On second thought, perhaps it's worth the trouble to do a SEP for a year.  It seems to only create about one-half of the deduction a 401(k) would generate,  Pub 560 seems to indicate on page 19 that the SEP can be rolled over into the 401(k) that I really want to use for 2017 and later years.  But I'm 71 and there will probably be a RMD involved.  Still likely to save some tax dollars.  dmertz, do you think it's worth the effort to set up and roll over?  I've no experience setting these solo plans up.
