A 401(k) mega backdoor Roth is a strategy that allows high-income earners to save even more for retirement. It's a clever way to use the 401(k) plan to your advantage, but it does require some specific conditions to be met.

To start, you need to make the maximum pre-tax contribution to your 401(k) for the year, which is $23,000 for all accounts in 2024, or $30,500 for those aged 50 and over.

Once you've reached your pre-tax contribution limit, you can make additional after-tax contributions up to the total 401(k) limit for the year, which is $69,000 or $76,500 for those aged 50 and over.

The after-tax contributions are then converted into a Roth account, allowing the money to grow tax-free and be withdrawn tax-free in retirement.

Not all 401(k) plans allow this strategy, so it's essential to review your 401(k) documents to understand your plan's features and restrictions.

Only about 11% of 401(k) plans permitted mega backdoor Roth conversions at the end of 2023, according to data from Fidelity Investments, so it's crucial to check if your plan is one of them.

Here are the key steps to a 401(k) mega backdoor Roth:

Keep in mind that conversions could trigger a tax event, so it's best to consult with a tax professional about your specific situation.
