My wife is a sole proprietor Dentist. I perform odd jobs like purchasing supplies, and simple repairs, in addition to billing ang bookkeeping. I have another fulltime job. Can she pay me on a 1099-misc? Can I then file a second schedule C and deduct expenses on automobile, computer and phone?
We file as "married filing jointly". My primary salary (main W2 job) is more than the Social Security threshold.

Thanks
