Traditional IRA vs. Roth IRA — What’s the Difference?
Traditional IRA and Roth IRA are both individual retirement accounts with significant tax advantages — but they work in opposite directions. The core question is whether you pay taxes now or later. Understanding which account fits your situation can make a meaningful difference in how much you keep in retirement.
Key Takeaways
- Traditional IRA contributions may be tax-deductible; Roth IRA contributions are made with after-tax dollars and are never deductible.
- Traditional IRA withdrawals are taxed as ordinary income; qualified Roth IRA withdrawals are entirely tax-free.
- Roth IRA contributions are subject to income limits based on MAGI; Traditional IRA contributions have no income limit, though the deduction may phase out.
- Traditional IRAs require minimum distributions (RMDs) starting at age 73 or 75, depending on your birth year; Roth IRAs have no RMD requirement during the original owner’s lifetime.
- Both accounts share the same annual contribution limit — the combined total across all your IRAs cannot exceed the IRS limit for the year.
- Roth IRA original contributions (not earnings) can be withdrawn at any time without tax or penalty; Traditional IRA withdrawals before age 59½ generally trigger a 10% early withdrawal penalty.

1. What Is an IRA?
An IRA — Individual Retirement Account — is a personal retirement savings account that you open and manage independently, separate from any workplace plan like a 401(k). IRAs are available through banks, brokerage firms, credit unions, and insurance companies.
The two most common types are the Traditional IRA and the Roth IRA. Both grow tax-advantaged over time, but the timing of the tax benefit is fundamentally different. A third type — the SEP IRA — is designed for self-employed individuals and small business owners and works differently from the two covered here.
You can contribute to an IRA even if you already participate in a 401(k) or other employer-sponsored retirement plan. However, your ability to deduct Traditional IRA contributions — or contribute to a Roth IRA at all — depends on your income and filing status.
2. How a Traditional IRA Works
A Traditional IRA allows you to contribute pre-tax or after-tax dollars, with the possibility of deducting contributions from your taxable income. Inside the account, your investments grow tax-deferred — meaning you owe no tax on dividends, interest, or capital gains until you take money out.
Tax Deduction: Three Scenarios
Whether your Traditional IRA contribution is deductible depends on two factors: your MAGI and whether you (or your spouse) are covered by a retirement plan at work.
| Situation | Deductibility |
|---|---|
| Neither you nor your spouse has a workplace retirement plan | Fully deductible regardless of income |
| You are covered by a workplace retirement plan | Deduction phases out based on your MAGI |
| You are not covered, but your spouse is covered by a workplace plan | Deduction phases out at a higher, separate MAGI range |
If your contribution is not deductible, you can still make a nondeductible Traditional IRA contribution. The money goes in after-tax, and you track this using IRS Form 8606. This distinction matters later — nondeductible contributions are not taxed again when withdrawn, but the earnings are.
Withdrawals
Distributions from a Traditional IRA are taxed as ordinary income in the year you receive them. Withdrawals before age 59½ generally trigger a 10% early withdrawal penalty on top of regular income tax, unless an exception applies (such as disability, first-time home purchase up to $10,000, or qualified education expenses).
Required Minimum Distributions (RMDs)
Traditional IRAs require you to begin taking distributions once you reach a certain age. Under the SECURE 2.0 Act, the RMD starting age depends on your birth year: age 73 for those born between 1951 and 1959, and age 75 for those born in 1960 or later. Failing to take a required distribution results in a substantial excise tax on the shortfall.
3. How a Roth IRA Works
A Roth IRA is funded with after-tax dollars. You receive no upfront deduction. In exchange, your money grows tax-free, and qualified withdrawals — including all earnings — are completely tax-free.
Qualified Distributions
A Roth IRA withdrawal is “qualified” — and therefore tax-free and penalty-free — when two conditions are both met:
- The account has been open for at least five tax years (measured from January 1 of the first year you contributed to any Roth IRA), and
- You are at least age 59½, or the distribution is due to death, disability, or a first-time home purchase (lifetime limit of $10,000).
Important: The five-year clock starts on January 1 of the first tax year for which you made any Roth IRA contribution — not from the date of each individual contribution. If you open a Roth IRA in December, the five-year period begins January 1 of that same year.
Withdrawing Contributions vs. Earnings
Roth IRA contributions — the dollars you actually put in — can be withdrawn at any time without tax or penalty, because you already paid tax on them. Only the earnings portion is subject to the qualified distribution rules above. This ordering rule (contributions first, then earnings) is a key feature that distinguishes the Roth from the Traditional IRA.
No RMDs During Your Lifetime
Unlike a Traditional IRA, a Roth IRA has no required minimum distributions while the original owner is alive. This makes the Roth IRA particularly effective for long-term wealth accumulation and estate planning — the account can continue growing tax-free indefinitely.
Income Limits
Your ability to contribute directly to a Roth IRA is limited by your MAGI. As income rises within the phase-out range, your allowable contribution decreases. Above the upper threshold, direct contributions are not permitted. (See Section 5 for current phase-out figures.)
4. Side-by-Side Comparison
| Feature | Traditional IRA | Roth IRA |
|---|---|---|
| Contribution Type | Pre-tax or after-tax (nondeductible) | After-tax only |
| Tax Deduction | Possible (income and workplace plan rules apply) | Never deductible |
| Growth | Tax-deferred | Tax-free |
| Tax on Withdrawals | Ordinary income tax on all deductible contributions and earnings | Tax-free on qualified distributions |
| Income Limit to Contribute | None | Yes — MAGI-based phase-out |
| RMD Required | Yes — starting at age 73 or 75 | No (original owner’s lifetime) |
| Early Withdrawal (before 59½) | 10% penalty + income tax (exceptions apply) | Contributions: penalty-free anytime; earnings: 10% penalty if not qualified |
| Best Fit | Expect lower tax rate in retirement than today | Expect higher tax rate in retirement than today |
5. Contribution Limits and Income Phase-Outs
Annual Contribution Limit
The IRS sets an annual limit on how much you can contribute across all of your Traditional and Roth IRAs combined. The limit applies per person, not per account. If you have both a Traditional IRA and a Roth IRA, your total contributions to both cannot exceed the limit for the year.
| Age | Annual Contribution Limit |
|---|---|
| Under 50 | $7,500 |
| Age 50 and older (catch-up) | $8,600 |
Your contribution cannot exceed your taxable compensation for the year. These limits are adjusted periodically by the IRS for inflation.
Traditional IRA Deduction Phase-Out Ranges
If you or your spouse is covered by a workplace retirement plan, your Traditional IRA deduction may be reduced or eliminated based on MAGI:
| Filing Status / Situation | MAGI Phase-Out Range |
|---|---|
| Single or HOH — covered by workplace plan | $81,000 – $91,000 |
| MFJ — contributing spouse covered by workplace plan | $129,000 – $149,000 |
| MFJ — contributing spouse not covered, but the other spouse is | $242,000 – $252,000 |
| MFS — covered by workplace plan | $0 – $10,000 |
Above the upper limit of the range, no deduction is allowed — but you can still make a nondeductible Traditional IRA contribution and track it on Form 8606.
Roth IRA Contribution Phase-Out Ranges
Roth IRA eligibility phases out based on MAGI. Above the upper threshold, direct contributions are not permitted:
| Filing Status | MAGI Phase-Out Range |
|---|---|
| Single or Head of Household | $153,000 – $168,000 |
| Married Filing Jointly | $242,000 – $252,000 |
| Married Filing Separately | $0 – $10,000 |
Backdoor Roth IRA: If your income exceeds the Roth contribution limit, one strategy is to contribute to a nondeductible Traditional IRA and then convert it to a Roth IRA. This approach — commonly called a “Backdoor Roth” — is legal but requires careful attention to the Pro-Rata Rule. If you have existing balances in any Traditional IRA, SEP IRA, or SIMPLE IRA, those balances are factored into the taxable portion of the conversion. The calculation is not limited to the IRA you are converting — it applies across all pre-tax IRA balances you hold.
6. Which Should You Choose?
The decision between a Traditional IRA and a Roth IRA generally comes down to one question: will your tax rate be higher now or in retirement?
| Your Situation | Likely Better Choice | Reason |
|---|---|---|
| Current tax rate is higher than expected retirement rate | Traditional IRA | Deduct now at a higher rate; pay tax later at a lower rate |
| Current tax rate is lower than expected retirement rate | Roth IRA | Pay tax now at a lower rate; withdraw tax-free later |
| Future tax rate is uncertain | Split contributions between both | Diversifies your tax exposure in retirement |
| Income exceeds Roth contribution limit | Backdoor Roth (if applicable) | Indirect path to Roth via nondeductible Traditional IRA conversion |
| Planning to pass assets to heirs | Roth IRA | No RMDs allow the account to continue growing tax-free |
Note that your “retirement tax rate” is not simply your current bracket. It includes Social Security income (which may be partially taxable), pension payments, rental income, RMDs from other accounts, and any other taxable income sources. Many retirees have more taxable income than they expect, which is why the decision deserves careful analysis rather than a simple rule of thumb.
EA Insight
The most common mistake I see is treating the Roth IRA as the automatic right answer. “I’m in a low bracket now, so Roth is always better” is a reasonable starting point — but it ignores what retirement income actually looks like. Once you factor in Social Security, RMDs from a 401(k), and other sources, many retirees find themselves in a higher tax bracket than they expected. Choosing between Traditional and Roth requires projecting your full retirement income picture, not just comparing today’s bracket to a guess.
The Backdoor Roth is a legitimate and widely used strategy for high-income earners, but the Pro-Rata Rule trips people up constantly. The calculation is not limited to the IRA you are converting — it applies to the total balance across all your pre-tax IRA accounts, including SEP IRAs and SIMPLE IRAs. If you have substantial pre-tax IRA balances, a significant portion of the conversion will be taxable, which may reduce the strategy’s benefit. This is one area where I strongly recommend running the numbers with a tax professional before proceeding.
On the Roth IRA flexibility point: yes, original contributions can be withdrawn at any time without penalty. But I caution clients against treating the Roth as a backup emergency fund. Every dollar withdrawn early is a dollar that loses decades of tax-free compounding. The flexibility is real — but using it should be a last resort, not a plan.
Frequently Asked Questions
Can I contribute to both a Traditional IRA and a Roth IRA in the same year?
Yes — as long as your total contributions to all IRAs combined do not exceed the annual limit for the year. For example, you could split the limit between both accounts in any proportion. The combined total cap applies regardless of how many IRA accounts you hold.
What happens if I contribute to a Roth IRA but my income is over the limit?
Excess contributions to a Roth IRA are subject to a 6% excise tax for each year the excess remains in the account. To avoid the penalty, you must withdraw the excess contribution — and any earnings on it — by your tax filing deadline (including extensions). Alternatively, you can recharacterize the contribution as a nondeductible Traditional IRA contribution.
How does the Roth IRA five-year rule actually work?
The five-year clock starts on January 1 of the first tax year for which you made any Roth IRA contribution — not from the date of each individual deposit. If you contribute for the first time in November, the clock starts January 1 of that same year. This means you do not restart the five-year period with each new contribution. However, a Roth IRA conversion has its own separate five-year clock for determining whether the converted amount can be withdrawn penalty-free before age 59½.
Can a non-working spouse contribute to an IRA?
Yes. Under the Spousal IRA rules, a non-working spouse can contribute to a Traditional or Roth IRA based on the working spouse’s earned income, as long as the couple files a joint return and has sufficient combined earned income. The non-working spouse’s contribution limit is the same as for any other IRA contributor — subject to Roth income limits if contributing to a Roth IRA.
Can I convert a Traditional IRA to a Roth IRA?
Yes. A Roth conversion allows you to move funds from a Traditional IRA into a Roth IRA. The converted amount is added to your taxable income in the year of conversion. There are no income limits on conversions — anyone can convert regardless of MAGI. However, the full tax impact of the conversion should be evaluated before proceeding, especially if you have large pre-tax IRA balances.
I have a 401(k) at work. Can I still contribute to an IRA?
Yes. Having a 401(k) or other workplace retirement plan does not prevent you from contributing to a Traditional or Roth IRA. However, if you are covered by a workplace plan, your ability to deduct Traditional IRA contributions may be limited based on your MAGI. Roth IRA eligibility is also subject to MAGI limits, regardless of workplace plan participation.
