Roth IRA vs. Traditional IRA: Which One Fits You?

A Roth IRA and a Traditional IRA are both Individual Retirement Arrangements — accounts you open yourself that let investments grow with tax advantages. The core difference is a single question: do you want your tax break now, or later? Everything else flows from that.

The difference in one table

2026 contribution limits (IRS)

For 2026, the IRS contribution limit is $7,500 if you are under 50, and $8,600 if you are 50 or older (the extra $1,100 is the catch-up contribution). Two rules people miss: first, the limit is combined across all your IRAs — you cannot put $7,500 in a Roth and another $7,500 in a Traditional in the same year. Second, you cannot contribute more than your earned income for the year.

2026 Roth IRA income phase-outs

Eligibility to contribute directly to a Roth IRA phases out with modified adjusted gross income. For 2026: single filers phase out between $153,000 and $168,000; married couples filing jointly phase out between $242,000 and $252,000. Above the top of the range, direct Roth contributions are not allowed (some higher earners use a “backdoor Roth” conversion strategy — a more advanced move worth professional advice).

Tax now vs. tax later: a worked example

Suppose you contribute $6,000 and it grows to $18,000 by retirement. With a Traditional IRA, if you deducted the contribution at a 22% tax rate, you saved $1,320 in tax today — but you will owe income tax on the full $18,000 as you withdraw it. With a Roth IRA, you got no deduction, but the entire $18,000 comes out tax-free if the withdrawal is qualified. The Roth wins if your tax rate in retirement is higher than today’s; the Traditional wins if it is lower. When the rates are equal, the two are mathematically very close.

A simple way to choose

• Early career or a low-income year? Your current tax rate is probably the lowest it will ever be — that tilts toward Roth.
• Peak earning years? A Traditional deduction at a high rate is valuable — that tilts toward Traditional (if you can deduct it).
• Want flexibility? Roth contributions (not earnings) can be withdrawn anytime without tax or penalty, though raiding retirement savings is still a last resort.
• Already have a big pre-tax 401(k)? Adding Roth money diversifies your future tax situation.
• Not sure? Many savers split contributions, or do Roth now and revisit later.

Remember that an IRA is a container, not an investment. After contributing, you still choose what to hold inside it — for many beginners that is a diversified index fund (see Index Funds vs. Individual Stocks). And an IRA complements rather than replaces a workplace plan: if your employer matches 401(k) contributions, capture the full match first, then consider an IRA. Our 401(k) guide explains the order of operations.
