Should I Do A ROTH IRA Conversion?

A Roth IRA conversion can be a powerful strategy—but only in the right window.

If you’re within 5–10 years of retirement, the decision isn’t just about taxes today. It’s about how your income, Social Security, and required distributions will interact over time.

Many people miss this window entirely.

Short Answer

A Roth IRA conversion may make sense if you expect higher future tax rates, want tax-free retirement income, or aim to reduce required minimum distributions.

The real decision depends on:

  • Your current and future tax brackets

  • Timing relative to Social Security and RMDs

  • Medicare premium thresholds (IRMAA)

  • California state taxes

When a Roth Conversion Can Make Sense

Roth conversions are often most effective during low-income years, especially in the transition between working years and full retirement income.

They may be a strong fit if you:

  • Expect higher taxes later due to RMDs or Social Security

  • Are retired but haven’t started Social Security yet

  • Want more flexibility in how you draw income later

  • Are looking to reduce future taxable income

  • Want to pass assets more efficiently to heirs

When a Roth Conversion May Not Make Sense

Not every year is a good year to convert.

It may not be appropriate if:

  • You’re already in a high tax bracket

  • You need the IRA funds in the near term

  • You’d need to sell investments to pay the tax

  • It would significantly increase Medicare premiums (IRMAA)

  • It would negatively impact ACA subsidies or other benefits

How Roth Conversions Are Taxed in California

Roth conversions are taxed as ordinary income at both the federal and state level.

There is no preferential treatment in California, which makes timing and partial conversions across multiple years especially important.

Common Roth Conversion Mistakes

Where most people go wrong isn’t the idea—it’s the execution.

  • Converting too much in a single year

  • Ignoring Medicare premium thresholds

  • Increasing taxation of Social Security unintentionally

  • Not coordinating conversions with withdrawal strategy

  • Treating it as a one-time decision instead of a multi-year strategy

Where This Fits in Your Retirement Plan (this is the missing piece)

A Roth conversion is not a standalone strategy.

It connects directly to:

  • How your retirement income is taxed

  • When you start Social Security

  • How you draw from your accounts

  • How your portfolio supports your income over time

If you’re thinking about conversions, it usually means you’re really trying to answer a bigger question:

“How do I structure my income in retirement so it’s reliable and tax-efficient?”
