The Backdoor Roth IRA is a strategy that enables high-income earners to make Roth IRA contributions indirectly when their income exceeds the limits. Why do they care? High earners benefit from high cash savings and a Roth IRA allows a greater contribution towards retirement. Funds in a Roth IRA grow tax-deferred and may be eligible for tax-free distributions in retirement. A Roth IRA can be an effective tax strategy for managing tax brackets in retirement and a legacy planning tool. So how can you benefit from this strategy anyways? Insert -> the Backdoor Roth IRA strategy.
What is the Backdoor Roth IRA?
The Backdoor Roth IRA is a tax strategy that helps high-income earners contribute to a Roth IRA when they’re over the income limits (in 2025, $165,000 for single filers and $246,000 for married couples) by contributing to a traditional IRA and then converting it to a Roth IRA.
First, you make an IRA contribution (up to $7,000 in 2025 for those under 50 years old and $8,000 for those over 50 years old) by April 15th 2026. Then, you can convert this IRA contribution to a Roth IRA. Over time, the Roth IRA compounds and becomes a valuable addition to your retirement savings.
Who Should Consider a Backdoor Roth IRA?
If you are:
- Above the income threshold for a Roth IRA contribution
- Have extra cash during the year and want to save towards retirement
- Are willing to take the steps to set yourself up for a successful Backdoor Roth strategy
When a Backdoor Roth Makes Sense
At SeedSafe Financial, we work with tech professionals who want to get out of the game by their 50s. The Backdoor Roth strategy can be a great way to increase retirement savings.
Many of our tech clients have excess cash from IPOs or large amounts of RSUs – their taxable investments often dwarf retirement savings. This strategy reduces the taxable impact of investing while they are in higher tax brackets.
We also use this for clients who want to leave money to their children when they pass. At this time, a Roth IRA can be passed down to your children with minimal tax impact. For more advanced estate planning, a Roth IRA with a Trust beneficiary can be helpful. Trusts that hold IRAs and Roth IRAs must take distributions on a reduced timeline than if left to children. The Roth IRA reduces the tax impact of the required distributions while still maintaining control over when the kids get the money.

Understanding the Tax Implications
Here comes the tricky part – because there is always a catch when the IRS allows you to do something like this. The Pro-Rata rule.
What is the Pro-Rate Rule?
The Pro-Rata rule in Roth IRA conversions is an additional wrinkle to consider. If you have pre-tax IRA money and non-deductible contributions in one account, the conversion will be partially taxable. An example of pre-tax IRA money is if you rolled a past 401(k) into your IRA.
Why does this happen? You are making a ‘non-deductible’ IRA contribution. A non-deductible IRA contribution means you are over the income limits to be able to deduct this amount on your tax return. So you are making a contribution ‘post-tax’. When you make a ‘post-tax’ contribution, it has a cost basis similar to when you purchase taxable investments. This cost basis in the IRA is not taxable in a conversion. However, anything pre-tax is.
Let’s look at an example: Dave rolled his 401(k) from a past employer to a Traditional IRA in the amount of $500,000. A few years later, Dave decides to start making an annual non-deductible IRA contribution. He forgets to convert it for a few years and now his Traditional IRA is at $600,000 in total with $21,000 in basis from non-deductible IRA contributions. If he decides to convert the $21,000 now, the IRS will tax part of it as income.
($600.000 – $21,000) / $600,000 = 96.5%
96.5% of the $21,000 = $20,265 taxable income in the year of conversion
That was not what we wanted to happen from a tax efficiency standpoint.
So how do you fix this issue? If you are still employed, we often suggest rolling the pre-tax amount back into your 401(k). Then, with just the $21,000 in your Traditional IRA, the result will be very little taxation at conversion.

Common Mistakes to Avoid
Based on the above conversation, there are certainly a few mistakes you can easily make:
- Having a mix of pre-tax and non-deductible funds in your Traditional IRA account
- Forgetting to file the Form 8606 when you make the conversion (to track your non-deductible contributions and basis)
- Doing the conversions too quickly and running into the IRS substance test. Aka, if it looks like a Roth IRA contribution and smells like a Roth IRA contribution, it is.
- Not tracking your Traditional IRA basis on an ongoing basis with your tax return
Backdoor Roth IRA vs. Mega Backdoor Roth
Is there an easier or better way to do this? Many of our big tech clients at Google, Amazon, Apple, Meta, Microsoft and their portfolio companies have the option of an ‘After-Tax 401(k)’. This is included in their 401(k) company benefits and will show up in the contributions area for the plan.
The After-Tax 401(k) allows you to make a Mega Backdoor Roth Contribution! We detail out this strategy and the benefits on our blog post Is a Mega Backdoor Roth Strategy Worth It? The Mega Backdoor Roth is a Backdoor Roth on steroids – a higher contribution amount and less complication with the pro-rata rules.
Summary FAQs About the Backdoor Roth IRA
- Is the Backdoor Roth IRA still legal in 2025?
Yes. The Backdoor Roth IRA remains legal and IRS-approved in 2025. No current legislation has eliminated this strategy for high-income earners.
- Who should use a Backdoor Roth IRA?
It’s best for high-income earners who exceed Roth IRA income limits ($165,000 single / $246,000 joint in 2025) but want tax-free retirement growth.
- What is the Pro-Rata Rule?
If you hold both pre-tax and after-tax IRA funds, the IRS taxes conversions proportionally. Rolling pre-tax funds into a 401(k) can help avoid extra taxes.
- What’s the difference between a Backdoor Roth and a Mega Backdoor Roth?
A Backdoor Roth uses an IRA; a Mega Backdoor Roth uses after-tax 401(k) contributions to convert much larger amounts – up to roughly $70,000 per year. This limit includes your employee contribution (up to $23,500 in 2025) + employer match + after-tax 401(k) = $70,000 max.
- Can I do a Backdoor Roth every year?
Yes. As long as conversions are allowed, you can complete a Backdoor Roth annually and track it with Form 8606.
