Retirement tax questions

For what it's worth, for someone under age 50 who is not maxing out the Social Security wage base at another employer, this particular limitation is the limiting factor for 2017 only between $19,370 and $32,275 of net profit.  Below that range there is no employer contribution (the maximum contribution is achieved by making it all elective deferral) and above that range net profit is sufficient to support the full employer contribution of 20% of net earnings (until the overall limit of $54,000 is reached).
