Don’t retire yet if you’re missing key readiness items—tax plan, withdrawal strategy, Social Security/Medicare timing, and risk controls—for $500K–$5M households

You can be “financially close” to retirement and still be unready.

I see this all the time with households in the $500,000 to $5 million range: the savings are real, the desire to retire is real, and the plan is… a collection of good ideas that don’t yet work together. That gap is where avoidable taxes, Medicare surprises, and income stress tend to show up.

Here’s the tension: retiring is not just stopping work. It’s switching your entire financial system from accumulation (save and invest) to distribution (spend and protect). If you make that switch without a coordinated tax plan, withdrawal strategy, Social Security and Medicare timing, and risk controls, you can accidentally lock in penalties and higher lifetime costs that are hard to unwind.

This article is a fiduciary “readiness filter” for $500K–$5M households. It’s not meant to scare you. It’s meant to help you pick a retirement date you can defend.

If even one or two of these red flags describe you, my advice is simple: don’t retire yet. Pause the date long enough to fix the plan.

The readiness filter: what “coordinated” actually means at $500K–$5M

At this asset level, your biggest retirement risks usually aren’t “Did you save enough?” They’re coordination risks.

Coordination means your decisions reinforce each other instead of colliding.

A coordinated retirement plan answers, in plain English:

1) How much income will you need, and where will it come from each year?

2) Which accounts will you pull from first, and why?

3) How will you keep taxes from spiking later (especially when RMDs start)?

4) When will you claim Social Security, and what’s the tradeoff?

5) When will you enroll in Medicare, and how will you avoid penalties and IRMAA surprises?

6) How much market risk are you taking, and is it the right kind of risk?

7) If something happens to you or your spouse, does the plan still work?

If you want the “income” side of this in more depth, we built a supporting guide on how to build a retirement paycheck plan here: /post/retirement-paycheck-plan-500k-5m.

Now let’s get specific.

Red flag #1: You’re retiring without a written withdrawal strategy (not just a budget)

What it looks like

You have a sense of spending. You may even have a spreadsheet. But you don’t have a clear, repeatable system for turning your accounts into income.

So the default becomes: “We’ll just pull from the IRA when we need it,” or “We’ll live off dividends,” or “We’ll sell a little from the brokerage account.”

Why it matters

In retirement, the order you withdraw from accounts can change your taxes, Medicare premiums, and how long your money lasts.

A withdrawal strategy is not the same as a spending plan.

A spending plan answers: “How much do we spend?”

A withdrawal strategy answers: “Which dollars do we spend first, second, and third, and what does that do to taxes and long-term outcomes?”

This is where many $500K–$5M households unintentionally:

- Trigger higher Medicare premiums later (IRMAA)

- Push themselves into higher tax brackets in their 70s

- Create bigger Required Minimum Distributions (RMDs) than necessary

- Sell investments at the wrong time because they didn’t set up a cash buffer

Quick self-test

If the market drops 20% the month after you retire, can you answer these questions without guessing?

- Which account do you pull from for the next 12 months?

- How much cash do you already have set aside for spending?

- What would you sell (and what would you refuse to sell) in a down market?

If the answer is “We’ll figure it out,” that’s a red flag.

The planning move that fixes it

Build a withdrawal map that includes:

- A 12–24 month “spending reserve” (cash or very short-term bonds) so you’re not forced to sell stocks during a bad stretch

- A tax-aware withdrawal order (taxable, IRA/401(k), Roth) that fits your situation

- A rule for when to refill cash (for example, after strong market quarters)

If you want a deeper dive on the withdrawal order and why it matters, see our supporting article on tax-efficient withdrawal strategy: /post/tax-efficient-withdrawal-strategies-retirement.

Red flag #2: Your tax plan is “we’ll be in a lower bracket in retirement”

What it looks like

You assume taxes will drop once your paycheck stops.

Sometimes that’s true. Often it’s not.

Why it matters

For many affluent retirees, the “low-tax years” are a short window—often between retirement and the start of Social Security and RMDs.

Then taxes can rise again because:

- Social Security becomes taxable (depending on your other income)

- RMDs force income out of pre-tax accounts

- Capital gains from brokerage sales stack on top

- One-time events happen (a big home sale, a business sale, an inheritance, a Roth conversion)

Also, Medicare premiums are tied to income. Higher income can mean higher Medicare costs through IRMAA (Income-Related Monthly Adjustment Amount). That’s not a tax, but it feels like one.

Quick self-test

Look at your current retirement accounts.

- If most of your money is in pre-tax accounts (traditional IRA/401(k)), do you know what your RMDs might look like later?

- Do you know what tax bracket you’ll likely be in at 73, 75, and 80?

- Do you know what income level triggers higher Medicare premiums for you?

If you haven’t modeled those years, you don’t have a tax plan. You have a hope.

The planning move that fixes it

You need a multi-year tax plan, not a one-year tax estimate.

In our work, a practical tax plan for retirees usually includes:

- A “tax bracket target” during the early retirement window (fill a bracket on purpose rather than accidentally spilling into a higher one later)

- A plan for managing capital gains (especially if you’ll be living partly off a brokerage account)

- A strategy for reducing future RMDs

We have a full supporting guide on reducing future RMDs here: /post/rmd-planning-reduce-required-minimum-distributions.

And if Roth conversions are part of your plan (often they are in the early retirement window), start here: /post/roth-conversions-retirement-tax-window.

Important note: tax planning should be coordinated with your CPA. As a fiduciary advisor, I’m looking at the strategy and the long-term tradeoffs; your CPA helps execute and file correctly.

Red flag #3: You’re claiming Social Security based on a “break-even age” and ignoring the real tradeoffs

What it looks like

You’re deciding between 62, full retirement age, or 70 based on a simple break-even calculation.

Or you’re claiming early because “I want to get something back.”

Or you’re delaying because “it’s always better to wait.”

All three can be wrong depending on your household.

Why it matters

Social Security is one of the only inflation-adjusted income streams most retirees have. It’s also a decision that affects the surviving spouse.

The higher earner’s benefit matters a lot because when one spouse dies, one Social Security check typically goes away and the survivor keeps the larger of the two.

Also, Social Security interacts with taxes and Medicare.

- More Social Security can mean more taxable income later

- Claiming while still working (before full retirement age) can reduce benefits due to the earnings test

Quick self-test

Answer these questions:

- Who is the higher earner, and what would the survivor live on?

- Are you retiring before full retirement age but still earning income (consulting, part-time, business income)?

- Do you have enough assets to “bridge” spending if you delay Social Security?

If you haven’t looked at Social Security as a household decision (not an individual one), that’s a red flag.

The planning move that fixes it

A good claiming strategy usually weighs four things:

1) Longevity risk (living a long time)

2) Survivor protection (what happens to the spouse who lives longer)

3) Tax coordination (what your income looks like in your 60s vs 70s)

4) Portfolio risk (can your investments support a delay without forcing bad sales?)

For a deeper guide, see our Social Security claiming strategy article: /post/social-security-claiming-high-earners.

Red flag #4: Medicare is “something we’ll handle when we turn 65”

What it looks like

You’re within a year or two of 65 and you haven’t mapped out:

- When you’ll enroll

- What coverage you’ll choose (Original Medicare + supplement vs Medicare Advantage)

- Whether you’re delaying because you have employer coverage

- Whether your income could trigger IRMAA surcharges

Why it matters

Medicare has enrollment windows. Miss them and you can face late enrollment penalties.

Medicare also has cost layers that surprise people:

- Premiums (Part B and Part D)

- Deductibles and copays

- Drug coverage differences

- IRMAA surcharges if your income is above certain thresholds

IRMAA is one of the most common “I didn’t see that coming” moments for affluent retirees.

It often happens after:

- A large IRA withdrawal

- A Roth conversion year

- Selling a highly appreciated investment

- A one-time income event

Quick self-test

- Are you retiring before 65 and need coverage in the gap years?

- Do you know your Initial Enrollment Period (it starts three months before you turn 65 and ends three months after)?

- Do you know if a planned Roth conversion or large withdrawal could raise Medicare premiums two years later?

If you’re unsure, that’s a red flag.

The planning move that fixes it

Coordinate Medicare with your tax plan.

That means:

- Mapping income not just for next year, but for the next 3–5 years

- Timing large income events intentionally

- Avoiding “accidental” income spikes that push you into higher IRMAA brackets

We have a dedicated supporting article on Medicare enrollment timing and IRMAA traps here: /post/medicare-enrollment-deadlines-irmaa-traps.

Red flag #5: Your portfolio is built for growth, but your retirement needs stability

What it looks like

Your investments may be fine in a 401(k) context, but retirement changes the job of the portfolio.

Common patterns I see:

- Too much concentration in one stock (often employer stock)

- Too much “income investing” (chasing dividends) without understanding the risk

- A portfolio that’s aggressive on paper but has no plan for withdrawals in a downturn

- A portfolio that’s overly conservative because the fear of loss is louder than the math

Why it matters

The big risk early in retirement is sequence risk.

Sequence risk is simple: if the market drops early and you’re withdrawing at the same time, you can do permanent damage to the plan even if markets recover later.

This is not about predicting crashes. It’s about building a structure that can survive them.

Quick self-test

- If your portfolio dropped 15–25%, would your spending plan change?

- Do you have a cash reserve so you can avoid selling stocks during a downturn?

- Are you relying on dividends alone to fund spending?

Dividends feel comforting, but they are not guaranteed. Companies can cut them. And a dividend-focused portfolio can still drop sharply.

The planning move that fixes it

For retirees, I prefer thinking in “roles” rather than labels.

- Money you need in the next 1–2 years should have a stability role.

- Money you need in 3–7 years should have a balance role.

- Money you need beyond that can have a growth role.

That role-based approach helps you avoid two common mistakes:

1) Taking too much risk with near-term spending money

2) Taking too little risk with long-term money, which can quietly increase the risk of running out

This is also where rebalancing rules matter. A portfolio without a rebalancing discipline is a portfolio that drifts into unintended risk.

Red flag #6: You haven’t planned for RMDs, and you’re assuming they’re a “small detail”

What it looks like

You know RMDs exist, but you treat them like a future paperwork item.

Why it matters

RMDs are forced taxable withdrawals from most pre-tax retirement accounts.

They can:

- Push you into higher tax brackets later

- Increase the taxable portion of Social Security

- Increase Medicare premiums via IRMAA

- Create a “tax spike” in your 70s and 80s that you could have smoothed earlier

Also, missing an RMD can trigger a major penalty. The IRS has historically assessed a 50% penalty for failure to take an RMD (plus the tax you owed). The point isn’t the exact number—it’s that the penalty is severe enough that you don’t want RMDs on autopilot without a system.

Quick self-test

- Do you know roughly how large your first RMD could be?

- Do you know which accounts will have RMDs (and which won’t, like Roth IRAs)?

- Do you have a plan for what you’ll do with the RMD if you don’t need to spend it?

If not, that’s a red flag.

The planning move that fixes it

RMD planning is really tax planning.

Common tools include:

- Partial Roth conversions in lower-income years

- Coordinating withdrawals so you’re not forced into large RMDs later

- Charitable strategies for those who give (in the right situations)

Start with our supporting guide on reducing future RMDs: /post/rmd-planning-reduce-required-minimum-distributions.

Red flag #7: Your estate plan and account structure don’t match your retirement plan

What it looks like

You have a will. Maybe a trust. But it hasn’t been reviewed since before retirement.

Or your beneficiary designations haven’t been updated.

Or you have accounts scattered across old 401(k)s, multiple custodians, and different titling styles.

Why it matters

In retirement, estate planning isn’t just about who gets what when you die.

It’s also about:

- Who can make decisions if you can’t

- How smoothly your spouse can access money

- Whether your beneficiaries inherit accounts in a tax-smart way

- Whether your plan unintentionally creates delays, legal costs, or tax headaches

For $500K–$5M households, the “big miss” is usually not fancy trusts.

It’s basics done poorly:

- Outdated beneficiaries

- No coordination between the trust and the account titling

- No clear plan for the surviving spouse’s tax situation (often a higher tax rate after one spouse dies)

Quick self-test

- When was the last time you reviewed beneficiaries on IRAs, 401(k)s, and life insurance?

- Do you know who has financial power of attorney?

- If one spouse dies, do you know how income and taxes change for the survivor?

If these aren’t clear, that’s a red flag.

The planning move that fixes it

Coordinate your estate attorney, CPA, and advisor around one shared “retirement map.”

That includes:

- Beneficiary review

- Account titling review

- A survivor plan (income, taxes, and investment risk after the first death)

This is one of the most overlooked areas because it feels morbid. In practice, it’s one of the most loving things you can do for your spouse.

A realistic example: the “almost ready” couple with $1.8M who could retire now—but shouldn’t (yet)

Let me show you how this plays out.

Assume a couple, both 63, with $1.8 million invested:

- $1.1M in traditional IRAs/401(k)s

- $450k in a taxable brokerage account

- $250k in Roth IRAs

They want to retire this year. Their spending need is $95,000 after tax.

On the surface, they’re fine.

But here’s what we find when we run a coordinated plan:

1) They planned to claim Social Security at 63 because “we’ll invest the checks.”

In their case, delaying the higher earner’s benefit meaningfully improves survivor protection. That’s not theory—it changes the surviving spouse’s paycheck for life.

2) They planned to take most withdrawals from the IRA.

That creates higher taxable income in their 60s, which raises the chance of IRMAA later and reduces the ability to do Roth conversions in lower brackets.

3) They had no plan for the 65–70 window.

This is often the best tax planning window of retirement. If you miss it, you can’t get it back.

4) Their portfolio was 80% stock with no spending reserve.

They were one bad market year away from selling stocks at a discount to fund spending.

The fix wasn’t complicated, but it required coordination:

- Build a two-year spending reserve

- Use the taxable account strategically in early retirement

- Run a measured Roth conversion plan in the “gap years” (while watching IRMAA)

- Delay Social Security for the higher earner to improve lifetime and survivor outcomes

- Set a rebalancing rule so risk doesn’t drift

In this case, the best move was not “work five more years.”

It was “work six to twelve more months, set the system up correctly, then retire with confidence.”

That’s the kind of tradeoff I like: small delay, big clarity.

The questions retirees are asking right now (and my direct answers)

Am I financially prepared to retire with $500K to $5M in assets?

Maybe. Asset level alone doesn’t answer it. Prepared means your income plan survives a bad market early, your taxes are mapped for multiple years, and healthcare timing is handled. If you can’t explain your withdrawal order and Medicare plan in one minute, you’re probably not ready yet.

How can I maximize my Social Security benefits before retiring?

Stop thinking “maximize” and start thinking “optimize for your household.” The higher earner’s decision often matters most because it affects the survivor. Also consider whether you’ll work before full retirement age, because earnings can reduce benefits temporarily.

What are the tax implications of withdrawing from my retirement accounts?

Traditional IRA/401(k) withdrawals are generally taxed as ordinary income. They stack on top of other income and can raise the taxable portion of Social Security and Medicare premiums. The key is not avoiding taxes entirely—it’s controlling when you pay them and at what rate.

When should I start Medicare enrollment to avoid penalties?

Your Initial Enrollment Period starts three months before you turn 65 and ends three months after. If you miss it (and you don’t have qualifying coverage), you can face late enrollment penalties. Also, if you’re retiring before 65, you need a bridge plan for healthcare.

How can I plan for healthcare costs in retirement?

Don’t just budget premiums. Plan for the full system: premiums, deductibles, drug costs, and the possibility of higher premiums due to IRMAA. And if long-term care is a concern, treat it as a separate planning conversation—because it’s not the same as routine medical spending.

The “don’t retire yet” action list: 12 items to lock down before you set the date

If you’re within 0–24 months of retirement, this is the checklist I want you to complete.

1) Write down your target retirement date and your “backup date.”

2) Define your spending in two layers:

- Needs (housing, food, insurance, healthcare)

- Wants (travel, gifting, hobbies)

3) Build a retirement paycheck plan (income sources by year).

If you need a framework, start here: /post/retirement-paycheck-plan-500k-5m.

4) Create a withdrawal order and a rebalancing rule.

For the tax side, see: /post/tax-efficient-withdrawal-strategies-retirement.

5) Identify your “gap years” (retirement to Social Security to RMDs).

Those years are often your best planning window.

6) Run a multi-year tax projection.

Not perfect. Just realistic enough to see bracket changes and future spikes.

7) Evaluate Roth conversions intentionally.

Start here: /post/roth-conversions-retirement-tax-window.

8) Estimate future RMDs and decide whether you want to reduce them.

Start here: /post/rmd-planning-reduce-required-minimum-distributions.

9) Decide on a Social Security claiming strategy as a household.

Start here: /post/social-security-claiming-high-earners.

10) Map Medicare enrollment timing and IRMAA risk.

Start here: /post/medicare-enrollment-deadlines-irmaa-traps.

11) Stress-test the plan against three scenarios:

- A bad market early in retirement

- One spouse living into their 90s

- A major healthcare event

12) Coordinate beneficiaries, account titling, and estate documents.

Your retirement plan should not fall apart because paperwork is outdated.

If you do these 12 items well, you’ll be ahead of most retirees—not because you found a trick, but because you built a system.

My fiduciary point of view: what’s overrated, underrated, and misunderstood

Overrated: retiring the moment you “hit your number.”

A number without coordination is fragile. I’d rather see a slightly smaller portfolio with a strong tax and income system than a larger portfolio with guesswork.

Overrated: dividend-only retirement income.

Dividends can be part of the plan. They are not a plan. Total return matters, taxes matter, and flexibility matters.

Underrated: the first 5 years of retirement.

This is where sequence risk lives. It’s also where many of your best tax moves live.

Underrated: delaying retirement briefly to set the plan.

Working “one more year” is not always the answer. But working long enough to build the structure is often a high-return decision.

Misunderstood: “I’ll be in a lower tax bracket later.”

Sometimes. But many $500K–$5M households see taxes rise again due to RMDs, Social Security taxation, and Medicare premiums. The goal is smoothing, not guessing.

Misunderstood: Medicare is just a healthcare decision.

It’s also an income and tax decision because your premiums can change based on income.

If you want help, here’s what a Retirement Readiness Review should cover

If you’re considering hiring a fiduciary advisor for this transition, I’d look for a process that does four things in one coordinated conversation:

- Retirement income planning: how the paycheck works, year by year

- Tax planning: bracket management, Roth conversion analysis, RMD forecasting

- Social Security and Medicare timing: claiming strategy, enrollment deadlines, IRMAA awareness

- Portfolio risk controls: cash reserves, rebalancing rules, concentration risk, withdrawal stress-testing

That’s the difference between “investment management” and retirement planning.
