Can You Put Money in a Solo K or SEP IRA?

The total amount you can max is similar, not identical. In essence, I can put 66 grand a year into a solo K or SEP IRA. You can have both Roth and traditional money in both. That's new with the secure act like 30 days ago. But if you're really wanting to put down big money, okay. It is nine times out of 10, the 401K is going to win.
