Spousal IRA Contribution Calculator 2026

Two IRAs, one compensation budget

Filing a joint return does not create a joint IRA. Enter each spouse’s age at the end of 2026, IRA-qualified compensation and all 2026 Traditional plus Roth IRA contributions already made. Retirement-account rollovers do not consume this annual contribution limit. Use compensation after applicable adjustments, not gross business receipts or investment income.

Why both remaining amounts are conditional

The higher-compensation spouse is limited by their own compensation. For the lower-compensation spouse, joint compensation is reduced by the other spouse’s IRA contributions. When earnings are equal, each uses their own compensation. This is a coordination tool: do not fund both displayed maxima at once if their sum exceeds the joint compensation left. Enter one proposed contribution in already-paid to test the other person’s remaining room.

A single earner with $12,000 compensation

At age 40, a spouse with $12,000 compensation who has contributed $7,500 leaves $4,500 of compensation for a nonworking spouse. With $5,000 and $2,000 of compensation, the higher earner can contribute no more than $5,000. After that is entered as paid, the lower earner has $2,000 left. The tool does not tell the couple to contribute $5,000 plus $7,000 simultaneously.

Age at year end	Personal dollar ceiling
Under 50	$7,500
50 or older	$8,600

Contribution capacity is not a deduction

Use this tool only for married filing jointly Traditional IRA capacity. Workplace-plan coverage and modified AGI may reduce a deduction without reducing the contribution capacity shown here. Roth IRA MAGI eligibility is a separate test. Special section 501(c)(18) adjustments are not modeled; confirm adjusted compensation before entering it. Paid-above-capacity results identify a review item, not a computed excess-tax bill.

Prepare the household record before testing a contribution

Start with the tax year and filing status, not with the amount you want to deposit. Then distinguish each spouse’s own eligible compensation from the household total. An IRA remains an individual account even when joint compensation supports a contribution for a spouse with little or no earnings. The calculator is a way to audit the compensation constraint; it does not turn two spouses’ accounts into a joint IRA or give permission to contribute to an account you do not own.

Collect the contributions already made for each spouse across traditional and Roth IRAs for the selected year. Do not enter a rollover as a new annual contribution. Do not omit another IRA merely because it is held by a different provider. The useful question is how much annual contribution capacity remains under the inputs, rather than how much money the household can move between existing retirement accounts. Use rounded example numbers if you are only comparing scenarios; personal identifiers are not needed.

Read conditional room without double-counting it

A result for one spouse can depend on what the other spouse contributes. For example, a household with $8,000 of eligible compensation cannot support two $7,000 contributions simply because each spouse has a $7,000 individual ceiling. If one spouse has already used $5,000, only $3,000 of the household compensation remains available for the other, before considering any smaller individual remaining limit. This is an arithmetic example, not a statement of the indexed limit for your selected year.

The displayed conditional room assumes the other spouse’s entered amount stays as entered. It is not a pair of independent approvals that can both be maximized at once. Change one spouse’s contribution and inspect the other spouse’s result again. A negative or inconsistent starting record is a reason to reconcile contributions with the custodians, not a reason to hide the record by reducing the compensation input until a green result appears.

Contribution capacity is not deductibility or Roth eligibility

The same dollar can fit within an annual compensation constraint without qualifying for a traditional IRA deduction or a direct Roth IRA contribution. Workplace plan coverage and modified adjusted gross income can affect those separate tests. This tool does not calculate a complete tax return, the traditional deduction phaseout, the Roth income phaseout, an excess-contribution excise tax or a corrected distribution. Its result should therefore be read as a limited capacity check, not “the IRS will allow every tax benefit shown by an IRA provider.”

An age-based higher limit belongs to the particular spouse who qualifies, not automatically to both people. Keep the spouses separate when checking that branch and do not transfer unused age-based room from one account owner to the other. The source section states the indexed year used for the tool. A provider’s interface may show a different year or include deposits allocated to a different year, so reconcile that difference before treating it as a calculator error.

Use the result as a short reconciliation checklist

Compare the selected year, account owner, prior contributions, eligible compensation and household remaining amount with the records you will actually use. If the figures do not reconcile, pause the contribution and ask the custodian or a qualified tax professional to identify the mismatch. Save the assumptions rather than just a final balance: the capacity can change if compensation or another contribution changes. For an error report to this site, send a fictionalized household example and the official rule you believe was missed, rather than a tax return or account statement.

Frequently Asked Questions

Can a nonworking spouse contribute?

With a joint return and sufficient eligible combined compensation, yes, in a separate IRA. The other spouse’s IRA contributions reduce the compensation available.

May I add the two room numbers?

Only if the combined contribution also fits the joint compensation left. Each number holds the other person’s currently entered paid amount fixed.

Does the result approve a Roth contribution or deduction?

No. It does not test Roth MAGI or Traditional IRA deduction phaseouts.
