Best way for stay at home mom to save


Hi All,

My wife and I are big savers. I work full time and my wife stays home with the kiddos. we max out 401k, HSA, both Roth IRAs, and save into a brokerage account.

My wife started a little side hustle and I’m looking for the best way to save her money. We don’t need the money and I don’t want it to be taxed at my income level. What are the best options to save into? Opening up a solo 401k for her?
