My 1099 income is only about $5k. From the MMM thread, discount solo 401k is about $575 the first year and $100 each subsequent year you do the mega backdoor roth. At the moment I am thinking it would be cost effective, since even though $3000 is a paltry sum that would otherwise go in a taxable account, the capital gains tax I would pay several decades from now would exceed it. And currently, my future plans are to transition to part time locums work when this would be more a more useful strategy, but that would still justify the upfront $575 cost. I’ll wait till the end of the year before I decide how to play this. I’ve never even opened a solo 401k before, so this would be an interesting adventure.
