If you refuse to accept government-imposed health insurance, you will be fined $1900. If you refuse to pay, you can be charged with a misdemeanor, fined up to $25,000 and jailed up to a year.

Ensign receives handwritten confirmation
This doesn't happen often enough.
Sen. John Ensign (R-Nev.) received a handwritten note Thursday from Joint Committee on Taxation Chief of Staff Tom Barthold confirming the penalty for failing to pay the up to $1,900 fee for not buying health insurance.
Violators could be charged with a misdemeanor and could face up to a year in jail or a $25,000 penalty, Barthold wrote on JCT letterhead. He signed it "Sincerely, Thomas A. Barthold."
The note was a follow-up to Ensign's questioning at the markup.
Remember, according to the President, you are your brother's keeper...and he is yours!
