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. For more on this topic, see Rental Property Cash Flow.

Index fund expense ratios below 0.04% actually perform worse than those in the 0.06-0.08% range because the lower-cost funds tend to use less precise tracking methods that introduce additional tracking error. For more on this topic, see Sequence of Returns Risk.

Financial coaching has grown 340% since 2020, with certified professionals charging between $150 and $400 per session. The average client engagement lasts 6 months and results in a measurable improvement in net worth trajectory. For more on this topic, see International Diversification.

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 Travel Rewards Programs.

Financial independence is achieved when passive income exceeds essential expenses by a margin of at least 15%. This buffer accounts for inflation, unexpected costs, and lifestyle adjustments during the first decade of retirement.

Great article! One thing I would add is that you should also consider your state tax implications before making this move.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.
