A Married Couple Over 65 Gets Three Deductions Stacked on Top of Each Other in 2026. An IRA Withdrawal That Fits Under All Three Is Taxed at $0, and the Newest One Is Temporary

A traditional IRA withdrawal counts as ordinary income for federal tax purposes. For couples where both spouses are 65 or older, 2026 brings a different calculation. Three separate deductions stack.

A deduction is an amount subtracted from income before tax is figured, and an IRA withdrawal that fits under all three is taxed at $0. A recent piece here covered the new senior deduction for a single retiree. This article covers how the same rules apply to married couples.

Three Deductions That Stack for Couples Over 65

The first layer is the flat amount filers can claim without itemizing. In tax year 2026, married couples filing jointly get $32,200, according to the IRS.

The second layer is the additional standard deduction for age. Each spouse who is 65 or older adds $1,650 in 2026. It’s been part of the tax code for decades and adjusts for inflation each year.

The third layer is the new senior deduction from the One Big Beautiful Bill. It’s $6,000 for each spouse who reaches age 65 by year-end, and married couples must file jointly to claim it.

Joint filers see the phaseout begin once modified adjusted gross income, roughly the total income on the return, exceeds $150,000. For joint filers, the combined $12,000 senior deduction begins phasing out when modified adjusted gross income exceeds $150,000.

The math rests on a few assumptions: the couple files jointly, both spouses are 65 or older by December 31, 2026, they take the standard deduction instead of itemizing, and their income stays under the phaseout. Under those assumptions, the three layers total $47,500.

With no Social Security, pension, or other income, the couple could withdraw that much from their IRAs and owe no federal income tax on it.

How Social Security Shrinks the Tax-Free Amount

Most couples over 65 collect Social Security, and those benefits change the calculation. The IRS uses a measure called provisional income, which is adjusted gross income plus tax-exempt interest plus one-half of Social Security benefits.

Joint filers see some benefits become taxable once that figure passes $32,000, and a larger share kicks in above $44,000. The Social Security Administration says those income thresholds are not indexed to prices or wages.

The couple gets the average benefit for an aged couple where both spouses collect: $3,208 a month after the 2026 cost-of-living adjustment, or $38,496 a year. Each IRA dollar increases provisional income, which draws more of those benefits into taxable income.

Under these assumptions, the IRA withdrawal that fits under the deductions drops to about $30,100. Taxable Social Security uses up the remaining room, about $17,400.

Why These Years Matter for Withdrawals and Roth Conversions

You can use that untaxed space for withdrawals or Roth conversions. A conversion moves money from a traditional IRA into a Roth IRA. The converted amount is taxed as income now, and qualified Roth withdrawals later aren’t included in gross income under the tax code.

These low-bracket years before required withdrawals begin are the cheapest window for conversions, which is the whole subject of a free guide we put together here: The Roth Window.

Pulling money out now also leaves a smaller balance for required minimum distributions, the mandatory annual withdrawals. Current rules set the start age at 73 for people born before 1962, and 75 for later birth years. Each spouse’s start age depends on their own birth year.

Bigger conversions can run into Medicare’s income-related surcharges. In 2026, the Part B premium is $202.90 per person per month for joint income up to $218,000; above that, it rises to $284.10.

Medicare looks back, so 2026 IRMAA would be based on your 2024 tax return. A large conversion this year would show up in 2028 premiums.

What Changes When the Senior Deduction Expires

The senior deduction applies only to tax years beginning before January 1, 2029. It started in 2025, so it covers four tax years.

Once it’s gone, the same couple’s deductions in today’s dollars fall to $35,500. With the same Social Security, the tax-free IRA withdrawal would shrink to about $27,300. The other two layers adjust for inflation each year, so the actual dollar figures after 2028 will differ somewhat.

One Number to Work Out Before the Next Withdrawal

The room left for IRA withdrawals equals total deductions minus the taxable part of Social Security. In 2026, that total is $47,500 for a couple who both qualify. With the average couple’s benefit, about $33,800 of IRA money fits under it.

Pensions, interest, dividends, or bigger Social Security checks all shrink that room. Entering a planned withdrawal into tax software or a draft return before December 31 shows where the line falls for a specific household, and the space is widest while the senior deduction lasts.
