For high-income earners, contributing via the “front door” to a Roth IRA is often unavailable due to IRS income limits. In 2026, eligibility to contribute directly to a Roth IRA begins to phase out at a Modified Adjusted Gross Income (MAGI) of $153,000 (Single) or $242,000 (Married Filing Jointly). Once MAGI exceeds $168,000 (Single) or $252,000 (Married Filing Jointly), direct contributions are no longer permitted.

However, the “backdoor Roth IRA” remains a legal and widely used strategy to achieve tax-free growth and tax-free retirement income.

How It Works

1. Make a nondeductible Traditional IRA contribution

• You can contribute to a Traditional IRA regardless of income. For 2026, the contribution limit is $7,500 (or $8,600 if age 50+).
• For high-income earners, this contribution is typically made with after-tax dollars and is not deductible.

2. Convert the Traditional IRA to a Roth IRA

• After the contribution settles, you convert those Traditional IRA funds into a Roth IRA.
• Because you already paid taxes on the contribution, the conversion is generally not taxable—as long as you do not have other pre-tax IRA balances and the contribution has not generated earnings.
• Timing note: Many investors complete the conversion shortly after the contribution to minimize any taxable gains that could occur between steps.

Going “Mega”: Backdoor vs. Mega Backdoor

If you have already maxed out IRA contributions and want to invest more on a tax-advantaged basis, your employer-sponsored 401(k) or 403(b) may allow an expanded strategy known as the Mega Backdoor Roth.

This strategy uses after-tax contributions inside an employer plan and can allow significantly higher Roth conversions.

In 2026, you may be able to contribute up to approximately $47,500 in after-tax dollars, depending on your plan design.

The total annual limit across all contributions (employee deferrals + employer contributions + after-tax contributions) is $72,000 under IRC Section 415(c).

How the “Mega” math works:

Start with the $72,000 total plan limit, then subtract:

• Your $24,500 salary deferral  for 2026 (Plus any catch-ups if over age 50)
• Any employer contributions

The remaining amount is the potential space for after-tax contributions that may be converted to Roth.

Important: Not all employer plans allow this strategy. The plan must permit:

This is the most common pitfall.

The IRS treats all Traditional, SEP, and SIMPLE IRAs as one combined bucket. If you have existing pre-tax IRA balances, a portion of your Roth conversion may be taxable—even if your new contribution was made with after-tax dollars.

Potential solution: In some cases, a “reverse rollover” (moving pre-tax IRA funds into an employer-sponsored plan, if allowed) may help reduce or eliminate this issue. This should be evaluated carefully.
