Understand how traditional and Roth IRAs differ in taxes, contributions, and withdrawals. Compare which fits your retirement
Last Updated: October 9, 2026
Understanding traditional vs roth ira comes down to when you pay taxes. With a traditional IRA, you may deduct contributions from your taxable income in the year you make them, reducing your current tax bill, and the money grows tax-deferred until you withdraw in retirement. A Roth IRA flips this: contributions are made with after-tax dollars, so you get no immediate deduction, but qualified withdrawals are entirely tax-free.
We help families choose the account type that aligns with their expected tax situation in retirement.
The choice between traditional and Roth IRA isn’t just about current tax brackets. Someone expecting lower income in retirement may benefit more from a traditional IRA’s upfront deduction, while someone anticipating higher taxes later might prefer the Roth’s tax-free growth and withdrawals.
A traditional IRA lets you deduct contributions on your tax return, but only if you meet certain eligibility requirements. The rules hinge on two questions: whether you (or your spouse) are covered by a workplace retirement plan, and how much modified adjusted gross income (MAGI) you report.
If neither you nor your spouse is covered by an employer plan like a 401(k), 403(b), or government plan, there is no income limit on the deduction. You can deduct your full contribution regardless of earnings, up to the annual contribution limit.
When you are covered by an employer plan, the deduction phases out over a MAGI range that depends on your filing status. The IRS publishes these ranges each year and adjusts them for inflation, so confirm the current figures in IRS Publication 590-A before you file. The structure works like this:
Within the phase-out range, your deductible amount is reduced proportionally. Once your MAGI reaches the top of the band, your deduction is eliminated entirely, though you can still make nondeductible traditional IRA contributions.
This is the case most people get wrong. If you personally are not covered by a workplace plan but your spouse is, you can still deduct your traditional IRA contribution, subject to a separate (usually higher) MAGI phase-out range. Your deduction eligibility depends on whether you have coverage, not just whether your spouse does.
Suppose a married couple files jointly. One spouse is covered by a 401(k); the other is not. Whether the non-covered spouse’s full contribution is fully deductible, partially deductible, or nondeductible depends on where the couple’s MAGI falls within the phase-out band for a non-covered spouse. Households near the top of the band often find only a fraction is deductible, changing the after-tax math compared with a Roth contribution.
If your deduction is reduced or eliminated, you can still make a nondeductible traditional IRA contribution. That contribution creates basis in the account, so a portion of future withdrawals may be tax-free when you file Form 8606 to track it, a detail that matters if you later convert or withdraw.
The tax-deferred growth inside a traditional IRA remains powerful regardless of deductibility: earnings compound without annual tax drag, and you only pay taxes when you withdraw, potentially decades later. The value of the upfront deduction depends on your marginal rate today versus your expected rate in retirement.
Roth IRA contributions are made with after-tax dollars, so you get no immediate deduction. The real benefit emerges over time: all investment earnings grow tax-free, and qualified withdrawals are completely tax-free.
The Roth IRA’s tax-free growth is its defining feature: unlike a traditional IRA, a Roth’s earnings never face federal income tax if you follow the rules.
Roth contributions also offer flexibility traditional IRAs don’t: you can withdraw your contributions (not earnings) at any time without penalty or tax.
Roth IRA income limits are more restrictive than traditional IRA rules: your ability to contribute phases out at higher income levels based on modified adjusted gross income.
For 2026, the annual contribution limit for both traditional and Roth IRAs is the same: you can contribute up to a set amount if you have earned income (Retirement topics – IRA contribution limits).
Your earned income determines how much you can contribute: you cannot contribute more than your total earned income for the year, even if the IRS limit is higher. This rule applies equally to traditional and Roth IRAs.
The contribution deadline is typically April 15 of the following year, giving you time to contribute for the previous tax year once you have a better sense of your annual income.
Eligibility for either account type requires earned income: self-employment income, W-2 wages, and other active income count, but investment income, pensions, and Social Security do not.
Traditional IRA withdrawals before age 59½ typically trigger a 10% early withdrawal penalty plus income taxes on the full amount (Retirement topics – Exceptions to tax on early distributions).
Once you reach age 59½, you can withdraw from a traditional IRA without penalty, though you’ll still owe income taxes, making withdrawals part of your taxable income each year.
Traditional IRAs require required minimum distributions starting at age 73 (Retirement topics – Required minimum distributions (RMDs)).
Roth IRAs have no required minimum distributions during your lifetime, giving you full control over when and how much to withdraw, valuable for leaving money to heirs or managing your tax bracket in retirement.
Three mechanisms drive the real-world outcome of the traditional-vs-Roth decision: the pro-rata rule, the five-year clocks, and the way workplace-plan coverage changes your traditional IRA deduction.
A backdoor Roth is a two-step move: contribute to a traditional IRA (nondeductible, since high earners usually cannot deduct), then convert that balance to a Roth. The conversion is taxable only to the extent of pre-tax dollars and earnings converted.
The catch is the pro-rata rule: you cannot convert only your nondeductible contributions. The IRS treats all your traditional, SEP, and SIMPLE IRA balances as one pool and calculates the taxable portion based on the ratio of pre-tax to after-tax dollars across it. A large pre-tax traditional IRA from a former employer can trigger a tax bill far larger than the amount you contributed.
A common workaround is rolling pre-tax IRA money into a current employer’s 401(k) before converting, removing it from the pro-rata calculation. Not all plans accept incoming rollovers, so verify with the plan administrator first.
There are two separate five-year rules, and confusing them is a frequent error:
Having a workplace plan does two things: it can make your traditional IRA contribution nondeductible at higher incomes (see the deduction rules above), and it gives you a second tax-advantaged bucket to fill.
A common pattern among higher earners is to:
Roth 401(k) contributions grow tax-free like a Roth IRA, but they are subject to required minimum distributions at age 73 unless rolled into a Roth IRA.
Choosing between a traditional and Roth IRA depends on your current tax bracket, expected retirement tax bracket, and time horizon.
Your age matters significantly.
Consider your flexibility needs. A Roth IRA offers easier access to contributions in emergencies, while a traditional IRA locks money away until age 59½ without penalty.
Your workplace plan situation affects the decision.

| Account Type | Tax Deduction | Growth | Withdrawals | RMDs | Best For |
| — | — | — | — | — |
| Traditional IRA | Yes (if eligible) | Tax-deferred | Taxable | Required at 73 | Lower future tax bracket |
| Roth IRA | No | Tax-free | Tax-free | None | Higher future tax bracket |
Choosing between a traditional and Roth IRA is one of the most impactful financial decisions you’ll make, since the tax implications compound over decades.
The main difference is when you pay taxes. With a traditional IRA, you may deduct contributions from your current income, reducing your taxes now, but you pay income tax on withdrawals in retirement. With a Roth IRA, you contribute after-tax dollars, so contributions aren’t deductible, but qualified withdrawals are completely tax-free. This means your choice depends on whether you expect to be in a higher or lower tax bracket in retirement.
Yes, you can contribute to both accounts in the same year, but your total contributions across all IRAs cannot exceed the annual limit. For example, if the annual limit is $7,000 and you contribute $4,000 to a traditional IRA, you can only add $3,000 to a Roth IRA that year. Your earned income must also be sufficient to cover the combined contributions.
Traditional IRAs require you to start taking RMDs at age 73, based on your account balance and life expectancy. Roth IRAs have no RMDs during the account holder’s lifetime, allowing your money to grow tax-free longer. This makes Roths attractive if you don’t need the money immediately and want to leave a tax-free inheritance to beneficiaries.
A Roth conversion involves moving money from a traditional IRA to a Roth IRA, which triggers immediate income taxes on the converted amount. It makes sense if you expect higher tax rates in retirement, want to eliminate future RMDs, or plan to pass tax-free wealth to heirs. However, conversions increase your current-year income, which can affect Medicare premiums and other benefits. Evaluate your specific situation with a financial advisor before converting.
