Retirement often creates a short window where your taxable income looks very different than it will later.
A paycheck may have stopped. You may not have started Social Security yet. A pension might begin later. And required minimum distributions (RMDs) may still be years away.
That gap can create a tax-planning window—a period when you may have more control over taxable income than you will once RMDs start.
Quick Answer
A Roth conversion before RMDs begin can make sense when you expect your future tax rate, future RMDs, or future taxable income to be higher than they are today.
But the better question usually isn’t:
“Should I convert my IRA?”
It’s:
“How much, if any, should I convert this year?”
Because the amount you convert can affect current taxes, future RMDs, Medicare premiums, Social Security taxation, charitable planning, and what your heirs may eventually inherit.
(If you want a structured way to evaluate these moving pieces, George Wealth Management’s Retirement Planning process is designed to coordinate these decisions rather than treating them one at a time.)
1) What Is a Roth Conversion?
A Roth conversion moves assets from a traditional IRA (or another eligible pre-tax retirement account) into a Roth IRA.
- The amount converted is typically included in taxable income in the year of conversion.
- In exchange, future qualified Roth IRA withdrawals may be tax-free.
- Roth IRAs also generally do not have lifetime RMDs for the original owner.
A conversion is essentially:
Paying some tax today in exchange for potentially more tax flexibility later.
Simple concept—complicated decision.
2) Why RMDs Change the Planning Conversation
Once RMDs begin, you may have less control over how much taxable income comes out of traditional retirement accounts each year.
If your traditional IRA grows over time, future RMDs can become large enough to affect multiple areas of your plan, such as:
- Federal income taxes
- Medicare premiums (IRMAA)
- How much of your Social Security is taxable
- Investment income surtaxes
- Charitable giving strategies
- Beneficiary and estate planning decisions
This is why the years before RMDs begin often deserve special attention.
3) The Goal Usually Isn’t to “Eliminate Taxes”
A common trap is focusing only on minimizing taxes this year.
For example, if you recently retired and your income is temporarily low, you might avoid conversions to keep your tax bill down today. That may be reasonable.
But if your IRA continues growing and later produces large RMDs on top of Social Security (and possibly pension income), the long-term tax picture could look very different.
A more helpful framing is:
“How do I manage taxes over my lifetime—not just this April?”
4) Tax Brackets: A Useful Starting Point (Not the Whole Answer)
One common approach is to estimate your taxable income and identify “room” left in your current tax bracket. Then, you evaluate whether converting up to a certain threshold is worth considering.
But tax brackets are only part of the math. A larger conversion may also interact with Medicare premiums, Social Security taxation, and other parts of the plan.
In other words, your tax return can tell you what happened last year—but Roth decisions are about managing what could happen over many years.
5) Medicare Premiums (IRMAA) Can Change the Math
Medicare Part B and Part D premiums can increase when your modified adjusted gross income (MAGI) crosses certain thresholds. These income-related adjustments are commonly known as IRMAA.
Because a Roth conversion increases taxable income, it can also increase Medicare premiums in a later year.
That doesn’t automatically mean “don’t convert.” It means the Medicare cost should be included when you evaluate the tradeoff.

6) Social Security Timing Matters
Depending on your total income, up to 85% of Social Security benefits may be taxable. Adding Roth conversion income can increase the taxable portion of Social Security, raising your effective cost of converting beyond what you’d assume from the marginal bracket alone.
That’s why conversions done before Social Security begins can look very different than conversions done after benefits start.
7) How Will You Pay the Tax?
A practical (and often overlooked) question:
Where will the money come from to pay the conversion tax?
Many retirees prefer—when feasible—to pay conversion taxes using assets outside the IRA (rather than withholding from the converted amount), because that may allow more of the converted assets to remain in the Roth.
However, using taxable accounts to pay the bill may create its own consequences (liquidity needs, capital gains, and portfolio allocation changes). The “best” approach depends on your full plan.
8) Your Time Horizon and Estate Goals Matter
Roth conversions often become more compelling when:
- You have time for the Roth assets to potentially grow
- You don’t need the converted funds for near-term spending
- You want more flexibility later in retirement
- You’re considering the tax impact on heirs
For many families, the conversion question becomes:
“Who should pay the tax—me now, or my heirs later?”
There isn’t one universal answer. It depends on your expected future tax rate, your heirs’ likely tax situation, and what you intend to do with the money.
9) Charitable Giving Can Change the Strategy
If charitable giving is important to you, large traditional IRA balances may not be “bad” in the way people assume.
Qualified charitiable distributions (QCDs) can allow eligible IRA owners to direct certain IRA withdrawals to qualified charities, potentially satisfying part or all of an RMD.
That can influence how aggressively you may (or may not) want to convert to Roth.
10) Roth Conversions Don’t Have to Be All-or-Nothing
A Roth conversion doesn’t have to mean converting everything at once.
Many retirees evaluate partial conversions over multiple years, adjusting as income, tax laws, markets, and spending needs change.
That kind of repeatable decision-making is the idea behind Project Clarity: Discover → Prepare → Decide → Review → Repeat.
Five Questions to Ask Before Converting
- What is my taxable income this year without a conversion?
- What might my taxable income look like once RMDs begin?
- How might a conversion affect Medicare premiums (IRMAA)?
- Where will the money come from to pay the conversion tax?
- Who is most likely to eventually spend this money—me, my spouse, my children, or charity?
These questions won’t produce a one-size-fits-all answer—but they can quickly show whether a conversion deserves deeper analysis.
The Better Question
Instead of asking:
“Should I do a Roth conversion?”
ask:
“How much should I convert, in which years, and what other decisions will that affect?”
That’s where meaningful retirement-tax planning begins.
