A clear, step-by-step guide to choosing the right withdrawal order from taxable, traditional, and Roth accounts while managing RMDs, Medicare IRMAA, and capi...
If you have money in a traditional IRA or an old 401(k), the IRS eventually wants its turn. That is what Required Minimum Distributions, or RMDs, are all about. And if you miss one, the penalties can be painfully expensive.
The good news: RMDs are very manageable once you know the rules and build a simple annual routine. Let’s walk through what counts, when you must start, how the math works, and the practical strategies I’ve seen work best for real people. Rules do change, and a few details depend on your account type, employer plan, and birth year, so confirm your specifics if anything looks unusual.
What an RMD is
An RMD is the minimum amount you must withdraw each year from certain tax-deferred retirement accounts once you reach a specific age. It exists because:
- You got a tax break earlier (deductions and tax-deferred growth).
- The IRS requires distributions later so those dollars eventually get taxed.
Think of tax-deferred accounts like an “income tax tab” you were allowed to run for years. RMDs are the IRS saying, “It’s time to start closing out that tab and paying the tax as you withdraw.”
Accounts with RMDs
Accounts that typically have RMDs
- Traditional IRAs
- Rollover IRAs
- SEP IRAs
- SIMPLE IRAs
- Most employer plans: 401(k), 403(b), and similar plans, including governmental 457(b) plans
Accounts that typically do not have RMDs during your lifetime
- Roth IRAs (no lifetime RMDs for the original owner)
Key exceptions
- Roth 401(k) and Roth 403(b): As of 2024 (a SECURE 2.0 change), these generally no longer have lifetime RMDs for the original account owner. If you have an older plan document or unusual plan rules, confirm with your plan provider, but most people will not owe RMDs on the Roth side anymore.
- Still working? Some employer plans let you delay RMDs from that specific plan if you are still working there. This “still working” exception is plan-specific and does not apply to IRAs.
If you have multiple old accounts scattered around, this is where people get tripped up. A clean list of accounts and account types goes a long way.
When RMDs start
RMD rules have changed in recent years, so it is smart to confirm your specific “RMD age.” Here is the plain-English summary most people are looking for:
- Age 73: For many retirees today, your RMD age is 73.
- Age 75: Under SECURE 2.0, the RMD age is scheduled to increase to 75 for people who reach age 74 after 2032.
Because the exact start age depends on your birth year (and the calendar year you reach the triggering age), do a quick double-check with your custodian, a CFP professional, or a tax pro if you are near the line.
First-year deadline
Your first RMD can be taken in the year you reach your RMD age, but you typically have the option to delay it until April 1 of the following year. That April 1 date is often called your required beginning date, meaning the latest date your first RMD must be taken.
Kitchen table warning: If you delay your first RMD until next year, you may have to take two taxable distributions in that next year (the delayed first-year RMD plus your normal second-year RMD by year-end). That can push you into a higher tax bracket, increase Medicare premiums, and make more of your Social Security taxable.
Ongoing deadline
After your first RMD year, RMDs are generally due by December 31 each year.
Practical tip: If you are not sure whether delaying makes sense, the decision usually comes down to taxes. A CFP or tax pro can run a quick comparison.
How RMDs are calculated
Most RMDs follow a straightforward formula:
- RMD = prior year end account balance (usually December 31) divided by a life expectancy factor from an IRS table.
Custodians often calculate your RMD for you, especially for IRAs. But I still like retirees to understand the “why,” because:
- You might have multiple accounts at different firms.
- You might need to coordinate withdrawals with taxes.
- Mistakes happen, and the IRS penalty is not a small slap on the wrist.
Example
Let’s say your traditional IRA balance on December 31 last year was $500,000. If your IRS life expectancy factor for this year is 25.6, your RMD would be:
- $500,000 ÷ 25.6 = $19,531 (approximately)
That distribution is generally taxed as ordinary income unless you have nondeductible basis tracked on IRS Form 8606.
Note: Special situations can change the math, including inherited accounts and certain spouse age differences. When in doubt, ask before you withdraw.
Multiple accounts
This is one of the most common “I didn’t know that” moments.
Traditional IRAs: you can aggregate
If you have multiple traditional IRAs, you generally can:
- Calculate the RMD for each IRA,
- Add them up, then
- Withdraw the total from one IRA (or split it across several).
Employer plans: usually no aggregating
For most employer plans, you generally must take the RMD from each plan that requires one. You cannot usually take one big distribution from your IRA and count it as your 401(k) RMD.
Real-life simplifier: Many retirees consolidate old employer plans into a traditional IRA before RMD age. That can make the rules easier, but always check for reasons not to roll over (strong institutional funds, creditor protection considerations, or if you are doing a “still working” delay).
Missing an RMD
The IRS penalty for failing to take an RMD has historically been severe. SECURE 2.0 reduced the penalty in many situations, but it can still be costly. Penalty rates and cure rules are the kind of thing Congress tweaks, so confirm current numbers for your tax year if you are dealing with a miss.
- In general, the penalty is a percentage of the amount you failed to withdraw.
- It can be lower if you correct the mistake promptly and file the right paperwork.
If you realize you missed an RMD, do not panic. Do this instead:
- Take the missed distribution as soon as possible.
- Document what happened (custodian error, misunderstanding, illness, etc.).
- Talk with a tax pro about requesting penalty relief if appropriate. The IRS can waive penalties in certain reasonable situations, but paperwork and timing matter.
Best prevention: automate it. A yearly “December scramble” is where mistakes happen.
Tax-smart strategies
RMDs are not just a compliance chore. They are a planning opportunity. Here are strategies I regularly discuss with retirees and late-starters. Use them as ideas to explore, not one-size-fits-all instructions.
1) Build an “RMD paycheck” schedule
Instead of taking one large withdrawal late in the year, consider monthly or quarterly distributions. Benefits include:
- Smoother cash flow
- Less temptation to overspend the lump sum
- More consistent tax withholding
2) Use withholding to avoid tax surprises
You can often choose federal and state withholding from your IRA distribution. Many retirees use RMD withholding as a simple way to cover their tax bill, rather than making quarterly estimated payments.
3) Consider Qualified Charitable Distributions (QCDs)
If you are charitably inclined and you are eligible, a QCD can be one of the cleanest ways to reduce the tax sting of RMDs.
QCD quick rules
- Age rule: You are generally eligible starting at age 70½.
- Account rule: QCDs are made from IRAs (not typically directly from a 401(k) or 403(b)).
- Payee rule: The money must go directly to a qualified charity.
- Annual limit: There is an annual dollar cap, and limits can change over time.
Done correctly, QCDs can count toward your RMD and keep taxable income lower, which may help with Medicare premium brackets and Social Security taxation. Done sloppily, they can become a paperwork headache.
4) Look at Roth conversions before RMD age
A Roth conversion is basically paying taxes on purpose today to reduce taxes later. Converting some traditional IRA dollars to a Roth IRA before RMDs begin can:
- Reduce future RMDs
- Potentially lower lifetime taxes
- Create more flexible, tax-free income later
This is not a one-size-fits-all move. The “right” amount to convert often depends on your current tax bracket, future income, and goals for heirs.
5) Coordinate RMDs with Social Security and Medicare
RMDs can increase your adjusted gross income, which can:
- Cause more of your Social Security benefits to be taxable
- Increase Medicare Part B and Part D premiums through income-related surcharges
Even if you cannot avoid RMDs, you can often plan around them by smoothing income, timing conversions, or using QCDs.
After you take an RMD
An RMD is a required withdrawal, not a required spending spree.
- Need the cash for living expenses? Great. Use it to fund your budget and consider setting up automatic transfers.
- Do not need it right now? You can usually invest it in a taxable brokerage account, buy bonds or CDs, or keep it in a high-yield savings account, depending on your goals and risk tolerance.
- Still working? You cannot put the RMD back into an IRA, but you may be able to increase workplace plan contributions to keep saving if you have earned income.
The key is to make the RMD fit your broader income plan, not the other way around.
Inherited accounts
Inherited retirement accounts are a separate rulebook, and they are a common source of expensive misunderstandings. A few high-level points:
- Inherited IRAs and inherited employer plans can have different timing rules than accounts you own yourself.
- Many non-spouse beneficiaries are subject to a 10-year payout rule, but the details depend on when the original owner died and the beneficiary category.
- Spouses often have additional options that can change required distributions.
If you inherited an account, it is worth getting clear guidance early. The cost of guessing wrong can be high.
RMD checklist
- January to February: Confirm which accounts have RMDs this year, confirm your RMD age and deadlines, and verify beneficiaries are updated.
- March to April: Decide whether you want monthly, quarterly, or annual withdrawals. Set tax withholding.
- Mid-year: Recheck totals if you consolidated accounts, moved custodians, or inherited an account.
- October to November: If you are doing QCDs, get the paperwork moving early.
- December: Confirm your RMD is fully satisfied before the year-end deadline.
If you like one-and-done simplicity, set automatic distributions and then verify them each fall. It is boring, which is exactly what we want for something with IRS penalties attached.
Common questions
Do RMDs apply to Roth IRAs?
Not during your lifetime as the original owner. Beneficiaries have their own inherited account rules.
Can my custodian calculate my RMD for me?
Often, yes, especially for IRAs. Still, you are responsible for getting the correct amount out by the deadline, particularly if you have multiple accounts.
If my account drops in value, does my RMD drop too?
Your RMD is based on your prior year-end balance. If markets drop after that, the RMD amount does not automatically adjust mid-year.
Can I take more than my RMD?
Yes. You can always withdraw more. But extra withdrawals are typically taxable and they do not “prepay” next year’s RMD in most cases.
Do RMDs affect my tax bracket?
They can. RMDs add to taxable income, which can push you into a higher bracket or trigger Medicare income surcharges. That is why planning the timing, withholding, and possible Roth conversions matters.
When to get help
If any of these apply, it is smart to get a CFP professional or tax pro involved:
- You have multiple retirement accounts across different custodians.
- You are considering Roth conversions.
- You give to charity and want to use QCDs correctly.
- You are worried about Medicare premiums or Social Security taxation.
- You inherited a retirement account and are unsure of the distribution rules.
RMDs are one of those areas where one good planning meeting can prevent years of unnecessary taxes and headaches.
The bottom line
RMDs are not a trap, but they do require a plan. Once you know (1) which accounts are affected, (2) your start date and deadlines, and (3) how to coordinate withdrawals with taxes, the whole thing becomes routine.
If you want a simple next step, start here: make a list of every retirement account you and your spouse have, note the account type, and confirm whether you have already set up automatic distributions. That one hour of organization is often the difference between “I hope I did this right” and “I know I’m on track.”
