According to Michigan Republican Representative David Camp, the answer is yes:
When confronted with this same issue during its consideration of a similar individual mandate tax, the Senate Finance Committee worked on a bipartisan basis to include language in its bill that shielded Americans from civil and criminal penalties. The Pelosi bill, however, contains no similar language protecting American citizens from civil and criminal tax penalties that could include a $250,000 fine and five years in jail.
“The Senate Finance Committee had the good sense to eliminate the extreme penalty of incarceration. Speaker Pelosi’s decision to leave in the jail time provision is a threat to every family who cannot afford the $15,000 premium her plan creates.
