The account that made you wealthy could cost your family a fortune.

If you spent thirty or forty years funding a 401(k) and an IRA, you did what every good plan told you to do, and you deferred the taxes on all of it. What nobody showed you is what that deferral costs once Required Minimum Distributions begin, when the IRS decides how much comes out each year and which bracket it lands in. That is the knowledge gap. This book puts that number on paper with your own figures, and it shows you the window you still have to do something about it before the schedule closes.

The arithmetic
$243,000

The raise your silent partner gives themselves while you do all the work.

Imagine you have $1 million in your IRA at age 63. Over the next twelve years, it grows to about $2 million. That sounds like good news, and it is. But a bigger balance can also mean a bigger tax bill when you take the money out.

In this example, the estimated tax on that money grows from $240,000 to about $483,000. That is roughly $243,000 more that could go to taxes instead of supporting your retirement or your family.

The takeaway: what matters is not just how much your account grows. It is how much you get to keep.

At age 63: IRA balance $1,000,000, estimated tax share $240,000. Twelve years later: illustrative balance roughly $2,012,000, estimated tax share roughly $483,000, assuming a 24% tax rate. Illustration only, not a guaranteed return.
Illustration only. Returns are not guaranteed; assumes a 24% future tax rate.

Illustration only, assuming a traditional IRA grows 6% a year for twelve years and withdrawals are taxed at 24%. Returns and future tax rates are not guaranteed. Your actual taxes depend on when and how you withdraw the money and your personal circumstances.

Who it's for

Written for the people who saved well and were never shown the bill.

1

You have $500,000 or more in pre-tax accounts

Traditional IRAs, rollover IRAs, 401(k)s, 403(b)s. The bigger the balance, the bigger the partner's claim, and the more a plan is worth.

2

You're somewhere between 58 and 72

The stretch between your last paycheck and your first required withdrawal is the Conversion Window. It is one of the best windows for retirement tax planning, and it closes on a schedule.

3

You're married and have never run the numbers as one

When one spouse passes, the survivor loses roughly half their bracket room overnight. The same dollars get taxed harder. This book shows you how to plan for it while you are both still here.
