The $5.1 Million Tax Bill, Nobody Warned Him About
How a $1.7 million 401(k) becomes a $5.1 million tax bill, and what to do before Age 67.
The Compound Effect
I sat down with a client recently who had $1.7 million in his 401(k). He called into our office because he was ready to be done. His job in sales was changing, and he could see the writing on the wall with a new change in leadership.
Previously, he had actually worked with a financial advisor and had an additional $450,000 over there. He was looking to consolidate things, and he had heard great things about our firm from a family member.
Reviewing his financial plan, he appeared almost bullet proof. We could reduce the risk in his portfolio but overall, he was in a great position to never run out of money.
Once we had the basics of retirement accounted for, we immediately shifted his attention to the first world problems of having a good nest egg; taxes and estate planning.
Rolling his financial plan into the future visually in front of him, a number appeared that left him speechless. $5.1 million in projected lifetime taxes, he couldn’t take his eyes off of the screen.
“How has this never been called to my attention? Is there anything that can be done?”
That’s the response every client has when they realize that there’s two sides to compounding wealth, growth and taxes.
That’s what I call the compound effect.
Paying Tax on the Seed vs the Harvest
When you contribute to a 401(k) or IRA, you’re making a deal with the government.
They let you defer taxes now in exchange for access later.
No taxes on the contributions going in, they are even kind enough to give you a tax deduction, and no taxes on the growth while it compounds. You get to watch your account build for decades and there’s zero friction or cause for concern.
The analogy that I always give is that it’s like choosing to pay taxes on the seed or paying taxes on the harvest. By taking the deduction today you’re agreeing to let your silent partner, the federal government, get a cut of the harvest.
Which is worth more, seed today or a plentiful harvest in the future? The harvest in our case is when that $1 you invest becomes $5 in twenty years or $10 in forty years.
At 73 or 75, depending on the year you were born, the IRS comes to collect. The official term is a Required Minimum Distribution. You can call it what it is: a forced withdrawal.
Each year, you take your account balance from December 31st of the prior year, divide it by a life expectancy factor from an IRS table, and that’s your required amount you must pull from your account.
Miss it or take less than your silent partner demands? The penalty is 25% of whatever you didn’t withdraw. This is on top of the income taxes you still owe.
Knowing these conditions exist, you want to make sure you have the appropriate balance between paying taxes on the seed versus the harvest in your financial planning.
The Compounding Trap Nobody Sees Coming
Here’s what caught my client completely off guard, and it catches most people the same way.
He was a conservative spender. Not because he had to be. Just by nature. He didn’t live extravagantly, didn’t plan to, and figured his $1.7 million would carry him through retirement with room to spare.
He was right. His money was going to outlast him comfortably. That was the problem.
Because his spending was conservative, his portfolio kept growing faster than he was drawing it down. A bigger balance means a bigger RMD. Not a little bigger.
Each year, the balance climbs, the life expectancy factor drops, and the required withdrawal goes up again. The IRS table doesn’t care how frugal you are. It sees the balance.
By age 75, his projected RMDs were set to hit $180,000 per year and climbing every year after that. On his current trajectory, the total tax bill across a 35-year retirement landed at $5.1 million.
He’d saved $1.7 million. He was on track to pay three times that in taxes.
The IRS has a very good business model.
And before you assume this is a problem reserved for high earners, run the math on your own accounts.
If your portfolio balance is reasonable and your spending is modest, the same dynamic is at work.
The specific numbers change. The trap doesn’t.
How RMDs Make Everything Else More Expensive
Required distributions don’t generate a tax bill in isolation. They create ripple effects across your entire retirement income picture, and most people don’t see any of them coming.
Your RMD adds to your ordinary taxable income for the year. The larger that income, the more of your Social Security benefits become taxable.
Single filers above $34,000 in provisional income can see up to 85% of their Social Security benefit subject to federal income tax. Most retirees with sizable RMDs get there faster than they expect.
Then there’s Medicare. The program uses your income from two years prior to set your Part B and Part D premiums. These surcharges, called IRMAA, can add several thousand dollars per year to what you’re paying.
A large RMD in 2026 shows up in your Medicare bill in 2028. You were forced to make a decision in one year and paid for it in two more.
When federal taxes, state taxes, Social Security taxation, and Medicare surcharges all stack together, the effective rate on a retirement dollar can exceed 40%.
I’m trying not to spill my coffee as I tell you that. It’s an ugly number. Most people have no idea it’s waiting for them.
The Golden Window Most People Treat Like a Waiting Room
There’s a stretch of years between roughly ages 59 and 67 that doesn’t get nearly enough attention in most retirement conversations.
At 59 and a half, the 10% early withdrawal penalty on retirement accounts disappears.
Many people are beginning to retire or scale back to part-time work during this window in time, dropping their income.
Social Security hasn’t started yet. RMDs are years away. For the first time in your financial life, you have real control over your taxable income.
This is the window opportunity. And most people treat it like a waiting room.
It’s not a waiting room. It’s the operating room. The decisions made during this window are where lifetime tax savings are actually built.
The tool that does the most work here is called a Roth conversion. You move money from your traditional IRA or 401(k) into a Roth IRA.
You pay income taxes on that amount now, at today’s rates. After that, the money grows tax-free and you never owe RMDs on it during your lifetime.
The strategy isn’t to convert everything at once. That would push you into the worst bracket possible.
The strategy is bracket-filling. Each year, during this window, you convert just enough to fill your current bracket without spilling into the next one. Then you do it again next year.
Filling the Bracket: What the Numbers Actually Look Like
Back to my client with $1.7 million.
By filling up the 24% tax bracket each year between now and age 75, we are saving him $4.2 million in lifetime taxes. That $4.2 million in tax savings generates another $3.8 million in investment growth.
The growth is fueled by the converted dollars that are now compounding inside a Roth account, tax-free, instead of sitting in a pre-tax account waiting to get taxed at a higher rate later.
Even a more conservative approach, filling only the 22% bracket each year, saves him $1.6 million.
The tax planning alone is projected to add 0.66% annually to his portfolio’s effective rate of return.
Most people spend significant energy chasing an extra fraction of a percent in investment performance. They pay almost no attention to the tax drag running quietly in the background.
This is the better place to look.
He sat back in his chair and said, “Why didn’t anyone ever tell me this?”
That is the question I hear more than any other.
What To Do This Week
Pull up your retirement account balances. Add them together. Now project what that number looks like at 75 if your portfolio grows at even a modest rate and your spending stays conservative.
Use the IRS Uniform Lifetime Table to calculate what your RMD would be at that balance.
If the number surprises you, good. That’s the first step.
Then look at your current taxable income for this year. The difference between where you are and the top of your tax bracket is your potential Roth conversion budget for 2026.
That’s real money you can move to tax-free growth before this window closes.
My client had $1.7 million saved and a $5.1 million tax bill he didn’t know existed.
Twelve months from now, he’s on an entirely different trajectory. The window is open.
The comments are where you can pull up a chair. If you’ve run your numbers and the RMD projection surprised you, I’d genuinely like to hear about it.
Onyx Eclipse
I recently just picked up a bag of Onyx Eclipse at the flagship Onyx location in Rogers, Arkansas. If you’re ever traveling or passing through Northwest Arkansas it’s a must visit location.
In the past I’ve only had Onyx’s fruitier acidic and Southern Weather blends. Southern Weather is one of my favorite roasts I’ve ever had, period. This time however, I branched out and bought their Eclipse which is a dark roast.
I fired that baby up in my Moccamaster the next morning, oh man is it good.
If you enjoy a dark roast and do not like acidic stuff, it is right up your alley. It’s not bitter, in fact it’s very smooth for being a dark roast. I highly recommend it!
May your taxes stay low and your mugs forever full, cheers!

Converting an employer plan account or Traditional IRA to a Roth IRA is a taxable event. Increased taxable income from the Roth IRA conversion may have several consequences including but not limited to, a need for additional tax withholding or estimated tax payments, the loss of certain tax deductions and credits, and higher taxes on Social Security benefits and higher Medicare premiums. Be sure to consult with a qualified tax advisor before making any decisions regarding your IRA.
