Introduction: The Withdrawal Question Nobody Warned You About

You spent decades accumulating money for retirement. You watched the balance grow, made contributions, and perhaps rolled over accounts from job to job. But here’s the part that often catches retirees off guard: how you take money out matters almost as much as how much you saved.

Taxes don’t stop in retirement. In fact, for many people, retirement is when taxes become more complicated — because now you’re coordinating Social Security, Required Minimum Distributions (RMDs), investment income, pension payments, and perhaps part-time work, all at once. Each source of income can affect how much tax you owe on the others.

For retirees on Florida’s Treasure Coast — from Port St. Lucie to Stuart to Vero Beach — this complexity is very real. Florida has no state income tax, which is a significant advantage. But federal income taxes still apply to most retirement income, and without a thoughtful withdrawal strategy, retirees can inadvertently push themselves into higher tax brackets, trigger Medicare surcharges, or leave their heirs a larger tax bill than necessary.

This guide walks through the key concepts of tax-efficient retirement withdrawals. It is educational in nature and is not personalized tax or financial advice — but by the time you finish reading, you’ll understand the landscape well enough to have a much more productive conversation with your financial planner and tax professional.

1. Know Your Account Types: The Three Tax Buckets

Before you can develop a withdrawal strategy, you need to understand where your money is sitting — and more importantly, how the IRS treats each type of account when you pull money out.

Financial planners often refer to three broad “buckets” of money:

The sequence in which you draw from these buckets — and the amounts you pull from each — directly shapes your annual tax bill. Most people have the majority of their savings in Bucket 1, which is why RMDs and bracket management are so central to retirement tax planning.

2. Withdrawal Order: Conventional Wisdom vs. Strategic Sequencing

The traditional advice was simple: spend your taxable accounts first, then tax-deferred accounts, then Roth accounts last (since they grow tax-free the longest). This approach makes intuitive sense, but it’s not always optimal.

The problem with following that rule rigidly is that it can cause large tax-deferred accounts to grow unchecked into your early retirement years, leading to massive RMDs later that push you into higher brackets, increase taxes on Social Security benefits, and trigger Medicare Income-Related Monthly Adjustment Amounts (IRMAA surcharges — more on those shortly).

A more strategic approach involves filling the brackets — intentionally drawing from your traditional IRA or 401(k) up to the top of a lower tax bracket in years when your income is relatively modest. This reduces the size of future RMDs and may allow more of your savings to convert to tax-free status over time.

For example, if your standard deduction and other income leave you well below the top of the 22% or 24% federal tax bracket, it may make sense to voluntarily take additional distributions — even if you don’t need the cash immediately — rather than let the account grow and face larger forced distributions later.

The right withdrawal order depends on your specific income sources, account balances, estimated future RMDs, Social Security timing, and tax bracket projections. There is no single universal answer.

3. Roth Conversions: Paying Taxes Now to Potentially Save More Later

A Roth conversion is the process of moving money from a traditional IRA or 401(k) into a Roth IRA. You pay income tax on the amount converted in the year of the conversion, but the money then grows tax-free and future qualified withdrawals are not taxed.

The years between retirement and age 73 (when RMDs begin) — sometimes called the “conversion window” — can be an especially valuable time for Roth conversions. Why? Because many newly retired people experience a temporary dip in taxable income before Social Security and RMDs kick in. This dip creates an opportunity to convert at lower marginal rates than you might face later.

Key considerations for Roth conversions:

• Tax bracket impact: Conversions add to your ordinary income for the year. Converting too much can push you into a higher bracket or affect Medicare premiums two years later.
• Five-year rule: Converted funds must remain in the Roth for five years (and you must be 59½) before they can be withdrawn tax- and penalty-free. This matters less if you’re not planning to touch the Roth soon.
• Estate planning benefit: Roth IRAs pass to heirs income-tax-free, making them a powerful legacy tool — especially if your children are in higher tax brackets.
• State tax note: Because Florida has no state income tax, Treasure Coast retirees may find conversions marginally more attractive than residents in high-tax states.

Roth conversions are not right for everyone. If you expect your tax rate to be lower in the future, or if paying the conversion tax would require liquidating investments at a bad time, the math may not favor it. A qualified financial planner and CPA can help you model the scenarios.

4. Social Security Taxation and RMDs: The Hidden Interaction

Many retirees are surprised to learn that Social Security benefits can be taxable — up to 85% of your benefit may be included in your taxable income depending on your “combined income” (also called provisional income). This is your adjusted gross income, plus nontaxable interest, plus half of your Social Security benefit.

Here’s why this matters for withdrawal strategy: every dollar you pull from a traditional IRA increases your adjusted gross income, which in turn can increase the portion of your Social Security benefit that’s taxable. This creates a compounding tax effect that is easy to overlook but can meaningfully affect your net income.

Required Minimum Distributions add another layer of complexity. Beginning at age 73, the IRS requires you to withdraw a minimum amount from your traditional IRAs and most employer retirement plans each year. The formula is based on your account balance divided by an IRS life expectancy factor. Larger account balances mean larger RMDs — which can push you into higher brackets and increase Social Security taxation simultaneously.

One strategy to address this: Qualified Charitable Distributions (QCDs). If you are 70½ or older and charitably inclined, you can direct up to $105,000 per year (2024 limit, indexed for inflation) from your IRA directly to a qualified charity. This counts toward your RMD but is excluded from your taxable income — meaning it doesn’t inflate your Social Security tax calculation or push you into a higher bracket. For retirees who donate regularly, this can be a highly efficient strategy.

Social Security timing also interacts with withdrawal strategy. Delaying Social Security to age 70 increases your monthly benefit by approximately 8% per year beyond full retirement age — but it also means you’ll need to draw more from your portfolio in the interim. Whether that trade-off makes sense depends on your health, other income sources, and how your accounts are positioned.

5. Medicare IRMAA Surcharges: The Tax That Sneaks Up Two Years Later

Medicare Part B and Part D premiums are not fixed for everyone. If your income exceeds certain thresholds, you pay more — a surcharge known as IRMAA (Income-Related Monthly Adjustment Amount). In 2024, the standard Part B premium is $174.70 per month. But at higher income levels, this can rise to over $594 per month per person.

Here’s the critical detail: Medicare uses your tax return from two years prior to determine IRMAA. So your 2024 premiums are based on your 2022 income. A large Roth conversion, a one-time asset sale, or a higher-than-expected RMD in a given year can trigger IRMAA surcharges two years later — even if your income in the surcharge year is much lower.

For married couples, both spouses are affected individually, so the cost can double. A couple with combined income just over the first IRMAA threshold could pay thousands more per year in Medicare premiums than a couple with income just below it.

IRMAA thresholds (which adjust annually) create “cliff” effects — where a modest income increase causes a disproportionately large cost increase. Careful income management in retirement, including deliberate timing of Roth conversions and large withdrawals, can help avoid these cliffs.

If your income drops significantly (due to retirement, loss of a spouse, or other life event), you can appeal IRMAA using Form SSA-44, providing documentation of the change. This is worth knowing if you experience a sudden income shift.

6. Asset Location: It’s Not Just What You Own, But Where You Own It

Asset location is the practice of placing different types of investments in the account type best suited to their tax treatment. This is distinct from asset allocation (how you divide between stocks, bonds, and other assets).

The general principle: investments that generate higher ordinary income (like bonds paying interest, REITs paying dividends) are often better held in tax-deferred or tax-free accounts, while investments with more favorable tax treatment (like index funds or individual stocks held long-term) may be more appropriate in taxable accounts where gains are taxed at lower capital gains rates.

In retirement, this matters because you’re actively drawing income. If your taxable brokerage account holds highly appreciated investments, you may want to be intentional about when you sell — favoring years when your income is lower to qualify for the 0% long-term capital gains rate (which, in 2024, applies to taxable income up to approximately $47,025 for single filers and $94,050 for married filing jointly).

Asset location strategies work best when you have money spread across all three bucket types and when your overall portfolio is managed with tax efficiency in mind. It’s one more reason why coordination between your financial planner and tax professional is valuable.

7. Retiring on Florida’s Treasure Coast: Tax Advantages and Local Considerations

Florida is consistently ranked among the most tax-friendly states for retirees, and for good reason:

• No state income tax: Florida does not tax wages, Social Security, pension income, IRA distributions, or investment income at the state level. This means your federal tax return is your primary tax concern.
• No estate or inheritance tax: Florida eliminated its estate tax in 2004 and has no inheritance tax, which can simplify legacy planning.
• Homestead exemption: Florida’s homestead exemption can reduce the assessed value of your primary residence for property tax purposes — worth understanding if you own a home in Martin, St. Lucie, or Indian River County.
• Save Our Homes cap: Limits annual increases in assessed value for homesteaded properties to 3% or the CPI increase, whichever is lower — providing property tax stability for long-term residents.

However, Florida retirees still owe federal income taxes on most retirement income. And if you previously lived in a high-tax state and moved to the Treasure Coast for retirement, be sure your prior state can no longer claim you as a resident — domicile rules vary, and some states aggressively audit former residents.

The combination of no state income tax, warm weather, and no state estate tax makes Florida genuinely advantageous for retirement income planning — but federal planning remains essential, and the strategies outlined in this guide apply fully to Treasure Coast retirees.
