If you’ve spent decades building a tax-deferred retirement account, there’s one rule the IRS will eventually enforce whether you’re ready or not: required minimum distributions. Starting at a certain age, the government requires you to begin withdrawing a portion of your traditional IRA, 401(k), or similar account each year — and if you miss the deadline or withdraw too little, the penalties can be steep. For retirees enjoying life on Florida’s Treasure Coast, understanding how required minimum distributions work isn’t just a tax formality. It’s a foundational piece of your retirement income strategy that touches everything from your Social Security benefit to your Medicare premiums. This guide breaks it all down in plain language so you can plan with confidence.

What Are Required Minimum Distributions?
Required minimum distributions are the annual amounts that the IRS mandates you withdraw from most tax-deferred retirement accounts once you reach a qualifying age. The logic behind the rule is straightforward: when you contributed to a traditional IRA or a workplace 401(k), you received a tax deduction or deferral on those contributions. The government was patient while your money grew — but it does expect its share of taxes eventually. Required minimum distributions are the mechanism that ensures the IRS collects income tax on those funds during your lifetime, rather than allowing the entire balance to pass tax-free to heirs. This rule applies to traditional IRAs, SEP-IRAs, SIMPLE IRAs, 401(k) plans, 403(b) plans, 457(b) plans, and most other defined contribution retirement accounts.
It’s worth noting that Roth IRAs are a notable exception to the required minimum distributions rule during the account owner’s lifetime. Because Roth contributions are made with after-tax dollars, the IRS has no further claim on that money while you’re alive. However, inherited Roth IRAs — accounts passed to non-spouse beneficiaries — do carry distribution requirements under current law. Understanding which of your accounts are subject to these rules is the first step in building a tax-efficient withdrawal strategy for your retirement years here in Stuart or anywhere along the Treasure Coast.
Many retirees are surprised to discover that required minimum distributions don’t just apply to their own accounts. If you’ve inherited a retirement account from someone other than a spouse, you may also be subject to distribution requirements on that inherited account. The rules for inherited IRAs changed significantly with the passage of the SECURE Act in 2019 and were further refined by SECURE 2.0 in 2022, making it more important than ever to review your situation with a qualified professional. You can find the official IRS guidance on these accounts at IRS.gov’s RMD resource page.
When Do Required Minimum Distributions Begin?
One of the most common questions retirees ask is simply: when do I have to start taking required minimum distributions? The answer has changed in recent years, and it depends largely on your birth year. Under the original SECURE Act passed in 2019, the starting age was raised from 70½ to 72. Then, with the passage of SECURE 2.0 at the end of 2022, Congress raised the age again. If you were born between 1951 and 1959, your required beginning date is age 73. If you were born in 1960 or later, the starting age increases further to 75. This phased-in timeline gives younger retirees more flexibility and additional years for tax planning before distributions become mandatory.
Your required beginning date — the actual deadline by which your first required minimum distributions must be taken — is April 1st of the year following the year you turn the applicable starting age. For example, if you turn 73 in 2025, your first RMD must be taken no later than April 1, 2026. After that first distribution, all subsequent required minimum distributions must be taken by December 31st of each calendar year. One important planning note: if you delay your first distribution until April 1st of the following year, you’ll be required to take two distributions in that same calendar year — your first-year RMD and your second-year RMD — which could push you into a higher tax bracket.
If you’re still working at the age when required minimum distributions would normally begin and you participate in your current employer’s 401(k) plan, a special exception may allow you to delay distributions from that specific plan until April 1st of the year after you retire. This “still working” exception does not apply to IRAs or to accounts held at former employers. Florida retirees who continue working part-time or consulting should verify with their plan administrator whether this exception applies to them, since the rules can vary by plan document. Staying informed now can protect you from an unexpected tax surprise later.
How to Calculate Your Annual RMD Amount
The calculation for required minimum distributions is simpler than many people expect, though it does require pulling together a couple of important figures. The IRS uses a formula: divide the account balance as of December 31st of the prior year by a life expectancy factor found in the IRS Uniform Lifetime Table. The IRS publishes updated tables in Publication 590-B, and the figures were revised in 2022 to reflect longer life expectancies, which generally means smaller annual distributions than under the older tables. You’ll find the official tables and examples directly on the IRS Publication 590-B page.
To illustrate, if your traditional IRA balance was $500,000 on December 31st of the prior year and your IRS life expectancy factor at age 73 is 26.5, your required minimum distributions for the current year would be approximately $18,868. As you age, the life expectancy factor decreases, which means a larger percentage of your account is required to be distributed each year. By age 80, the distribution percentage rises, and by age 90, it increases substantially. This gradual increase is by design — the IRS expects a larger share of your remaining balance to be taxed as you move through retirement.
If you hold multiple IRAs, you must calculate the required minimum distributions separately for each account, but you have the flexibility to satisfy the total combined amount by withdrawing from any one or combination of your IRA accounts. That flexibility does not extend across different account types, though. Your 401(k) or 403(b) distributions must be taken from each respective workplace plan separately and cannot be aggregated with your IRA distributions. For Treasure Coast retirees managing multiple rollover IRAs alongside an old workplace plan, keeping a clear inventory of all your accounts is an essential part of staying organized and compliant each year.
The Tax Impact of RMDs on Your Retirement Income
Understanding the tax consequences of required minimum distributions is just as important as knowing how to calculate them. Because distributions from traditional IRAs and 401(k)s are treated as ordinary income, they stack on top of your other income sources — Social Security, pension payments, rental income, and investment earnings — and can affect your overall tax bracket in meaningful ways. For retirees in Florida, there’s good news: the state has no personal income tax, so your required minimum distributions are only subject to federal taxation. That’s one of the genuine financial advantages of retiring here on the Treasure Coast.
However, the federal implications still deserve close attention. Required minimum distributions can trigger or increase something called IRMAA — Income-Related Monthly Adjustment Amounts — which are surcharges added to your Medicare Part B and Part D premiums when your income exceeds certain thresholds. Medicare uses your income from two years prior to determine your current year’s premiums, so a large RMD in one year can raise your Medicare costs two years down the road. You can learn more about how income affects Medicare premiums directly at Medicare.gov. This is one reason proactive tax planning around required minimum distributions is so valuable for retirees.
Additionally, higher taxable income from required minimum distributions can affect the taxability of your Social Security benefits. Up to 85% of your Social Security benefit may be subject to federal income tax if your combined income exceeds certain thresholds. For married couples filing jointly, this threshold is relatively modest, and even a moderate RMD can push you into the zone where a greater portion of your Social Security becomes taxable. Understanding how these income streams interact with one another is one of the most compelling reasons to think about required minimum distributions not just as a tax obligation, but as a retirement income planning opportunity.
Smart Strategies for Managing Your Distributions
One of the most widely discussed strategies for managing the tax burden of required minimum distributions is the Roth conversion. In the years between retirement and when your RMDs begin, you may be in a lower tax bracket than you were during your working years. Converting a portion of your traditional IRA to a Roth IRA during this “tax window” reduces the balance subject to future required minimum distributions, potentially lowering your taxable income in later years. Conversions are taxable in the year they occur, so careful planning is essential — converting too much in a single year can push you into a higher bracket or trigger IRMAA surcharges.
Another powerful strategy involves what’s known as a Qualified Charitable Distribution, or QCD. If you’re age 70½ or older, you can direct up to $105,000 per year (indexed for inflation) from your IRA directly to a qualified charity. When done correctly, a QCD counts toward satisfying your required minimum distributions for the year without adding the amount to your taxable income. For charitably inclined retirees along the Treasure Coast who support local organizations, churches, or community foundations, this strategy can be both philanthropically meaningful and financially efficient. It’s one of those rare win-win opportunities in the tax code.
Timing also plays a meaningful role in RMD planning. Rather than taking your full distribution in a single lump sum in December, some retirees benefit from spreading distributions throughout the year to smooth out their income and simplify cash flow management. Others choose to reinvest distributions they don’t need for living expenses into a taxable brokerage account, maintaining their investment exposure while fulfilling the IRS requirement. At The 1715 Podcast’s financial planning hub, we discuss these strategies regularly because the right approach is genuinely different for every household, depending on income sources, account balances, and long-term legacy goals.
Common RMD Mistakes and How to Avoid Them
Missing a required minimum distribution deadline is one of the most costly errors a retiree can make. Historically, the penalty for failing to take the full required amount was a 50% excise tax on the shortfall — meaning if you were supposed to withdraw $20,000 and didn’t, you could owe a $10,000 penalty on top of the regular income tax. SECURE 2.0 reduced this penalty to 25%, and further to 10% if the mistake is corrected promptly within two years. While those reductions are welcome, the penalty is still significant enough to take seriously. Putting a recurring reminder on your calendar or setting up automatic distributions through your account custodian can prevent this costly oversight entirely.
Another frequent mistake is failing to account for all accounts subject to required minimum distributions. Many retirees have multiple IRAs — perhaps a rollover from an old employer, an IRA opened years ago, and a spousal IRA. Each account carries its own balance that must be included in the total RMD calculation, even if the actual withdrawal can come from any single IRA. Workplace plans like 401(k)s must be calculated and distributed separately. Overlooking even one account can result in an underpayment that triggers the excise tax. Maintaining a comprehensive account inventory and reviewing it at the start of each year is a simple habit that pays dividends.
A subtler mistake involves the required minimum distributions for inherited accounts. Many beneficiaries don’t realize they have distribution obligations on inherited IRAs, or they misunderstand the 10-year rule that now applies to most non-spouse beneficiaries under the SECURE Act. Under this rule, the entire inherited IRA balance must generally be distributed within 10 years of the original owner’s death. Failing to understand this timeline — and to plan for the tax consequences of accelerated distributions — can result in both penalties and unexpected tax bills. If you’ve recently inherited a retirement account, speaking with a qualified financial professional early in the process is strongly advisable.
Putting It All Together
Required minimum distributions are one of those retirement planning topics that can feel complicated on the surface but become much more manageable once you understand the core rules and the planning tools available to you. Knowing when your distributions must begin, how to calculate them accurately, and how they interact with your broader income picture — from Social Security to Medicare premiums — puts you in a far stronger position than simply reacting when the deadline arrives. The retirees who navigate this phase of financial life most gracefully are typically those who started thinking about required minimum distributions several years before they were obligated to take them.
For Treasure Coast retirees, the absence of Florida state income tax is a genuine advantage, but it doesn’t eliminate the need for thoughtful federal tax planning around your distributions. Whether you’re considering Roth conversions, Qualified Charitable Distributions, or simply optimizing the timing of your withdrawals, there are real dollars at stake in how you approach these decisions. The strategies that work best depend on your specific account balances, income sources, family goals, and risk tolerance — which is why personalized guidance matters so much in this area.
