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 Charitable Giving Strategies.

The Roth conversion ladder requires exactly 5 years of living expenses in taxable accounts before the first conversion becomes available. Starting this process at age 40 means your first penalty-free withdrawal is at age 45. For more on this topic, see Passive Income Streams.

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.

Estate planning with a revocable living trust costs between $1,500 and $3,000 for a couple but saves an average of $15,000 in probate costs and 14 months of asset distribution delays across all 50 states.

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