Retirement planning becomes decisively tactical between your mid-50s and mid-70s. This 55–75 year-by-year guide walks through the concrete steps you should take to turn balances in 401(k)s, IRAs and Roth IRAs into reliable, tax-efficient income—while coordinating pensions and Social Security and managing required minimum distributions (RMDs).

What this guide covers

  • Clear milestones and actions for each age band (55–59½, 59½–62, 62–67, 67–70, 70–73, 73+)
  • Account-consolidation and rollover decision points for 401(k) vs IRA vs Roth
  • How pensions and Social Security choices affect taxes and income timing
  • RMD basics you must know (as of mid-2026) and practical steps to manage them
  • Checklists you can follow with your adviser or DIY

Key facts to start with

  • Required minimum distributions: as of June 2026, most retirees must begin RMDs at age 73. RMDs apply to traditional IRAs and tax-deferred employer plans (401(k), 403(b), etc.).
  • Roth IRAs: original-owner Roth IRAs are not subject to RMDs; Roth 401(k) accounts are subject to RMDs unless rolled to a Roth IRA.
  • Social Security: full retirement age varies by birth year; delaying benefits beyond full retirement age up to age 70 increases benefits via delayed retirement credits (roughly 8% per year in U.S. rules).
  • Pensions: choices (lump sum vs annuity) affect long-term taxes and flexibility; treat pension cashouts as a major taxable decision to analyze with a planner.

Before you begin: a quick inventory

Start with a complete, current inventory. This single document drives every decision below.

  • List each account: 401(k) plans (with plan name and contact), IRAs, Roth IRAs, taxable brokerage, pensions (benefit amount and payout options), and expected Social Security estimated benefit.
  • Record balances, cost-basis for taxable, investment options and fees, employer match vesting status, loan balance and in-service withdrawal rules.
  • Identify any employer-plan unique features: in-plan Roth conversion, access to annuity options, or if the plan allows continuing deferral of RMDs when still working.

Age 55–59½: De-risk tactical and preserve flexibility

Primary goal: stop leaving avoidable fees or lost options on the table while establishing withdrawal flexibility.

  • Confirm any in-plan protections: if you retire after 55, some plans allow penalty-free withdrawals from the 401(k) under the “age 55” rule—note this is plan-specific and not available in IRAs.
  • If still working, maximize employer match and capture any catch-up contribution options available at your plan’s rules.
  • Consider beneficiary designations: name contingent beneficiaries and check for retirement-account beneficiary mistakes that can create taxable events down the line.
  • Start a retirement income buffer in taxable or Roth accounts: having 1–3 years of cash or short-term bonds outside tax-deferred accounts lets you avoid selling tax-deferred assets during a market downturn.

Age 59½–62: Establish distribution sources and tax buckets

Primary goal: build a tax-efficient layering of future income sources to give flexibility when you claim Social Security and access pensions.

  • At 59½, IRA/401(k) distributions are penalty-free. Use this milestone to test withdrawal logistics and tax withholding for planning purposes.
  • Create separate “tax buckets”: taxable account (short-term buffer and capital gains management), traditional tax-deferred (401(k)/IRA) and Roth (tax-free growth). Aim to hold assets according to where they’re most tax-efficient—see the Asset-Location section below.
  • If you have a pension lump-sum offer, assemble the numbers: actuarial equivalent, inflation adjustments, survivor options and how the lump sum would be invested and taxed. Don’t decide without a scenario analysis.

Age 62–67: Social Security choices and taxable-income planning

Primary goal: map Social Security claiming to taxable-income expectations and Medicare enrollment timing.

  • Run Social Security claiming scenarios: early (as early as 62), full retirement age (varies by birth year) and delayed to 70. Compare present value and non-financial priorities (health, employment plans).
  • Project taxable income for the years between retirement and age 70: will you need to draw from 401(k)/IRA early, or can you fund spending from taxable or Roth sources? Lower taxable income years are valuable—document them.
  • Medicare and IRMAA: anticipate Medicare Part B and D income-related adjustments. High withdrawals before Medicare enrollment can raise premiums later.

Age 67–70: Maximize flexibility, prepare for RMDs

Primary goal: make final structural choices before RMDs begin at 73; firm up pension/annuity decisions and finalize beneficiary/estate items.

  • Finalize pension decision: if offered a lump sum and you desire rollover flexibility, you can roll to an IRA—but evaluate the loss of plan-level protections (e.g., anti-alienation/ERISA creditor protections) versus investment choice gains.
  • Roth accounts: consider consolidating Roth 401(k) balances to Roth IRAs if you want to avoid Roth 401(k) RMDs. This is a transactional step, not necessarily a tax-planning conversion strategy.
  • Confirm how your retirement pay sources layer with Social Security: a modest taxable income in early retirement preserves the option to delay Social Security to increase lifetime benefits.

Age 70–73: Final prep and claim deadlines

Primary goal: if you intend to delay Social Security to age 70, make that claim; prepare for RMD mathematics and set systems to manage distributions.

  • Claim Social Security if delaying to 70 is your plan—benefits stop growing at 70.
  • Set up RMD-calculation systems now: confirm birthdate, account balances as of Dec. 31 each year, life-expectancy factor (Uniform Lifetime Table), and whether aggregation rules apply to your mix of IRAs and employer plans.
  • Coordinate beneficiary review: RMDs in future can be minimized for heirs by having Roth IRAs as a share of estate, because original-owner Roth IRAs are not subject to RMDs.

Age 73+: Manage RMDs and tax-aware withdrawals

Primary goal: execute RMDs properly, control marginal tax rates, and preserve legacy options.

  • Calculate and withdraw RMDs by Dec. 31 each year (failure to take the full RMD can incur a severe excise tax). For the first RMD, you may be allowed to delay to April 1 of the following year—be careful of two-RMD-years with tax consequences.
  • Remember aggregation rules: traditional IRAs can be aggregated for RMD withdrawal purposes (you may withdraw the total required amount from one or more IRAs). Employer plans (401(k) etc.) calculate RMDs separately and cannot be aggregated with IRAs unless rolled into an IRA.
  • Work with your tax preparer to smooth taxable income: consider withholding, estimated taxes, or partial Roth conversions only if they fit your long-term tax plan (consult a tax professional). Avoid panicked large withdrawals in response to market swings.

Asset-location rules of thumb

Allocation matters not just for returns but for taxes when you retire. Use these general rules:

  • Hold high-growth, high-variance investments (e.g., U.S. equities) in Roth accounts when feasible—tax-free growth reduces future RMD-related taxes.
  • Keep income-producing, lower-growth assets (bonds, REITs) in taxable or tax-deferred accounts depending on your tax bracket and RMD exposure.
  • Use taxable accounts strategically for short-term spending needs and for harvesting long-term capital gains in low-income years.

Common decision checklists

Should you roll a 401(k) into an IRA?

  • Pros: more investment options, consolidated management, easier Roth rollovers to Roth IRA.
  • Cons: potential loss of some creditor protections, possible plan-based in-service withdrawal rules, and losing ability to delay RMDs if still working for that employer and over RMD age.
  • Checklist: compare fees, investment options, creditor protections, and whether the plan allows continuing deferral past RMD age if you stay employed.

Should you move Roth 401(k) to Roth IRA?

  • If you want no RMDs on Roth balances, rolling a Roth 401(k) to a Roth IRA avoids Roth 401(k) RMDs.
  • Ensure rollovers follow plan rules and that beneficiary designations are updated.

Sample scenario: how sequencing choices matter

Example (illustrative): Maria, age 64 in 2026, has a $600,000 401(k), $150,000 traditional IRA, $80,000 Roth IRA and a small pension option. She plans to retire at 66 and delay Social Security to 70.

  • Actions: At 65 she rolls her 401(k) into an IRA to consolidate (after confirming plan loan handling and creditor protections). She maintains a 2-year taxable buffer to fund 66–67 spending.
  • At 66–69 she uses taxable and Roth IRA funds for spending to keep taxable income low while deferring Social Security to 70.
  • At 70 the Social Security benefit rises; RMDs begin at 73. Because Maria has a Roth IRA (no RMDs), her mandatory withdrawals come mostly from the traditional IRA/rolled 401(k), reducing taxable pressures on Social Security benefits when RMDs begin.

This scenario illustrates inventory, reallocation and timing; your numbers and choices will differ, but the process (inventory—consolidate—create buffers—coordinate Social Security—prepare for RMDs) is repeatable.

Common mistakes to avoid

  1. Failing to inventory beneficiary designations and letting a default IRA beneficiary conflict with estate documents.
  2. Assuming all Roth accounts behave the same: Roth 401(k)s have RMDs, Roth IRAs do not.
  3. Taking large taxable withdrawals in a single year and pushing you into a higher bracket or IRMAA thresholds for Medicare premiums.
  4. Missing plan-specific rules—some 401(k) plans allow continued deferral of RMDs if you’re still employed at the plan sponsor past RMD age.

Action checklist to start today

  • Create an account inventory and a one-page retirement-income map showing when RMDs, pensions, and Social Security begin.
  • Ask your 401(k) administrator for plan-specific rules (in-plan Roth, loans, RMD deferral if still employed, in-service distributions).
  • Set up a 2–3 year taxable and/or Roth buffer for early retirement years to preserve flexibility.
  • Confirm Medicare enrollment dates and project IRMAA exposure with your tax preparer.
  • Review pension options with an actuary or fiduciary adviser before electing lump sum vs lifetime benefit.

When to consult a professional

This guide gives a framework, but two situations call for professional help:

  • Complex plan rules, large pension lump-sum offers, or concentrated company stock positions.
  • Tax-sensitive strategies that interact with Medicare IRMAA, large Roth conversion sums (if considering conversions), or estate-design considerations.

Final note

Decades of retirement income depend on choices you make between ages 55 and 75. If you systematically inventory accounts, build tax-aware spending buckets, coordinate Social Security timing to your income needs, and put systems in place for RMDs, you convert complexity into manageable steps. Use this guide as your checklist—then validate the biggest moves with a qualified planner or tax advisor.
