The Core Difference: When You Pay Taxes
Both a Roth IRA and a traditional IRA let you invest money for retirement and grow it without paying taxes on dividends or capital gains each year. The difference is when you pay income tax on the money.
- Traditional IRA: You may get a tax deduction now. You pay taxes when you withdraw money in retirement.
- Roth IRA: No deduction now. You pay taxes on the money before it goes in. Withdrawals in retirement are tax-free.
The question is simple: do you want to pay taxes now or later?
2026 Contribution Limits
The IRA contribution limit in 2026 is $7,000 per year. If you are 50 or older, you can contribute an extra $1,000 (the catch-up contribution), for a total of $8,000.
This limit applies across all your IRAs combined. If you have both a Roth and a traditional IRA, your combined contributions cannot exceed $7,000.
Roth IRA Income Limits in 2026
Not everyone can contribute to a Roth IRA. The ability to contribute phases out at higher income levels:
- Single filers: Full contribution up to $150,000 MAGI; phases out between $150,000 and $165,000
- Married filing jointly: Full contribution up to $236,000 MAGI; phases out between $236,000 and $246,000
If your income exceeds these limits, you cannot contribute directly to a Roth IRA. You may be able to use the backdoor Roth IRA strategy — contributing to a traditional IRA and converting it — if this applies to you.
Traditional IRA Deductibility in 2026
Traditional IRA contributions are tax-deductible only if you meet certain conditions. If neither you nor your spouse has a workplace retirement plan (like a 401(k)), contributions are fully deductible at any income level.
If you or your spouse have access to a 401(k) or similar plan, the deduction phases out at these income levels:
- Single filers covered by a workplace plan: Deductible up to $79,000 MAGI; phases out up to $89,000
- Married filing jointly (covered by a plan): Deductible up to $126,000 MAGI; phases out up to $146,000
If your income is above these limits and you have a workplace plan, traditional IRA contributions are not tax-deductible. In that case, a Roth IRA (if you qualify) is almost always better.
Which Is Better: Roth or Traditional?
The answer comes down to whether your tax rate is higher now or in retirement. There are two general rules:
Choose a Roth IRA if:
- You are in a low tax bracket now and expect to be in a higher one in retirement
- You are early in your career with room to grow your income
- You want tax-free income in retirement with no required minimum distributions
- You might need to access contributions (not earnings) before retirement — Roth contributions can be withdrawn any time without penalty
Choose a traditional IRA if:
- You are in a high tax bracket now and expect to be in a lower one in retirement
- You need the tax deduction this year to reduce your tax bill
- Your income is above the Roth IRA limit
Early Withdrawal Rules
Both account types charge a 10% penalty on early withdrawals (before age 59½), with exceptions. But there is a key difference:
- Roth IRA: You can withdraw your contributions (not earnings) at any time without taxes or penalty. Only the earnings are subject to penalties if withdrawn early.
- Traditional IRA: All withdrawals are subject to income tax and the 10% penalty if taken before 59½ (with exceptions like first-time home purchase, disability, or medical expenses).
Required Minimum Distributions (RMDs)
Traditional IRAs require you to start taking minimum distributions at age 73. These withdrawals are taxed as ordinary income and can push you into a higher tax bracket in retirement.
Roth IRAs have no RMDs during the owner’s lifetime. This makes Roth IRAs powerful for people who do not need the money in retirement and want to pass tax-free assets to heirs.
Can You Have Both?
Yes. You can contribute to both a Roth IRA and a traditional IRA in the same year — as long as your combined contributions do not exceed the annual limit ($7,000 in 2026).
Many financial advisors recommend contributing to a 401(k) first (at least up to the employer match), then a Roth IRA, then back to the 401(k) if you have more to invest.
Bottom Line
For most people in their 20s and 30s who expect their income to rise, the Roth IRA wins. Tax-free retirement income and no RMDs are powerful advantages that compound over decades.
If you are in a high tax bracket now and need the deduction today, the traditional IRA makes more sense. When in doubt, the Roth IRA is the better default for younger investors.
