Financial Planning for Rolling Retirement Dates

Introduction

Rolling retirement (also called phased or partial retirement) means moving from full-time work to a reduced schedule or intermittent work over months or years instead of stopping work all at once. Planning for rolling retirement requires a different playbook than a single retirement date because income sources, benefit timing, tax strategies, and healthcare coverage can all shift across the transition. This article gives a practical, up-to-date guide (2025) to plan a rolling retirement, including timing Social Security, managing withdrawals, and reducing longevity and tax risks.

Why rolling retirement changes the math

Most traditional retirement plans assume one stop-start date. Rolling retirement changes three core variables:

• Timing of guaranteed benefits (Social Security, pensions).
• Pattern of taxable and tax-advantaged withdrawals (IRAs, 401(k)s).
• Health insurance and Medicare eligibility timing.

Because these variables interact, a small change—working two extra years at reduced hours, or delaying Social Security by a year—can materially change lifetime income and required withdrawal strategies (Social Security Administration; IRS). The planning emphasis shifts from a single forecast to scenario-based decision making.

Key planning areas and updated rules to know (2025)

• Social Security benefits grow if you delay past your full retirement age (FRA) until age 70; delayed retirement credits increase benefits roughly 8% per year between FRA and 70 for most birth cohorts (Social Security Administration). Consider partial work while delaying benefits to maximize lifetime income.
• Medicare eligibility starts at 65 for most people, but employer coverage, COBRA, or marketplace plans can affect costs if you reduce hours before 65 (Centers for Medicare & Medicaid Services).
• Required Minimum Distributions (RMDs): SECURE 2.0 changed RMD rules; the RMD age is 73 for most taxpayers through 2032 and will increase to 75 beginning in 2033 for younger cohorts. Follow IRS guidance for your birth year and account type (Internal Revenue Service).
• Withdrawal guidance such as the 4% rule are useful starting points but must be adapted to phased-work income and changing expenses; see our article on The 4% Rule of Retirement Withdrawal for context.

A step-by-step planning process for rolling retirement

1. Inventory your assets, liabilities, and recurring expenses

• List balances for taxable brokerage accounts, 401(k)/403(b), IRAs, pensions, annuities, and non-retirement assets.
• Estimate fixed and discretionary annual expenses and expected inflation assumptions (2–3%+ realistic for long horizons).

1. Model multiple retirement-entry scenarios

• Build at least three scenarios: early phased retirement (start part-time 2–5 years early), on-time gradual retirement at your expected date, and delayed retirement (full hours until later). Run worst-, base-, and best-case market/health scenarios.

1. Sequence withdrawals and tax planning

• If you can work part-time and delay Social Security, use taxable accounts first to preserve tax-advantaged balances and potentially allow Roth conversions at lower tax rates during years with lower earned income.
• Use Roth conversions selectively to reduce future RMDs and taxable income in later years (IRS rules apply). Coordinate conversions with expected income from part-time work and any pension start dates.

1. Coordinate Social Security timing

• Delay benefits if you expect long life expectancy and can cover living costs through earnings or savings. Delaying to age 70 gives the maximum monthly benefit for most claimants, but partial work while delaying can be a powerful hybrid strategy.
• Check spousal and survivor implications before delaying — benefits and survivor income depend on claim timing (Social Security Administration).

1. Calibrate withdrawals to reduce sequence-of-returns risk

• When leaving full-time work, consider a conservative initial withdrawal rate and a flexible spending plan. A dynamic withdrawal approach lets you reduce spending after poor market years and step up withdrawals in strong markets.
• See our piece on Dynamic Retirement Withdrawal Strategy for examples and tools.

1. Review health insurance and long-term care exposure

• If you reduce hours before age 65, plan for how you’ll cover medical premiums—employer coverage, COBRA, or marketplace plans. Account for potential long-term care needs and how they might be funded.

1. Revisit estate and beneficiary plans

• Update beneficiaries, durable power of attorney, and advanced healthcare directives when your household or income structure changes.

Practical examples (realistic scenarios)

• 
  

  Example 1 — Jim (works part-time, delays Social Security)
  
  Jim transitions to 60% hours at 62 and delays Social Security to 68. He uses a mix of taxable account withdrawals and part-time earnings to cover living expenses and performs limited Roth conversions in low-income years. Delaying Social Security increased his monthly benefit and reduced the need to draw from tax-advantaged retirement accounts early, improving portfolio longevity.

  
  
• 
  

  Example 2 — Sarah (part-time while contributing)
  
  Sarah starts part-time work at 63 and continues to contribute to her 401(k) through an employer who permits pro-rata contributions. She reduces equity exposure slightly and tilts to income-producing assets to cover cash needs, lowering her near-term withdrawal risk.

  
  

These scenarios show how rolling retirement lets you shift the timing of benefits and withdrawals to improve lifetime outcomes when planned intentionally.

Withdrawal guidance and a conservative reference table

Withdrawal rates must be individualized. As an illustration only, here are conservative starting withdrawal-rate ranges tied to common phased-retirement ages (not investment advice):

*These numbers are illustrative starting points. Adjust for portfolio mix, future healthcare costs, and your risk tolerance. See our coverage of The 4% Rule of Retirement Withdrawal for deeper context.

Tax and IRA considerations during phased work

• Earnings put you in taxable brackets; plan Roth conversions in low-income years to smooth taxable income across retirement.
• Employer plans: if you keep contributing to a 401(k) while working part-time, check eligibility rules; small-business owners can use SEP or SIMPLE IRAs for extra contributions (IRS).
• Be mindful of the tax interaction between withdrawals and Social Security taxation — higher provisional income can make more of Social Security taxable (Social Security Administration; IRS).

Common mistakes to avoid

• Treating rolling retirement like a single-date retirement: this can produce gaps in coverage and cash flow.
• Ignoring Medicare timing: a coverage gap before 65 can be expensive.
• Overconfident withdrawal assumptions: failing to test low-return sequences puts capital at risk.
• Neglecting spouse-survivor planning: staggered claim dates can change survivor income materially.

Tools, professionals, and resources

• Use cash-flow modeling software or a financial planner who models multiple scenarios and Monte Carlo simulations.
• Consult the Social Security Administration for benefit estimates and spousal rules (ssa.gov) and the IRS for RMD and rollover rules (irs.gov).
• Read practical consumer guidance from the Consumer Financial Protection Bureau on retirement choices (consumerfinance.gov).

Action checklist (next 6–12 months)

• Run a baseline cash-flow model comparing 3 retirement-entry ages.
• Identify low-income years where Roth conversions make sense.
• Check employer rules for part-time contributions and health benefits.
• Decide whether you can delay Social Security and by how long.
• Update beneficiaries and legal documents.

Closing thoughts

Rolling retirement can offer a better balance between income, purpose, and longevity protection when it’s planned intentionally. The key is scenario planning: model the interactions of part-time earnings, benefit timing, withdrawals, taxes, and health insurance. Small tactical decisions—when and how to take Social Security, which accounts to tap first, how much to convert to Roth—add up over a multi-year phased transition. Work with a qualified planner to stress-test your plan and stay flexible as life or markets change.
