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 HSA Triple Tax Advantage.

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