A 65-Year-Old Couple With $380,000 Can Convert $47,500 This Year at $0 Federal Tax. The Average Couple Converts $0 and Pays Tax on Every Dollar at 73
Most couples near retirement sit on a growing tax bill without realizing the window to shrink it quietly closes in 2028. The math behind one overlooked strategy reveals just how wide that gap can get.

This article walks through how a Roth conversion works for a married couple in 2026, starting at age 65. It uses a hypothetical $380,000 traditional IRA and IRS figures for the current tax year. The core question: how much pre-tax money can move into a Roth account before any federal income tax applies, and what happens to households that leave the balance untouched until required withdrawals begin?
Where a $380,000 Balance Sits Among Couples Near Retirement
The Federal Reserve’s 2025 Survey of Consumer Finances, released in October 2026, puts the average retirement account balance for households aged 65 to 74 at $768,000. The median for that group is $257,000, meaning half of all households in this age range with a retirement account have saved less than that. A $380,000 balance falls above the median but well below the average, a gap that reflects how sharply concentrated high balances are at the top of the distribution.
How $47,500 Can Be Converted With No Federal Tax in 2026
A Roth conversion counts as ordinary income in the year it occurs. For tax year 2026, the standard deduction for married couples filing jointly is $32,200, and each spouse aged 65 or older adds $1,650 to that base. The One Big Beautiful Bill Act, signed in July 2025, created a senior deduction of $6,000 per person aged 65 or older, covering tax years 2025 through 2028. It phases out for joint filers with modified adjusted gross income above $150,000, a threshold this couple stays well beneath.
Stack those three pieces together: $32,200 base deduction, plus $3,300 from two age-65 add-ons, plus $12,000 from two senior deductions, and the total shield reaches $47,500. A conversion of exactly that amount leaves $0 of taxable income and $0 in federal tax, provided the couple has no other taxable income during the year. That profile fits a retired household living on cash savings or taxable brokerage accounts while delaying Social Security.
Once those deductions are used up, additional income faces the standard rate structure. For joint filers in 2026, the 10% bracket covers the first $24,800 of taxable income and the 12% bracket applies to income above that. At those rates, $47,500 of taxable income would generate a federal tax bill of $5,204, so the value of the full deduction stack is real and measurable.
Leaving the Balance Alone Ends in Required Withdrawals
The alternative path is leaving the entire balance in the traditional IRA until required withdrawals kick in. Under SECURE 2.0, account owners born between 1951 and 1959 must start required minimum distributions (RMDs) at age 73. A couple turning 65 in 2026 was born in 1961, so they fall under the later rule: people born in 1960 or later start RMDs at age 75.
At age 75, the IRS Uniform Lifetime Table sets the distribution period at 24.6 years. For a $380,000 balance, that translates to a first-year RMD of about $15,447. The full withdrawal is taxable at ordinary income rates. By that point, Social Security has typically started, and the taxable portion of those benefits consumes part of the deductions that were available at 65, leaving less room to absorb additional income without tax.
The stakes of getting RMDs wrong are significant. Missing a required withdrawal triggers a 25% excise tax on the amount that should have been taken. Older Vanguard research found that 20% of account holders subject to RMDs deposit the money directly into taxable accounts even though they had no choice but to withdraw it, effectively converting a tax-deferred asset into a taxable one without any planning benefit.
A Three-Year Window Before the Senior Deduction Expires
The full $47,500 deduction package depends on the senior deduction, which expires after 2028. After one conversion of that size, the IRA balance drops to $332,500 before any investment growth. Converting the same amount in 2027 and 2028 would leave roughly $237,500 in the traditional IRA by age 68, assuming no market growth or loss.
Roth IRAs carry no RMDs for the original owner, and qualified withdrawals come out entirely tax-free. The years between the last paycheck and the first required withdrawal represent the lowest-cost window to act. Our free guide covers the Roth window.
Several other factors shape the analysis. State income tax applies separately and varies widely. Conversions raise modified adjusted gross income, which can push Medicare Part B and Part D premiums higher through IRMAA surcharges and can increase the taxable share of Social Security benefits. The couple also needs liquid assets outside the IRA to cover living expenses during conversion years, since using IRA funds to pay the tax bill defeats the purpose.
How the Two Paths Compare
At 65, this couple holds $47,500 of annual deductions that go entirely unused if taxable income stays near zero. Unused deductions do not carry forward to future years. Converting nothing preserves the full pre-tax balance, but required withdrawals will begin at 75, taxed at ordinary rates on top of whatever Social Security income is already in the picture. The largest conversion opportunities open before Social Security begins, run through the end of 2028 while the senior deduction is in force, and represent the lowest after-tax cost available to a household at this savings level.
Editor’s note: This update replaces the 2022 Federal Reserve Survey of Consumer Finances retirement savings figures with data from the 2025 survey, released in October 2026, raising the median balance for households aged 65 to 74 from $200,000 to $257,000 and the average from $609,230 to $768,000. The RMD calculation for the hypothetical 1961-born couple was also corrected from the age-73 divisor of 26.5 to the applicable age-75 divisor of 24.6, changing the estimated first-year required withdrawal from $14,340 to approximately $15,447.
