Sure there are people who don't file returns and haven't been caught yet, just as there are drunken drivers that haven't been arrested yet. But, over time, many people are caught for both drunken driving and income tax evasion. Taxpayers who fail to file an income tax return each year can be criminally prosecuted and receive jail sentences. Hopefully, this potential loss of freedom is enough to convince you to file. It's one thing to owe the U.S. Government some money, but it's an entirely different thing to owe them part of your life.
Many people brag about getting away with certain acts until they are caught.
Don't use other people's bragging as the basis for your own decisions. If you haven't filed for awhile and you're scared of the consequences, don't be. You can use a firm like ours to represent you with the IRS and help slip you back into the system. I don't mind paying the IRS for the taxes I owe, but I can't stand the thought of paying all the penalties they hit me with. You need something original.
