One of the most common responses I hear after discussing Roth IRAs is:
"I'd love to contribute to a Roth IRA, but I make too much money."
In many cases, that's true. The IRS places income limits on who may contribute directly to a Roth IRA. For many physicians, business owners, executives, and other high-income professionals, a direct Roth IRA contribution simply isn't available. For 2026, individuals who are single or filing as head of household may generally make the full annual Roth IRA contribution if their Modified Adjusted Gross Income (MAGI) is below $153,000. The ability to contribute phases out between $153,000 and $168,000, and direct Roth IRA contributions are generally not permitted once MAGI reaches $168,000.
For married couples filing jointly, the full annual contribution is generally available if household MAGI is below $242,000. The contribution phases out between $242,000 and $252,000, and direct Roth IRA contributions are generally not permitted once MAGI reaches $252,000.
For 2026, the maximum IRA contribution is $7,500 for individuals under age 50 and $8,600 for individuals age 50 and older. These are individual limits and apply to the total contributions made to all of your Traditional and Roth IRAs combined, not to each IRA separately.
If your income exceeds those limits, you might assume your opportunity to build Roth assets has come to an end. Fortunately, that isn't always the case.
Understanding the Backdoor Roth IRA
Congress placed income limits on direct Roth IRA contributions. At the same time, many high-income individuals are still permitted to make a nondeductible contribution to a Traditional IRA.
You might be wondering why someone would intentionally make a contribution that isn't tax deductible.
The answer is simple. For many high-income earners, a nondeductible Traditional IRA contribution provides the first step toward building additional Roth assets through a Backdoor Roth IRA.
Rather than stopping with the Traditional IRA, those funds may then be converted to a Roth IRA if appropriate. That process is what has become known as the Backdoor Roth IRA strategy.
Despite its name, the Backdoor Roth IRA isn't a separate type of retirement account or a loophole. It's simply a planning strategy that uses existing tax law.
In many cases, I recommend establishing a new Traditional IRA specifically for the nondeductible contribution. Although an existing Traditional IRA may sometimes be used, I have found that a separate account creates a cleaner recordkeeping trail and helps keep the transaction organized. Once the after-tax contribution has been made, those funds may then be converted to a Roth IRA if appropriate. Before completing the conversion, it's also important to evaluate any existing Traditional, SEP, or SIMPLE IRA balances, since they may affect the tax consequences of the strategy. To properly document the strategy, the nondeductible contribution should also be reported on your tax return to establish your after-tax basis using IRS Form 8606.
While the process itself is relatively straightforward, deciding whether a Backdoor Roth IRA is the right strategy requires a closer look at your overall financial picture.
Why I'm Such a Fan of the Backdoor Roth IRA
If you read my previous article comparing Traditional IRAs and Roth IRAs, you may remember the question I like to ask:
Would you rather receive your tax benefit today or later?
As I explained in that article, there isn't one correct answer. Every person's situation is different. Whenever I speak to groups, I like to ask a simple question.
What is the highest federal marginal income tax rate in U.S. history?
Almost no one gets it right. The answer is 94%. Will tax rates ever return to those levels? None of us can know with certainty. What history does remind us is that tax laws change, and sometimes they change dramatically. Personally, due to our $40 trillion of national debt, I believe our future tax rates could be significantly higher than today. That's one of the reasons I place so much value on helping clients build Roth assets whenever it makes sense.
For many high-income individuals, once direct Roth IRA contributions are no longer available, the Backdoor Roth IRA may provide an opportunity to continue building Roth assets year after year. What makes that exciting isn't simply the annual contribution - It's what those contributions have the potential to become over time. Money invested inside a Roth IRA has the opportunity to compound for decades. If IRS requirements are met, both the contributions and the investment earnings may ultimately be withdrawn generally free from federal income tax. The earlier those dollars begin working, the more time they have the opportunity to grow. Someone in their 30s or 40s who consistently utilizes a Backdoor Roth IRA strategy each year may be giving those assets decades to compound before retirement. That's the power of giving your investments time to compound. I don't believe it's the right strategy for everyone, but I do believe it's one of the most valuable planning opportunities available for many individuals who are no longer eligible to contribute directly to a Roth IRA.
One Important Planning Consideration
One of the most important factors to evaluate before implementing a Backdoor Roth IRA is whether you already own Traditional IRA, SEP IRA, or SIMPLE IRA assets. The reason is something known as the pro-rata rule. Many people assume they can make an after-tax contribution to a Traditional IRA, convert those funds to a Roth IRA, and owe little or no tax on the conversion. That isn't always the case. If you already own pre-tax IRA assets, the IRS generally requires all of your Traditional, SEP, and SIMPLE IRAs to be viewed together when determining the taxable portion of a Roth conversion. Rather than allowing you to convert only your after-tax contribution, the IRS generally treats the conversion as containing a proportional mix of both pre-tax and after-tax dollars. That can create an unexpected tax bill if it isn't evaluated beforehand.
A Simple Example
Imagine two physicians each contribute $7,500 of after-tax dollars to a Traditional IRA and both intend to complete a Backdoor Roth IRA. The first physician doesn't own any other Traditional, SEP, or SIMPLE IRA assets. The second physician has $300,000 in pre-tax Traditional IRA assets from previous years. Although they're following the same process, the tax consequences can be very different because of the pro-rata rule. The IRS doesn't look at only the new $7,500 contribution. Instead, it generally looks at all of your Traditional, SEP, and SIMPLE IRA balances combined.
Suppose, for the purposes of this example, the second physician has:
- $300,000 of pre-tax IRA assets
- $7,500 of after-tax IRA assets
That means in this simplified example, only about 2.4% of the combined IRA balance represents after-tax dollars, while approximately 97.6% represents pre-tax dollars. As a result, when the physician converts $7,500 to a Roth IRA, only about 2.4% of that conversion would generally be treated as after-tax. The remaining portion would generally be taxable. That's why two individuals can complete what appears to be the exact same transaction and experience very different tax results. That's one of the reasons I encourage clients to evaluate the strategy before implementing it.
Who Should Consider a Backdoor Roth IRA?
Although every situation is different, I believe this strategy deserves consideration for many individuals who:
- Earn too much to contribute directly to a Roth IRA.
- Are already maximizing employer-sponsored retirement plans.
- Want to continue building Roth assets throughout their working years.
- Value the flexibility that generally tax-free qualified withdrawals may provide in retirement if IRS requirements are met.
- Are looking to build greater tax diversification as part of their retirement plan.
Final Thoughts
One of the things I enjoy most about retirement planning is helping clients discover opportunities they didn't know were available. For many high-income earners, the Backdoor Roth IRA is one of those opportunities. When implemented under the right circumstances, it can become another valuable tool for building tax-diversified retirement income over time. If your income has kept you from contributing directly to a Roth IRA, don't assume the conversation ends there. A Backdoor Roth IRA may be another opportunity worth exploring as part of your overall retirement plan.
