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.

The math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.

Can you do a follow-up article about how this applies to people with variable income? Like freelancers and consultants?

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.
