A Roth IRA is one of the few accounts where the government lets your investment growth go completely untaxed, in exchange for you paying tax on the money up front instead of later. That trade is powerful, but the account comes with income limits, contribution caps, and withdrawal rules that trip up even experienced savers. This guide covers how Roth IRAs work in 2026, who can use one directly, and the backdoor strategy that lets higher earners get money in anyway.
How much you can contribute in 2026
For 2026, the Roth IRA contribution limit is $7,500 for anyone under 50, and $8,600 for those 50 and older (a $1,100 catch-up contribution). This limit is shared across all your IRAs — traditional and Roth combined — so contributing $7,500 to a Roth IRA means you can't also contribute to a traditional IRA in the same year.
You also need enough earned income (wages, salary, or self-employment income) to cover your contribution; you can't contribute more than you earned in a given year, and investment income alone doesn't count. The deadline to contribute for a given tax year is your tax-filing deadline the following spring, not December 31 — for 2026 contributions, that's generally April 15, 2027 (later if you file an extension for the return itself, though the IRA contribution deadline typically doesn't move with an extension).
Because contributions go in after-tax, a Roth IRA pairs naturally with long time horizons. You can project how contributions compound over decades with the Compound Interest Calculator, or model a Roth IRA alongside other retirement accounts with the Retirement Planning Calculator.
Income limits: who can contribute directly
Unlike a 401(k), a Roth IRA phases out at higher incomes. For 2026, based on modified adjusted gross income (MAGI):
| Filing status | Full contribution | Partial contribution | No contribution |
|---|---|---|---|
| Single | Under $153,000 | $153,000–$167,999 | $168,000 or more |
| Married filing jointly | Under $242,000 | $242,000–$251,999 | $252,000 or more |
If your income falls in the partial range, the amount you can contribute phases down on a sliding scale rather than dropping off a cliff. If you're over the limit entirely, you're not shut out of Roth savings altogether — that's what the backdoor Roth strategy (below) exists for.
Roth vs. traditional: the core tradeoff
The fundamental choice between a Roth and a traditional IRA is when you pay tax:
Traditional IRA: contributions may be tax-deductible today (subject to income and workplace-plan rules), the money grows tax-deferred, and you pay ordinary income tax on withdrawals in retirement.
Roth IRA: contributions are made with after-tax dollars — no deduction now — but qualified withdrawals in retirement, including all the growth, are entirely tax-free.
As a general rule of thumb, Roth contributions tend to make more sense if you expect to be in a higher tax bracket in retirement than you are now — common for younger workers early in their careers. Traditional contributions do more work if you expect a lower tax bracket later, or if you want to reduce this year's taxable income. Because nobody can predict future tax policy with certainty, some savers deliberately hold both types of accounts to hedge the uncertainty.
The two 5-year rules
Roth IRAs have two separate, easily confused five-year rules:
1. The earnings rule. For a withdrawal of earnings to be tax- and penalty-free, you must be 59½ or older, and at least five years must have passed since January 1 of the tax year of your very first Roth IRA contribution (this clock starts once, across all your Roth IRAs, and doesn't restart with each new account).
2. The conversion rule. Each Roth conversion (including backdoor Roth conversions) starts its own separate five-year clock, running from January 1 of the year of that conversion. Withdrawing converted funds before both that five-year period ends and you turn 59½ can trigger a 10% penalty on the converted amount, even though the conversion itself was already taxed.
Your own contributions (not earnings) can always be withdrawn tax-free and penalty-free at any time, at any age — that flexibility is unique to Roth accounts and doesn't exist with a traditional IRA.
Early withdrawal rules and exceptions
Because contributions can come out anytime without penalty, most early-withdrawal questions are really about earnings. Withdrawing earnings before age 59½ and before satisfying the 5-year earnings rule generally triggers both ordinary income tax and a 10% penalty — unless an exception applies, such as:
- A first-time home purchase (up to a $10,000 lifetime limit)
- Qualified higher education expenses
- Unreimbursed medical expenses above a threshold tied to your adjusted gross income
- Birth or adoption expenses, up to $5,000 per child
- Disability of the account owner
- Death of the account owner (for beneficiaries)
These exceptions waive the 10% penalty on earnings; they don't necessarily make the withdrawal completely tax-free unless the account has also independently met the 5-year and age requirements.
The backdoor Roth strategy
If your income is above the direct-contribution limit, the backdoor Roth is a two-step, IRS-sanctioned workaround:
- Contribute to a traditional IRA and treat it as nondeductible (there's no income limit on nondeductible traditional IRA contributions).
- Convert that traditional IRA balance to a Roth IRA. Conversions have no income limit, only direct contributions do.
The catch is the pro-rata rule: if you hold other traditional, SEP, or SIMPLE IRA balances anywhere, the IRS treats all of them as one pool when calculating how much of your conversion is taxable pretax money versus already-taxed basis. If you have significant pretax IRA balances elsewhere, a "clean" backdoor Roth becomes harder to execute without triggering unexpected tax — this is worth reviewing with a tax professional before converting.
Common mistakes to avoid
- Contributing while over the income limit. This creates an excess contribution subject to a 6% excise tax for every year the excess remains in the account.
- Missing the correction deadline. Excess contributions can be withdrawn (along with their earnings) or recharacterized without the 6% tax if fixed by your tax-filing deadline, generally including extensions.
- Leaving contributions uninvested. Money often lands in a default cash or money-market holding inside the account — contributing is only step one; you still need to choose investments.
- Confusing the two 5-year clocks. Treating a conversion's 5-year period as already satisfied because an old Roth IRA passed its own 5-year mark is a common, costly error.
- Ignoring the pro-rata rule on a backdoor Roth. Forgetting about an old rollover IRA can turn an intended tax-free conversion into a partially taxable one.
Frequently asked questions
Can I contribute to a Roth IRA and a 401(k) in the same year?
Yes. The Roth IRA limit is separate from your workplace 401(k) limit, so you can contribute to both, subject to each account's own income and contribution rules.
What happens if I contribute more than the limit?
The excess is subject to a 6% excise tax for each year it stays in the account. You can avoid the tax by withdrawing the excess and any earnings on it, or recharacterizing it, before your tax-filing deadline.
Do Roth IRAs have required minimum distributions (RMDs)?
No. Unlike traditional IRAs, Roth IRAs are not subject to RMDs during the original owner's lifetime, which is part of why they're often used as a later-life or legacy savings vehicle.
Is the backdoor Roth legal?
Yes. The IRS has acknowledged the strategy is permissible as long as each step (a nondeductible contribution, then a conversion) is reported correctly, including tracking basis on Form 8606. The pro-rata rule still applies to the conversion amount.
Should I max out my Roth IRA before my 401(k) match?
Generally no — capturing a full employer 401(k) match first is usually the higher priority, since it's an immediate, guaranteed return that a Roth IRA can't match. After securing the match, many savers turn to maxing a Roth IRA before increasing 401(k) contributions further, largely for the investment flexibility and tax-free withdrawal rules. The Retirement Planning Calculator can help you compare how different contribution orders affect your long-term balance, and the Coast FIRE Calculator can show whether your current savings pace already has compounding on track to carry you the rest of the way.
