new health care law PRACTICAL question?

i'm not so much interested in political view points or if it's a good or bad thing, but, i'm wondering how it will affect self employed folks who file 1040 long, schedule SE and may claim less income than they really make, (cash is king!). if a 1099 is involved, that's the income that is reported.

SO, let's say somebody who is self employed claims 15,000 in income. that's not much and said somebody pays FICA and SS tax on 15K. does the new law put that person on his states medi caide or what? how's this thing a ma jig gonna work? thank you. jim
