Like the 401(k) version of this decision, choosing between a traditional and Roth IRA comes down largely to whether you'd rather get a tax break now or tax-free withdrawals later. But IRAs have their own specific rules — particularly around income eligibility — that make this a genuinely separate decision from the 401(k) equivalent.
The core tax tradeoff, briefly
Traditional IRA contributions may be tax-deductible in the year you contribute (subject to income limits if you or a spouse is covered by a workplace retirement plan), with withdrawals in retirement taxed as ordinary income. Roth IRA contributions are made with after-tax dollars — no upfront deduction — but qualified withdrawals in retirement, including growth, are completely tax-free.
Income limits: the detail that changes everything
Roth IRA contributions phase out entirely above certain income thresholds, which change periodically and are worth checking directly at IRS.gov rather than relying on a specific number that may be outdated. Traditional IRA contributions have no income limit for the contribution itself, but the tax deductibility phases out at certain income levels if you're covered by a workplace plan — meaning a traditional IRA contribution can sometimes be non-deductible, which changes the math considerably.
Contribution limits and flexibility
IRAs generally have a combined annual contribution limit across both traditional and Roth accounts (the specific dollar figure changes periodically with inflation adjustments — check current limits at IRS.gov). Roth IRAs also offer a notable flexibility: contributions (though not earnings) can generally be withdrawn at any time without penalty, since they were already taxed — a feature traditional IRAs and most 401(k)s don't share.
Required distributions
Traditional IRAs are subject to required minimum distributions (RMDs) starting at a certain age, forcing withdrawals whether or not the money is needed. Roth IRAs, for the original account owner, generally have no RMD requirement during their lifetime, offering more flexibility in retirement income planning and estate planning.
A practical way to decide
- Check income eligibility first — if income is above the Roth phase-out range, the traditional IRA (or backdoor Roth strategy) becomes the relevant conversation.
- Consider current versus expected future tax bracket, similar to the 401(k) decision — lower current bracket generally favors Roth, higher current bracket favors traditional.
- Value the flexibility of Roth contributions if there's a reasonable chance the money might be needed before retirement — though using retirement funds early is generally discouraged as a first resort.
