Meta Employee Builds $750K Roth Wealth via Mega Backdoor 401(k) Strategy

Meta Engineer Builds Massive Roth Wealth

A 30-year-old software engineer at Meta (NASDAQ:META), earning a $200,000 base salary plus refreshing stock grants, used the "Mega Backdoor Roth" strategy to build $750,000 in Roth savings in just six years. This strategy allows high-income employees to convert after-tax 401(k) contributions into Roth accounts, bypassing income limits for direct Roth IRA contributions.

Strategy Details

The strategy leverages after-tax contributions in 401(k) plans, which allow additional contributions beyond the pre-tax deferral limit ($23,500 for 2026). These after-tax contributions can be converted to Roth 401(k) or Roth IRA via an in-plan Roth rollover, known as the Mega Backdoor Roth. The total 401(k) contribution limit for 2026 is $70,000 (or $77,500 for those over 50).

Context

This strategy is popular among high-income tech workers who exceed income limits for direct Roth IRA contributions ($161,000 for individuals in 2026). Meta allows after-tax contributions, enabling the engineer to accumulate significant Roth wealth.

What This Means for Investors

For investors, this story highlights the importance of understanding available 401(k) plan options, especially for high-income earners. The Mega Backdoor Roth strategy can be a powerful tool to maximize tax-free retirement savings, but it requires a 401(k) plan that supports after-tax contributions and in-plan Roth rollovers.
