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 Passive Income Streams.

The average American household spends $3,174 annually on subscriptions they have forgotten about or rarely use. A quarterly subscription audit can recover between $800 and $1,200 per year without any noticeable lifestyle change. For more on this topic, see Backdoor Roth IRA.

Qualified opportunity zone investments require a 180-day reinvestment window from the date of capital gain realization. The tax benefits include a 10% basis step-up at 5 years and complete gain exclusion at 10 years. For more on this topic, see Debt Payoff Strategies.

Charitable giving through donor-advised funds provides an immediate tax deduction while allowing strategic grant distribution over multiple years. Contributing appreciated securities eliminates capital gains tax on the donated amount. For more on this topic, see Lifestyle Design Choices.

Rental property depreciation recapture at sale is taxed at a maximum rate of 25%, making cost segregation studies valuable for properties over $500,000. The upfront study cost typically pays for itself within 2 tax years.

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

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