Key Takeaways
Option A
Traditional IRA
The tax-deferred account that reduces your taxable income today.
Best for: People who expect to be in a lower tax bracket in retirement than they are now.
Option B
Roth IRA
The tax-free growth account funded with after-tax dollars.
Best for: People who expect to be in the same or higher tax bracket in retirement.
If you want to lower your tax bill this year
Traditional IRA
Contributions to a Traditional IRA may be deductible from your taxable income in the year you make them, depending on your income and whether you have a workplace retirement plan.
If you expect your income and tax rate to rise over time
Roth IRA
Paying tax now at a potentially lower rate means your future withdrawals will be tax-free, which can be more valuable if your tax bracket rises by retirement.
If you want flexibility to access contributions before retirement
Roth IRA
With a Roth IRA, you can withdraw your original contributions (not earnings) at any time without penalty, giving you more financial flexibility.
If you want to avoid mandatory withdrawals later in life
Roth IRA
Roth IRAs do not require distributions during the account owner's lifetime, so your balance can continue to grow if you do not need the funds in early retirement.
If you earn too much to contribute to a Roth IRA
Traditional IRA
Traditional IRAs have no income ceiling on contributions, making them accessible to higher earners who are phased out of Roth IRA eligibility.
What a Traditional IRA and a Roth IRA have in common
Both account types are Individual Retirement Arrangements (IRAs), a category of tax-advantaged account defined by the IRS to encourage long-term retirement saving. You open and manage both independently of an employer, which makes them useful whether or not you have access to a workplace plan such as a 401(k). For background on how retirement accounts fit into a broader savings picture, see Retirement Accounts Explained.
The IRS sets a shared annual contribution limit that applies across all your IRA accounts combined. For 2024, that limit is $7,000 per year, or $8,000 if you are age 50 or older (the extra $1,000 is called a catch-up contribution). You must have earned income at least equal to the amount you contribute, and you cannot contribute more than your actual earned income for the year.
Within both account types, your money can be invested in assets such as stocks, bonds, and mutual funds. The accounts themselves do not produce returns; the investments held inside them do. Past performance of any investment does not guarantee future results.
The core difference: when you pay tax
The single most important distinction between the two accounts is timing. A Traditional IRA is funded with pre-tax or tax-deductible dollars, meaning you may get a tax deduction now and pay income tax when you withdraw the money in retirement. A Roth IRA is funded with after-tax dollars, meaning no deduction today, but qualified withdrawals in retirement are tax-free.
| Criterion | Traditional IRA | Roth IRA |
|---|---|---|
| Tax treatment of contributions | May be tax-deductible now | No deduction; paid with after-tax dollars |
| Tax treatment of withdrawals | Taxed as ordinary income in retirement | Qualified withdrawals are tax-free |
| Income limit to contribute | None (deductibility may be limited) | Phase-out applies above IRS thresholds |
| Early withdrawal of contributions | Taxed and penalized | Contributions withdrawable any time, penalty-free |
| Required minimum distributions | Required starting at age 73 | None during owner's lifetime |
| 2024 contribution limit | $7,000 ($8,000 if age 50+) | $7,000 ($8,000 if age 50+) |
Which arrangement is more valuable depends heavily on your current tax rate compared with your expected tax rate in retirement. If you are early in your career and expect your income to grow significantly, paying tax now (Roth) may cost less overall. If you are in a high-earning period now and expect a lower income in retirement, deferring tax (Traditional) may work in your favor. Neither outcome is guaranteed, because tax law can change.
Income limits and eligibility rules
Anyone with earned income can contribute to a Traditional IRA, but the ability to deduct that contribution depends on whether you (or your spouse) participate in a workplace retirement plan and how much you earn. If neither you nor your spouse has a workplace plan, contributions are fully deductible regardless of income. When a workplace plan is involved, the deduction phases out above certain income thresholds that the IRS adjusts periodically.
Roth IRA eligibility works differently. You can only contribute the full amount if your modified adjusted gross income (MAGI) falls below a threshold set by the IRS. Above that threshold, the allowed contribution phases down, and above a higher ceiling, you cannot contribute to a Roth IRA at all for that year. For 2024, the phase-out range for single filers starts at $146,000 and for married filing jointly starts at $230,000.
If your income exceeds Roth IRA limits, a Traditional IRA remains available as an alternative. For a comparison of IRAs against employer-sponsored options, see 401(k) vs IRA.
Withdrawals, penalties, and required distributions
Both account types allow penalty-free withdrawals starting at age 59 and a half. Withdrawals before that age generally trigger a 10% early withdrawal penalty on top of any tax owed, with limited exceptions such as first-time home purchases or certain medical expenses.
With a Traditional IRA, every dollar you withdraw in retirement is taxed as ordinary income. This includes both your original contributions and all growth.
With a Roth IRA, qualified withdrawals (taken after age 59 and a half, from an account at least five years old) are completely tax-free, including growth. You can also withdraw your original contributions at any time, at any age, without tax or penalty, because you already paid tax on that money. Withdrawing earnings early, however, may still trigger penalties.
Traditional IRAs require you to begin taking required minimum distributions (RMDs) starting at age 73 under current IRS rules. These mandatory withdrawals can increase your taxable income in retirement even if you do not need the money. Roth IRAs have no RMD requirement during the account owner's lifetime, so the balance can remain invested.
The five-year rule for Roth IRAs
To receive tax-free withdrawals of earnings from a Roth IRA, the account must have been open for at least five tax years and you must be age 59 and a half or older. The five-year clock starts on January 1 of the first tax year for which you made a Roth IRA contribution. Opening an account earlier, even with a small contribution, starts that clock sooner.
How to approach the decision
A useful starting point is to estimate whether your tax rate is likely to be higher or lower in retirement than it is today. Younger savers with lower current incomes often lean toward a Roth IRA. Those in a higher-income period may find a Traditional IRA deduction more valuable right now.
If you are unsure, some people contribute to both types over time, adjusting the split as their income changes. Contributions to both in the same year are allowed, as long as the combined total does not exceed the annual IRS limit.
Tax rules are complex and personal. A licensed financial adviser or tax professional can help you apply income thresholds, deductibility rules, and withdrawal strategies to your specific situation before you commit to a direction.
