The window between retirement and RMDs is one of the best tax planning opportunities of your life.

A Quick History Lesson

The federal income tax did not exist until 1913. By 1944 the top marginal rate hit 94%. Not a typo. To be fair that only applied to people making over $200,000 per year which back in the 1940s was big money.

Ronald Reagan used to tell this story on the campaign trail. As a Hollywood actor in the late 1940s he was making one hundred thousand dollars per feature film. However he would never make more than two per year, because anything after that he would hit that 94% tax bracket, meaning on a third movie he would only keep 6 cents of every dollar. So he stopped working for the year. His words: why would he do another picture even if it was Gone with the Wind? What good would it have done him?

You can disagree with his politics. The math is still the math.

The top rate stayed above 90% through most of the 1950s. Kennedy brought it down to 70%. Reagan eventually got it to 28%. Today it sits at 37% for the highest earners.

Why This Matters Right Now

By historical standards tax rates today are relatively low. We are not here to make a political argument. We are here to point out what the numbers show.

We also have a national debt growing faster than you can watch on a screen. People a lot smarter than me have looked at that number and asked how it gets resolved. The answer many of them land on is that taxes will eventually need to go up. Not because anyone wants them to. Because the math demands it.

We are not predicting the future. We are asking you to think about probability.

Traditional or Roth?

When you contribute to a traditional 403(b) or IRA you get a tax break today. The money goes in pre-tax and grows over time. Sounds great. But here is what a lot of people do not fully appreciate.

Let's say you contribute $100,000 over the course of your career and it grows to $250,000. The IRS does not just tax your $100,000 contribution. They tax the entire $250,000. Every dollar of growth is taxable income the moment you start pulling it out.

A Roth works the exact opposite way. You get no tax break going in. But that $250,000 is entirely tax-free. And if it keeps growing in retirement it stays tax-free. Forever.

Roth Conversions

A Roth conversion moves money from a pre-tax account into a Roth, you pay the taxes now and the money grows tax-free forever after. Simple concept. Requires careful execution.

Done wrong it can push you into a higher bracket than necessary. It can make your Social Security benefits taxable when they would not have been otherwise. It can trigger IRMAA surcharges, higher Medicare premiums that genuinely catch people off guard.

Done right a multi-year conversion strategy spreads the tax hit across several years, keeps you in the best brackets possible, and can save you real money over a long retirement. We model it out for every client before making any recommendation.

The Window

Between leaving the classroom and the age when required minimum distributions kick in, either 73 or 75 depending on your birth year under current law, you have one of the best tax planning windows of your financial life.

Income drops. Your tax bracket drops with it. Your 403(b) has not started forcing distributions yet. You can move pre-tax dollars into Roth at a lower rate than you paid during your working years and potentially lower than you will pay when those distributions are forced.

That window does not stay open forever. Paying taxes on the seeds beats paying taxes on the harvest, especially when the harvest might be taxed at a higher rate than today. This ties directly into Social Security timing → and your broader retirement income plan →.
