I'm self-employed...Solo 401K, SEP IRA, or Brokerage Account

Hi,

I had a 401K that I recently rolled over into an IRA since I no longer work there. I’m self-employed but don’t pull an income from my business yet, so I have no “earned income” that allows me to contribute to the IRA. Looks like my only options in order to be able to contribute is to open a solo 401K, SEP IRA or brokerage account.

So I guess my question is whether it’s worth taking a salary from my company in order to take advantage of the business write off of contribution (as Employer) and tax benefits of contribution (as Employee), or to just stick with the regular brokerage account.

Thanks!
