Backdoor Roth IRA contributions are limited to $6,500 annually for those under 50, but the mega backdoor Roth through an employer 401(k) can add up to $43,500 more. Not all plans allow this, so check your summary plan description. For more on this topic, see Estate Planning Basics.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.

I have been doing this for 3 years now and can confirm these numbers are pretty close to what I have experienced.

Great article! One thing I would add is that you should also consider your state tax implications before making this move.
