what threshold to move from sep to solo401k?
user
i think this article explains it pretty well: contributions to a sep are limited to   20% of your business  income (which is   business income minus half of your   self-employment tax), up to a maximum   of $45,000. with a solo 401(k), on the   other hand, you can contribute up to   $15,500 plus 20% of your business   income (defined the same way as   above), with a maximum contribution of   $45,000 in 2007. you can make an extra   $5,000 catch-up contribution if you're   50 or older
