Retirement Tax Trap (Avoid This $250k Mistake)

I've been doing retirement planning for over 30 years. If most of your retirement savings are in a 401k or traditional IRA, there is a point where the IRS starts choosing your income for you. Not because you overspent, not because the market crashed. It's because of how your money is structured. I call this tax concentration risk.
Today, I'm going to show you exactly when that shift happens, how much it can cost over, say, 10 years, and what you can still do about it before your control disappears.
Let's walk through a typical example. Let's take John and Mary. They want to retire at age 62. They've got about $2.5 million of total investable assets. No risky investing here, no crazy spending. And most advisers, by the way, they would put a check mark or their stamp of approval on this kind of plan. The issue is the structure.
Before we go further, mentally calculate this. What percentage of your total retirement savings is pre-tax? If it is more than 60%, this conversation applies directly to you. Either way, keep listening to see where you can improve.
So, here is John and Mary's mix. They have about $1.7 million pre-tax, about $500,000 in their brokerage, and there's $250,000 in their Roth IRA. Now, they want about $120,000 of income per year. Here's the translation. About 70% of their wealth sits in one tax environment. That doesn't feel urgent at age 62. That's exactly why it becomes so expensive later.
They delay Social Security to age 70. Their plan assumes about a 7.5% growth rate and about 3% of spending increases or inflation. Nothing extreme here. Everything seems pretty normal.
If you're watching this and you are between 60 and 70 years old right now, these are your most flexible years. This is when bracket management, tax bracket management that is, is still optional. After 73 years old, it is not. That is the age where control quietly shifts. If you're age 60 to 70 and still in control of your income, this is the window where things like voluntary Roth conversions or intentional tax bracket management can materially change the trajectory before the IRS forces the issue.
Most plans tend to stop here. But this is exactly where the trap is being built because the question is not will the portfolio last. The question is who controls the timing of income once the IRS shows up.
So let's get back to John and Mary. This is standard planning in the early retirement years from 62 to 70. They draw mostly from their brokerage account. Taxes feel manageable. The portfolio likely keeps growing. Now, this is the decade where retirees will feel most in control. And that sense of control is exactly what hides the problem. At 73, the rules change. This is where we go next.
At 73, you have required minimum distributions. Here they are. They begin, and you can't stop them. This is the age where the IRS forces money out of your IRA whether you need it or not. If you do not know, by the way, your projected IRA balance at 73, you are planning blind. You should know that number within a reasonable range. By the way, if your advisor has never shown you a projected RMD at age 73, ask him or her for that model.
Okay, so John and Mary, their IRAs have grown now to roughly $3 million. The first RMD should be around $115,000. Now, let's layer some income. They have 60,000 of Social Security, $25,000 in dividends from their investment accounts. Total income approaching 200K.
Now, watch what happens. Taxable Social Security just increased. In fact, 85% of their Social Security will be considered ordinary income and it will be taxed as ordinary income. The marginal tax brackets rise. Medicare begins to respond through what we know as IRMAA. Nothing dramatic here. In fact, you might be saying this is just how it is.
But something subtle just disappeared. It's your choice. In other words, the tax code is now dictating the income. Once you hit 73, it's not up to you. And once that begins, it doesn't reverse. At that point, your flexibility is mathematically limited. And this isn't a mistake that just occurred. It happened many years ago.
I know what you're thinking. What should have been happening between 62 and 72 while income was still optional? Not extreme moves, not risky investing, intentional bracket management, strategic Roth conversions, purposeful distribution sequencing. That's what should have been happening. We're not going to unpack all of that today. But understand this, the years before 73 are not passive years. Those are positioning years. And you have to use them while you can.
And when those years are ignored, the compression you are seeing at 73 is not surprising, or at least it shouldn't be. It's mathematical. If you want us to elaborate on this subject in another video, please let us know in the comments. We'll be sure to get that out very soon.
Now, let's extend this from age 73 to 83. RMDs are going to continue. Remember, they're mandatory starting at age 73. Income remains elevated. Federal taxes are now accumulating. Medicare premiums, they're going to stay in the higher tiers. Over a decade, the cumulative tax paid is materially higher than it needed to be. In a scenario like this, the 10-year difference can easily exceed a quarter of a million dollars depending on state and federal taxes and your growth assumptions.
To make matters worse, this didn't happen because of overspending. Wasn't because of market losses either. Actually, this kind of thing could hinder your spending, could force you to change your lifestyle. At the very least, inheritances could take a haircut. All of this because the earlier years were not used intentionally and no one bothered to tell you. Retirement tax pressure compounds and it does it very quietly.
Now, if you're early in retirement, the question should not be, "How little tax can I pay this year?" The better question is, am I intentionally filling lower tax brackets while I can? I say this because once brackets are forced higher by RMDs, the opportunity is gone and you won't get it back.
Now, let's scale this. What if we were talking about a $7 million portfolio versus the two and a half that John and Mary started with? The pressure doesn't soften, it accelerates. The RMD is no longer $115,000. Now it's closer to $300,000. And the tax bracket compression intensifies. IRMAA escalates. Flexibility is narrowing faster.
The more successful you are, the more expensive poor structure becomes. And that's rarely discussed early enough. I can't tell you why this gets ignored, but it's likely because advice rarely gets focused on tax or other complicated areas of planning.
Now, there's one more structural shift that we have not modeled at this point. What happens if one spouse dies at say 75? They have the same IRAs, same income, but the tax brackets are now smaller. The math doesn't get easier here, but it does compress. This is not something that you want to discover after the fact.
This scenario didn't involve risky investing or a market collapse or even lifestyle creep. It involved concentration in one tax bucket in the absence of bracket management during early retirement when you could have done something about it.
Retirement planning isn't about predicting markets. Markets will do what they do. Returns are created through good selection of securities and patience. Investments are important, but retirement planning must include how income moves through the tax code over time. We refer to this as tax environments, and every dollar of your earnings, growth, retirement plans, and hard assets, and even inheritances move through a tax environment. When that movement isn't modeled intentionally, control narrows, and it happens quietly. Sometimes it's never detected until it's too late.
Now, in our next video, we're going to walk through the specific strategies that can reduce this kind of pressure, including tax bracket management, Roth repositioning, and timing adjustments that can materially change the outcome. Click or tap the screen to watch it
