How Much a Married Couple Over 65 Can Withdraw From an IRA in 2027 and Still Pay No Federal Tax

Retired couples can withdraw a surprisingly large amount from an IRA without owing the IRS anything, but one Social Security choice quickly lowers that figure. Beyond a certain point, every additional dollar is taxed almost twice.

A married couple where both spouses are older than 65 can take a sizable IRA distribution in the coming year and still owe no federal income tax. The exact amount depends mainly on one question: have they started claiming Social Security?

If they have not filed for benefits, the zero-tax threshold is roughly $47,500 based on 2026 figures. If they receive the average couple’s benefit, that limit falls to about $33,800 because IRA withdrawals push part of their Social Security into taxable income.

Three Deductions Create a $47,500 Tax-Free Window

For a married couple filing jointly, age 65 and older, three deductions combine:

• Standard deduction: $32,200 for married couples filing jointly in tax year 2026.
• Additional age-65 deduction: $1,650 per spouse for 2026.
• Senior deduction: $6,000 for each spouse 65 or older under 26 U.S.C. § 151(d)(5)(C), created by the One Big Beautiful Bill. It applies to tax years beginning before January 1, 2029. It phases out by 6% of modified adjusted gross income above $150,000 on a joint return, a level these examples do not reach.

Added together, those deductions equal $47,500. A couple with no other income could withdraw that amount from a traditional IRA and still have $0 of taxable income. The $6,000 deduction is fixed by law. The standard deduction and age-65 add-on rise with inflation, so the 2027 limit should be slightly higher.

Social Security Reduces the Tax-Free IRA Amount to About $33,800

Most couples over 65 already receive Social Security, and that changes the calculation. The IRS uses “provisional income,” which includes other income plus half of Social Security. For joint filers, benefits begin becoming taxable above $32,000, and a second threshold appears above $44,000. Those limits are written into law and do not adjust for inflation. At the highest level, as much as 85% of benefits can become taxable.

Consider a couple receiving the average benefit for an aged couple, $3,208 a month after the 3.6% COLA for 2027. That totals $38,496 a year.

That couple receives more than $72,000 in cash and still owes no federal income tax. The IRA withdrawal is lower than it would be if no Social Security benefits were being paid.

Why Every Dollar Above the Limit Counts Nearly Twice

This is the Social Security tax torpedo. In this income range, each extra IRA dollar also makes 85 cents of benefits taxable, so taxable income increases by $1.85.

Tax brackets still apply from the bottom up, so only income above the line is taxed at the starting rate of 10%. But because each dollar also pulls in additional taxable benefits, the effective marginal rate comes to 18.5%. An extra $1,000 of withdrawals can cost about $185. Once income reaches the 12% bracket, the effective rate rises to 22.2%.

The senior deduction does not change that calculation. It is applied after adjusted gross income is determined, so it does not reduce the income used in the Social Security taxation formula.

Medicare Is Unaffected by a $0 Federal Tax Bill

Medicare’s income-related monthly adjustment amount, or IRMAA, is based on modified adjusted gross income from two years earlier. A 2027 withdrawal affects 2029 premiums. For 2026, the first joint surcharge tier begins above $218,000, lifting Part B premiums from $202.90 to $284.10 a month per person. Both of the example households remain well below that level. A large Roth conversion on top of the withdrawal could still push income over the threshold.

Three Ways to Expand the Zero-Tax Limit

1. Withdraw before claiming Social Security. In the years before benefits begin, the full deduction stack can shield IRA money without any federal tax. Delaying claims can also increase future monthly benefits.
2. Use the remaining window in 2027 and 2028. Under current law, the $6,000 senior deduction ends after 2028. Roth conversions count as income just like withdrawals, so converting up to the zero-tax line while that deduction is still available can move money out of the IRA without federal tax.
3. Make charitable gifts directly from the IRA. Qualified charitable distributions go straight to a charity and are excluded from adjusted gross income. That helps keep provisional income lower and counts toward required minimum distributions, which generally begin at age 73.

State tax rules are different. Some states tax IRA withdrawals fully, while others exempt part or all of retirement income, so no federal tax does not necessarily mean no state tax. Because the tax penalty, IRMAA, and the 2028 sunset all interact, it is wise to model the numbers with a CPA or fiduciary advisor before setting a withdrawal amount.
