Mega Backdoor Roth IRA

Advanced strategy to maximize Roth contributions beyond standard limits

What is the Mega Backdoor Roth IRA?

The Mega Backdoor Roth IRA is an advanced tax optimization strategy that allows high-income earners to contribute significantly more money to Roth accounts than the standard contribution limits allow. This strategy can potentially allow you to contribute up to $69,000total to your 401(k) plan in 2024, with a large portion going to Roth accounts.

This strategy is particularly valuable for high-income earners who are limited in their ability to contribute to Roth IRAs due to income limits, but have access to employer 401(k) plans that support this advanced feature.

How the Mega Backdoor Roth Works

💰 After-Tax 401(k) Contributions

Make after-tax contributions to your 401(k) plan beyond the standard $23,000 limit. These contributions don't provide immediate tax benefits but can be converted to Roth.

🔄 In-Service Distribution

Convert your after-tax 401(k) contributions to a Roth IRA through an in-service distribution. This allows the money to grow tax-free in the Roth account.

📈 Tax-Free Growth

Once converted to Roth, your money grows tax-free and can be withdrawn tax-free in retirement (after age 59½ and 5-year holding period).

⚠️ Plan Requirements

Your employer's 401(k) plan must allow both after-tax contributions and in-service distributions. Not all plans offer these features.

2024 Contribution Limits

The Mega Backdoor Roth strategy takes advantage of the total 401(k) contribution limits, which are much higher than the standard employee contribution limits.

Total 401(k) Limits (2024)

  • Under age 50:$69,000
  • Age 50 and over:$76,500

Breakdown

  • • Employee pre-tax/Roth: $23,000
  • • Employer match: Varies
  • • After-tax contributions: Up to remaining limit
  • • Catch-up contributions: +$7,500 (age 50+)

Example: Maximum Mega Backdoor Roth

Here's how you could maximize the Mega Backdoor Roth strategy in 2024:

Scenario: Under Age 50, $5,000 Employer Match

Employee pre-tax/Roth contributions$23,000
Employer match$5,000
After-tax contributions (Mega Backdoor)$41,000
Total 401(k) contributions$69,000

Result: You could potentially convert $41,000 to a Roth IRA, giving you significant tax-free growth potential.
