The Withdrawal Order That Can Cost You Six Figures

The Question Most People Can't Answer

Say you retire at 65 with three accounts: a traditional IRA with $800,000, a Roth IRA with $200,000, and a taxable brokerage account with $150,000. You need $60,000 a year beyond your guaranteed income. Which account do you draw from first?

Most people answer with something like "whatever makes sense" or "my advisor handles that." A few have heard of Roth-last rules and try to apply them loosely. Almost nobody has a written, sequenced withdrawal strategy that accounts for tax bracket, the RMD timeline, Social Security inclusion thresholds, and legacy goals simultaneously, across every year of retirement.

That missing sequence costs real money. People who never knew the order mattered have paid six figures in additional tax over a 20-year retirement because of it.

The Conventional Rule — and Where It Breaks

The standard withdrawal framework says: draw from taxable accounts first, then traditional pre-tax accounts, then Roth last. The logic holds up on its own terms. Taxable accounts generate ongoing tax events as they grow — capital gains, dividends — so depleting them first removes that drag. Traditional IRA and 401(k) money is pre-tax, so you owe ordinary income tax when you take it out, and you want to delay that as long as possible. Roth money is tax-free and compounds without tax drag, so you preserve it the longest.

That framework isn't wrong. But applied mechanically, without looking at your specific tax situation, it can actually increase your lifetime tax bill.

The years between retirement and age 73 are often your lowest-income years. Social Security may not have started yet, and earned income is gone. If you follow the conventional rule and pull from taxable accounts first, you're sitting in the 12% or 22% bracket while your traditional IRA compounds, untouched. Every dollar in that IRA that isn't converted or withdrawn during that low-bracket window will eventually come out as a required minimum distribution (RMD), in a higher bracket, in a year when Social Security is also fully taxable — potentially triggering Medicare IRMAA surcharges on top of it.

Filling the Bracket, Year by Year

The more precise approach isn't a fixed rule. Every year in retirement, look at your projected income from all sources — guaranteed income, Social Security, capital gains, dividends — and ask: how much space is left in my current tax bracket? Then ask what the most tax-efficient source is to fill that space.

Sometimes that means a Roth conversion. Sometimes it means an intentional IRA withdrawal before you're forced to take one. Sometimes it means harvesting capital gains in a year your bracket allows it. The sequence is responsive, not static — it changes every year based on your actual numbers.

Why This Gets Missed

If sequencing is this consequential, why doesn't every retirement plan include it? Two reasons.

The first is structural. The financial planning industry is largely organized around asset management — building portfolios, managing allocations, rebalancing — and the business model centers on assets under management. That model is excellent for accumulation. It has almost no infrastructure for managing the tax sequence of withdrawals in distribution. Quarterly statements and performance reports don't show a year-by-year tax bracket projection, and they don't flag when a conversion window is closing.

The second is complexity. Year-by-year bracket management across a 25-year retirement requires modeling Social Security inclusion formulas, IRMAA thresholds, capital gains rates, RMD projections, and Roth conversion math simultaneously, updated every year. That's ongoing work, not a one-time analysis. Most people don't know to ask for it because they don't know it exists.

A couple can retire at 65 with $1.2 million in an IRA, get a solid portfolio and a 4% withdrawal rate, and genuinely be told they're on track — and that may be true. But if nobody runs the bracket projection for the years between 65 and 73, and nobody models how much of that IRA can be converted at 12% or 22% before forced distributions start, the "on track" assessment is missing one of the most expensive line items in their retirement.

The accumulation expert manages your portfolio. The income engineer manages your tax bracket. Most investors don't realize those are two different jobs — or that the second one often has the larger lifetime impact.

Richard and Carol: Same Assets, Different Sequence

Richard and Carol are both 66, with nearly identical assets: a $900,000 traditional IRA, a $150,000 Roth, a $200,000 taxable brokerage account, $32,000 a year in Social Security, and $84,000 a year in expenses — a $52,000 annual gap to fill from savings.

Richard follows the conventional rule: taxable account first, roughly $50,000 a year for about three years until it's gone, then the IRA. His untouched IRA grows past $1 million by age 69. His first RMD at 73 is approximately $45,000. Combined with Social Security, that puts him firmly in the 22% bracket, with Medicare IRMAA surcharges triggering higher Part B premiums. His Roth, never touched, sits at $250,000.

Carol's advisor runs a bracket-filling analysis every January. In year one, she draws $20,000 from her taxable account and converts $40,000 from IRA to Roth, staying inside the 22% bracket without crossing into 24% — paying tax now, at a rate she controls, on income she chose. She repeats a version of this through age 72, converting between $30,000 and $50,000 a year depending on Social Security phase-in and capital gains in her taxable account.

By 73, Carol's traditional IRA sits at $580,000 instead of over $1 million. Her first RMD is $22,000 instead of $45,000. She stays in the 12% bracket and avoids IRMAA entirely. Her Roth, now $400,000, keeps compounding tax-free.

Same starting assets, same income need. Approximately $230,000 less in federal income tax over a 20-year retirement — not from a different investment selection, but from sequence, managed every year instead of set once and left alone.

A Four-Step Way to Build a Sequence

This isn't a concept to understand once. It's something to implement and revisit.

• Get a year-by-year bracket projection before you retire. What does income look like at 65, 68, 70, and 73? Where does Social Security start? Where do RMDs kick in, and at what size? That projection shows how much space is available in each year's bracket and how much IRA money can move at favorable rates.
• Build a conversion plan for the pre-RMD window. If you have a traditional IRA balance of $500,000 or more and you're between 60 and 72, every year without a conversion plan is a year of that window going unused. The window doesn't announce itself — it closes quietly at 73.
• Revisit the projection every year. Social Security cost-of-living adjustments, market returns, and actual spending all shift the bracket picture. The right conversion amount at 67 may be wrong at 69.
• Coordinate with a tax advisor. Sequencing lives at the intersection of income architecture and tax planning. The income side and the execution side need to work together, not separately.

Answering the Common Objections

"My accountant already handles my taxes." An accountant handles what already happened — filing accurately based on the year that just closed. Income sequencing is forward-looking: which accounts to draw from, when to convert, how to manage the bracket for the next three to five years. Very few accountants run a ten-year Roth conversion model looking forward. Both conversations matter. They're not the same conversation.

"Why pay taxes now instead of later?" Because earlier doesn't always mean more. If you're in the 12% bracket now and projected to land in the 24% or 32% bracket once RMDs hit, converting now means paying less, not more. The real question isn't timing — it's rate. What rate will you pay, and do you have the ability to choose a lower one now?

"It's all in a 401(k), not an IRA — does this apply to me?" Yes. At retirement or separation from service, most 401(k) balances can be rolled into a traditional IRA, which unlocks the flexibility needed for Roth conversions, withdrawals, and sequencing that a 401(k) structure typically doesn't offer directly.
