I have advised business owners for decades on matters of wealth and retirement, and few topics generate as much confusion and last-minute anxiety as Required Minimum Distributions, or RMDs. For an employee with a single 401(k), the rules are relatively straightforward. But for your average business owner, the situation is almost always more complex. You aren’t just an employee; you are the architect of your company’s retirement plan, a participant in it, and often its most significant beneficiary. This unique position means RMDs aren’t just a personal tax event; they are a strategic business consideration that, if mismanaged, can trigger unnecessary tax liabilities and disrupt careful estate plans. In this article, I will dissect the world of RMDs from your perspective, moving beyond the basic rules to explore the advanced strategies and critical pitfalls that define smart planning for successful entrepreneurs.
Understanding the core “why” behind RMDs is the first step to mastering them. The US government offers a powerful incentive to save for retirement: tax deferral. Money goes into your qualified plans pre-tax, it grows tax-deferred for decades, and you only pay ordinary income tax when you take it out. RMDs are the government’s way of finally collecting that revenue. They mandate that you must begin withdrawing a minimum amount from most tax-advantaged retirement accounts starting at a certain age. The logic is simple—the tax code cannot allow you to defer taxes indefinitely. The Setting Every Community Up for Retirement Enhancement (SECURE) Act of 2019, followed by SECURE 2.0 in 2022, significantly changed the RMD landscape. The most critical change for those not yet taking distributions was the increase in the starting age. For individuals born in 1951 or later, RMDs now begin at age 73. If you were born in 1960 or later, the age moves to 75. This delay provides a valuable few extra years of tax-deferred growth.
The calculation of your RMD amount is a mechanical process, but one you must understand. The formula is not based on your contributions or your needs; it is based on your life expectancy. For each retirement account subject to RMDs (excluding Roth IRAs, which have no RMDs for the original owner), you take the account balance as of December 31 of the previous year and divide it by a life expectancy factor published by the IRS in Uniform Lifetime Table. The most common table is the Uniform Lifetime Table, used by most unmarried owners and owners whose spouse is not more than ten years younger and is not the sole beneficiary.
The formula is: RMD = \frac{Account Balance on Dec 31}{Life Expectancy Factor}
For example, imagine I am a business owner turning 73 in 2024. The IRS life expectancy factor for a 73-year-old is 24.7. If my 401(k) balance was $2,500,000 on December 31, 2023, my RMD for 2024 would be calculated as: RMD = \frac{\$2,500,000}{24.7} = \$101,214.57 I must withdraw at least this amount in 2024 to avoid a severe penalty.
The following table provides a snapshot of how the life expectancy factor declines with age, increasing the percentage you must withdraw.
Table 1: IRS Uniform Lifetime Table Excerpt
| Age | Life Expectancy Factor | Effective RMD Percentage |
|---|---|---|
| 72 | 27.4 | 3.65% |
| 73 | 24.7 | 4.05% |
| 74 | 23.8 | 4.20% |
| 75 | 22.9 | 4.37% |
| 80 | 18.7 | 5.35% |
| 85 | 14.8 | 6.76% |
For a business owner, the plot thickens considerably because you likely have multiple accounts. The rules for aggregating RMDs are not uniform and are a common source of error.
- IRAs (Traditional, SEP, SIMPLE): You can calculate the RMD for each IRA separately, but you have the option to take the total combined RMD amount from any one or more of your IRAs. This offers significant flexibility in managing which assets to liquidate.
- Employer Plans (401(k), Profit-Sharing, 403(b)): The rules are stricter. You must calculate and take the RMD separately from each employer plan. You cannot take the RMD for your 401(k) from your IRA, or vice versa. This is crucial if you have old 401(k)s from previous businesses or a current plan for your active company.
This distinction is where I see many business owners make their first major mistake. They assume all retirement money is treated the same for distribution purposes, but the IRS draws a clear line between IRAs and employer-sponsored plans.
The tax impact of RMDs is their most consequential feature. Every dollar you withdraw from a traditional retirement account is treated as ordinary income. For a successful business owner, these mandatory distributions can easily push you into a higher tax bracket. This is not a theoretical concern; it is a practical reality that can affect your Medicare Part B and D premiums through Income-Related Monthly Adjustment Amount (IRMAA) surcharges and diminish the efficiency of your other tax strategies.
The penalty for failing to take your full RMD is deliberately harsh, designed to ensure compliance. The excise tax is 25% of the amount not distributed. The SECURE 2.0 Act did reduce this from 50%, but it remains a steep penalty. Furthermore, if you correct the error in a timely manner, the penalty may be reduced to 10%. Nevertheless, this is not a penalty any rational planner should risk incurring.
For the business owner who is still actively working past age 73, a powerful exception exists, but it comes with strict limitations. The “still-working exception” allows you to delay taking RMDs from your current employer’s qualified plan (like a 401(k)) until April 1 of the year after you retire. However, this exception has critical caveats:
- It only applies to the plan of the company where you are currently employed, not to plans from previous employers or IRAs.
- You must not own more than 5% of the company. This “5% owner” rule is a trap for many business founders. If you hold more than a 5% stake in your business, you are considered an owner-employee and are not eligible for the still-working exception. Your RMDs from that company’s plan must begin at age 73 or 75, regardless of your employment status.
This rule exists to prevent owners from using their position to indefinitely postpone taxes on their largest retirement accounts. If you are a majority owner, you must plan for RMDs to begin on the standard schedule.
Given these complexities, proactive planning is not a luxury; it is a necessity. Waiting until the year you turn 73 to think about RMDs means you have already lost valuable planning time. Here are the strategies I discuss with my business owner clients years in advance.
Strategic Roth Conversions: This is often the most powerful tool in our arsenal. A Roth conversion involves moving funds from a traditional IRA or 401(k) into a Roth IRA. You pay ordinary income tax on the converted amount in the year of the conversion, but the money then grows tax-free forever and is not subject to RMDs. The goal is to execute these conversions in years where your income is lower—perhaps after you’ve stopped drawing a large salary but before Social Security and RMDs begin. By systematically “filling up” a lower tax bracket with conversion amounts over several years, we can reduce the future size of your tax-deferred accounts, thereby lowering your future RMDs and their associated tax burden.
Qualified Charitable Distributions (QCDs): If you are charitably inclined, QCDs are a remarkably efficient strategy. Once you reach age 70½, you can direct up to $105,000 annually (as of 2024, indexed for inflation) from your IRA directly to a qualified charity. This distribution counts toward your RMD but is not included in your adjusted gross income (AGI). This provides a tax benefit even if you do not itemize deductions, and it helps keep your AGI low, potentially reducing those IRMAA surcharges and preserving other tax benefits.
Asset Location and Allocation: In the years leading up to RMDs, we can strategically position investments. Placing high-growth assets like stocks in Roth accounts (where growth is tax-free) and placing slower-growing, income-producing assets like bonds in traditional IRAs (where RMDs will eventually be taxed as income) can optimize the overall tax efficiency of your portfolio.
For the business owner, your company itself can be part of the RMD solution. If cash flow from the business is strong, you may not need to rely on your RMDs for living expenses. This “problem” of excess income can be managed by reinvesting the after-tax portion of the RMDs into a taxable brokerage account, where it can continue to grow, now taxed at preferable long-term capital gains rates. Furthermore, the type of retirement plan you establish for your business can influence your future RMD burden. While all traditional defined contribution plans are subject to RMDs, designing a plan with a Roth 401(k) option gives you and your employees a choice to build a pool of tax-free retirement assets.
Estate planning is the final, critical frontier of RMD strategy. The rules for inherited retirement accounts have been drastically altered by the SECURE Act. Most non-spouse beneficiaries (like your children) are now subject to a 10-year rule, requiring them to fully distribute an inherited IRA within ten years of your death. This accelerates the tax liability and makes the account type you leave behind incredibly important. Leaving a large traditional IRA could force your heirs into their highest tax brackets. In contrast, leaving a Roth IRA provides them with tax-free income. This makes a long-term Roth conversion strategy even more compelling, as it can be a form of tax-efficient wealth transfer.
In my practice, I frame RMDs not as a punishment, but as the final, inevitable phase of a long-term tax strategy that began with your first retirement plan contribution. For a business owner, navigating them successfully requires a holistic view that integrates personal finance, corporate structure, and estate goals. By understanding the rules years in advance, leveraging strategic conversions, and utilizing charitable tools, you can transform a potential tax burden into a manageable, and even advantageous, component of your financial legacy. The key is to start the conversation early. The decisions you make today will directly determine the tax efficiency of your tomorrows.
