The Tax Bill You're Building Right Now Without Knowing It
Here is a number worth sitting with.
If you are 60 years old with $800,000 in a traditional IRA, and you earn a modest 6% annually between now and age 73, you will arrive at your first Required Minimum Distribution with roughly $1.7 million in that account.
You did not add a dollar to it. You simply left it alone.
The IRS will require you to withdraw approximately $63,000 from that account in year one. Not because you need the money. Because the law says so. And the following year, a little more. And the year after that, a little more still — because the account, if it continues to grow, keeps generating larger and larger mandatory withdrawals for the rest of your life.
If you have a spouse, a pension, Social Security, and a taxable brokerage account on top of that IRA, you can see where this goes. Your income in retirement — the income you cannot control, the income the government schedules for you — may be significantly higher than your income today.
Why this is a planning problem, not a math problem
The instinct most people have is to leave pre-tax money alone for as long as possible. Let it compound. Defer the taxes. That instinct is correct during the accumulation phase, when your income is high, and your bracket reflects it.
It stops being correct the moment you retire.
Between retirement and age 73 — the gap years — something unusual happens. Your earned income stops. Social Security may not have started. Your RMDs haven't kicked in. For many people, this is the lowest-income period of their adult lives. The 22% bracket. Sometimes the 12%.
That window is an opportunity. A temporary one.
Every dollar sitting in a traditional IRA during that window is a dollar that will eventually be forced out at whatever rate applies when the RMDs begin — which, given the compounding math above, is likely to be a higher rate than the one available to you right now.
The RMD time bomb is not a surprise. It is a predictable, mathematical outcome of leaving pre-tax money untouched through a low-bracket window. The only question is whether you use the window or let it close.
What using the window looks like
It means taking money out of your traditional IRA before you have to — paying the tax now, at the lower rate, and moving the proceeds into a Roth account where they will grow tax-free and never generate an RMD.
It means running the numbers year by year: how much can you convert before you hit the next bracket threshold, before IRMAA kicks in, before Social Security taxation increases. These constraints interact with each other, which is why the math cannot be done once and filed away. It is a multi-year plan, recalibrated annually.
Done well, a coordinated Roth conversion strategy through the gap years can reduce your lifetime tax liability by tens of thousands of dollars — in some cases more — without changing a single investment.
If you want this done for you
I built something for exactly this situation. It is called the Tax-Protected Income Blueprint — a written, CPA-produced planning deliverable that maps your retirement tax picture across the gap years, models your RMD trajectory, identifies your optimal conversion path, and gives you a specific, year-by-year plan.
It is not a template. It is not a spreadsheet you fill in yourself. It is a 15-page document produced for your household, your numbers, and your timeline.
If you are within five years of retirement or recently retired, and most of your savings is in pre-tax accounts, this is the engagement I built for you.
