A Roth IRA is a retirement account with one standout feature: you pay tax on the money going in, and then never pay tax on it again - not on the growth, not on the withdrawals in retirement. For a lot of savers, especially younger ones, that’s the best deal in personal finance.
The trade is simple. A Roth IRA (individual retirement account) gives you no tax break today. In exchange, decades of investment growth come out completely tax-free once you’re retired. You’re choosing to pay tax now, at today’s rate, to skip it later.
Here’s exactly how a Roth IRA works, the 2026 limits and income cutoffs, and the rules worth knowing before you open one.
The core idea: pay tax now, skip it later
Every retirement account gets a tax break somewhere. The question is only when. A Roth IRA puts the break at the back end.
You contribute money that has already been taxed - it comes from your take-home pay, no deduction. That money is invested and grows for years or decades. Then, in retirement, qualified withdrawals of both your contributions and all the growth come out tax-free. If you put in $7,000 and it grows to $70,000, you withdraw the full $70,000 without owing a cent of federal income tax on it.
Compare that to a traditional account, where you get the tax break upfront but pay ordinary income tax on every dollar you withdraw later. Same account family, opposite timing - our traditional vs Roth guide covers the full comparison.
The 2026 contribution limits
The IRS sets IRA limits each year. For 2026, from IRS Notice 2025-67:
| Limit | 2026 amount |
|---|---|
| Roth IRA contribution | $7,500 |
| Catch-up if you’re 50 or older | $1,100 extra |
A few things to know about that limit:
- It’s the combined limit across all your IRAs. If you have both a Roth and a traditional IRA, $7,500 is the total you can split between them - not each.
- You need earned income (wages or self-employment income) at least equal to your contribution. No job income, no Roth IRA contribution - with one exception, a spousal IRA, that lets a working spouse contribute for a non-working one.
- A Roth IRA is separate from a workplace 401(k), so you can fund both in the same year. See 401(k) vs IRA for how they fit together.
The income limits (the Roth’s one big catch)
Unlike a 401(k), a Roth IRA has an income ceiling. Earn too much and your allowed contribution shrinks, then disappears. For 2026 (from IRS Notice 2025-67), the phase-out ranges based on your modified adjusted gross income (MAGI - roughly your income after certain adjustments) are:
| Filing status | Full contribution below | No contribution at or above |
|---|---|---|
| Single or head of household | $153,000 | $168,000 |
| Married filing jointly | $242,000 | $252,000 |
| Married filing separately | $0 | $10,000 |
Between the two numbers, you can contribute a reduced amount. Above the top number, you can’t contribute to a Roth IRA directly at all.
If you earn above the cutoff, you’re not entirely shut out - many high earners use a “backdoor Roth” (contributing to a traditional IRA and converting it to Roth), which is legal but has tax wrinkles worth researching against the current IRS rules before you try it.
The rules that make it flexible
Two features make the Roth IRA unusually friendly compared to other retirement accounts.
Your contributions come out anytime, tax- and penalty-free. Because you already paid tax on the money you put in, you can withdraw your contributions (not the earnings) at any age without tax or penalty. That makes a Roth IRA double as a deep backup fund. It’s still best left to grow - but the access is real. (Keep a separate emergency fund first, so you rarely have to touch it.)
No required withdrawals during your lifetime. Traditional retirement accounts force you to start taking money out at a certain age (required minimum distributions). A Roth IRA has no such requirement for the original owner - you can let it grow untouched as long as you like, which makes it a strong tool for passing money to heirs.
The 5-year rule and the age test
For earnings (the growth, not your contributions) to come out completely tax-free, a withdrawal generally has to be “qualified,” which means two conditions:
- You’re at least 59 and a half years old (or the withdrawal is for a specific allowed reason, like a first home up to a limit, disability, or death).
- The five-year rule: at least five tax years have passed since you first opened and funded a Roth IRA.
Take earnings out before meeting both, and that portion can owe income tax plus a 10% penalty. Your contributions, again, are always fair game to withdraw - the 5-year rule only gates the earnings. The practical takeaway: open a Roth IRA sooner rather than later, even with a small amount, just to start the five-year clock.
A worked example: why it fits young savers
The Roth IRA shines brightest when you have decades of growth ahead and a relatively low tax rate today. Here’s the shape of it (illustrative numbers):
Say you’re 30 and contribute $6,000 a year to a Roth IRA. At an illustrative 7% average annual return, after 30 years - at age 60 - that grows to about $567,000. Of that, only $180,000 is money you contributed; the other $387,000 is pure growth.
In a Roth IRA, you owe $0 in federal income tax on that $387,000 of growth when you withdraw it in retirement. In a traditional account, that same growth would be taxed as ordinary income on the way out. You paid tax on the $180,000 once, upfront, at your working-years rate - and the entire $387,000 gain escaped tax. Returns aren’t guaranteed and real markets swing, but the tax structure is the point: growth you never pay tax on. Run your own numbers in the compound interest calculator and see the full picture in the retirement calculator.
Is a Roth IRA right for you?
A Roth IRA tends to fit when:
- You’re early in your career and expect to earn more (and possibly pay a higher tax rate) later. Paying tax now at a lower rate is the winning move.
- You want tax-free income in retirement and flexibility - no forced withdrawals, and easy access to your contributions if life demands it.
- You’re under the income limits above, so you can contribute directly.
It’s less obviously the pick if you’re a high earner in your peak years expecting a lower tax rate in retirement - a traditional deduction now might be worth more. When genuinely unsure, splitting between Roth and traditional is a reasonable hedge. Just don’t let the decision stall you: contributing consistently matters far more than nailing the tax flavor.
Common mistakes to avoid
Contributing, then earning your way past the income limit. This one catches people every year. You put in your $7,500 in January, confident you’re under the cap - then a raise, a bonus, or a strong self-employment year pushes your MAGI over the ceiling ($168,000 single, $252,000 married filing jointly for 2026). Now some or all of that contribution is an “excess contribution.” The IRS charges a 6% excise tax on the excess for every year it stays in the account. A full $7,500 disallowed contribution costs you $450 a year, again and again, until you fix it. The fix is simple if you act in time: withdraw the excess plus any earnings it made before your tax-filing deadline (including extensions), or “recharacterize” it - tell the brokerage to move it into a traditional IRA instead. Catch it before the deadline and you owe no 6% penalty.
Treating each IRA as its own $7,500 bucket. The $7,500 limit is combined across every IRA you own. Two IRAs funded at $7,500 each is not $15,000 of room - it’s $7,500 of contributions and $7,500 of excess, with that same 6% tax attached to the extra.
Confusing your contributions with your earnings. The “take your contributions out anytime” rule is real, but it stops at the money you actually put in. Your earnings (the growth) are not free to touch: pull them before age 59 and a half and before the five-year mark, and they can owe income tax plus a 10% penalty. Keep a rough tally of your contribution basis (the running total you’ve put in) so you always know how much is genuinely penalty-free to withdraw versus how much is earnings you should leave alone.
FAQ
Can I withdraw from a Roth IRA before retirement?
Your contributions - the money you put in - can be withdrawn at any time, tax- and penalty-free, because you already paid tax on them. The earnings (growth) are different: pull those before age 59 and a half and before the five-year mark, and they can owe income tax plus a 10% penalty. It’s best left to grow, but the access to contributions is genuine.
What if I earn too much for a Roth IRA?
For 2026, direct Roth IRA contributions phase out between $153,000 and $168,000 of income for single filers, and $242,000 to $252,000 for married couples filing jointly. Above the top of your range you can’t contribute directly, but a “backdoor Roth” is a legal route many high earners use - research the current IRS rules or ask a tax professional before trying it.
Roth IRA or Roth 401(k) - what’s the difference?
Both give tax-free retirement growth. A Roth 401(k) comes through your employer with a much higher limit ($24,500 for 2026) and possible matching, but a fixed fund menu. A Roth IRA you open yourself with a $7,500 limit but far more investment choice - and it has income limits a Roth 401(k) doesn’t. Many people use both; see 401(k) vs IRA.
How much should I put in a Roth IRA?
As much as you can up to the $7,500 limit (2026), but usually after you’ve captured your full employer 401(k) match first, since that match is free money. Even small, consistent contributions compound powerfully over decades - and opening one early starts the five-year clock.
