At what age should I start planning for RMDs?

Ideally, begin planning in your late 50s or early 60s. The Roth conversion window typically spans from retirement (income drops) to age 73 (when RMDs begin and income rises again). Waiting until 70 or 71 leaves fewer years for conversions. Even 2–3 years of strategic conversions can meaningfully reduce the RMD burden.

Can I convert my full IRA to Roth before RMDs start?

Yes, with no dollar limit on Roth conversions. The constraint is taxes — you pay ordinary income tax on the full conversion amount in the year of conversion. Converting too aggressively in one year can push you into the 32%, 35%, or 37% bracket. Gradual conversions over multiple years, filling up to the top of the 22% or 24% bracket, is usually more tax-efficient than a single large conversion.

If I roll my 401(k) to an IRA at retirement (age 65), when do IRA RMDs start?

IRA RMDs start at age 73 (or 75 if born in 1960 or later) regardless of when the rollover occurred. Rolling to an IRA at 65 starts the 8-year window before mandatory distributions — ideal for Roth conversions at lower rates.

Rollover Strategy Before RMDs Begin — Optimize Your Accounts Before Age 73

What IRA rollover and optimization strategies should I consider before RMDs begin?

The years between retirement and the start of RMDs — often ages 60–72 — represent a unique planning window. Income may be lower than peak earning years and lower than future RMD years, making it ideal for Roth conversions, account consolidation, and strategic rollovers.

Taking advantage of this window can reduce future RMD amounts, lower lifetime taxes, and improve estate planning outcomes.

Key RMD Rules

1Roth conversions before RMDs begin reduce future RMD balances — every dollar converted is no longer subject to mandatory distribution.
2IRA consolidation: rolling multiple IRAs into one simplifies administration, reduces the risk of missing an account, and may reduce fees.
3401(k) to IRA rollover: enables QCD strategy (QCDs cannot be made from 401(k)s) and broadens investment options.
4Consider keeping a 401(k) at a former employer if you are still working — the still-working exception applies only to the current employer's plan.
5Evaluate rolling old 401(k)s into the current employer's 401(k) if the plan accepts rollovers and you want to extend the still-working exception.
6IRMAA planning: large Roth conversions spike MAGI the conversion year — balance the Roth conversion tax benefit against potential IRMAA surcharges.

The Pre-RMD Roth Conversion Strategy

If you retire at 65 and RMDs begin at 73, you have 8 years of relatively low income. Each year, calculate how much you can convert to Roth while staying within your target bracket (often 22% or 24%). Conversion reduces the traditional IRA balance, reducing future RMDs. By age 73, the RMD on a $500,000 IRA (at factor 26.5) is $18,868 — but the RMD on a $200,000 IRA after conversions is only $7,547. The tax paid on conversions is often lower than the ordinary income tax that would have been paid on larger future RMDs — especially if Social Security and IRMAA effects are considered.

Account Consolidation: Simplify Before RMDs

Many retirees accumulate IRAs at multiple institutions over decades. Consolidating into fewer IRAs simplifies: (1) Annual RMD calculation — fewer balances to track; (2) Investment management — fewer logins and statements; (3) Beneficiary administration — fewer designation forms to maintain; (4) QCD eligibility — only IRAs can make QCDs, so consolidating into an IRA improves QCD access. The optimal setup for most retirees: one traditional IRA (for QCDs and RMDs), one Roth IRA (for tax-free growth), and optionally a taxable brokerage account.

Common RMD Mistakes to Avoid

⚠Missing the Roth conversion window — waiting until RMDs begin makes conversions less efficient because the RMD must be taken first (and cannot be rolled to Roth).
⚠Rolling a 401(k) to an IRA while still employed past 73 — this eliminates the still-working exception and triggers IRA RMDs.
⚠Consolidating IRAs without considering state-specific creditor protection differences between 401(k) plans and IRAs.
