What is the mega backdoor Roth?
The mega backdoor Roth uses after-tax 401(k) contributions beyond the $23,000 limit, converted to Roth. If your plan allows, you can contribute up to $69,000 total (2024), with after-tax portions converted to Roth.
Does my 401k plan allow mega backdoor Roth?
Not all plans do. Your plan needs: 1) after-tax contribution option, and 2) in-service withdrawals or in-plan Roth conversions. Check with your HR or plan administrator.
How is mega backdoor different from regular backdoor Roth?
Regular backdoor Roth uses IRA and is limited to $7,000/year. Mega backdoor uses 401(k) after-tax contributions and can allow $30,000-40,000+ additional per year, depending on employer match and contributions.
What happens to growth on after-tax contributions?
Growth on after-tax contributions is taxable when converted. For maximum benefit, convert frequently (daily or per-paycheck) to minimize taxable growth. Some plans offer automatic conversion.
