A stay-at-home parent fills out an online application to open a Roth IRA at a major brokerage. The form asks for her annual earned income. She enters $0. The system flashes a red error: “You must have earned income to contribute to a Roth IRA.” She closes the browser, assuming she can’t have one. Months later, her financial advisor mentions she should have been funding a Roth IRA every year through her husband’s earnings. The IRS rule has allowed this for decades. The brokerage's online form has not caught up.
A non-working spouse can open and contribute to a Roth IRA when the couple files jointly. The mechanism is the spousal IRA rule, although the IRS never calls the account a “spousal IRA.” It’s a regular Roth IRA, opened in the non-working spouse’s name, owned entirely by that spouse.
The annual contribution limit applies to each spouse independently. Combined IRA contributions for both spouses cannot exceed the taxable compensation reported on the joint return, but otherwise each spouse can contribute up to the standard annual limit plus the age-50 catch-up if eligible. A household with $200,000 of W-2 wages and one stay-at-home spouse can fund two full Roth IRAs to the annual limit.
“Non-working” covers more situations than the term suggests. Stay-at-home parents, retirees, students, spouses between jobs, and business owners who took no salary that year all qualify. The test is whether the spouse’s own earned income falls short of the contribution limit, with the working spouse’s earnings making up the difference on the joint return.
The spousal IRA rule requires earned income on the joint return. Wages and self-employment income count. Investment income, pension distributions, Social Security, and rental income do not. A retired couple living entirely on dividends and Social Security cannot contribute to a Roth IRA, regardless of total wealth.
Filing jointly is required. Married filing separately disqualifies the spousal IRA mechanism entirely. There is no married-filing-separately workaround.
Joint MAGI phase-outs apply to direct Roth contributions for both spouses. If the couple’s combined income exceeds the upper bound of the Roth phase-out range, neither spouse can contribute directly. The backdoor Roth path is available to either spouse independently above the phase-out.
The contribution deadline is the tax filing deadline of the following year, generally April 15, with no extension available beyond that date. Missing the deadline means the contribution can’t be made for that year. The window closes on April 15 and stays closed.
The account belongs to the non-working spouse permanently. The working spouse can fund the contribution, but the legal owner of the account is the spouse whose name is on it. In a divorce, the IRA remains an individual account, though the marital-property treatment depends on state law and the divorce decree.
A wife retired at 58. Her husband, 60, still works full-time as a senior engineer making $180,000. Their joint MAGI sits comfortably under the Roth phase-out for joint filers. She has a 401(k) from her old employer that she rolled to a Traditional IRA, plus several years before Social Security.
In March of the following year, before the contribution deadline, the husband contributes the full annual limit to his own Roth IRA. His wife opens a Roth IRA in her name at the same brokerage and contributes the full annual limit plus the age-50 catch-up. Both contributions go in clean. Her Roth IRA is fully owned by her, in her name, even though every dollar in it came from his earned income.
Run the same couple ten years later. Both fully retired. Income comes from Social Security, pension distributions, and investment dividends. Total household income is $300,000 a year. They want to keep contributing to Roth IRAs. They can’t. Neither spouse has earned income. The spousal IRA rule requires wages or self-employment income, and they have neither.
A different couple, late 30s, files jointly. The husband works full-time. The wife took an unpaid sabbatical to write a novel. She earned $0 that year. Joint MAGI is $145,000. He contributes the annual limit to his own Roth IRA. She opens a Roth IRA in her name and contributes the same amount based on his earnings. The novel may or may not sell. Her Roth IRA grows tax-free regardless.
A non-working spouse can open and own a Roth IRA whenever the couple files jointly and at least one spouse has earned income that supports the contribution. The account is in her name. The growth is hers. The eventual tax-free distributions in retirement are hers.
The custodian’s online form may not handle the situation gracefully. A phone call to customer service usually resolves it. The IRS doesn’t require a special account type. The brokerage just needs to open a standard Roth IRA in the non-working spouse’s name.
Filing jointly opens the door. Earned income supports the contribution. The annual deadline closes the window for that year. After that, the rest is just paperwork.
