Executive summary

Updated to August 2026: Mark (68) and Elaine (66) continued their staged Roth conversions, kept a $100,000 deferred‑income annuity structured to meet typical QLAC guidance, and preserved delayed Social Security and pension survivor protections. By mid‑2026 they had removed roughly $220,000 from the RMD base and increased their Roth pool to about $240,000, smoothing taxable income in the short term and improving late‑life cash flow and legacy flexibility.

Background: who they are and why this mattered

Mark and Elaine Rivera are a representative retired couple navigating the interactions of RMDs, Medicare premium rules and estate goals in 2026. Their situation is common: a significant traditional IRA built from rollovers and earlier business sale proceeds, a modest defined‑benefit pension, some taxable savings and a small Roth balance.

  • Ages in 2026: Mark 68, Elaine 66.
  • Assets before actions (2024 baseline): traditional IRAs & rolled 401(k) ≈ $1.3M; Roth IRAs $40,000; taxable brokerage $150,000; public school pension ≈ $28,000/year.
  • Primary goals: reduce the taxable shock from RMDs that begin at 73 for many retirees, avoid higher Medicare IRMAA surcharges, preserve survivor income and leave tax‑efficient assets to heirs given the 10‑year distribution rule for many beneficiaries.

Challenge

The Riveras faced three tightly linked problems: (1) a large tax‑deferred balance that would drive RMDs—and income taxes—after age 73; (2) the chance that large conversions bunched into single years could trigger higher marginal tax rates and Medicare IRMAA surcharges; and (3) the question of how to leave assets in the most tax‑efficient form for heirs under current distribution rules.

The planning challenge was sequencing: how to pay enough tax now to shrink the RMD base without overpaying in any one year, and how to add durable late‑life income without surrendering too much liquidity or taking excessive counterparty risk with an insurer.

Solution: three coordinated moves (revisited for Aug 2026)

The Riveras used a coordinated toolkit: staged Roth conversions during low‑income years, a deferred income annuity inside the IRA structured to align with QLAC principles, and Social Security/pension timing to preserve guaranteed lifetime income. Two developments between 2024–2026 shaped execution:

  • Advisers and plan providers standardized documentation and product menus for QLAC‑style deferred income annuities in 2025–26, making plan‑based purchases and IRA placements operationally simpler.
  • More advisers used tax‑scenario software that models RMDs, Roth conversion timing, and IRMAA impacts together—improving multi‑year sequencing decisions.
  1. Staged Roth conversions. Rather than converting a lump sum, the Riveras continued converting slices of their traditional IRA in 2024–2026 and paused conversions in years when projected MAGI neared IRMAA triggers. The staged approach kept conversions inside lower brackets and spread tax payments.
  2. Purchased a QLAC‑style deferred income annuity (DIA) inside the IRA. They kept the contract set to begin payments at age 85—removing the purchase amount from the RMD calculation through age 84—and selected a product with a modest inflation rider and a conditional survivor benefit. They accepted limited liquidity in exchange for longevity insurance and RMD relief in their 70s.
  3. Coordinated benefit timing. Mark delayed Social Security to 70 to maximize guaranteed income; Elaine chose a pension survivor election that balanced current cash needs with survivor protection.

Why this mix still makes sense in 2026

  • Roth conversions permanently shrink the tax‑deferred base and provide tax‑free growth and distributions—valuable when many non‑spousal beneficiaries face compressed distribution windows.
  • QLAC‑style deferred annuities shift RMD exposure to later years and directly insure longevity risk, which is difficult to replicate cheaply in the market.
  • Delaying Social Security remains an efficient, inflation‑protected source of guaranteed income that is not an RMD and reduces the need to withdraw from IRAs during conversion years.

Implementation: timeline, numbers and decision logic (updated through Aug 2026)

  1. 2024–2026: Roth conversions totaling $150,000 (unchanged plan), executed in slices. Conversions were $40k (2024), $60k (2025), $50k (2026). The adviser modeled alternative market returns, tax‑bracket sensitivity and IRMAA impacts; conversions were sized to avoid jumping into materially higher Medicare premium brackets.
  2. Late 2025: $100,000 QLAC‑style DIA purchased inside the IRA. Structured to begin at 85, the DIA met common plan documentation and provider practices that many advisers used in 2025–26 to qualify for RMD exclusion through age 84. The couple accepted a limited inflation rider (approximately 1–1.5% annual adjustments) to balance cost and real income.
  3. 2026 cash‑flow management. They used taxable brokerage proceeds to pay the year‑of‑conversion taxes to avoid selling core IRA holdings and to avoid triggering capital gains in a down market. Annual budgets were adjusted so conversions did not create liquidity strain.
  4. Governance and reviews. The adviser scheduled annual tax‑model refreshes and insurer due diligence (credit ratings, reserve practices) to monitor counterparty risk on the DIA.

Results: measured change as of August 2026

  • RMD base reduction: Conversions plus the DIA reduced the IRA balance counted for RMDs in a pre‑RMD projection by roughly $220,000 compared to the 2024 baseline—about a 17% decrease in the tax‑deferred pool that would otherwise drive RMDs at 73.
  • Smoothing taxable income and IRMAA avoidance: Because conversions were staged and taxes paid from taxable accounts, the couple avoided bumping into higher marginal brackets in conversion years. The adviser’s projections estimated Medicare premium (IRMAA) increases avoided of roughly $6,000–$9,000 per year across ages 69–73, depending on future income movements.
  • Roth growth and legacy value: The Roth account grew from $40,000 in 2024 to about $240,000 by August 2026 (conversions plus conservative market growth). That left a larger tax‑free pool for flexible withdrawals and a cleaner legacy under the 10‑year rule for many beneficiaries.
  • Late‑life protection: The DIA purchase provides a guaranteed income floor beginning at 85, reducing the couple’s concern about outliving assets; combined with Mark’s delayed Social Security, their projected guaranteed income replaces a higher share of essential costs in very late life.

Costs and tradeoffs remain real: the Riveras paid roughly $25,000–$45,000 in incremental federal and state taxes on conversions through 2026 (net of standard deductions and brackets), accepted limited liquidity for the DIA funds, and assumed insurer counterparty risk. Their adviser’s multi‑scenario ROI models showed the tax cost was justified by reduced lifetime taxes in many—but not all—scenarios, particularly those where markets underperform or longevity is above average.

Lessons learned—what to apply to your planning

  • Run integrated multi‑year models—not single‑year rules of thumb. RMDs, Roth conversions and IRMAA interact nonlinearly. Use software or a fiduciary who models 10–30 year scenarios with alternate market and health outcomes.
  • Use taxable assets to pay conversion taxes if possible. Paying conversion tax from a taxable account preserves IRA principal and reduces the chance of needing large taxable IRA distributions later.
  • Vet annuity contract details carefully. Confirm start date, inflation indexing, survivor options, liquidity riders and precisely how the product is treated for RMD purposes. Insurer credit strength matters—review ratings and reserving practices.
  • Cap conversions to avoid IRMAA cliffs. Small, repeatable conversions in low‑income windows usually outperform big, single‑year conversions that trigger premium surcharges or jump tax brackets.
  • Consider state tax rules. Some states continue to tax Roth conversions differently or have unique treatment of annuity payouts—include state tax in your models.

Takeaways

  • Targeted, staged Roth conversions can materially reduce future RMDs and create a tax‑efficient legacy, but only when timed and sized to minimize short‑term tax and IRMAA costs.
  • A QLAC‑style deferred income annuity can remove dollars from the RMD calculation through the deferral window and provide late‑life income insurance—contract specifics and insurer strength matter.
  • Delaying Social Security continues to be a simple, low‑cost way to raise guaranteed lifetime income and support conversion sequencing.
  • Pay conversion taxes from non‑qualified sources when feasible to preserve IRA balances and avoid perverse sequencing effects.
  • Update models annually—policy, market and premium thresholds change, and the right plan in 2024 may need adjustments by 2026 or later.

Caveats and next steps

  • This is one couple’s path. Your situation—health, life expectancy, state taxes, liquidity needs and family goals—may point to different choices.
  • Check current Medicare IRMAA brackets and federal tax brackets for 2026 before sizing conversions; both are indexed and can shift year to year.
  • Confirm QLAC/DIA contract language and whether an IRA or employer plan accepts the product under current plan documents. Insurer practices evolved in 2025–26, but product terms still vary widely.
  • Work with a fiduciary adviser and tax professional who will run multi‑scenario ROI analyses, including worst‑case market returns and longer life expectancy scenarios.

FAQ

Will Roth conversions always reduce my lifetime taxes?

Not always. Roth conversions require paying tax now; if you expect much lower taxable income in retirement, heirs in low tax brackets, or shorter life expectancy, conversions may not pay off. Use multi‑year after‑tax income modeling to compare tax‑now vs tax‑later outcomes across scenarios.

Do all deferred income annuities remove money from RMD calculations?

No. Only contracts that meet QLAC‑style treatment under plan and IRA documentation are typically excluded from the RMD base through the deferral window. Product terms, purchase timing and plan acceptance matter—confirm in writing with your custodian and insurer.

How should I size conversions to avoid IRMAA surcharges?

Run reverse‑engineered scenarios: determine the MAGI/thresholds that would trigger IRMAA increases in the year you’d convert, then size conversions below those cliffs if possible. If you can’t stay below thresholds, consider spreading conversions over additional years and paying tax from taxable accounts to smooth MAGI.

Is delaying Social Security always the right call to support conversion strategies?

Delaying Social Security increases guaranteed income and can reduce the need to withdraw from IRAs during conversion windows, but it’s not universally optimal. Consider health, spousal survival goals, current cash needs and breakeven ages. Integrate Social Security timing into your multi‑scenario plan rather than treating it separately.

What red flags should make me pause before buying a DIA/QLAC product?

Be cautious if the contract lacks clear start dates, inflation protection options, credible survivor benefits, or if the insurer has weak financial ratings. Also avoid products that lock up funds without any liquidity without a clear, modeled benefit to your lifetime income plan.
