What Is a Roth Conversion?
A Roth conversion involves moving money from a pre-tax retirement account (like a Traditional IRA or 401(k)) into a Roth IRA. You’ll pay income taxes on the converted amount in the year you do the conversion, but from that point forward, the money grows tax-free — and qualified withdrawals in retirement are tax-free as well.
5 Reasons to Consider a Roth Conversion
1. Tax-Free Growth for Life
Once in a Roth IRA, any investment growth in the account is tax-free. And when you take qualified withdrawals in retirement, you pay zero income taxes on the gains. However, please bear in mind that accounts could fail to grow in the future depending on the investments.
2. Tax Diversification in Retirement
Having both taxable and tax-free retirement accounts allows you to manage your tax bracket more effectively in retirement, helping you avoid large spikes in taxable income and giving you more control over your withdrawals.
3. You Expect Higher Taxes Later
If you believe your income (or tax rates in general) will be higher in the future, converting now at a lower rate could save you thousands in lifetime taxes.
4. No Required Minimum Distributions (RMDs)
Traditional IRAs require you to start taking distributions at age 73, even if you don’t need the money. Roth IRAs, however, don’t have RMDs during your lifetime, giving you greater control over your retirement cash flow.
5. Leave a Tax-Free Legacy
Roth IRAs can be passed on to beneficiaries tax-free, potentially providing a powerful estate planning advantage.
This can result in a significantly greater net inheritance compared to pre-tax accounts.
What’s more, many beneficiaries inherit IRAs during their own peak earning years — typically in their 40s, 50s, or 60s. If they inherit a traditional IRA, they’re required to begin withdrawing that money (often over a 10-year period), which can push them into a higher tax bracket and increase their total tax burden.
By converting to a Roth during your lifetime, you pay the taxes now — potentially at a lower rate — and relieve your heirs of that burden later. That means they keep more of what you leave behind.
What to Watch Out For: Potential Drawbacks of a Roth Conversion
While the long-term benefits can be compelling, it’s essential to be aware of the short-term costs and consequences of a Roth conversion.
1. Higher Tax Bill in the Year of Conversion
The converted amount is taxed as ordinary income. This could push you into a higher tax bracket unless you plan your conversions in smaller amounts over several years.
2. IRMAA (Medicare Surcharge)
If you’re on Medicare or will be within the next two years, a Roth conversion could increase your MAGI (Modified Adjusted Gross Income) — which may trigger IRMAA surcharges on Medicare Part B and D premiums. These surcharges can add hundreds or even thousands of dollars per year in unexpected costs.
Important: IRMAA is based on your tax return from two years ago. A conversion this year (2025) could impact your Medicare premiums in 2027.
3. Paying the Tax Bill
Ideally, you should pay the taxes on a Roth conversion with money outside your retirement accounts. Using the converted funds to pay the tax could reduce the benefit — and possibly trigger a penalty if you’re under age 59½.
4. Five-Year Rule
Each Roth conversion has its own 5-year clock. Withdrawing converted amounts before five years (or before age 59½) could lead to early withdrawal penalties, even though you've already paid tax on the conversion.
When Might a Roth Conversion Make Sense?
- You’re in a low-income year (e.g., early retirement, gap years between jobs, etc.)
- You have room in a lower tax bracket and want to take advantage of it
- You’re planning around RMDs or estate planning
- You’re concerned about rising tax rates in the future
Final Thoughts
A Roth conversion can be a smart move — but only when done strategically. It’s not just about paying taxes now to avoid them later. It’s about understanding how much to convert, when to convert, and how it fits into your overall financial plan.
