What is a Roth Conversion and How is it Done?

A Smart Strategy for Managing Future Taxes in Retirement

When it comes to retirement planning, one of the most talked-about strategies is the Roth conversion, and for good reason. A Roth conversion can help you take greater control of your tax picture, diversify your retirement income sources, and potentially reduce future tax burdens.

But what exactly is a Roth conversion, and how do you know if it’s right for you? In this post, we break down the essentials of how a Roth conversion works, when it might make sense, and how to navigate the process.

Understanding Roth IRAs and Traditional IRAs

To understand Roth conversions, it helps to know the difference between a Traditional IRA and a Roth IRA.

  • A Traditional IRA allows you to contribute pre-tax dollars (if you’re eligible), and the investments grow tax-deferred. You’ll pay ordinary income tax when you withdraw the funds in retirement.
  • A Roth IRA, on the other hand, is funded with after-tax dollars. Qualified withdrawals in retirement are entirely tax-free, and Roth IRAs are not subject to Required Minimum Distributions (RMDs) during the owner’s lifetime.

A Roth conversion is the process of moving assets from a Traditional IRA (or other eligible retirement account) into a Roth IRA. The catch? You’ll owe income taxes on the amount you convert, but then those assets can grow tax-free from that point forward.

Why Consider a Roth Conversion?

There are a number of situations where a Roth conversion may be particularly advantageous:

  • You expect to be in a higher tax bracket in retirement.
  • You have a long investment time horizon and want tax-free growth.
  • You want to reduce the size of your traditional IRA to lower future RMDs.
  • You’re planning for heirs and wish to pass on tax-free assets.
  • You’ve had a drop in income (due to a career change, early retirement, or business loss) and want to “fill up” a lower tax bracket.

A Roth conversion may not be right for everyone, but it can offer significant benefits under the right circumstances. However, it’s important to keep in mind that timing is everything. Converting too much in a single year could push you into a higher tax bracket, increase your Medicare premiums, or affect other tax-related thresholds.

Benefit #1: Tax-Free Growth for the Future

Once your money is inside a Roth IRA, it grows tax-free and can be withdrawn tax-free in retirement, as long as the account has been open for at least five years and you are at least 59½ years old. This means you won’t owe any income taxes on the investment gains, interest, or dividends when you withdraw them later in life. Over a 10-, 20-, or 30-year horizon, that tax-free growth can significantly boost the value of your retirement savings.

For investors who expect their assets to grow substantially or want to leave a tax-free legacy to heirs, a Roth IRA provides a powerful long-term planning tool. Because distributions from Roth IRAs are not taxed, they can also serve as a reliable reserve for significant future expenses, such as healthcare or travel, without triggering a spike in taxable income.

Benefit #2: Flexibility in Retirement Income Planning

Unlike traditional IRAs and 401(k)s, Roth IRAs are not subject to Required Minimum Distributions (RMDs) during the original account owner’s lifetime. This gives you greater flexibility to control when and how you draw income in retirement. For retirees who want to manage their taxable income—for example, to stay in a lower tax bracket, avoid higher Medicare premiums, or minimize taxation on Social Security income—this can be a critical advantage.

You can choose to withdraw from the Roth IRA only when it best serves your financial goals, or not at all. For married couples or those considering their spouse’s future tax situation, holding assets in a Roth account can also help smooth out income and reduce the surviving spouse’s tax burden.

Benefit #3: Strategic Use of Lower Tax Brackets

Roth conversions allow you to pay taxes on your retirement savings now—ideally at a lower rate—rather than later when rates could be higher. This strategy is particularly beneficial during years when your income is temporarily reduced, such as during early retirement, a career break, or following business losses.

For example, if you typically fall into the 24% tax bracket but expect to drop into the 12% or 22% bracket for a couple of years, converting a portion of your traditional IRA to a Roth IRA during those lower-income years can lock in favorable tax treatment. By “filling up” the lower brackets with conversion income, you can avoid paying higher rates in the future, when RMDs or other income sources may push you into a higher tax tier.

How a Roth Conversion is Done

The conversion process can be fairly straightforward, but it’s important to plan carefully. Here are the basic steps:

  1. Decide How Much to Convert – You don’t have to convert your entire account—you can choose a partial amount. This allows you to spread the tax liability over several years if needed.
  2. Understand the Tax Impact – The amount converted is added to your taxable income for the year. This could result in a higher tax bill, so it’s wise to consult a financial advisor or tax professional to project the outcome.
  3. Initiate the Transfer – Work with your IRA custodian or financial institution to transfer the selected funds from your Traditional IRA (or an eligible account, such as a 401(k)) into a Roth IRA. This can be done as a direct transfer or rollover.
  4. Pay the Taxes – Ideally, you’ll pay the taxes owed from sources outside the retirement account to preserve the full value of the converted assets. Paying taxes from the IRA itself can reduce the long-term benefit of the conversion.
  5. Start the Five-Year Clock – Each conversion has its own five-year waiting period before earnings can be withdrawn tax-free. If you’re under age 59½, this rule is especially important to avoid early withdrawal penalties.

Final Thoughts: A Proactive Approach to Retirement Taxes

A Roth conversion is not just a tax move—it’s a strategic decision that can significantly influence your financial future. When done thoughtfully, it allows you to shift some of your retirement savings into a more flexible, tax-advantaged vehicle, giving you more control and peace of mind.
