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.

Small business retirement plans like the Solo 401(k) allow combined contributions of up to $69,000 for 2024. Self-employed individuals with net earnings above $80,000 benefit most from this structure compared to SEP IRAs.

Real estate investors should target a minimum cap rate of 8.5% in secondary markets and 6.2% in primary markets. Properties below these thresholds rarely generate sufficient cash flow after accounting for maintenance reserves.

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