Both accounts let you invest up to $7,500 in 2026 for retirement, both grow without annual taxes on dividends and gains, and both can hold the same index funds. The difference comes down to one question: do you want to pay income tax on this money now, or later?
That single choice can be worth tens of thousands of dollars over a career, so it’s worth understanding properly. Below, we compare the Roth IRA and the traditional IRA side by side, walk through who each one suits and show how to decide based on your income today and what you expect in retirement.
The short answer
- Roth IRA: You contribute money you’ve already paid tax on. It grows tax-free, and qualified withdrawals in retirement are completely tax-free.
- Traditional IRA: Your contribution may be tax-deductible this year. It grows tax-deferred, and you pay ordinary income tax when you withdraw in retirement.
If you expect to be in a higher tax bracket later than you are now, the Roth usually comes out ahead. If you expect to be in a lower bracket later, the traditional IRA usually wins. Many young professionals early in their careers fall into the first group.
Side-by-side comparison
| Feature | Roth IRA | Traditional IRA |
|---|---|---|
| 2026 contribution limit | $7,500 ($8,600 if 50+) | $7,500 ($8,600 if 50+) |
| Tax break | Tax-free withdrawals in retirement | Possible deduction now |
| Income limit to contribute | Yes (phases out at higher incomes) | No |
| Income limit for the deduction | Not applicable | Yes, if you or your spouse has a workplace plan |
| Withdrawals of contributions | Anytime, tax- and penalty-free | Taxed, plus 10% penalty before 59½ (with exceptions) |
| Required minimum distributions | None during the owner’s lifetime | Yes, starting in your 70s |
| Best for | Lower current tax bracket, long time horizon | Higher current tax bracket |
The $7,500 limit is shared. You can split contributions between a Roth and a traditional IRA, but your combined total can’t exceed the annual limit, and you need at least that much earned income.
2026 income limits you need to know
Roth IRA contribution limits
Your ability to contribute directly to a Roth IRA depends on your modified adjusted gross income (MAGI):
| Filing status | Full contribution | Partial contribution | No contribution |
|---|---|---|---|
| Single or head of household | Under $153,000 | $153,000–$168,000 | $168,000 or more |
| Married filing jointly | Under $242,000 | $242,000–$252,000 | $252,000 or more |
Traditional IRA deduction limits
Anyone with earned income can contribute to a traditional IRA, but the deduction can be limited if you’re covered by a retirement plan at work. For 2026, single filers covered by a workplace plan see the deduction phase out between $81,000 and $91,000 of MAGI. For married couples filing jointly where the contributing spouse is covered, the range is $129,000 to $149,000. If neither you nor your spouse has a workplace plan, the deduction is available at any income.
A traditional IRA contribution you can’t deduct is usually the least attractive option, because you get neither the upfront deduction nor tax-free withdrawals on the earnings.
How the tax math works
Here’s a simplified way to think about it. Suppose you have $7,500 of pre-tax income to put toward retirement and you’re in the 22% bracket.
- Traditional IRA: You contribute the full $7,500 and deduct it, saving $1,650 in federal tax this year. Later, every withdrawal is taxed at your future rate.
- Roth IRA: You pay 22% tax first. If you contribute the full $7,500 to a Roth, it effectively costs you more of your paycheck today, but every dollar of growth is yours to keep.
If $7,500 grows at a hypothetical 7% a year for 35 years, it becomes about $80,000. In a Roth, you keep all $80,000. In a traditional IRA, you’d owe tax on withdrawal: at a 12% rate you’d keep about $70,400, and at a 24% rate about $60,900.
When your tax rate is exactly the same now and later, the two accounts come out roughly even, as long as you invest the tax savings from the traditional deduction. In practice, most people don’t invest those savings, which is one quiet advantage of the Roth.
Who should choose a Roth IRA?
A Roth IRA tends to make sense if you:
- Are early in your career. If you’re in the 10% or 12% bracket now, paying tax at today’s rate is often a bargain compared with what you might pay later.
- Expect your income to rise. Promotions, a career change or a partner’s income could push you into higher brackets.
- Want flexibility. You can withdraw your contributions (not the earnings) at any time without tax or penalty. That makes a Roth a useful backup to your emergency fund, though it works best if you leave it alone.
- Want tax diversification. Having both pre-tax money (like a traditional 401(k)) and tax-free money gives you more control over your tax bill in retirement.
- Want to avoid required minimum distributions. Roth IRAs have none during your lifetime, which makes them useful for estate planning too.
Who should choose a traditional IRA?
A traditional IRA tends to make sense if you:
- Are in a high bracket now, such as 24% or above, and expect a lower rate in retirement.
- Need to lower your taxable income this year, for example to qualify for other tax benefits based on AGI.
- Earn too much for a Roth but can still deduct a traditional contribution (for example, if you have no workplace plan).
- Plan to retire somewhere with lower or no state income tax.
Earning too much for a Roth? The backdoor option
High earners above the Roth limit can sometimes use a “backdoor Roth”: contribute to a nondeductible traditional IRA, then convert it to a Roth. The process is legal, but it has tax traps. In particular, the pro-rata rule means that if you have other pre-tax IRA money, part of the conversion will be taxable. This strategy is worth discussing with a tax professional before trying it.
Withdrawal rules in plain English
Roth IRA:
- Your contributions can come out anytime, for any reason, tax- and penalty-free.
- Earnings are tax-free once you’re 59½ and the account has been open at least five years.
- Taking out earnings early usually triggers income tax and a 10% penalty, though exceptions exist, such as up to $10,000 toward a first home purchase (after five years), disability and certain education costs.
Traditional IRA:
- Withdrawals are taxed as ordinary income.
- Before age 59½, a 10% penalty generally applies on top of the tax, with exceptions similar to those above.
- Required minimum distributions begin in your 70s.
How an IRA fits with your 401(k)
You can contribute to an IRA even if you have a 401(k) at work. A common order of priorities:
- Contribute to your 401(k) up to the full employer match.
- Contribute to a Roth IRA (or traditional IRA if that suits your tax situation).
- Return to your 401(k) and increase contributions toward the $24,500 limit.
IRAs usually offer a wider choice of low-cost funds than workplace plans. Our guide to how a 401(k) works explains the match and the 401(k)’s own Roth and traditional options.
How to open an IRA
- Choose a brokerage. Look for no account fees, $0 trades and low-cost index funds.
- Pick Roth or traditional based on the factors above.
- Link your bank account and contribute. You can make a lump sum or set up monthly contributions, such as $625 a month to reach $7,500.
- Invest the money. This step is easy to miss: cash sitting in an IRA doesn’t grow much. Choose a target-date fund or broad index funds. If you’re new to this, start with our beginner’s guide to investing.
You can make contributions for a given tax year until the tax filing deadline the following April.
Frequently asked questions
Can I have both a Roth IRA and a traditional IRA?
Yes. You can hold both and contribute to each in the same year, as long as your combined contributions stay within the $7,500 limit for 2026 ($8,600 if you’re 50 or older).
What happens if I contribute too much to a Roth IRA?
Excess contributions are charged a 6% excise tax each year they remain in the account. You can avoid this by withdrawing the excess and any earnings on it before your tax filing deadline, or by recharacterizing it as a traditional IRA contribution.
Is a Roth IRA better than a Roth 401(k)?
They work similarly for taxes. A Roth IRA usually offers more investment choices, while a Roth 401(k) has a much higher contribution limit and no income limit. Many people use both.
Can I open a Roth IRA with no job?
You need earned income to contribute. There’s one important exception: a working spouse can fund a spousal IRA for a non-working spouse if they file a joint return.
How much will I have if I max out a Roth IRA every year?
If you contributed $7,500 a year (about $625 a month) for 35 years with a hypothetical 7% average return, you could have roughly $1.1 million, all of it potentially tax-free in retirement. Actual results depend on returns, which vary and aren’t guaranteed.
Making the call
For most young professionals in the 10%, 12% or 22% brackets, a Roth IRA is a strong default: tax-free growth, flexible access to contributions and no required withdrawals. If you’re in a high bracket today and expect a lower one later, a deductible traditional IRA can save more. When you’re unsure, splitting your retirement savings between Roth and pre-tax accounts is a sensible hedge.
Where to start: Check your expected 2026 income against the limits above, then open the account that fits and set up an automatic monthly contribution. Pick an investment the same day. A low-cost index fund is a simple first choice.
