Note: This is part 2 of the RMD series – part one is here: Requirement Distributions Explained

Understanding how much I have to withdraw is only half the RMD equation. The other half is understanding what happens after the money leaves my retirement account. For most Traditional IRAs, 401(k)s, and other tax deferred retirement accounts, the amount I withdraw generally becomes taxable income in the year I receive it. That means an RMD can affect much more than the balance in my IRA.

I might look at a $20,000 RMD and think I simply have another $20,000 available to spend. The reality can be quite different. Federal income taxes may take a portion of that money, and depending on my overall income, the additional taxable income could affect my Social Security taxation and Medicare premiums. What initially looks like a simple withdrawal can therefore create several financial consequences at once.

The important point is that an RMD is not a separate type of tax. It is taxable income that gets added to the rest of my income for the year. My tax bracket, deductions, other income, and overall financial situation determine how much I ultimately owe.

That is why I never want to look at an RMD in isolation. I want to consider it as one piece of my entire retirement income picture.

RMDs and Social Security Taxes

One of the biggest surprises for retirees involves Social Security.

I might have spent years thinking of my Social Security check as relatively predictable. Then my RMD begins, and suddenly more of my Social Security benefit may become taxable. The reason is that the IRS uses a formula based on my combined income to determine whether part of my Social Security benefits are subject to federal income tax.

For some retirees, as much as 85 percent of their Social Security benefits can become taxable. That does not mean I pay an 85 percent tax rate. It means up to 85 percent of the benefit can be included in taxable income.

The distinction matters.

Adding a substantial RMD to my other income can push me over one of the applicable thresholds. A larger portion of Social Security can then become taxable, increasing my overall tax bill. This is one reason I prefer to think several years ahead rather than waiting until my first RMD arrives. If I know that future distributions will increase my taxable income, I can explore strategies beforehand instead of reacting after the fact. RMDs Can Also Increase Medicare Premiums Medicare creates another potential surprise. Medicare Part B and Part D premiums can increase for higher income retirees because of the Income Related Monthly Adjustment Amount, commonly called IRMAA. The calculation generally looks at my modified adjusted gross income from two years earlier.

That two year lookback is important

Suppose I sell a large investment, complete a sizable Roth conversion, or take an unusually large retirement distribution in 2026. The resulting increase in income could affect my Medicare premiums in 2028.

I might have completely forgotten about the transaction by the time the higher Medicare bill arrives.

A large RMD can therefore create a ripple effect that extends beyond the year in which I take the distribution. For retirees living on a fixed income, an unexpected increase in Medicare premiums can be particularly frustrating.

I don’t want to discover this relationship after the fact. Reviewing projected taxable income before making major retirement account decisions gives me a much better chance of avoiding unpleasant surprises.

The Biggest RMD Mistake: Forgetting to Take It

The simplest RMD mistake may also be the easiest to avoid.

I can forget to take the required distribution.

That sounds almost impossible after reading about RMDs, but it happens every year. Retirees may have multiple accounts, several financial institutions, changing advisors, or complicated family finances. An RMD deadline can slip through the cracks surprisingly easily.

The consequences can be expensive.

Federal law has reduced the penalty structure for missed RMDs compared with the previous rules, but a missed distribution can still result in a significant penalty if I fail to correct the mistake. The IRS may also require additional paperwork when I request penalty relief.

My best defense is simple organization.

I want a written list of every retirement account that may require an RMD. I also want to know which institution calculates the distribution, when it will be taken, and whether I need to take any action myself. A calendar reminder several months before the end of the year can prevent a surprisingly expensive administrative mistake.

Taking Too Little Can Be a Problem

Another common error involves taking the wrong amount.

Suppose I have three Traditional IRAs and assume the brokerage firm will automatically calculate everything correctly. One account might calculate its portion accurately while another account gets overlooked. The problem becomes even more complicated when I have old employer retirement plans sitting at different financial institutions.

Multiple accounts require extra attention.

For Traditional IRAs, I can generally calculate the RMD for each IRA and then satisfy the combined requirement from one or more of those IRAs. Employer plans such as 401(k)s generally follow different aggregation rules, so I should not assume I can simply combine everything into one convenient withdrawal.

Keeping accurate records becomes increasingly important as my retirement accounts multiply.

Sometimes consolidating old retirement accounts can simplify the process. That decision should take into account investment choices, fees, creditor protection, tax considerations, and other factors, but reducing unnecessary account complexity can make retirement administration much easier.

The Roth Conversion Strategy

One of the most powerful ways I can manage future RMDs is through Roth conversions.

A Roth conversion moves money from a Traditional IRA or other eligible retirement account into a Roth IRA. I generally pay ordinary income tax on the converted amount, but qualified Roth withdrawals can later be tax free.

The bigger planning advantage is that Roth IRAs do not require lifetime RMDs for the original owner.

That creates an interesting opportunity during the years before RMDs begin. If my taxable income is relatively low after I retire, I may be able to convert portions of my Traditional IRA to a Roth IRA while staying within a favorable tax bracket.

I have to pay the tax now, so a Roth conversion is not automatically a good idea. The strategy works best when I compare the tax I would pay today with the potential tax savings and flexibility I could gain later.

Timing can make a significant difference.

A retiree who stops working at 65 but doesn’t begin RMDs until 73 may have several years to evaluate partial Roth conversions. Those years can create a valuable window for managing future taxable income.

Why I Don’t Want to Convert Everything at Once

Roth conversions can be powerful, but bigger isn’t necessarily better.

Converting a large Traditional IRA balance in one year could push me into a much higher tax bracket. It could also increase Medicare premiums later because of the IRMAA lookback.

A better strategy may involve converting smaller amounts over several years.

For example, suppose I have a $400,000 Traditional IRA and expect to have relatively modest taxable income during the next several years. Instead of converting the entire account at once, I might evaluate a series of annual conversions designed to stay within a target tax bracket.

That approach gives me greater control.

I can reassess the strategy each year based on tax law, investment performance, Social Security income, Medicare considerations, and my personal spending needs.

Tax planning works best when I treat it as an ongoing process rather than a one-time event.

Qualified Charitable Distributions Can Be Extremely Valuable

There is another RMD strategy that deserves much more attention from retirees who regularly give to charity.

A Qualified Charitable Distribution, or QCD, allows eligible IRA owners who are at least 70½ to make qualifying charitable donations directly from an IRA to an eligible charity, subject to annual IRS limits.

The important part is how the distribution is treated for tax purposes.

A properly structured QCD can satisfy all or part of my RMD while keeping the qualifying amount out of my taxable income. That can make a major difference for retirees who already donate to charity.

Consider a retiree who has a $20,000 RMD but doesn’t actually need the money. Instead of taking the entire distribution personally and then donating money to charity, the retiree may be able to have a qualifying portion transferred directly from the IRA to the charity.

The charitable contribution can count toward the RMD while the qualifying distribution generally does not become taxable income.

That distinction can be valuable because reducing adjusted gross income may also help with other parts of my financial picture.

QCD rules have specific requirements, so I want to make sure the distribution goes directly to an eligible charity and that the transaction is properly documented. This is one area where I would rather spend a few minutes confirming the rules than discover later that my generous donation didn’t receive the tax treatment I expected.

Do I Have to Spend My RMD?

Absolutely not. This is one of the biggest misconceptions I encounter.

The IRS requires me to take the money out of the retirement account, but it does not require me to spend it. Once I receive the distribution, I can use the money however I choose.

I might use it to pay living expenses, travel, healthcare costs, home improvements, or other retirement expenses. If I don’t need the money, I can move it into a taxable investment account, savings account, or another appropriate investment.

That flexibility is important because an RMD is a tax requirement, not a spending requirement.

Personally, I like the idea of treating an RMD as part of my overall retirement income plan rather than as an unexpected windfall. If I need the money, I use it. If I don’t, I give it a job somewhere else.

Retirement money should have a purpose.

Don’t Let an RMD Dictate Your Investment Strategy

Another mistake is changing an investment strategy simply because an RMD is approaching.

I don’t want to suddenly move a large percentage of my portfolio into cash because I know I have to make a withdrawal. Instead, I want to maintain an asset allocation that reflects my overall retirement goals and risk tolerance.

One practical approach is to keep enough relatively liquid assets to cover expected near term withdrawals while allowing the rest of the portfolio to remain invested according to my long term plan.

The exact allocation depends on my circumstances, but the principle is straightforward. I don’t want a mandatory withdrawal to force me into making an emotional investment decision.

Market downturns make this particularly important.

If stocks fall sharply just before I need to take an RMD, I may be tempted to sell investments simply because the calendar says I have to withdraw money. Having a broader income and cash management strategy can give me more flexibility.

What Happens When My RMD Becomes Larger?

RMDs don’t necessarily stay small forever.

As I get older, the IRS life expectancy factor decreases. If my account balance remains substantial, the required distribution can become a meaningful percentage of my portfolio.

That can create a tax planning challenge later in retirement.

I might have started retirement with a relatively modest taxable income, only to discover that investment growth and increasing RMDs have created a much larger taxable income problem in my seventies and eighties.

This is another reason I don’t want to wait until RMD age before thinking about taxes.

The best retirement tax strategy may involve decisions I make years earlier.

My RMD Checklist for Retirement Planning

When I think about RMD planning, I focus on several basic questions.

Do I know exactly which accounts require RMDs? Do I know when my first RMD is due? Have I calculated the amount correctly? Have I considered whether delaying the first distribution makes sense? Am I accounting for the potential effects on Social Security and Medicare? Have I evaluated whether Roth conversions could reduce future RMDs? If I donate to charity, should I consider a QCD?

Those questions don’t require me to become a tax expert.

They simply force me to look at the entire retirement picture rather than focusing on one account at a time.

The Bottom Line on Required Minimum Distributions

RMDs are one of those retirement topics that initially look much more complicated than they really are. Once I understand the basic rules, the calculation, the deadlines, and the tax consequences, I can approach them with considerably more confidence.

The biggest lesson I’ve learned is that RMD planning should start before the first RMD arrives. Waiting until age 73 can eliminate valuable opportunities for Roth conversions, tax bracket management, charitable giving strategies, and broader income planning.

I also don’t want to think of RMDs simply as money the government is forcing me to take. They are part of the retirement savings I accumulated over many years. The goal is to manage those withdrawals intelligently so I can use the money when I need it while keeping unnecessary taxes and penalties under control.

Retirement gives me something valuable that I didn’t always have during my working years, time. I can use some of that time to understand how my money works, plan ahead, and make deliberate decisions instead of reacting to tax rules after the fact.

The IRS will always have a seat at the retirement planning table. I just don’t have to give it the biggest chair.

A well-designed retirement plan considers RMDs alongside Social Security, Medicare, taxes, investments, charitable giving, estate planning, and spending needs. When all those pieces work together, Required Minimum Distributions become much less intimidating and much more manageable.

My goal isn’t to avoid taxes entirely. That’s rarely realistic. My goal is to pay what I legally owe, avoid unnecessary penalties, and make the most of the money I’ve spent a lifetime working to save.

That is what smart RMD planning is really about.
