Can I Make A Mega Backdoor Roth Contribution?

In certain cases, clients may be eligible to make a Mega Backdoor Roth contribution. At a high level, this involves a client making a non-Roth, after-tax contribution to their 401(k), then rolling it out of their 401(k) into a Roth IRA. Under the right circumstances, this can allow the client to contribute tens of thousands of dollars into a Roth IRA. However, the rules are very restrictive and prohibitive for most clients, and can be difficult to navigate.
