flat 20% tax rate today and that each account grows four times over before retirement. These are made-up figures for illustration only, not a forecast of investment returns.

Alex (traditional IRA): deducts the full $7,500, so all of it goes into the account. It grows to $30,000. At withdrawal, a 20% tax leaves $24,000.
Jordan (Roth IRA): pays 20% tax first, leaving $6,000 to invest. It grows to $24,000, and the qualified withdrawal is tax-free: $24,000.

When the tax rate is the same at both ends, the results match. Now change one assumption. If Alex’s tax rate in retirement is a hypothetical 25%, the traditional IRA nets only $22,500, and the Roth comes out ahead. If Alex’s rate drops to 15%, the traditional IRA nets $25,500 and wins. The core question, then, is whether you expect your tax rate to be higher or lower when you withdraw.

How to Decide Which One Fits You

There is no universal winner, but a few patterns can guide your thinking:

A Roth may appeal if you are early in your career, currently in a lower bracket, expect higher income later, or value tax-free income and freedom from RMDs.
A traditional IRA may appeal if you are in your peak earning years, can take the full deduction, and expect lower taxable income after you stop working.
Splitting contributions between both types is allowed within the combined limit. Some people use this to hedge against uncertainty about future tax rates.
Income limits may decide for you. If your income is above the Roth phase-out range, a direct Roth contribution is not available that year.

It also helps to look at the full picture. Social Security, pensions, and workplace plans all affect your taxable income in retirement. Our guide to building retirement income that lasts covers how these pieces fit together, and our overview of investing for retirement explains how to choose what to hold inside the account. Remember that the IRA is only the container; the investments you pick inside it carry their own risk, and their value can go down as well as up.

Frequently Asked Questions

Can I have both a Roth IRA and a traditional IRA?

Yes. You can own both, but your total contributions across all IRAs cannot exceed the annual limit, which is $7,500 for 2026 ($8,600 if you are 50 or older), as of October 2026.

Can I contribute to an IRA if I have a 401(k) at work?

Yes. Workplace plan coverage does not stop you from contributing. It can, however, reduce or eliminate the deduction for traditional IRA contributions depending on your income. Roth eligibility depends on your modified AGI, not on plan coverage.

Is there an age limit for contributing?

No. As long as you or your spouse (if filing jointly) has taxable compensation, you can contribute to either account at any age.

Do Roth IRAs have required minimum distributions?

Not for the original owner during their lifetime. Traditional IRAs do, generally starting at age 73. For a deeper look at stretching your savings, see strategies to make your retirement savings last.

Bottom Line

The Roth IRA vs. traditional IRA choice comes down to when you want to pay tax. A traditional IRA may lower your tax bill now, while a Roth can provide tax-free income and more flexibility later. Check the current IRS limits, consider where your income is likely headed, and remember that you can use both. If your situation is complex, a qualified tax professional can help you weigh the details.
