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.

Has anyone tried this with a single income household? We are a one-income family and wondering if the same principles apply.

Can you do a follow-up article about how this applies to people with variable income? Like freelancers and consultants?
