The Complete Guide to Roth Conversions in Retirement

If you have money sitting in a traditional IRA or 401(k), every dollar you withdraw in retirement will be taxed as ordinary income. For many retirees, this creates a significant — and often avoidable — tax burden over the course of a 20 or 30-year retirement.

A Roth conversion is one of the most powerful strategies available to reduce that burden. Done correctly, it can save you tens of thousands of dollars in taxes, reduce your required minimum distributions, and leave more money to your heirs. Done incorrectly, it can push you into a higher tax bracket and cost more than it saves.

This guide will walk you through everything you need to know.

A Roth conversion is the process of moving money from a traditional IRA or 401(k) — where contributions were made pre-tax — into a Roth IRA, where future growth and withdrawals are completely tax-free.

When you convert, you pay income tax on the converted amount in the year of conversion. After that, the money grows tax-free and can be withdrawn tax-free in retirement, with no required minimum distributions (RMDs) during your lifetime.

The math is simple: you pay taxes now, at today's rates, to avoid paying taxes later — potentially at higher rates.

Most people think of Roth conversions as a strategy for younger workers. But for retirees, the opportunity is often even greater — and most people miss it entirely.

Here is why: the years between retirement and age 73 (when RMDs begin) represent what financial planners call the Roth conversion window. During this period:

• Your income is often lower than it was during your working years
• You may be in a lower tax bracket than you will be once Social Security and RMDs kick in
• You have time to let the converted funds grow tax-free before you need them
• Converting now reduces the size of your traditional IRA, which reduces future RMDs

This window is temporary. Once Social Security begins and RMDs start, your taxable income rises — and the opportunity to convert at a low rate narrows significantly.

There is no single right answer, but the most common strategy is to convert up to the top of your current tax bracket each year.

For example, if you are in the 22% bracket and have room to convert $40,000 before hitting the 24% bracket, converting $40,000 per year is often optimal. You pay 22% now instead of potentially 24%, 28%, or more later.

The goal is to "fill up" your current bracket without spilling into the next one. This requires careful calculation of your total income for the year, including Social Security, pension income, investment income, and any other sources.

Converting too much in a single year can push you into a higher bracket, trigger additional Medicare premium surcharges (IRMAA), and reduce the net benefit of the conversion. This is why working with an advisor who can model the numbers is so important.

Let us say you have $500,000 in a traditional IRA and you are 65 years old, retired, with $30,000 in annual Social Security income. Your taxable income before any conversion is relatively low.

If you convert $50,000 per year for 10 years, you will have moved $500,000 into a Roth IRA — paying taxes at today's rates on each conversion. Your traditional IRA balance drops to zero, eliminating all future RMDs.

Compare that to doing nothing: at age 73, your RMDs on a $500,000 IRA (which has continued to grow) might be $25,000–$35,000 per year — all taxable, potentially pushing you into a higher bracket, and potentially triggering higher Medicare premiums.

The difference in lifetime tax paid can easily exceed $100,000.

One of the most innovative strategies we offer at The Annuity Guyz is what we call the 24% bonus Roth conversion strategy.

Here is how it works: certain fixed indexed annuities offer a premium bonus — the insurance carrier adds a percentage (often 24%) to your account value when you fund the annuity. When you pair a Roth conversion with one of these products, the bonus effectively offsets a significant portion of the taxes you owe on the conversion.

For example, if you convert $100,000 from a traditional IRA and place it into an FIA with a 24% bonus, the carrier adds $24,000 to your account — bringing your starting balance to $124,000. If you owe $22,000 in taxes on the conversion (at a 22% rate), the bonus more than covers the tax cost.

The result: a tax-free Roth account growing inside an annuity with principal protection, guaranteed interest crediting, and optional lifetime income — with the conversion taxes largely offset by the carrier bonus.

This strategy is not right for everyone, but for the right client, it is extraordinarily powerful.

Converting too much in one year. Pushing yourself into a higher bracket or triggering IRMAA surcharges can wipe out the benefit of the conversion. Spread conversions over multiple years.

Paying conversion taxes from the IRA itself. If you withhold taxes from the converted amount, you are effectively reducing the amount that goes into the Roth — and potentially triggering a 10% early withdrawal penalty if you are under 59½. Pay conversion taxes from a separate taxable account whenever possible.

Ignoring state taxes. Federal tax is only part of the picture. Some states tax Roth conversions; others do not. Factor your state tax rate into the analysis.

Converting without a plan. A Roth conversion strategy should be part of a comprehensive retirement income plan — not a one-time transaction. The optimal amount to convert each year depends on your full financial picture.

Waiting too long. The Roth conversion window is finite. Every year you delay is a year of potential tax-free growth you cannot get back.

A Roth conversion makes the most sense when:

• You expect tax rates to be higher in the future than they are today
• You are in a lower tax bracket now than you will be once RMDs begin
• You have assets outside the IRA to pay the conversion taxes
• You want to reduce or eliminate future RMDs
• You want to leave tax-free assets to your heirs
• You have time for the converted funds to grow before you need them

It makes less sense when you are already in a high tax bracket, when you will need the money soon, or when you do not have outside funds to pay the taxes.

The single most important thing you can do before executing a Roth conversion is to model the numbers carefully. This means projecting your income over the next 10–20 years, estimating future RMDs, comparing the tax cost of converting now versus paying taxes on distributions later, and factoring in Social Security taxation and Medicare premiums.

This is exactly what we do for every client — at no charge. Our independent advisors will run a full Roth conversion analysis for your specific situation and show you the projected lifetime tax savings.

If you have a traditional IRA or 401(k) and you are within 10 years of retirement — or already retired — a Roth conversion analysis is one of the most valuable conversations you can have.
