When retirees hear about Roth conversions, the reaction is usually mixed. On the one hand, the idea of paying taxes now to secure tax-free income later makes sense. On the other, the thought of triggering a potentially large tax bill in retirement feels like stepping on a financial landmine.
So, should you do a Roth conversion in retirement? The answer depends on your income, your goals, and your long-term tax picture. A Roth conversion can be a powerful tool, but it’s not a one-size-fits-all solution. Let’s explore how conversions work, when they make sense, and when you might want to avoid them.
What Is a Roth Conversion?
A Roth conversion is when you move money from a traditional IRA or 401(k) into a Roth IRA. The catch? Any pre-tax dollars you convert are added to your taxable income for the year. You’ll ow income tax on the amount you convert. But once it’s in the Roth the money grows tax-free and future qualified withdrawals are tax-free as well.
In other words, you’re trading a tax bill today for the promise of tax-free income tomorrow.
Why Consider a Roth Conversion in Retirement?
Here are some of the most common reasons retirees explore this option:
- Reducing future Required Minimum Distributions (RMDs): Traditional accounts force you to take taxable withdrawals starting at age 73. Converting some funds to a Roth now reduces the balance subject to RMDs later.
- Tax-free income flexibility: Once you’ve met the rules (59½ and the five-year rule), Roth withdrawals don’t count as taxable income. That flexibility can help you manage your tax bracket in retirement.
- Legacy planning: Heirs who inherit a Roth IRA generally receive tax-free withdrawals. Converting during your lifetime can reduce their future tax burden.
- Potentially higher tax rates ahead: If you believe your tax rate will rise in the future—either because of changes in law or changes in your income—a conversion lets you pay taxes now at what may be a lower rate.
- Taking advantage of a market drop: Converting when the market drops allows you to take advantage of your lower balance. You’ll be able to convert a larger portion of your balance for the same tax hit, and then let it rebound in a Roth IRA.
The Tax Trade-Off
Of course, the big drawback to a Roth conversion is the immediate tax bill. Converting $100,000 from a traditional IRA, for example, could push you into a higher bracket for the year. It could also trigger other consequences:
- Higher Medicare premiums: Known as IRMAA, these surcharges apply when your income crosses certain thresholds. A conversion could tip you into higher premiums for Part B and Part D.
- More of your Social Security becoming taxable: Because conversions increase your provisional income, they can make a larger portion of your Social Security benefits taxable.
- Impact on tax credits or deductions: Some retirees benefit from credits that are phased out at higher income levels. A conversion could reduce or eliminate those.
That’s why timing and careful calculation are so important.
When a Roth Conversion Makes Sense
A Roth conversion can be a smart move in retirement under certain circumstances:
- Low-income years: If you have a few years between retiring and starting Social Security or RMDs, your taxable income may be lower. That’s an ideal window to convert at a reduced tax rate.
- Managing Tax Brackets: If you’re currently in your lowest expected tax bracket, converting just enough to “fill up” the rest of that bracket can make sense and prevent going into a higher bracket later.
- Desire to leave tax-free assets to heirs: Converting now can spare your children or grandchildren from paying taxes on inherited IRA withdrawals later.
- Confidence in paying the tax bill: A conversion is easier to stomach if you have funds outside your retirement accounts to cover the taxes. If you don’t it may still be a good idea but paying taxes with IRA money reduces the long-term benefit.
When to Think Twice
There are also times when a conversion may not be in your best interest:
- Already high income: If you’re already in a high bracket, adding more income from a conversion could mean paying unnecessarily steep taxes.
- Close to starting Medicare: If you’re on the edge of an IRMAA threshold, a conversion could increase your premiums for at least one year. That doesn’t necessarily mean you shouldn’t do it, but it’s a factor to consider.
- Short time horizon: If you need the money soon, there may not be enough time for the tax-free growth to make up for the immediate tax hit.
An Example
Let’s say you’re 67, recently retired, single, and haven’t claimed Social Security yet. Your only income is $25,000 a year from part-time consulting. You have $500,000 in a traditional IRA.
This year, you decide to convert $50,000 to a Roth. That raises your taxable income but keeps you within the 22% bracket. You’ll owe about $11,000 in taxes, but now you’ve reduced your future RMDs and set aside a pool of money that can be withdrawn tax-free. Over time, this can reduce your lifetime tax bill and leave your heirs a more tax-efficient inheritance.
Should I do Roth Conversions in Retirement?
A Roth conversion in retirement can be a valuable strategy—but it’s not a decision to make lightly. It requires weighing today’s tax cost against tomorrow’s potential savings. For some retirees, conversions are an effective way to reduce future RMDs, gain more flexibility, and improve estate planning. For others, the upfront tax hit may outweigh the benefits.
The best approach is to evaluate conversions as part of your overall retirement income plan. Consider your tax bracket now versus later, your healthcare costs, your Social Security timing, and your goals for leaving a legacy. With careful planning, a Roth conversion can be more than just a tax maneuver—it can be a key part of ensuring your retirement income works the way you want it to.
