Roth IRA Eligibility

You can contribute to a Roth IRA if you have earned income and your modified adjusted gross income (MAGI) is below the IRS phase-out limits. There's no age requirement—Roth IRAs have never had a maximum age limit. The limits vary by filing status, and married-filing-separately filers face the strictest threshold. If your income exceeds the phase-out, a backdoor Roth is still available.

Who Can Contribute to a Roth IRA

The fundamental requirement is straightforward: you must have earned income in the tax year you contribute. Earned income includes W-2 wages, salary, self-employment income, or compensation for services rendered. It does not include passive income such as dividends, capital gains, rental income, or interest.

The amount you contribute cannot exceed the lesser of your earned income or the annual contribution limit ($7,500 for 2026, or $8,600 if age 50+). If you earned $5,000 that year, your maximum contribution is $5,000, regardless of the standard limit.

For minors (including teenagers with summer jobs or side income like babysitting or lawn mowing), the same rules apply. A custodial Roth IRA is required until the age of majority, with a parent or guardian serving as custodian. The minor's earned income determines the contribution limit, not the parent's.

There Is No Age Requirement for Roth Contributions

Unlike traditional IRAs, which now allow contributions past age 70½ (following the SECURE Act's removal of the age limit in 2020), Roth IRAs never had an age limit at all. You can contribute to a Roth at any age, as long as you have earned income.

This matters practically for working retirees. If you're 72 and still employed with earned income, you can contribute to a Roth IRA. There's no requirement to take required minimum distributions (RMDs) from your own Roth during your lifetime. The age restriction only applies to earnings withdrawals (59½+) and the 5-year rule for tax-free treatment—not to the right to contribute.

Understanding Modified Adjusted Gross Income (MAGI) for Roth Eligibility

The IRS doesn't use your standard "adjusted gross income" for Roth eligibility. Instead, it uses a modified version that adds back certain deductions. For Roth IRA eligibility purposes, MAGI is calculated as your AGI before the deduction for IRA contributions themselves.

More specifically, you generally start with your AGI from Form 1040 and add back: (1) any deduction for traditional IRA contributions, (2) student loan interest deduction, (3) tuition and fees deduction, and (4) passive loss deductions. For most people, MAGI is roughly equivalent to your W-2 wages or net self-employment income, before retirement contributions.

The easiest approach: work backward from your 1040. Take your AGI, then add back IRA deductions and the other items above. That's approximately your MAGI for Roth eligibility. For self-employed individuals, MAGI includes 92.35% of net self-employment income after the self-employment tax deduction.

Let the math do itself. The MAGI Estimator walks through every Publication 590-A add-back line-by-line (trad IRA, student loan, §911 foreign income, §135 bonds, §137 adoption), computes your exact phase-out position, and shows how much a $1,000 change to your pre-tax 401(k), HSA, or IRA would move you toward or away from the Roth cliff.

2026 Income Phase-Out Ranges by Filing Status

Your eligibility to contribute begins phasing out at a lower MAGI threshold and completely disappears at an upper threshold. Within the phase-out range, you can make a reduced contribution. Below the lower threshold, you can contribute the full amount. Above the upper threshold, you cannot contribute at all (unless using a backdoor Roth).

How to Calculate a Reduced Contribution Within the Phase-Out Range

If your MAGI falls within the phase-out range, you cannot contribute the full amount. Here's the formula: subtract your MAGI from the upper phase-out limit, then divide by the range width. Multiply that result by the full contribution limit. If the math doesn't work out evenly, round up to the nearest $10.

For example, a single filer with $162,000 MAGI in 2026 falls in the $153,000–$168,000 range. The difference from the ceiling is $6,000 ($168,000 − $162,000). The range width is $15,000. So $6,000 ÷ $15,000 = 40%. The full limit is $7,500, so 40% × $7,500 = $3,000. This filer can contribute $3,000 but not more.

If the calculation yields a positive amount less than $200 (and your MAGI remains below the upper phase-out bound), the statutory floor under §408A(c)(3)(B)(iii) (cross-referencing §219(b)(5)(B)) rounds your allowed contribution UP to $200. Only when your MAGI exceeds the upper phase-out bound is the allowed contribution $0. The IRS applies rounding in your favor (rounded up to the next $10).

The Married-Filing-Separately Trap

If you're married but file separately, the Roth contribution limits become extremely restrictive. The phase-out range is $0–$10,000 MAGI. This means that if you file separately and have any earned income, your eligibility is nearly eliminated unless your MAGI is under $10,000.

Example: A married couple where both spouses earn income could file separately to avoid the higher MFJ phase-out limit, but doing so almost completely blocks Roth contributions. The IRS effectively forces married couples to file jointly if they want Roth access. This is an intentional design meant to discourage married-filing-separately strategies.

If you're separated and filing separately, consult a tax professional. There may be legitimate reasons to file separately, but Roth eligibility becomes collateral damage.

What Disqualifies You From Roth Contributions

No earned income: If you have no W-2 wages, self-employment income, or other earned compensation, you cannot contribute to a Roth IRA directly. A non-working spouse may qualify for a spousal IRA, but a non-working, non-spouse individual has no Roth access.

MAGI exceeds the upper phase-out limit: Single filers earning over $168,000, MFJ over $252,000, and MFS filers earning over $10,000 cannot make direct Roth contributions. However, the backdoor Roth is available.

Filing status MFS above $10,000: Married-filing-separately is economically prohibited from Roth contributions if either spouse earned above $10,000 MAGI.

Non-resident alien status: Non-resident aliens generally cannot contribute to a Roth IRA unless they file a joint return with a U.S. citizen or permanent resident spouse.

Backdoor Roth: The Workaround for High Earners

If your income exceeds the phase-out limits, you cannot contribute directly to a Roth IRA. However, you can still fund one through a "backdoor" strategy: contribute non-deductible dollars to a traditional IRA, then immediately convert those dollars to a Roth. The conversion itself has no income limits.

The catch: if you have pre-tax money in any traditional IRA, SEP-IRA, or SIMPLE IRA accounts, the pro-rata rule applies. The IRS will tax a proportional amount of the conversion based on the ratio of pre-tax to after-tax dollars across all your IRA accounts. This is why a clean backdoor Roth requires no existing traditional IRA balances.

For detailed mechanics, see our Backdoor Roth guide.

Spousal IRA: Exception for Non-Working Spouses

If you're married, file jointly, and one spouse has little or no earned income, the spousal IRA exception allows you to contribute to the non-working spouse's Roth IRA based on the working spouse's earned income. The requirement: the working spouse must have sufficient earned income to cover both spouses' contributions.

Each spouse has their own separate Roth IRA, and each is subject to the standard $7,500 limit (or $8,600 if 50+). The non-working spouse has full control of their own IRA. The phase-out limits apply to the couple's combined MAGI.

Example: Spouse A earns $200,000 as an employee. Spouse B stays home with children and earns $0. The couple can file jointly and contribute $15,000 total (both spouses to their own Roths), assuming their combined MAGI is within the MFJ range ($242,000–$252,000).

For full details, see our Spousal IRA Rules guide.

Custodial Roth IRA for Minors With Earned Income

A minor (anyone under the age of majority in their state, typically 18) can have a custodial Roth IRA if they have earned income. The contribution is limited to the lesser of $7,500 (the 2026 limit) or the minor's earned income for that year.

This is an extraordinarily powerful tool for compound growth. A 16-year-old with summer and part-time jobs earning $7,500/year who contributes consistently from age 16 to 22 will have invested $52,500. At a 7% annual return compounding for 43 years, that grows to roughly $960,000 by age 65. Stretch the contribution window from 16 to 30 (15 years at $7,500 each), and projections easily exceed $2 million by age 65.

A parent or guardian serves as custodian and maintains control of the account until the child reaches the age of majority. After that, the account transfers to the child's name, and they have full control.

See our Custodial Roth IRA Rules guide for complete details.

MAGI Calculation for Roth IRA: Not the Same MAGI as ACA or IRMAA

"Modified Adjusted Gross Income" is a term the tax code uses for many different rules, and each rule's modifications are slightly different. For Roth IRA eligibility under IRC §408A(c)(3)(B)(i), MAGI is your AGI from Form 1040 line 11, with the following specific add-backs: (1) traditional IRA deduction under §219, (2) student loan interest deduction under §221, (3) foreign earned income exclusion under §911, (4) foreign housing exclusion/deduction under §911, (5) tuition and fees deduction (historical, since repealed), and (6) the exclusion for U.S. savings bond interest used for higher education under §135. The add-back for employer-provided adoption benefits under §137 also applies.

Notably not added back: municipal bond interest, qualified dividends taxed at preferential rates, 401(k)/403(b)/457 deferrals, HSA contributions, and pre-tax insurance premiums. This is important for planning: a high-earning W-2 worker can reduce Roth MAGI dollar-for-dollar by maxing their Traditional 401(k) and HSA, potentially moving from "no Roth contribution allowed" to "full $7,500 contribution allowed" without any gross income reduction.

Compare to ACA MAGI under IRC §36B(d)(2): adds back tax-exempt interest, non-taxable Social Security, and foreign earned income. ACA MAGI is generally higher than Roth MAGI. Compare to IRMAA MAGI under the Social Security Act §1839(i): adds back tax-exempt interest to AGI. IRMAA MAGI is typically between Roth and ACA MAGI. A taxpayer can have three different MAGI figures simultaneously for three different tax features, and using "MAGI" colloquially is a reliable way to get the wrong answer. Always specify which MAGI you mean.

Your Filing Status Is Determined on December 31

IRC §7703(a) fixes your filing status as of the last day of the tax year. If you marry on December 30, you file jointly (or MFS) for the entire year; if you divorce on December 31, you file single (or head of household) for the entire year. This creates a year-end planning lever:

Divorce timing and Roth eligibility: A couple with $300,000 combined income is fully phased out of Roth contributions filing MFJ ($300,000 > $252,000). If they divorce on December 30 and each has $150,000 of income, both file single and each sits just below the $153,000 floor—unlocking full Roth contribution capacity for both. Divorce attorneys rarely raise this, but year-end timing can be worth thousands in cumulative Roth tax benefit for high-income couples genuinely heading toward separation.

Marriage timing and the "marriage penalty" for unequal earners: If one partner earns $200,000 (single, no Roth eligibility under 2026 rules) and the other earns $50,000 (single, full Roth eligibility), marrying on December 31 makes their combined $250,000 MAGI deep inside the MFJ phase-out ($242,000–$252,000), sharply reducing the lower earner's Roth eligibility for that year. A January wedding preserves the filing-status separation for the prior tax year. This is a vanishingly minor consideration, but for engaged couples already choosing a wedding window, a $7,500 Roth contribution difference may factor in.

Nonresident Aliens and Dual-Status Returns

A nonresident alien generally cannot contribute to a Roth IRA because the contribution requires "taxable compensation" (Form W-2 or Schedule C income reported on Form 1040). Nonresident aliens file Form 1040-NR and report income under different rules. However, there are two nuanced exceptions:

Joint return election (IRC §6013(g)): A U.S. citizen or resident married to a nonresident alien can elect to treat the NRA spouse as a U.S. resident for the entire tax year, filing Form 1040 MFJ. This opens Roth contribution eligibility for the NRA spouse based on their combined income. The election is irrevocable until affirmatively terminated, and it subjects the NRA spouse's worldwide income to U.S. tax—often a major drawback. Worth modeling but rarely the right choice.

Dual-status year: If you become a U.S. resident or cease to be one mid-year, you file a dual-status return. During the resident portion of the year, you may be eligible to make a Roth contribution based on resident-period earned income, but the contribution mechanics are tricky. Tax-treaty provisions with certain countries (Canada, UK) may affect the analysis. Expats and incoming immigrants with retirement planning needs should consult a cross-border tax professional.

Tax Extensions and the Contribution Deadline

A common misconception is that filing a Form 4868 extension extends the Roth IRA contribution deadline. It does not. IRC §219(f)(3) ties the contribution deadline to the "due date" of the return, which is fixed at April 15 (or the next business day if April 15 falls on a weekend or holiday). Tax extensions extend the return-filing deadline to October 15 but do not extend the contribution deadline. You cannot contribute to a Roth IRA for 2025 on May 1, 2026, even if you're on extension.

The narrow exception: if you are in a federally declared disaster area, IRS disaster relief may extend the contribution deadline along with other tax deadlines. The IRS posts these extensions at irs.gov/newsroom. Combat zone service members also have the 180-day post-deployment extension that does apply to IRA contributions.

For late discoveries of eligibility (e.g., you realized in October 2026 that you could have contributed for 2025), you are simply out of luck for that year. Plan contributions as early in the year as cash flow permits, and use the prior-year designation only as a last resort by April 15.

Documentation & Verification for Eligibility

Your IRA custodian (typically your broker or bank) doesn't verify your income at contribution time. However, you are responsible for ensuring you meet the requirements. If you make a contribution and later the IRS discovers you exceeded the phase-out limits, you'll owe excise taxes and interest on the excess contribution.

Keep records of your income calculation, MAGI, and earned income documentation. For self-employed individuals, keep copies of Schedule C and your 1040. For employees, keep your W-2s. If questioned, you'll need to demonstrate that your contribution was eligible based on your income that year.
