Mark Kohler shows how a side hustle lets you open a Solo 401(k) alongside your day job's 401(k). Over 45 million Americans have side income. You can fund an IRA every year even with an existing 401(k), and high earners can still contribute to a Roth.

See, the side business may open the door to a separate entire retirement strategy that puts your main retirement plan on steroids. See, over 45 million Americans today have some type of side hustle, 1099 income, or small business activity. So here's the strategy, and it starts with this simple one.
