What Is a Backdoor Roth IRA?
Definition: Backdoor Roth IRA
A backdoor Roth IRA is a strategy that allows higher income earners to fund a Roth IRA even when their income exceeds the limit for direct contributions. With this approach, an individual first contributes to a Traditional IRA and then converts those funds to a Roth IRA. While the IRS sets income limits for direct Roth IRA contributions, it does not impose income limits on Roth conversions.
As a result, a backdoor Roth can provide a path for individuals who are otherwise ineligible to contribute directly to a Roth IRA to still move retirement savings into a Roth account.
What is a Roth Conversion?
A Roth conversion is the process of moving funds from a Traditional IRA or other pre-tax retirement account into a Roth IRA. When the conversion occurs, the amount converted may be subject to income taxes, but future investment growth and qualified withdrawals from the Roth IRA can be tax-free.
Benefits of Backdoor Roth IRA
Tax-Free Growth
Roth IRAs allow investments to grow tax-free within the account. If withdrawals meet IRS qualified distribution rules, funds can be taken tax-free in retirement.
No Required Minimum Distributions
Roth IRAs are not subject to required minimum distributions during the lifetime of the original account owner.
Tax Diversification
A backdoor Roth IRA can improve tax diversification by helping investors build a mix of pre-tax and after-tax retirement assets. That can provide more flexibility when planning future withdrawals in retirement.
How a Backdoor Roth IRA Works
The backdoor Roth IRA strategy typically involves the following process:
- Contribute to a Traditional IRA
- Ensure the contribution stays within annual IRA contribution limits
- Convert the Traditional IRA funds to a Roth IRA
This strategy allows individuals whose income exceeds Roth IRA contribution limits to still move retirement savings into a Roth IRA. Although direct Roth contributions are restricted by income, Roth conversions are not subject to the same limits.
Backdoor Roth IRA Tax Implications
Before completing a backdoor Roth IRA strategy, it is important to review your existing IRA balances to determine whether the IRS pro-rata rule could affect the tax treatment of the conversion.
A Roth conversion may create taxable income depending on the type of contribution made and whether you hold other IRA balances. If the Traditional IRA contribution was non-deductible and little or no earnings accrued before the conversion, the tax impact may be limited. However, if you have other pre-tax IRA balances, a portion of the conversion may be taxable under IRS pro-rata rules.
Because of this, many individuals review their overall IRA balances before using a backdoor Roth strategy. Consulting a qualified tax professional can help clarify the potential tax consequences of the conversion.
Who Is Eligible for a Backdoor Roth IRA?
Anyone with pre-tax retirement savings is eligible to convert those savings to a Roth IRA, even if they do not have earned income. However, this strategy is most used by individuals whose income exceeds the limits for direct Roth IRA contributions. Eligibility for direct Roth IRA contributions is based on Modified Adjusted Gross Income, or MAGI.
What Is MAGI?
Modified Adjusted Gross Income (MAGI) is a measure of income used by the IRS to determine eligibility for certain tax benefits. It starts with Adjusted Gross Income (AGI) and adds back specific deductions.
For 2026, the MAGI phase-out ranges for Roth IRA eligibility are:
Single individuals: $153,000 to $168,000
Married filing jointly: $242,000 to $252,000
Married filing separately: $0 to $10,000
Once income exceeds these ranges, Roth IRA contributions may no longer be permitted.
Roth IRA Contribution Limits for 2026
Even when using a backdoor Roth strategy, standard IRA contribution limits still apply.
IRA contribution limit: $7,500
Catch-up contribution (age 50+): $1,100
Individuals under age 50 may contribute up to $7,500 to an IRA during 2026. Individuals age 50 or older may contribute up to $8,600.

Is There a Difference Between a Backdoor Roth and a Mega Backdoor Roth?
Yes. Both strategies move money into Roth accounts but use different retirement plans. Both strategies are designed to help individuals increase their Roth retirement savings, particularly when income limits or standard contribution limits would otherwise restrict Roth contributions.
Backdoor Roth IRA
A backdoor Roth IRA uses a Traditional IRA contribution followed by a Roth conversion.
Mega Backdoor Roth
A mega backdoor Roth is a different strategy that uses an employer-sponsored retirement plan, such as a 401(k).
Instead of contributing through an IRA, the strategy involves making after-tax contributions to a 401(k) and then converting or rolling those funds into a Roth account.
Because 401(k) plans have much higher contribution limits, the mega backdoor Roth strategy can allow significantly larger amounts to move into Roth accounts each year.
However, not all employer plans allow this strategy. The 401(k) plan must permit after-tax contributions and either in-plan conversions or in-service withdrawals.
How a Backdoor Roth IRA May Fit into a Retirement Strategy
A backdoor Roth IRA can be a useful strategy for individuals whose income is too high for direct Roth IRA contributions. By contributing to a Traditional IRA and then converting those funds to a Roth IRA, investors may still gain access to the potential benefits of tax-free growth and qualified tax-free withdrawals in retirement.
If you are interested in investing in alternative assets such as real estate, a Roth IRA may allow potential investment gains to grow tax-free within the account. If you want to explore how a backdoor Roth IRA may fit into your retirement and investment strategy, consider scheduling a consultation to discuss a Self-Directed Roth IRA.
