What $5,800 a Month Really Looks Like in Retirement at 66 When Half Your Income Is Pension and Half Is RMD

A retired teacher and her husband, both older than 65, are reviewing their retirement income and asking whether they are making the most of their resources. Her state pension provides $2,900 per month, while voluntary withdrawals from their combined 401(k) and IRA balances generate another $2,900. Together, the household brings in $5,800 per month, or $69,600 annually. Neither spouse has claimed Social Security benefits, choosing instead to delay until age 70. Their central question is whether current income is sufficient and whether they are missing valuable planning opportunities during the four-year window before Social Security begins.

This type of situation is more common than many retirees realize. Suze Orman addressed a similar question on her podcast from a listener in her mid-60s who had a teacher pension and IRA assets and wanted to understand how Roth conversions could affect Medicare costs. As Orman explained, money converted from a traditional retirement account into a Roth counts as ordinary income in the year of conversion. That interaction among retirement account withdrawals, taxes, Medicare premiums, and future Social Security benefits sits at the heart of every planning decision this couple now faces.

The Snapshot

• Ages: 66 (retired teacher) and 65+ (spouse), married filing jointly
• Gross income: $69,600 a year, split evenly between a state teacher pension and voluntary retirement-account withdrawals
• Location: A no-state-income-tax retirement community
• Social Security status: Deferred, with claiming planned at 70
• Core issue: A four-year, low-bracket window to reshape future tax exposure before Social Security and larger RMDs stack on top

Why the Tax Picture Is Better Than It Looks

Both income streams are taxed as ordinary income. The pension is fully taxable, and withdrawals from pre-tax retirement accounts are too. That sounds like a heavy burden until the standard deduction steps in. For 2026, the married-filing-jointly standard deduction is $32,200, and both spouses qualify for an additional $1,650 each for being at least 65. On top of that, they may also qualify for the separate $6,000 senior deduction per person, a temporary provision available from 2025 through 2028 under the One Big Beautiful Bill Act. Because both spouses are at least 65, the combined senior deduction for this household can reach $12,000, though it begins to phase out when modified adjusted gross income exceeds $150,000 and disappears entirely at $250,000. Stack all those deductions together and taxable income could land near $22,100.

That figure sits entirely inside the 10% federal bracket, which runs to $24,800 of taxable income for joint filers in 2026. The 12% bracket extends all the way to $100,800. If the couple qualifies for the full senior deduction, their federal bill would be closer to $2,200 rather than $4,000, and take-home income would run roughly $5,617 per month before Medicare premiums or other deductions.

The real prize here is the open space inside the 12% bracket. Even after the senior deduction pulls taxable income down toward $22,100, tens of thousands of dollars of room remain before the 22% bracket begins. That headroom is a valuable runway for Roth conversions at today’s lower rates, and it closes permanently once Social Security turns on.

That runway is the single most important number on the page. Once Social Security turns on at 70 and RMD percentages climb with age, ordinary income will rise, and so will the marginal rate applied to every extra dollar converted or withdrawn. Acting now, while the brackets are favorable, is the strategic priority.

A Hidden Trap Inside the Senior Deduction

There is one wrinkle in the senior deduction that every retiree doing Roth conversions needs to understand. Traditional IRA distributions and Roth conversions both count as ordinary income and flow directly into modified adjusted gross income. A large conversion executed in the same year the couple is relying on the $6,000 senior deduction can push MAGI above the $150,000 phase-out threshold and claw part of that deduction back. The phase-out is gradual, not a cliff, so careful sizing of each conversion can preserve most or all of the benefit. But the interaction is real, and ignoring it means overpaying taxes while thinking the math is working in your favor. Running the numbers with a tax professional before converting is essential, not optional.

Three Tax Moves Before Social Security Begins

1. Bracket-fill Roth conversions every year through age 69. Converting traditional IRA dollars to a Roth and stopping at the top of the 12% bracket locks in today’s rate, shrinks future RMDs, and gives the surviving spouse a tax-free bucket once filing status shifts to single. This is the highest-value lever available in this scenario, provided conversions are sized to stay below the $150,000 MAGI threshold that triggers the senior deduction phase-out.
2. Hold the line on delaying Social Security to 70. Each year of delay past full retirement age adds roughly 8% to the eventual benefit, and that larger check also becomes the survivor benefit later. Claiming early to “protect” the pension misreads the underlying math.
3. Confirm how the Social Security Fairness Act changes the teacher’s benefit estimate. President Biden signed the Social Security Fairness Act on January 5, 2025, permanently repealing both the Windfall Elimination Provision and the Government Pension Offset. The Social Security Administration began applying the repeal to existing recipients in February 2025. Neither provision any longer reduces benefits for workers with non-covered pensions, so the teacher should pull a current estimate directly from SSA.gov before building any plan around a number, because the repeal may materially increase the household’s projected lifetime Social Security income.

The Near-Term Checklist for This Couple

Start with the Social Security statement. Because WEP and GPO have been permanently repealed, the couple should rely on current SSA estimates rather than any older projections built around pension offsets. Next, model a Roth conversion sized to fill the 12% bracket for tax year 2026, keeping an eye on the MAGI threshold for the senior deduction, then repeat the exercise each year through 2029.

The inflation backdrop makes that discipline more urgent. The Bureau of Labor Statistics reported that the CPI-U rose 4.2% year-over-year in May 2026, the sharpest annual pace since April 2023, driven largely by an energy cost spike tied to disruption in global oil markets. By June 2026, the annual rate pulled back to 3.5%, and by July and August it held steady at 3.4%. Gasoline averaged $4.35 per gallon in August and was up 27.4% from a year earlier, accounting for more than one-third of the monthly all-items increase. The broader energy index rose 16.3% over the same 12-month period. For retirees drawing fixed pension income, that sustained pressure on purchasing power is a direct argument for locking in tax efficiency through Roth conversions while the window is open.

Editor’s note: This revision added the OBBB senior deduction’s complete phase-out threshold ($250,000 MAGI for joint filers) and a new section explaining how Roth conversions can claw back that deduction by pushing MAGI above the $150,000 phase-out start. It also added the signing date and implementation timeline for the Social Security Fairness Act, confirmed the August 2026 average gasoline price of $4.35 per gallon from BLS data, and included the broader energy index annual increase of 16.3% alongside the previously reported 27.4% gasoline figure.
