E106: Why Most Retirees Build The Portfolio Before The Plan

Why Your Income Plan Has to Come Before Your Portfolio Mix

Picking a stock and bond mix based on your age and calling it a retirement plan skips the step that protects you once paychecks stop, building an income plan first. For a CRNA or nurse practitioner without a steady pension to lean on, skipping that step causes more stress than almost anything else I see.

Retirement runs on income, not on investment performance, even though investments are part of how that income gets funded. Once paychecks stop or slow down, the questions shift from how much an account can grow to how much money is needed this year, where it comes from, and what pulling it from that account costs in taxes. Standard retirement advice usually stays focused on the portfolio, things like rebalance annually, shift toward bonds as you age, watch your expense ratios. Those are reasonable practices, but they skip the questions that keep retirees up at night, whether to claim Social Security now or wait, which account to pull from first, and whether they’ll owe more in taxes than expected once RMDs begin.

This is especially true for CRNAs and NPs, since retirement rarely follows a single clean script of one employer, one account, and one last day of work. Some wind down gradually, dropping to part-time or picking up occasional PRN shifts well into what would otherwise look like retirement. For these households, retirement income often blends Social Security, a portfolio built from more than one account type, and sometimes a variable stream of clinical income that’s being actively chosen rather than a fixed paycheck. Planning around this reality takes more than an age-based formula, and it carries an emotional weight that doesn’t show up on a spreadsheet.

Managing your own money in retirement is emotional, maybe more emotional than any other stage of your financial life, because for the first time ever, there’s no paycheck coming in to correct a mistake. That’s part of why a generic allocation feels like the safer choice. Copying a formula is easier than sitting down and admitting the number isn’t known yet. This discomfort is why the income plan needs to come first. Once the real number is known, a lot of that anxiety has somewhere to go.

The cookie-cutter version plays out predictably. Somebody retires, gets placed into a conservative mix based on age, and withdrawals get pulled more or less randomly from whichever account is easiest to touch. Social Security gets claimed whenever feels natural, usually as early as possible. Nobody writes down what the household needs to spend each year, so nobody can say with confidence whether the investment plan covers it. That approach can survive for a retiree with a pension or one predictable Social Security check, mostly by luck, since the income side of the equation is simple enough that a rough guess tends to land close. It holds up less well for a CRNA or nurse practitioner carrying a solo 401(k) built from a decade of side work, a hospital 403(b), maybe an old IRA rolled over from an earlier job, and no pension at all. More accounts mean more decisions about order and timing, and a random approach to withdrawals produces random tax bills.

The income-first approach starts by separating spending into two categories, essential and flexible, the same way you would at any stage of life, except now there’s no paycheck refilling the checking account automatically. Essential spending covers housing, health insurance, Medicare premiums, anything contractually required. Flexible spending covers things like travel and gifts to family, the kind of costs that can flex up in a good month and down in a lean one. Income sources then line up against the essential number specifically, Social Security first, then a pension if there is one. A lot of CRNAs and NPs don’t have one, so whatever’s left becomes the portfolio’s job to cover. Any ongoing PRN or per diem income counts too, though differently, since it’s optional and can stop whenever that decision is made.

The goal is simple to say and harder to do, covering essential spending with income that’s reliable, Social Security, a pension if there is one, maybe a slice of the portfolio parked in something stable, then let flexible spending ride on whatever’s left, including the part of the portfolio that stays invested for growth. Once that split is known, the bond allocation stops being a guess based on a birthday and becomes a number tied to a specific spending gap. If Social Security alone nearly covers essentials, not much needs to sit in bonds. If there’s a noticeable gap between essential spending and guaranteed income, the gap, not age, determines how much needs to sit in something stable. Asset location follows the same logic. Money needed soon belongs somewhere accessible and predictable, while money that won’t be touched for a decade or more can stay invested for growth. Where it’s held, in a tax-deferred account or a taxable one, depends on how it will eventually be taxed on the way out.

Social Security works best as an income decision made on purpose. Full retirement age currently sits at 67 under current rules. Claim as early as 62, and the monthly benefit is permanently reduced. Wait past full retirement age up to 70, and it keeps growing. How long to wait comes down to the size of the essential spending gap, and how much of it needs covering right away versus how much the portfolio can carry in the meantime. That’s the trade-off, and there’s no version of it that looks the same for everyone.

The account mix is where this gets specific for CRNAs and nurse practitioners. It’s common to carry more than one retirement account built from more than one kind of income over the years, a 403(b) or 401(k) from hospital W-2 work alongside a solo 401(k) built from years of 1099 or locum income on the side. In retirement, this turns into a withdrawal sequencing question, which account to pull from first, which one to leave alone longest, and when required minimum distributions (RMDs) start forcing the issue. Under current rules, RMDs on pre-tax deferred accounts start at age 73 for people born between 1951 and 1959, and age 75 for anyone born in 1960 or later. For someone retiring in their early 60s, that can leave a decade or more of control over exactly how much taxable income shows up on a tax return each year, before required distributions take that choice away. This window is where withdrawal order carries the most weight. Pulling from taxable accounts first, or making modest conversions from tax-deferred accounts into Roth accounts during those lower-income years, can change the tax picture substantially by the time RMDs begin at 73 or 75.

There’s also a cost that tends to surprise people only once it shows up as a bill. Anyone who’s done 1099 or locum work should know that most malpractice policies are claims-made, covering only claims filed while the policy is active. Stepping away from clinical work for good, closing that chapter rather than switching jobs, is what triggers what’s sometimes called a true tail, a lump sum payment covering claims that could still surface after practicing has ended entirely. That differs from the tail coverage paid when leaving one job for another with new coverage already lined up on the next contract. A true tail is priced to cover the gap indefinitely, since there’s no next job to hand the risk to, which is part of why it tends to run larger than a routine job-to-job tail. It’s a one-time, often sizable expense that lands right at the transition into retirement, deserving a planned-for place in the budget instead of a surprise on the bank statement.

The withdrawal order, Social Security timing, tail coverage bill, and bond allocation only get sized correctly once the income plan is built first. Investments are the vehicle. The income plan is the map. Unlike the accumulation years, where a bond allocation mistake mostly costs some growth over a long horizon, a mistake in the income plan during retirement shows up faster. It shows up either as an unexpected spending cut or a tax bill that better sequencing could have avoided.

A hypothetical example shows how these pieces come together for a 62-year-old CRNA who just wound down her clinical work for good, closing out the last of her PRN shifts. Over her career she built a 403(b) through hospital jobs and a solo 401(k) from years of weekend and locum work on the side. Her essential spending, including housing and Medicare supplement premiums until Medicare eligibility, runs around $5,500 a month, or roughly $66,000 a year. She also owes a true tail malpractice payment this year for closing out her practice, a one-time cost in the low five figures depending on her coverage limits and carrier, and that bill counts as essential spending for this transition year because it isn’t optional.

At full retirement age of 67, her projected Social Security benefit would cover a solid portion of the essential number, though not all of it, and she’s five years away from full retirement age right now. Claiming today at 62 would permanently reduce that monthly benefit by around 30% compared to waiting until 67, while waiting past 67 up to age 70 would add roughly 8% a year on top of the full retirement amount.

Given her essential spending gap is modest and her portfolio can comfortably cover it for a handful of years, she chooses to delay Social Security and draw from her accounts instead to bridge the gap, letting her future benefit grow in the process. The gap is small enough for her portfolio to absorb without disrupting the overall plan, and the larger permanent check later becomes guaranteed income covering her essentials for life. For her bridge years, she pulls first from a taxable brokerage account built outside her retirement accounts, since those withdrawals are taxed more favorably than distributions from a pre-tax 403(b) or solo 401(k). She also uses part of those lower-income years to convert a modest slice of her pre-tax 403(b) into a Roth account each year, filling up her current tax bracket without spilling into the next one. This strategy works because she has roughly 13 years before RMDs begin at 75, and she’d rather control that taxable income on her own terms than have it forced all at once later. Her bond allocation is sized to cover her essential spending gap and that tail coverage bill with money that doesn’t need to ride out a market downturn, while the rest of her portfolio stays invested for the years still ahead. This example is hypothetical and doesn’t represent an actual client.

The Social Security timing, withdrawal order, and tail coverage expense only came together once her income needs and guaranteed income sources were laid out side by side, not by starting from a generic 62-year-old’s asset allocation.

If you take one thing from this episode, write down essential spending as a specific number, not a guess, including any Medicare or supplemental insurance premiums and, if it applies, a true tail malpractice payment for the year clinical work fully ends. Then line up every source of guaranteed or near-guaranteed income against that number, including Social Security, a pension if there is one, and any part-time income planned to continue. List out every retirement account being carried into retirement and roughly when RMDs will start forcing withdrawals from each one. That list, alongside the essential spending number, determines the order accounts should be withdrawn from, rather than which one happens to be easiest to log into. The gap between guaranteed income and essential spending is what determines how much of the portfolio needs to sit somewhere stable, and it’s also the number that should drive the Social Security claiming decision, not a default age everyone else happens to be using. What the income needs to cover, and when, decides more than any prediction about the stock market.
