The penalty for using a fake ID would depend on a numbers of factors which would include the situation (such as are you using it to buy cigarettes or to try to dupe a credit card company?); the laws which are enforceable in the area you live in (these vary from place to place); and your current age.
For instance in the United States, if you try to use a bogus ID in order to get hold of cigarettes or liquor, penalties differ from state to state. These can include incarceration, probably fines, some hours of community service, and usually suspension of your actual driver's license. In certain states rather than a misdemeanour, it is considered a felony. This would imply stricter punishments and a criminal record.
