Spousal IRA Contribution Limits: Eligibility, Deadlines, and Phase-Outs

For 2026, spousal IRA contribution limits let each spouse put up to $7,500 into their own IRA, or $8,600 if that spouse is 50 or older, even when one spouse earns little or nothing. A couple where both partners are 50-plus can set aside $17,200 combined. Two conditions make it work: the couple files a joint federal return, and the working spouse has at least as much taxable compensation as the two contributions added together.¹

There is no joint IRA. The account belongs to the non-working spouse alone. What makes it “spousal” is only that the eligibility to contribute rides on the other spouse’s earnings.

Who Qualifies

Three conditions all have to be true for the contribution to stand.

The couple is legally married on or before December 31 of the tax year.
The couple files a joint federal income tax return for that year. Filing separately disqualifies the spousal contribution entirely.
The working spouse’s taxable compensation for the year equals or exceeds the total contributed across both IRAs. If you’re putting in $15,000 between the two accounts, the working spouse needs at least $15,000 in qualifying compensation.

The non-working spouse either has no compensation or earns less than the annual IRA limit. Everything above that limit has to be supported by the other spouse’s income.²

The 2026 Limits in Detail

The spousal IRA cap matches the standard individual IRA cap. For 2026, that’s $7,500 per spouse, for a combined $15,000.¹

Anyone who turns 50 or older by December 31 gets a catch-up contribution of $1,100 on top, raising that spouse’s ceiling to $8,600. If both spouses are 50-plus, the household can put away $17,200 for the year.¹ The catch-up was a flat $1,000 for years; under the SECURE 2.0 Act it now adjusts for inflation, which is why it moved to $1,100 for 2026.

The dollar limit is a per-person ceiling across all of that person’s IRAs combined, not per account. If a spouse puts $3,000 into a traditional IRA, only $4,500 more can go into that same spouse’s Roth IRA (assuming they’re under 50). Traditional and Roth contributions share the same annual cap.

Roth Income Limits for Couples

Anyone earning at the higher end of the middle class needs to check the Roth income rules before contributing, because they apply to both spouses’ Roth IRAs based on the joint return’s income.

For 2026, a married couple filing jointly can make full Roth contributions if their modified adjusted gross income is under $242,000. Between $242,000 and $252,000, the allowable amount phases down. At $252,000 or above, direct Roth contributions are off the table for both spouses.³

The non-working spouse’s Roth contribution runs through the same MAGI test, because MAGI comes off the joint return. When income lands inside the phase-out, use the worksheet in IRS Publication 590-A to calculate the reduced amount.⁴

One boundary worth naming: if the couple files separately, the Roth phase-out collapses to $0–$10,000 of MAGI, which knocks out Roth contributions for almost anyone. And separate filing already disqualifies the spousal contribution itself.

When the Traditional IRA Deduction Phases Out

A traditional IRA contribution can be made at any income. Whether it’s deductible is a separate question that turns on workplace plan coverage.

If neither spouse is covered by a workplace retirement plan such as a 401(k), the full contribution is deductible regardless of income. That’s the simplest case.

If the working spouse is covered by a workplace plan but the non-working spouse is not, the deductibility of the non-working spouse’s traditional IRA contribution phases out between $242,000 and $252,000 of MAGI for 2026. Below $242,000, it’s fully deductible. Above $252,000, none of it is deductible.

A non-deductible contribution is still allowed above those thresholds. It just goes in as after-tax money and gets reported on IRS Form 8606, which tracks the after-tax basis so the same dollars aren’t taxed again when they come out.⁵

What Counts as Earned Income

The working spouse’s income has to be “compensation” as the IRS defines it. That covers wages, salary, tips, bonuses, commissions, and net self-employment income. Taxable alimony received under a divorce agreement executed before 2019 also counts.⁴

Investment income doesn’t. Interest, dividends, rental income, pension payments, and Social Security benefits are all excluded. A household living entirely on investments or retirement benefits can’t fund a spousal IRA because there’s no qualifying compensation on either side. Early retirees sometimes miss this: when one spouse leaves work and the other isn’t earning either, the door closes on new IRA contributions.

The Backdoor Roth Route for Higher Earners

Couples above the Roth income limits still have a path in. The backdoor Roth works for a spousal IRA the same way it does for anyone else’s.

The non-working spouse opens a traditional IRA, makes a non-deductible contribution up to the annual limit, then converts that balance to a Roth IRA. Because the contribution went in after-tax, the conversion itself is generally not taxable, apart from any earnings that accumulated between the two steps.

Watch the pro-rata rule. If the non-working spouse already holds pre-tax money in any traditional IRA, the IRS treats the conversion as coming proportionally from both pre-tax and after-tax funds across all of that spouse’s traditional IRAs, which can produce a tax bill you weren’t expecting. The clean version starts from a zero traditional IRA balance and converts quickly.

Both the non-deductible contribution and the conversion get reported on Form 8606 with that year’s tax return. Skipping it is where problems tend to start.⁵

Deadline for 2026 Contributions

Spousal IRA contributions for a tax year are due by the federal filing deadline for that year, not including extensions. For 2026, that means April 15, 2027. Contributions made between January 1 and April 15 of the following year need to be tagged to the correct tax year when they’re deposited.⁶

That gives a couple roughly 15 and a half months to fund a given year, from January 1 through mid-April of the year after. Contributing earlier in the window puts the money to work sooner, and over a 20- or 30-year horizon the difference compounds.

What Happens If You Over-Contribute

Putting in more than the annual limit, or contributing without the eligibility to do so, creates an excess contribution. The IRS charges a 6% excise tax on the excess every year it stays in the account.⁷

Common triggers on the spousal side: overestimating the working spouse’s compensation, forgetting that filing separately kills the contribution, and missing the Roth income phase-out. To avoid the penalty, withdraw the excess and any earnings it produced by the filing deadline, including extensions. For 2026, that’s generally April 15, 2027, or October 15, 2027 with an extension. Missing both dates locks in the 6% charge for that year, and it recurs each year the excess remains.⁴
