A parent who steps out of the workforce for five years to raise children does not just give up five years of paychecks. Without a plan, those are also five years of zero retirement contributions, zero employer match, and zero compounding on money that never got saved. Over a career, that gap can quietly become the largest single hole in a household’s retirement.
The tax code has a fix that many couples never use because of one misleading rule of thumb: that you need your own earned income to fund an IRA. Married couples filing jointly do not. A spousal IRA lets a working spouse’s income support full contributions to accounts for both spouses, up to $15,000 combined in 2026 for a couple under 50. Here is how the rule works, this year’s numbers, and the fine print on deductions.
The exception built for one-income households
The general rule is that IRA contributions cannot exceed your taxable compensation for the year. The exception, described in the IRS’s IRA contribution limit rules, applies to married couples filing a joint return: a spouse with little or no compensation can contribute based on the other spouse’s earnings. The IRS calls this the Kay Bailey Hutchison Spousal IRA, after the senator who championed it.
Two conditions carry all the weight. You must be married and file jointly, so couples filing separately are out. And the couple’s combined IRA contributions cannot exceed the working spouse’s taxable compensation, which is rarely a constraint when one spouse works full time.
The 2026 numbers
The IRS raised the IRA contribution limit to $7,500 for 2026, up from $7,000, with a catch-up contribution of $1,100 for people 50 and older. So a couple under 50 can put away $15,000 across their two IRAs this year; a couple both 50 or older can save $17,200. Each spouse’s contribution goes into that spouse’s own account, up to that spouse’s own limit; you cannot pour both shares into one IRA.
That ownership detail is a feature, not a technicality. An IRA is individually owned property. For a spouse who spends years out of the workforce, a spousal IRA builds retirement savings, and financial standing, in their own name, regardless of what happens to the marriage or the working spouse’s career.
Traditional or Roth, and the income fine print
A spousal contribution can go into a traditional IRA, a Roth IRA, or a mix, subject to the same income rules as any contribution. For Roth IRAs, eligibility phases out at higher joint incomes under limits the IRS adjusts annually and publishes in Publication 590-A.
For traditional IRAs, the contribution is always allowed, but whether it is deductible depends on workplace-plan coverage, and here the spousal rules are unusually generous. Per the IRS’s deduction limit tables for 2026: if the working spouse is covered by a 401(k) or similar plan at work, that spouse’s own deduction phases out between $129,000 and $149,000 of joint modified adjusted gross income. But the non-covered, non-working spouse’s deduction survives much longer, phasing out between $242,000 and $252,000. In other words, a stay-at-home spouse in a household earning $200,000 can typically deduct the full $7,500 even though the working spouse’s own IRA deduction is gone.
If neither spouse has a workplace plan, both deductions are unlimited by income. And when a deduction is not available, a Roth contribution, or a nondeductible traditional contribution reported on Form 8606, still gets the money growing tax-advantaged.
Timing, and the years it matters most
Contributions for a tax year can be made until the following year’s filing deadline, so a couple can even fund a spousal IRA for the prior year in early spring once they see their full tax picture. But midyear is the cheaper habit: $625 a month into each spouse’s account reaches the 2026 maximum without a lump sum.
The strategy earns its keep during exactly the stretches when saving feels least natural: parental leave, caregiving years for aging parents, a spouse’s layoff or retraining, semi-retirement before Medicare age. In each case the household still has one income and, thanks to this rule, still has two retirement savers. A five-year career break with $7,500 going in annually keeps roughly $37,500 of contributions, plus decades of growth on them, inside the retirement system instead of outside it.
Setting one up takes an afternoon
There is no special account called a spousal IRA; you simply open an ordinary IRA in the non-working spouse’s name at any brokerage or bank and fund it, keeping the joint-filing and compensation rules in mind at tax time. If the working spouse already maxes a 401(k), the spousal IRA is usually the next-best tax-advantaged dollar available to the household.
The couples who lose out are rarely the ones who ran the numbers and chose differently; they are the ones who assumed a paycheck was the price of admission. It is not, and it has not been for decades. If one spouse’s W-2 covers the grocery bill, it can cover two retirements’ worth of IRA contributions too.
