Question: Can you get in trouble for trying to buy beer but not buying it with a fake id?
Answer: Yes. A person under the legal drinking age who misrepresents their age by using a written form of identification with the intent to have another person sell, give or furnish alcohol to them is guilty of a class one (1) misdemeanor.
Since your question was about an attempt to buy beer, the attempt changes the class one (1) to a class two (2) misdemeanor. A class two (2) misdemeanor is punishable by up to four (4) months in jail and a fine of up to $750.
However, using a forged document (the fake ID), you would be guilty of a class four (4) FELONY. This is punishable by up to three (3) years in prison and a fine of $150,000.
