Choosing between a Roth IRA and a traditional IRA is one of the most common retirement planning questions. If you are also saving for education, see our 529 plan guide. Both accounts offer tax advantages that help your money grow faster than in a regular taxable account. The difference is when you get the tax break — now, or later.
This guide explains how each account works, the key differences, and how to decide which one is right for your situation in 2026.
How a Traditional IRA Works
A traditional IRA allows you to make contributions that may be tax-deductible, depending on your income and whether you have access to a workplace retirement plan. The money grows tax-deferred, meaning you do not pay taxes on dividends, interest, or capital gains while the money stays in the account.
When you withdraw money in retirement, you pay ordinary income tax on the full withdrawal amount. You must start taking required minimum distributions (RMDs) starting at age 73.
The tax deduction upfront is the traditional IRA’s main advantage. If you are in a high tax bracket today and expect to be in a lower bracket in retirement, you benefit by taking the deduction now and paying taxes at the lower rate later.
How a Roth IRA Works
A Roth IRA is funded with after-tax dollars — you get no tax deduction in the year you contribute. The money grows tax-free, and qualified withdrawals in retirement are completely tax-free, including the earnings. There are no required minimum distributions during your lifetime.
The Roth IRA’s main advantage is tax-free growth and tax-free income in retirement. If you expect to be in a higher tax bracket in retirement than you are today — or if you simply want tax-free flexibility in retirement — the Roth is typically the better choice.
Contribution Limits in 2026
The contribution limit for both Roth and traditional IRAs is $7,000 per year if you are under age 50. If you are 50 or older, you can contribute an additional $1,000 catch-up contribution, for a total of $8,000.
This limit applies to your combined contributions across all IRAs. You cannot contribute $7,000 to a Roth and $7,000 to a traditional IRA in the same year — the total across both must be $7,000 or less.
Income Limits to Know
Roth IRA eligibility phases out at higher incomes. In 2026, single filers can contribute the full amount with a modified adjusted gross income (MAGI) below $146,000. Contributions phase out between $146,000 and $161,000 and are eliminated above $161,000.
For married filing jointly, the phase-out range is $230,000 to $240,000. Above $240,000, Roth contributions are not allowed directly (though the backdoor Roth IRA strategy remains an option for high earners).
Traditional IRA contributions are always allowed regardless of income, but the tax deductibility phases out for those covered by a workplace retirement plan with higher incomes.
Roth vs. Traditional: The Core Decision
The simplest framework: if you expect your tax rate to be higher in retirement than it is now, choose a Roth. If you expect your tax rate to be lower in retirement, choose a traditional IRA and take the deduction today.
Early-career workers in low tax brackets almost always benefit from Roth contributions. The tax rate they pay today is likely the lowest they will ever pay, and decades of tax-free growth in a Roth can be enormously valuable.
Mid-career workers in peak earning years may benefit more from a traditional IRA deduction, particularly if they are in the 24% or 32% marginal bracket and expect to have more modest taxable income in retirement.
High earners who cannot contribute directly to a Roth can use the backdoor Roth strategy: make a non-deductible traditional IRA contribution and then convert it to a Roth. This requires careful attention to the pro-rata rule if you have other pre-tax IRA money.
Key Advantages of the Roth IRA
Tax-free income in retirement is more valuable than it sounds. It gives you flexibility in managing your tax bracket in retirement, reduces Medicare premium surcharges for high-income retirees, and is not subject to RMDs that would otherwise force taxable income you may not need.
The Roth IRA also allows penalty-free withdrawal of contributions (not earnings) at any time for any reason. This makes it a useful emergency backup, though it should not replace a dedicated emergency fund.
The Bottom Line
For most people under 40 in low-to-moderate tax brackets, the Roth IRA is the better choice. For higher earners or those in their peak earning years who need the current-year tax deduction, the traditional IRA may make more sense. When in doubt, split contributions between both — many financial advisors recommend tax diversification in retirement accounts rather than putting everything into one type.
