-nan Required Minimum Distributions force you to withdraw money from Traditional retirement accounts starting at age 73 — whether you need the income or not. How you handle RMDs can mean the difference between a manageable tax bill and an unnecessarily large one. The best RMD strategy starts years before your first distribution is due.
What Are Required Minimum Distributions?
RMDs are the IRS’s way of collecting tax revenue on money that’s been growing tax-deferred in Traditional 401(k)s, IRAs, and similar accounts. You got a tax break when you contributed; now the government wants its share.
| Account Type | RMDs Required? | Starting Age | Notes |
|---|---|---|---|
| Traditional IRA | Yes | 73 (75 in 2033) | Can aggregate — take from any IRA |
| Traditional 401(k) | Yes | 73 (75 in 2033) | Must take from each 401(k) separately |
| Roth IRA | No | Never | No RMDs for original owner |
| Roth 401(k) | No | Never (since 2024) | SECURE 2.0 eliminated Roth 401(k) RMDs |
| SEP IRA | Yes | 73 | Same rules as Traditional IRA |
| SIMPLE IRA | Yes | 73 | Same rules as Traditional IRA |
| 403(b) | Yes | 73 | Similar to 401(k) rules |
| Inherited IRA | Yes | Varies | 10-year rule for most non-spouse beneficiaries |
See Required Minimum Distributions for the detailed IRS rules.
RMD Age Timeline
| Birth Year | RMD Starting Age | First RMD Due By |
|---|---|---|
| 1950 or earlier | 72 (already started) | Already past |
| 1951-1959 | 73 | April 1 of year after turning 73 |
| 1960-1962 | 73 | April 1 of year after turning 73 |
| 1963-1965 | 75 (starting 2033+) | April 1 of year after turning 75 |
| 1966+ | 75 | April 1 of year after turning 75 |
Important timing trap: Your first RMD can be delayed until April 1 of the following year. But if you delay, you’ll take two RMDs in that second year (the delayed first one plus the current year’s). That double distribution could push you into a higher tax bracket. Most advisors recommend taking your first RMD in the year you turn 73, not the following year.
How to Calculate Your RMD
The formula is straightforward:
RMD = Account Balance (Dec 31 prior year) ÷ Life Expectancy Factor
2026 RMD Life Expectancy Factors (Uniform Lifetime Table)
| Age | Factor | RMD % of Balance | RMD on $500K | RMD on $1M |
|---|---|---|---|---|
| 73 | 26.5 | 3.77% | $18,868 | $37,736 |
| 74 | 25.5 | 3.92% | $19,608 | $39,216 |
| 75 | 24.6 | 4.07% | $20,325 | $40,650 |
| 76 | 23.7 | 4.22% | $21,097 | $42,194 |
| 77 | 22.9 | 4.37% | $21,834 | $43,668 |
| 78 | 22.0 | 4.55% | $22,727 | $45,455 |
| 79 | 21.1 | 4.74% | $23,697 | $47,393 |
| 80 | 20.2 | 4.95% | $24,752 | $49,505 |
| 85 | 16.0 | 6.25% | $31,250 | $62,500 |
| 90 | 12.2 | 8.20% | $40,984 | $81,967 |
If your spouse is your sole beneficiary and is more than 10 years younger, use the Joint Life Expectancy Table instead (lower RMDs).

Aggregation Rules
| Account Type | Can You Aggregate? | Meaning |
|---|---|---|
| Traditional IRAs | Yes | Calculate each IRA’s RMD separately, but take the total from any one IRA |
| 401(k) plans | No | Must take each 401(k)’s RMD from that specific 401(k) |
| 403(b) plans | Yes | Can aggregate like IRAs |
| Mix of IRA + 401(k) | No | IRA RMDs and 401(k) RMDs are separate calculations |
Why aggregation matters: If you have three Traditional IRAs worth $200K, $300K, and $500K, you calculate each one’s RMD separately, then take the total ($37,736 on $1M) from whichever IRA you choose. This lets you strategically draw down the least-performing account.
RMD Strategies to Reduce Taxes
1. Roth Conversions Before Age 73
The most powerful RMD strategy: convert Traditional IRA money to Roth in the years between retirement and age 73, when your income (and tax bracket) may be unusually low.
| Strategy | How It Works | Tax Savings |
|---|---|---|
| Fill up low brackets | Convert just enough to stay in the 12% or 22% bracket | Pay 12-22% now vs 24%+ later |
| IRMAA-aware conversions | Keep MAGI below Medicare premium thresholds | Avoid $1,000-$5,000/yr surcharges |
| Multi-year ladder | Convert $50K-$100K/year over 5-10 years | Spreads tax impact evenly |
Example: A retiree with $50,000 Social Security income could convert ~$45,000/year from Traditional to Roth while staying in the 22% bracket. Over 8 years (ages 65-72), that moves $360,000 out of RMD-subject accounts.
2. Qualified Charitable Distributions (QCDs)
If you donate to charity, a QCD is the most tax-efficient way to do it after age 70½:
| Feature | QCD | Regular Charitable Donation |
|---|---|---|
| Maximum (2026) | $105,000/year | No limit |
| Counts as RMD? | Yes | No |
| Taxable income? | No | Yes (but you get a deduction) |
| Must itemize? | No | Yes (to get deduction) |
| Reduces MAGI? | Yes | Maybe (if you itemize) |
The QCD advantage is significant. Most retirees take the standard deduction, which means regular charitable donations provide no tax benefit. But a QCD is excluded from income entirely — it’s the equivalent of a tax deduction even if you don’t itemize.
3. Still-Working Exception
If you’re still employed past 73 and don’t own more than 5% of the company, you can delay RMDs from your current employer’s 401(k) until you actually retire. This doesn’t apply to IRAs or old 401(k)s from previous employers.
4. Strategic Withdrawal Timing
| Month | Strategy | Why |
|---|---|---|
| January | Take RMD early | If you expect a high-income year, get it done |
| December | Take RMD late | Maximize tax-deferred growth; know your full-year income |
| Monthly | Spread across 12 months | Acts like a paycheck; avoids lumpy income |
See RMD Strategies for advanced approaches including the “bracket-filling” technique.
What Happens If You Miss an RMD
| Scenario | Penalty | Recovery Action |
|---|---|---|
| Missed entirely | 25% of missed amount | Take the distribution ASAP; file Form 5329 |
| Corrected within 2 years | Reduced to 10% | File amended 5329 showing correction |
| Reasonable cause | Potentially $0 | Write IRS letter explaining circumstances; request waiver |
| Took too little | 25% on the shortfall | Take the remaining amount; file 5329 |
The IRS is forgiving for honest mistakes. If you forgot or miscalculated, take the distribution immediately, file Form 5329 with an explanation, and request a waiver. The IRS routinely waives penalties when there’s a clear good-faith effort to comply.

RMDs and Your Tax Bracket
RMDs are taxed as ordinary income, stacking on top of your other income:
| Other Income | RMD Amount | Total Income | Federal Tax Rate on RMD |
|---|---|---|---|
| $30,000 (SS only) | $20,000 | $50,000 | 12% |
| $50,000 (SS + pension) | $30,000 | $80,000 | 22% |
| $75,000 (multiple sources) | $40,000 | $115,000 | 24% |
| $100,000+ | $50,000 | $150,000+ | 24-32% |
The IRMAA trap: Medicare premiums increase at specific income thresholds ($103,000 single / $206,000 married in 2026). A large RMD can push you over a threshold, adding $1,000-$5,000 in annual Medicare surcharges. Plan RMDs with IRMAA brackets in mind.
RMDs for Inherited Accounts
The rules changed significantly under the SECURE Act (2020) and SECURE 2.0 (2023):
| Beneficiary Type | Distribution Rule | Deadline |
|---|---|---|
| Surviving spouse | Can treat as own; use own RMD schedule | Own RMD age |
| Non-spouse (10+ years younger) | 10-year rule — must empty account within 10 years | Dec 31 of 10th year |
| Eligible designated beneficiary | Can stretch over life expectancy | Annual RMDs based on age |
| Non-person (estate, charity) | 5-year rule | Empty within 5 years |
2025 IRS clarification: Non-spouse beneficiaries who inherited from someone already taking RMDs must take annual RMDs during the 10-year window AND empty the account by year 10. This was a contentious rule that the IRS delayed enforcing until 2025.
How RMDs Interact With Social Security Taxes
RMDs stack on top of other income, which can make more of your Social Security benefits taxable — a double tax hit many retirees don’t anticipate:
| Combined Income (Single) | Social Security % Taxable | Tax Impact of Adding $30K RMD |
|---|---|---|
| Under $25,000 | 0% | May push SS into taxable range |
| $25,000-$34,000 | Up to 50% | Additional $2,000-$4,000 in tax |
| Over $34,000 | Up to 85% | Full 85% of SS is taxable |
“Combined income” is your AGI plus nontaxable interest plus half your Social Security benefits. RMDs count dollar-for-dollar toward AGI, which means a $30,000 RMD can trigger $25,500 of Social Security benefits becoming taxable (85% × $30,000) — effectively increasing your taxable income by $55,500, not just $30,000.
This cascade effect is why pre-73 Roth conversions are so valuable. Every dollar you convert to Roth before RMDs begin is a dollar that won’t trigger additional Social Security taxation later. A retiree with $800,000 in Traditional accounts who converts $300,000 to Roth between ages 65-72 could save $50,000-$100,000 in lifetime taxes through reduced RMDs and lower Social Security taxation.
The Optimal Withdrawal Order in Retirement
| Order | Source | Why |
|---|---|---|
| 1 | RMDs (required) | Must take these first — penalties otherwise |
| 2 | Taxable brokerage | Long-term gains taxed at 0-20% |
| 3 | Traditional IRA/401(k) | Fill up your current tax bracket |
| 4 | Roth IRA | Save for last — grows tax-free forever |

The Bottom Line
RMDs are inevitable for Traditional retirement accounts, but the tax impact is manageable with planning. The best strategy starts years before age 73: convert Traditional money to Roth during low-income years to reduce future RMDs, use QCDs if you’re charitably inclined, and time your withdrawals to stay below Medicare premium thresholds. If you miss an RMD, don’t panic — correct it quickly, file Form 5329, and the penalty is usually waived or reduced. The worst RMD mistake isn’t missing one — it’s failing to do Roth conversions in the decade before they start.
