A spouse who has left the paid workforce, whether to raise children, manage a home, or simply because one paycheck covers the household, is not shut out of tax-advantaged retirement saving. The tax code lets a married couple filing jointly fund a full IRA for a non-earning spouse using the working spouse’s income, an option often called a spousal IRA that many households never realize applies to them.
The Compensation Rule That Makes a Non-Earner’s IRA Possible
Ordinarily, an IRA contribution can’t exceed the amount of taxable compensation the account owner personally earned that year. A spouse with no wages, self-employment income, or other compensation would normally be capped at contributing nothing at all. The exception, formally the Kay Bailey Hutchison Spousal IRA provision, lets a married couple filing a joint return count the working spouse’s compensation toward the non-earning spouse’s contribution as well.
The IRS is specific about how the money is measured. Its guidance on IRA contribution limits states that each spouse can contribute up to the standard annual limit to their own IRA, but the combined household total can’t exceed the couple’s combined taxable compensation reported on the joint return. A single working spouse earning enough to cover both contributions can fund two full IRAs; a lower earner may only be able to cover part of the non-working spouse’s contribution.
The non-working spouse must have their own IRA in their own name to receive the contribution; the money can’t simply be added to the working spouse’s existing account. Once opened and funded, the account is owned and controlled entirely by the spouse in whose name it sits, regardless of whose income paid for the contribution.

Whether the Contribution Is Deductible Depends on Which Spouse Has a Work Plan
Funding a spousal IRA is not the same question as deducting it. The IRS’s rules on IRA deduction limits tie deductibility to whether either spouse is covered by a retirement plan at work, not to whose income funded the account. If neither spouse participates in a workplace plan, the full contribution is deductible regardless of household income.
The calculation changes once one spouse has access to a 401(k) or similar plan at their job. A non-working spouse with no workplace plan of their own, married to someone who does have one, gets a considerably more generous income ceiling before the deduction phases out than the working spouse does on their own contribution. Above that higher ceiling, the non-working spouse’s deduction shrinks and eventually disappears, even though they personally have no employer plan at all.
Couples sometimes assume the deduction rules are identical for both spouses simply because the contributions came from the same paycheck. In practice, a household can find the working spouse’s contribution partially non-deductible while the non-working spouse’s contribution to a separate account remains fully deductible, purely because the IRS tests each spouse’s workplace-coverage status separately before applying the income limits.
Those income ceilings move every year. For 2026, the IRS’s retirement-plan cost-of-living adjustments set the non-working spouse’s deduction phase-out, when married to a spouse who does carry a workplace plan, at modified adjusted gross income between $242,000 and $252,000 — nearly double the $129,000-to-$149,000 range that applies to the covered spouse’s own contribution that same year.
Two Accounts Doing the Work of One Income
The practical effect is that a single-earner household is not limited to saving only through the earner’s own IRA or workplace plan. Each spouse maintains an independent contribution limit, including the larger catch-up amount available once a spouse turns 50, and both limits apply in full even though only one spouse is bringing home a paycheck.
That structure matters for households where one spouse stepped away from paid work for years, a pattern still far more common among women than men. Without the spousal IRA provision, a career gap taken to raise children or care for an aging parent would otherwise translate into a permanent gap in that spouse’s own retirement savings, on top of whatever gap it already created in their Social Security earnings record.
Because the account belongs solely to the non-working spouse, it also carries its own beneficiary designations and its own required minimum distribution schedule once that spouse reaches the applicable age, entirely independent of the working spouse’s retirement accounts. A divorce or the working spouse’s death does not automatically affect an account that was never jointly titled to begin with.
A Roth Spousal IRA Runs On a Separate Income Test
The spousal provision isn’t limited to a traditional, pre-tax IRA. The same compensation-sharing rule lets a couple fund a Roth IRA in the non-working spouse’s name instead, using after-tax dollars that grow tax-free and, unlike a traditional IRA, carry no required minimum distributions during the original owner’s lifetime.
Roth eligibility ignores workplace-plan coverage entirely and runs instead on the couple’s combined modified adjusted gross income. The same 2026 IRS figures phase out a married couple’s joint Roth eligibility between $242,000 and $252,000 in combined income, regardless of whether either spouse has a 401(k) at work — a single-earner household with a well-paid earner can lose Roth access for both spouses at once, even though neither one participates in an employer plan.
