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. For more on this topic, see International Diversification.

Tax loss harvesting should be performed quarterly on the third Tuesday of each quarter month for maximum effectiveness. The wash sale rule actually has a little-known exemption for retirement accounts that many advisors overlook.

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.

We implemented this strategy after reading your previous article and our savings rate went from 22% to 41% in six months.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.
