Required Minimum Distributions (RMDs)

Required Minimum Distributions force retirees to withdraw from tax-deferred accounts (Traditional IRA, 401k, 403b) starting at age 73. The penalty for missing an RMD is 25% of the shortfall — among the harshest in the tax code. Strategic management can dramatically reduce lifetime tax.

When RMDs start

If you delay the first RMD to the April 1 deadline, you must take TWO RMDs that year — both could push you into a higher tax bracket.

How to calculate your RMD

RMD = Account balance (Dec 31 prior year) ÷ Distribution period from IRS Uniform Lifetime Table

AgeDistribution periodRMD as % of balance
7326.53.77%
7524.64.07%
8020.24.95%
8516.06.25%
9012.28.20%
958.911.24%

Example: $500,000 IRA balance at end of prior year, age 75. RMD = $500,000 / 24.6 = $20,325. Must withdraw at least this amount by Dec 31.

What accounts require RMDs

The 25% missed-RMD penalty

If you miss your RMD, the IRS imposes a 25% excise tax on the SHORTFALL (not the entire account):

If you discover a missed RMD, take the distribution immediately and file Form 5329 with explanation.

Qualified Charitable Distributions (QCDs)

If you're 70½ or older AND charitably inclined, QCDs are one of the most tax-efficient strategies:

Available even if you don't itemize — major advantage post-2017 tax law that doubled standard deduction.

Strategic RMD reduction tactics

  1. Roth conversions before age 73: Convert Traditional IRA balances to Roth in years before RMD starts. Pay tax now at potentially lower rate, eliminate future RMDs.
  2. QCDs as RMD substitute: If you donate to charity anyway, route through QCD instead of RMD-then-donate.
  3. QLAC (Qualified Longevity Annuity Contract): Allocate up to $200,000 to QLAC; that portion is exempt from RMDs until annuity payments start (up to age 85).
  4. Working past 73 (for 401k only): If still working at your employer at 73+, you can defer RMDs from THAT employer's 401k until you separate. Doesn't apply to IRAs.
  5. Roth 401k rollover to Roth IRA: Roth 401k now requires RMDs (changed by SECURE 2.0 — wait, actually SECURE 2.0 ELIMINATED Roth 401k RMDs starting 2024). So Roth 401k now has no RMDs either, like Roth IRA.

Frequently Asked Questions

What's the deadline for taking my RMD?
December 31 of the calendar year. EXCEPTION: your FIRST RMD can be delayed until April 1 of the year after you turn 73 (but you'd then take 2 RMDs that year).
How is RMD calculated for inherited IRAs?
Different rules. Spouse inheriting can roll into own IRA and use normal rules. Non-spouse inheriting (post-2019) generally must withdraw entire balance within 10 years (10-year rule), with annual RMDs in years 1-9 if original owner was already taking RMDs.
Can I take more than my RMD?
Yes. RMD is the MINIMUM. You can withdraw more anytime, but excess withdrawals don't count toward future-year RMDs.
What if I have multiple IRAs?
Calculate RMD for each IRA separately, but you can take the TOTAL combined RMD from any single IRA (or any combination). Different rule for 401ks: each 401k's RMD must come from that specific 401k.
Are RMDs taxed?
Yes — as ordinary income. They're a major reason retirees can end up in higher tax brackets than during working years (combined with Social Security and pension income).
