Roth Conversions in Retirement: How Much and When?

Roth conversions can be one of the most valuable decisions you make in retirement.

They can also be one of the most expensive.

Both are true.

The difference isn’t the strategy.

It’s how you use it.

Most people think Roth conversions are a “yes or no” decision.

They’re not.

As I wrote in Retire Today—and shared with clients for years:

Roth conversions are not “yes or no.”
They are “how much?” and “when?”

That’s where the real planning happens.

No pressure. Just a conversation to see if we can help.

This page isn’t about whether Roth conversions are “good” or “bad.”

It’s about:

How to make better decisions about them—year by year

Because this isn’t a one-time choice.

It’s an ongoing strategy.

What is a Roth conversion

A Roth conversion is when you move money from a pre-tax account (like a traditional IRA or 401(k)) into a Roth account.

When you do that:

  • You pay taxes today
  • So you don’t pay taxes later

Simple.

But simple doesn’t mean easy.

The Golden Rule of Roth Conversions

Before tax laws changed…
After tax laws changed…

The Golden Rule of Roth conversions remains:

Choose the right year and the right amount of Roth conversions

That’s it.

Not:

  • Convert everything
  • Never convert
  • Convert up to the top of your current bracket every year

Those are shortcuts.

And shortcuts are where mistakes happen.

Where most advisors stop short

Many advisors focus on investments.

Some focus on retirement planning.

But very few coordinate how tax decisions like Roth conversions fit into everything else:

  • Your income plan
  • Your withdrawal strategy
  • Your Medicare costs
  • Your long-term tax picture

Roth conversions don’t exist on their own.

They affect everything around them.

And when they’re not coordinated, that’s where small decisions can create larger costs over time.

Why Roth conversions are easy to get wrong

Most mistakes don’t come from bad intentions.

They come from assumptions.

You’ve seen both sides:

  • People stop doing conversions because “tax rates aren’t going up anymore”
  • Others keep converting aggressively because “they’ve always done them”

Both are reacting.

Not planning.

The recent tax law didn’t remove the need to think.
It just removed the excuse not to.

What Roth conversions are actually trying to do

The goal isn’t to avoid taxes.

It’s to:

Pay taxes when your rates are lower
Avoid paying higher taxes later when possible

That might mean:

  • Converting some money now
  • Leaving some for later
  • Adjusting year by year

This is not a one-time decision.

The real Roth conversion questions to ask

Instead of asking:

“Should I do a Roth conversion?”

Ask:

  • How much should I convert this year?
  • Which tax bracket should I fill up?
  • What about Affordable Care Act Premium Tax Credits this year?
  • What about IRMAA Medicare costs in two years?
  • What happens if I convert more?
  • What happens if I convert less?

That’s where the strategy lives.

Your Roth conversion opportunity years

There are certain periods where Roth conversions tend to be more valuable.

Often (but not always):

  • After you retire
  • Before you start Social Security
  • Before RMDs begin

These are years where:

  • Your income may be lower
  • You have more control over your income
  • You can intentionally choose your tax rate

But those windows don’t last forever.

If you’re in this window now, this is the time to evaluate it.

No pressure. Just a conversation to see if we can help.

What most people don’t see coming

  • Converting too much in one year
  • Ignoring Medicare thresholds
  • Ignoring ACA Premium Tax Credits
  • Treating conversions as “always good”
  • Waiting too long to start
  • Not projecting future taxes

Most of these don’t look like mistakes when you make them.

They show up later.

Common Roth conversion mistakes

Roth conversions don’t just affect your tax return.

They can also impact:

  • Medicare premiums (IRMAA)
  • Affordable Care Act insurance costs
  • Social Security taxation
  • Future tax brackets

For example:

You might think you’re staying within a tax bracket…

but still trigger higher Medicare premiums

Because those calculations use different formulas.

That’s where simple rules break down.

How Roth conversions fit into your retirement plan

Roth conversions don’t stand alone.

They connect to:

  • Your income plan
  • Your tax strategy
  • Your withdrawal strategy
  • Your long-term goals

This is part of your Keep decision:

how much of your money you keep after taxes

And like everything else:

it works best when coordinated—not isolated
