How Backdoor Roth Strategies Can Help You Build Tax-Free Wealth

Jul 14 2025 | Back to Blog List

Building a successful career shouldn’t disqualify you from contributing to a Roth IRA, one of the most powerful retirement tools available, but that’s the reality for many professionals, executives, and business owners.

Income thresholds phase out direct contributions to these accounts, leaving high earners locked out of the tax-free growth these accounts provide. But with the right planning, there are ways to “open” those doors—legally, strategically, and to your long-term benefit.

Two strategies, the backdoor Roth IRA contribution and the mega backdoor Roth contribution, can help high earners move their funds into these specialized accounts. And these approaches aren’t gimmicks or legally gray—they’re well-established, IRS-recognized strategies that can help you build lasting wealth and greater flexibility in retirement.

Here’s what you need to know about backdoor and mega backdoor Roth contributions, and why they might deserve a place in your wealth planning efforts.

Why Backdoor Roth Tactics Matter for High Earners

Unlike traditional retirement accounts, Roth IRAs and Roth 401(k)s grow tax-free and offer tax-free withdrawals in retirement after age 59½ and meeting the five-year rule (more on that in a bit). That means no surprise tax bills on future growth—even if your investments grow substantially over the coming decades.

However, high-income earners face IRS income limits that block them from contributing to Roth IRAs directly. For 2025, single filers with a modified adjusted gross income (MAGI) at $165,000 and over (or $246,000 and over for married filing jointly) can’t contribute directly to a Roth IRA at all. These thresholds adjust for inflation, but they effectively shut out many successful professionals, executives, and business owners from the benefits of Roth savings.

This is where backdoor strategies come into play. High-income earners may be able to take advantage of either IRA contributions paired with Roth conversions, or 401(k) plan features that allow after-tax contributions and Roth conversions. Both routes offer the ability to bypass these income restrictions legally and efficiently and contribute to these tax-free accounts.

For high-income professionals, Roth conversions also solve a few common challenges:

• No Required Minimum Distributions (RMDs): Unlike Traditional IRAs, Roth IRAs don’t force you to take annual distributions once you reach a certain age (age 73 for those born in 1959 or earlier, or age 75 for those born in 1960 or later). Your money can stay invested, compounding tax-free until you actually need it, or you can leave it to your heirs.
• A Hedge Against Rising Taxes: Many investors anticipate that tax rates will increase over time. Roth assets can help you control your taxable income, soften the impact of RMDs from pre-tax accounts, and give you more flexibility to manage your tax profile in retirement.
• Tax Diversification: Having a mix of pre-tax, taxable, and Roth accounts gives you more flexibility in retirement. By diversifying your tax exposure, you can better adapt to policy changes, manage cash flow needs, and create a withdrawal strategy that supports your lifestyle with minimal tax impact.
• Estate Planning Benefits: Roth IRAs can generally pass to heirs as tax-free assets, although they are subject to the 10-year rule for non-eligible designated beneficiaries.

For those whose success excludes them from making direct Roth contributions, backdoor Roth IRA and mega backdoor Roth 401(k) strategies give you the opportunity to build this valuable tax-free bucket.

What Is a Backdoor Roth IRA Contribution and How Does It Work?

The backdoor Roth IRA contribution is the more common of the two strategies. It’s not a special account, but a process—a legal workaround for the IRS income limits on Roth contributions that’s available to everyone with enough money to save.

The 3 Steps of a Backdoor Roth IRA Contribution

• Contribute to a Traditional IRA: High earners make an after-tax (non-deductible) contribution to a Traditional IRA. In 2025, you can contribute up to $7,000 per person ($8,000 if age 50 or older).
• Convert to a Roth IRA: You then convert that contribution to a Roth IRA. The conversion is generally tax-free as long as the contribution was made with after-tax dollars and you don’t hold other pre-tax IRA balances, due to the pro rata rule (more on that later).
• Report and Enjoy the Benefits: You'll receive Forms 1099-R and 5498 from your custodian and need to file Form 8606 with your tax return to report the non-deductible contribution and Roth conversion. Your adviser or tax preparer can walk you through this.

While the backdoor Roth IRA is fairly straightforward, there are nuances to keep in mind. The IRS’s pro rata rule, for example, can complicate conversions if you have existing pre-tax balances in any Traditional, SEP, or SIMPLE IRAs—the taxable portion of your conversion may be higher than expected. Many investors work with their adviser to roll these pre-tax IRA dollars into an eligible employer retirement plan (like a 401(k)) before executing a Roth conversion—we can help you navigate all of these potential stumbling blocks.

For many of our high-earning clients, the backdoor Roth contribution is an annual ritual, much like tax loss harvesting—a reliable way to potentially build thousands of dollars in Roth savings each year, regardless of income limits.

The Mega Backdoor Roth Contribution: Turbocharging Your Roth Savings

If the backdoor Roth IRA contribution is a yearly tune-up, the mega backdoor Roth strategy is a turbocharger. This process is only available to those with employer-sponsored 401(k) plans allowing after-tax contributions and in-plan Roth conversions or in-service distributions. If that’s you, it can allow for tens of thousands in additional Roth savings each year, depending on plan rules and eligibility.

How a Mega Backdoor Roth Strategy Works:

• After-Tax 401(k) Contributions: Once you’ve maxed out your regular 401(k) deferrals ($23,500 in 2025, plus catch-ups if over 50), you may be able to make additional after-tax contributions to your 401(k), if your plan allows. The 2025 IRS Defined Contribution Plan maximum of $70,000 (or even higher with catch-up contributions for those over 50) includes your salary deferrals, employer contributions, and after-tax contributions. Note: There may be additional plan testing requirements, and in some cases your specific plan may limit total plan contributions to less than the IRS limit.
• Convert to Roth (In-Plan or via Rollover): Those after-tax contributions are then converted into Roth status. Some plans permit in-service distributions to roll those funds into a Roth IRA while still working. If a plan doesn’t allow the latter option, an in-plan conversion to a Roth 401(k) is typically available.

The “mega” label is no exaggeration. Depending on your plan’s rules and employer contributions, you may be able to shift $30,000+ of income each year into Roth dollars. It may make the most sense for those who are already maxing out traditional retirement vehicles and still have capacity to save.

What to Know Before Using Backdoor Roth Strategies

These strategies can be highly effective, but they’re certainly not something to “set and forget.” Each strategy comes with rules, timing considerations, and potential tax implications that require careful planning and synchronization. As a fiduciary and an independent RIA, we can guide you through every step to help minimize your tax exposure and stay aligned with your long-term goals.

Here are a few key factors we’ll be watching:

• IRS Rules and Reporting: Roth conversions trigger specific tax forms and reporting requirements. A backdoor Roth IRA contribution requires filing Form 8606 to document your non-deductible IRA contribution and Roth conversion so you’re not taxed twice on those dollars. Roth conversions often generate Forms 1099-R and 5498, which detail the movement of funds. Mistakes or omissions can confuse the IRS and create unnecessary headaches, so accurate reporting is key.
• Five-Year Clock: Each Roth conversion starts its own five-year clock before the converted principal can be withdrawn without penalty if you’re under age 59½. This is separate from the five-year rule that applies to earnings in a Roth IRA. It’s best to consult your adviser or a tax professional to be aware of the implications of withdrawing funds after a Roth conversion.
• Timing the Conversion: With either backdoor Roth strategy, timing matters. For a backdoor Roth IRA contribution, consider subsequently converting your after-tax IRA contribution before investment gains occur to help avoid an unplanned tax liability. With the mega backdoor Roth strategy, some employer retirement plans allow for automated in-plan Roth conversions, helping to limit taxable growth. Alternatively, you may decide to manually complete Roth conversions or in-service rollovers periodically, but be aware that there may be taxable growth in the account.
