Required Minimum Distributions explained

If you’ve been saving diligently in tax-deferred retirement accounts throughout your career, there’s an important milestone you need to understand before — or shortly after — you retire. Required minimum distributions are the amounts the IRS mandates you withdraw from certain retirement accounts once you reach a specific age. For retirees and pre-retirees here on the Treasure Coast, understanding required minimum distributions isn’t just a tax formality — it’s a critical piece of your overall retirement income strategy. Whether you’re enjoying morning walks along Bathtub Reef Beach or settling into the relaxed Stuart lifestyle, the last thing you want is an unexpected tax bill because you missed an RMD deadline.

What Are Required Minimum Distributions?

When you contribute to tax-deferred retirement accounts such as traditional IRAs, 401(k)s, 403(b)s, and other qualified plans, you receive a tax benefit upfront — your contributions reduce your taxable income in the year you make them. However, the IRS doesn’t let those funds grow tax-free forever. Required minimum distributions are the government’s way of ensuring that tax-deferred money eventually gets taxed. Think of it as the IRS saying, “We gave you a break on the way in, and now it’s time to start paying your share on the way out.”

Required minimum distributions apply to most tax-deferred retirement accounts, but notably they do not apply to Roth IRAs during the original account owner’s lifetime. This is because Roth contributions are made with after-tax dollars, so the IRS has already collected its share. However, inherited Roth IRAs may still be subject to distribution rules, which is something beneficiaries should be aware of when doing estate planning.

Understanding what required minimum distributions are — and which accounts they apply to — is the essential first step. From there, the key questions become: when do they start, how much do you have to take, and what happens if you don’t comply? Let’s walk through each of those questions together.

When Do Required Minimum Distributions Begin?

Thanks to the SECURE Act of 2019 and the SECURE 2.0 Act of 2022, the age at which required minimum distributions must begin has been pushed back in recent years. If you turned 73 in 2023 or later, your RMD start age is 73. Beginning in 2033, that age will increase again to 75. This is a meaningful change for Treasure Coast pre-retirees who are still a few years away from that threshold — it gives your investments additional time to potentially grow before you’re required to start withdrawing.

Your first required minimum distribution must be taken by April 1 of the year following the year you reach the applicable age. After that first year, each subsequent RMD must be withdrawn by December 31. Here’s an important nuance: if you delay your first distribution to April 1 of the following year, you’ll actually need to take two required minimum distributions in that second year — one for the prior year and one for the current year. That double distribution can push you into a higher tax bracket, which is something to plan for carefully.

For those still working past the RMD age, there is a limited exception. If you’re still employed and participating in your current employer’s 401(k), and you don’t own more than 5% of the company, you may be able to delay required minimum distributions from that specific plan until you retire. This exception does not apply to IRAs or former employer plans, so it’s narrower than many people realize. You can find more details on RMD rules and deadlines directly from the IRS retirement topics page.

How Required Minimum Distributions Are Calculated

Calculating your required minimum distributions involves a straightforward formula, though the inputs change each year. You take the prior year-end balance of your tax-deferred retirement account and divide it by a life expectancy factor from the IRS Uniform Lifetime Table. The IRS updated these tables in 2022, which slightly reduced RMD amounts for most retirees — a welcome change that allows a little more money to remain invested and growing.

For example, if your traditional IRA had a balance of $500,000 on December 31 of the prior year, and your life expectancy factor based on the table is 26.5 (roughly the factor for a 73-year-old), your required minimum distribution would be approximately $18,868 for that year. As you get older, the divisor gets smaller, which means your required minimum distributions increase over time — even if your account balance stays flat or decreases.

If you have multiple traditional IRAs, you calculate the RMD for each one separately, but you can actually take the total amount from any one or combination of your IRAs. This offers some flexibility in deciding which accounts to draw from. However, this aggregation rule applies only to IRAs — if you have multiple 401(k)s, the required minimum distribution for each plan must be taken from that specific plan. This distinction matters, especially if you’ve accumulated accounts across several employers over your career.

Tax Implications of RMDs for Florida Retirees

Here’s where living on the Treasure Coast provides a meaningful advantage. Florida has no state income tax, which means your required minimum distributions are only subject to federal income tax — not an additional state tax bite. For retirees who moved to Stuart or the surrounding Martin County area from high-tax states like New York, New Jersey, or Connecticut, this can represent significant savings over time. It’s one of the many financial benefits of retiring in Florida.

That said, federal taxes on required minimum distributions can still be substantial. RMD amounts are taxed as ordinary income, which means they’re added to your other income sources — Social Security benefits, pension payments, part-time work, and investment income. A large RMD could push you into a higher federal tax bracket, increase the taxable portion of your Social Security benefits, or trigger higher Medicare premiums through the Income-Related Monthly Adjustment Amount (IRMAA). Understanding how required minimum distributions interact with these other income streams is essential for effective retirement tax planning.

Many retirees are surprised to learn that their required minimum distributions can affect their Medicare costs two years down the road. Because IRMAA surcharges are based on your modified adjusted gross income from two years prior, a spike in income from a large RMD today could mean higher Part B and Part D premiums in the future. For a household enjoying retirement along the Treasure Coast, these ripple effects deserve careful attention and proactive planning.

Common RMD Mistakes and How to Avoid Them

The penalty for missing a required minimum distribution used to be one of the harshest in the tax code — a 50% excise tax on the amount not withdrawn. The SECURE 2.0 Act reduced that penalty to 25%, and it can be further reduced to 10% if you correct the shortfall in a timely manner. While these reduced penalties are an improvement, they’re still significant enough that you want to avoid the mistake altogether. Missing even a portion of your required minimum distributions is an expensive error.

One common mistake is forgetting about old retirement accounts. If you have a 401(k) from a job you left 20 years ago, it’s still subject to required minimum distributions once you reach the applicable age. Another frequent error is miscalculating the distribution amount because of confusion around which year-end balance to use or which life expectancy table applies. Inherited IRAs have their own set of rules that differ from those for original account owners, and mixing up these rules can lead to costly mistakes.

A third mistake that catches people off guard is assuming your financial institution will handle everything automatically. While many custodians offer RMD calculation services and even automatic distribution options, the ultimate responsibility for taking the correct required minimum distributions rests with you, the account holder. Setting calendar reminders, working with a financial professional, and reviewing your accounts annually are all good practices to stay on track.

Strategies to Manage Required Minimum Distributions Wisely

One popular approach is making Roth conversions before you reach RMD age. By strategically converting portions of your traditional IRA to a Roth IRA during lower-income years — perhaps in early retirement before Social Security kicks in — you can reduce the future balance subject to required minimum distributions. You’ll pay taxes on the converted amount now, but the money then grows tax-free in the Roth and isn’t subject to RMDs during your lifetime. This strategy requires careful planning to avoid pushing yourself into a higher tax bracket during the conversion years.

Another strategy for charitably inclined retirees is the Qualified Charitable Distribution (QCD). If you’re 70½ or older, you can direct up to $105,000 per year (as of 2024) from your IRA directly to a qualified charity. QCDs count toward satisfying your required minimum distributions but are excluded from your taxable income. For Treasure Coast retirees who already support local organizations, churches, or nonprofits, this can be a tax-efficient way to give while managing your RMD obligations.

Finally, consider the timing and coordination of your required minimum distributions with other income sources. Some retirees benefit from taking distributions early in the year to get them out of the way, while others prefer to wait until later in the year when they have a clearer picture of their total annual income. Coordinating RMDs with Social Security claiming decisions, pension income, and investment withdrawals is where thoughtful retirement income planning truly pays off.

Required minimum distributions may feel like just another box to check in retirement, but they touch nearly every aspect of your financial picture — from taxes and Medicare premiums to estate planning and charitable giving. The more you understand about how they work and the strategies available to manage them, the better positioned you’ll be to enjoy the retirement lifestyle you’ve worked so hard to build here on the Treasure Coast.
