Which account you draw from first can matter as much as how much you draw — plus the Medicare surcharge most people never see coming.
Once buckets are labeled, the next conversation usually goes:
“So we just take from the taxable account first, right? That’s what we read.”
Sometimes that’s reasonable. Sometimes it’s how people create a tax cliff later when deferred accounts explode into RMDs. “Always do X” fails because households don’t share the same gap, the same IRMAA proximity, the same charity goals, or the same birth-year RMD age.
This chapter teaches concepts and look-up habits, not gospel brackets.
Withdrawal order = which bucket you draw from, in which years, to fund the stack’s gap — while managing tax brackets, Medicare IRMAA exposure, Social Security taxation interactions, and eventually required minimum distributions.
RMDs are the disruptor: the IRS forces a withdrawal pattern from deferred accounts whether your gap needed it or not.
A “smart” order in your 60s can become a trap in your RMD years if you never touched deferred balances and never built Roth room. Conversely, draining Roth early to “save taxes” can remove flexibility you needed for a high-medical year. Order is strategy across decades, not a one-year hack.
Common sequencing ideas (teaching tools, not commandments)
You’ll hear versions of these:
1. Spend taxable first, then deferred, then Roth. Preserves tax-advantaged
growth longer; can make sense for some early-retirement bridges. Risk: deferred pile grows into a larger RMD / IRMAA problem. 2. Blend withdrawals across taxable and deferred to “fill” a tax bracket without
leaping into the next. Requires annual tax projection habits. 3. Use Roth for shock years — high medical, big one-time expense — when you
don’t want extra taxable income. 4. Coordinate with Social Security timing so you’re not stacking large deferred
withdrawals on top of a new benefit in a clumsy year.
Each idea has a “where this doesn’t help.” Charitable give strategies, QCDs (qualified charitable distributions) from IRAs after eligible ages, and basis recovery rules can change the math — ask a tax pro before you act on a blog mnemonic.
Why “always do X” fails
Two spouses with different ages → different Medicare IRMAA clocks and RMD ages. A large capital gain from selling a business or home (partial exclusions possible — LOOK UP) can crowd a year. Moving to a different state changes state tax on retirement income. A widow(er) may face a bracket cliff when filing status changes. Healthcare premiums and IRMAA are income-sensitive; a withdrawal that looks fine for federal tax can still hurt Medicare costs two years later.
The scene I see most: a couple “does taxable first” for eight clean years, feels brilliant, then the first RMD year arrives and ordinary income jumps whether the gap needed it or not. IRMAA notice shows up on a lag. They didn’t do anything immoral. They followed a slogan that ignored the disruptor.
Second scene: someone drains Roth early because a friend said “tax-free forever means use it.” Then a high-medical year hits and every extra dollar of deferred income pushes brackets and premiums. Roth was the shock absorber they already spent.
If your plan can’t explain why this year differs, it’s a slogan.
LOOK UP CURRENT — Annual refresh rule (required habit) Tax brackets, standard deduction, IRMAA brackets, RMD ages/percentages, contribution limits, and capital-gains thresholds change. Before acting: look up current IRS / SSA / Medicare (CMS) figures for the tax year you’re planning — then re-run the sequence. Appendix homes: Table Tax (brackets / standard deduction), Table IRMAA, Table RMD, Table Limits, Table HSA. Those tables are EXAMPLE refreshers, not eternal law. Do not tattoo last year’s table into a binder and call it a plan.
The RMD disruptor
Required minimum distributions force money out of most tax-deferred retirement accounts starting at an age that depends on your birth cohort under SECURE-era law.
Pattern to teach (confirm every time on IRS.gov — see Appendix Table RMD):
Many people born 1951–1959 → RMDs generally begin at age 73. Many people born 1960 or later → age 75. Those cohort ages are a SECURE-era teaching pattern, not a tattoo. 1959 has had statutory ambiguity in IRS guidance — verify current before you plan.
First RMD timing can allow delay until April 1 of the following year — which can dump two RMDs into one tax year if you also take the next one on schedule. Still- working exceptions may delay RMDs from some employer plans (often not for 5% owners). IRAs generally don’t get the still-working pass. Surviving-spouse rules have their own complexity post-SECURE.
RMDs are calculated using IRS life-expectancy tables and your prior year-end balance. Percentages aren’t a vibe — LOOK UP CURRENT for the year you must take.
Still-working exception — read the fine print. Some employer defined-contribution plans allow non–5% owners who are still working for that employer to delay RMDs from that plan until retirement. IRAs generally do not get this pass. Owning more
than 5% of the business usually blocks the delay. “I’m still consulting a little” is not the same as the plan’s definition of employed. Ask the plan administrator in writing before you assume the exception applies.
QCDs as a partial pressure valve (concept only). After you reach the eligible age under current law, a qualified charitable distribution from an IRA can sometimes satisfy charitable intent and RMD pressure in the same move — rules, dollar caps, and timing are LOOK UP / tax-pro territory. This is not a pitch to give money away. It is a named tool so you ask the right question instead of inventing one.
LOOK UP CURRENT — RMD details IRS Retirement Topics: Required Minimum Distributions. Confirm applicable age for your birth year, Uniform Lifetime Table percentage, deadlines, still-working exception eligibility, QCD rules if charity is in play, and beneficiary RMD rules if relevant. Refresh when laws or tables update.
IRMAA as a stealth withdrawal tax
IRMAA adds to Medicare Part B and Part D premiums when MAGI crosses tiers — typically based on a lookback (often two years). A big deferred withdrawal, conversion, or capital gain can raise premiums later even if you “needed” the money. Life-changing events may allow SSA-44 reconsideration in some cases — ask SSA; don’t assume.
Split IRMAA planning from Social Security earnings-test planning. Same household return, different levers.
EXAMPLE — IRMAA pattern (CMS annual tables) CMS publishes IRMAA income tiers and premium add-ons each year (e.g., base tier thresholds for single/joint filers based on MAGI from a prior year). Source pattern: CMS Medicare Parts A & B premiums/deductibles fact sheet (includes IRMAA). Any dollar tier you write in a worksheet is EXAMPLE for that calendar year — LOOK UP CURRENT before relying on it.
A practical annual rhythm
withdrawals, conversions). 3. LOOK UP CURRENT brackets, IRMAA tiers, and RMD requirements. 4. Choose a withdrawal mix for this year with a tax pro or tax-aware advisor. 5. Revisit after major events: job exit, spouse death, home sale, big medical year.
Calendar cues that beat vibes: January = refresh IRS/CMS tables and write the year’s withdrawal paragraph. April = note what the return actually showed vs. what you projected. October–November = IRMAA and Medicare planning awareness for the next premium year; don’t wait for the SSA letter to be your first clue. Birthdays that hit RMD cohort age = treat the prior December 31 balance as a planning input, not a surprise.
Bracket “fill” without making it gospel
You’ll hear “fill the 22% bracket” or “fill the 24%.” As a conversation starter with a tax pro, filling unused room in a lower bracket with deferred withdrawals or conversions can be rational. As a commandment tattooed on a napkin, it fails when:
IRMAA tiers don’t align with federal bracket hinges. State tax stacks on top. A capital gain or pension start already filled the room. Paying the tax would raid reserves you need for healthcare.
Use “is there room?” as a question. Do not use last year’s hinge dollars as this year’s religion.
Write a one-paragraph policy your spouse could follow: “In normal years we fund the gap from ___ and . In high-medical years we prefer . We will not ignore deferred accounts entirely before RMD age. We refresh IRS/CMS numbers every January.”
That paragraph beats a complicated spreadsheet you don’t open.
This chapter will not give you a permanent order that works for all ages and all states. It will not replace TurboTax or a CPA. QCD eligibility ages, Roth ordering rules, and Net Unrealized Appreciation on employer stock need specialist eyes. If someone sells you a product as the solution to RMDs without modeling IRMAA and your gap, you’re in a pitch.
Contrast — gospel brackets vs. look-up culture
Year-locked tax gospel (“always fill the 22% bracket”) rots when Congress moves brackets or your IRMAA cliff sits in an awkward place. Look-up culture treats tables as fresh groceries: buy them for the year you’re cooking. Popular finance sometimes says “taxes will be higher later” or “lower later” as prophecy. Broker/educator view: build optionality across buckets so either prophecy is survivable.
an earlier chapter checklist
I have a bucket inventory before debating order. I know my RMD cohort age (73 vs 75) — confirmed on IRS.gov. I understand first-RMD timing can stack two RMDs in one calendar year. I LOOK UP CURRENT tax brackets, IRMAA tiers, and RMD % before acting each year. I wrote a one-paragraph withdrawal policy a spouse could follow. I did not adopt an “always taxable first” slogan without checking future RMD/IRMAA risk. Major life events trigger a re-run, not autopilot.
Soft close
Worth a January look-up ritual and a one-paragraph policy — even if this year’s withdrawal mix stays the same. Stay-put is fine. Calendar amnesia is expensive.
